BofA Warns 'AI Put' Now Drives Stock Market More Than Bond Yields
Bank of America strategists argue the real risk to equities isn't rising bond yields but the fragile confidence propping up AI-driven stocks.
Bank of America Global Research strategists are sounding an alarm that cuts against the prevailing Wall Street narrative: while most investors are fixating on surging global bond yields as the primary threat to U.S. equities, BofA says the market's true vulnerability is something else entirely — what analysts are calling the "AI Put."
The term borrows from the long-standing concept of the "Fed Put," the widely held belief that the Federal Reserve will intervene to support markets during sharp downturns.

The concern is that this AI-anchored optimism has quietly displaced traditional market fundamentals as the dominant force in stock pricing. If that confidence were to crack — whether through disappointing earnings from major AI players, a regulatory shock, or simply a loss of momentum in the AI investment cycle — the resulting selloff could prove far more damaging than anything a bond yield spike might trigger on its own.
Rising global bond yields have rattled markets before, and they remain a legitimate watchpoint for portfolio managers worldwide. But BofA's framing suggests that yield anxiety may be serving as a distraction from a deeper, structural complacency baked into current equity valuations. When the most important support for a market is sentiment-driven rather than earnings-driven, the floor can disappear faster than models predict.
The warning arrives at a moment when AI-related stocks continue to command premium multiples across major indexes, making the broader market increasingly dependent on the durability of that single thematic bet. Continue reading at MarketWatch.com
