Is the New Chapter for the Monetary Policy Framework Too Old To Succeed?

By Elham Saeidinezhad

Bagehot, “Money does not manage itself.”

In this year’s Jackson Hole meeting, the Fed announced a formal shift away from previously articulated longer-run inflation objective of 2 percent towards achieving inflation that averages 2 percent over time. The new accord aims at addressing the shortfalls of the low “natural rate” and persistently low inflation. More or less, all academic debates in that meeting were organized as arguments about the appropriate quantitative settings for a Taylor rule. The rule’s underlying idea is that the “market” tends to set the nominal interest rate equal to the natural rate plus expected inflation. The Fed’s role in this equation is to reduce or increase this market rate by changing the short-term federal funds rate whenever the inflation deviates from the target. The goal is to stabilize the long-run inflation. The Fed believes that the recent secular decline in natural rates relative to the historical average has constrained the power of the federal funds rate to achieve this mandate. The expectation is that the Fed’s decision to tolerate a temporary overshooting of the longer-run inflation to keep inflation and inflation expectations centered on 2 percent following periods when inflation has been persistently below 2 percent will address the framework’s constant failure and restore the magic of central banking. However, the ongoing issue with the Taylor rule-based monetary policy frameworks, including the recent one, is that they require the Fed to overlook the trends in the credit market, and only focus on the developments in the real economy, such as inflation or past inflation deviations, when setting the short-term interest rates. Rectifying such blind spots is what money view scholars were hoping for when the Fed announced its intention to review the monetary policy framework.

The logic behind the new framework, known as the average inflation targeting strategy, is that inflation undershooting makes achieving the target unlikely in the long run as it pushes the inflation expectations below the target. This being the case, when there is a long period of inflation undershooting the target, the Fed should act to undo the undershooting by overshooting the target for some time. The Fed sold forecast (or average) targeting to the public as a better way of accomplishing its mandate compared to the alternative strategies as the new framework makes the Fed more “history-dependent.” Translated into the money view language, however, the new inflation-targeting approach only delays the process of imposing excessive discipline in the money market when the consumer price index rises faster than the inflation target and providing excessive elasticity when prices are growing slower than the inflation target.

From the money view perspective, the idea that the interest rate should not consider private credit market trends will undermine central banking’s power in the future, as it has done in the past. The problem we face is not that the Fed failed to follow an appropriate version of Taylor rule. Rather, and most critically, these policies tend to abstract from the plumbing behind the wall, namely the payment system, by disregarding the credit market. Such a bias may have not been significant in the old days when the payment system was mostly a reserve-based system. In the old world, even though it was mostly involuntarily, the Fed used to manage the payment system through its daily interventions in the market for reserves. In the modern financial system, however, the payment system is a credit system, and its quality depends on the level of elasticity and discipline in the private credit market.

The long dominance of economics and finance views imply that modern policymakers have lost sight of the Fed’s historical mission to manage the balance between discipline and elasticity in the payment system. Instead of monitoring the balance between discipline and elasticity in the credit market, the modern Fed attempts to keep the bank rate of interest in line with an ideal “natural rate” of interest, introduced by Knut Wicksell. In Wicksellians’ world, in contrast to the money view, securing the continuous flow of credit in the economy through the payment system is not part of the Fed’s mandate. Instead, the Fed’s primary function is to ensure it does not choose a “money rate” of interest different from the “natural rate” of interest (profit rate capital). If lower, then the differential creates an incentive for new capital investment, and the new spending tends to cause inflation. If prices are rising, then the money rate is too low and should be increased; if prices are falling, then the money rate is too high and should be decreased. To sum up, Wicksellians do not consider private credit to be intrinsically unstable. Inflation, on the other hand, is viewed as the source of inherent instability. Further, they see no systemic relation between the payment system and the credit market as the payment system simply reflects the level of transactions in the real economy.

The clash between the standard economic view and money view is a battle between two different world views. Wicksell’s academic way of looking at the world had clear implications for monetary policy: set the money rate equal to the natural rate and then stand back and let markets work. Unfortunately, the natural rate is not observable, but the missed payments and higher costs of borrowing are. In the money view perspective, the Fed should use its alchemy to strike a balance between elasticity and discipline in the credit market to ensure a continuous payment system. The money view barometer to understand the credit market cycle is asset prices, another observable variable. Since the crash can occur in commodities, financial assets, and even real assets, the money view does not tell us which assets to watch. However, it emphasizes that the assets that are not supported by a dealer system (such as residential housing) are more vulnerable to changes in credit conditions. These assets are most likely to become overvalued on the upside and suffer the most extensive correction on the downside. A central bank that understands its role as setting interest rates to meet inflation targets tends to exacerbate this natural tendency toward instability. These policymakers could create unnaturally excessive discipline when credit condition is already tight or vice versa while looking for a natural rate of interest.

What Rules Inflation Targeting? A Time for Abandoning Taylor Rule

By Elham Saeidinezhad

“No matter how much suffering you went through, you never wanted to let go of those memories.”
― Haruki Murakami

Following the Global Financial Crisis (GFC), most central banks around the world are facing pressing challenges to reach the inflation target. Most recently, for example, Bank of Japan’s Governor Kuroda warned against threats to price stability and added more pointed language about a possible interest-rate cut. He promised to keep a close watch on the inflation target. As a result, the views are quietly shifting from targeting an inflation level to alternative approaches such as “average inflation targeting.” The more fundamental issue, however, is the fact that the target has never been sustainably achieved even though it has been in place since 2012. Against this backdrop, this is the right moment to steer the debate away from how to reach the 2 percent inflation target towards why we continuously fail to do so. Inflation targeting, enabled by Taylor Rule and based on rational expectations hypothesis, assumes that the public announcement of a medium-term target for inflation shapes the expectations of the future price level. However, once accounting for the financialization of modern economies, it becomes clear that it is not central banks’ abilities to form inflation expectations, but the extent of their influences on securities prices, that equip them to stabilize price levels. Nonetheless, central banks’ magic power to affect inflation might have mostly vanished.

To elaborate on this point, let’s start by defining inflation targeting and its premises. Inflation targeting is a monetary policy framework that aims at getting inflation to 2 percent and recognizes the readings above and below as universally undesirable. The structure that allows central banks to achieve the target is called “Taylor Rule,”- a principle that the monetary authorities should raise nominal interest rates by more than the increase in the inflation rate. The premise of this model is that central banks adjust the short-term interest rate and the quantity of reserves in the inter-bank lending market to influence components of the real economy, such as investment, trade balance, and consumption on residential housing through different channels. These channels are called “monetary transmission mechanisms” collectively and their ultimate goal is to achieve price and output stability.  This structure used to work in the old times when banks used reserves as a primary source of funding to lend to the real economy.

Today, arguably, we are living in a market liquidity system where most of the expenditures in the economy are financed in the capital market through a process known as “securitization.” In these circumstances, when the central bank changes the short-term interest rate and alters the spread between the overnight rate and the term rate, it effectively influences the incentives for dealers in both the money market and the capital market. The money market dealers establish the price of funding liquidity while the securities dealers determine the price of capital, including mortgage-backed securities (MBS). When the central bank increases the rates, it tightens the spread for money market dealers. In response, money market dealers increase the term interest rates and make it more expensive for securities dealers to finance their inventories. This process puts downward pressure on securities prices, including the price of MBS, which in turn increases the interest rates on the underlying loans such as mortgage and auto loans. Measuring the strength of these effects on the prices of the corresponding assets such as houses is notoriously difficult. To conclude, in modern economies, the interest rates on bank loans in most cases are not determined in the overnight domestic money market, where the central bank is the dominant player, but the global capital market. Thus, it is not the ability of monetary authorities to change inflation expectations, but the extent of their effect on securities prices that asset price stability. To retrieve their strength to influence the economy, central banks should start by fixing their understanding of the transmission structure of the monetary policy. Even so, central banks’ magic to affect the price level might have gone for the most part.

Discussion Questions:

  1. What is the main intellectual obstacle in fully understanding the extent of central banks’ power to influence price level?
  2. How are mortgage rates determined in advanced economies such as the U.S.?
  3. What is the main premise of Taylor Rule and Inflation Targeting?
