The U.S. urges Japan to continue tightening its monetary policy.

U.S. Unusually Identifies Japan's Broker Detectorry Policy

In a rare move, the U.S. Treasury's exchange rate report submitted to Congress on June 6 explicitly mentioned the Bank of Japan's monetary policy, urging Japan to continue normalizing its monetary policy. The report highlighted that the Bank of Japan should persist in raising interest rates to address domestic economic conditions and support the "normalization of the yen's weakness against the dollar," contributing to necessary structural adjustments in bilateral trade.

This report marks an increased focus from Washington on Tokyo's long-standing ultra-low interest rate policy. The U.S. Treasury believes that Japan's prolonged easy monetary policy is a key factor in the yen's ongoing weakness and also affects global trade balance.

Yen's Weakness Draws Attention

In the exchange rate report, the U.S. Treasury straightforwardly stated that Japan's monetary policy is indirectly weakening its currency, thereby affecting trade structures. The report stated: "The Bank of Japan should continue tightening monetary policy according to its domestic economic growth and inflation fundamentals to support the normalization of exchange rate mechanisms and structural trade rebalancing."

The report also mentioned that Japan's government investment tools—such as large public pension funds—should aim at "risk-adjusted returns and diversification" in overseas investments, instead of influencing exchange rate trends.

Gradual Interest Rate Hikes by the Bank of Japan

Starting from the end of 2023, the Bank of Japan has gradually withdrawn from large-scale monetary stimulus measures and in January 2024 raised short-term interest rates to 0.5% for the first time. This marks Japan's first attempt in years to restore traditional interest rate policies, reflecting its confidence in achieving the 2% inflation target.

Nonetheless, due to external pressures from the recent U.S. tariff increases, the Bank of Japan lowered its economic growth forecast in May 2025, leading the market to expect that its future interest rate hike pace will remain cautious.

Market Perspective: Delayed Rate Hikes Weaken Yen

Financial markets generally believe that the Bank of Japan's response is overly slow, causing the yen to continue weakening against the dollar and other major currencies. Currently, the exchange rate of the yen to the dollar remains near a 34-year low, raising international concerns about "competitive currency devaluation."

The U.S. hopes that by advocating for rate hikes, the yen will emerge from its weak state and alleviate the imbalances in global trade structures caused by exchange rate fluctuations. Analysts point out that although the U.S.'s stance is of a "suggestive" nature, its influence cannot be ignored in the current context of intensified global monetary policy competition.

The challenge currently facing the Bank of Japan is how to advance rate hikes amid modest inflation recovery and still fragile economic growth. If policies are tightened too quickly, it could impact domestic consumption and business investment; however, if too slow, it could lead to increased external pressure, particularly from U.S. concerns about exchange rates.

Although Bank of Japan officials express willingness to "further raise rates when conditions are right," in the broader context where global policy tightening has peaked, its path forward becomes more complicated.
