"The central bank of central banks" sounds the alarm on the AI bubble: A trillion-dollar capital expenditure frenzy risks triggering a prolonged crash.

The Bank for International Settlements (BIS) has warned that the AI investment boom—led by technology giants—could evolve into a "prolonged investment bust," destabilizing global financial markets and harming the world economy. Known as "the central bank of central banks," the BIS has directly flagged the current AI market’s excessive exuberance, issuing a clear risk warning from one of the world’s most authoritative financial institutions. In its annual economic report released on Sunday, the BIS noted that the world’s five largest "hyperscale" cloud-computing firms are projected to spend over $1 trillion in capital expenditures collectively between 2025 and the end of 2026. Should the technology sector’s actual returns fall short of expectations, investors could swiftly tighten financing, causing this capital-spending boom to abruptly reverse—and descend into a "protracted investment slump"—with cascading effects on global financial conditions. According to the Financial Times, signs of market instability have already emerged. Following SpaceX’s $86 billion IPO this month, the company immediately launched a $25 billion bond issuance. Allianz Group’s Chief Investment Officer warned this week that such a move signals the market has entered a "bubble zone." Since SpaceX’s listing, equity markets have remained volatile, compounded by rising market expectations of further Federal Reserve interest-rate hikes—leading investors to adopt markedly more cautious sentiment. The BIS also cautioned that the energy shock triggered by the U.S.-Iran conflict and the near-closure of the Strait of Hormuz trade route has yet to fully dissipate; its inflationary impact "has already begun to materialize and may persist for an extended period," compounding with AI-bubble risks to form multiple threats confronting the global economy. Behind the trillion-dollar capital spending: uncertain returns The core contradiction fueling today’s AI boom lies in the gap between massive capital inflows and still-uncertain commercial returns. Technology firms have aggressively entered global credit markets, raising hundreds of billions of dollars to fund AI projects—and leveraging corporate credit spreads near their lowest levels this century to secure low-cost financing. Meanwhile, U.S. equity markets’ record highs continue to attract corporate equity financing. SpaceX’s $86 billion IPO epitomizes surging demand for AI-related assets. Major investors have issued warnings: should AI investments fail to deliver expected returns, this wave of debt issuance will severely test the market’s risk tolerance. The BIS explicitly stated in its report: "Disappointing returns could trigger a sudden contraction in financing, transforming the capital-expenditure boom into a persistent investment slump—and potentially triggering cascading effects on financial conditions."

From hedge to hazard: The IMF has, for the first time, classified the AI boom alongside oil shocks and debt burdens as part of a "risk portfolio."

The International Monetary Fund (IMF) is redefining its characterization of the AI boom. On the eve of hosting next week’s global economic summit, the IMF has placed "imbalanced AI growth" on equal footing with protracted energy shocks and record-high debt accumulation—labeling the three together as a "risk portfolio" confronting the global economy, and urging governments worldwide to take urgent action. This latest statement by IMF Managing Director Kristalina Georgieva marks a significant shift: for the first time, the AI capital-expenditure surge has been elevated to the same level of concern as oil crises and sovereign debt crises. Previously, the IMF had viewed investments in artificial intelligence and data centers as partially offsetting energy shortages caused by the Middle East conflict; now, however, this "hedging force" has been recast as one of the sources of risk. At the heart of the IMF’s warning lies the amplifying effect of these three risks converging: energy shocks push up inflation and interest rates; higher rates, in turn, exacerbate debt burdens already nearing critical thresholds. With global public debt projected to surpass 100% of GDP by 2029—two years earlier than previously anticipated—the interplay among these factors grows increasingly precarious. AI: From hedge to hazard In this latest statement, AI’s role has undergone a pivotal shift. The IMF had previously observed that investments in AI and data centers partially offset energy-shortage impacts; now, Georgieva’s language refers to an "imbalanced AI boom," placing it alongside energy shocks and debt accumulation within the global "risk portfolio." This signifies that the AI capital-expenditure surge has, for the first time, shifted—from being discussed primarily as a "growth engine"—into the realm of "risk sources."
