Bank of Japan Deputy Governor Signals Timely Rate Hikes

The Japanese yen strengthened against most G-10 and Asian currencies on August 27, 2026, as markets anticipated a speech by Ryozo Himino, Deputy Governor of the Bank of Japan. The U.S. dollar declined 0.1% to 159.15 yen and the euro fell 0.1% to 185.49 yen while traders sought signals regarding a potential 25 basis point interest rate hike in September.

Speaking to business leaders in Saitama, Himino stated that the central bank may need to raise interest rates in a timely manner to prevent inflation from accelerating beyond the 2% price stability target. He warned that underlying inflation deviating upward would adversely impact the economy and noted that the bank must pay greater attention to upside price risks than in the past, specifically highlighting the role of a weak yen in driving inflation.

Himino argued that timely adjustments would avoid the need for abrupt rate hikes in the future and help distribute assets more efficiently toward growth-potential investments. These remarks align with market expectations, as overnight index swaps imply an 85% probability of a rate move in September.
