How the Consumer Price Index Relates to the Housing Market

When it comes to understanding what’s happening with mortgage rates, rents, and home prices, the Consumer Price Index (CPI) often gets attention in financial headlines because of its close connection to housing costs and inflation. It’s a key measure of inflation that reflects changes in the cost of living, including housing, and it indirectly influences mortgage rates through its impact on Federal Reserve policy.

At CapCenter, we want to break it down for you. Let’s look at how CPI works, how it connects to housing costs, and what today’s newly released June CPI numbers could mean for your next move.

Understanding CPI and Housing: A Comprehensive Look

The Consumer Price Index (CPI), published monthly by the Bureau of Labor Statistics (BLS), is one of the most widely watched indicators of inflation. It measures how prices change over time for a “basket” of goods and services—like groceries, gas, medical care, and shelter—giving a snapshot of the overall cost of living.

The main purpose of CPI is to track inflation and assess how far a household’s dollar goes in covering everyday expenses. Policymakers, including the Federal Reserve, use it as one of several key indicators to guide economic decisions.

Shelter Costs in the CPI

Housing plays an outsized role in CPI, accounting for about one-third of the index—the largest single component. This "shelter" category includes:

• Rent for tenants, based on surveys of about 40,000 rental units collected every six months.
• Owners’ Equivalent Rent (OER) for homeowners, an imputed value estimating what it would cost for a homeowner to rent their own home in today’s market.
• Utilities and other housing-related expenses, which are measured separately.

Unlike home purchase prices, which reflect investment value and can fluctuate due to interest rates and buyer demand, OER aims to capture the ongoing cost of living in a home. This is because CPI measures consumption, not investments. OER accounts for the housing services homeowners consume, regardless of mortgage status or home equity.

Because rental agreements typically adjust annually and data is sampled semiannually, there’s often a lag in CPI shelter data. Even as market rents begin to cool, CPI’s shelter component may remain elevated for months.

This method makes CPI a comprehensive measure of housing costs, but it’s important to note it doesn’t directly track home prices or mortgage payments.

How CPI Connects to Housing Costs

CPI doesn’t shape the housing market directly. Instead, it reflects changes in housing costs and contributes to how economic policy responds. Here’s how it connects:

1. CPI measures inflation, including rising shelter costs.
2. The Federal Reserve considers CPI—alongside other indicators—to determine whether to adjust interest rates.
3. Fed rate decisions influence borrowing costs, including mortgage rates.
4. Mortgage rates affect housing demand, affordability, and indirectly, home prices.

In short: CPI doesn’t directly drive home prices, but its shelter data influences Fed policy, which indirectly impacts the housing market.

June CPI: Key Numbers and Implications

The BLS released June’s CPI report this week. Here’s what it showed:

• Headline CPI rose 0.3% in June, bringing annual inflation to 2.7% (up from 2.4% in May).
• Core CPI (excluding food and energy) climbed 0.2% monthly, now 2.9% year-over-year.
• Shelter costs rose 0.2% for the month and 3.8% year-over-year, their smallest annual gain since early 2021.
• Early signs of tariff-driven price increases appeared in goods categories like furniture and apparel.

What This Means for Homebuyers and Homeowners

Recent reports suggest rent growth in many areas has slowed significantly. However, CPI shelter costs rose 0.2% in June, showing only a slight cooling so far. Because of CPI’s lagging shelter data, this slowdown in market rents may take several more months to fully appear in inflation reports.

The Fed Is Watching Closely While June’s numbers show progress, inflation is still above the Fed’s 2% target. Economists expect the Fed to hold rates steady and possibly delay any cuts until fall 2025.

Mortgage Rates Likely to Stay Elevated (for Now) Until CPI shows sustained cooling—especially in shelter—mortgage rates are unlikely to drop significantly.
