The global economy has proven surprisingly resilient — but policymakers should not grow complacent. That, in essence, is the message of the Bank for International Settlements in its latest annual report, which warns that several pressures are quietly raising the risk of a sharper financial shock, as CNBC reported.

What the BIS is

Often called the "central bank for central banks," the BIS, based in Basel, Switzerland, is a forum and adviser for the world's monetary authorities. It does not set policy for any country, and it does not predict specific crises. But because it watches risks that cross borders and markets, its flagship Annual Economic Report is closely read by policymakers, and its warnings carry weight.

High debt, financed in new ways

The report's central concern is government debt, which sits at high levels across many large economies. The BIS's general manager, Pablo Hernández de Cos, stressed the urgency of bringing debt down, noting that it is increasingly financed not by traditional long-term holders but through non-bank financial players such as highly leveraged funds. That shift, the BIS argues, can make markets more fragile: if sentiment turns and those investors are forced to sell, government-bond prices can move sharply, tightening financial conditions across the system.

The AI boom as a financial risk

A newer worry is the boom in artificial-intelligence investment. The enormous cost of building data centers and the computing power behind AI is increasingly being funded with debt rather than companies' own cash, the BIS noted. It cautioned that intense competition, supply bottlenecks and rapidly rising capital spending could echo past technology booms — where heavy over-investment ended in sharp market corrections. The institution has also flagged a curious gap: stock-market valuations imply spectacular returns from AI, even as lenders price loans to AI-linked firms as only ordinary risks — a disconnect suggesting someone may be misjudging the danger.

Fragilities that could compound

Beyond debt and AI, the BIS pointed to elevated asset prices, lingering inflation pressures, and trade tensions as additional sources of strain. The concern is less any single threat than the way they could reinforce one another: a shock in one area — an AI-investment pullback, say, or a geopolitical flare-up — could ripple through a system in which leveraged, interconnected investors amplify the moves.

Not a forecast of doom

The BIS was careful not to predict a crash. Its prescription is familiar but pointed: governments should put public finances on a sustainable path, central banks should guard price stability, and regulators should extend their oversight beyond traditional banks to the fast-growing non-bank sector. The broader signal is that the buffers and "circuit-breakers" the financial system has long relied on may be less dependable than they were — and that the time to address the build-up of risk is before, not during, the next shock.
