The issue of housing inflation in the United States has been a lingering concern for economists, especially as it has not decreased as quickly as other forms of inflation in the economy. The fact that housing accounts for a significant portion of the Consumer Price Index (CPI), at 36%, makes it a critical factor in understanding overall inflation trends. This high percentage demonstrates the outsized influence that movements in shelter prices can have on inflation readings. As such, the slow decline in housing inflation has become a major obstacle in the CPI’s ability to normalize, according to experts in the field.
Shelter inflation, which is essentially a measure of U.S. rental prices, has been a point of contention due to its slow decrease despite improvements in the rental market. The discrepancy between the shelter inflation index and real-time rental market trends has puzzled economists. While the annual inflation rate for new rental contracts has dropped significantly, the shelter inflation index has not kept pace, indicating a lag in reflecting current market dynamics. This lag is primarily attributed to the way in which the Bureau of Labor Statistics calculates shelter prices, resulting in delayed changes in the CPI readings.
One of the key challenges in assessing housing inflation is the treatment of homeowners in the CPI calculations. Unlike renters, homeowners incur a wide range of costs that are not considered standard consumption goods. Items such as mortgage payments, property taxes, and maintenance expenses are seen as capital costs rather than regular consumption expenditures. This distinction poses a challenge in accurately measuring the average cost of housing in the economy. To address this issue, the BLS uses the concept of “owners’ equivalent rent” to equate homeowners with renters in the CPI calculations.
The slow movement of the shelter inflation index is largely due to the staggered sampling approach used by the government in collecting rental data. By surveying a panel of renters and homeowners on a semi-annual basis, the BLS constructs the shelter index, resulting in a lag between current market conditions and CPI readings. As a result, changes in shelter inflation can take several years to fully reflect recent trends in the rental market. This delay has been acknowledged by policymakers, including Federal Reserve Chair Jerome Powell, who highlighted the importance of considering the shelter delay in inflation decisions.
Despite the current challenges in housing inflation, experts believe that shelter inflation will eventually catch up to the trend in new rental contracts. As more rental units become available and demand stabilizes, rental prices are expected to moderate further. The increase in the construction of multifamily units has already contributed to a slowdown in rent growth, indicating positive developments in the rental market. Moving forward, the expectation is for continued deceleration in the rent component, leading to a more balanced housing market overall.
While housing inflation has remained stubbornly high in the U.S. economy, there are signs of progress and moderation on the horizon. By understanding the complexities of shelter inflation and the challenges in measuring housing costs for homeowners, policymakers and economists can take steps to address the lag in CPI readings and ensure a more accurate reflection of inflation trends in the future.
