Republicans test run a new argument: Immigration can cause inflation

Republicans are trying out a new argument this week that spans three top issues of the 2024 campaign: immigration, inflation, and the high cost of housing.

The emerging case is that a Donald Trump-led crackdown on immigration in 2025 may help with the fight against high prices, at least when it comes to finding an affordable home.

It's a case that will likely be received skeptically by many economists, but it's a line of reasoning that was memorialized in the newly unveiled GOP platform ahead of next week's convention in Milwaukee.

As that document puts it, the next president should seal the southern border and deport millions already in the country in part because illegal immigration has "driven up the cost of housing, education, and healthcare for American families."

It's a message at odds with a chorus of economists, as well as Democrats, who have released studies that say Trump's proposals — from tariffs to tax cuts to that immigration crackdown — could cause inflation to spike anew.

But it's an argument gaining steam in GOP circles.

EJ Antoni of the conservative Heritage Foundation has been fielding questions from congressional aides on the topic in recent weeks. His group's case is that there is a 2-to-1 ratio at play: an influx that increases an area's population by 5% translates, he said, into rents going up by 10%.

"It clearly has an impact now," he noted in an interview, citing communities along the southern border as well as major cities where new migrants are traveling as the most impacted.

Jerome Powell's take on the issue

The new message was tested on Capitol Hill this week during a Senate hearing featuring testimony from Federal Reserve Chair Jerome Powell.

Sen. J.D. Vance, a Republican from Ohio and one of the leading contenders to be Donald Trump's vice president, brought up the topic when he had an opportunity to question the Fed chair on Tuesday, saying it was a subject "I imagine most of my colleagues are not asking [about]."

Powell sounded skeptical.

"There's no clear answer, but my sense is that in the long run, immigration is kind of neutral on inflation; in the short run [it] may actually have helped because the labor market got looser," Powell responded.

But he did acknowledge that there could be regional effects, with some communities potentially seeing higher housing costs if faced with a wave of new residents.
