US and Japan Unite for Rare Yen Intervention

The US and Japan have joined forces for an unprecedented coordinated intervention to halt the yen's sharp slide. The rare effort, confirmed by Tokyo's finance ministry on July 31, involved both countries buying Japanese yen to counter excessive volatility in the currency.

The yen had been plummeting since the start of the year, squeezed between low interest rates and external shocks such as rising energy prices following a conflict in Iran. This combination pushed up Japan's trade gap and raised concerns about the country's ability to fund its record ¥122.3 trillion budget.

Treasury Secretary Scott Bessent confirmed the US participation in the intervention, stating that it was aimed at preventing excessive volatility in the yen. The operation is seen as a departure from Japan's recent pattern of intervening alone in currency markets, with some analysts noting that it marks the first time the US and Japan have jointly intervened since 2011.

The yen initially rallied after the intervention, climbing around 5% off its late-July low before drifting back somewhat. However, traders remain skeptical about the currency's underlying direction, citing the Bank of Japan's decision to hold interest rates steady at 1% despite warning that inflation could exceed its target.
