CADKRW Slides 10.6% as Korean Rate Hike and Export Surge Outpace Canadian Monetary Stance

The CADKRW pair has fallen -10.6% over the past three months, reflecting a sharper appreciation of the South Korean won versus a weakening Canadian dollar. The primary driver is the Bank of Korea’s recent policy‑rate increase combined with a record‑size semiconductor export boom, while the Bank of Canada has kept its policy rate unchanged at 2.25% amid elevated inflation.

Rate Divergence Fuels KRW Strength

The Bank of Korea raised its base rate by 25 bp to 3.00 % on 27 August 2026, marking the second consecutive hike. This move widened the interest‑rate differential with Canada, where the Bank of Canada left its overnight target unchanged at 2.25 % on 2 September 2026. The resulting differential of roughly 0.75 percentage points has made the won more attractive to carry‑trade investors, supporting its appreciation against the CAD.

Korean Export Boom Adds Demand for Won

During the first 20 days of September 2026, South Korea exported a record $34.12 billion worth of semiconductors – a 259 % year‑on‑year increase. Semiconductor shipments accounted for roughly 48 % of total exports, pushing overall outbound shipments to $71.4 billion. The surge, driven by strong global demand for AI‑related chips, has boosted won‑denominated cash flows and reinforced the currency’s upward momentum.

Canadian Inflation, Oil Prices and Trade Tensions Weigh on CAD

Canada’s headline CPI remains near 3 %, largely because of persistently high gasoline prices linked to the ongoing Middle‑East conflict. The Bank of Canada warned that “upside inflation risks have increased,” citing energy‑price spill‑overs and new U.S. tariffs on Canadian exports. The retaliatory tariffs imposed on U.S. imports worth C$27.6 billion – ranging from 15 % to 50 % – have added cost pressures and dampened confidence in the Canadian economy. With the policy rate held steady, the CAD lacks the monetary‑policy support that the won now enjoys.

Risk Outlook

The CADKRW trajectory will hinge on three variables: (1) any shift in the Bank of Canada’s policy stance – a premature rate hike could narrow the differential and support the CAD; (2) the evolution of oil prices – a sustained decline would ease Canadian inflation and improve the currency’s outlook; and (3) the durability of Korea’s export momentum – a slowdown in semiconductor demand or a pause in BoK tightening could reverse won gains. Upcoming data releases, including Canada’s October 2026 inflation report and the Bank of Canada’s next policy decision on 28 October 2026, will be closely watched for clues on whether the current pricing of a weaker CAD relative to the KRW remains justified.
