On Monetary Policy and Stock Market Anomalies

This study utilizes a macro‐based VAR framework to investigate whether stock portfolios formed on the basis of their value, size and past performance characteristics are affected in a different manner by unexpected US monetary policy actions during the period 1967–2007. Full sample results show that value, small capitalization and past loser stocks are more exposed to monetary policy shocks compared with growth, big capitalization and past winner stocks. Sub‐sample analysis, motivated by variation in the realized premia and parameter instability, reveals that the impact of monetary policy shocks on these portfolios is significant and pronounced only during the pre‐1983 period.     

Financial constraints and stock returns

We test whether the impact of financial constraints on firmvalue is observable in stock returns. We form portfolios offirms based on observable characteristics related to financialconstraints and test for common variation in stock returns.Financially constrained firms' stock returns move together overtime, suggesting that constrained firms are subject to commonshocks. Constrained firms have low average stock returns inour 1968-1997 sample of growing manufacturing firms. We findno evidence that the relative performance of constrained firmsreflects monetary policy, credit conditions, or business cycles.     

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。     

作为货币政策调控目标的货币供应量和信贷规模

货币政策一般认为,作为金融数量指标的货币供应量在货币政策调控中占据着核心地位,而排斥另一重要金融数量指标——信贷规模的作用。本研究试图利用我国自1998年以来的经济金融数据,通过计量方法,比较货币供应量、信贷规模作为核心金融指标的适用性,发现:(1)信贷规模和货币供应量各自在不同意义上都是最稳定的,并且,各自与经济活动之间的关系一样规则而稳定,没有证据表明何者更具优势;(2)在同时引入货币供应量和信贷规模时,大大提高了对实体经济的解释能力;(3)货币供应量的变化依存于信贷规模的变化,表明信贷规模在我国经济金融中占据一定地位。这些结论对于理解我国货币政策传导机制是有意义的,表明政策调控时,应同时关注货币供应量和信贷规模这两个指标。     

The effect of monetary policy on real estate price growth in China

Using quarterly data from 1998:Q1 to 2009:Q4 and monthly data from July 2005 to February 2010, this paper examines the impact of key monetary policy variables, including long-term benchmark bank loan rate, money supply growth, and mortgage credit policy indicator, on the real estate price growth dynamics in China. Empirical results consistently demonstrate that expansionary monetary policy tends to accelerate the subsequent home price growth, while restrictive monetary policy tends to decelerate the subsequent home price growth. These results suggest that Chinese monetary policy actions are the key driving forces behind the change of real estate price growth in China. We also show that hot money flow does not have a significant impact on the change of home price growth after controlling for the money supply growth. Finally, a bullish stock market tends to accelerate subsequent home price growth.

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.     

新常态下中国货币政策的宏观经济效应研究 ——基于不同中介目标的实证检验

以中国2003-2020年的季度宏观经济数据为样本,通过构建时变系数向量自回归模型分析银行间同业拆借利率、M2、信贷规模、社会融资规模四项货币政策中介目标对实际产出、通货膨胀、房地产市场以及股票市场的动态影响效应.结果表明:同业拆借利率对产出的影响呈增强趋势,M2、信贷以及社会融资规模等数量型货币政策对产出的影响效应更显著;信贷与社会融资规模对通货膨胀的影响效应较显著;同业拆借利率对房地产市场的短期影响效应较大;M2、信贷与社会融资规模对房地产与股票市场的长期影响效应较大.     

中国货币政策目标制的选择——基于开放经济体的实证

本文使用开放经济下的新凯恩斯模型实证分析了开放经济体中不同的货币政策目标制。结果表明,面对国内利率政策、技术、国外通货膨胀、国外产出和国外实际利率冲击时,由灵活通货膨胀目标、资本自由流动和完全浮动的汇率构成的货币政策目标体系能够有效吸收冲击,减缓经济波动。相比而言,严格通胀目标制无法有效吸收国内外冲击,所以我国在开放经济下选择货币政策目标时,并不一定要选择严格通货膨胀目标,可以选择一些灵活通货膨胀目标的政策框架。此外,能够有效吸收各种冲击的灵活通胀目标、资本自由流动和完全浮动汇率制组成的目标体系也为我国货币政策和汇率制度改革提供了方向。     

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.     

Macroeconomic cycles and the stock market’s reaction to monetary policy

This paper examines cyclical variation in the effect of Fed policy on the stock market. We find a much stronger response of stock returns to unexpected changes in the federal funds target rate in recession and in tight credit market conditions. Using firm-level data, we also show that firms that face financial constraints are more affected by monetary shocks in tight credit conditions than the relatively unconstrained firms. Overall, the results are consistent with the credit channel of monetary policy transmission.     

Deposit interest rate ceilings as credit supply shifters: Bank level evidence on the effects of Regulation Q

How did deposit interest rate ceilings, an important feature of the U.S. regulatory regime until the mid-1980s, affect individual banks’ lending and the transmission of monetary policy to credit? I estimate the effect of deposit rate ceilings inscribed in Regulation Q on commercial banks’ credit growth using a historical bank level data set starting in 1959. Banks’ credit growth contracted sharply when legally fixed deposit rate ceilings were binding. Interaction terms with monetary policy suggest that the policy impact on bank level credit growth was non-linear and significantly larger when rate ceilings were in place. Bank size and capitalization mitigate these effects. At the bank level, short-term interest rates exceeding the legally fixed deposit rate ceilings identify policy induced credit supply shifts that disappeared with deposit rate deregulation and thus weakened the bank lending channel substantially since the early 1980s.     

Monetary policy and stock returns: Financing constraints and asymmetries in bull and bear markets

We examine asymmetries in the impact of monetary policy surprises on stock returns between bull and bear markets in the period 1994 to 2005. We ask how these impacts respond to the relative ability of firms to obtain external finance. We find that the impact of a surprise monetary policy in a bear market is large, negative, and statistically significant, and this holds across size decile portfolios. The impact of a surprise policy action in a bear market for most industries is significantly greater than the impact of surprise monetary policy in a bull market. Controlling for the capacity for external finance, stock returns of firms in bear states respond more than firms in bull states. Capacity for external finance is more important in a bear market, as it partially mitigates the larger impact of monetary policy in a bear market.     

Nonlinear relationship between monetary policy and stock returns: Evidence from the U.S.

This paper studies the relationship between monetary policy and stock market return in the U.S. using nonlinear econometric models. It first employs a univariate Markov-switching model on each of the three stock indices and three monetary policy variables, displaying significant regime-switching patterns and common movements. This paper then uses a Markov-switching dynamic bi-factor model to simultaneously extract two latent common factors from stock indices and monetary policy variables to represent monetary policy changes and stock market movements separately. The smoothed probabilities of regimes demonstrate that expansionary monetary policy regimes follow economic recessions, but bear stock markets usually occur before economic recessions. The maximum likelihood estimation results show that expansionary monetary policy such as a decrease in the federal funds rate raises stock returns, but stock returns don't directly influence monetary policy decision.     

An intertemporal capital asset pricing model with bank credit growth as a state variable

An ICAPM which includes bank credit growth as a state variable explains 94% of the cross-sectional variation in the average returns on the 25 Fama–French portfolios. We find compelling evidence that bank credit growth is priced in the cross-section of expected stock returns, even after controlling for well-documented asset pricing factors. These results are robust to the inclusion of industry portfolios in the set of test assets. They are also robust to the addition of firm characteristics and lagged instruments in the factor model. Bank credit growth is important because of its ability to predict business cycle variables as well as future labor income growth. These findings underscore the relevance of bank credit growth in stock pricing.     

Credit frictions and the comovement between durable and non-durable consumption

Frictions in lending between households have been proposed as a solution to the difficulties new-Keynesian models have in predicting a decline in both durable and non-durable consumption following a monetary tightening. By revisiting a standard new-Keynesian framework with collateral constraints, it is shown that the presence of such credit frictions in fact makes it more difficult to generate the joint decline. The intuitive reasons behind this result are provided, which should be helpful in developing models that are more successful in generating a positive comovement between durables and non-durables.     

Banks’ lending behavior and monetary policy: evidence from Sweden

The main purpose of this paper is to investigate the aggregate data about bank loans which may hide significant information about the monetary transmission mechanism. This study, by disaggregating bank loans data and using the relevant interest rates in Sweden, investigates the behaviour of banks after a monetary policy tightening. By using an unrestricted VAR model and impulse response analysis, our results show that a shock on the policy rate affects the main components of the banks’ loan portfolios differently. Initially, banks do not reduce lending to firms and households and they present a sluggish reaction concerning the relevant interest rates. On the contrary, they reduce lending to mortgage credit institutions significantly since real estate lending can be considered as a risky long-term investment. Moreover mortgage credit institutions reduce lending for housing purposes to non-bank public. This reduction is mainly driven by flexible rate loans and loans secured on tenant owned apartments. Consequently, theses actions have a significant effect on real economic activity, by amplifying the initial shock from the tightening monetary policy. The latter result provides evidence of the bank lending channel in Sweden working via mortgage lending and could be very important for policy makers.

Stock market reaction to fed funds rate surprises: State dependence and the financial crisis

This paper examines the response of US stock returns to Federal Funds rate (FFR) surprises between 1989 and 2012, focusing on the impact of the recent financial crisis. We find that outside the crisis period, stock prices increased as a response to unexpected FFR cuts. State dependence is identified with stocks exhibiting larger increases when interest rate easing coincided with recessions, bear markets, and tightening credit conditions. However, an important structural shift occurred during the crisis, changing the stocks’ response to FFR shocks and the nature of state dependence. Throughout the crisis period, stocks did not react positively to unexpected FFR cuts, which were interpreted as signals of worsening future economic conditions. This triggered a rebalancing of investment portfolios away from falling equities and towards safe-haven assets. Our results highlight the severity of the crisis and the ineffectiveness of conventional monetary policy close to the zero lower bound.     

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.
