BIS warns AI spending surge blurs inflation signals for central banks
A surge in debt-fueled artificial intelligence investment is blurring traditional economic signals, creating a trap for central banks that risk misjudging inflation, the Bank for International Settlements warned.
The Bank for International Settlements says policymakers are navigating an unusually complex environment because artificial intelligence spending is accelerating faster than actual productivity gains. In a new bulletin, the global central bank umbrella body highlighted that this mismatch threatens to distort how inflation and growth are measured.
Much of the current AI expansion is being financed with debt, a detail the BIS highlighted as critical. This capital is flowing directly into physical assets like data centres, advanced chips and digital infrastructure. By injecting immediate demand into the economy long before new capacity comes online, this spending wave is generating short-term inflationary pressures.
Over a longer horizon, the BIS expects the technology to have the opposite effect. If AI successfully boosts efficiency and expands the economy's maximum output, it should act as a disinflationary force. The timing and scale of these productivity benefits remain highly uncertain, however.
This dynamic creates a fundamental challenge for monetary authorities tasked with keeping prices stable. They must determine whether a spike in growth reflects an overheating economy that requires tighter monetary policy, or merely a build-out of future productive capacity that should be accommodated. Because AI simultaneously stimulates demand today and expands supply tomorrow, traditional economic indicators are losing their reliability.
Financial markets are already reflecting an aggressive AI pricing. The BIS noted that soaring technology valuations are creating substantial wealth effects, which could indirectly support consumer spending and broader economic activity. However, the institution explicitly warned that these elevated asset prices increase the risk of financial market bubbles.
The situation is unlikely to unfold uniformly across borders. Different economies will experience varying degrees of AI investment and adoption, leading to diverging inflation and growth patterns that complicate the task for regional central banks. The BIS stopped short of recommending specific policy actions, but stressed that authorities must separate temporary investment surges from permanent productivity shifts to avoid monetary policy misjudgements.
