The Japanese yen weakened to a fresh low against the US dollar on Monday, reaching levels not seen since late July, with USD/JPY trading around 149.50, up from the previous close. The decline reflects persistent concerns over Japan’s fiscal position and the interest rate gap between the United States and Japan. The Bank of Japan has maintained an ultra-loose monetary policy, while the Federal Reserve has signaled a slower pace of rate cuts, keeping US yields relatively high and reducing the yen’s appeal in carry trades (borrowing cheaply to invest in higher-yielding assets). Japan’s public debt exceeds 200% of GDP, and recent stimulus packages and higher defense spending have added to investor concerns, although officials have reiterated their commitment to fiscal discipline. Traders are watching for possible Japanese intervention as the yen approaches levels that previously prompted verbal warnings from the Ministry of Finance. A break above 150.00 could open a test of 152.00, the high from last October, though the pace of the move and intervention risk remain uncertain. A weaker yen supports exporters and raises the value of overseas earnings but increases import costs, particularly for energy and raw materials, potentially adding to inflation and pressure on household budgets. Investors will focus on upcoming US inflation and employment data, Japan’s fiscal policy announcements, and Bank of Japan comments on exchange rates ahead of its policy meeting scheduled for late October.
