Previous studies have mainly used reports in the financial press to analyze the link between the interventions of the Bank of Japan (BoJ) and exchange rate volatility. We use official intervention data for the period 1993 - 2000 that were released only recently by the BoJ and find that interventions of the BoJ increased the volatility of the $/yen exchange rate.

We consider the effect of interventions by the Bank of Japan in the foreign exchange market during the period 2000-2004. During this period the interventions are of substantial magnitude, relatively frequent, not co-ordinated and take place within the 'zero interest rate' monetary policy regime. Only scant evidence exists in the literature on the spillover effect and the impact on covariance in both daily and intraday frameworks, as well as on analyzing the characteristics of intraday volatility dynamics on both intervention days and non-intervention days. In contrast to earlier studies, our analysis does not hinge on the assumption that intervention always increases the volatility of the exchange rate. We perform rolling estimations of a Multivariate GARCH model, use the quartile plots of intraday volatility, and perform equal variance tests to investigate intraday volatility characteristics on intervention and non-intervention days using both daily and 15-minute data. Our findings suggest that Band of Japan interventions decrease the volatility of the yen/USD exchange rate. This result contrasts with the findings of earlier studies which typically find that interventions result in higher volatility. The effect of interventions on the yen/USD volatility depends on the different states that the market experiences and its impact is different under high and low levels of exchange rate volatility. We also find the intraday volatility is less heteroskedastic within the intervention day and this has implications for volatility forecasting. We find strong evidence that intervention in the USD/YEN increases the volatility of the Euro/Yen.

In this paper we test for the short-term impact of foreign exchange intervention on both the level of the yen/dollar exchange rate and the volatility in the yen/dollar markets. Using newly released data on Japanese foreign exchange intervention, our global GARCH estimation suggests that Japanese foreign exchange interventions between 1991 and 2002 had the intended effect on the same day, but at the cost of higher exchange rate volatility. Testing for the robustness of this finding we show that the results are highly dependent on the time period. From 1991 to 1998 Japan's official currency purchases were unsuccessful and coincided with increased exchange rate volatility. Since 1999 official Japanese currency purchases seem to have had the intended short-term effect while exchange rate volatility is lower. To this end, the paper provides evidence for successful foreign exchange intervention on the same day in Japan's liquidity trap where the borderline between sterilized and unsterilized foreign exchange intervention became blurred.

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.

Dollar and Yen analyzes the friction between the United States and Japan from the viewpoint of exchange rate economics. From the mid-1950s to the early 1990s, Japan grew faster than any other major industrial economy, displacing the United States in dominance of worldwide manufacturing markets. In the 1970s and 1980s, many books appeared linking the apparent decline of the United States in the world economy to unfair Japanese practices that closed the Japanese market to a wide range of foreign goods. Dollar and Yen analyzes the friction between the United States and Japan from the viewpoint of exchange rate economics. The authors argue against the prevailing view that the trade imbalance should be corrected by dollar depreciation, saying that adjustment through the exchange rate is both ineffective and costly. Stepping outside the traditional dichotomy between international trade and international finance, they link the yen's tremendous appreciation from 1971 to mid-1995 to mercantile pressure from the United States arising from trade tensions between the two countries. Although sometimes resisted by the Bank of Japan, this yen appreciation nevertheless forced unwanted deflation on the Japanese economy after 1985--resulting in two major recessions (endaka fukyos). The authors argue for relaxing commercial tensions between the two countries, and for limiting future economic downturns, by combining a commercial compact for mutual trade liberalization with a monetary accord for stabilizing the yen-dollar exchange rate.

This paper uses recently released official data on the foreign exchange market interventions of the Bank of Japan (BoJ) in the yen/U.S. dollar market during the period 1991-2001 in order to examine the motivation for the intervention policy of the BoJ. We also compare the intervention policy of the BoJ and the Federal Reserve. Our results suggest that the BoJ regularly responded to deviations of the yen/U.S. dollar exchange rate from a short-term and a long-term exchange rate target. By contrast, the Fed intervened only occasionally and seemed to have merely reinforced BoJ interventions.
