Progressive Congresswoman Alexandria Ocasio-Cortez (D-NY) told Yahoo Finance in an exclusive interview that corporate "price gouging" has fueled inflation, placing the blame largely on dominant companies that hike prices and rake in profits without fear of competition.

She strongly rejected claims that government stimulus in response to COVID-19 has caused the price spike, warning that such a diagnosis of the problem could lead to spending cuts with dire consequences for millions of people dependent on federal support.

"A lot of these price increases are potentially due to just straight price gouging by corporations," says Ocasio-Cortez, who focused her attention especially on industries with high corporate concentrations.

The remarks from Ocasio-Cortez, who spoke to Yahoo Finance on Jan. 27, came a day after Federal Reserve Chairman Jerome Powell signaled that the central bank will likely raise interest rates at its next policy-setting meeting in mid-March in an effort to rein in inflation.

A Commerce Department report on Friday showed that prices jumped 5.8% last year, the sharpest rise since 1982.

To be sure, Ocasio-Cortez acknowledged other reasons for inflation such as pandemic-related supply chain disruptions and labor shortages.

But her criticism of corporate behavior echoes comments in recent weeks from Sen. Sherrod Brown (D-OH), Sen. Elizabeth Warren (D-MA), and the White House, all of whom have identified exorbitant profits as a contributing factor behind the rise in prices.

Ocasio-Cortez, a critic of corporate power since she joined the House in 2019, called for policy action on antitrust enforcement and worker protections as a means to address inflation.

"If we say there are real antitrust issues here — there's a lot of corporate abuse of power leading to price-gouging," she says. "Then that allows us to pursue lanes such as antitrust and also pursue labor protections, COVID protections, that can help people get back into the workplace and stay safe in the workplace."

Ocasio-Cortez rose to prominence in June 2018 with a surprise upset of incumbent Rep. Joseph Crowley, then the No. 4 Democrat in the House and a potential successor to Speaker Nancy Pelosi. When she took office the following year at the age of 29, she became the youngest woman ever to serve in Congress.

She has amassed nearly 13 million Twitter followers, giving her one of the largest online platforms of a U.S. elected official.

The analysis of inflation from Ocasio-Cortez starkly contrasts with that of Republicans like House Minority Leader Kevin McCarthy (R-CA) and Sen. Ted Cruz (R-TX), who have blamed federal spending for the rise in prices.
