Yesterday's Recap

Korean equities opened lower and extended losses through the session, with the KOSPI closing down 2.62% at 6,625.93 and the KOSDAQ shedding a more modest 0.69% to 892.27. The decline came despite Samsung Electronics reporting record earnings, with headlines flagging record results driven by surging AI chip demand. Samsung shares fell 2.42% to 262,000 won and SK Hynix dropped 2.44% to 1,681,000 won, suggesting profit-taking dominated the tape after a strong run.

Fixed income told a different story: the 10-year government yield eased 8 bp to 4.31% and the 3-year fell 6 bp to 3.92%, a bull-steepening pattern consistent with rate-cut expectations firming. The won appreciated 0.68% against the dollar to 1,333.89, supported by the bond rally and foreign inflows. In the commodity complex, Brent crude climbed 1.25% to $106.03 on supply concerns tied to Middle East geopolitical risks, a headwind for Korea's energy-import-heavy economy.

Gold slipped 0.49% to $4,195.80 and Bitcoin retreated 1.10% to $82,757.92, reflecting a broader risk-off tone in alternative assets.

The Day Ahead

Thursday's headline unemployment rate release at 19:00 ET is the key domestic data point this week, with the previous reading at 2.7% and no consensus available. Labor market resilience has been a pillar of the domestic demand story, and any deterioration would add weight to the case for further BoK accommodation. Governor Rhee Hyun-song travels to Bangkok this week for the G20 Finance Ministers and Central Bank Governors meeting alongside IMF-World Bank sessions, offering a platform for signaling on the policy path.

Markets will also parse any commentary from the IMF meetings for clues on the BoK's stance following last week's hold. With no other tier-one releases scheduled, attention shifts to semiconductor earnings follow-through and the trajectory of foreign portfolio flows into Korean equities. Watch for follow-through selling in large-cap tech if US peers soften overnight.

Other Economic Notes

Korea's inflation picture remains anchored near target, with CPI running at 2.88% year-on-year as of September, keeping the BoK's price stability mandate comfortable but not complacent. ↓ p.2

Other Economic Notes (continued)

The semiconductor boom is spilling into the broader economy, with Samsung and SK Hynix's record earnings fueling corporate spending on AI infrastructure and youth employment initiatives. Secondary battery ETFs have surged on AI data center demand, highlighting the equity market's concentration in a narrow set of themes. On the structural front, Jeonbuk Bank launched Korea's first Bitcoin-backed won loan for corporate clients, signaling gradual institutionalization of digital assets in the banking system.

Meanwhile, hacking attempts on the Bank of Korea and state lenders exceeded one million last year, underscoring cybersecurity as an operational priority for financial authorities.

Global Macro News

Global central banks are trimming dollar reserves, a shift that Seoul Economic Daily notes could open the door for greater internationalization of the won — a long-standing policy goal with implications for Korea's external sector resilience. Oil's advance to $106.03 on Brent complicates the inflation outlook for Asian importers, Korea included, where energy is the largest single import category. The AI capex supercycle remains the dominant equity narrative, with Samsung's record profit and SK Hynix's momentum tied directly to hyperscaler memory orders; any deceleration in US AI spending would transmit quickly to Korean large-caps.

Bitcoin's pullback to $82,757.92 and gold's dip suggest a pause in the alternative-asset rally that has paralleled the tech run. ↓ p.3

Continuation

Global Macro News (continued)

The G20 and IMF meetings in Bangkok this week will frame the global policy backdrop, with markets watching for coordination signals on currencies and growth support. For Korea, the interplay of a firming won, rising oil, and concentrated tech earnings sets a delicate near-term balance.

BoK Watch

Governor Rhee Hyun-song's appearance at the G20 and IMF-World Bank meetings in Bangkok comes at a sensitive moment, with the base rate at 2.81% following the August decision. Notably, the governor publicly apologized over ETF-related risks while simultaneously leaving the door open to further rate hikes — a dual message that acknowledges financial stability concerns in the fund market without committing to a tightening bias. The bond market's rally, with the 10-year yield down 8 bp to 4.31%, suggests investors currently price a benign path, though the 3-year at 3.92% remains well above the policy rate, implying the market still embeds normalization risk.

With CPI at 2.88% year-on-year, inflation sits close to target, giving the board latitude to prioritize growth and financial stability considerations. The record returns on foreign asset management — nearly $12.5 billion in 2025 — highlight the BoK's substantial reserve portfolio and its role in smoothing won volatility. Rhee's Bangkok platform offers an opportunity to frame the external balance of payments story and the won internationalization agenda.

Markets should watch for any nuance in his public remarks that departs from the recent hold stance, particularly on the timing of the next move given the ETF stability overhang.
