President Donald Trump is badgering the Federal Reserve to cut interest rates, but even if the Fed gave in to the pressure, it wouldn’t necessarily lead to lower borrowing costs for consumers.

In fact, economists say, Trump’s ongoing attacks on Fed Chair Jerome Powell and his tariff policies could keep the longer-term interest rates that matter for consumers and businesses higher than they otherwise would be. A less-independent Fed can lead, over time, to higher borrowing costs, as investors worry that inflation may spike in the future. As a result they demand higher yields to own Treasury securities.

Trump has repeatedly urged Powell to cut the short-term interest rate that the central bank controls. The Fed typically reduces its rate during an economic downturn to encourage more borrowing and spending, and raises it to cool the economy and fight inflation when prices rise.

But long-term rates on things like mortgages, auto loans, and credit cards are largely set by market forces. And in recent weeks, fears that Trump’s sweeping tariffs could raise inflation, along with the administration’s threats to the Fed’s independence, have led markets to push those longer term rates higher. It’s not clear that the Fed can fully reverse those trends by itself.

“It’s not automatically true that even if the Fed were to cut rates, that you would see a measured decline in long-term interest rates,” Francesco Bianchi, an economist at Johns Hopkins University, said. “This kind of pressure on the Fed might backfire…if markets don’t believe the Fed has inflation under control.”

Trump renewed calls on Wednesday and Thursday for Powell to reduce the Fed’s short-term rate, telling reporters that the chair is “making a mistake” by not doing so.

And last week, Trump suggested he could fire Powell, while a top aide said that the White House was “studying” whether it could do so.

Stock markets plunged in response, the yield on the 10-year Treasury bond rose, and the dollar fell, an unusual combination that suggested investors were selling most American assets. Markets recovered those losses after Trump said on Tuesday that he had “no intention” of firing the Fed chair.

Still, the threats to the Fed’s independence unnerved Wall Street investors, because they see a Fed free from political pressure as critical to keeping inflation in check. An independent Fed can take unpopular steps, such as raising rates, to fight inflation.

“Threatening the Fed doesn’t soothe markets — it spooks them,” said Lauren Goodwin, chief market strategist at New York Life Investments. “And the result is often the opposite of what any administration wants to see: higher rates, weaker confidence, and more market turmoil.”
