- IMF officials state that the current valuation of AI-related stocks may not necessarily indicate a bubble, and regulators should focus more on changes in the financing structures of large tech companies.
- In their view, the real risk does not lie in short-term stock price fluctuations, but in companies using long-term debt to invest in rapidly updating AI infrastructure, creating a maturity mismatch.
- If future AI commercialization returns fall short of expectations, this "borrowing long to buy short" expansion model could quickly translate into cash flow and debt repayment pressures, impacting financial stability.
Valuations Do Not Show Typical Bubble Characteristics
Adrian, Director of the IMF's Monetary and Capital Markets Department, pointed out that judging a bubble cannot rely solely on rising stock prices, but on whether valuations are significantly detached from earnings. Although the AI sector has surged recently, corporate earnings have consistently exceeded expectations, and the gains are more concentrated in chips and underlying hardware, without indiscriminate speculation.
Financing Maturity Poses a Greater Risk
Compared to stock valuations, he is more concerned about cloud service providers and large tech companies continuously increasing leverage by financing through long-term or even over ten-year bonds to purchase GPUs and build data centers. Due to the rapid update of related equipment, the economic lifespan of assets may be significantly shorter than the debt maturity.
Falling Returns Will Amplify Cash Flow Pressure
As long as cutting-edge models continue to generate revenue and customers are willing to pay, this model can be maintained. However, if the pace of AI commercialization slows or investment returns fall short of expectations, the ability of companies to cover debt costs with cash flow will weaken, and market vulnerabilities will quickly become apparent.
Regulatory Discussion Shifts from Bubble to Structure
This statement responds to the recent global discussion surrounding the "AI bubble." The BIS has already listed AI as one of the financial stability risks, and European Central Bank officials have also expressed related concerns. For regulators, the next phase of focus may not only be on valuation levels but also on the matching degree between financing maturity, asset lifespan, and leverage expansion.
