SEOUL, SOUTH KOREA / RankWire.AI / – In August, South Korea’s foreign exchange reserves experienced their largest monthly rise ever, reaching a total of $442.28 billion by month’s end, according to the Bank of Korea. This marked a $14.33 billion jump from $427.95 billion at the close of July, representing the biggest monthly increase since the reserve data series began in 1971. The total also marked the highest level since May 2022.

The August surge continued 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 was significantly larger, surpassing even the previous record monthly rise of $14.29 billion set in May 2009. Despite this remarkable growth, reserves still remain below the record $469.21 billion reported in October 2021.
The central bank attributed the boost to various quantifiable factors during August. Foreign currency deposits held by financial institutions saw growth throughout the month. Additionally, returns on reserve assets contributed to the overall increase. Currency fluctuations also played a role, elevating the dollar value of assets denominated in other currencies. Since the Bank of Korea values the country’s reserves in U.S. dollars, changes in exchange rates can influence their reported worth without altering the actual amount of foreign assets held.
Foreign securities continue to form the largest part of reserves
By the end of August, foreign securities made up the majority of South Korea’s foreign exchange reserves, with a value increase of $7.07 billion from July to $387.07 billion. This accounted for 87.5% of the nation’s total reserve holdings. This category includes both government and corporate securities held as part of reserve assets. Foreign currency deposits also saw substantial growth, climbing by $7.17 billion during August to reach $30.30 billion at month’s end.
Special drawing rights rose by $60 million to $15.77 billion in August. South Korea’s reserve position was approximately $4.34 billion, while gold holdings remained steady at $4.79 billion. The data indicates that securities still dominate the reserve composition despite the notable rise in deposits. The combined increase in securities and foreign currency deposits accounts for nearly all of the $14.33 billion monthly growth in the country’s official foreign reserves.
August’s boost elevates reserves to a four-year peak
The reserve total of $442.28 billion marks the highest level in over four years. South Korea last reported a higher reserve in May 2022, when the total was $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 encompass securities, deposits, gold, special drawing rights, and the country’s reserve position within the international monetary system.
Foreign exchange reserves serve as an essential pool of foreign currency assets that support international transactions and external financial commitments. South Korea reports these figures monthly, providing markets with a consistent gauge of the nation’s reserve status. August’s record monthly increase and highest overall balance since May 2022 highlight a significant shift from the modest gains recorded in June and July, although the total still remains below the historical peak.
