Yesterday's Recap

South Korean equities closed mixed despite broad semiconductor strength. The KOSPI finished at 6,471.17, down 5.80% on the session, while the KOSDAQ slipped 1.17% to 824.46. Samsung rose 9.49% to 271,000 won and SK Hynix jumped 12.73% to 1,691,000 won, reflecting continued AI-driven demand for memory chips.

The won strengthened markedly, with USD/KRW dropping to 1,393.81. Korea’s long-term government bond yield rose 2.60% to 4.18% while the short-term rate held steady at 2.54%. News flow highlighted KDI’s upward revision of 2026 GDP growth to 3.2%, citing the chip export boom, alongside the central bank’s appointment of Kwon Min-soo to bolster international finance expertise.

Equity market gains prompted a historic contraction in the net international investment position.

The Day Ahead

Markets enter a data-light session with no major Korean releases scheduled. Attention will remain on follow-through in semiconductor names after yesterday’s outsized moves in Samsung and SK Hynix. Currency traders will monitor whether the won’s break below 1,400 sustains or invites intervention signals from authorities.

Global equity futures and U.S. Treasury yields will set the tone for risk sentiment into the Asian open. Any comments from the newly appointed deputy governor Kwon could provide early clues on foreign-exchange policy priorities.

Other Economic Notes

KDI’s 3.2% growth forecast exceeds the government’s 3.0% projection and underscores the narrow but powerful contribution of AI chip exports to the Korean economy. External asset data showed a historic contraction in net international investment position as equity market gains prompted valuation adjustments. Deposit insurance fee increases of 910 billion won annually will raise funding costs for banks, potentially feeding into lending spreads.

Financial crime losses at major banks reached a decade high, highlighting ongoing governance risks in the sector.

Global Macro News

Brent crude advanced 1.71% to 93.19 dollars while gold climbed 1.92% to 4,575.50, reflecting persistent safe-haven demand. Bitcoin rose 4.75% to 72,555.74, adding to risk-on sentiment in digital assets. Regional equity markets in Japan also rebounded, with Kioxia gaining more than 6%.

MUFG analysts noted that Korean tech outperformance is supporting the won against a basket of Asian currencies. Lower financing costs for leveraged bets on SK Hynix shares signal improving foreign-investor access to Korean equities.

BoK Watch

The appointment of international finance specialist Kwon Min-soo as senior deputy governor signals the Bank of Korea’s intent to strengthen foreign-exchange surveillance at a time of rapid won appreciation. Recent statements indicate the committee remains focused on the balance between easing inflation pressures and financial-stability risks arising from currency volatility. With CPI at 2.79% year-over-year as of July, price pressures have moderated, yet the won’s move below 1,400 complicates the timing of any further policy adjustment.

Officials have reiterated that rate decisions will hinge on incoming data and external conditions rather than preset calendars. Markets now price a higher probability of an extended hold as the central bank weighs the growth impulse from chip exports against potential capital-flow reversals.
