Japan, US Stage Joint Currency Intervention Amid Weak Yen Fears

Japan and the US intervened in the foreign exchange market for the first time in 15 years, buying yen on August 3 to counter a strong dollar. The joint intervention was sparked by concerns over Prime Minister Sanae Takaichi's proactive fiscal policy, which is driving up demand for the yen.

The yen surged against the US dollar after the intervention, reaching ¥157.20 per dollar, its strongest level in about 2½ months. This move aims to stabilize the exchange rate and prevent a weak yen from becoming a major issue.

According to Japanese government officials, Tokyo had long coordinated with Washington on this joint currency intervention, which was based on a joint statement announced in September last year by Japan and US finance ministers. The statement suggested the possibility of currency intervention in response to 'excess volatility and disorderly movements in exchange rates.'

Takashi Kiuchi, an executive economist at Nomura Research Institute, stated that Friday's joint intervention reflects matching interests between the two countries, but the effect will be temporary, and the exchange rate may return to pre-intervention levels within a few weeks.
