Japan Signals Readiness to Intervene as USD/JPY Nears 161 Amid Yen Weakness

Japan has reaffirmed its readiness to act against excessive currency volatility as the Japanese yen continues to weaken against the U.S. dollar. Chief Cabinet Secretary Minoru Kihara stated on Thursday that the government is prepared to respond to foreign exchange market movements at any time if necessary, highlighting growing concerns over the yen’s sharp decline.

The USD/JPY exchange rate briefly climbed to 160.795 on Wednesday, its highest level in nearly two years, before settling around 160.76 on Thursday. The move erased gains achieved after Japan’s currency intervention in late April, underscoring the ongoing pressure on the yen despite official efforts to support it.

Kihara noted that while a weaker yen can benefit exporters by making Japanese goods more competitive overseas, it also raises import costs, increasing financial pressure on businesses and households. He emphasized that the government would continue monitoring currency market developments closely and assess the broader economic impact.

The yen’s latest decline follows a strong rally in the U.S. dollar after the Federal Reserve maintained interest rates but signaled the possibility of another rate hike later this year. In contrast, the Bank of Japan recently raised interest rates to 1%, the highest level in 31 years, but the move has done little to strengthen the currency. The gap between Japanese and U.S. interest rates remains substantial, with the Fed’s benchmark rate standing at 3.50%–3.75%.

Japanese authorities have already spent a record 11.7 trillion yen (approximately $72.9 billion) on foreign exchange interventions between late April and early May. However, the impact proved temporary as the yen has since surrendered all post-intervention gains.

Market analysts believe the widening monetary policy gap between Japan and other major economies remains the primary driver behind yen weakness. Some economists expect the Bank of Japan to implement another interest rate hike later this year, potentially in October or December, to address inflation risks and stabilize the currency. Nevertheless, investors remain bearish on the yen, with speculative short positions reaching their highest levels since mid-2024.

Despite continued intervention risks, analysts suggest the USD/JPY pair is unlikely to rise significantly above the 160 level without prompting stronger action from Japanese authorities. As inflation concerns persist and global interest rate expectations evolve, the direction of the yen and future Bank of Japan policy decisions will remain key factors for currency markets.
