Tokyo Inflation Slows, But BOJ Tightening Expected to Continue

the TL;DR summary:

• Tokyo core CPI slowed to 2.3% y/y in Dec (vs. prev 2.8%,exp 2.5%), driven by lower energy and utility costs.
• Core-core CPI eased to 2.6% y/y (prev 2.8%), but remains above the BOJ’s 2% target, signalling persistent demand-side pressure.
• Headline CPI cooled to 2.0% y/y (prev 2.7%), marking the first clear deceleration since August.
• Data softens urgency, not direction, of BOJ policy; inflation remains consistent with gradual further tightening after last week’s hike to 0.75%.
• Market read-through: modest yen softness near term, JGB front-end consolidation, Nikkei supported by reduced immediate tightening risk.

Tokyo inflation cooled more than expected in December,but remained comfortably above the Bank of Japan’s 2% target,keeping the policy normalization story intact even as near-term urgency eased.

Core consumer prices in the capital, excluding fresh food, rose 2.3% y/y, slowing from 2.8% in November and undershooting market expectations of 2.5%. This marks the slowest pace as September 2023.

The core-core CPI, which excludes both fresh food and energy costs, also eased to 2.6% y/y from 2.8% previously. While this is a welcome sign, it’s still above the BOJ’s 2% target, suggesting underlying demand-side pressures remain.

Headline CPI cooled to 2.0% y/y, down from 2.7% in November. This is the first clear deceleration since August, largely due to falling energy and utility prices.

Despite the slowdown, economists don’t believe this data considerably alters the BOJ’s overall trajectory. Inflation remains consistent with a gradual further tightening of monetary policy following last week’s increase in the short-term policy rate to 0.75%. The BOJ is likely to proceed cautiously, monitoring wage growth and economic conditions before making further moves.

Market Impact: Expect modest yen softness in the near term. Japanese government bond (JGB) front-end yields may consolidate, and the Nikkei could receive support from reduced concerns about immediate tightening.
