US Buys Yen for First Time in a Decade

The Cliff News | 3 August 2026

In a significant move underscoring international economic cooperation, the United States has purchased Japanese yen, marking the first such bilateral intervention in the currency market in over a decade. President Donald Trump announced the action on Sunday, characterizing it as a "signal of friendship" aimed at bolstering the yen, which had fallen to a 40-year low against the dollar.

Speaking to reporters, President Trump stated that Japan "wanted a little bit of help" with its weakening currency. This joint action with Japan, confirmed on Friday, seeks to reverse the yen’s depreciation. The weakening trend has reportedly been exacerbated by rising energy costs, influenced by the ongoing Iran war.

Economic Rationale for Intervention

The U.S. has a vested interest in a stronger yen. A stronger dollar makes American exports more expensive for international buyers, potentially hindering U.S. trade. Conversely, while a weaker yen benefits Japanese exporters and boosts tourism to Japan, it also increases the import costs for Japan, particularly for essential commodities like oil and gas, thereby fueling domestic inflation.

Japan’s Finance Minister, Satsuki Katayama, issued a statement on Monday confirming the action. She described the intervention as a measure to "counter excessive volatility and disorderly movements in the Japanese yen in recent months," highlighting concerns over the currency's recent erratic fluctuations.

Official Confirmations and Statements

The Federal Reserve Bank of New York was reportedly involved in selling euros for yen on behalf of the U.S. Treasury Department, according to initial reports by the Financial Times. Treasury Secretary Scott Bessent also acknowledged the intervention on X (formerly Twitter) on Sunday, emphasizing the Treasury Department's readiness to "participate in further joint intervention."

Secretary Bessent further stated, "We strongly support Japan’s decisive market and monetary steps to correct the substantial undervaluation of the yen." This indicates a unified front between the two nations to stabilize the yen's value and address what is perceived as a significant under-valuation.

Global Economic Implications

President Trump expressed optimism that supporting the yen would be "good for the world economy," suggesting that the United States would also see financial benefits from the move, though specific details were not elaborated upon. Such currency interventions can have ripple effects across global markets, influencing trade balances, investment flows, and inflation rates worldwide.

This collaborative effort highlights the complex interplay of international finance and national economic interests. The U.S. intervention signals a commitment to global economic stability and a willingness to engage in direct market actions to achieve shared objectives with key allies like Japan.
