Japan and US Confirm Rare Joint Intervention to Prop Up Yen

Japan and US Confirm Rare Joint Intervention to Prop Up Yen

President Trump announced that Washington was helping to prop up the Japanese currency as a sign of friendship and to support the global economy. Responding to a reporter’s query about why the US was stepping in, Trump stated that they had a weakening yen and wanted a little bit of help, and added that they were always there for Japan. Analysts noted that the intervention highlights both nations’ resolve to prevent global spillovers resulting from a sell-off in the yen and Japanese government bonds, which has added pressure on rising US Treasury yields.

Market Impact and Currency Movements

Following President Trump’s remarks, the US dollar fell 0.2 percent to 157.07 yen, moving well off the 40-year high near 164 yen recorded late last month. However, the dollar subsequently rose back to 157.70 yen following the formal statement issued by the Japanese Finance Ministry.

Japan’s Ministry of Finance stated that Friday’s yen-buying operation conducted alongside the US Treasury Department successfully countered excessive volatility and disorderly movements in the Japanese yen in recent months. The ministry emphasized that it remains attentive and in close communication with counterparts at the US Treasury, adding that officials would not hesitate to conduct further joint intervention. Bank of Japan data indicated that Tokyo may have sold as much as $58.97 billion to buy yen during an intervention in New York markets on Thursday, prior to Friday’s confirmed joint effort with Washington.

US Treasury Secretary Scott Bessent also confirmed the joint effort, stating on Sunday that Washington would not hesitate to participate in further joint intervention. In a separate statement published on X, Bessent noted that they strongly supported Japan’s decisive market and monetary steps to correct the substantial undervaluation of the yen, while repeating his calls for further interest rate hikes by the Bank of Japan.

Broader Economic Pressures and Policy Responses

Japan has faced continuous struggles to curb a relentless drop in its currency, a trend that drives up import prices, stokes broader inflation, and impacts household wallets as well as the approval ratings of Prime Minister Sanae Takaichi. The joint currency operation marks the first such collaboration since a 2011 coordinated action to weaken the yen following the devastating earthquake in eastern Japan.

In line with Secretary Bessent’s calls for higher borrowing costs, the Bank of Japan offered its most explicit signal to date regarding an early rate hike, even while keeping monetary policy steady at its meeting. Previously, the central bank implemented a June rate hike to a 31-year high of 1 percent, though that move provided the struggling currency with little lasting boost. Prior efforts by Japan in April and May to buy the yen had similarly triggered only brief rebounds.

The wider currency actions also involved regional coordination. South Korea stepped in to buy its won currency on Thursday, with market sources describing the simultaneous currency defenses as part of a broader regional push alongside Japanese authorities.
