Japan FX Intervention Surges 290% With Record $34B Single-Day Injection

Japan deployed an estimated $34 billion to buy yen last Friday, setting a new single-month intervention record. Cumulative actions may exceed prior highs as USD/JPY volatility persists.

Woofun AI reports that Japan's Finance Minister Okatsuka confirmed foreign exchange market intervention occurred last Friday, with authorities deploying approximately ¥5.33 trillion ($34 billion) to purchase yen. This figure represents the largest single-month intervention scale in history. Bloomberg estimates align with this amount, suggesting that combined with previous actions, total recent interventions could surpass the prior record of ¥11.73 trillion.

The intervention follows the USD/JPY rate reaching 164, a high not seen since 1986, prompting efforts to counter speculative short positions. Prior to this, an estimated ¥8.45 trillion was injected last Thursday, potentially marking the largest single-day intervention ever. U.S. Treasury Secretary Benson indicated potential for further cooperation, while markets await the Ministry of Finance’s quarterly report this Friday and monitor Bank of Japan rate hike expectations for September.
