WASHINGTON, Oct 15, (AP): With characteristic bravado, Donald Trump has vowed that if voters return him to the White House, "inflation will vanish completely." It’s a message tailored for Americans who are still exasperated by the jump in consumer prices that began 3 1/2 years ago. Yet most mainstream economists say Trump’s policy proposals wouldn't vanquish inflation.

They’d make it worse. They warn that his plans to impose huge tariffs on imported goods, deport millions of migrant workers and demand a voice in the Federal Reserve's interest rate policies would likely send prices surging. Sixteen Nobel Prize-winning economists signed a letter in June expressing fear that Trump's proposals would "reignite’’ inflation, which has plummeted since peaking at 9.1% in 2022 and is nearly back to the Fed’s 2% target.

Last month, the Peterson Institute for International Economics predicted that Trump’s policies would drive consumer prices sharply higher two years into his second term. Peterson's analysis concluded that inflation, which would otherwise register 1.9% in 2026, would instead jump to between 6% and 9.3% if Trump's economic proposals were adopted.

Many economists aren’t thrilled with Vice President Kamala Harris’ economic agenda, either. They dismiss, for example, her proposal to combat price gouging as an ineffective tool against high grocery prices. But they don’t regard her policies as particularly inflationary. Moody’s Analytics has estimated that Harris' policies would leave the inflation outlook virtually unchanged, even if she enjoyed a Democratic majority in both chambers of Congress.

An unfettered Trump, by contrast, would leave prices higher by 1.1 percentage points in 2025 and 0.8 percentage points in 2026. Taxes on imports - tariffs - are Trump’s go-to economic policy. He argues that tariffs protect American factory jobs from foreign competition and deliver a host of other benefits.
