South Korea's foreign exchange reserves increased in June, reaching US$427.36 billion, according to data released by the Bank of Korea on Friday.

The rise occurred even as authorities implemented measures to manage exchange rate volatility, suggesting that underlying capital flows and valuation effects supported the buffer despite intervention efforts.

The central bank's disclosure highlights the resilience of South Korea's external position amid ongoing market turbulence.

While the specific magnitude of the monthly change was not detailed in the initial report, the total level remains robust, providing a cushion against potential external shocks.

This development comes as policymakers balance the need for currency stability with the desire to maintain ample reserve levels for financial security.

The reserve build-up aligns with broader positive economic indicators in South Korea.
