Bank of Korea sold net $800 million for FX intervention in Q2

South Korea's foreign exchange authorities sold a net $800 million in currency market intervention during Q2, following $2.96 billion in Q1, marking the third consecutive quarter of dollar sales to curb won depreciation. This intervention coincided with an 8.7% strengthening of the won against the dollar in Q2, its largest quarterly gain since late 2022, also supported by a 7.1% decline in the broader dollar index.

Analysis

South Korea's foreign exchange authorities scaled back their market intervention in the second quarter, selling a net $800 million to support the won, a significant reduction from the $2.96 billion sold in the first quarter. This marks the third consecutive quarter of dollar sales aimed at curbing the won's depreciation. The reduced intervention coincided with a period of significant strength for the local currency, which appreciated 8.7% against the U.S. dollar in Q2—its largest quarterly gain since the final quarter of 2022. This rebound followed a period where the won had touched its weakest level since 2009. A crucial contributing factor was the broader market environment, as the U.S. dollar index concurrently fell by 7.1%. This suggests that the won's recovery was driven by a combination of targeted, but less aggressive, central bank support and a significant tailwind from general dollar weakness, lessening the pressure on Korean authorities to deplete reserves.

Key Decisions for Investors

• Investors should note that the won's 8.7% Q2 rally was heavily dependent on the 7.1% drop in the broader dollar index, not just the central bank's intervention; a reversal in the dollar's trend could quickly renew pressure on the KRW.
• The significant reduction in intervention size, from $2.96 billion in Q1 to $800 million in Q2, indicates that external conditions eased the burden on the Bank of Korea, but investors should monitor for any re-acceleration of dollar sales as a signal of renewed currency stress.
• For those with exposure to South Korean equities, the won's stabilization is a positive catalyst for dollar-denominated returns, but positions should be managed with an awareness of the high correlation to the global U.S. dollar cycle.
