FX.co ★ South Korea’s October CPI Eases to 2.8% YoY, Slightly Below September Reading

South Korea’s consumer price inflation edged down in October 2026, with the Consumer Price Index (CPI) rising 2.8% year-over-year, compared with a 2.9% increase recorded in September 2026. The figures, updated on 2 November 2026, confirm a modest easing in price pressures on an annual basis.

Both the current and previous readings reflect year-over-year changes, meaning October’s 2.8% rate measures price growth relative to October of the prior year, while September’s 2.9% figure compares prices to September a year earlier. The slight downtick suggests inflation is stabilizing, though it remains closely watched by policymakers and markets assessing the trajectory of South Korea’s price dynamics.
