KOSPI Rise Creates US$1 Trillion Wealth Effect

Overview

This JPMorgan macro research report analyzes the impact of South Korea's stock market (KOSPI) sharp rally in 2026 on household wealth and domestic consumption. The report states that KOSPI has risen 109% YTD 2026, creating W1 trillion (W1,000T) in household wealth, 4.5 times the 2020 peak. Based on historical consumption conversion rate of 1.3%, it is expected to generate W14T in incremental consumption; in optimistic scenarios (using Western 4% conversion rate), consumption increment could reach W43T (equivalent to 1.6% of 2025 GDP). The report details which industries and companies will benefit most from this wealth effect.

Core views

The report's core argument holds that the wealth effect created by the current KOSPI rally will be stronger than in historical cycles, based on three key factors: 1) Unprecedented speed and magnitude of stock market gains with YTD rise of 109%; 2) Rapidly increasing household participation in equity markets – stocks + funds accounted for 23% of household financial assets in 2025; 3) Government policies restricting diversion of stock gains into real estate, channeling more wealth toward consumption. The wealth effect is expected to concentrate primarily in high-end discretionary goods sectors such as luxury goods and tourism, with limited impact on necessities/FMCG. Specifically, department stores (Shinsegae, Hyundai Dept. Store, etc.) stand to benefit most from high-end consumption growth; tourism & hotels sector (Hana Tour, Korean Air, etc.) will also benefit, though partially offset by high oil prices and weak won; real estate-related sectors (furniture, appliances) exhibit lower/ more lagged benefits. The report particularly notes the wealth effect typically lags stock market gains by several months, with consumption boost likely materializing in the second half of 2026. Furthermore, higher-income households will show consumption growth first due to higher stock ownership, potentially extending to broader income groups later.

Analysis framework

The report employs a top-down analytical approach, first quantifying household wealth expansion from stock market gains, then estimating consumption impact via historical conversion rates. Specific steps: 1) Calculate household wealth growth from KOSPI appreciation: Based on Korea Securities Depository data, considering retail investors' stock holdings ratio (35% in 2025) and conversion efficiency from market cap growth to household wealth (81% in 2025), estimated YTD 2026 household stock wealth increased by W1,065T. 2) Estimate wealth effect: Applied Bank of Korea's historical avg. conversion rate (1.3%) yielding W14T consumption increment; also referenced higher Western conversion rates (4%) as optimistic scenario, yielding W43T increment. 3) Analyze sector differentials: Determined varying sectoral benefits based on wealth sensitivity (high-end discretionary > necessities) and historical correlation.

• Department Stores (Shinsegae, Hyundai Dept. Store, etc.)

  Primary channel for high-end consumer goods, most direct beneficiary of wealth effect

  Strengths

  Dominant position in high-end retail sector, potential for both average ticket size and traffic improvement

  Comparison

  Outperformance among consumer stocks, YTD gains exceeding KOSPI

• Travel & Hotels (Hana Tour, Korean Air, etc.)

  Wealth effect typically drives international travel demand

  Weaknesses

  Partially offset by high oil prices and weak won

  Comparison

  Relatively weaker performance, reduced preference for travel agencies among high-end consumers

  Risks

  Potential shift to domestic luxury hotels if international travel restricted

Impact & implications

The report concludes KOSPI-driven wealth effect will significantly boost domestic consumption in South Korea, particularly in high-end discretionary goods. This will benefit department stores, tourism, luxury hotels sectors, while minimizing impact on essentials/FMCG. The wealth effect is expected to manifest in H2 2026, providing sustained growth momentum to relevant industries. Additionally, the report notes uneven distribution of this wealth effect – higher-income households and younger investors, due to higher stock ownership and stronger consumption propensity, will be primary consumption growth drivers. Government policies restricting real estate capital flows will further amplify the consumption boost from wealth effect.

Risks

• Wealth effect typically lags stock market performance, potentially delaying manifestation
• Concentrated stock ownership among high-income households may limit widespread consumption growth
• Retail investors' stock selection capability may constrain actual wealth growth
• Insufficient profit-taking may weaken wealth effect

What to watch

• Changes in household stock allocation ratio
• High-end consumption data trends
• Government real estate policy adjustments
• International oil price and exchange rate movements
