Experts agree: Sustained Japanese Yen weakness is likely to trigger another intervention

The Japanese Yen is experiencing a decline as worries about the Federal Reserve's hawkish stance and the possibility of Japanese intervention in the forex market grow. Despite the Bank of Japan's recent rate hike, the Yen remains under pressure following a strong US Dollar rebound. The Federal Reserve increased its benchmark interest rate for the first time in three years, with Fed Chair Kevin Warsh delivering a more aggressive message than anticipated.

This has led investors to anticipate further rate hikes, pushing US Treasury yields higher and supporting the US Dollar. The Bank of Japan's decision to raise its policy rate by 25 basis points to 1.25% was met with mixed responses, with two members of the policy board advocating for more patience before proceeding with additional tightening.

This uncertainty is weighing on the Yen. The US Dollar Index, which tracks the Dollar's performance against a basket of six major currencies, is near a seven-week high. Market participants are closely monitoring the Federal Reserve's upcoming meeting and the US-China summit for further clues about potential interventions from Japanese authorities.
