US and Japan Team Up to Boost Yen in Rare Joint Intervention

The United States and Japan have intervened in the foreign exchange market to strengthen the yen, which has been weakening against the dollar due to higher interest rates in the US. The joint intervention is a rare move, with the last such action happening nearly 30 years ago during the Asian Financial Crisis.

The dollar weakened sharply against the yen after the news of the intervention, with the greenback trading at near 156 yen compared to its recent high of around 163 yen in July. The US Treasury Secretary said that Washington would 'not hesitate' to participate in further joint intervention if necessary.

Analysts warn that while the short-term outlook for the yen has improved, the long-term challenges remain. Japan's interest rates are much lower than those in the US, making the dollar more attractive and driving up the cost of imports, which fuels inflation and increases living costs for Japanese households.
