South Korea's foreign exchange market saw unprecedented activity in the first quarter of 2026, with daily trading volumes hitting a record high since 2008.
This remarkable surge wasn't caused by a single factor, but rather a powerful combination of three distinct trends. First and foremost was the global AI supercycle. Strong earnings guidance from Korean tech giants like Samsung Electronics and SK hynix, fueled by soaring demand for AI memory chips, attracted a massive wave of foreign capital. International investors rushed to buy Korean stocks, which directly increased the volume of spot transactions as they converted their foreign currency into Korean won to make the purchases.
Second, a climate of heightened uncertainty drove a significant increase in hedging activity. The Korean won weakened past the psychological barrier of ₩1,500 per dollar for the first time in 17 years, while geopolitical tensions in the Middle East caused oil prices to spike. This volatility made businesses and investors nervous about future currency fluctuations. To protect themselves from potential losses, they increased their use of FX derivatives like forwards and swaps, which are instruments used to lock in an exchange rate for a future date. This defensive maneuver substantially boosted the derivatives portion of FX trading.
Finally, the market's fundamental structure was ready to handle this increased demand. Reforms implemented since 2024, which extended trading hours to 2 a.m. and allowed registered foreign institutions to participate directly in the onshore market, had already expanded the market's capacity and liquidity. This enhanced infrastructure acted as an amplifier, enabling the market to absorb the large inflows from equity investors and the increased hedging demand without friction. The phased inclusion into the FTSE World Government Bond Index (WGBI) also began, adding another source of steady capital inflow.
In essence, the record-breaking quarter was a perfect storm. The pull of the AI boom, the push from global volatility, and the expanded capacity of a reformed market all converged to create a new chapter for Korea's FX market.
