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

Key Points

• UBS reduced its 12-month forecast for the KOSPI index to 8,000 from 8,800, representing an almost 10% reduction
• Rising interest rates, an appreciating Korean won, and crude oil exceeding $100 per barrel are primary headwinds
• Earnings-per-share consensus revisions shifted into negative territory in September, marking the first decline this year
• The bank maintains expectations for robust KOSPI earnings expansion of 256% in 2026 and 38% in 2027
• Shares of Samsung Electronics and SK Hynix advanced following gains in a major US chip benchmark

Investment bank UBS has revised its 12-month forecast for South Korea’s KOSPI index downward to 8,000 from a previous estimate of 8,800. The adjustment, which represents nearly a 10% reduction, comes as the market faces mounting challenges from elevated borrowing costs, currency appreciation, and surging energy prices.

In a research note released on Friday, UBS analyst Yong-Suk Son outlined the rationale behind the downgrade. The revision includes a lower implied price-to-earnings ratio of 7 times, down from 8 times previously, as macroeconomic challenges intensify despite continued strength in corporate profit growth.

A significant warning sign emerged in September when consensus earnings-per-share projections turned negative for the first time in 2023. The month-over-month decline of 0.7% marks a reversal from the positive momentum seen throughout earlier months, with previous upgrades in the memory semiconductor sector now being unwound.

However, UBS maintains an optimistic long-term view on profitability, projecting earnings-per-share expansion of 256% for 2026 and 38% for 2027. Son indicated that the index is likely to trade within a narrow range until third and fourth quarter earnings releases provide additional insight into whether these growth projections remain achievable.

Monetary Tightening and Energy Costs Drive Bond Yields Up

South Korea’s central bank has implemented two rate increases since July. As a result, the yield on 10-year government bonds has surged to 4.5% from 3.4% at the beginning of the year. Meanwhile, crude oil prices hovering above $100 per barrel continue to fuel inflationary pressures.

Currency strength presents an additional challenge for exporters. UBS calculations suggest that each 1% appreciation in the Korean won corresponds to approximately a 1.1% decline in KOSPI earnings.

The investment bank established an optimistic scenario target of 9,200 and a pessimistic scenario target of 5,100 for the KOSPI, a broad range that underscores the high degree of uncertainty surrounding the market’s trajectory.

From a sector perspective, UBS continues to favor memory chip manufacturers. The firm identifies Samsung Electronics and SK Hynix as preferred holdings. Nevertheless, the bank is gradually rotating toward value-oriented and quality names that provide shareholder distributions, acknowledging weakening market momentum and tightening financial conditions.

Regional Markets and Semiconductor Stocks Advance

Meanwhile, Asian equity and fixed-income markets recorded modest gains on Friday as energy prices retreated. Brent crude decreased 0.8% to approximately $104 per barrel, providing some relief from inflation concerns.

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

The yield on 10-year US Treasury securities dropped nine basis points to 4.93% as oil prices eased. Earlier in the week, the yield had reached 5.02% in the aftermath of the Fed’s policy decision.

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

The pullback in energy costs could provide monetary authorities with additional time to evaluate the effects of restrictive policy measures, potentially offering near-term support for both equity and bond markets.
