U.S. Signals Possible Support for Yen as Markets Watch for Further Currency Intervention

BY COMFORT OGBONNA

The United States has alerted several major banks that it may take action in the Japanese yen market, a move that has intensified speculation of further efforts to stabilize the Japanese currency following Japan’s recent intervention to halt its sharp decline against the U.S. dollar.

According to a person familiar with the matter, the U.S. Treasury informed financial institutions through the Federal Reserve Bank of New York that they should remain prepared for potential future market operations. The communication came just one day after Japanese authorities intervened in the foreign exchange market, helping the yen record its strongest weekly performance since February.

The possibility of additional intervention immediately influenced currency trading. The yen strengthened against the dollar on Friday, recovering significantly after falling to levels not seen in nearly four decades earlier in the week. The currency traded around 159 yen per dollar after previously weakening to more than 163 yen per dollar during Thursday’s session.

Officials have not disclosed how any potential U.S. involvement would be carried out, and there has been no formal confirmation that intervention is imminent. Market participants noted, however, that the Federal Reserve has maintained long-standing dollar liquidity swap arrangements with the Bank of Japan and several other major central banks, providing an established framework for financial cooperation during periods of market stress.

Japan’s top currency official declined to comment directly on market intervention but suggested that coordination with U.S. authorities has extended beyond verbal support. He pointed to recent market activities, including so-called “rate checks,” in which government officials request exchange-rate quotations from financial institutions. Such inquiries are often viewed by traders as an early signal that official intervention may be under consideration.

Currency analysts said reports of U.S. preparations have increased expectations that authorities remain willing to act if excessive volatility continues.

The possibility of coordinated action has heightened caution among investors, who are closely monitoring movements in the foreign exchange market after the yen’s prolonged period of weakness.

The U.S. Treasury emphasized that it continues to maintain close coordination with Japanese financial authorities but stopped short of confirming any plans for direct market intervention. Treasury officials also highlighted ongoing cooperation between the two countries and expressed confidence in Japan’s economic leadership and monetary policies.

The Treasury Secretary said he expects to meet with Bank of Japan Governor Kazuo Ueda during the upcoming meeting of finance ministers and central bank governors later this summer, where global economic conditions and financial stability are expected to be key topics of discussion.

Earlier this week, U.S. officials publicly stated that the yen appears significantly undervalued and argued that excessive currency volatility is harmful to both financial markets and economic stability. They also expressed confidence that Japan’s current economic policies would strengthen the country’s long-term fundamentals.

The remarks marked one of the strongest public acknowledgments by U.S. officials that the yen’s recent depreciation may have moved beyond levels justified by economic conditions.

The Japanese currency has remained under pressure for much of the past year as interest rate differences between the United States and Japan encouraged investors to favor higher-yielding dollar-denominated assets. Although the Bank of Japan has begun moving away from years of ultra-loose monetary policy, borrowing costs in Japan remain well below those in the United States, continuing to weigh on the yen.

Currency intervention is generally considered an extraordinary measure used only when exchange-rate movements become excessively volatile or threaten broader financial stability. Coordinated intervention by multiple governments is relatively uncommon and is typically reserved for periods of severe market disruption.

The last coordinated effort by the United States and other major economies to support the yen occurred in 2011 following the devastating earthquake and tsunami that struck Japan. That intervention was carried out by the Group of Seven nations to stabilize financial markets during a period of exceptional uncertainty.

More recently, the U.S. Treasury has also provided financial support to other countries facing currency pressures. Last year, it assisted Argentina’s efforts to stabilize its financial markets by supporting the country’s currency through existing financial mechanisms and extending a substantial currency swap arrangement designed to strengthen investor confidence.

Market participants will continue watching closely for any signs of additional intervention as policymakers seek to prevent disorderly currency movements. While officials have not confirmed that direct action is imminent, the latest communications have reinforced expectations that both the United States and Japan remain prepared to respond if volatility in the foreign exchange market intensifies further.

Investors are also expected to focus on upcoming central bank meetings, economic data releases, and policy statements that could influence interest rate expectations, as these remain the primary drivers of the dollar-yen exchange rate. The prospect of continued cooperation between U.S. and Japanese authorities has provided additional reassurance to financial markets, even as uncertainty surrounding global monetary policy and currency movements persists.
