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 shocks and stock returns: evidence from the British market

This paper examines the impact of anticipated and unanticipated interest rate changes on aggregate and sectoral stock returns in the United Kingdom. The monetary policy shock is generated from the change in the 3-month sterling LIBOR futures contract. Results from time-series and panel analysis indicate an important structural break in the relationship between stock returns and monetary policy shifts. Specifically, whereas before the credit crunch, the stock market response to both expected and unexpected interest rate changes is negative and significant; the relationship becomes positive during the credit crisis. The latter finding highlights the inability, so far, of monetary policymakers to reverse, via interest rate cuts, the negative trend observed in stock prices since the onset of the credit crisis.     

Monetary policy effects in times of negative interest rates: What do bank stock prices tell us?

This paper investigates bank stock performance following different monetary policy actions in times of positive and negative interest rates. Controlling for the broader stock market, monetary policy announcements that cause an unanticipated downward shift in the yield curve and a flattening of the shorter-end of the yield curve are found to persistently reduce bank stock prices once the interest rate environment is negative. Consistent with the deposits channel of monetary policy, the effects are larger and more persistent for banks that are relatively dependent on deposit funding. By contrast, a surprise movement in the slope of the longer-end of the yield curve does not impact bank stock prices in times of negative interest rates. Accounting data confirm that a parallel drop in the yield curve following a monetary policy decision in a negative interest rate environment hurts banks through shrinking deposit margins.     

Do monetary policy announcements affect stock prices in emerging market countries? The case of Thailand

We examine the effect of monetary policy announcements in Thailand, which is one of emerging market countries in Asia, on stock prices at the firm level. We find that the expected change, rather than the unexpected change, in interest rates affects stock prices. The stock price response to the interest rate announcement is asymmetric. For instance, the relation between interest rate surprises and stock prices is conditional on the direction of the interest rate change. In general, macroeconomic conditions and firm characteristics cannot explain the stock price reaction to the announcement. In addition, stock prices of firms in different industries appear to react heterogeneously to the interest rate announcement.     

Interest Rate Sensitivity, Asymmetry, and the Stock Returns of Financial Institutions

This paper attempts to reconcile the conflicting results reported in prior interest rate sensitivity studies that utilized the stock returns of financial institutions. By analyzing the interest rate elasticities during different interest rate cycles and adjusting for different monetary policy regimes, this paper suggests that sample period effects rather than methodological differences account for the conflicts presented in previous studies. More specifically, the empirical results indicate some asymmetrical interest rate sensitivities during various interest rate cycles. For example, the stock returns of savings and loan institutions were found to be more sensitive to falling interest rates. On the other hand, the stock returns of banks appeared to be more responsive to rising interest rates. Consequently, any attempt to employ models utilizing aggregated data either for policy making or to construct portfolio strategies will result in time aggregation bias and misguided decision making.     

Identifying the interdependence between US monetary policy and the stock market

We estimate the interdependence between US monetary policy and the S&P 500 using structural vector autoregressive (VAR) methodology. A solution is proposed to the simultaneity problem of identifying monetary and stock price shocks by using a combination of short-run and long-run restrictions that maintains the qualitative properties of a monetary policy shock found in the established literature [Christiano, L.J., Eichenbaum, M., Evans, C.L., 1999. Monetary policy shocks: what have we learned and to what end? In: Taylor, J.B., Woodford, M. (Eds.), Handbook of Macroeconomics, vol. 1A. Elsevier, New York, pp. 65-148]. We find great interdependence between the interest rate setting and real stock prices. Real stock prices immediately fall by seven to nine percent due to a monetary policy shock that raises the federal funds rate by 100 basis points. A stock price shock increasing real stock prices by one percent leads to an increase in the interest rate of close to 4 basis points.

The euro area stock market channel: Does one size fit all?

This paper analyzes the first part of the stock market channel of monetary policy in the euro area. We find heterogeneous reactions of euro area stock markets to unexpected ECB’s interest rate decisions. Splitting all markets into two groups, covering the stock markets reacting significantly to monetary policy shocks and the ones which do not, each sub-group reveals a higher degree of homogeneity. Interestingly, the markets, which react significantly to unexpected interest rate decisions are the markets with the highest stock market capitalization. In general, we find ECB’s decisions to be well anticipated by stock markets.     

美联储货币政策对我国资产价格的影响

本文利用事件研究法考察了美联储货币政策对我国资产价格的影响。研究发现美联储货币政策会显著影响我国资产价格,美联储加息会降低我国债券和股票回报,降息则会提高债券和股票回报。将美联储货币政策进行细分后发现,预期到的货币政策调整对债券市场和股票市场的回报都有显著影响,而未预期到的货币政策调整和前瞻性指引只影响债券市场。进一步的研究表明,未预期到的美联储货币政策调整和前瞻性指引还会加剧我国金融市场的波动率。本文的研究结论为美联储货币政策对我国经济金融的影响提供了新的证据,对于投资者提高投资收益、降低投资风险以及货币当局完善我国货币政策调控和维护我国金融市场稳定具有重要意义。     

International expected real interest rates: New tests of the parity hypothesis and U.S. fiscal policy effects

This paper investigates the links among expected real interest rates across countries and also those between international expected real interest rates and U.S. fiscal policy. We analyze the cross-sectional mean of international ex-post real interest rates as an estimator for the mean international expected real interest rate. Our results strongly reject the international expected real interest rate parity hypothesis; reveal that U.S. budget deficits have no independent effects on international real rates given the impact of U.S. government defense spending; and suggest that forces other than U.S. fiscal policy account for the post-1980 rise in international real rates.     

Equity market and the transmission channels of monetary policy: Before and after the zero lower bound

We examine the effectiveness of the interest rate channel and the credit channel of monetary policy before and after the zero lower bound (ZLB), using intraday stock returns. We construct a number of industry-specific and firm-specific indicators to capture the sensitivity of firms' demand to interest rates (interest rate channel) and firms' financial constraints (credit channel). We find that the transmission of monetary policy has shifted across both periods. Conventional monetary policy works through both the neoclassical interest rate channel and the credit channel, while unconventional policy is propagated primarily via the credit channel which became even more effective at the ZLB. Before the ZLB the transmission channels operate primarily through target rate shocks rather than forward guidance announcements, whereas both forward guidance and large scale asset purchases were equally important for the credit channel at the ZLB. We also find strong evidence that transmission channels are asymmetric depending on the state of the stock market (bull/bear, tighter/easier credit conditions, high/low volatility), and the type of policy surprises (positive/negative). Our findings are robust with respect to a number of model extensions and alternative specifications.     

Sensitivity of the bank stock returns distribution to changes in the level and volatility of interest rate: A GARCH-M model

The objective of this paper is to employ the generalized autoregressive conditionally heteroskedastic in the mean (GARCH-M) methodology to investigate the effect of interest rate and its volatility on the bank stock return generation process. This framework discards the restrictive assumptions of linearity, independence, and constant conditional variance in modeling bank stock returns. The model presented here allows for shifts in the volatility equation in response to the changes in monetary policy regime in 1979 and 1982 to be estimated. ARCH, GARCH, and volatility feed back effects are found to be significant. Interest rate and interest rate volatility are found to directly impact the first and the second moments of the bank stock returns distribution, respectively. The latter also affects the risk premia indirectly. The degree of persistence in shocks is substantial for all the three bank portfolios and sensitive to the nature of the bank portfolio and the prevailing monetary policy regime.     

The reaction of international stock markets to Federal Reserve policy

This paper investigates how changes in Federal Reserve policy impact international stock returns, with the three objectives of measuring the reaction of international stock markets, understanding the transmission channels of that reaction, and explaining the economic sources of that reaction. We find that unanticipated Federal Reserve policy actions exert a significant and robust influence on international stock prices. However, the influence of unanticipated monetary policy actions is not strong enough to change the correlation structure of international equity returns. We also find that international stock return co-movements play an important role in the transmission of monetary policy. Finally, the variance decomposition analysis indicates that the effects of monetary policy surprises on future excess returns or dividend returns account for the largest portion of the equity price response.

The impact of monetary policy decisions on stock returns: Evidence from Thailand

Although numerous studies have examined the effect of monetary policy on stock prices, empirical research in the international setting remains relatively scant. Therefore, this topic is reexamined in the context of Thailand. In a sample of 50 repurchase rate announcements of the Bank of Thailand during 2003–2009, our regression results suggest that the raw change in the repurchase rate has a negative effect on stock returns at the market level, which is inconsistent with the literature. Contrary to the results of numerous studies, we find that at the market level the expected change in the repurchase rate has a negative effect on stock returns and the unexpected change in the repurchase rate exhibits no effect on stock returns. However, the effect of the unexpected change in the repurchase rate on stock returns is evident at the firm level. Our findings also suggest that the stock market's response to the repurchase rate change is asymmetric. The unexpected change in the repurchase rate that is considered as good news has a negative effect on stock returns. Overall, the evidence lends support to the notion that the monetary policy announcements have a significant effect on stock prices and further adds to the debate on whether the creditability of the monetary authority may contribute to the stock market's response to the monetary policy actions.     

The Empirics of International Monetary Transmission: Identification and the Impossible Trinity

The transmission of monetary policy across borders is central to many open economy models. Research has tried to evaluate the “impossible trinity” through estimating international interest rate linkages under alternative exchange rate regimes using realized base country interest rates. Such interest rates include anticipated and endogenous elements, which need not propagate internationally. We compare international interest rate responses under pegged and non‐pegged regimes to identified, unanticipated, and exogenous U.S. interest rate changes and realized U.S. interest rate changes. We find important differences in estimated transmission from the two sets of measures—identified interest rate changes demonstrate a greater concordance with the impossible trinity than realized rate changes.     

我国货币政策对股票市场非对称影响的实证研究——基于马尔可夫区制转换VAR模型

本文基于1997年1月至2012年4月的数据,使用三区制滞后两阶的MS（3）-VAR（2）模型,对三种区制下货币政策对股票市场的影响进行分析。研究发现,在不同状态下,货币政策变量的变动对上址综指收益的影响在时间、方向和效果上是非对称的。在高收益、低波动状态与低亏损、低波动状态下,利率的变动对股票市场并不存在显著的影响;在高亏损、高波动状态下,利率的变动滞后一期对股票市场有较小的正向影响,但滞后二期时存在较大的负向影响。货币供应量变动对股票市场的影响在高亏损、高波动行情时比在高收益、低波动和低亏损、低波动行情时更加显著。总体来看,利率和货币供应量对股票市场的影响任高亏损、高波动行情下是显著的。     

我国货币政策变动对股票市场短期调控效应的实证分析

货币政策变动会对股市造成冲击。本文利用GARCH模型,运用事件研究方法研究利率、存款准备金率调整对股票市场的短期影响。通过实证分析,表明货币政策调整会对股票收益产生影响,但每次政策调整宣告对股票市场的影响程度、作用时间甚至影响方向都有所不同。这种即期影响取决于调整时经济运行的总体状况、股指相对位置、股市盘整的时间等影响因素,同时也取决于市场对政策调整的预期。     

Interest rate smoothing and price level trend-stationarity

This paper discusses the definition and mechanics of central bank interest rate smoothing under rational expectations. A tension arising between interest rate smoothing and macroeconomic stabilization objectives induces non-trend-stationary price level and money stock behavior. The paper thereby helps explain why such nominal non-stationarities are widely observed. Further implications are drawn for base drift, distribution of real returns on long-term fixed-rate nominal debt, and operating characteristics of interest rate pegs and policy instruments.
