Filling up the car has clearly become a costly reminder that inflation doesn’t just show up on grocery receipts. When oil prices surge like they have over the past several months, drivers feel it at the pump. But the damage might not stop when they pull away.
A more costly tank of gas can also complicate the Federal Reserve’s next decision, potentially keeping borrowing costs high for families trying to buy a house, finance a car or pay down debt.
That’s the warning in a new Bank of America report shared with me.
Bank of America rates strategist Ralph Axel views a risk that goes far beyond another expensive fill-up. His latest research underscores that oil prices might have an outsized influence on the Federal Reserve’s next move, just as Americans hope borrowing costs will ease.

Bank of America warns oil could push interest rates much higher
Bank of America sees a strong connection, with something typical consumers rarely think about together which is crude oil and the cost of borrowing money calling them ‘close cousins’.

In a November 5 research note, rates strategist Ralph Axel warned oil prices could have more influence over borrowing costs than investors realize, especially if fighting involving Iran and Ukraine keeps energy supplies under pressure.
“Our main takeaway is that if oil prices continue to rise over the next 3-6 months, we could see significantly higher interest rates,” Axel wrote.
Moreover, he has receipts to back up those claims: during 2026 through November 4, U.S. two-year swap rates rose a cumulative 196 basis points on days oil gained ground, but fell 83 basis points on other days. That left rates up 113 basis points overall.
Oil helps power transportation, manufacturing and daily commutes and when prices rise and stay elevated, consumers have to pay more, while investors might demand greater compensation for the likely inflationary pressures.
That pushes market interest rates higher and can complicate the Fed’s fight against rising prices.
Also, the Fed has already shown it’s concerned, having raised its benchmark rate by a quarter percentage point in September, then held it at 3.75% to 4% in October. Two policymakers wanted another increase.
“I expect that monetary policy will need to move to a restrictive stance,” Cleveland Fed President Beth Hammack said on November 5, citing persistent inflation.
BofA believes resilient consumer spending and lingering inflation could leave the Fed with room to tighten further.
Rising oil prices could squeeze Americans in more ways than one
Consumers are already hurting, and in watching their budgets, another oil-price spike could cause problems well beyond the gas pump.
For perspective, consumer prices rose 3.7% in September from a year earlier, while the Federal Reserve’s preferred inflation gauge climbed 3.6%.
Energy prices, meanwhile, were up 20.4%. With inflation already above the Fed’s 2% target, another sustained increase in fuel costs could make the central bank’s job harder.
It’s important to understand that gasoline isn’t the only expense tied to oil. Diesel powers trucks delivering groceries and other goods, while petroleum feeds into manufacturing and shipping costs. Businesses could absorb some increases, but others will eventually be passed on to shoppers. If interest rates also rise, financing a car or carrying debt will become a lot more expensive.
Bank of America sees another complication.
Its research underscores the enormous U.S. capital-spending boom, including AI infrastructure, helping keep inflation-adjusted interest rates unusually strong in 2026.
Also, homebuyers have plenty at stake. Freddie Mac’s average 30-year fixed mortgage rate recently stood at 7.18%. Mortgage rates don’t move in tandem with oil or Fed policy, but higher market yields might make already difficult monthly payments even harder to manage.
What could trigger the Fed’s next interest-rate move?
Oil’s sharp pullback this week offers some respite. Brent crude was heading for a roughly 16% weekly decline on Friday as hopes of easing tensions in the Middle East grew, suggesting that another inflationary surge isn’t inevitable.
Still, Bank of America cautions that peace might not necessarily restore disrupted supplies overnight.
Even if the Iran conflict subsides, the bank warns, “we cannot be assured that crude supply from the Gulf would reliably resume to its prewar rate.”
Damaged Russian refineries and depleted global oil inventories only add to the uncertainty.
That leaves the Fed facing two different possibilities. If crude stabilizes and inflation moderates, policymakers could leave rates unchanged, particularly if employment weakens. But another sustained oil rally could strengthen expectations for additional tightening.
Investors and the general consumer need to look at October’s employment report, which arrives on November 6, followed by consumer inflation data on November 10 and the Fed’s preferred PCE inflation report on November 25. Also, the central bank meets again December 8–9.
