WASHINGTON — The Biden administration announced new steps to increase access to affordable housing as still-high prices on groceries and other necessities and high interest rates have dramatically pushed up the cost of living in the post-pandemic years.

Treasury Secretary Janet Yellen promoted the new investments on Monday during a visit to Minneapolis. The investments include providing $100 million through a new fund to support affordable housing financing over the next three years, boosting the Federal Financing Bank’s financing of affordable housing and other measures.

The increased attention to home prices comes as the housing crunch becomes a growing issue in this year’s general election campaign.

“We face a very significant housing supply shortfall that has been building for a long time,” Yellen said in a speech Monday afternoon. “This supply crunch has led to an affordability crunch.”

Yellen said the Democratic administration is “pursuing a broad affordability agenda to address the price pressures that families have been feeling.”

According to the Case-Shiller 20-City Composite Home Price Index, home prices increased by 46% between March 2020 and March 2024. A new Treasury analysis shows that over the past two decades, housing costs have been rising faster than incomes.

Meanwhile, sales of previously occupied U.S. homes fell in May for the third straight month as rising mortgage rates and record-high prices discouraged many prospective homebuyers during what’s traditionally the housing market’s busiest period of the year.
