Japanese authorities conducted a record single-day yen-buying intervention in April, selling approximately $40 billion to stem the yen's slide. The largest operation on April 30 involved 6.28 trillion yen, temporarily strengthening the currency before it resumed its decline.

The intervention highlights the significant pressure on the yen and the lengths to which Japanese authorities are willing to go to support the currency, potentially impacting global currency markets and carry trades.
Japanese authorities conducted a record single-day intervention in foreign exchange markets in April, selling approximately $40 billion worth of dollars to stem the yen's slide. Quarterly data from the Ministry of Finance revealed that the largest operation on April 30 involved 6.28 trillion yen, surpassing the previous single-day record set on April 29, 2024. The intervention, part of three days of operations between April 30 and May 6, helped lift the yen from a near two-year low of 160.725 per dollar to around 155 by May 6. However, the currency's broader downtrend was not reversed, and the yen resumed its slide, reaching 40-year lows below 163 per dollar in July. This prompted further intervention last week, this time in coordination with Washington.
