The Liquidity Effect in the Federal Funds Market: Evidence at the Monthly Frequency

In this paper, we argue that much of the research into the link between money and interest rates suffers from misspecification. The measure of money and the measure of interest rates are not always well matched. In examining the transmission of monetary policy, we show that using an appropriate measure of money, Federal Reserve balances, and the appropriate interest rate, the federal funds rate, a clear liquidity effect exists. Furthermore, we explain how a lack of a clear institutional understanding may have contributed to the finding of a "liquidity puzzle" in the past.     

The mechanics of a graceful exit: Interest on reserves and segmentation in the federal funds market

To combat the financial crisis that intensified in the fall of 2008, the Federal Reserve injected a substantial amount of liquidity into the banking system. The resulting increase in reserve balances exerted downward price pressure in the federal funds market, and the effective federal funds rate began to deviate from the target rate set by the Federal Open Market Committee. In response, the Federal Reserve revised its operational framework for implementing monetary policy and began to pay interest on reserve balances in an attempt to provide a floor for the federal funds rate. Nevertheless, following the policy change, the effective federal funds rate remained below not only the target but also the rate paid on reserve balances. We develop a model to explain this phenomenon and use data from the federal funds market to evaluate it empirically. In turn, we show how successful the Federal Reserve may be in raising the federal funds rate even in an environment with substantial reserve balances.     

Monetary policy implementation and the federal funds rate

This paper investigates how the implementation of monetary policy affects the dynamics and the volatility of the federal funds rate. Since the early 1980s, the most important changes in the Fed’s conduct of monetary policy refer to the role of the federal funds rate target and the reserve requirement system. We show that the improved communication and transparency regarding the federal funds rate target has significantly increased the Fed’s influence on the federal funds rate since 1994. By contrast, the declining role of required reserves in the US has contributed to higher federal funds rate volatility. Our results suggest that the introduction of remunerated required reserves will further enhance the controllability of the federal funds rate.     

The liquidity effect for open market operations

The liquidity effect is the negative relationship between the supply of federal funds and the overnight federal funds rate. Deviations of the federal funds rate from its target can be interpreted as demand innovations for federal funds. Permanent adjustments to demand are modeled as an unobserved component and estimated using the Kalman filter to identify liquidity effects. The demand-based approach for identifying the liquidity effect contrasts previous work which concentrates on errors forecasting the supply of federal funds. This paper finds a liquidity effect several times larger than that from previous studies, indicating the market for federal funds is less liquid than previously thought. The effect of a $1 billion increase in open market operations over a 1-week period is a decrease of the federal funds rate by about 12 basis points.     

U.S. monetary policy indicators and international stock returns: 1970-2001

It is documented in the literature that U.S. and many international stock returns series are sensitive to U.S. monetary policy. Using monthly data, this empirical study examines the short-term sensitivity of six international stock indices (the Standard & Poor 500 [S&P] Stock Index, the Morgan Stanley Capital International [MSCI] European Stock Index, the MSCI Pacific Stock Index, and three MSCI country stock indices: Germany, Japan, and the United Kingdom) to two major groups of U.S. monetary policy indicators. These two groups, which have been suggested by recent research to influence stock returns, are based on the U.S. discount rate and the federal funds rate. The first group focuses on two binary variables designed to indicate the stance in monetary policy. The second group of monetary indicators involves the federal funds rate and includes the average federal funds rate, the change in the federal funds rate, and the spread of the federal funds rate to 10-year Treasury note yield. Dividing the sample period (1970-2001) into three monetary operating regimes, we find that not all policy indicators influence international stock returns during all U.S. monetary operating periods or regimes. Our results imply that the operating procedure and/or target vehicle used by the Federal Reserve Board (Fed) influences the efficacy of the policy indicator. We suggest caution in using any monetary policy variable to explain and possibly forecast U.S. and international stock returns in all monetary conditions.     

Monetary Policy and Asset Prices: A Mechanism Design Approach

We investigate the effects of monetary policy on asset prices in economies where assets are traded periodically in bilateral meetings. The trading mechanism is designed to maximize social welfare taking as given the frictions in the environment and monetary policy. We show that asset price “bubbles” emerge in a constrained‐efficient monetary equilibrium only if liquidity is abundant and the first‐best allocation is implementable. In contrast, if liquidity is scarce, assets are priced at their fundamental value in any constrained‐efficient monetary equilibrium, in which case an increase in inflation has no effect on asset prices, but it reduces output and welfare.     

What are the effects of monetary policy on output? Results from an agnostic identification procedure

This paper proposes to estimate the effects of monetary policy shocks by a new agnostic method, imposing sign restrictions on the impulse responses of prices, nonborrowed reserves and the federal funds rate in response to a monetary policy shock. No restrictions are imposed on the response of real GDP to answer the key question in the title. I find that “contractionary” monetary policy shocks have no clear effect on real GDP, even though prices move only gradually in response to a monetary policy shock. Neutrality of monetary policy shocks is not inconsistent with the data.     

美联储利率承诺的宏观经济效应

作为金融危机后美联储非常规货币政策的重要手段之一,利率承诺对美国宏观经济变化的影响颇受关注。本文选取美国2001年1月至2011年8月的月度数据,以2008年12月为分界点,采用VAR模型实证检验了美联储非常规货币政策实施前后利率承诺政策对金融市场和实体经济的影响。研究结果表明:(1)零利率承诺缩短了金融市场对基准利率变动响应的时滞,但作用持续期明显缩短,其中股票市场和商业房地产市场的响应尤为明显;(2)零利率承诺政策有利于提升消费者信心,并抑制通货紧缩;(3)零利率承诺措施对实体经济的影响要大于对金融市场的影响。     

再析美国金融危机前的利率政策

全球金融危机与美国货币政策的变化密不可分,从低利率货币信贷扩张的流动性过剩到高利率的流动性紧缩,使宏观经济产生剧烈波动,前期低利率带来过剩的流动性,后期利率的提高造成巨量房地产泡沫的破灭。让美联储无视资产泡沫的原因是美联储货币政策一贯秉持的"泰勒规则"指导原则没有纳入资产价格因子,致使美联储货币政策调控失误。     

Monetary policy and distribution

A segmented markets model of monetary policy is constructed, in which a novel feature is goods market segmentation, and its relationship to conventional asset market segmentation. The implications of the model for the response of prices, interest rates, consumption, labor supply, and output to monetary policy are determined. As well, optimal monetary policy is studied, as are the costs of inflation. The model features persistent nonneutralities of money, relative price effects of increases in the money supply, persistent liquidity effects, and a negative Fisher effect from a money supply increase. A Friedman rule is in general suboptimal.     

Global asset prices and FOMC announcements

This paper analyzes the impact of U.S. monetary policy announcement surprises on foreign equity indexes, short- and long-term interest rates, and exchange rates in 49 countries. We use two proxies for monetary policy surprises: the surprise change to the current target federal funds rate (target surprise) and the revision to the expected path of future monetary policy (path surprise). We find that different asset classes respond to different components of the monetary policy surprises. Global equity indexes respond mainly to the target surprise; exchange rates and long-term interest rates respond mainly to the path surprise; and short-term interest rates respond to both surprises. On average, a hypothetical surprise 25-basis-point cut in the federal funds target rate is associated with about a 1 percent increase in foreign equity indexes and a 5 basis point decline in foreign short-term interest rates. A surprise 25-basis-point downward revision in the expected path of future policy is associated with about a ½ percent decline in the exchange value of the dollar against foreign currencies and 5 and 8 basis point declines in short- and long-term interest rates, respectively. We also find that asset prices’ responses to FOMC announcements vary greatly across countries, and that these cross-country variations in the response are related to a country’s exchange rate regime. Equity indexes and interest rates in countries with a less flexible exchange rate regime respond more to U.S. monetary policy surprises. In addition, the cross-country variation in the equity market response is strongly related to the percentage of each country’s equity market capitalization owned by U.S. investors. This result suggests that investors’ asset holdings may play a role in transmitting monetary policy surprises across countries.     

Changes in the Federal Reserve Communication Strategy: A Structural Investigation

This paper structurally investigates the changes in the Fed's communication strategy since the mid‐1990s through the lens of anticipated and unanticipated disturbances to a Taylor rule. The anticipated disturbances are identified using Treasury bond yield data in estimating a dynamic stochastic general equilibrium (DSGE) model with a term structure of interest rates. Our estimation results show that the Fed's decisions were unanticipated for market participants until 1999, but thereafter a larger portion of its future policy actions tended to be communicated in advance. We also find that the relative contribution of the anticipated monetary policy disturbances to macroeconomic fluctuations became larger after 1999. The bond yield data is indispensable to these results, since it contains crucial information on an expected future path of the federal funds rate.     

Dynamic Interactions among the Stock Market,Federal Funds Rate,Inflation, and Economic Activity

This paper examines the dynamic interactions among the equity market, economic activity, inflation, and monetary policy under three monetary policy regimes using bivariate and multivariate vector autoregressive cointegrating specifications. The bivariate results for the real stock returns‐inflation pair weakly support a negative correlation in the 1970s and 1980s. While the bivariate findings suggest a weak, negative relationship between real returns and the federal funds in the 1970s and 1980s, the multivariate findings strongly support short‐term linkages in the 1970s. There appears to be no consistent dynamic relationship between monetary policy and stock prices in that the relationship differs across monetary regimes.     

The Federal Reserve’s balance sheet and overnight interest rates: Empirical modeling of exit strategies

This paper provides a comprehensive study of the interplay between the Federal Reserve’s balance sheet and overnight interest rates. We model both the supply of and the demand for excess reserves. Treating outright securities holdings of the Federal Reserve as a policy tool, we estimate the effects of unconventional monetary policy on overnight funding rates. Further, we offer the first empirical assessment of the FOMC’s principles of the exit strategy. Assuming a path for removing monetary policy accommodation that is consistent with the FOMC’s exit principles, we project that the federal funds rate increases to 70 basis points by 2016, settling in a corridor bracketed by the discount rate and the interest rate on excess reserves, as excess reserves of depository institutions decline to near zero.     

Credit risk dynamics in response to changes in the federal funds target: The implication for firm short-term debt

The recent credit crisis has raised a number of interesting questions regarding the role of the Federal Reserve Bank and the effectiveness of its expected and unexpected interventions in financial markets, especially during the crisis, given its mandate. This paper reviews and evaluates the impact of expected and unexpected changes in the federal funds rate target on credit risk premia. The paper's main innovation is the use of an ACH-VAR (autoregressive conditional hazard VAR) model to generate the Fed's expected and unexpected monetary policy shocks which are then used to determine the effects of a Federal Reserve policy change on counterparty credit risk and more importantly short-term firm debt financing. The findings answer a longstanding question sought by researchers on the effect of policy makers' announcements on firm debt financing. The results clearly show that the Federal Reserve influences short-term debt financing through the credit channel for both expansionary and contractionary monetary policies. In particular, we find that the growth in counterparty risk appears less responsive to anticipated responses in the Fed funds rate that fail to materialize than to an unanticipated increase in the federal funds rate. Finally, we also document that the results appear to validate the Feds interventions in financial markets to stem counterparty risk and to make liquidity more readily available to firms.     

Analyzing Federal Reserve asset purchases: From whom does the Fed buy?

Asset purchases have become an important monetary policy tool of the Federal Reserve in recent years. To date, most studies of the Federal Reserve’s asset purchases have tried to measure the interest rate effects of the purchases, and several provide evidence that these purchases do have important effects on longer-term market interest rates. The theory of how asset purchases work, however, is less well developed. Some of the empirical studies point to “preferred habitat” models in which investors do not have the same objectives, and therefore prefer to hold different types and maturities of securities. To study this more closely, we exploit Flow of Funds data to assess the types of investors that are selling to the Federal Reserve and their portfolio adjustment after these sales, which could provide a view to the plausibility of preferred habitat models and the transmission of unconventional monetary policy across asset markets. We find that the Federal Reserve is ultimately buying from only a handful of investor types, primarily households (which includes hedge funds), with a different reaction to changes in Federal Reserve holdings of longer-term versus shorter-term assets. Although not evident for all investors, the key participants are shown to rebalance their portfolios toward more risky assets during this period. These results can be interpreted as supporting, at least in part, the preferred habit theory and the view that the monetary policy transmission is working across asset markets.     

Oman's monetary policy transmission process under the fixed peg: some empirical puzzles

This paper highlights that an open economy, like Oman, could often enjoy partial monetary policy independence despite operating with a fixed peg, which may appear as a clear violation of the ‘macroeconomic trilemma'. While explaining the country-specific factors that create the scope for partial monetary policy independence, the paper underscores that for meaningful use of this partial monetary policy independence to attain domestic goals of inflation and output, the transmission mechanism of monetary policy must work effectively. Empirical analyses presented in this paper for Oman, however, suggest the presence of not only the ‘interest rate puzzle’ but also the ‘IS puzzle’ and the ‘Phillips curve puzzle’, which together signal the presence of significant transmission weaknesses. The paper, thus, concludes that costs stemming from loss of any monetary policy independence because of the fixed peg may not be very significant for Oman, and hence, any alternative exchange rate regime cannot be viewed as appropriate just on the grounds that an alternative regime could deliver greater monetary policy independence.     

Using Survey Data to Correct the Bias in Policy Expectations Extracted from Fed Funds Futures

Many studies estimate risk premiums on federal funds futures to extract monetary policy expectations by assuming that average forecast errors of the expectations are zero or that survey forecasts are good proxies for the expectations. These assumptions, however, may fail due to an unanticipated declining trend in the federal funds rate and to survey respondents' strategic behavior. Consequently, the premiums estimated under these assumptions may be biased. We propose a new method to estimate the premiums and find that the premiums have been often negative since 2000, which is generally consistent with the negative betas observed in the 2000s.     

The Credit Channel at the Zero Lower Bound through the Lens of Equity Prices

This study examines the impact of unconventional monetary policies on the stock market when the short‐term nominal interest rate is stuck at the zero lower bound (ZLB). Unconventional monetary policies appear to have significant effects on stock prices and the effects differ across stocks. In agreement with existing credit channel theories, I find that firms subject to financial constraints react more strongly to unconventional monetary policy shocks [especially large‐scale asset purchases (LSAPs)] than do less constrained firms. These results imply that the credit channel is as important as the interest rate channel in the transmission of unconventional monetary policies at the ZLB.
