History of Japan’s intervention in currency markets

TOKYO (Reuters) – Japanese authorities held an emergency meeting this week to discuss the weak yen and suggested they were ready to intervene in the market to stop what they described as disorderly and speculative moves in the currency.

The yen rallied on the news, coming off 34-year low of 151.97 per U.S. dollar after top currency diplomat Masato Kanda said he “won’t rule out any steps to respond to disorderly FX moves”.

Japan last intervened in October 2022 as the yen plumbed lows near 152 per dollar. It was then estimated to have spent as much as 9.2 trillion yen ($60.78 billion) defending the currency.

Here is a timeline of moves in foreign exchange markets by the Bank of Japan (BOJ).

Oct. 21-24, 2022 – The dollar plunged more than 7 yen at one point on Oct. 21 in a decline sources attributed to authorities’ yen buying. Japanese Finance Minister Shunichi Suzuki declined to confirm whether the government had intervened in the currency market.
