Forget About the “Corona Bond.” Should the ECB Purchase Eurozone Government Bond ETFs?

By Elham Saeidinezhad

In recent history, one of a few constants about the European Union (EU) is that it follows the U.S. footstep after any disaster. After the COVID-19 crisis, the Fed expanded the scope and duration of the Municipal Liquidity Facility (MLF) to ease the fiscal conditions of the states and the cities. The facility enables lending to states and municipalities to help manage cash flow stresses caused by the coronavirus pandemic. In a similar move, the ECB expanded its support for the virus-hit EU economies in response to the coronavirus pandemic. Initiatives such as Pandemic Emergency Purchase Programme (PEPP) allow the ECB to open the door to buy Greek sovereign bonds for the first time since the country’s sovereign debt crisis by announcing a waiver for its debt. 

There the similarity ends. While the market sentiment about the Fed’s support program for municipals is very positive, a few caveats in the ECB’s program have made the Union vulnerable to a market run. Fitch has just cut Italy’s credit rating to just above junk. The problem is that unlike the U.S., the European Union is only a monetary union, and it does not have a fiscal union. The investors’ prevailing view is that the ECB is not doing enough to support governments of southern Europe, such as Spain, Italy, and Greece, who are hardest hit by the virus. Anxieties about the Union’s fiscal stability are behind repeated calls for the European Union to issue common eurozone bonds or “corona bond.” Yet, the political case, especially from Northern European countries, is firmly against such plans. Further, despite the extreme financial needs of the Southern countries, the ECB is reluctant to lift its self-imposed limits not to buy more than a third of the eligible sovereign bonds of any single country and to purchase sovereign bonds in proportion to the weight of each country’s investment in its capital. This unwillingness is also a political choice rather than an economic necessity.

It is in that context that this piece proposes the ECB to include the Eurozone government bond ETF to its asset purchasing program. Purchasing government debts via the medium of the ETFs can provide the key to the thorny dilemma that is shaking the foundation of the European Union. It can also be the right step towards creating a borrowing system that would allow poorer EU nations to take out cheap loans with the more affluent members guaranteeing the funds would be returned. The unity of EU members faces a new, painful test with the coronavirus crisis. This is why the Italian Prime Minister Guiseppe Conte warned that if the bloc fails to stand up to it, the entire project might “lose its foundations.” The ECB’s decision to purchase Eurozone sovereign debt ETFs would provide an equal opportunity for all the EU countries to meet the COVID-19 excessive financial requirements at an acceptable price. Further, compared to the corona bond, it is less politically incorrect and more common amongst the central bankers, including those at the Fed and the Bank of Japan.

In the index fund ecosystem, the ETFs are more liquid and easier to trade than the basket of underlying bonds. What lies behind this “liquidity transformation” is the different equilibrium structure and the efficiency properties in markets for these two asset classes. In other words, the dealers make markets for these assets under various market conditions. In the market for sovereign bonds, the debt that is issued by governments, especially countries with lower credit ratings, do not trade very much. So, the dealers expect to establish long positions in these bonds. Such positions expose them to the counterparty risk and the high cost of holding inventories. Higher price risk and funding costs are correlated with an increase in spreads for dealers. Higher bid-ask spreads, in turn, makes trading of sovereign debt securities, especially those issued by countries such as Italy, Spain, Portugal, and Greece, more expensive and less attractive.

On the contrary, the ETFs, including the Eurozone government bond ETFs, are considerably more tradable than the underlying bonds for at least two reasons. First, the ETF functions as the “price discovery” vehicle because this is where investors choose to transact. The economists call the ETF a price discovery vehicle since it reveals the prices that best match the buyers with the sellers. At these prices, the buying and selling quantities are just in balance, and the dealers’ profitability is maximized. According to Treynor Model, these “market prices” are the closest thing to the “fundamental value” as they balance the supply and demand. Such an equilibrium structure has implications for the dealers. The make markers in the ETFs are more likely to have a “matched book,” which means that their liabilities are the same as their assets and are hedged against the price risk. The instruments that are traded under such efficiency properties, including the ETFs, enjoy a high level of market liquidity.

Second, traders, such as asset managers, who want to sell the ETF, would not need to be worried about the underlying illiquid bonds. Long before investors require to acquire these bonds, the sponsor of the ETF, known as “authorized participants” will be buying the securities that the ETF wants to hold. Traditionally, authorized participants are large banks. They earn bid-ask spreads by providing market liquidity for these underlying securities in the secondary market or service fees collected from clients yearning to execute primary trades. Providing this service is not risk-free. Mehrling makes clear that the problem is that supporting markets in this way requires the ability to expand banks’ balance sheets on both sides, buying the unwanted assets and funding that purchase with borrowed money. The strength of banks to do that on their account is now severely limited. Despite such balance sheet constraints, by acting as “dealers of near last resort,” banks provide an additional line of defense in the risk management system of the asset managers. Banks make it less likely for the investors to end up purchasing the illiquid underlying assets.

That the alchemists have created another accident in waiting has been a fear of bond market mavens and regulators for several years. Yet, in the era of COVID-19, the alchemy of the ETF liquidity could dampen the crisis in making by boosting virus-hit countries’ financial capacity. Rising debt across Europe due to the COVID-19 crisis could imperil the sustainability of public finances. This makes Treasury bonds issued by countries such as Greece, Spain, Portugal, and Italy less tradable. Such uncertainty would increase the funding costs of external bond issuance by sovereigns. The ECB’s attempt to purchase Eurozone government bonds ETFs could partially resolve such funding problems during the crisis. Further, such operations are less risky than buying the underlying assets.

Some might argue the ETFs create an illusion of liquidity and expose the affluent members of the ECB to an unacceptably high level of defaults by the weakest members. Yet, at least two “real” elements, namely the price discovery process and the existence of authorized participants who act as the dealers of the near last resort, allows the ETFs to conduct liquidity transformation and become less risky than the underlying bonds. Passive investing sometimes is called as “worse than Marxism.” The argument is that at least communists tried to allocate resources efficiently, while index funds just blindly invest according to an arbitrary benchmark’s formula. Yet, devouring capitalism might be the most efficient way for the ECB to circumvent political obstacles and save European capitalism from itself.

Can Central Bank Digital Currency Contain COVID-19 Crisis by Saving Small Businesses?

By Elham Saeidinezhad and Jack Krupinski

This Piece Is Part of the “Search For Stable Liquidity Providers” Series. It is also a follow up to our previous Money View article on the banking system during the COVID-19 crisis.

The COVID-19 crisis created numerous financial market dislocations in the U.S., including in the market for government support. The federal government’s Paycheck Protection Program offered small businesses hundreds of billions of dollars so they could keep paying employees. The program failed to a great extent. Big companies got small business relief money. The thorny problem for policymakers to solve is that the government support program is rooted in the faith that banks are willing to participate in. Banks were anticipated to act as an intermediary and transfer funds from the government to the small businesses. Yet, in the modern financial system, banks have already shifted gear away from their traditional role as a financial intermediary between surplus and deficit agents. Part l used the “Money View” and a historical lens to explain why banks are reluctant to be financial intermediaries and are more in tune with their modern function as dealers in the wholesale money markets. In Part ll, we are going to propose a possible resolution to this perplexity. In a monetary system where banks are not willing to be financial intermediaries, central banks might have to seriously entertain the idea of using central bank digital currency (CBDC) during a crisis. Such tools enable central banks to circumvent the banking system and inject liquidity directly to those who need it the most, including small and medium enterprises, who have no access to the capital market.

The history of central banking began with a simple task of managing the quantity of money. Yet, central bankers shortly faced a paradox between managing “survival constraint” in the financial market and the real economy. On the one hand, for banks, the survival constraint in the financial market takes the concrete form of a “reserve constraint” because banks settle net payments using their reserve accounts at the central bank. On the other hand, according to the monetarist idea, for money to have a real purchasing power in terms of goods and services, it should be scarce. Developed by the classical economists in the nineteenth and early twentieth centuries, the quantity theory of money asserted that the quantity of money should only reflect the level of transactions in the real economy.

The hybridity between the payment system and the central bank money created such a practical dilemma. Monetarist idea disregarded such hybridity and demanded that the central bank abandon its concern about the financial market and focus only on controlling the never-materializing threat of inflation. The monetarist idea was doomed to failure for its conjectures about the financial market, and its illusion of inflation. In the race to dominate the whole economy, an efficiently functioning financial market soon became a pre-condition to economic growth. In such a circumstance, the central bank must inject reserves or else risk a breakdown of the payments system. Any ambiguity about the liquidity problems (the survival constraint) for highly leveraged financial institutions would undermine central banks’ authority to maintain the monetary and financial stability for the whole economy. For highly leveraged institutions, with financial liabilities many times larger than their capital base, it doesn’t take much of a write-down to produce technical insolvency.

This essential hybridity, and the binding reality of reserve constraint, gave birth to two parallel phenomena. In the public sphere, the urge to control the scarce reserves originated monetary policy. The advantage that the central bank had over the financial system arose ultimately from the fact that a bank that does not have sufficient funds to make a payment must borrow from the central bank. Central bankers recognized that they could use this scarcity to affect the price of money, the interest rate, in the banking system. It is the central bank’s control over the price and availability of funds at this moment of necessity that is the source of its control over the financial system. The central bank started to utilize its balance sheet to impose discipline when there was an excess supply of money, and to offer elasticity when the shortage of cash is imposing excessive discipline. But ultimately central bank was small relative to the system it engages. Because the central bank was not all-powerful, it must choose its policy intervention carefully, with a full appreciation of the origins of the instability that it is trying to counter. Such difficult tasks motivated people to call central banking as the “art,” rather than the “science”.

In the private domain, the scarcity of central bank money significantly increased the reliance on the banking system liabilities. By acting as a special kind of intermediary, banks rose to the challenge of providing funding liquidity to the real economy. Their financial intermediation role also enabled them to establish the retail payment system. For a long time, the banking system’s major task was to manage this relationship between the (retail) payment system and the quantity of money. To do so, they transferred the funds from the surplus agents to the deficit agents and absorbed the imbalances into their own balance sheets. To strike a balance between the payment obligations, and the quantity of money, banks started to create their private money, which is called credit. Banks recognized that insufficient liquidity could lead to a cascade of missed payments and the failure of the payment system as a whole.

For a while, banks’ adoption of the intermediary role appeared to provide a partial solution to the puzzle faced by the central bankers. Banks’ traditional role, as a financial intermediary, connected them with the retail depositors. In the process, they offered a retail payment- usually involve transactions between two consumers, between consumers and small businesses, or between two small to medium enterprises. In this brave new world, managing the payment services in the financial system became analogous to the management of the economy as a whole.

Most recently, the COVID-19 crisis has tested this partial equilibrium again. In the aftermath of the COVID-19 outbreak, both the Fed and the U.S. Treasury coordinated their fiscal and monetary actions to support small businesses and keep them afloat in this challenging time. So far, a design flaw at the heart of the CARES Act, which is an over-reliance on the banking system to transfer these funds to small businesses, has created a disappointing result. This failure caught central bankers and the governments by surprise and revealed a fatal flaw in their support packages. At the heart of this misunderstanding is the fact that banks have already switched their business models to reflect a payment system that has been divided into two parts: wholesale and retail. Banks have changed the gear towards providing wholesale payment-those made between financial institutions (e.g., banks, pension funds, insurance companies) and/or large (often multinational) corporations- and away from retail payment. They are so taken with their new functions as dealers in the money market and originators of asset-backed securities in the modern market-based finance that their traditional role of being a financial intermediary has become a less important part of their activities. In other words, by design, small businesses could not get the aid money as banks are not willing to use their balance sheets to lend to these small enterprises anymore.

In this context, the broader access to central bank money by small businesses could create new opportunities for retail payments and the way the central bank maintains monetary and financial stability. Currently, households and (non-financial) companies are only able to use central bank money in the form of banknotes. Central bank digital currency (CBDC) would enable them to hold central bank money in electronic form and use it to make payments. This would increase the availability and utility of central bank money, allowing it to be used in a much more extensive range of situations than physical cash. Central bank money (whether cash, central bank reserves or potentially CBDC) plays a fundamental role in supporting monetary and financial stability by acting as a risk-free form of money that provides the ultimate means of settlement for all payments in the economy. This means that the introduction of CBDC could enhance the way the central bank maintains monetary and financial stability by providing a new form of central bank money and new payment infrastructure. This could have a range of benefits, including strengthening the pass-through of monetary policy changes to the broader economy, especially to small businesses and other retail depositors, and increasing the resilience of the payment system.

This increased availability of central bank money is likely to lead to some substitution away from the forms of payment currently used by households and businesses (i.e., cash and bank deposits). If this substitution was extensive, it could reduce the reliance on commercial bank funding, and the level of credit that banks could provide as CBDC would automatically give access to central bank money to non-banks. This would potentially be useful in conducting an unconventional monetary policy. For example, the COVID-19 precipitated increased demand for dollars both domestically and internationally. Small businesses in the U.S. are increasingly looking for liquidity through programs such as the Paycheck Protection Program Liquidity Facility (PPPLF) so that those businesses can keep workers employed. In the global dollar funding market, central banks swap lines with the Fed sent dollars into other countries, but transferring those dollars to end-users would be even easier for central banks if they could bypass the commercial banking system.

Further, CBDC can be used as intraday liquidity by its holders, whereas liquidity-absorbing instruments cannot achieve the same, or can do so only imperfectly. At the moment, there is no other short-term money market instrument featuring the liquidity and creditworthiness of CBDC. The central bank would thus use its comparative advantage as a liquidity provider when issuing CBDC. The introduction of CBDC could also decrease liquidity risk because any agent could immediately settle obligations to pay with the highest form of money.

If individuals can hold current accounts with the central bank, why would anyone hold an account with high st commercial banks? Banks can still offer other services that a CBDC account may not provide (e.g., overdrafts, credit facilities, etc.). Moreover, the rates offered on deposits by banks would likely increase to retain customers. Consumer banking preferences tend to be sticky, so even with the availability of CBDC, people will probably trust the commercial banking system enough to keep deposits in their bank. However, in times of crisis, when people flee for the highest form of money (central bank money), “digital runs” on banks could cause problems. The central bank would likely have to increase lending to commercial banks or expand open market operations to sustain an adequate level of reserves. This would ultimately affect the size and composition of balance sheets for both central banks and commercial banks, and it would force central banks to take a more active role in the economy, for better or worse.

As part 1 pointed out, banks are already reluctant to play the traditional role of financial intermediary. The addition of CBDC would likely cause people to substitute away from bank deposits, further reducing the reliance on commercial banks as intermediaries.  CBDC poses some risks (e.g., disintermediation, digital bank runs, cybersecurity), but it would offer some new channels through which to conduct unconventional monetary policy. For example, the interest paid on CBDC could put an effective floor on money market rates. Because CBDC is risk-free (i.e., at the top of the money hierarchy), it would be preferred to other short-term debt instruments unless the yields of these instruments increased. While less reliance on banks by small businesses would contract bank funding, banks would also have more balance sheet freedom to engage in “market-making” operations, improving market liquidity. More importantly, it creates a direct liquidity channel between the central banks, such as the Fed, and non-bank institutions such as small and medium enterprises. Because central banks need not be motivated by profit, they could pay interest on CBDC without imposing fees and minimum balance requirements that profit-seeking banks employ (in general, providing a payment system is unprofitable, so banks extort profit wherever possible). In a sense, CBDC would be the manifestation of money as a public good. Everyone would have ready access to a risk-free store of value, which is especially relevant in the uncertain economic times precipitated by the COVID-19.

In a World Where Banks Do Not Aspire to be Intermediaries, Is It Time to Cut Out the Middlemen? (Part I)

This Piece Is Part of the “Search For Stable Liquidity Providers” Series.

By Elham Saeidinezhad

“Bankers have an image problem.” Marcy Stigum

Despite the extraordinary quick and far-reaching responses by the Fed and US Treasury, to save the economy following the crisis, the market sentiment is that “Money isn’t flowing yet.” Banks, considered as intermediaries between the government and troubled firms, have been told to use the liberated funds to boost financing for individuals and businesses in need. However, large banks are reluctant, and to a lesser extent unable, to make new loans even though regulators have relaxed capital rules imposed in the wake of the last crisis. This paradox highlights a reality that has already been emphasized by Mehrling and Stigum but erred in the economic orthodoxy.

To understand this reluctance by the banks, we must preface with a careful look at banking. In the modern financial system, banks are “dealers” or “market makers” in the money market rather than intermediaries between deficit and surplus agents. In many markets such as the UK and US, these government support programs are built based on the belief that banks are both willing and able to switch to their traditional role of being financial intermediaries seamlessly. This intermediation function enables banks to become instruments of state aid, distributing free or cheap lending to businesses that need it, underpinned by government guarantees.  This piece (Part l) uses the Money View and a historical lens to explain why banks are not inspired anymore to be financial intermediaries. In Part ll, we are going to propose a possible resolution to this perplexity. In a financial structure where banks are not willing to be financial intermediaries, central banks might have to seriously entertain the idea of using central bank digital currency (CBDC) during a crisis. Such tools enable central banks to circumvent the banking system and inject liquidity directly to those who need it the most.

Stigum once observed that bankers have, at times, an image problem. They are seen as the culprits behind the high-interest rates that borrowers must pay and as acting in ways that could put the financial system and the economy at risk, perhaps by lending to risky borrowers, when interest rates are low. Both charges reflect the constant evolution in banks’ business models that lead to a few severe misconceptions over the years. The first delusion is about the banks’ primary function. Despite the common belief, banks are not intermediaries between surplus and deficit agents anymore. In this new system, banks’ primary role is to act as dealers in money market securities, in governments, in municipal securities, and various derivative products. Further, several large banks have extensive operations for clearing money market trades for nonbank dealers. A final important activity for money center banks is foreign operations of two sorts: participating in the broad international capital market known as the Euromarket and operating within the confines of foreign capital markets (accepting deposits and making loans denominated in local currencies). 

Structural changes that have taken place on corporates’ capital structure and the emergence of market-based finance have led to this reconstruction in the banking system. To begin with, the corporate treasurers switched sources of corporate financing for many corporates from a bank loan to money market instruments such as commercial papers. In the late 1970s and early 1980s, when rates were high, and quality-yield spreads were consequently wide, firms needing working capital began to use the sale of open market commercial paper as a substitute for bank loans. Once firms that had previously borrowed at banks short term were introduced to the paper market, they found that most of the time, it paid them to borrow there. This was the case since money obtained in the credit market was cheaper than bank loans except when the short-term interest rate was being held by political pressure, or due to a crisis, at an artificially low level.

The other significant change in market structure was the rise of “money market mutual funds.” These funds provide more lucrative investment opportunities for depositors, especially for institutional investors, compared to what bank deposits tend to offer. This loss of large deposits led bank holding companies to also borrow in the commercial paper market to fund bank operations. The death of the deposits and the commercial loans made the traditional lending business for the banks less attractive. The lower returns caused the advent of the securitization market and the “pooling” of assets, such as mortgages and other consumer loans. Banks gradually shifted their business model from a traditional “originate-and-hold” to an “originate-to-distribute” in which banks and other lenders could originate loans and quickly sell them into securitization pools. The goal was to increase the return of making new loans, such as mortgages, to their clients and became the originators of securitized assets.

The critical aspect of these developments is that they are mainly off-balance sheet profit centers. In August 1970, the Fed ruled that funds channeled to a member bank that was raised through the sale of commercial paper by the bank’s holding company or any of its affiliates or subsidiaries were subject to a reserve requirement. This ruling eliminated the sale of bank holding company paper for such purposes. Today, bank holding companies, which are active issuers of commercial paper, use the money obtained from the sale of such paper to fund off-balance sheet, nonbank, activities. Off-balance sheet operations do not require substantial funding from the bank when the contracts are initiated, while traditional activities such as lending must be fully funded. Further, most of the financing of traditional activities happens through a stable base of money, such as bank capital and deposits. Yet, borrowing is the primary source of funding off-balance sheet activities.

To be relevant in the new market-based credit system, and compensate for the loss of their traditional business lines, the banks started to change their main role from being financial intermediaries to becoming dealers in money market instruments and originators of securitized assets. In doing so, instead of making commercial loans, they provide liquidity backup facilities on commercial paper issuance. Also, to enhance the profitability of making consumer loans, such as mortgages, banks have turned to securitization business and have became the originators of securitized loans. 

In the aftermath of the COVID-19 outbreak, the Fed, along with US Treasury, has provided numerous liquidity facilities to help illiquid small and medium enterprises. These programs are designed to channel funds to every corner of the economy through banks. For such a rescue package to become successful, these banks have to resume their traditional financial intermediary role to transfer funds from the government (the surplus agents) to SMEs (the deficit agents) who need cash for payroll financing. Regulators, in return, allow banks to enjoy lower capital requirements and looser risk-management standards. On the surface, this sounds like a deal made in heaven.

In reality, however, even though banks have received regulatory leniency, and extra funds, for their critical role as intermediaries in this rescue package, they give the government the cold shoulder. Banks are very reluctant to extend new credits and approve new loans. It is easy to portray banks as villains. However, a more productive task would be to understand the underlying reasons behind banks’ unwillingness. The problem is that despite what the Fed and the Treasury seem to assume, banks are no longer in the business of providing “direct” liquidity to financial and non-financial institutions. The era of engaging in traditional banking operations, such as accepting deposits and lending, has ended. Instead, they provide indirect finance through their role as money market dealers and originators of securitized assets.

In this dealer-centric, wholesale, world, banks are nobody’s agents but profits’. Being a dealer and earning a spread as a dealer is a much more profitable business. More importantly, even though banks might not face regulatory scrutiny if these loans end up being nonperforming, making such loans will take their balance sheet space, which is already a scarce commodity for these banks. Such factors imply that in this brave new world, the opportunity cost of being the agent of good is high. Banks would have to give up on some of their lucrative dealing businesses as such operation requires balance sheet space. This is the reason why financial atheists have already started to warn that banks should not be shamed into a do-gooder lending binge.

Large banks rejected the notion that they should use their freed-up equity capital as a basis for higher leverage, borrowing $5tn of funds to spray at the economy and keep the flames of coronavirus at bay. Stigum once said that bankers have an image problem. Having an image problem does not seem to be one of the banks’ issues anymore. The COVID-19 crisis made it very clear that banks are very comfortable with their lucrative roles as dealers in the money market and originators of assets in the capital market, and have no intention to be do-gooders as financial intermediaries. These developments could suggest that it is time to cut out banks as middlemen. To this end, central bank digital currency (CBDC) could be a potential solution as it allows central banks to bypass banks to inject liquidity into the system during a period of heightened financial distress such as the COVID-19 crisis.

Should the Fed Add FX Swaps to its Asset Purchasing Programs?

By Elham Saeidinezhad and Jack Krupinski*

“As Stigum reminded us, the market for Eurodollar deposits follows the sun around the globe. Therefore, no one, including and especially the Fed, can hide from its rays.”

The COVID-19 crisis renewed the heated debate on whether the US dollar could lose its status as the world’s dominant currency. Still, in present conditions, without loss of generality, the world reserve currency is the dollar. The exorbitant privilege implies that the deficit agents globally need to acquire dollars. These players probably have a small reserve holding, usually in the form of US Treasury securities. Still, more generally, they will need to purchase dollars in a global foreign exchange (FX) markets to finance their dollar-denominated assets. One of the significant determinants of the dollar funding costs that these investors face is the cost of hedging foreign exchange risk. Traditionally, the market for the Eurodollar deposits has been the final destination for these non-US investors. However, after the great financial crisis, investors have turned to a particular, and important segment of the FX market, called the FX swap market, to raise dollar funding. This shift in the behavior of foreign investors might have repercussions for the rates in the US money market.

The point to emphasize is that the price of Eurodollar funding, used to discipline the behavior of the foreign deficit agents, can affect the US domestic money market. This usage of FX swap markets by foreign investors to overcome US dollar funding shortages could move short-term domestic rates from the Fed’s target range. Higher rates could impair liquidity in US money markets by increasing the financing cost for US investors. To maintain the FX swap rate at a desirable level, and keep the Fed Funds rate at a target range, the Fed might have to include FX derivatives in its asset purchasing programs.

The use of the FX swap market to raise dollar funding depends on the relative costs in the FX swap and the Eurodollar market. This relative cost is represented in the spread between the FX swap rate and LIBOR. The “FX swap-implied rate” or “FX swap rate” is the cost of raising foreign currency via the FX derivatives market. While the “FX swap rate” is the primary indicator that measures the cost of borrowing in the FX swap market, the “FX-hedged yield curve” represents that. The “FX-hedged yield curve” adjusts the yield curve to reflect the cost of financing for hedged international investors and represents the hedged return. On the other hand, LIBOR, or probably SOFR in the post-LIBOR era, is the cost of raising dollar directly from the market for Eurodollar deposits.

In tranquil times, arbitrage, and the corresponding Covered Interest Parity condition, implies that investors are indifferent in tapping either market to raise funding. On the contrary, during periods when the bank balance sheet capacity is scarce, the demand of investors shifts strongly toward a particular market as the spread between LIBOR and FX swap rate increases sharply. More specifically, when the FX swap rate for a given currency is less than the cost of raising dollar directly from the market for Eurodollar deposits, institutions will tend to borrow from the FX swap market rather than using the money market. Likewise, a higher FX swap rate would discourage the use of FX swaps in financing.

By focusing on the dollar funding, it is evident that the FX swap market is fundamentally a money market, not a capital market, for at least two reasons. First, the overwhelming majority of the market is short-term. Second, it determines the cost of Eurodollar funding, both directly and indirectly, by providing an alternative route of funding. It is no accident that since the beginning of the COVID-19 outbreak, indicators of dollar funding costs in foreign exchange markets, including “FX swap-implied rate”, have risen sharply, approaching levels last seen during the great financial crisis. During crises, non-US banks usually finance their US dollar assets by tapping the FX swap market, where someone borrows dollars using FX derivatives by pledging another currency as collateral. In this period, heightened uncertainty leads US banks that face liquidity shortage to hoard liquid assets rather than lend to foreigners. Such coordinated decisions by the US banks put upward pressure on FX swap rates.

The FX swap market also affects the cost of Eurodollar funding indirectly through the FX dealers. In essence, most deficit agents might acquire dollars by relying entirely on the private FX dealing system. Two different types of dealers in the FX market are typical FX dealers and speculative dealers. The FX dealer system expedites settlement by expanding credit. In the current international order, the FX dealer usually has to provide dollar funding. The dealer creates a dollar liability that the deficit agent buys at the spot exchange rate using local currency, to pay the surplus country. The result is the expansion of the dealer’s balance sheet and its exposure to FX risk. The FX risk, or exchange risk, is a risk that the dollar price of the dealer’s new FX asset might fall. The bid-ask spread that the FX dealer earns reflects this price risk and the resulting cost of hedging.

As a hedge against this price risk, the dealer enters an FX swap market to purchase an offsetting forward exchange contract from a speculative dealer. As Stigum shows, and Mehrling emphasizes, the FX dealer borrows term FX currencies and lends term dollars. As a result of entering into a forward contract, the FX dealer has a “matched book”—if the dollar price of its new FX spot asset falls, then so also will the dollar value of its new FX term liability. It does, however, still face liquidity risk since maintaining the hedge requires rolling over its spot dollar liability position until the maturity of its term dollar asset position. A “speculative” dealer provides the forward hedge to the FX dealer. This dealer faces exposure to exchange risk and might use a futures position, or an FX options position to hedge. The point to emphasize here is that the hedging cost of the speculative dealer affects the price that the normal FX dealer faces when entering a forward contract and ultimately determines the price of Eurodollar funding. 

The critical question is, what connects the domestic US markets with the Euromarkets as mentioned earlier? In different maturity ranges, US and Eurodollar rates track each other extraordinarily closely over time. In other words, even though spreads widen and narrow, and sometimes rates cross, the main trends up and down are always the same in both markets. Stigum (2007) suggests that there is no doubt that this consistency in rates is the work of arbitrage.

Two sorts of arbitrages are used to link US and Eurodollar rates, technical and transitory. Opportunities for technical arbitrage vanished with the movement of CHIPS to same-day settlement and payment finality. Transitory arbitrages, in contrast, are money flows that occur in response to temporary discrepancies that arise between US and Eurodollar rates because rates in the two markets are being affected by differing supply and demand pressures. Much transitory arbitrage used to be carried on by banks that actively borrow and lend funds in both markets. The arbitrage that banks do between the domestic and Eurodollar markets is referred to as soft arbitrage. In making funding choices, domestic versus Eurodollars, US banks always compare relative costs on an all-in basis.

But that still leaves open the question of where the primary impetus for rate changes typically comes from. Put it differently, are changes in US rates pushing Eurodollar rates up and down, or vice versa? A British Eurobanker has a brief answer: “Rarely does the tail wag the dog. The US money market is the dog, the Eurodollar market, the tail.” The statement has been a truth for most parts before the great financial crisis. The fact of this statement has created a foreign contingent of Fed watchers. However, the direction of this effect might have reversed after the great financial crisis.  In other words, some longer-term shifts have made the US money market respond to the developments in the Eurodollar funding.

This was one of the lessons from the US repo-market turmoil. On Monday, September 16, and Tuesday, September 17, Overnight Treasury general collateral (GC) repurchase-agreement (repo) rates surprisingly surged to almost 10%. Two factors made these developments extraordinary: First, the banks, who act as a dealer of near last resort in this market due to their direct access to the Fed’s balance sheets, did not inject liquidity. Second, this time around, the Secured Overnight Financing Rate (SOFR), which is replacing LIBOR to measure the cost of Eurodollar financing, also increased significantly, leading the Fed to intervene directly in the repo market.

Credit Suisse’ Zoltan Poszar points out that an increase in the supply of US Treasuries along with the inversion in the FX-hedged yield of Treasuries has created such anomalies in the US money market.  Earlier last year, an increase in hedging costs caused the inversion of a curve that represents the FX-hedged yield of Treasuries at different maturities. Post- great financial crisis, the size of foreign demands for US assets, including the US Treasury bonds, increased significantly. For these investors, the cost of FX swaps is the primary factor that affects their demand for US assets since that hedge return, called FX-hedged yield, is an important component of total return on investment. This FX-hedged yield ultimately drives investment decisions as hedge introduces an extra cash flow that a domestic bond investment does not have. This additional hedge return affects liquidity considerations because hedging generates its own cash flows.

The yield-curve inversion disincentivizes foreign investors, mostly carry traders, trying to earn a margin from borrowing short term to buy Treasuries (i.e., lending longer-term). Demand for Eurodollars—which are required by deficit agents to settle payment obligations—is very high right now, which has caused the FX Swap rate-LIBOR spread to widen. The demand to directly raise dollars through FX swaps has driven the price increase, but this also affects investors who typically use FX swaps to hedge dollar investments. As the hedge return falls (it is negative for the Euro), it becomes less profitable for foreign investors to buy Treasury debt. More importantly, for foreign investors, the point at which this trade becomes unprofitable has been reached way before the yield curve inverted, as they had to pay for hedging costs (in yen or euro). This then forces Treasuries onto the balance sheets of primary dealers and have repercussions in the domestic money market as it creates balance sheet constraints for these large banks. This constraint led banks with ample reserves to be unwilling to lend money to each other for an interest rate of up to 10% when they would only receive 1.8% from the Fed.

This seems like some type of “crowding out,” in which demand for dollar funding via the FX swap has driven up the price of the derivative and crowded out those investors who would typically use the swap as a hedging tool. Because it is more costly to hedge dollar investments, there is a risk that demand for US Treasuries will decrease. This problem is driven by the “dual-purpose” of the FX swaps. By directly buying this derivative, the Fed can stabilize prices and encourage foreign investors to keep buying Treasuries by increasing hedge return. Beyond acting to stabilize the global financial market, the Fed has a direct domestic interest in intervening in the FX market because of the spillover into US money markets.

The yield curve that the Fed should start to influence is the FX-hedged yield of Treasuries, rather than the Treasury yield curve since it encompasses the costs of US dollar funding for foreigners. Because of the spillover of FX swap turbulences to the US money markets, the FX swap rate will influence the US domestic money market. If we’re right about funding stresses and the direction of effects, the Fed might have to start adding FX swaps to its asset purchasing program. This decision could bridge the imbalance in the FX swap market and offer foreign investors a better yield. The safe asset – US Treasuries – is significantly funded by foreign investors, and if the FX swap market pulls balance sheet and funding away from them, the safe asset will go on sale. Treasury yields can spike, and the Fed will have to shift from buying bills to buying what matters– FX derivatives. Such ideas might make some people- especially those who believe that keeping the dollar as the world’s reserve currency is a massive drag on the struggling US economy and label the dollar’s international status as an “an exorbitant burden,”- uncomfortable. However, as Stigum reminded us, the market for Eurodollar deposits follows the sun around the globe. Therefore, no one, including and especially the Fed, can hide from its rays.
