Recent South Korean consumer price data, with the September 2026 year-over-year rate at 2.9% after August’s 3.1%, combined with Bank of Korea projections of 2.7% annual inflation, underpin the narrow lead for the 2.7–2.9% outcome. Persistent cost pressures from elevated petroleum prices amid Middle East tensions and demand-pull effects from robust semiconductor and AI-driven growth have kept core inflation near 2.8% and prompted consecutive rate hikes to 3.00%. October readings are expected near 3%, while the central bank maintains a restrictive stance to anchor expectations above its 2% target. Traders weigh these factors against potential moderation from won stability and any further policy tightening ahead of year-end data releases.
