- Despite a significant cooling in the broader U.S. economy, shelter inflation remains high, preventing the CPI from hitting the Fed’s target.
- The BLS method for calculating housing inflation causes a delay, leading to slower declines in the shelter inflation index compared to rent trends.
- Shelter costs, accounting for 36% of the CPI, significantly influence overall inflation readings.
Housing inflation continues to be a stubborn impediment to the consumer price index (CPI) falling back to the Federal Reserve’s target, as reported on CNBC.
Despite broader economic inflation cooling significantly from pandemic peaks, the shelter inflation index has remained elevated, largely due to how the BLS calculates housing costs.
Understanding The Numbers
Economists note that the CPI shelter index lags behind real-time rent trends. For example, while the annual inflation rate for new rental contracts fell to 0.4% in 1Q24, the shelter index only fell to a 5.2% annual rate in June from a peak of 8% in early 2023.
The BLS methodology involves a “staggered panel” approach, where renters and homeowners are surveyed every six months in rotating groups. This results in a slow-moving index that reflects past conditions rather than current market dynamics.
Consequently, CPI data lags by about 9–12 months, delaying the reflection of real-time drops in rents.
Outsized Influence
Notably, housing costs make up 36% of the CPI, which means shelter inflation is a significant factor in overall inflation readings.
The “owners’ equivalent rent” (OER) category is used to estimate the rental value of owned homes, further complicating the calculation as it doesn’t directly measure home purchase costs.
Broader Implications
As the shelter inflation index lags, it affects the Federal Reserve’s policy decisions. The slow moderation of shelter inflation impacts overall CPI, complicating the Fed’s efforts to control inflation.
Additionally, rents surged during the pandemic due to demand outpacing supply, but with more multifamily units being built, rental growth is slowing, which should eventually be reflected in the CPI.
