One Monetary Policy and Eighteen Central Bankers: The European Monetary Policy as a Game of Strategic Delegation.

This paper employs a multi-country delegation model of a single monetary policy and argues that a decision making mechanism based on the median voter theorem is too restrictive for capturing important aspects of monetary policy in the European Monetary Union, particularly because intensity of preferences cannot play a role when only the median voter matters. Replacing the median voter mechanism by a less restrictive “weighted mean mechanism”, it is shown that strategic delegation leads to a single monetary policy set in accordance with the preferences of the most inflation-averse member state. This finding provides theoretical support for “The Twin Sister Hypothesis” and the perception of the European Central Bank implementing the policy of the Bundesbank rather than the policy of an average union-wide central bank.monetary policy; monetary union; median voter; strategic delegation

Official Japanese Intervention in the JPY/USD Exchange Rate Market: Is It Effective and Through Which Channel Does It Work?

This paper investigates whether official Japanese intervention in the JPY/USD exchange rate over the January 1999 to March 2004 time period is effective. By integrating the official intervention data with a comprehensive set of newswire reports capturing days on which there is a rumor or speculation of intervention, the paper also attempts to shed some light on through which of the two channels, the signaling channel in a broad sense or the portfolio balance channel, effective Japanese intervention works. The results suggest that Japanese intervention is effective during the first 5 years of the sample and ineffective during the last 3 months of the sample, thereby providing an ex-post rationale for why Japan intervened as well as for why the interventions stopped. Moreover, the results suggest that when Japanese intervention is effective, it works through a portfolio-balance channel. The results do not rule out that effective intervention also works through signaling.exchange rates; foreign exchange market intervention; channels of Transmission

Foreign Exchange Intervention When Interest Rates Are Zero: Does the Portfolio Balance Channel Matter After All?

The Japanese zero-interest rate period provides a “natural experiment” for investigating the effectiveness and transmission channels of sterilized intervention when traditional monetary policy options are constrained. This paper takes advantage of the fact that all interventions in the JPY/USD market during the zero-interest rate period are sterilized sales of JPY and, therefore, none of these interventions can signal a future interest rate decrease. In order to further assess through which transmission channel these interventions work, the analysis integrates official daily Japanese intervention data with a comprehensive set of rumors data that capture interventions of which the market is aware. Market awareness is a necessary condition for intervention to disseminate information and work through channels other than the portfolio balance channel. The results of the time series analysis show that intervention, on average, induces a statistically and economically significant same-day depreciation of the JPY. Market awareness is shown to be unimportant. Consequently, the effects of Japanese interventions during the zero-interest rate period are consistent only with the portfolio balance channel. This is a remarkable finding, demonstrating that sterilized intervention is, in principle, an independent policy instrument.exchange rates; foreign exchange market intervention; channels of transmission

Effectiveness of Official Daily Foreign Exchange Market Intervention Operations in Japan

Japanese official intervention in the foreign exchange market is of by far the largest magnitude in the world, despite little or no evidence that it is effective in moving exchange rates. This paper investigates the effectiveness of intervention using recently published Japanese official daily data and an event study methodology. Focusing on daily Japanese and US official intervention operations, we identify separate intervention episodes' and analyze the subsequent effect on the exchange rate. Using the non-parametric sign test and matched-sample test, we find strong evidence that sterilized intervention systemically affects the exchange rate in the short-run (less than one month). This result holds even when intervention is not associated with (simultaneous) interest rate changes, whether or not intervention is secret' (in the sense of no official reports or rumors of intervention reported over the newswires), and against other robustness checks. Large-scale (amounts over $1 billion) intervention, coordinated with the Bank of Japan and the Federal Reserve working in unison, give the highest success rate

Monetary Policy News and Exchange Rate Responses: Do Only Surprises Matter?

This paper shows that exchange rates respond to only the surprise component of an actual US monetary policy change and that failure to disentangle the surprise component from the actual monetary policy change can lead to an underestimation of the impact of monetary policy, or even to a false acceptance of the hypothesis that monetary policy has no impact on exchange rates. This finding implies that there is a need for reexamining the empirical analyses of asset price responses to macro news that do not isolate the unexpected component of news from the expected element. In addition, we add to the debate on how quickly exchange rates respond to news by showing that the exchange rates under study absorb monetary policy surprises within the same day as the news are announced.expectations; monetary policy; federal funds futures; exchange rates

Do Exchange Rates Respond to Day-to-Day Changes in Monetary Policy Expectations? Evidence from the Federal Funds Futures Market.

This paper is the first to utilize the informational content embodied in Federal funds futures contracts for extracting day-to-day changes in expectations of future US monetary policy, in the context of a study of day-to-day exchange rate changes. We analyze more than 12 years of daily exchange rate data and show that continuous day-to-day changes in expectations of future US monetary policy has a significant and systematic impact on day-to-day changes in exchange rates. Our results imply that monetary policy matters for daily exchange rate determination in more ways than merely through infrequent, actual policy changes. Furthermore, when focusing on the actual monetary policy changes, the paper confirms that only the unexpected element of a policy change impacts exchange rates. The presented findings are generally consistent with the notion that exchange rates are forward-looking asset prices.expectations, monetary policy; federal funds futures; exchange rates

Real-Time Effects of Central Bank Interventions in the Euro Market

This paper investigates the real-time effects of foreign exchange intervention using official intraday intervention data provided by the Danish central bank. Denmark is currently pursuing an active intervention policy under the provisions of the Exchange Rate Mechanism (ERM II) and intervenes on a discretionary basis when considered necessary. Prior participation in ERM II is a requirement for adoption of the Euro. Therefore, our study is of particular relevance for the new European Union member states that are either currently participating in ERM II or expected to do so at a later date as well as for Denmark. Our analysis employs the two-step weighted least squares estimation procedure of Andersen, Bollerslev, Diebold and Vega (2003) and an array of robustness tests. We find that intervention exerts a statistically and economically significant influence on exchange rate returns when the direction of intervention is consistent with fundamentals and intervention is carried out during a period of high exchange rate volatility. We also show that the exchange rate does not adjust instantaneously to the unannounced and discretionary interventions under study. We conclude that intervention can be an important short-term policy instrument for exchange rate management.foreign exchange intervention; intraday data; ERM II

Foreign Exchange Intervention and Monetary Policy in Japan, 2003-04

This article examines the rationale behind the massive increase in Japanese foreign exchange market intervention operations in 2003-04, and evaluates its effectiveness both in limiting yen exchange rate appreciation and influencing the direction of monetary policy. The two main questions addressed in this study are: Was the intervention effective in slowing exchange rate appreciation compared to a counterfactual case with no intervention? And, has intervention on such a large scale authorized by the Ministry of Finance been able to directly influence liquidity creation or indirectly influence the stance of Bank of Japan policy?foreign exchange intervention; Japanese monetary policy
