Recent September 2026 CPI data showed South Korea’s headline inflation easing to 2.9% year-over-year from 3.1% in August, with core measures at 2.8%, as softer agricultural prices and fuel caps offset elevated energy costs tied to Middle East tensions. Trader sentiment remains closely balanced between the 2.7–2.9% and 3.0%+ annual outcomes because ongoing pass-through from petroleum and semiconductor-driven demand, alongside robust export-led growth, continues to support readings near or above 3%. The Bank of Korea’s base rate at 3.00% after consecutive hikes, combined with Governor comments emphasizing restrictive policy while inflation stays above the 2% target, reinforces expectations of limited near-term moderation. October CPI and the October 22 Monetary Policy Board meeting represent key near-term catalysts that could shift the market-implied odds.
