Fed Puts Big Banks' AI Exposure Near $1 Trillion

The Fed dropped the number in its November Financial Stability Report: the biggest US bank holding companies carry close to $1 trillion in exposure to the firms driving the AI buildout. Regulators still call the banking system sound, pointing to high capital ratios. But the mood has shifted fast — 87% of market contacts surveyed by the New York Fed now list AI as a risk, up from 50% in the spring.

The money behind the buildout explains the jitters. Borrowing for advanced computing infrastructure passed $680 billion by October, roughly five times the $130 billion raised across all of 2023. Leases that haven't started yet top $1 trillion, while guarantees and contract commitments clear $2 trillion. None of that lands on the tech giants' balance sheets right away.

Here's how the ties work. Developers lean on cloud giant leases to lock in construction financing, and chipmakers guarantee resale values on GPUs to keep chip purchases flowing. When those same giants take equity stakes, the Fed says it creates a circular financing dynamic. The central bank spelled out the trade-off: the biggest tech firms may absorb losses in a downturn, softening the blow to the wider financial system, but their true economic exposure may run well past what their on-balance-sheet liabilities show.

Banks sit deep inside that web. Their exposure spans tech giants, data center developers, utilities, private credit vehicles and computing-related special purpose entities. The Fed traced the failure chain: weaker-than-expected earnings drag asset prices down, credit tightens, capital spending pulls back, and a slower economy stresses leveraged firms while raising loan losses at banks.

The riskiest slices of these deals sit with high-yield funds, life insurers and private debt vehicles. Investors got a preview in early November, when US stocks shed $2 trillion in a single hour. Survey respondents warned that stretched valuations and debt-heavy funding could amplify losses if a correction sharpens.

Not everyone is rattled. Macro investor Raoul Pal has called Big Tech debt fears overblown, and the Fed noted banks are posting strong profits while their AI-linked exposures go through the annual supervisory stress test. In the Fed's outline, the chain begins with a surprise drop in corporate earnings — which makes tech earnings the next real test for the banks.
