Recent South Korean consumer price data, with September 2026 CPI inflation at 2.9% year-over-year after August’s 3.1% print, has kept the 3.0%+ and 2.7–2.9% annual outcomes nearly tied in trader pricing. Elevated energy costs from Middle East tensions, a weaker won, and broadening core pressures—driven by semiconductor-led demand, airfares, and durable goods—support the higher bracket, while base effects and moderating food prices cap upside. The Bank of Korea has signaled October inflation will remain near 3%, with cost and demand spillovers likely persisting. October CPI and subsequent releases through year-end will serve as key swing factors for the full-year 2026 outcome.
