SEOUL, SOUTH KOREA / RankWire.AI / – In August, South Korea’s foreign exchange reserves experienced their largest monthly rise on record, reaching a total of $442.28 billion by month’s end, according to the Bank of Korea. This marks an increase of $14.33 billion compared to $427.95 billion at the close of July. The August jump is the most significant since the data series began in 1971, and the total is now at its highest level since May 2022.

The growth in August signifies a third consecutive month of recovery in South Korea’s foreign reserves. Reserves increased by $370 million in June and by $590 million in July. However, the August figure surpasses both previous gains, including the previous record monthly increase of $14.29 billion set in May 2009. Despite this substantial rise, reserves remain below the peak of $469.21 billion recorded in October 2021.
The central bank attributed the August expansion to several quantifiable factors. During the month, foreign currency deposits held by financial institutions expanded, while returns on reserve assets contributed further. Movements in currency exchange rates also elevated the dollar value of assets denominated in other currencies. As the Bank of Korea values the country’s reserves in U.S. dollars, fluctuations in exchange rates can modify reported values without altering the actual amount of foreign assets.
Foreign securities dominate the reserve composition
Foreign securities constituted the largest component of South Korea’s foreign exchange reserves at the end of August. Their valuation increased by $7.07 billion from July, reaching $387.07 billion, which accounts for 87.5% of the total reserves. This category includes government and corporate securities held as reserve assets. Additionally, foreign currency deposits saw another sizable rise, climbing by $7.17 billion during August to $30.30 billion by month’s end.
Special drawing rights grew by $60 million, reaching $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 continue to form the core of the reserve portfolio despite the significant increase in deposits. The combined expansion of securities and foreign currency deposits accounted for nearly all of the $14.33 billion rise in the country’s official foreign reserves during August.
Reserves hit four-year high with August’s increase
The reserve total of $442.28 billion marked the highest level in over four years. The last time South Korea reported a higher total was in May 2022, when reserves stood at $447.71 billion. This recent figure brings the nation closer to the levels seen before the decline that followed the October 2021 peak. Official foreign reserves encompass securities, deposits, gold, special drawing rights, and the country’s reserve position in the international monetary system.
Foreign exchange reserves serve as official assets in foreign currencies, supporting international transactions and external financial commitments. South Korea provides monthly updates on these figures, offering the markets a regular indicator of its reserve status. August’s record monthly increase and peak overall balance since May 2022 highlight a significant change from the modest gains in June and July, although the reserves remain below South Korea’s historical maximum.
