Why Q3 GDP Grew 3.4% Annualized While Inflation Slowed in the Same Quarter

The Bureau of Economic Analysis reported on Oct. 29, 2026 that real gross domestic product rose at an annual rate of 3.4% in the third quarter of 2026, up from 2.2% in the second quarter. The figure is the advance estimate, the first of three releases for the quarter, and it covers July through September.

The same day, the agency's personal income report for September showed spending rising. The GDP report also showed prices rising more slowly than in the second quarter. The Federal Reserve's statement of Oct. 28, 2026, issued one day earlier, described activity as expanding at a strong pace while inflation remained elevated. Faster output and slower price growth arrived in the same quarter.

What Drove the 3.4% Headline

Real GDP rose 0.8% at a quarterly rate in the third quarter, which BEA expresses as 3.4% at an annual rate, according to its Oct. 29 release. Current-dollar GDP rose 5.6%. Real final sales to private domestic purchasers rose 4.9%, compared with 4.6% in the second quarter.

Consumer spending, business equipment, inventories and government spending all added to growth in the advance estimate. Exports decreased, and imports increased. Imports are subtracted in the GDP calculation, so the trade pattern weighed on the headline even as domestic demand grew.

Within consumer spending, services gains were led by health care and by food services and accommodations. Within goods, the largest gain came from other nondurable goods, mainly prescription drugs.

Taken together, the quarter shows total output growing faster than in the second quarter, while private domestic final sales also accelerated, from 4.6% to 4.9%.

Trade, Inventories and Government Spending

Exports decreased in the third quarter, led by petroleum and related products. Imports increased, with capital goods excluding automotive as the largest contributor. Because imports are subtracted from GDP, that increase reduced the headline figure.

Private inventory investment also increased, led by wholesale trade and manufacturing, mainly nondurable goods. Equipment spending rose, led by information processing equipment, mainly computers.

Government spending increased, driven by federal nondefense consumption. BEA primarily ties that to smaller sales from the Strategic Petroleum Reserve than in the second quarter. BEA says those sales have no direct effect on GDP.

The Monthly Picture From September's Income Data

GDP is reported by quarter. The monthly data released alongside it come from BEA's Personal Income and Outlays report for September 2026, published Oct. 29, 2026.

That report shows personal income up $54.5 billion, or 0.2%, and disposable personal income up $52.7 billion, or 0.2%, for September. Personal consumption expenditures rose $113.1 billion, or 0.5%, in the month.

Personal saving was $911.1 billion, a saving rate of 3.8%. Spending therefore grew faster than disposable income in September, at 0.5% against 0.2%.

The monthly income data and the quarterly GDP estimate are published on the same day, but they cover different periods: one month and one quarter.

The second GDP estimate for Q3 2026 is scheduled for Nov. 25, 2026 at 8:30 a.m. EST. It will also include corporate profits. BEA says that release will replace the figures published Oct. 29.

How BEA Revises Its Early Estimates

BEA publishes three estimates for each quarter. The advance estimate comes near the end of the first month after the quarter ends. It is based on source data that are incomplete or subject to further revision by the source agency.

The second estimate, released near the end of the second month, and the third, released near the end of the third month, draw on more detailed and comprehensive data. The third estimate also brings in GDP by industry, gross output and GDP by state.

The advance estimate therefore rests on the least complete source data of the three. BEA says annual and comprehensive updates are released in late September.

BEA reports average revisions to quarterly real GDP growth, without regard to sign, for 1996 through 2025. The average is 0.5 percentage point from advance to second, 0.6 point from advance to third, and 0.3 point from second to third, at annual rates.

The second quarter of 2026 shows the pattern. BEA's Survey of Current Business reports that real GDP grew 1.5% in the advance estimate of July 30, 2026 and again in the second estimate of Aug. 26, 2026. The third estimate, released Sept. 30, 2026, raised growth to 2.2%, an upward revision of 0.7 percentage point.

For that reason, the Q2 figure cited in the Oct. 29 release is the third estimate of 2.2%, not the 1.5% first published in July.

Inflation Slowed Within a Faster Quarter

The PCE price index rose at a 2.1% annual rate in the third quarter of 2026, down from 5.0% in the second quarter, according to the advance estimate. Core PCE, which excludes food and energy, rose 2.5% after 3.3% in the prior quarter.

The gross domestic purchases price index rose 3.0% in the third quarter, compared with 5.6% in the second. All of these price figures are annual rates for the quarter.

Headline PCE inflation sat above core in the second quarter, at 5.0% against 3.3%. In the third quarter it sat below core, at 2.1% against 2.5%.

The price figures and the growth figure come from the same release. Growth accelerated in the quarter while both PCE measures slowed.

How the Fed's Stance Frames the Growth Number

On Oct. 28, 2026, the Federal Open Market Committee kept the federal funds target range at 3-3/4 to 4 percent. The statement says the decision is made in support of the Federal Reserve's dual mandate, and that the Committee continues to maintain ample reserves in the banking system.

The statement described economic activity as expanding at a strong pace. It cited resilient domestic spending, strong productivity growth and robust capital investment. Job gains have kept pace with the workforce, and the unemployment rate has changed little.

On inflation, the statement said it remains elevated and that the Committee aims for a timely return to the 2% goal. It described uncertainty as still elevated, partly because of geopolitical developments.

The vote was 10 to 2. Lisa D. Cook and Beth M. Hammack dissented, both preferring a quarter-point increase in the target range. The statement says more information will help the Committee determine the policy stance, and it gives no explicit rate path.

The statement was issued one day before the advance GDP figure was released, so it did not include that figure.
