SEOUL, SOUTH KOREA / RankWire.AI / – South Korea’s foreign exchange reserves experienced their most significant monthly growth on record in August. By the end of the month, reserves reached $442.28 billion, according to the Bank of Korea. This marked an increase of $14.33 billion compared to $427.95 billion at the close of July. The rise in August was the largest since the reserve data series was first compiled in 1971 and also represented the highest level since May 2022.

This surge in August continues 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 gain exceeded these figures significantly and also surpassed the previous record monthly rise of $14.29 billion set in May 2009. Despite this impressive growth, reserves are still below the peak of $469.21 billion recorded in October 2021.
The Bank of Korea attributed the boost to several quantifiable factors in August. Foreign currency deposits held by financial institutions saw an uptick, and returns on reserve assets contributed further to the total. Currency movements also played a role, increasing the dollar value of assets denominated in other currencies. Since the Bank of Korea measures the country’s reserve holdings in U.S. dollars, fluctuations in exchange rates can influence their reported value without affecting the actual amount of foreign assets.
Foreign securities remain the main component of reserves
At the end of August, foreign securities made up the majority of South Korea’s foreign exchange reserves. Their value climbed by $7.07 billion from July to reach $387.07 billion, accounting for 87.5% of the total reserve holdings. This category includes government and corporate securities held as reserve assets. Foreign currency deposits also saw substantial growth, rising by $7.17 billion during August to close at $30.30 billion.
Special drawing rights increased by $60 million, reaching $15.77 billion in August. South Korea’s reserve position was approximately $4.34 billion, and gold holdings remained steady at $4.79 billion. Despite the notable increase in deposits, securities continued to comprise the dominant share of the reserve portfolio. The combined growth of securities and foreign currency deposits essentially accounted for the entire $14.33 billion increase in the official foreign reserves for August.
Reserves hit four-year high with August boost
The reserve total of $442.28 billion marked the highest level in over four years, since May 2022 when reserves reached $447.71 billion. This latest figure also indicates a move closer to pre-decline levels following the October 2021 peak. South Korea’s 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 a crucial pool of foreign currency assets that support external payments and financial commitments. The monthly reporting of these figures offers markets a regular gauge of South Korea’s reserve situation. August’s data not only set a new monthly record but also represented the highest overall balance since May 2022. This marks a significant shift from the smaller reserve gains observed in June and July, although the total remains below the country’s historical peak.
