IMF Warns of AI Investment Risks

The International Monetary Fund (IMF) has highlighted a significant risk to global financial markets due to the excessive concentration in artificial intelligence (AI)-related assets, pointing to South Korea’s stock market as particularly exposed.

The fund cautioned that if AI investment returns do not meet expectations, forced selling could accelerate, leading to a sharp rise in market volatility.

In its October 2026 Global Financial Stability Report (GFSR), released on Oct. 13, the IMF urged restrictions on exposure to AI-related derivatives, exchange-traded funds (ETFs), and lending.

South Korea was identified as a major economy with substantial stock market exposure to AI companies.

The KOSPI’s sensitivity to AI stocks, measured by beta, was approximately 0.8 this year, surpassing the corresponding levels in the United States, Japan, and the eurozone.

South Korea’s stock market has already felt the negative effects of its heavy reliance on AI-related shares.

From the start of the second half of the year through Oct. 15, the KOSPI dropped 34.5%, contrasting sharply with gains in U.S. and Taiwanese stocks and an 8% decline in Japan’s Nikkei index.

The KOSPI experienced seven consecutive days of losses from Oct. 6 to Oct. 15, including a 7.57% plunge on Oct. 15, as selling pressure mounted.

The IMF considers the rapid growth of leveraged AI-related investments a critical threat.

AI stocks comprised 28% of holdings in major leveraged ETFs this year, rising from 16% at the end of 2024.

Sonali Jain-Chandra, deputy director of the IMF’s Asia and Pacific Department, stated on Oct. 15 that South Korea is benefiting significantly from AI industry expansion, yet this also increases exposure to industry cycle fluctuations.

A downturn in AI demand could result in weaker exports, reduced investment, and lower government tax revenue, Jain-Chandra explained.

Although the IMF revised its growth forecast for South Korea to 3.3%, it warned against overlooking vulnerabilities tied to such concentration.

Alongside AI equity corrections, the IMF highlighted two other major risks to global financial stability: a sharp rise in government bond yields and cyber threats.

Higher energy costs from the Middle East conflict and large fiscal deficits in major economies are pushing government bond yields upward.

A sudden yield surge could depress valuations across financial markets, including AI-related assets.

Cyberattacks were also flagged as a source of systemic instability as financial services grow increasingly digitalized.

The IMF recommended institutional safeguards, such as sector-specific capital requirements and investment limits.

It advocated measures to curb excessive AI-related borrowing, sustain government debt at manageable levels, and enhance financial institutions’ cyber resilience.
