Yen Weakness Continues Amid Joint Intervention Fails to Yield Results

The Japanese yen has continued its downward trend despite a rare joint intervention by the United States and Japan to stabilize the currency. The won-yen exchange rate has fallen to its lowest level since July 23, 2024, at 887.8 won. This decline is attributed to Japan's weak economic fundamentals, including a potential growth rate of below 1 percent.

The joint intervention had initially lifted the yen, pushing the won-yen rate up to 910.7 won on August 3. However, its effects were short-lived, and the rate resumed its decline. Market participants see little chance of a sustained rebound, citing limited room for further intervention and structural headwinds.

Analysts point to Japan's expansionary fiscal stance as a major contributor to the yen's weakness. The Takaichi cabinet has pledged to invest over 370 trillion yen in areas including AI through 2040, which will lead to higher government bond issuance and downward pressure on the currency.

The gap between US and Japanese benchmark interest rates is also weighing on the yen. Despite the Bank of Japan raising its rate from 0.75 percent to 1 percent in June, the spread with the US rate remains significant.
