External shocks, U.S. monetary policy and macroeconomic fluctuations in emerging markets

Estimated structural VARs show that external shocks are an important source of macroeconomic fluctuations in emerging markets. Furthermore, U.S. monetary policy shocks affect interest rates and the exchange rate in a typical emerging market quickly and strongly. The price level and real output in a typical emerging market respond to U.S. monetary policy shocks by more than the price level and real output in the U.S. itself. These findings are consistent with the idea that “when the U.S. sneezes, emerging markets catch a cold.” At the same time, U.S. monetary policy shocks are not important for emerging markets relative to other kinds of external shocks.     

Hot Money and Quantitative Easing: The Spillover Effects of U.S. Monetary Policy on the Chinese Economy

We develop a factor‐augmented vector autoregression (FA‐VAR) model to estimate the effects that unanticipated changes in U.S. monetary policy and economic policy uncertainty have on the Chinese housing, equity, and loan markets. We find the decline in the U.S. policy rate since the Great Recession has led to a significant increase in Chinese housing investment. One possible reason for this effect is the substantial increase in the inflow of “hot money” into China. The responses of Chinese variables to U.S. shocks at the zero lower bound are different from those responses in normal times.     

Words that shake traders : The stock market's reaction to central bank communication in real time

This paper investigates the effects of Federal Reserve's decisions and statements on U.S. stock and volatility indices (Dow Jones Industrial Average, NASDAQ 100, S&P 500, and VIX) using a high-frequency event-study analysis. I find that both the surprise component of policy actions and official communication have statistically significant and economically relevant effects on equity indices, with statements having a much greater explanatory power of the reaction of stock prices to monetary policy. For instance, around 90% of the explainable variation in S&P 500 is due to the surprise component of Fed's statements. This paper also shows that equity indices tend to incorporate FOMC monetary surprises within 40 min from the announcement release. Finally, I find that these results are robust along several dimensions. In particular, I consider different estimators, such as the Generalized Empirical Likelihood, and I extend the sample to include the recent period of heightened financial stress. This sensitivity analysis corroborates that central bank communication about its future policy intentions is a key driver of stock returns.     

What Is the Importance of Monetary and Fiscal Shocks in Explaining U.S. Macroeconomic Fluctuations?

This paper analyzes the importance of monetary and fiscal policy shocks in explaining U.S. macroeconomic fluctuations, and establishes new stylized facts. The novelty of our empirical analysis is that we jointly consider both monetary and fiscal policy, whereas the existing literature only focuses on either one or the other. Our main findings are twofold: fiscal shocks are relatively more important in explaining medium cycle fluctuations whereas monetary policy shocks are relatively more important in explaining business cycle fluctuations, and failing to recognize that both monetary and fiscal policy simultaneously affect macroeconomic variables might incorrectly attribute the fluctuations to the wrong source.     

Capital Inflows and the U.S. Housing Boom

We estimate an open‐economy vector autoregressive (VAR) model to study the effect of capital‐inflow shocks on the U.S. housing market. We look at different external shocks that generate capital inflows to the U.S., in particular “saving‐glut” shocks and foreign monetary‐policy expansions. The shocks are identified with theoretically robust sign restrictions derived from an open‐economy dynamic stochastic general equilibrium (DSGE) model. Our findings suggest that capital inflows that result from “saving‐glut” shocks have a positive and persistent effect on real house prices and real residential investment.     

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.     

Dynamic relationships among equity flows,equity returns and dividends: Behavior of U.S. investors in China and India

This research examines the linkages among U.S. equity flows to China and India, their equity returns, and their fundamental variables. We find that positive shocks to U.S. equity flows to China and India elicit an insignificant response to returns. This finding provides evidence that U.S. institutional investors are not a destabilizing influence in these markets. However, positive innovations to dividends in both China and India have a negative impact on returns. We conjecture that the high potential growth rates in these markets make it preferable for companies to retain earnings rather than pay dividends. In India, shocks to dividend yields have a strong negative influence on U.S. equity flows. Our results validate the need to take into account fundamental variables when examining U.S. investor behavior in emerging equity markets.     

Cross-border spillover effects of unconventional monetary policies on Swiss asset prices

Unconventional monetary policies (UMPs) announced by the Federal Reserve, the European Central Bank, the Bank of England and the Bank of Japan exert important spillover effects on asset prices in Switzerland. Using a broad UMP event set and a long-term bond-futures based measure of market anticipation, we show that surprisingly expansionary UMPs lower Swiss government and corporate bond yields, induce the Swiss franc to appreciate, and dampen Swiss equity prices. Four extensions provide further insights. First, the estimated effects are strongest for announcements by the ECB. Second, the impact on government bonds is largest for bonds with residual maturities of 7–10 years. Third, the impact of foreign UMP shocks on exchange rates and Swiss bond yields is less pronounced after the introduction of the minimum rate of 1.20 Swiss franc per Euro by the Swiss National Bank on September 6, 2011, indicating that domestic monetary policy action partially affects the impact of external monetary shocks on domestic financial markets. Fourth, the sign of spillover effects differs for positive and negative UMP surprises, but their strength does not.     

Technology Shocks and Monetary Policy: Revisiting the Fed's Performance

Would the U.S. economy's dynamic response to permanent technology shocks have been different from the actual responses if monetary authorities' systematic response to these shocks had been optimal? To answer this question, we characterize the dynamic effects of permanent technology shocks and the way in which U.S. monetary authorities reacted to these shocks over the sample 1955(1)–2002(4) using a structural VAR. A sticky price–sticky wage model is developed and estimated to reproduce these responses. We then formally compare these responses with the outcome of the optimal monetary policy.     

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.     

Tracking U.S. inflation expectations with domestic and global indicators

Are foreign variables important for tracking U.S. inflation expectations? This paper estimates a reduced-form model that takes both domestic and global indicators of economic slack and inflationary pressures into account. Our main findings point towards the instability of the estimated parameters over the last four decades. In particular, global indicators appear to have played a statistically significant role in shaping forecasters’ expectations until the mid-1980s. By contrast, the U.S. monetary policy stance turns out to be relevant in the 1980s and 1990s. We relate this finding to the more aggressive monetary policy conduct implemented by the Fed since the end of the Volcker experiment.     

Funding conditions and insurance stock returns: Do insurance stocks really benefit from rising interest rate regimes?

We examine funding conditions and U.S. insurance company stock returns. Although constrained funding conditions, signaled by restrictive Federal Reserve monetary policy, correspond with increases in the future payouts of fixed‐income securities held by insurance firms and potentially provide value through the liability side of insurer balance sheets, they also decrease the values of securities currently held in insurer portfolios. Prior research finds that restrictive policy has a negative effect on equity returns in general. Our results suggest the negative impacts of constrained funding environments outweigh the potential positives, as insurance company stock returns are significantly lower during periods of constrained funding. This effect varies within a given funding state and also across insurer type. The effect is strongest during the first 3 months of a constrained funding environment and for life and health insurers—insurer types with longer portfolio durations. For property and liability (P&L) insurers, lower stock return performance only exists in the first 3 months of a constrained funding environment. In the subsequent months, P&L insurers actually have higher stock returns during constrained periods, consistent with their typically shorter duration asset portfolios, which are more quickly rolled over into new higher‐yielding securities.     

Household Debt Overhang and Transmission of Monetary Policy

We investigate how the level of household indebtedness affects the monetary transmission mechanism in the U.S. economy. Using state‐dependent local projection methods, we find that the effects of monetary policy are less powerful during periods of high household debt. In particular, the impact of monetary policy shocks is smaller on GDP, consumption, residential investment, house prices, and household debt during a high‐debt state. We then build a partial equilibrium model of borrower households with financial constraints to rationalize these facts. The model points to the weakening of the home equity loan channel as a possible reason for the decline in monetary policy effectiveness when initial debt levels are high.     

One Size Fits All? Monetary Policy and Asymmetric Household Debt Cycles in U.S. States

I investigate the nonlinear effects of monetary policy through differences in household debt across U.S. states. After constructing a novel indicator of inflation for the states, I compute state‐specific monetary policy stances as deviations from an aggregate Taylor rule. I find that the effectiveness of monetary policy is curtailed during periods of large household debt imbalances. Moreover, a common U.S. monetary policy does not fit all; it may have asymmetric effects on the economic performance across states, particularly at times of high dispersion in the household debt imbalances, as it may have been the case around the Great Recession.     

Risk,uncertainty and monetary policy

The VIX, the stock market option-based implied volatility, strongly co-moves with measures of the monetary policy stance. When decomposing the VIX into two components, a proxy for risk aversion and expected stock market volatility (“uncertainty”), we find that a lax monetary policy decreases both risk aversion and uncertainty, with the former effect being stronger. The result holds in a structural vector autoregressive framework, controlling for business cycle movements and using a variety of identification schemes for the vector autoregression in general and monetary policy shocks in particular. The effect of monetary policy on risk aversion is also apparent in regressions using high frequency data.     

Cross-sector comovements and policy impact in the COVID-19 stock market: A dynamic factor approach

This study investigates the remarkable comovements in U.S. equity returns during the COVID-19 pandemic. It constructs a dynamic factor model (DFM) to illuminate the sources of the comovements and their implications. Using the Markov Chain Monte Carlo (MCMC) estimation method, the study finds that the comovements had a weak daily oscillation pattern during the pandemic. With that pattern, the study also finds significant monetary policy effects on the equity returns of several key sectors. In addition, it estimates the impact of news shocks, including monetary policy news, fiscal stimulus news, and unemployment news, on cross-sector equity returns. For any given sector, the conventional and unconventional monetary policy news shocked the sector in opposite directions. Among the positive monetary news shocks, the strongest were from interest rate policy surprises. Conversely, fiscal stimulus news had the most substantial positive impact and triggered all sectors to rebound from the bear market at the end of March 2020. Furthermore, by applying Natural Language Processing (NLP) sentiment analysis, this study sheds light on the positive correlation between comovements and news sentiment.     

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.     

Capital Controls and the International Transmission of U.S. Money Shocks

We assess whether capital controls effectively insulate countries from U.S. monetary shocks, examining a large range of country experiences in a unified estimation framework. We estimate the effect of identified U.S. monetary shocks on the exchange rate and foreign country interest rates, and test whether countries with less open capital accounts exhibit systematically smaller responses. We find essentially no evidence of this. Other country factors such as the exchange rate regime or degree of dollarization explain more of the cross-country differences in responses. The significant differences in responses we do find are more pronounced at short horizons.     

U.S. Monetary Regimes and Optimal Monetary Policy in the Euro Area

Monetary policy in the United States has been documented to have switched from reacting weakly to inflation fluctuations during the 1970s, to fighting inflation aggressively from the early 1980s onward. In this paper, I analyze the impact of the U.S. monetary policy regime switches on the Eurozone. I construct a New Keynesian two‐country model where foreign (U.S.) monetary policy switches regimes over time. I estimate the model for the U.S. and the Euro Area using quarterly data and find that the United States has switched between those two regimes, in line with existing evidence. I show that foreign regime switches affect home (Eurozone) inflation and output volatility and their responses to shocks, substantially, as long as the home central bank commits to a time‐invariant interest rate rule reacting to domestic conditions only. Optimal policy in the home country instead requires that the home central bank reacts strongly to domestic producer‐price inflation and to international variables, such as imported goods relative prices. In fact, I show that currency misalignments and relative prices play a crucial role in the transmission of foreign monetary policy regime switches internationally. Interestingly, I show that only marginal gains arise for the Euro Area when the European Central Bank (ECB) adjusts its policy according to the monetary regime in the United States. Thus, a simple time‐invariant monetary policy rule with a strong reaction to Producer Price Index (PPI) inflation and relative prices is enough to counteract the effects of monetary policy switches in the United States.     

On cross-border bank credit and the U.S. financial crisis transmission to equity markets

This paper examines the role played by cross-border equity, bond and bank credit flows versus international trade in the transmission of the U.S. financial crisis to equity markets worldwide. We estimate vector autoregressive models with exogenous global factors using monthly data on 36 emerging and developed countries. The results from an eclectic methodology that includes causality tests, generalized impulse responses and forecast error variance decompositions indicate that the crisis is mostly transmitted through bank credit rather than portfolio flows and international trade. The results are robust to altering the exogenous versus endogenous vectors of variables, to measuring equity prices in U.S. dollars or local currency, to averaging the data across countries versus averaging the parameters from individual country estimation, and to redefining the start date of the crisis. The findings endorse the use of banking regulation and capital controls as part of the policy toolkit to limit financial vulnerability.
