Can Algorithmic Market Makers Safely Replace FX Dealers as Liquidity Providers?

By Jack Krupinski
(This Money View piece is by my students, Jack Krupinski. Jack is currently a fourth-year student at UCLA, majoring in Mathematics/Economics with a minor in statistics.)

Financialization and electronification are long term economic trends and are here to stay. It’s essential to study how these trends will alter the world’s largest market—the foreign exchange (FX) market. In the past, electronification expanded access to the FX markets and diversified the demand side. Technological developments have recently started to change the FX market’s supply side, away from the traditional FX dealing banks towards principal trading firms (PTFs). Once the sole providers of liquidity in FX markets, dealers are facing increased competition from PTFs. These firms use algorithmic, high-frequency trading to leverage speed as a substitute for balance sheet capacity, which is traditionally used to determine FX dealers’ comparative advantage. Prime brokerage services were critical in allowing such non-banks to infiltrate the once impenetrable inter-dealer market. Paradoxically, traditional dealers were the very institutions that have offered prime brokerage services to PTFs, allowing them to use the dealers’ names and credit lines while accessing trading platforms. The rise of algorithmic market markers at the expense of small FX dealers is a potential threat to long-term stability in the FX market, as PTFs’ resilience to shocks is mostly untested. The PTFs presence in the market, and the resulting narrow spreads, could create an illusion of free liquidity during normal times. However, during a crisis, such an illusion will evaporate, and the lack of enough dealers in the market could increase the price of liquidity dramatically. 

In normal times, PTFs’ presence could create an “illusion of free liquidity” in the FX market. The increasing presence of algorithmic market makers would increase the supply of immediacy services (a feature of market liquidity) in the FX market and compress liquidity premia. Because liquidity providers must directly compete for market share on electronic trading platforms, the liquidity price would be compressed to near zero. This phenomenon manifests in a narrower inside spread when the market is stable.  The FX market’s electronification makes it artificially easier for buyers and sellers to search for the most attractive rates. Simultaneously, PFTs’ function makes market-making more competitive and reduces dealer profitability as liquidity providers. The inside spread represents the price that buyers and sellers of liquidity face, and it also serves as the dealers’ profit incentive to make markets. As a narrower inside spread makes every transaction less profitable for market makers, traditional dealers, especially the smaller ones, should either find new revenue sources or exit the market.

During a financial crisis, such as post-COVID-19 turmoil in the financial market, such developments can lead to extremely high and volatile prices. The increased role of PTFs in the FX market could push smaller dealers to exit the market. Reduced profitability forces traditional FX dealers to adopt a new business model, but small dealers are most likely unable to make the necessary changes to remain competitive. Because a narrower inside spread reduces dealers’ compensation for providing liquidity, their willingness to carry exchange rate risk has correspondingly declined. Additionally, the post-GFC regulatory reforms reduced the balance sheet capacity of dealers by requiring more capital buffers. Scarce balance sheet space has increased the opportunity cost of dealing. 

Further, narrower inside spreads and the increased cost of dealing have encouraged FX dealers to offer prime brokerage services to leveraged institutional investors. The goal is to generate new revenue streams through fixed fees. PTFs have used prime brokerage to access the inter-dealer market and compete against small and medium dealers as liquidity providers. Order flow internalization is another strategy that large dealers have used to increase profitability. Rather than immediately hedge FX exposures in the inter-dealer market, dealers can wait for offsetting order flow from their client bases to balance their inventories—an efficient method to reduce fixed transaction costs. However, greater internalization reinforces the concentration of dealing with just a few large banks, as smaller dealers do not have the order flow volume to internalize a comparable percentage of trades.

Algorithmic traders could also intensify the riskiness of the market for FX derivatives. Compared to the small FX dealers they are replacing, algorithmic market makers face greater risk from hedging markets and exposure to volatile currencies. According to Mehrling’s FX dealer model, matched book dealers primarily use the forward market to hedge their positions in spot or swap markets and mitigate exchange rate risk. On the other hand, PTFs concentrate more on market-making activity in forward markets and use a diverse array of asset classes to hedge these exposures. Hedging across asset classes introduces more correlation risk—the likelihood of loss from a disparity between the estimated and actual correlation between two assets—than a traditional forward contract hedge. Since the provision of market liquidity relies on dealers’ ability to hedge their currency risk exposures, greater correlation risk in hedging markets is a systemic threat to the FX market’s smooth functioning. Additionally, PTFs supply more liquidity in EME currency markets, which have traditionally been illiquid and volatile compared to the major currencies. In combination with greater risk from hedging across asset classes, exposure to volatile currencies increases the probability of an adverse shock disrupting FX markets.

While correlation risk and exposure to volatile currencies has increased, new FX market makers lack the safety buffers that help traditional FX dealers mitigate shocks. Because the PTF market-making model utilizes high transaction speed to replace balance sheet capacity, there is a little buffer to absorb losses in an adverse exchange rate movement. Hence, algorithmic market makers are even more inclined than traditional dealers to pursue a balanced inventory. Since market liquidity, particularly during times of significant imbalances in supply and demand, hinges on market-makers’ willingness and ability to take inventory risks, a lack of risk tolerance among PTFs harms market robustness. Moreover, the algorithms that govern PTF market-making tend to withdraw from markets altogether after aggressively offloading their positions in the face of uncertainty. This destabilizing feature of algorithmic trading catalyzed the 2010 Flash Crash in the stock market. Although the Flash Crash only lasted for 30 minutes, flighty algorithms’ tendency to prematurely withdraw liquidity has the potential to spur more enduring market dislocations.

The weakening inter-dealer market will compound any dislocations that may occur as a result of liquidity withdrawal by PTFs. When changing fundamentals drive one-sided order flow, dealers will not internalize trades, and they will have to mitigate their exposure in the inter-dealer FX market. Increased dealer concentration may reduce market-making capacity during these periods of stress, as inventory risks become more challenging to redistribute in a sparser inter-dealer market. During crisis times, the absence of small and medium dealers will disrupt the price discovery process. If dealers cannot appropriately price and transfer risks amongst themselves, then impaired market liquidity will persist and affect deficit agents’ ability to meet their FX liabilities.

For many years, the FX market’s foundation has been built upon a competitive and deep inter-dealer market. The current phase of electronification and financialization is pressuring this long-standing system. The inter-dealer market is declining in volume due to dealer consolidation and competition from non-bank liquidity providers. Because the new market makers lack the balance sheet capacity and regulatory constraints of traditional FX dealers, their behavior in crisis times is less predictable. Moreover, the rise of non-bank market makers like PTFs has come at the expense of small and medium-sized FX dealers. Such a development undermines the economics of dealers’ function and reduces dealers’ ability to normalize the market should algorithmic traders withdraw liquidity. As the FX market is further financialized and trading shifts to more volatile EME currencies, risks must be appropriately priced and transferred. The new market makers must be up to the task.

What Can Explain the Tale of Two FX Swap Rates in the Offshore Dollar Funding Market?

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

By Elham Saeidinezhad

Mary Stigum once said, “Don’t fight the Fed!” There is perhaps no better advice that someone can give to an investor than to heed these words.

After the COVID-19 crisis, most aspects of the dollar funding market have shown some bizarre developments. In particular, the LIBOR-OIS spread, which used to be the primary measure of the cost of dollar funding globally, is losing its relevance. This spread has been sidelined by the strong bond between the rivals, namely CP/CD ratio and the FX swap basis. The problem is that such a switch, if proved to be premature, could create uncertainty, rather than stability, in the financial market. The COVID-19 crisis has already mystified the relationship between these two key dollar funding rates – CP/CD and FX swap basis- in at least two ways. First, even though they should logically track each other tightly according to the arbitrage conditions, they diverged markedly during the pandemic episode. Second, an unusual anomaly had emerged in the FX swap markets, when the market signaled a US dollar premium and discount simultaneously.  For the scholars of Money View, these so-called anomalies are a legitimate child of the modern international monetary system where agents are disciplined, or rewarded, based on their position in the hierarchy. This hierarchy is created by the hand of God, aka the Fed, whose impact on nearly all financial assets and the money market, in particular, is so unmistakable. In this monetary system, a Darwinian inequality, which is determined by how close a country is to the sole issuer of the US dollar, the Fed, is an inherent quality of the system.

Most of these developments ultimately have their roots in dislocations in the banking system. At the heart of the issue is that a decade after the GFC, the private US Banks are still pulling back from supplying offshore dollar funding. Banks’ reluctance to lend has widened the LIBOR-OIS spread and made the Eurodollar market less attractive. Money market funds are filling the void and becoming the leading providers of dollar funding globally. Consequently, the CP/CD ratio, which measures the cost of borrowing from money market funds, has replaced a bank-centric, LIBOR-OIS spread and has become one of the primary indicators of offshore dollar funding costs.

The market for offshore dollar funding is also facing displacements on the demand side. International investors, including non-US banks, appear to utilize the FX swap market as the primary source of raising dollar funding. Traditionally, the bank-centric market for Eurodollar deposits was the one-stop-shop for these investors. Such a switch has made the FX swap basis, or “the basis,” another significant thermometer for calculating the cost of global dollar funding. This piece shows that this shift of reliance from banks to market-based finance to obtain dollar funding has created odd trends in the dollar funding costs.

Further, in the world of market-based finance, channeling dollars to non-banks is not straightforward as unlike banks, non-banks are not allowed to transact directly with the central bank. Even though the Fed started such a direct relationship through Money Market Mutual Fund Liquidity Facility or MMLF, the pandemic revealed that there are attendant difficulties, both in principle and in practice. Banks’ defiance to be stable providers of the dollar funding has created such irregularities in this market and difficulties for the central bankers.

The first peculiar trend in the global dollar funding is that the FX swap basis has continuously remained non-zero after the pandemic, defying the arbitrage condition. The FX swap basis is the difference between the dollar interest rate in the money market and the implied dollar interest rate from the FX swap market where someone borrows dollars by pledging another currency collateral. Arbitrage suggests that any differences between these two rates should be short-lived as there is always an arbitrageur, usually a carry trader, inclined to borrow from the market that offers a low rate and lend in the other market, where the rate is high. The carry trader will earn a nearly risk-free spread in the process. A negative (positive) basis means that borrowing dollars through FX swaps is more expensive (cheaper) than borrowing in the dollar money market.

Even so, the most significant irregularity in the FX swap markets had emerged when the market signaled a US dollar premium and a discount simultaneously.  The key to deciphering this complexity is to carefully examine the two interest rates that anchor FX swap pricing. The first component of the FX swap basis reflects the cost of raising dollar funding directly from the banks. In the international monetary system, not all banks are created equal. For the US banks who have direct access to the Fed’s liquidity facilities and a few other high-powered non-US banks, whose national central banks have swap lines with the Fed, the borrowing cost is close to a risk-free interest rate (OIS). At the same time, other non-US banks who do not have any access to the central bank’s dollar liquidity facilities should borrow from the unsecured Eurodollar market, and pay a higher rate, called LIBOR.

As a result, for corporations that do not have credit lines with the banks that are at the top of the hierarchy, borrowing from the banking system might be more expensive than the FX swap market. For these countries, the US dollar trades at a discount in the FX swap market. Contrarily, when banks finance their dollar lending activities at a risk-free rate, the OIS rate, borrowing from banks might be less more expensive for the firms. In this case, the US dollar trades at a premium in the FX swap market. To sum up, how connected, or disconnected, a country’s banking system is to the sole issuer of the dollar, i.e., the Fed, partially determines whether the US dollar funding is cheaper in the money market or the FX swap market.

The other crucial interest rate that anchors FX swap pricing and is at the heart of this anomaly in the FX swap market is the “implied US dollar interest rate in the FX swap market.”  This implied rate, as the name suggests, reflects the cost of obtaining dollar funding indirectly. In this case, the firms initially issue non-bank domestic money market instruments, such as commercial papers (CP) or certificates of deposits (CDs), to raise national currency and convert the proceeds to the US dollar. Commercial paper (CP) is a form of short-term unsecured debt commonly issued by banks and non-financial corporations and primarily held by prime money market funds (MMFs). Similarly, certificates of deposit (CDs) are unsecured debt instruments issued by banks and largely held by non-bank investors, including prime MMFs. Both instruments are important sources of funding for international firms, including non-US banks. The economic justification of this approach highly depends on the active presence of Money Market Funds (MMFs), and their ability and willingness, to purchase short-term money market instruments, such as CPs or CDs.

To elaborate on this point, let’s use an example. Let us assume that a Japanese firm wants to raise $750 million. The first strategy is to borrow dollars directly from a Japanese bank that has access to the global dollar funding market. Another competing strategy is to raise this money by issuing yen-denominated commercial paper, and then use those yens as collateral, and swap them for fixed-rate dollars of the same term. The latter approach is only economically viable if there are prime MMFs that are able and willing, to purchase that CP, or CD, that are issued by that firm, at a desirable rate. It also depends on FX swap dealers’ ability and willingness to use their balance sheet to find a party wanting to do the flip side of this swap. If for any reason these prime MMFs decide to withdraw from the CP or CD market, which has been the case after the COVID-19 crisis, then the cost of choosing this strategy to raise dollar funding is unequivocally high for this Japanese firm. This implies that the disruptions in the CP/CD markets, caused by the inability of the MMFs to be the major buyer in these markets, echo globally via the FX swap market.

On the other hand, if prime MMFs continue to supply liquidity by purchasing CPs, raising dollar funding indirectly via the FX swap market becomes an economically attractive solution for our Japanese firm. This is especially true when the regional banks cannot finance their offshore dollar lending activities at the OIS rate and ask for higher rates. In this case, rather than directly going to a bank, a borrower might raise national currency by issuing CP and swap the national currency into fixed-rate dollars in the FX swap market. Quite the contrary, if issuing short-term money market instruments in the domestic financial market is expensive, due to the withdrawal of MMFs from this market, for instance, the investors in that particular region might find the banking system the only viable option to obtain dollar funding even when the bank rates are high. For such countries, the high cost of bank-lending, and the shortage of bank-centric dollar funding, is an essential threat to the monetary stability of the firms, and the domestic monetary system as a whole.

After the COVID-19 crisis, it is like a tug of war emerged between OIS rates and the LIBORs as to which type of interest rate that anchor FX swap pricing. Following the pandemic, the LIBOR-OIS spread widened significantly and this war was intensified. Money View declares the winner, even before the war ends, to be the bankers, and non-bankers, who have direct, or at least secure path to the Fed’s balance sheet. Marcy Stigum, in her seminal book, made it clear not to fight the Fed and emphasized the powerful role of the Federal Reserve in the monetary system! Time and time again, investors have learned that it is fruitless to ignore the Fed’s powerful influence. Yet, some authors put little effort into trying to gain a better understanding of this powerful institution. They see the Fed as too complex, secretive, and mysterious to be readily understood. This list does not include Money View scholars. In the Money View framework, the US banks that have access to the Fed’s balance sheet are at the highest layer of the private banking hierarchy. Following them are a few non-US banks that have indirect access to the Fed’s swap lines through their national central bank. For the rest of the world, having access to the world reserve currency only depends on the mercy of the Gods.

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.

What Exactly is the Function of the FX Market? A $6 Trillion Per Day Question

By Elham Saeidinezhad

“I am a hybrid. I do independent films and also do Hollywood films – I love them both.”  Spike Lee

According to the recent series of reports published by the Bank for International Settlements (BIS) on December 10th, 2019, trading in global Foreign Exchange (FX) markets reached $6.6 trillion per day in April 2019, up from $5.1 trillion in April 2016. To put the size of this market into perspective, the annual world GDP is around $80 trillion. The main instrument that dominates the FX trading is the FX swap.  On the contrary, the forward contracts form only a small portion of the whole market.  Capturing this difference in market share, standard finance theories tend to put more weight on the FX swaps. In doing so, they sometimes overlook the importance of forward contracts for the FX swaps market. However, once we consider the economics of dealers’ function in the FX market, the hybridity between these two instruments becomes essential. Most FX swaps are liquid and easily tradable only because of the dealers’ ability to manage their cash flows in the future by entering a forward contract with an FX forward dealer. The former aims at keeping a matched book and hedging against the FX risk, and the latter is a speculative dealer who takes on this risk for a fee. In other words, the ability and willingness of the FX swap dealer to make the market depend on the costs and easiness of entering a forward contract.

To understand the essential hybridity between these two instruments, let’s examine what connects these two markets. In an FX swap contract, two parties exchange two currencies today at the spot exchange rate and commit to reverse the exchange at some pre-agreed future date and price. The FX swap dealers– mostly large banks with branches in different countries-  are trading both sides of the market. Their presence in the market enable corporations to borrow at a currency that is cheaper and then swap the proceeds with the currency that they need. In this market, the dealer posts bid and ask prices for these FX swaps and rely on its access to the forward contracts and interbank market in Eurodollar deposits to hedge any mismatches in its balance sheets. FX forward contracts trade two currencies at a pre-agreed future date and price. The dealer who makes the market in the FX forward contract is a speculative dealer who takes the opposite position and provides the hedge for the FX swap dealer. The critical detail is that the speculative dealer provides the hedge since it expects to profit from this transaction. This profit comes from the expectation that the forward exchange rate is going to be higher than the expected spot rate. In other words, speculative dealer’s profit depends on the degree and the direction of the failure of uncovered interest parity (UIP). UIP states that the forward exchange rate will be equal to the expected spot rate since there will be an unexploited arbitrage opportunity otherwise.  The point of all this is to show that dealers will make a market in the FX swap markets only if they can depend on speculative dealers in the forward market to hedge their unmatched exposures.

Further, this hybridity between the FX swap and the related forward market highlights the role of the FX market as a wholesale funding market. The FX swap dealer sets the costs of financing in foreign currencies for the corporates. In doing so, the dealer earns the spread between bid-ask rates for the FX swap. Importantly, the FX swap dealer’s profit is determined by its access to the interbank Eurodollar funding, as well as its own hedging costs. The latter is settled by the FX forward dealer, who helps the FX swap dealer with cash flow management by taking a speculative position.  In doing so, the FX forward dealer acts as the private dealer of near last resort in the FX swap market and absorbs the imbalances in the FX swap markets on its balance sheets. The failure of the UIP is the source of expected profit for this speculative dealer. By fixing the costs of doing business for the FX swap dealer, the FX forward market affects the prices in the FX swap market. To sum up, once we consider the role of dealers in the FX market, we realize that FX forward and FX swap markets are entirely intertwined, and the dealers’ interactions in these markets ultimately determine the costs of foreign currency financings.
