Japan Unleashes Record $40 Billion Intervention in Yen Support

Japan's Ministry of Finance revealed that it conducted its largest-ever single-day currency intervention on April 30, deploying nearly $40 billion to support the yen. The move was part of a broader record monthly intervention totalling 11.7 trillion yen conducted between April 28 and May 27.

The largest single-day operation amounted to 6.28 trillion yen (approximately $39.64 billion), surpassing the previous record of 5.92 trillion yen set in April 2024, according to the data from Japan's Ministry of Finance.

The intervention temporarily helped lift the yen from a near two-year low of 160.725 per dollar to around 155 by May 6, but the relief proved short-lived as the yen resumed weakening in the following months, slipping to fresh multi-decade lows below 163 per dollar in July.
