Foreign exchange markets are bracing for potential Japanese government intervention as the yen nears its weakest point against the dollar in nearly two years. Japan has already spent approximately $72.52 billion on currency intervention between late April and mid-May, yet traders remain skeptical that such measures alone can reverse the trend.

The dollar recently traded at 161.82 yen, just shy of its June 22 peak of ¥161.92. A breach above that level would push the yen to its lowest since July 2024. Growing speculation about Federal Reserve rate hikes before year-end has accelerated the currency's decline, making intervention more likely.

Chief Cabinet Secretary Minoru Kihara reiterated Tuesday that authorities will act as needed, stating officials are ready to take appropriate action at any time. His comments followed an online meeting between Finance Minister Satsuki Katayama and U.S. Treasury Secretary Scott Bessent, which analysts at Nomura suggest may have discussed recent JPY weakness.

Despite the substantial intervention spending, market participants doubt it will significantly alter the yen's trajectory given persistent rate differential pressures and global carry trade dynamics that continue favoring dollar strength.
