UBS Slashes KOSPI Forecast to 8,000 Amid Rising Rates and Surging Oil Costs

Key Takeaways

• UBS reduced its KOSPI 12-month forecast to 8,000 from 8,800, representing a reduction of almost 10%
• Elevated interest rates, Korean won appreciation, and crude oil exceeding $100 per barrel are key headwinds
• Analyst consensus for earnings-per-share revisions shifted negative in September for the first time in 2025
• Despite the cut, UBS projects robust KOSPI earnings expansion of 256% in 2026 and 38% in 2027
• Samsung Electronics and SK Hynix advanced following gains in a major US chip sector indicator

UBS has reduced its 12-month forecast for South Korea’s benchmark KOSPI index to 8,000, down from its previous 8,800 projection. The revision, representing a decline of roughly 10%, acknowledges intensifying challenges from elevated borrowing costs, currency appreciation, and climbing crude oil valuations.

Strategist Yong-Suk Son detailed the revision in research released Friday. The analyst reduced the projected earnings multiple to 7x from 8x, pointing to escalating macroeconomic challenges despite continued strength in corporate profit growth.

A significant development is the shift in consensus earnings-per-share revisions, which declined 0.7% on a monthly basis in September after maintaining positive momentum throughout the earlier part of the year. The memory semiconductor sector upgrades that previously fueled index advancement have now experienced reversals.

Notwithstanding the reduced target, UBS maintains optimistic projections for KOSPI earnings-per-share expansion of 256% in 2026 and 38% in 2027. Son indicated the index may experience range-bound trading until third and fourth quarter reporting periods provide additional confirmation on whether these profit expectations remain achievable.

Monetary Tightening and Energy Costs Drive Yield Expansion

South Korea’s central bank has implemented two rate increases since July. The 10-year sovereign bond yield has surged to 4.5% from 3.4% at year-start. Crude oil is currently trading above the $100 per barrel threshold, compounding inflationary pressures.

Currency appreciation represents an additional headwind. UBS calculates that each 1% strengthening of the won results in approximately 1.1% erosion in KOSPI corporate earnings.

The investment bank established an optimistic KOSPI scenario of 9,200 and a pessimistic target of 5,100, creating a substantial range that underscores current market uncertainty.

Regarding sector positioning, UBS maintains its preference for memory semiconductor exposure. The firm identifies Samsung Electronics and SK Hynix as leading investment opportunities. Nevertheless, the bank is rotating toward value-oriented and quality stocks offering shareholder distributions, acknowledging decelerating market momentum and constrained liquidity conditions.

Regional Equity Markets and Semiconductor Stocks Advance

In parallel developments, Asian equity and fixed income markets registered modest gains Friday as petroleum prices retreated. Brent crude decreased 0.8% to approximately $104 per barrel, alleviating some inflation anxieties.

Samsung Electronics and SK Hynix both posted gains following a rally in a prominent US semiconductor benchmark. US markets delivered their strongest performance since August in the previous session, recovering from declines that followed the Federal Reserve’s initial rate increase since 2023.

The 10-year US Treasury yield declined nine basis points to 4.93% as energy prices moderated. The yield had reached 5.02% earlier in the week following the Fed’s policy action.

MSCI’s Asia-Pacific equity benchmark advanced 0.5%, although declining issues outnumbered advancing ones, indicating the rally lacked broad market participation.

Reduced energy costs may provide monetary authorities with additional flexibility to evaluate the effects of restrictive policy measures, potentially offering near-term support for both equity and bond markets.
