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。     

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.     

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.     

Variations in effects of monetary policy on stock market returns in the past four decades

Stock prices are sensitive to monetary policy. However, the sensitivities are not stable over time. A drastic change in monetary policy can alter effects of monetary policy on stock returns. This study finds that stock prices can be affected by current changes, unexpected changes, or near-future changes in the funds/discount rates, due to different policy goals or targets in different periods. Specifically, this study provides empirical evidence that monetary policy influences the stock market in different ways in the 1960s, the 1970s, the Volcker and Greenspan periods.     

What Asset Prices Should Be Targeted by a Central Bank?

This paper investigates the monetary policy design for restoring equilibrium determinacy. Our interests are whether a central bank should respond to asset price fluctuations, and if so, what asset prices should be targeted. We show that a monetary policy response to the price of a productive tangible asset (capital price) is helpful for equilibrium determinacy, while that to the price of an intangible asset that reflects a firm's profit (share prices) is a source of equilibrium indeterminacy. This result comes from the two assets' prices moving in opposite directions in response to a permanent increase in inflation.     

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.     

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.     

Using private forecasts to estimate the effects of monetary policy

I develop a methodology that uses the forecasts of market participants and of policy makers to estimate the effects of monetary policy on output and inflation. My approach has advantages over the standard practice of fitting a vector autoregression to the data. I apply my methodology to data on output, interest rates and prices. I find that, even using the Federal Reserve Board's Greenbook forecasts to control for the policy maker's information set, prices rise initially in response to a monetary contraction. This finding undermines the standard justification for including an index of commodity prices in VARs.     

Flexible inflation targeting and financial stability: Is it enough to stabilize inflation and output?

We investigate empirically whether a central bank can promote financial stability by stabilizing inflation and output, and whether additional stabilization of asset prices and credit growth would enhance financial stability in particular. We employ an econometric model of the Norwegian economy to investigate the performance of simple interest rate rules that allow a response to asset prices and credit growth, in addition to inflation and output. We find that output stabilization tends to improve financial stability. Additional stabilization of house prices, equity prices and/or credit growth enhances stability in both inflation and output, but has mixed effects on financial stability. In general, financial stability as measured by e.g., asset price volatility improves, while financial stability measured by indicators that depend directly on interest rates deteriorates, mainly because of higher interest rate volatility owing to a more active monetary policy.     

资产价格波动形势下货币政策工具的宏观调控效应比较研究

本文通过构建VAR模型,识别资产价格对不同货币政策工具冲击的响应程度,发现各项贷款对于调控资产价格的效力最强,其次为货币供应量和利率政策。值得注意的是,贷款增长对于股价膨胀起到了重要支撑和推动作用,同时贷款少增对股价收缩效应也非常显著。本文强调,信贷数量调控对于平抑资产价格波动十分关键,选择性货币政策工具(Selective Credit Control)对于资产价格波动具有特殊调控效力。最后,本文提出了资产价格膨胀与资产价格收缩不同时期货币政策工具的搭配建议。     

What determines the stock market's reaction to monetary policy statements?

We find that information communicated through monetary policy statements has important business cycle dependent implications for stock prices. For example, during periods of economic expansion, stocks tend to respond negatively to announcements of higher rates ahead. In recessions, however, we find a strong positive reaction of stocks to seemingly similar signals of future monetary tightening. We provide evidence that the state dependence in the stock market's response is explained by information about the expected equity premium and future corporate cash flows contained in monetary policy statements. We also show state dependence in the average stock returns on days of scheduled FOMC meetings and in the impact of monetary policy statements on stock and bond return volatility.     

Eyes on the prize: How did the fed respond to the stock market?

Since the stock market boom of the 1990s, many have suggested the Federal Open Market Committee (FOMC) has adopted an unannounced policy goal of supporting equity values. This paper offers a new approach to disentangle the relationship between changes in equity values and monetary policy. Specifically, the paper distinguishes the FOMC's reaction to forecasts of traditional goal variables, which may depend on equity prices, from the FOMC's independent reaction to changes in equity prices. By using actual forward-looking variables examined by the FOMC before each action (the “Greenbook” forecasts), the authors find little evidence to support the proposition that the FOMC responds to stock values, except as filtered through a forecast of accepted monetary policy goal variables.     

Do central banks react to the stock market? The case of the Bundesbank

In this paper, we ask whether the Bundesbank, prior to the European Central Bank taking responsibility for monetary policy in 1999, reacted systematically to stock price movements. In contrast to the results for the US, our empirical findings show a generally weak relationship between German stock returns and short-term interest rates at the daily and the monthly frequency. The results are extremely robust to alternative model specifications. The evidence is inconsistent with the hypothesis of a systematic reaction of the Bundesbank to German stock prices. However, we do find that, as in the US, the Bundesbank may have reacted to the stock market crash of 1987 by loosening monetary policy.     

The open economy consequences of U.S. monetary policy

We consider the open economy consequences of U.S. monetary policy, extending the identification approach of Romer and Romer (2004) and adapting it for use with asset prices. Intended policy changes are orthogonalized against the economy’s expected future path, which captures any effects from open economy variables. Estimated from a set of bilateral VARs, the dynamic responses of the exchange rate, foreign interest rate, and foreign output are consistent with recent work that identifies U.S. policy via futures market changes and a priori impulse response bounds. We compare the two approaches, finding important commonalities. We also outline some advantages of our approach.     

Estimating monetary policy effects when interest rates are close to zero

Using a nonlinear structural VAR approach, we estimate the effects of exogenous monetary policy shocks in the presence of a zero lower bound constraint on nominal interest rates and examine the impact of such a constraint on the effectiveness of counter-cyclical monetary policies based on the data from Japan. We find that when interest rates are at zero, the output effect of exogenous shocks to monetary policy is cut in half if the central bank continues to target the interest rate. The conditional impulse response functions allow us to isolate the effect of monetary policy shocks operating through the interest rate channel when other possible channels of monetary transmission are present.     

The impact of monetary policy shocks on stock prices: Evidence from Canada and the United States

Using structural VAR models with short-run restrictions appropriate for Canada and the United States, we empirically examine whether trade and financial market openness matter for the impact on and transmission to stock prices of monetary policy shocks. We find that, in Canada, the immediate response of stock prices to a domestic contractionary monetary policy shock is small and the dynamic response is brief, whereas in the United States, the immediate response of stock prices to a similar shock is relatively large and the dynamic response is relatively prolonged. We find that these differences are largely driven by differences in financial market openness and hence different dynamic responses of monetary policy shocks between the two countries that we model in this paper.     

The real effects of financial stress in the Eurozone

This paper examines the real effects of financial stress in the Euro-zone, using two identification strategies based on a Bayesian Structural VAR and a Sign-Restriction VAR. As expansionary monetary policy has been blamed to have fuelled asset price bubble, it is important to assess the macroeconomic impact of both a financial stress shock and a monetary policy shock. We find that unexpected variation in financial stress conditions plays an important role in explaining output fluctuations and, therefore, demands an aggressive response by the monetary authority to stabilize output. This, in turn, indicates a preference shift from inflation targeting. We also show that a monetary policy contraction strongly deteriorates financial stress conditions. As a result, rapid credit growth due to a long period of low interest rates possibly contributed to an increase in asset prices and encouraged unsustainable demand growth as observed in the recent financial crisis.     

Monetary Policy and Stock Prices in an Open Economy

This paper studies monetary policy in a two-country model where agents can invest their wealth in both stock and bond markets. In our economy the foreign country hosts the only active equity market where also residents of the home country can trade stocks of listed foreign firms. We show that, in order to achieve price stability, the Central Banks in both countries should grant a dedicated response to movements in stock prices driven by relative productivity shocks. Determinacy of rational expectations equilibria and approximation of the Wicksellian interest rate policy by simple monetary policy rules are also investigated.     

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.     

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.
