South Korea's foreign exchange reserves increased to $422 billion in September 2025, up from $416.3 billion in August. The increase was driven by higher securities holdings, which climbed to $378.4 billion from $366.2 billion. Meanwhile, Special Drawing Rights (SDRs) remained steady at $15.8 billion, gold reserves held at $4.8 billion, and the IMF reserve position stayed at $4.5 billion. On the other hand, deposits declined to $18.5 billion from $25 billion.
