Bank of Japan Faces Harder Policy Test After Rates Reach a 31-Year High

Tokyo, 21 September 2026 – The Bank of Japan is entering a more difficult phase of monetary normalisation after lifting its policy rate to 1.25%, the highest level in 31 years. Governor Kazuo Ueda must now balance persistent domestic price pressures, Prime Minister Sanae Takaichi’s preference for growth-supportive policy and calls from the United States for Japan to move more decisively away from the ultra-loose framework associated with Abenomics.

The latest increase extends a tightening sequence that has taken Japanese rates out of the near-zero environment that shaped global markets for years. Yet the policy rate now sits within estimates of Japan’s neutral range rather than clearly below it. That changes the character of future decisions: additional increases would be more likely to restrain demand, affect corporate financing and lift household borrowing costs instead of merely removing emergency accommodation.
