The debt-fueled AI build-out may already be too big to fail

The rapid build-out of artificial intelligence infrastructure has been significantly financed through corporate debt, raising questions about systemic risk if those investments underperform. According to BofA Global strategists, the Federal Reserve's pandemic-era corporate credit facilities—which backstopped investment-grade and high-yield bond markets in 2020—have effectively capped the downside risk for this debt. Even though those facilities are no longer actively deploying capital, their continued presence in the Fed's tool kit signals a de facto backstop for leveraged AI spending.

This matters because it introduces a form of implicit "too big to fail" logic into the credit markets. If AI-related debt comes under severe stress, the precedent exists for emergency central bank intervention, which shapes how investors price risk. However, the facilities have never been used for this purpose, and there is no indication they will be activated.

What to watch is the evolution of credit spreads for tech and AI-related issuers, as well as any Fed commentary referencing its emergency toolkit. The key takeaway is that the perception of a safety net can be as influential as the safety net itself, though deployment would require extraordinary conditions.
