KRW/SEK Climbs 16.7% as Korean Rate Hikes Outpace Swedish Policy
September 19, 2026
The KRW/SEK spot pair has risen 16.7% over the past three months, the steepest gain among major Asian currencies. The rally is anchored in the Bank of Korea’s (BoK) back‑to‑back rate hikes, which have widened the interest‑rate differential versus the Swedish krona.
Rate Differentials Drive KRW Strength
The BoK raised its benchmark policy rate by 25 bps to 2.75 % on 16 July 2026 – its first increase since January 2023 – and followed with a second 25‑bp hike on 26 August, taking the rate to 3.00 %. By contrast, Sweden’s Riksbank kept its policy rate unchanged at 1.75 % throughout May‑August 2026. The widening gap of roughly 1.25 percentage points has made the won more attractive to short‑term capital flows, reinforcing the currency’s upward trajectory.
Export Boom Underpins Korean Growth Outlook
A surge in export activity has bolstered the BoK’s growth forecast to 3.3 % for 2026. In August, total goods exports reached $98.25 billion, up 68.7 % YoY, with semiconductor shipments exploding by 209 % YoY to $46.65 billion. The AI‑driven chip boom, together with record‑high computer and wireless‑device exports, provides a solid macro backdrop for the won, even as core inflation rose to 3.4 % in August.
Swedish Policy Stance Limits SEK Upside
The Riksbank’s decision to hold rates at 1.75 % reflects a “wait‑and‑see” approach amid mixed inflation signals. With no immediate tightening, the krona has lacked the rate‑driven support that the won enjoys, contributing to its relative weakness against the won.
Risks and Upcoming Catalysts
The KRW/SEK rally could be challenged by any pause in BoK tightening or a sharper than‑expected slowdown in semiconductor demand. Market participants will watch the BoK’s September policy‑rate decision (scheduled for 10 September 2026) for clues on future hikes. On the Swedish side, a surprise rate increase by the Riksbank would narrow the differential and could halt the SEK’s depreciation. Additionally, global oil‑price volatility stemming from the Middle‑East conflict remains a wildcard for both economies.
