Yen's Rebound Hinges on More Than Intervention

The Japanese yen's recent decline to multi-decade lows has raised concerns among analysts that direct currency intervention may not be enough to trigger a sustained recovery.

Market participants and economists point out that while Tokyo's sporadic yen-buying operations can provide temporary relief, they do not address the root causes of the currency's weakness. The wide interest rate differential between Japan and the United States remains a dominant driver, with the Federal Reserve's policy stance and the Bank of Japan's ultra-loose monetary policy creating persistent selling pressure on the yen.

'Intervention is not a silver bullet,' said one strategist. 'It's a signal, but without policy follow-through, the effect fades quickly.'
