Japan's Inflation Update: Core CPI Slows, BOJ Policy Implications (2026)

Japan's inflation journey: A tale of moderation and persistence.

Japan's core inflation has taken a slight breather, but it's still well above the BOJ's target, keeping the heat on for further policy tightening.

Here's the breakdown:

Core Consumer Price Index (CPI) eased to 2.4% year-on-year in December, as predicted.
The slowdown was primarily due to base effects from energy prices, with a high comparison point from the previous year's fuel subsidy expiration.
The 'core-core' inflation, excluding fresh food and fuel, remained strong at 2.9% year-on-year, indicating sustained price momentum in services and labor-intensive sectors.
The BOJ is expected to maintain its policy rate at 0.75% for now, but it's ready to hike again if inflation and wages keep up their pace.

But here's where it gets controversial: While the headline inflation has cooled, the underlying inflation pressures are still intact. The 'core-core' measure's persistence above target suggests that the BOJ's gradual normalization of monetary policy is on the right track.

And this is the part most people miss: Japan's economy is showing signs of recovery, with improved wage growth and cost pass-throughs. However, policymakers are cautious due to global growth uncertainties and market volatility.

So, the BOJ's approach is clear: Pause and assess, but keep an eye on the underlying inflation. If it remains above target, expect more rate hikes later this year.

Remember, the BOJ's decision day is today, and it could have a significant impact on the yen and Japan's economic trajectory. Stay tuned!
