Korea and Japan extend $10B currency swap to 2029, reaffirming financial ties - CHOSUNBIZ - Chosunbiz

South Korea and Japan have agreed to extend their $10 billion currency swap arrangement through 2029, reaffirming a financial cooperation channel that dates back to the 2001 Chiang Mai Initiative. The facility allows each central bank to exchange its domestic currency for the other's, or for US dollars, up to the agreed limit.

For markets, the practical significance lies in the backstop it provides during periods of stress. A currency swap gives authorities a ready source of foreign-currency liquidity without needing to draw down reserves or sell assets into unsettled markets. That can help temper volatility in the won-yen exchange rate and reduce the risk of disorderly moves during risk-off episodes.

The extension is also a signal about the broader relationship. Currency swap lines tend to be renewed when both sides see value in keeping the channel open, so the 2029 horizon suggests a durable, if modest, commitment to financial dialogue. What to watch: whether the size is revisited, how often the facility is actually drawn, and whether it becomes part of wider regional liquidity discussions.
