Japanese Foreign Exchange Interventions, 1971-2018


Book Description

We analyze the history of Japanese foreign exchange interventions from 1971 to 2018. First, we provide the best proxy for monthly interventions for the period from 1971 to 1990, when the intervention timings and amounts were not officially disclosed. The accuracy of the proxy is tested for the period when the statistics were disclosed after 1991. The proxy explains 99.8% of actual settlement-based interventions. Second, we examine conditions under which the Japanese monetary authorities are likely to intervene by estimating a policy reaction function, using the long-term data, spanning the period when intervention data have been officially disclosed and the period where our proxy is available. Third, we analyze intervention timings and amounts for Japan, the US, and Germany. Fourth, we present the episode of international coordination represented by the Plaza and Louvre agreements as a case study of notable interventions during the period.

Is Foreign Exchange Intervention Effective?


Book Description

This paper examines Japanese foreign exchanges interventions from April 1991 to March 2001 based on newly disclosed official data. All the yen-selling (dollar-purchasing) interventions were carried out when the yen/dollar rate was below 125, while all the yen-purchasing (dollar-selling) interventions were carried out when the yen/dollar was above 125. The Japanese monetary authorities, by buying the dollar low and selling it high, have produced large profits, in terms of realized capital gains, unrealized capital gains, and carrying (interest rate differential) profits, from interventions during the ten years. Profits amounted to 9 trillion yen (2% of GDP) in 10 years. Interventions are found to be effective in the second half of the 1990s, when daily yen/dollar exchange rate changes were regressed on various factors including interventions. The US interventions in the 1990s were always accompanied by the Japanese interventions. The joint interventions were found to be 20-50 times more effective than the Japanese unilateral interventions. Japanese interventions were found to be prompted by rapid changes in the yen/dollar rate and the deviation from the long-run mean (say, 125 yen). The interventions in the second half were less predictable than the first half.




Effectiveness of Official Daily Foreign Exchange Market Intervention Operations in Japan


Book Description

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.




Conquering the Fear of Freedom


Book Description

Conquering the Fear of Freedom presents an analytical review of Japanese exchange rate policy from the end of World War II to the present. It examines how authorities, starting with the imposition of draconian controls over all international financial flows, moved toward eliminating virtually all state interference regulating foreign exchange transactions, including official intervention in the foreign exchange market. It describes how policy and institutional frameworks evolved, explains their domestic and international contexts, and assesses the impacts and consequences of policy actions. Following successful exchange rate-based stabilization in the early 1950s, Japan entered the world trading system with an overvalued currency, which helped perpetuate exchange and capital controls. As the culture of administrative control became ingrained, Japan took a decidedly gradualist approach to establishing current and capital account convertibility. The protracted capital account liberalization, coupled with slow domestic financial liberalization, created large swings in the yen's exchange rate when it was floated in the 1970s. Politicization by major trading partners of Japan's large bilateral trade surplus pressured authorities to subordinate domestic stability to external objectives. The ultimate outcome was costly: from the late 1980s, Japan successively experienced asset price inflation, a banking crisis, and economic stagnation. The book concludes by arguing that the shrinking trade surplus against the background of profound structural changes, the rise of China that has diminished the political intensity of any remaining bilateral economic issues, and the world's sympathy over two decades of deflation have given Japan, at least for now, the freedom to use macroeconomic policies for domestic purposes.
