SEOUL, SOUTH KOREA / RankWire.AI / – In August, South Korea’s foreign exchange reserves experienced their largest monthly growth on record. The Bank of Korea announced that reserves reached $442.28 billion at the end of the month, reflecting a $14.33 billion rise from $427.95 billion in July. This surge marked the most significant monthly increase since the reserve data series started in 1971 and also brought the total to its highest level since May 2022.

The boost in August continues a three-month upward trend in South Korea’s foreign reserves. After rising by $370 million in June and $590 million in July, the reserve increase in August far exceeded these figures. It also beat the previous record monthly increase of $14.29 billion, set in May 2009. Despite this substantial gain, reserves remained below the $469.21 billion peak recorded in October 2021.
The central bank attributed this growth to several quantifiable factors during August. Financial institutions increased their holdings of foreign currency deposits, and returns on reserve assets contributed further to the overall rise. Currency fluctuations caused the dollar value of assets in other currencies to grow, as the Bank of Korea values the country’s reserves in U.S. dollars. Therefore, exchange rate movements can influence the reported value without affecting the actual amount of foreign assets.
Foreign securities continue to constitute the largest component of reserves
At the end of August, foreign securities made up the majority of South Korea’s foreign exchange reserves. Their value grew by $7.07 billion from July, reaching $387.07 billion. This accounted for 87.5% of the total reserve holdings. This category encompasses government and corporate securities held as reserve assets. Foreign currency deposits also experienced a significant increase, climbing by $7.17 billion during August to total $30.30 billion at month’s end.
Special drawing rights saw an increase of $60 million, reaching $15.77 billion, while South Korea’s reserve position stood at approximately $4.34 billion. Gold holdings remained unchanged at $4.79 billion. The composition indicates that securities continued to dominate the reserve portfolio despite the notable rise in deposits. The combined increase in securities and foreign currency deposits accounted for nearly all of the $14.33 billion monthly rise in the nation’s official foreign reserves.
August’s increase pushes reserves to a four-year high
The reserve balance of $442.28 billion marked the highest level in over four years. South Korea last reported a higher total in May 2022, when reserves amounted to $447.71 billion. These latest figures also bring the country closer to the levels seen before the decline following the October 2021 peak. Official foreign reserves comprise securities, deposits, gold, special drawing rights, and the country’s reserve position within the international monetary system.
Foreign exchange reserves serve as the official authorities’ stock of foreign currency assets, supporting international payments and external financial commitments. South Korea releases these figures monthly, providing markets with a regular indicator of the country’s reserve status. August’s data not only showed a record monthly increase but also represented the highest overall reserve balance since May 2022. This marks a significant shift from the smaller reserve gains observed in June and July, although the total remains below South Korea’s historical peak.
