SEOUL, SOUTH KOREA / RankWire.AI / – In August, South Korea’s foreign exchange reserves experienced their largest monthly increase ever. The Bank of Korea announced that reserves rose to $442.28 billion by the end of the month. This marks a $14.33 billion rise from $427.95 billion at the close of July. It is the biggest monthly increase recorded since the start of the reserve data series in 1971. The total reserves also reached their highest point since May 2022.

The surge in August continues a three-month upward trend in South Korea’s foreign reserves. After an increase of $370 million in June and $590 million in July, the August gain significantly exceeded these figures. It also outpaced the previous record monthly rise of $14.29 billion, set in May 2009. Despite this substantial growth, reserves remain below the peak of $469.21 billion reported in October 2021.
The central bank attributed the increase to several quantifiable factors during August. Financial institutions held higher amounts of foreign currency deposits. Returns from reserve assets also contributed to the total. Currency fluctuations increased the dollar value of assets denominated in other currencies. Since the Bank of Korea measures reserves in U.S. dollars, exchange rate movements can change their reported value without affecting the actual quantity of foreign assets.
Foreign securities continue to comprise the largest portion of reserves
Foreign securities made up the majority of South Korea’s foreign exchange reserves at the end of August. Their value grew by $7.07 billion from July, reaching $387.07 billion. This accounted for 87.5% of the total reserve holdings. The category includes government and corporate securities kept as reserve assets. Foreign currency deposits saw another significant increase, climbing by $7.17 billion in August to end the month at $30.30 billion.
Special drawing rights added $60 million, reaching $15.77 billion during August. South Korea’s reserve position was about $4.34 billion, while gold holdings remained unchanged at $4.79 billion. The data indicates that securities continue to dominate the reserve portfolio despite the substantial rise in deposits. The combined growth of securities and foreign currency deposits accounted for nearly all of the $14.33 billion increase in the country’s official foreign reserves for the month.
Reserves in August reach four-year high, surpassing previous peaks
The reserve total of $442.28 billion marked the highest level in over four years. South Korea last reported a higher figure in May 2022, when reserves reached $447.71 billion. These latest figures also bring the country closer to levels seen before the decline following the October 2021 peak. Official foreign reserves include securities, deposits, gold, special drawing rights, and the nation’s reserve position within the international monetary system.
Foreign exchange reserves are vital for supporting international transactions and meeting external financial obligations. The South Korean government reports these figures monthly, providing a consistent indicator of the country’s reserve status. August’s record monthly increase and the highest overall reserve balance since May 2022 stand out. The recent data signals a notable rebound from the smaller reserve gains in June and July, although the total remains below South Korea’s historical maximum.
