Today's Economic Events

Data Prior Cons Time
No events available
  • Exports jumped 83.5% y/y, beating consensus by a wide margin and lifting external demand outlook.

Yesterday's Recap

South Korea’s September exports surged 83.5% y/y, well above the 61.7% consensus and prior 68.7%, signaling robust semiconductor and global demand. The S&P Global Manufacturing PMI climbed to 53.9 from 52.3, confirming expansion in factory activity. Consumer prices rose 2.9% y/y, matching forecasts and easing from 3.1% in August, while business confidence slipped to 79 from 81.

Equity markets responded positively, with the KOSPI advancing 0.46% to 7,003.74 on bargain hunting in technology names and SK Hynix gaining 0.44%. The won strengthened sharply as USD/KRW fell 1.27% to 1,343.34. The Korea 10-year government yield rose 3 bp to 4.44% while the 3-year yield held steady at 4.01%.

Samsung shares closed unchanged at 276,000.

The Day Ahead

No major economic releases or Bank of Korea events are scheduled for 4 October, leaving markets to digest yesterday’s data. Focus will remain on follow-through in the won and KOSPI after the export surprise and inflation print. Participants will monitor any further comments from officials on underlying price pressures ahead of the next policy meeting.

Global risk sentiment and U.S. Treasury moves may continue to influence local yields and currency flows. Semiconductor supply-chain updates could also affect SK Hynix and Samsung performance.

Traders will watch for any signs of sustained won strength prompting additional Bank of Korea intervention.

Other Economic Notes

M&A activity reached 62 trillion won in the first nine months, already exceeding the full-year 2025 total and underscoring corporate restructuring momentum. High-rate mortgage shares at the big-five banks have risen sharply, raising household debt-service concerns amid still-elevated borrowing costs. The Bank of Korea noted that underlying price pressures are building even as headline inflation moderated, keeping October readings near 3%.

These developments highlight the tension between export-led growth and domestic financial-stability risks. Strong external demand continues to support the current-account position despite softer business sentiment.

Global Macro News

U.S. Treasury yields approached 5% despite pivot speculation, increasing pressure on Korean lending rates and capital-flow dynamics. The Bank of Korea sold $9.6 billion to support the won, illustrating active management of exchange-rate volatility linked to global rate differentials.

Asian equity markets showed mixed performance, with Seoul shares benefiting from local tech buying amid broader uncertainty. Brent crude held near 102.25 while gold declined 0.95%, reflecting shifting safe-haven demand that could affect Korean import costs. Korean investors have increased overseas property allocations as the won strengthened, diversifying away from domestic assets.

Global semiconductor demand remains supportive for Korea’s export sector, though any U.S. or Chinese policy shifts could alter the trajectory. The combination of firmer U.S.

yields and resilient Korean data keeps external financing conditions in focus for policymakers.

BoK Watch

The Bank of Korea stated that September inflation at 2.9% masks building underlying price pressures and that October readings should stay near 3%. With the base rate at 2.81%, the committee voted to hold, citing the need to monitor persistent core trends before any adjustment. Minutes and recent communications emphasize financial-stability risks from rapid mortgage-rate repricing alongside export resilience.

Continuation

BoK Watch (continued)

Markets have priced steady policy through year-end, consistent with the modest rise in the 10-year yield and the stronger won. Forward guidance continues to stress data dependence, particularly on inflation persistence and household credit growth. The combination of robust external demand and sticky domestic prices leaves little room for near-term easing signals.
