📈 KOSPI surges 1.26% as SK Hynix breaks ground on ₩5.5T Indiana HBM fab; BoK raises rates for second straight month

Korean equities outperformed every regional peer Thursday with the iShares MSCI Korea ETF gaining 1.26%—the standout move in Asia—as SK Hynix's groundbreaking ceremony at its Indiana advanced-packaging HBM fab ($4 billion equivalent, ₩5.5 trillion) crystallised the stock's status as the premier AI-memory supply chain bet. Banks led sectoral gains at +0.42% (SHG +0.84%, KB +0.50%) while Industrials lagged at -2.61% (KEP -2.61%). The Bank of Korea delivered its second consecutive rate hike—'이제는 가래 대신 호미로 막은 것' (acting early rather than late, per BoK framing)—even as the government deploys an ₩800 trillion fiscal stimulus, creating a textbook monetary-fiscal policy mismatch. Nvidia's $96.2B Q2 result and $108B Q3 guide confirmed that SK Hynix's HBM bet is the right read; the Indiana fab positions Korea's flagship memory maker as Nvidia's US-domestic supply chain by 2029.

SK Hynix Indiana HBM fab groundbreaking: ₩5.5T, 2029 production target

SK Hynix broke ground at its West Lafayette, Indiana facility Thursday—an advanced-packaging HBM fab targeting ₩5.5 trillion ($4 billion) in capex, with 2028 completion and 2029 production start for annual output in the 'hundreds of thousands' of wafers. With Nvidia guiding $108B for Q3, the timing is near-perfect: SK Hynix will be the only HBM supplier with US-based production when the fab comes online, locking in strategic supply-chain relationships that Micron cannot match by 2029. The Indiana plant converts what was cornfields 18 months ago into the central node of AI memory supply for the US market—a signal of the depth of Samsung-SK Hynix-TSMC America's long-term capex cycle.

BoK raises rates twice in a row; fiscal-monetary mismatch is the key risk

The Bank of Korea hiked for the second consecutive meeting, framing the move as early-stage action ('호미') rather than belated firefighting ('가래'). The tension is real: BoK is tightening while the government is releasing ₩800 trillion in fiscal stimulus—a classic policy mismatch that historically widens KRW volatility and pressures household consumption. NIM (net interest margin) expansion from the rate hike is positive for KB Financial and Shinhan—their moves today (+0.50% and +0.84%) price in exactly this outcome.

Korean construction stocks surge on Iran-US truce possibility

Korean construction and engineering stocks spiked Thursday on reports of potential US-Iran ceasefire negotiations, with the sector pricing in a Middle East reconstruction trade. Korea's construction conglomerates (Samsung C&T, Hyundai E&C) have deep GCC contracting history and would be first-mover beneficiaries of any large-scale Iran reconstruction programme. This is a geopolitical optionality play: no commitment, but the CEF (construction-engineering-infrastructure) exposure to any post-Iran-war rebuild is structurally underpriced in KOSPI construction weights.

Smart-money note

The KOSPI's +1.26% outperformance against broad regional weakness is almost entirely SK Hynix-driven sentiment—the HBM memory story now has a US-soil production anchor that removes the geopolitical overhang. KB Financial (KB +0.50%) and Shinhan (SHG +0.84%) are pricing in NIM expansion from BoK's back-to-back hike—Korean bank earnings in a rising-rate environment expand mechanically on deposit repricing lags, and both names are well-positioned. KEP's -2.61% (Korea Electric Power) is the obvious rate-hike casualty: a utility with heavy debt load and regulated tariffs has zero pricing power to offset higher financing costs. Watch KRW most carefully: if USD strengthens materially post-Warsh, KRW weakens further and re-imports inflation in a vicious cycle that forces BoK to hike again—compressing consumer stocks (물가·환율·금리 '3高' as the Korean press is calling it) while banks paradoxically benefit.

What to watch tomorrow

SK Hynix KRX Gap-Up

Nvidia's $108B Q3 guide confirms sustained HBM demand; SK Hynix (000660.KS) should gap up significantly on Friday KRX open—the market consensus on HBM orders was already bullish and Nvidia has now raised the ceiling.

BoK Policy Statement Language

After two consecutive hikes, watch BoK's next statement for any hints on pause timing; the monetary-fiscal mismatch (₩800T stimulus vs. rate hikes) is unsustainable long-term and the market will search for the pivot signal.

Warsh KRW Impact

A hawkish Fed speech adds USD strength and further KRW pressure—worsening the triple-high (물가·환율·금리) burden for Korean consumers and adding to BoK's next-hike pressure; any KRW move past 1,400 to the USD is the threshold to watch.
