Japan: Goods Inflation Risks Remain Tilted to Upside - Societe Generale

In the latest Tokyo inflation data, food and energy price trends diverged, but the upside risk to overall goods inflation has not been resolved. Societe Generale economists Reo Sasaki and Shin Kanazaki noted in a report that October Tokyo CPI data showed food inflation continued to moderate, while oil-related goods inflation edged up, keeping inflation risks on the goods side tilted to the upside.

**Food Inflation Cooling Gradually**

As a key weight in Japan's core CPI, the narrowing of food price gains offers consumers some breathing room and, to a degree, corroborates earlier market expectations that cost-push inflation is gradually fading. However, SocGen economists stressed this does not mean overall inflationary pressure has clearly receded, as the trajectory of energy-related goods prices is emerging as a new variable.

**Energy Subsidy Effects and Oil Price Pass-Through**

With the government's reinstated energy subsidies continuing to weigh on the overall inflation reading through October, their statistical suppression effect may still mask some underlying price pressure in the near term. Yet the slight uptick in oil-related goods inflation indicates the transmission channel from international oil price swings to domestic prices remains intact—once the subsidy effect fades or global oil prices climb again, goods inflation faces a risk of re-accelerating.

**Implications for the Policy Outlook**

SocGen has previously noted that the structure of Tokyo inflation data will continue to support the Bank of Japan's hawkish-leaning stance. The current combination of easing food inflation and a modest rise in energy goods inflation precisely illustrates that inflation drivers are shifting from a single cost shock to a broader set of areas. For the BOJ, this means that in calibrating the pace of monetary policy normalization, greater attention should be paid to the potential upside risks in goods inflation, rather than focusing solely on the short-term headline rate distorted by subsidies.
