The home price rebound could complicate the Fed's efforts to tame inflation

The Federal Reserve may have a new problem: The housing market’s recent reversal could keep inflation from coming down as much as the central bank wants.

The latest data shows that more homebuyers are coming into the market, while for-sale inventory continues to shrink. As a result, home prices — which affect a major factor in the government’s inflation measure — have unexpectedly ticked higher month over month since the beginning of the year.

This development could prompt a change in the Fed's course of action, even after it said this week that it plans to take a more wait-and-see approach to future interest rate hikes.

"The hope has been for a while that the rent component and the shelter component of housing, which makes up roughly 40% of the [core] CPI basket, would begin to come down because housing has been slowing down," Torsten Slok, chief economist at Apollo Global Management, told Yahoo Finance. "But the problem is housing is actually beginning to show signs of moving higher."

Housing prices and inflation

Housing costs contribute about a third of the basket for the Consumer Price Index (CPI), the main gauge for inflation, and 40% of the basket for core CPI, which strips out the volatile food and energy components

The housing component is made up of four categories, but rent and owners' equivalent rent (OER), or the rent homeowners would pay for similar homes, are the two largest. The shelter component also includes lodging away from home and tenants’ and household insurance.

"The weights in the basket are a reflection of your spending patterns. And therefore, housing has gone up so much that the weight of housing has increased in the last few years because people are now spending even more money on housing rather than on restaurants, travel, and hotels," Torsten explained.

For instance, the shelter category in CPI climbed to 8.2% year over year in March 2023, the biggest 12-month gain since June 1982 and much higher than the range it's been at in the last decade. March's rate is also four times higher than the Fed's target rate of 2% per year for overall inflation.

While home price growth is not directly used in CPI calculations, past trends have shown it strongly correlates with housing inflation, according to the Federal Reserve Bank of Dallas.

"If the housing market rebounds and if people are out there buying homes, that means that rents are also going up again because there's more demand for housing," Torsten said.

Inflation is 'just not coming down'

Home prices do appear to be reversing.
