Japanese yen weakens to session low of 159.72 per dollar

The Japanese yen (JPY) weakened to a session low of 159.72 per U.S. dollar (USD) on March 13, 2026, extending its decline amid heightened political uncertainty and divergent monetary policy trajectories between Japan and the United States. Prime Minister Sanae Takaichi’s potential call for a snap election in early February has fueled speculation about expansionary fiscal measures, adding pressure on the yen as investors anticipate policy-driven stimulus according to market analysis. Meanwhile, the Bank of Japan (BoJ) remains cautious about the timing of its next rate hike, despite Governor Kazuo Ueda’s recent reaffirmation of a policy normalization path as reported. This uncertainty contrasts with the U.S. Federal Reserve’s (Fed) expected rate-cut trajectory, with markets pricing in two additional cuts in 2026, deepening the yield differential favoring the dollar according to traders.

Geopolitical tensions further weigh on the yen. China’s recent ban on rare earth exports to Japan has heightened supply-chain risks for Japanese manufacturers, while broader East Asian diplomatic strains dampen risk appetite for the safe-haven currency as data shows. Japanese Finance Minister Satsuki Katayama has expressed concerns over the yen’s “one-sided” decline, signaling limited tolerance for further weakness according to financial reports. However, intervention risks remain contingent on the USD/JPY pair approaching the psychologically significant 160.00 level, where past central bank actions have historically occurred as market analysis indicates.

Technically, the USD/JPY pair holds above its rising 50-day simple moving average (SMA) and a relative strength index (RSI) of 67.47, suggesting sustained bullish momentum according to technical indicators. Traders will closely watch upcoming U.S. consumer inflation data for clues about the Fed’s policy path, which could influence near-term USD strength. For now, the yen’s vulnerability reflects a complex interplay of domestic political risks, BoJ hesitancy, and global dollar demand amid geopolitical volatility.
