Consumer prices rose 0.4% in August and 3.4% over the past twelve months, the Bureau of Labor Statistics reported Friday, September 11, 2026. Core inflation—which strips out volatile food and energy—accelerated 0.3% for the month, a tenth of a percentage point higher than economists expected, while the annual core rate stood at 2.4%.
Underneath the headline numbers, core inflation remained mixed with modest goods inflation, continued shelter disinflation, but strong services excluding shelter inflation—a category economists call “supercore”—suggesting that underlying inflationary pressures continue to be sticky and the Fed will have to hike in order to help inflation return toward the 2% target. The report comes as the 10-year Treasury yield approaches 5% and mortgage rates hover around or above 7%, adding pressure to an already affordability-constrained housing market.
Traders responded to the report by increasing odds for a Fed rate hike next week. The next FOMC meeting is September 15–16, 2026, with the Federal Reserve scheduled to announce its interest rate decision on Wednesday, September 16, 2026 at 2:00 PM ET.
The numbers
What drove August inflation higher
Energy prices surged while services costs remained stubbornly elevated
Gasoline prices surged 3.9% in August after falling 2.9% in July and were 27.4% higher than a year earlier, with gasoline prices accounting for over one third of the monthly all items increase. The broader energy index, which includes gasoline, electricity and fuel oil, rose 2.1% in August after falling 1.5% in July, and compared with a year earlier, energy prices increased 16.3%, versus a 14.7% annual rise in July.
Housing prices rose 0.3% in August while the shelter index is 3% higher than a year ago, and tenants’ and household insurance costs were unchanged on a monthly basis but are up 4.1% compared with last year. Transportation services prices increased 0.5% on a monthly basis and are up 2.4% from last year, with airline fares rising 2.7% in August and up 23.4% compared with a year ago amid higher jet fuel costs.
The official data is available on the Bureau of Labor Statistics website, where the agency publishes detailed tables and historical data each month.

Market reaction
What this means for mortgage rates and Fed policy
Borrowing costs climb as central bank weighs next move
“Chair Warsh and others signaled that interest rates can remain on hold only if disinflation continues and today’s August report did not deliver that,” said Kathy Bostjancic, chief economist at Nationwide. “Further, the renewed march higher in oil, gasoline and diesel prices add to concerns that higher energy prices could spill over to other goods and services and inflation expectations.” Nationwide now expects a quarter-point hike next week.
The fed funds rate, a benchmark for multiple consumer loans, is currently pegged in a range of 3.5%-3.75%, where it has been for all of 2026. The Fed policy committee voted 9-3 to keep rates at 3.5%-3.75% at its July meeting in the face of inflationary pressures, with dissenting votes raising pressure for a September rate hike.
According to Freddie Mac’s Primary Mortgage Market Survey released September 11, 2026, the 30-year fixed-rate mortgage averaged 6.76%, up 0.05 from the prior week, while the 15-year fixed-rate mortgage averaged 6.09%, also up 0.05 from the prior week. According to average rates from the Zillow lender marketplace, the current 30-year fixed rate on Saturday, September 12, 2026, rose by 8 basis points to 6.91%, marking the second consecutive day of increases.
For homebuyers, this means mortgage financing remains expensive by recent historical standards, and any Fed rate hike next week would likely push borrowing costs even higher. If you’re shopping for a home, understanding what you can actually afford in this rate environment is critical.
The Fed meeting timeline
The September 2026 FOMC meeting is September 15-16, 2026, with the Fed interest rate decision announced Wednesday, September 16, 2026 at 2:00 PM ET, along with the Summary of Economic Projections (dot plot). FedWatch predicted Monday that there’s a 66% chance the Federal Open Market Committee will hike by a quarter-point at its upcoming September meeting.
For buyers
What to do if you’re trying to buy a house right now
Higher rates don’t mean you should stop looking—but your strategy matters
Persistent inflation and the prospect of higher Fed rates mean mortgage costs are unlikely to fall meaningfully in the near term. Expect rates to hover between 6% and 7%, though the sub-3% rates of the coronavirus pandemic era likely aren’t coming back. That doesn’t mean you should wait indefinitely—home prices and competition may increase if and when rates eventually decline, which can offset the benefit of waiting.
If current rates put homeownership out of reach, explore down payment assistance programs and zero-down loan options that can lower your upfront costs. Many first-time buyer programs offer interest rate subsidies or grants that effectively reduce your borrowing cost. Even buyers with less-than-perfect credit have options, though rates will be higher.
Shop your rate aggressively. In a volatile market, lenders’ pricing can vary by half a percentage point or more for the same borrower profile. Get quotes from at least three lenders within a 14-day window (multiple mortgage inquiries within that span count as a single credit pull). Lock your rate when you’re satisfied, especially if the Fed hikes next week as expected.
Consider an adjustable-rate mortgage (ARM) if you don’t plan to stay in the home long-term. The 5/1 ARM averaged 6.85% on September 12, 2026, which can offer modest savings over a 30-year fixed rate, though you’ll face rate-adjustment risk after the initial period. Run the numbers carefully and understand the caps and adjustment schedule before committing.
Quick answers
Inflation and mortgage rates: common questions
Why does inflation affect mortgage rates?
Mortgage rates track long-term bond yields, especially the 10-year Treasury. When inflation runs hot, bond investors demand higher yields to compensate for the loss of purchasing power over time. Lenders then pass those higher yields on to mortgage borrowers. Persistent inflation also raises the odds that the Federal Reserve will hike short-term rates, which indirectly pushes mortgage rates higher by making bonds less attractive and increasing the cost of funding for lenders.
Will the Fed definitely raise rates at the September meeting?
Market pricing via FedWatch shows a 66% chance the Federal Open Market Committee will hike by a quarter-point at its September 15-16 meeting. The August CPI report increased those odds, but the decision isn’t final until the committee votes. Fed Chair Kevin Warsh has signaled that rates can remain on hold only if disinflation continues, and the August data showed core inflation accelerating on a monthly basis, not slowing.
What is “core” inflation and why does it matter more than the headline number?
Core inflation excludes food and energy prices, which swing wildly month to month due to weather, geopolitics, and seasonal factors. The Federal Reserve watches core inflation closely because it better reflects underlying price trends and is a more reliable signal of whether inflation is truly cooling. In August, core CPI rose 0.3% monthly—higher than the 0.2% economists expected—which is why markets reacted negatively even though the headline 3.4% annual rate was in line with forecasts.
How much does shelter inflation contribute to overall CPI?
Shelter is the single largest component of the CPI at 35%. Housing prices rose 0.3% in August while the shelter index is 3% higher than a year ago. Because shelter is measured using a lagging methodology—it tracks rents signed months ago and owners’ equivalent rent, not current market rents or home prices—shelter inflation can stay elevated even after the housing market cools. That lag is one reason overall inflation remains sticky.
Should I wait to buy a house until rates come down?
There’s no guarantee rates will fall soon, and waiting carries its own risks. If the Fed holds rates steady or cuts later, demand could surge and push home prices higher, erasing any savings from a lower rate. A better strategy: buy when you find the right home at a price you can afford, then refinance if rates drop meaningfully in the future. Focus on your monthly payment, total cost of ownership, and whether the home fits your long-term needs, not on timing the market perfectly.
What’s the difference between the Fed rate and mortgage rates?
The Federal Reserve sets the federal funds rate, which is the overnight rate banks charge each other. Mortgage rates, by contrast, are long-term rates tied to the 10-year Treasury yield and influenced by inflation expectations, economic growth, and global demand for U.S. bonds. A Fed rate hike doesn’t directly raise mortgage rates one-for-one, but it signals tighter monetary policy and often pushes bond yields—and therefore mortgage rates—higher. The two move in the same general direction but at different speeds and magnitudes.
