BIS flags 4 risks from debt, AI boom to global stability

The Bank for International Settlements warned Sunday that four simultaneous pressure points — from record public debt to an overheating AI investment boom — risk amplifying one another and threatening global financial stability.

The BIS, the central bank of central banks, identified four pressure points in its annual report published Sunday: resurgent inflation tied to the Middle East conflict, an overheating artificial intelligence investment boom, fragile financial markets and record-high public debt.

"Policy actions must reinforce each other to avoid a pull and push on the global economy," BIS General Manager Pablo Hernandez de Cos said. "Ultimately, success depends on sound fiscal and financial foundations."

The report warned that more frequent supply disruptions could entrench higher inflation expectations among households and businesses. The recent ceasefire between the U.S. and Iran and the reopening of the Strait of Hormuz was "good news" that would avoid extreme scenarios, de Cos said, though oil markets would take time to normalize. On AI, the BIS flagged that supply bottlenecks and intense competition could lead to the kind of overinvestment seen in previous boom-and-bust cycles, with the WSJ reporting that the BIS sees fierce competition driving AI investment spending to levels that could tip some economies into recession.

Record-high public debt, increasingly financed by non-bank intermediaries such as hedge funds, has created what the BIS called "a new sovereign-financial stability nexus" that could trigger sharper drops in sovereign bond values and rapidly tighten financial conditions. "The fact is that today debt is high, and this is financed through non-bank financial intermediaries," de Cos said.

The AI Investment Conundrum

The BIS said the global surge in AI-related capital expenditure has supported growth through expectations of productivity gains, but uncertainty over the durability of that spending is rising. Elevated asset valuations and signs of investor complacency have left core bond markets more fragile, while the financing of the AI boom increasingly relies on debt and complex funding structures across the supply chain.

For central banks, AI poses fundamental questions about how the economy is likely to function, though de Cos said it would be "unwise" to be prescriptive about how they should respond. The BIS called for stronger oversight beyond the banking sector, warning that non-bank players in bond markets and AI investments need adequate regulation to absorb the risks they take.

A Call for Fiscal Discipline

The BIS urged governments to reduce debt levels to preserve central banks' room for maneuver in future economic shocks. Deputy General Manager Andrea Maechler said central banks must be able to "carry out their mandate with complete independence" to defend price stability, adding that "central banks know that they may have to make difficult decisions that would not have political support at the time they need to be made."

The report also highlighted that elevated asset valuations and exuberant risk appetite in financial markets "could unwind abruptly." Each pressure point is manageable individually, Maechler said, but "taken together, they risk amplifying one another and threatening financial stability."

"Policymakers must act now," de Cos said. "Delay will only make the necessary adjustments more costly."
