AI Investment Boom Creates Economic Uncertainty for Central Banks

According to a recent BIS Bulletin (No. 130, July 28, 2026), the artificial intelligence boom is fueling a substantial surge in investment, much of which is being financed through debt accumulation. This expansion is simultaneously strengthening international trade and equity markets across the globe.

The rapid AI-driven investment is generating significant effects on terms of trade and wealth, though these impacts are not distributed equally across different countries and regions.

Despite expectations that artificial intelligence could deliver major productivity gains, the actual economic payoff remains both uncertain and uneven. Productivity improvements are expected to vary considerably depending on the sector and the country in question.

A key challenge for monetary policymakers is that AI's economic effects are working simultaneously on both demand and supply sides of the economy. This dual impact obscures traditional cyclical signals, making it more difficult for central banks to accurately assess the true underlying economic conditions and to calibrate appropriate monetary policy responses.
