BOJ lifts rates to 31-year high, pivots towards preemptive inflation fight - Reuters

The Bank of Japan raised its policy rate to a 31-year high, according to Reuters, marking a further step away from the ultra-loose monetary stance that defined the past decade. The move signals a subtle but important shift in the central bank's reaction function: rather than waiting for sustained inflation to take hold, policymakers appear increasingly willing to act preemptively against price pressures.

For markets, the significance lies less in the headline level than in the direction of travel. A BOJ willing to tighten ahead of clear inflation evidence can influence global bond yields, since Japanese investors are major holders of overseas debt. It also affects the yen, whose strength or weakness feeds back into Japanese import costs and, in turn, inflation itself.

What to watch: the BOJ's communication on future moves, wage growth data, and whether inflation proves durable enough to justify further tightening. For now, the shift reinforces that Japan is no longer an outlier in the global rate cycle.
