Trump's Yen Concerns Fuel BOJ Rate Hike Speculation

US President Donald Trump's comments on the weak yen have sparked concerns that Tokyo will be pressured to stabilize the currency, potentially leading to another interest rate hike by the Bank of Japan (BOJ) in October. The BOJ raised its policy rate by 0.25 percentage point to 1.25% from 1.0% just last month.

The yen's weakness could have significant implications for the US trade balance and long-term interest rates, according to analysts. A weak yen can strengthen the price competitiveness of Japanese goods, widening the US trade deficit with Japan, while also potentially leading to a selling spree of yen and Japanese government bonds that could spill over into selling of US Treasurys.

The market has begun pricing in the chance of an October hike, with expectations for rate increases through October standing at 0.31 times, meaning there's more than a 30% chance of another 0.25 percentage point increase next month, according to Totan Research based on the interest-rate swap market.
