Key Points
- 01BofA’s Mark Cabana says current interest rates are not restrictive enough
- 02Rates are expected to keep rising, with further yield-curve flattening
- 03Cabana sees a potential move toward a 5%–5.5% policy rate range
- 04AI-driven investment is cited as a factor lifting borrowing costs
BofA outlines a tougher rate backdrop
Bank of America (BAC)’s head of interest rates strategy, Mark Cabana, stated on October 5, 2026 that current interest-rate settings are not restrictive enough. He argued that policy remains too loose to significantly curb economic momentum and that further tightening is likely required.
Cabana said he expects interest rates to continue rising and the yield curve to keep flattening. A flatter curve typically reflects higher short-term rates relative to longer-term yields, signaling that markets are adjusting to a more restrictive policy stance.
Expectation of higher policy rates
Cabana warned that interest rates may need to move toward the 5% to 5.5% range in order to meaningfully tighten financial conditions. In his view, reaching this range would be necessary to slow macroeconomic growth to a more sustainable pace.
The comments indicate that, from Bank of America (BAC)’s perspective, the current policy level has not yet delivered the intended cooling in demand. This outlook points to a prolonged period of elevated borrowing costs compared with recent years of easier money.
AI investment boom and borrowing costs
Alongside the rate outlook, Bank of America (BAC) highlighted the ongoing boom in investment tied to artificial intelligence. This surge in capital spending is identified as one of the factors contributing to higher borrowing costs in financial markets.
The bank’s assessment links AI-related investment to both strong growth in certain sectors and an environment in which financing has become more expensive. As capital continues to flow into AI infrastructure and related projects, funding conditions appear less accommodating than during earlier phases of the cycle.
Implications for financial conditions and markets
Taken together, Cabana’s comments suggest a shift away from an era of easy financial conditions that coincided with the AI spending wave. With rates expected to rise further and the curve to flatten, the backdrop for risk assets that benefited from cheap funding may be changing.
The prospect of policy rates moving toward the mid-single-digit range underscores a more cautious environment for borrowers. Higher funding costs and tighter financial conditions could influence how both investors and companies approach AI-related projects and broader capital allocation in the period ahead.
Key Takeaways
- 01Bank of America signals that policy is likely to stay on a tightening path until rates reach a more clearly restrictive range.
- 02The AI investment boom is now seen as a contributor to rising borrowing costs, not only as a source of growth.
- 03A flatter yield curve and higher expected rates point to a transition away from the easy-money conditions that supported recent market gains.
