International spillover effects of unconventional monetary policies of major central banks

This study examines the effects of unconventional monetary policies (UMPs) by the major central banks, namely the Bank of England (BOE), Bank of Japan (BOJ), European Central Bank (ECB) and the Federal Reserve (Fed), on the international financial markets, taking global spillovers and monetary policy interaction into account. To this end, we applied the Global Vector Autoregressive (GVAR) model to 35 countries/economies and one region for the period from March 2009 to July 2019. In addition, we accommodated the smooth transition to the GVAR to consider possible structural changes in the effects of UMPs and monetary policy interaction. Our results indicate the importance of capturing structural changes, showing the remarkable difference between the beginning and end of the sample. For example, we found clear evidence of monetary policy coordination after the global financial crisis and less evidence of policy interaction in the recent period. Also, our results suggest that generally, the UMPs of the major central banks had stronger effects on both domestic and international bond markets in the earlier period. In contrast, the global equity markets responded more positively to the UMPs in the recent period, although there was no noticeable difference in the responses of domestic equity markets throughout the sample.     

Testing for intraday interdependence and volatility spillover among the euro, the pound and the Swiss franc markets

To examine intraday interdependence and volatility spillover among the euro, the pound and the Swiss franc, we employ the varying-correlation model of multivariate generalized autoregressive conditional heteroskedasticity. Our main findings are (1) return volatility in the euro spills into the pound and the Swiss franc; and (2) these markets are highly integrated with the euro, and the degree of interdependence is state-dependent: euro news has a simultaneous impact on the pound and the Swiss franc, and co-movements of these currencies and the euro become much higher in proportion to the arrival of news of the euro.     

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.     

The impact of economic news on bond prices: Evidence from the MTS platform

Although there is an extensive literature on the impact of macroeconomic announcements on asset prices, the bond market has received less attention than the foreign exchange and equity markets, even less if we consider the European market. This paper uses high-frequency intra-day data over a three-year period to investigate the impact of regularly scheduled macroeconomic news and monetary policy announcements on the returns of the Italian government bond market, the largest one in the Euro-zone. With respect to the previous papers, we use a much broader set of announcements, 68, and a relatively novel dataset (MTS). We find that 25 news have a significant impact on bond returns and that almost all announcements are incorporated into prices within 20 min from the release.     

The high-frequency response of exchange rates to monetary policy actions and statements

This paper investigates the impact of US monetary policy on the level and volatility of exchange rates using an event study with intraday data for five currencies (the US dollar exchange rate versus the euro, the Canadian dollar, the British pound, the Swiss franc, and the Japanese yen). I construct two indicators of news about monetary policy stemming separately from policy decisions and from balance of risk statements. Estimation results show that both policy decisions and communication have economically large and highly significant effects on the exchange rates, with the surprise component of statements accounting for most of the explainable variation in exchange rate returns in response to monetary policy. This paper also shows that exchange rates tend to absorb FOMC monetary surprises within 30-40 min from the announcement release.

The impacts of standard monetary and budgetary policies on liquidity and financial markets: International evidence from the credit freeze crisis

This paper evaluates the domestic and international impacts of lowering short-term interest rates and increasing budget spending on several indicators of liquidity, volatility, credit and economic activity. Data from the 2003–2011 period in the United States, the Euro zone and Canada were used to develop two SVAR models for assessing the national effectiveness and the international spillovers of monetary and budgetary policies during the credit freeze crisis. While monetary policies caused a temporary decrease in volatility and increase in liquidity in North American stock markets, the shocks were mainly domestic and ineffective at generating liquidity in the banking sector. In contrast, government spending shocks had a positive impact on credit and consumption, especially in Europe and Canada. Moreover, budgetary policies also had a positive international spillover effect on consumption and credit, especially for smaller economies such as Canada.     

Central bank announcements of asset purchases and the impact on global financial and commodity markets

We present evidence on the effects of large-scale asset purchases by the Federal Reserve and the Bank of England since 2008. We show that announcements about these purchases led to lower long-term interest rates and depreciations of the U.S. dollar and the British pound on announcement days, while commodity prices generally declined despite this more stimulative financial environment. We suggest that LSAP announcements likely involved signaling effects about future growth that led investors to downgrade their U.S. growth forecasts lowering long-term US yields, depreciating the value of the U.S. dollar, and triggering a decline in commodity prices. Moreover, our analysis illustrates the importance of controlling for market expectations when assessing these effects. We find that positive U.S. monetary surprises led to declines in commodity prices, even as long-term interest rates fell and the U.S. dollar depreciated. In contrast, on days of negative U.S. monetary surprises, i.e. when markets evidently believed that monetary policy was less stimulatory than expected, long-term yields, the value of the dollar, and commodity prices all tended to increase.     

Monetary policy surprises and international bond markets

We examine the impact and spillover effects of monetary policy surprises on international bond returns. Within the framework of Campbell and Ammer (1993), we decompose international bond returns into news regarding future returns, real interest rates and future inflation for Germany, the U.K. and the U.S. We examine how excess bond returns in these three countries are affected by surprise changes in monetary policy in each country. Our measure of the unanticipated element of monetary policy is based on futures markets rather than the more traditional vector autoregression. Our results indicate that excess bond returns primarily react to domestic as compared to foreign monetary policy surprises. We also find there is a strong divergence between the effects of domestic monetary policy on excess bond returns in Germany relative to the U.K. A surprise monetary tightening in Germany (U.K.) leads to a rise (fall) in the excess holding period return. We trace this effect to news about lower (higher) inflation expectations and could be potentially rationalized by differences in the credibility of the monetary policy authority in each country.     

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.     

Capital inflows and asset prices: Evidence from emerging Asia

The withdrawal of foreign capital from emerging countries at the height of the recent financial crisis and its quick return sparked a debate about the impact of capital flow surges on asset markets. This paper addresses the response of property prices to an inflow of foreign capital. For that purpose we estimate a panel VAR on a set of Asian emerging market economies, for which the waves of inflows were particularly pronounced, and identify capital inflow shocks based on sign restrictions. Our results suggest that capital inflow shocks have a significant effect on the appreciation of house prices and equity prices. Capital inflow shocks account for – roughly – twice the portion of overall house price changes they explain in OECD countries. We also address cross-country differences in the house price responses to shocks, which are most likely due to differences in the monetary policy response to capital inflows.     

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.     

What are the effects of monetary policy on output? Results from an agnostic identification procedure

This paper proposes to estimate the effects of monetary policy shocks by a new agnostic method, imposing sign restrictions on the impulse responses of prices, nonborrowed reserves and the federal funds rate in response to a monetary policy shock. No restrictions are imposed on the response of real GDP to answer the key question in the title. I find that “contractionary” monetary policy shocks have no clear effect on real GDP, even though prices move only gradually in response to a monetary policy shock. Neutrality of monetary policy shocks is not inconsistent with the data.     

Reconsidering the role of money for output, prices and interest rates

New Keynesian models of monetary policy downplay the role of monetary aggregates, in the sense that the level of output, prices, and interest rates can be determined without knowledge of the quantity of money. This paper evaluates the empirical validity of this prediction by studying the effects of shocks to monetary aggregates using a vector autoregression (VAR). Shocks to monetary aggregates are identified by the restrictions suggested by New Keynesian monetary models. Contrary to the theoretical predictions, shocks to broad monetary aggregates have substantial and persistent effects on output, prices and interest rates.     

The impact of monetary policy on asset prices

Estimating the response of asset prices to changes in monetary policy is complicated by the endogeneity of policy decisions and the fact that both interest rates and asset prices react to numerous other variables. This paper develops a new estimator that is based on the heteroskedasticity that exists in high-frequency data. We show that the response of asset prices to changes in monetary policy can be identified based on the increase in the variance of policy shocks that occurs on days of FOMC meetings and of the Chairman's semi-annual monetary policy testimony to Congress. The identification approach employed requires a much weaker set of assumptions than needed under the “event-study” approach that is typically used in this context. The results indicate that an increase in short-term interest rates results in a decline in stock prices and in an upward shift in the yield curve that becomes smaller at longer maturities. The findings also suggest that the event-study estimates contain biases that make the estimated effects on stock prices appear too small and those on Treasury yields too large.     

House Price Booms,Current Account Deficits,and Low Interest Rates

Domestic factors, such as credit and preference shocks, can explain the negative correlation between house prices and the current account in the U.S. and several other countries before the recent crisis. These shocks, however, cannot account for the fall of world real interest rates observed in the data. Expansionary monetary policy shocks in the U.S., coupled with exchange rate pegs to the dollar in emerging economies, are crucial to understanding the evolution of the real interest rate. Yet, monetary policy factors play virtually no role for house prices and the current account.     

Credit Markets and the Propagation of Monetary Policy Shocks

This paper analyzes the propagation of monetary policy shocks through the creation of credit in an economy. Models of the monetary transmission mechanism typically feature responses that last for a few quarters contrary to what the empirical evidence suggests. To propagate the impact of monetary shocks over time, these models introduce adjustment costs by which agents find it optimal to change their decisions slowly. This paper presents another explanation that does not rely on any sort of adjustment costs or stickiness. In our economy, agents own assets and make occupational choices. Banks intermediate between agents demanding and supplying assets. Our interpretation is based on the way banks create credit and how the monetary authority affects the process of financial intermediation through its monetary policy. As the central bank lowers the interest rate by buying government bonds in exchange for reserves, high productive entrepreneurs are able to borrow more resources from low-productivity agents. We show that this movement of capital among agents sets in motion a response of the economy that resembles an expansionary phase of the cycle.     

Do the ECB and the fed really need to cooperate? Optimal monetary policy in a two-country world

A two-country model with monopolistic competition and price stickiness is employed to investigate the implications for macroeconomic stability and the welfare properties of three international policy arrangements: (a) cooperative, (b) non-cooperative and (c) monetary union. I characterize the conditions under which there is scope for policy cooperation and quantify the costs of non-cooperation and monetary union. The non-cooperative equilibrium may be suboptimal because of terms of trade spillover effects, while monetary union may be suboptimal because of the sluggishness of relative prices. Both the costs of policy competition and of a monetary union are sensitive to the values assumed for the intertemporal and international demand elasticity and the degree of openness of the economy. Independently of the calibration scenario adopted, the ECB has little to gain by coordinating with the Fed.     

Dynamic effects of idiosyncratic volatility and liquidity on corporate bond spreads

We study the dynamic impact of idiosyncratic volatility and bond liquidity on corporate bond spreads over time and empirically disentangle both effects. Using an extensive data set, we find that both idiosyncratic volatility and liquidity are critical mainly for the distress portfolios, i.e., low-rated and short-term bonds; for others only volatility matters. The effects of volatility and liquidity shocks on bond spreads were both exacerbated during the recent financial crisis. Liquidity shocks are quickly absorbed into bonds prices; however, volatility shocks are more persistent and have a long-term effect. Our results overall suggest significant differences between how volatility and liquidity dynamically impact bond spreads.     

The effectiveness of the ECB’s unconventional monetary policy: Comparative evidence from crisis and non-crisis Euro-area countries

During the European financial crisis, the European Central Bank implemented a series of unconventional monetary policy measures. We argue that these programs lowered the bond yield spreads of Euro-area countries. This hypothesis is tested using pooled OLS estimations and two different datasets: monetary policy event dummies and the purchase volumes of the Securities Markets Programme (SMP). Overall, we find significantly negative effects on bond yield spreads for both datasets, leading us to accept the hypothesis. While the OMT reduces the spreads of both crisis and non-crisis countries, LTROs and the lowering of the deposit rate to 0 percent are mainly effective in non-crisis countries. The SMP lowers the spreads of crisis countries, but it has the opposite effect on non-crisis countries. This converse effect is explained by the risk that increasingly accumulates on the ECB’s balance sheet through the SMP and that way constitutes a fiscal risk for non-crisis countries. The results are confirmed by pooled OLS estimations that measure the effect of unconventional monetary policy on central government debt.
