FX Intervention

Ministry of Finance publishes statistics on FX Intervention under the title of "Foreign Exchange Intervention Operations". The Japanese government has in the past intervened extensively to counter currency movements it deemed undesirable. The most significant of Japan's interventions took place over four periods to restrain appreciations of yen; 1993-1996, 1999-2000, 2001-2004 and 2010-2011. Heavy buying of US dollars has resulted in an accumulation of foreign exchange reserves to the tune of 1.26 trillion dollars as of September 2016. On rare occasions, in December 1997 and April 1998, Japan intervened to purchase yen.

The FX Intervention statistics are officially published with Yen denomination. The amount of FX intervention expressed in US dollar in our (JMA) page is our conversion. To convert the amount into US Dollar, we use exchange rates published by the Bank of Japan, "US Dollar/Yen, Average in the month" for monthly figures and “US Dollar/Yen Spot Rate at 17:00 in JST" for daily figures.
