US Economy Grows 3.4% in Third Quarter as Investment Surges, While Fed Holds Rates on Stubborn Inflation

WASHINGTON, 29 October 2026 — The United States economy grew at a 3.4% annualised rate in the third quarter of 2026, its fastest pace in a year, as surging business investment and resilient consumer spending outweighed higher oil prices and a widening trade gap, according to the advance estimate published on Thursday by the Bureau of Economic Analysis (BEA).

The reading came a day after the Federal Reserve held its benchmark rate at 3.75–4.00%, saying inflation "remains elevated."

What Happened

Real gross domestic product increased at a 3.4% annualised rate in the July–September quarter, the Commerce Department's BEA said on Thursday, 29 October. That beat the 3.2% pace forecast by economists polled by Reuters and accelerated from 2.2% in the second quarter.

Investment did most of the heavy lifting. Gross private domestic investment surged 19.4%, against 4.6% in the second quarter, the BEA reported. Equipment spending rose 20.9%, up from 13.4%, led by information-processing equipment — mainly computers and peripherals — a pattern widely linked to the AI infrastructure build-out. Intellectual property products rose 8.4% and structures 5.4%, while residential investment contracted 3.3%.

Private inventory investment added 1.61 percentage points to growth, with wholesale trade and manufacturing leading the build-up. Consumer spending, which accounts for more than two-thirds of the economy, rose 3.8% — the same pace as in the second quarter — on both goods and services.

Trade was a drag: exports fell while imports, which are subtracted in the GDP calculation, increased. Economists surveyed by Reuters had estimated the trade shortfall subtracted at least 4 percentage points from growth. Government spending also added to growth.

Background

The report landed less than a week before midterm elections on Tuesday that will determine control of Congress, and its strength contrasted sharply with households' downbeat mood, Reuters noted, reflected in President Donald Trump's record-low approval ratings and a sharp deterioration in consumer sentiment.

Reuters reported that households have been saving less and dipping into savings to fund spending, while average petrol prices remained above $4 a gallon as the US-Israeli war with Iran dragged on.

The policy backdrop is equally important. The Fed raised rates by a quarter point in September — its first increase since July 2023, approved unanimously — taking the target range to 3.75–4.00%. On Wednesday, 28 October, the Federal Open Market Committee left that range unchanged in a 10–2 vote. Governor Lisa Cook and Cleveland Federal Reserve President Beth Hammack dissented, each preferring a quarter-point increase.

The committee said activity had expanded at a strong pace, spending had been resilient and job gains had kept pace with workforce growth. "The accumulation of more information will help the Committee determine the policy stance appropriate to ensure a timely return of inflation to the Committee's 2% goal," it said. Fed Chair Kevin Warsh told reporters that "economic activity is expanding at a strong pace," while noting that "while uncertainty remains, owing in part to geopolitical developments, domestic spending has been resilient." Reuters reported that economists expected the Fed to raise rates in December.

Why It Matters

The headline figure matters because it runs well above the pace of around 2% that some Fed officials regard as non-inflationary, Reuters noted — leaving the Fed torn between easing too soon and entrenching price pressures, or tightening further and squeezing households facing high energy costs.

The composition of growth matters too. Some economists cautioned, according to Reuters, that given the dominance of AI-related spending, the strong GDP figure was probably not a true picture of the broader economy, and heavily borrowed AI investment could fade if payoffs disappoint.

For households, the gap between data and sentiment is the story: growth is strong, yet many feel worse off, squeezed by energy and food prices. Internationally, the International Monetary Fund noted on Thursday that both the Fed and the European Central Bank had left rates unchanged this week amid high uncertainty. IMF spokesperson Julie Kozack told reporters the Fed was "appropriately remaining data dependent while it's acknowledging the continued strength of the US economy and the upside risks to inflation," adding that US headline inflation remained above the Fed's 2% target.

What Happens Next

The advance estimate is the first of three readings, with revisions due 25 November and 23 December 2026. The Fed's next meeting, on 8–9 December, will include updated projections and is now the key decision point.

Investors will watch whether spending holds its pace as households draw on savings, whether the inventory build-up unwinds, and whether oil prices ease. For now, the US economy finished the summer growing faster than expected, the Fed chose to wait, and the next data on inflation, jobs and spending will decide whether that patience was justified.

FAQ

How fast did the US economy grow in the third quarter of 2026?

Real GDP increased at a 3.4% annualised rate in the July–September quarter, according to the BEA's advance estimate published on 29 October 2026 — up from 2.2% in the second quarter and above the 3.2% forecast in a Reuters poll of economists.

What drove the acceleration in growth?

Investment led the way: gross private domestic investment surged 19.4%, equipment spending rose 20.9% on demand for computers and related equipment, and inventory investment added 1.61 percentage points. Consumer spending, up 3.8%, also contributed, while falling exports and rising imports partly offset the gains.

What did the Federal Reserve decide on interest rates?

On 28 October 2026, the Fed held its benchmark rate at 3.75–4.00% in a 10–2 vote, saying inflation "remains elevated." Governor Lisa Cook and Cleveland Fed President Beth Hammack dissented, preferring a quarter-point increase. The decision followed a quarter-point rise in September.

Why did the Fed hold rates despite strong growth?

The committee said it wanted more information before judging the stance needed to return inflation to its 2% goal. The IMF said on 29 October that the Fed was "appropriately remaining data dependent."

What should we watch next?

Revised GDP estimates are due on 25 November and 23 December 2026, and the Fed's next meeting is scheduled for 8–9 December, with updated projections. Inflation, jobs and consumer spending data in the coming weeks will shape whether the Fed raises rates in December.
