The discrete and differential impact of monetary policy

This study exploits a unique feature of the Australian monetary policy environment to determine whether economic recovery can be stimulated via central bank communications. This study finds that unexpected monetary policy announcements and communications have a significant and comparable impact on the value and volatility of the Australian foreign exchange market, suggesting that they can be used interchangeably to stimulate economic recovery. However, further analysis reveals that the state of the economy influences this impact. Specifically, during poor economic states, monetary policy actions speak louder than words, an adage that in this context provides actionable information for central bank regulators.     

Evidence of a bank lending channel in the UK

Using balance sheet data for a panel of UK listed firms, we find evidence of a bank lending channel of monetary transmission. A higher interest rate induces more bank lending to listed companies, but this effect diminishes if monetary policy becomes tight enough to impose severe constraints on bank loan lending. The dynamic behaviour of bank debt versus non-bank debt shows that the lending channel works through cutting back loan supplies to small, bank-dependent firms while restricting the bank’s ability to provide financial assistance to other firms. We see cross-sectional differences between bank-dependent and non-bank-dependent listed companies, and between listed and non-listed companies: Both can contribute to the size effect of investment. Small firms bear most of the reductions in bank loan supplies, and since they do not have many alternatives to bank finance, they suffer more from monetary tightening than big firms. This is consistent with inventory behavior. Furthermore, we have found that big, non-bank-dependent firms can benefit more from the bank–firm relationship than small, bank-dependent firms.     

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.     

The reaction of asset markets to Swiss National Bank communication

In this paper we analyze high-frequency movements in Swiss asset markets in reaction to real-time communication by the Swiss National Bank. Our analysis of central bank communication encompasses monetary policy announcements, speeches and interviews. We examine the reactions of the currency market, the bond market and the stock exchange. The evidence suggests that speeches and interviews, along with monetary policy announcements, engender a significant price reaction. This paper sheds light on the relevance of communications other than monetary policy announcements.     

Monetary Policy Implementation: Making Better and More Consistent Use of the Federal Reserve's Balance Sheet

Since December 2015, the Federal Reserve has operated a new “floor system” in which it brings about desired changes in its targeted federal funds rate by managing the interest rate it pays on bank reserves and other short‐term liabilities. The design of this new system reflects the tendency of Fed officials to view monetary policy as affecting the economy through Keynesian” interest rate channels. From this Keynesian perspective, policy actions that change the size of the balance sheet are seen as tools for influencing credit market conditions that operate in addition to and independently of the Fed's monetary policy stance. The alternative monetarist framework proposed by the author views monetary policy and its effects as operating through the interaction between money supply and demand. Use of this framework makes clear that, even under a floor system, monetary policy actions designed to affect the aggregate price level and the rate of inflation must be accompanied sooner or later by traditional open market operations that have implications for the size and composition of the Fed's balance sheet. Use of the monetarist framework also underscores the likelihood that the Fed, by paying interest on reserves, has unknowingly contributed to the restrictiveness of its own monetary policies since the financial crisis, a period during which inflation has run consistently below target. More generally, the monetarist framework downplays the importance of the zero lower interest rate bound and suggests that monetary policy could be conducted more effectively by adopting and adhering to a consistent, rule‐like manner during good times and bad.     

全球金融周期、美国货币政策与“三元悖论”

全球金融周期存在的背景下“三元悖论”是否依然成立充满争议。本文通过构建包含银行与金融摩擦的两国DSGE模型,为考察全球金融周期的形成提供了理论依据。美国货币政策通过资本流动传导到外围国金融市场,使外围国信贷利率、银行风险承担以及杠杆率与美国银行趋同,形成全球金融周期。金融渠道的传导速度快于实体经济渠道导致外围国国内经济周期与金融周期相背离,外围国想要稳定经济就不得不与美国保持同向的政策利率变化,货币政策独立性将不再存在。随着全球经济一体化进程加速,估值效应的作用越来越明显,浮动汇率制度并不能隔离全球金融周期的影响也无法保证货币政策的独立性。在资本账户开放的情况下,外围国金融市场越不发达,受全球金融周期的影响越大,货币政策越不独立。     

RESPONSE OF FINANCIAL MARKETS TO ANNOUNCEMENTS OF THE AUSTRALIAN CURRENT ACCOUNT BALANCE

This paper documents the response of exchange rates, interest rates and stock prices to monthly announcements of the Australian current account balance. Survey data on market participants' expectations and forecasts generated from ARIMA time series models are used to identify the unexpected component of the announcements. The study also controls for day-of-the-week effects that have been documented in the Australian equity market The results support the efficient market hypothesis and show a significant depreciation of the Australian dollar in foreign exchange markets and a significant rise in both short- and long-term interest rates to announcements of larger than expected current account deficits. The study was, however, unable to find evidence of a significant stock price response to the current account announcements.     

Does competition influence the bank lending channel in the euro area?

This paper examines how competition influences the bank lending channel in the euro area countries. Using a large panel of banks from 12 euro area countries for the period 2002–2010 we analyze the reaction of loan supply to monetary policy actions depending on the degree of bank competition. We find that the effect of monetary policy on bank lending is dependent on bank competition: the transmission of monetary policy via the bank lending channel is less pronounced for banks with extensive market power. Further investigation shows that banks with less market power were more sensitive to monetary policy only before the financial crisis. These results suggest that bank market power has a significant impact on the effectiveness of monetary policy. Therefore, wide variations in the level of bank market power may lead to asymmetric effects of the single monetary policy.     

地方政府债券置换对银行信贷及货币供给的影响

通过构建基于商业银行资产负债结构的地方债置换分析框架,研究表明,地方债置换将通过商业银行资产结构在贷款与债券之间的配置调整影响货币供给,它将使银行可贷资金增加,并导致贷款规模的变化,在贷款创造存款的信用放大机制下,引起货币供应量的变化,进而造成货币政策的扩张(收缩).贷款市场的供求弹性将决定地方债置换的扩张效应或收缩效应.在经济增长放缓、银行为弥补持有地方债收益下降、地方债纳入货币政策工具的抵押品和质押品范围的情况下,地方债置换具有货币政策扩张效应.为减少地方债对金融市场的冲击,央行需密切监测商业银行资金运用情况,提高货币政策操作的针对性,并加强同财政政策的协同配合.     

货币政策传导过程中的金融体系研究

金融体系在货币政策传导过程中起“中介”作用,货币渠道过程是通过金融市场从货币政策冲击到市场零售利率的价格传导过程,信贷渠道是通过商业银行从中央银行到商业银行的数量传导过程。完善我国金融体系有利于提高货币政策传导效果,同时也是市场经济体制改革的要求,我国中央银行实施货币政策时应该考虑区域金融差异的客观事实。     

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.     

Intraday volatility responses to monetary policy events

This paper explores the effects of US monetary policy events on intraday volatility in the US equity markets. We examine Federal Open Market Committee (FOMC) announcements as well as real-time changes in market expectations about future policy announcements and their impact on the intraday volatility dynamics of the S&P 500 index. The analysis shows elevated intraday volatility following FOMC announcements through the market close, with a spike at the time of the announcement. We then differentiate the volatility spike by modeling an asymmetric response based on the direction of the actual target rate change. Our results suggest that the size of the volatility spike is dependent on the direction of the rate change, with expansionary monetary policy actions having a larger spike than contractionary policy actions. The duration of these volatility spikes is relatively short-lived, with the spike dampening out within 15 minutes. A more lasting impact is, however, documented for real-time changes in market expectations where the volatility spike tends to persist for at least one hour.     

Bank risk and monetary policy

We find evidence of a bank lending channel operating in the euro area via bank risk. Financial innovation and the wider use of new ways of transferring credit risk have tended to diminish the informational content of standard bank balance sheet indicators. We show that bank risk conditions, as perceived by financial market investors, need to be considered, together with the other indicators (i.e., size, liquidity and capitalization), traditionally used in the bank lending channel literature to assess banks’ ability and willingness to supply new loans. Using a large sample of European banks, we find that banks characterized by lower expected default frequency are able to offer a larger amount of credit and to better insulate their loan supply from monetary policy changes.     

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.

Identifying the balance sheet and the lending channels of monetary transmission: A loan-level analysis

We make a novel attempt at comparing the strength of the lending and balance sheet channels of monetary transmission. To make this comparison, we use loan-level data to determine how borrower balance sheets and bank liquidity are related to bank lending decisions and how monetary policy can affect these relationships. The key innovation in this paper is the use of loan-level data. This enables us to measure the independent effects of the two channels and directly account for borrower balance sheets and lender liquidity instead of using proxies. Our results show that the balance sheet channel is the main mechanism through which monetary policy shocks are transmitted to the economy and that the lending channel does not play a significant role.     

International Transmission of U.S. Monetary Policy Shocks: Evidence from Stock Prices

This paper analyzes intraday changes in firm‐level equity prices around interest rate announcements to assess the transmission of U.S. monetary policy to the global economy. We document that foreign firms on average are roughly as sensitive to U.S. monetary policy as U.S. firms, although we also find considerable cross‐sectional variation across firms. In particular, foreign stocks in cyclically sensitive industries show stronger responses to interest rate surprises, consistent with a demand channel of policy transmission. In addition, transmission of U.S. policy appears to be stronger to economies with fixed exchange rates. Evidence for a credit channel is weaker.     

A model of unconventional monetary policy

We develop a quantitative monetary DSGE model with financial intermediaries that face endogenously determined balance sheet constraints. We then use the model to evaluate the effects of the central bank using unconventional monetary policy to combat a simulated financial crisis. We interpret unconventional monetary policy as expanding central bank credit intermediation to offset a disruption of private financial intermediation. Within our framework the central bank is less efficient than private intermediaries at making loans but it has the advantage of being able to elastically obtain funds by issuing riskless government debt. Unlike private intermediaries, it is not balance sheet constrained. During a crisis, the balance sheet constraints on private intermediaries tighten, raising the net benefits from central bank intermediation. These benefits may be substantial even if the zero lower bound constraint on the nominal interest rate is not binding. In the event this constraint is binding, though, these net benefits may be significantly enhanced.     

The Bank Lending Channel Revisited

A central proposition in research on the role of banks in the transmission mechanism is that monetary policy imparts a direct impact on deposits and that deposits act as the driving force of bank lending. This paper argues that the emphasis on policy‐induced changes in deposits is misplaced. A reformulation of the bank lending channel is proposed that works primarily through the impact of monetary policy on banks’ balance sheet strength and risk perception. Such a recasting implies, contrary to conventional wisdom, that greater reliance on market‐based funding enhances the importance of the channel.     

Spillovers of U.S. unconventional monetary policy to emerging markets: The role of capital flows

We employ a structural global VAR model to analyze whether U.S. unconventional monetary policy shocks, identified through changes in the central bank’s balance sheet, have an impact on financial and economic conditions in emerging market economies (EMEs). Moreover, we study whether international capital flows are an important channel of shock transmission. We find that an expansionary policy shock significantly increases portfolio flows from the U.S. to EMEs for almost two quarters, accompanied by a persistent movement in real and financial variables in recipient countries. Moreover, EMEs on average respond to the shock with an easing of their own monetary policy stance. The findings appear to be independent of heterogeneous country characteristics like the underlying exchange rate arrangement, the quality of institutions, or the degree of financial openness.
