The Japanese yen breached the 161 level against the U.S. dollar late Thursday, marking its lowest point since July 2024 and nearing a four-decade low. The currency extended its decline to as low as 161.80 per dollar, and if it falls beyond 161.96, it would reach its weakest level since 1986 [1]. This sharp depreciation has reignited speculation that Japanese authorities may intervene in the foreign exchange market to defend the yen.
Japanese finance officials have issued fresh warnings in response to the yen's slide. Finance minister Satsuki Katayama stated at a recent G7 meeting that Japan was "prepared to take decisive action on speculative moves" in the FX markets [1]. Despite more than $70 billion in interventions by the finance ministry in May and a recent Bank of Japan rate hike—raising borrowing costs to their highest since 1995—the yen has remained under pressure [1].
Bank of Japan Deputy Governor Ryozo Himino told parliament that the central bank was closely monitoring currency movements due to their impact on the economy and inflation [1]. Experts interviewed by CNBC noted that intervention efforts have been largely ineffective, attributing the yen's weakness to structural factors such as elevated U.S. Treasury yields and the growth-focused, accommodative monetary policies of Prime Minister Sanae Takaichi's administration [1].
While the weaker yen has supported Japan's exports and economic growth, it has also raised concerns about imported inflation and the erosion of domestic household purchasing power [1].
CONCLUSION
The yen's sharp decline past 161 against the dollar has heightened intervention speculation and prompted warnings from Japanese officials. Despite previous interventions and rate hikes, structural factors continue to weigh on the currency, raising both export benefits and inflation risks. The market remains alert to potential decisive actions from Tokyo as the yen approaches historic lows.
