The Bank of Korea has offered an answer to a puzzling question: why isn't a booming stock market making people spend more?
The core issue is a weakened 'wealth effect'. Normally, when assets like stocks rise in value, people feel wealthier and spend more. However, the BOK's analysis suggests this link is currently fractured in Korea for several key reasons.
First, the stock market gains are not evenly distributed. The recent rally, which saw the KOSPI surpass 6,000, was heavily driven by a few semiconductor giants. This means a large portion of the profits went to high-income households, which have a lower tendency to spend additional income compared to lower-income groups. When the rich get richer from stocks, they are more likely to reinvest than to spend.
Second, high volatility is making households cautious. The stock market's rapid climb was marked by sharp ups and downs. This instability makes people view their stock gains as temporary or 'paper profits' rather than a permanent increase in their wealth. As a result, they hesitate to open their wallets based on these uncertain gains.
Third, structural headwinds are at play. Even with a strong market, many Korean households are burdened by high debt levels, which diverts income to loan repayments rather than spending. Furthermore, a rapidly aging population contributes to a more conservative spending pattern overall. These long-term factors create a ceiling on how much consumption can truly recover.
In short, the story of the Korean economy is a tale of two tracks. On one, a powerful AI-driven semiconductor cycle is fueling an incredible stock market boom. On the other, deep-seated issues of inequality, debt, and demographics are keeping consumer spending firmly on the brakes. For spending to truly pick up, the benefits of the market boom need to be distributed more broadly and volatility needs to stabilize.
