Reserve Bank’s blunt warning just days before next interest rates decision

The Bank of Japan hiked its interest rates to a 31-year high on Friday, indicating its intention to further increase borrowing costs and join other major central banks in the battle against persistent inflation. This was the first rate hike in three months and brought the rates closer to the levels deemed neutral by the central bank to the economy, moving away from decades of low rates that made the yen a cheap global funding currency.

The move was in response to soaring oil costs, expansionary fiscal policies, and surging demand for AI investment, all of which have contributed to global inflation risks. The bank raised its policy rate to 1.25 percent from one percent by a 7-2 vote during a two-day meeting. However, some board members, Toichiro Asada and Ayano Sato, dissented.

Wholesale inflation remains elevated, and price pressures from business-to-business trading have started to affect consumer prices. Underlying inflation has approached two percent as companies continue to pass on higher wages and inflation expectations keep rising. While developments are aligning with the bank's forecast, there is a risk that underlying inflation could stray from the central bank's two percent target.

Markets are watching governor Kazuo Ueda's conference for insights on the pace and timing of future rate hikes. The bank's rate remains lower than those of the European Central Bank and the Federal Reserve, which may keep the yen weak against other currencies, raising import costs and inflation.
