Data Analysis

The Bureau of Labor Statistics reported the Consumer Price Index rose 0.4 percent in August 2026 and 3.4 percent over the year, with the shelter index up 3.0 percent over the same twelve months.

Core inflation slowed to 2.4 percent from 2.5 percent. Gasoline rose 3.9 percent in the month and accounted for over a third of the monthly increase.

The Consumer Price Index rose 0.4 percent in August 2026 on a seasonally adjusted basis after rising 0.1 percent in July, and 3.4 percent over the last twelve months before seasonal adjustment, the Bureau of Labor Statistics reported September 11. The shelter index rose 0.3 percent in the month and 3.0 percent over the year. Core inflation, which excludes food and energy, rose 0.3 percent in the month and 2.4 percent over the year, down from 2.5 percent for the twelve months ending July. Energy rose 16.3 percent over the year.

What did the August CPI report show?

Two things moving in opposite directions. The headline number got worse and the underlying number got slightly better.

All items rose 0.4 percent in August after a 0.1 percent rise in July, which is a four-fold acceleration in the monthly pace. Over twelve months the all items index stood at 3.4 percent. Meanwhile the all items less food and energy index rose 2.4 percent over the year, following a 2.5 percent increase over the twelve months ending July.

The distance between those two figures is the story. Energy rose 16.3 percent over the year. Food rose 2.7 percent. Both sit above the 2.4 percent core reading, and energy sits far above it.

How much of the increase was gasoline?

Most of it. BLS states that the index for gasoline rose 3.9 percent in August, "accounting for over one third of the monthly all items increase." The energy index as a whole rose 2.1 percent over the month. Food rose 0.1 percent.

This is the same impulse that showed up one stage earlier in Thursday's producer price report. The August Producer Price Index put final demand up 0.4 percent in the month and 5.4 percent over the year, with BLS attributing over three-fourths of the broad-based rise to final demand energy, which moved up 4.2 percent, and tracing over a third of the goods increase to diesel fuel, which jumped 24.1 percent. Producer-side core ran at 4.7 percent over the year against consumer-side core at 2.4 percent.

For a housing reader the useful part is what this is not. An energy-driven print is not the same signal as a broad price acceleration, and the components that bear on housing costs did not move the way the headline did.

What does shelter inflation at 3 percent mean for housing?

Shelter is the largest single component of the Consumer Price Index, so its behavior matters more to the overall number than any other line in the report.

In August the shelter index rose 0.3 percent after rising 0.1 percent in July, and 3.0 percent over the year. Underneath it, the index for owners' equivalent rent rose 0.2 percent in August, as did the index for rent.

The monthly shelter figure accelerated from July. The annual figure of 3.0 percent sits above core and below headline. Anyone reading this as evidence of a turn in housing costs should note that shelter in CPI is a slow-moving series by construction, which is the subject of the next section.

How do Florida rents compare with national shelter inflation?

They are running softer, and the two measurements are not the same thing.

Zillow's observed rent index for August 2026 put the national figure at $1,948, up 2.5 percent over the year. In Florida, Miami was $2,666 and up 1.6 percent, Jacksonville $1,696 and up 1.8 percent, Orlando $1,942 and up 0.7 percent, and Tampa $2,001 and down 0.1 percent. Every one of those four sits below the national Zillow figure, and all four sit below the 3.0 percent shelter reading in this CPI report.

The gap is partly real and partly definitional, and the definitional half matters. Zillow's index tracks asking rents on new leases. CPI shelter covers the entire stock of housing, including leases signed a year or two ago that are still rolling toward current market rents, and it includes owners' equivalent rent, which estimates what owner-occupied homes would rent for and is not a transaction price at all. A new-lease index turns first. A whole-stock index turns later.

So Florida rents easing ahead of the national shelter index is what the construction of the two series would predict. It is not evidence that CPI is wrong, and it is not a forecast that CPI shelter follows Florida down.

What does this mean ahead of the Fed meeting?

The Federal Open Market Committee meets September 15 and 16, with a press conference scheduled for 2:30 p.m. Eastern on September 16. This is the last major inflation reading before that meeting.

Mortgage rates are the transmission line that Florida buyers actually feel. Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed rate at 6.76 percent for the week ending September 10, up from 6.71 percent the prior week and 6.35 percent a year earlier. The 15-year fixed rate was 6.09 percent.

Those rates are set in the bond market, which prices the whole path of inflation and policy rather than any single month. This desk does not forecast rate moves and nothing in this report determines one.

What Florida buyers can work with is the other side of the transaction. Florida Realtors reported a statewide median single-family price of $425,000 in July 2026 on 4.5 months of supply. Financing costs have not improved this year. Inventory has.

Limitations

The Consumer Price Index is a national measure. This report carries no Florida figure and no Florida metropolitan area figure. BLS publishes a separate South region CPI release on its own schedule later in the month, and the most recent one covers July 2026 and names no Florida metropolitan area.

The monthly changes cited here are seasonally adjusted and the twelve-month changes are not, which is how BLS presents them. The two are not interchangeable.

Shelter in the CPI is not a measure of home prices. It measures rent and owners' equivalent rent, an estimate of what an owner-occupied home would rent for. A reader looking for Florida home price movement should use the Florida Realtors closed median or one of the metro price series, not this index.

Zillow's observed rent index and the CPI shelter index are different measurements built for different purposes, as described above, and the comparison in this article is offered as context rather than as a like-for-like gap. Zillow's figures are its own estimates and are subject to revision.

CPI figures are revised. Seasonal adjustment factors are recalculated annually and can change previously published monthly changes.

The Producer Price Index figures cited are from the separate August 2026 PPI release of September 10, 2026. Producer and consumer price indexes measure different transactions at different stages and do not map onto one another.
