South Korea’s foreign exchange reserves declined slightly in September 2026, easing to $440.56 billion from $442.28 billion in August, according to data updated on 5 October 2026. The modest drop underscores ongoing adjustments in reserve levels after holding above the $440 billion mark.
The movement from August’s $442.28 billion to September’s $440.56 billion suggests a marginal drawdown, which may reflect currency market operations, valuation effects, or a combination of both. While still substantial by global standards, the latest reading indicates a small step down in the country’s external buffer over the month.
