Behind the AI Funding Frenzy: South Korea's Central Bank Flags Growing Financial Fragility

A new report from the Bank of Korea's investigation bureau casts a spotlight on the intricate financing web underpinning the nation's artificial intelligence boom. The analysis reveals how rapid capital mobilization could be sowing the seeds for future financial instability, urging closer scrutiny of the sector's evolving risk profile.

The Intricate Funding Web: Bonds, Collateral, and Hidden Leverage

The report highlights a surge in external financing by hyperscale data center operators this year. Primary tools include long-term corporate bonds and specialized credit lines secured by high-performance Graphics Processing Units (GPUs), often linked to "AI-dedicated cloud" services. Convertible bonds are also widely used.

More concerning is the active use of off-balance-sheet financing through Special Purpose Vehicles (SPVs), joint ventures, and equipment leasing. These practices obscure the true scale of debt, making underlying risks harder to identify and assess.

Core Risks: Overestimated Returns and Opaque Linkages

This financing structure fosters a critical vulnerability: the expected returns from AI investments may be systematically overstated. When massive funding is based on overly optimistic revenue projections, any shortfall in actual performance could trigger widespread distress.

The report points to "circular transactions" within the supply chain, where major AI chipmakers and tech giants provide financial support and investments to lock in future revenue with partners. While intended to secure business, the growing scale of these interconnected arrangements creates a dense network of credit. A shock at any point could propagate rapidly through both supply and financial channels.

Pressure Points and Amplified Contagion

Although leading firms currently maintain strong balance sheets, the report cautions that fragility is accumulating in a environment of rising long-term interest rates. Two key risk factors stand out:

  • Delayed AI Monetization: If AI applications fail to generate sufficient cash flow to service debts within expected timelines, solvency will come under pressure.
  • Diffusion of Circular Financial Shocks: The credit relationships within the supply chain could act as conduits for spreading financial stress.

Particular attention is needed on AI-dedicated cloud providers with weaker financials and lower operational transparency, identified as potential weak links.

South Korea's Dilemma: Prime Beneficiary or Shock Absorber?

The report concludes with a stark reminder: South Korea is a top beneficiary of the global AI boom, with its tech sector deeply embedded in international supply chains. This deep integration is a double-edged sword. It fuels growth but also means the country could be more exposed and susceptible to amplified transmission of both real economic shocks and financial turbulence from abroad.

Continuous monitoring of these emerging vulnerabilities is essential to prevent localized risks from escalating into broader systemic stress.
