Fed chair Kevin Warsh calls AI the most consequential economic change of his lifetime

Warsh on AI and the economy

Federal Reserve Chair Kevin Warsh said on Friday, 16 October 2026, that the rise of artificial intelligence is probably the most decisive change for the US and global economy of his lifetime. He made the remark on the sidelines of the annual meetings of the International Monetary Fund and World Bank in Bangkok, where he held a conversation with IMF Managing Director Kristalina Georgieva. Warsh has been a Fed governor for 20 years, and Donald Trump installed him as chair, according to BFMTV. He described AI as the main driver of recent growth in the global economy and trade, a force that has also pushed up stock prices on Wall Street and in Asia. Warsh said the technology will transform the real economy, and that countries and companies able to use it will become more productive and create more wealth.

Short-term price pressure, longer-term gains

As a central banker, Warsh said he is watching the macroeconomic effects of the boom closely. In the short run, the surge in AI investment could push prices higher through overheated demand and spending. Over time, he argued, the world economy will gain a considerable benefit. He said the effect on employment over the next 12 to 18 months is unknown, although economies that use the technology well will gain. Notícias ao Minuto reported that he expects AI to first boost demand before productivity gains arrive through greater supply, and that he sees it as a positive supply shock over the medium term, unlike the shocks caused by wars or geopolitical conflicts. He also said central banks will eventually be able to draw on far more real-time data, which could help separate genuine economic signals from temporary fluctuations or measurement errors.

IMF warnings about a sudden reversal

The IMF warned this week that the AI boom poses risks to the economy and financial stability, particularly if markets and investment turn around abruptly. Concerns focus on the profits and productivity gains of the sector. Notícias ao Minuto reported that the Fund raised its 2026 global growth forecast to 3.1%, driven mainly by massive AI investment. Warsh acknowledged these dangers during his conversation with Georgieva on Friday. He said the road will probably be full of obstacles, citing uncertainty about the technology itself and about the market structure that will eventually take hold. He also asked who will profit, and what happens to those who bet on gains that collide with reality.

Rates and what comes next

The Fed raised its policy rate by 0.25 percentage points in mid-September, setting a range of 3.75% to 4% to bring inflation down. At the Bangkok event, Warsh gave no indication of what comes next for interest rates, and he did not prejudge the Fed's decisions ahead of its meeting on 27 and 28 October. Recent US inflation data have added uncertainty about the direction of monetary policy. The timeline below places the September rate move, Friday's remarks and the next scheduled meeting.
