BOJ Lifts Rates to 31-Year High, But Dovish Sentiment Persists

The Bank of Japan (BOJ) raised its interest rates to a 31-year high on September 18, joining other major central banks in fighting inflation pressures driven by soaring oil costs. The BOJ increased its policy rate to 1.25% from 1% by a 7-2 vote, with dovish board members Toichiro Asada and Ayano Sato dissenting to the decision.

Despite the widely expected move, investors focused on a lack of explicitly hawkish guidance and the two dissenting votes, which tempered expectations for further rate hikes. The yen sank to 156.91 per dollar after the announcement, as the usual 25-basis-point hike and dovish dissenters contributed to lingering doubts about the BOJ's willingness to tighten monetary policy.

The BOJ stated that while economic and price developments are moving in line with its baseline forecast, there is a risk of underlying inflation deviating from its 2% target. Wholesale inflation remains elevated, and price pressures from business-to-business trading have started to spill over into consumer prices.
