SEOUL, SOUTH KOREA / RankWire.AI / – South Korea’s foreign exchange reserves saw their largest monthly surge ever in August. By the end of the month, reserves totaled $442.28 billion, according to the Bank of Korea. This represented an increase of $14.33 billion from $427.95 billion at the close of July. The monthly growth was the largest since the reserve data series began in 1971 and marked the highest level since May 2022.

The August boost continued a three-month upward trend in South Korea’s foreign reserves, following increases of $370 million in June and $590 million in July. The August rise far exceeded either of those figures and also beat the previous record monthly increase of $14.29 billion set in May 2009. Despite this impressive growth, reserves still fell short of the all-time high of $469.21 billion recorded in October 2021.
The Bank of Korea attributed the rise to several quantifiable factors observed in August. An increase in foreign currency deposits held by financial institutions contributed to the overall. Additionally, returns on reserve assets managed by the central bank played a role in the growth. Fluctuations in currency exchange rates caused the dollar valuation of assets denominated in other currencies to rise. As the reserve holdings are measured in U.S. dollars, changes in the exchange rate can affect the reported value without altering the actual amount of foreign assets.
Foreign Securities Continue to Dominate Reserve Composition
Foreign securities made up most of South Korea’s foreign exchange reserves at the end of August. Their value rose by $7.07 billion from July, reaching $387.07 billion, accounting for 87.5% of total reserve assets. This category includes government and corporate securities held as part of the reserves. Foreign currency deposits experienced another significant increase, climbing by $7.17 billion during August to $30.30 billion at month’s end.
Special drawing rights grew by $60 million, reaching $15.77 billion. South Korea’s reserve position was approximately $4.34 billion, while gold holdings remained steady at $4.79 billion. Even with the substantial increase in deposits, securities continued to comprise the majority of the reserve portfolio. The combined growth of securities and foreign currency deposits accounted for nearly all of the $14.33 billion monthly rise in South Korea’s official foreign reserves.
Reserves Reach Four-Year Peak After August Increase
The $442.28 billion reserve level marked the highest total since May 2022, ending a period of over four years. The last time South Korea reported a higher reserve total was in May 2022, when the reserves stood at $447.71 billion. The latest figures also draw the country closer to the levels seen before the decline following the October 2021 peak. South Korea’s official foreign reserves encompass securities, deposits, gold, special drawing rights, and the country’s reserve position within the international monetary system.
Foreign exchange reserves serve as official assets in foreign currencies that support international transactions and external financial commitments. The country reports these figures monthly, providing markets with a regular update on its reserve position. The August report highlights both a record monthly increase and the highest overall reserve level since May 2022. This significant development contrasts with the smaller gains seen in June and July but remains below South Korea’s historic peak.
