Japan CPI cools to 1.3% as BOJ faces rate dilemma

Japan’s inflation story just flipped from “sticky” to “slipping,” and it puts the Bank of Japan (BOJ) in a tighter box: cut too soon and the next energy shock could reignite prices; stay tight and a barely-growing economy risks stalling. February’s headline consumer price index (CPI) eased to 1.3 percent, the fourth straight month of cooling, while core inflation also slowed more than expected.

The key gauge for policy, CPI excluding fresh food, rose 1.6 percent in February, down from 2 percent in January and under economist forecasts. The more “under-the-hood” measure that excludes both fresh food and energy stayed hotter, with “core-core” inflation at 2.5 percent, a sign that domestic price pressure has not vanished even as the headline number drops below the BOJ’s 2 percent target.

Mechanically, this is disinflation helped by policy and base effects, not a clean victory lap. CNBC notes the cooling came with stabilizing food prices and the BOJ itself expects inflation may run below 2 percent in the first half of the year due to government measures. Yet the same reports flag the boomerang risk: energy prices are rising again, and the BOJ last week held rates at 0.75 percent while warning that the Middle East conflict could push up inflation.

That leaves officials trying to thread a needle as growth wobbles. Japan’s economy expanded just 0.1 percent year-on-year in the fourth quarter, narrowly avoiding a technical recession, so sustained sub-2 percent inflation can quickly start looking less like “normalization” and more like demand running out of steam. For households, cheaper food and subsidized utilities buy temporary relief; for policymakers, the next data prints will hinge on whether core-core inflation keeps drifting down or whether a renewed energy pass-through forces the BOJ to keep policy tighter than the growth picture would prefer.
