Yen Under Pressure as Japan's Central Bank Struggles to Keep Pace with Hawkish Peers

The Japanese yen came under pressure on Tuesday as investors anticipated that Japan's central bank would struggle to keep pace with other major economies' hawkish monetary policies. The Bank of Japan's (BOJ) interest rate hike last Friday was met with two dovish dissents, which contrasted with the more aggressive stance taken by the Federal Reserve and other global central banks.

As a result, the yen slipped to 157.47 against the US dollar in Asia trading, while the euro and sterling edged up slightly. However, markets are pricing around a 30% chance that the BOJ will hike its benchmark rate to 1.5% in October, and a roughly 55% chance that the Fed will lift its funds rate window by 25 basis points to 4-4.25%.

Carlos Casanova, senior Asia economist at Union Bancaire Privée, noted that unless the BOJ tightens policy more rapidly than the Federal Reserve, the approximately 275-basis-point US-Japan rate differential will continue to support yen-funded carry trades. Markets are predicting a rise in dollar/yen rates to 160 by year-end and then moderate appreciation to 156 by mid-2027.

Elsewhere, the Reserve Bank of Australia Governor Michele Bullock warned that upside risks to inflation may be materializing, given energy prices have remained high. This led to expectations of a rate hike as soon as next week, which boosted the Aussie dollar to $0.7120.
