Q2 GDP Held at 1.5% Then Jumped to 2.2% as PCE Inflation Cooled

A headline number that held still, and then moved

In late August, the Bureau of Economic Analysis left its figure for U.S. growth in the second quarter of 2026 unchanged. Its second estimate put real GDP growth at an annualized 1.5% for April through June, the same as the advance reading, after 2.1% in the first quarter.1 The agency said the revision was downward by less than a tenth of a percentage point. A larger estimate of consumer spending was mostly cancelled out by a larger estimate of imports.1

That stable headline lasted about five weeks. On September 30, the third estimate raised second-quarter growth to 2.2%, a jump of 0.7 percentage point. It also lowered the main inflation measures for the quarter.12 Looking back from mid-October, the August release matters less for its growth figure than for what it shows about how a single quarterly number can steer the debate over stagflation in the wrong direction.

What the August estimate actually said

The 1.5% figure hid a lot of strength inside the economy. Consumer spending, exports and investment all added to growth, while lower government spending held it back. Imports, which are subtracted when GDP is calculated, also rose.1 Consumer spending was revised up to a 3.4% annualized pace from 3.2%. Most of the upgrade came from services, led by health care, partly offset by a downgrade to goods.5 Real final sales to private domestic purchasers, which strips out trade, inventories and government, rose 4.2%, up from 3.9% in the advance estimate.1 By Bloomberg's count, cited by Quartz, that was the strongest pace in more than three years.5

The price side was the problem. The PCE price index rose at an annualized 5.3%, revised up 0.2 point. Core PCE, which leaves out food and energy, was revised up to 3.6%.1 The price index for gross domestic purchases rose 5.8%.1 Put next to 1.5% real growth, those numbers described an economy that was barely growing while prices rose sharply. One housing-market analysis of the August release argued that the inflation figures mattered more than the growth figure, because they showed price pressure that had not eased.

Another part of the same release pointed the other way. Real gross domestic income, which measures the economy from the income side, rose 2.2% in the second quarter. The average of GDP and GDI came to 1.8%.1 That gap was an early sign that the 1.5% headline was too low.

Why the headline understated demand

Coverage of both the advance and second estimates agreed on what was holding growth back: imports, mostly tied to spending on artificial intelligence. Investopedia linked the weak headline to imported computer equipment bought during the AI investment boom.10 BEA's advance release said goods imports were led by capital goods, especially telecommunications equipment, semiconductors and industrial equipment.7 The AP later reported that imports grew at a 12.6% annual rate in the quarter and cut almost 1.7 percentage points from growth.8

Government spending also looked weak for a technical reason. BEA explained that the drop in federal nondefense spending mainly reflected sales of crude oil from the Strategic Petroleum Reserve. Those sales count as negative government consumption, but they have no direct net effect on GDP.7 Quartz reported that combined government outlays shrank at a 1% annualized pace.5

Several economists said in July that the headline was misleading. Oxford Economics' Michael Pearce said the 1.5% pace understated the economy's strength because it reflected rising imports and falling inventories, neither of which would last. He predicted inventory rebuilding would push growth back above 2%.3 EY-Parthenon's Gregory Daco pointed to strong consumer spending and AI-related investment in equipment and intellectual property.3 The September revision largely proved them right.

The September revision changed the picture

The third estimate raised real GDP to 2.2%, mainly because investment, consumer spending and government spending were all revised up.12 The first quarter was also raised, to 2.5% from 2.1%, as part of BEA's annual update, which revised data back to early 2021.12 Real final sales to private domestic purchasers rose to 4.6%. GDI was revised up to 2.6%, and the average of GDP and GDI to 2.4%.12

Inflation moved the other way. Second-quarter PCE inflation was cut to 5.0% from 5.3%, and core PCE to 3.3% from 3.6%.12 The gross domestic purchases price index fell to 5.6%. First-quarter core PCE was lowered from 4.4% to 3.9%.12 Current-dollar GDP, which mixes real growth and inflation, was raised to 8.5% from 8.0%.

That combination matters. Verified Investing noted that the revision raised real output and lowered prices at the same time, so more of the economy's nominal growth turned out to be real activity rather than inflation. Its conclusion was that the stagflation reading from the August release was now much weaker.14 By its calculation, the August figures implied a GDP deflator of about 6.4%, while the September figures put it at 6.1%.14 Revisions to third estimates are usually a few tenths of a point, the firm noted, so a 0.7-point change is unusual.14

Where the coverage diverges

Reporting agrees on the official numbers but differs on expectations and meaning.

Forecasts for the advance estimate varied by survey. Fox Business cited a 2.1% consensus from economists polled by LSEG.3 Investopedia cited 1.8% from a Dow Jones and Wall Street Journal survey.10 Either way, July's 1.5% was a miss.

Accounts of the September surprise were more consistent. Trading Economics listed the consensus for the third estimate at 1.5%.2 The Washington Post said economists had expected little or no change.9 Few forecasters saw the upgrade coming.

Some outlets did not keep up with the revisions. DailyForex said second-quarter growth exceeded the first quarter's 2.1%, but the same release had already raised the first quarter to 2.5%, so growth actually slowed slightly.1712 Advisor Perspectives described the second-quarter reading as an acceleration from the fourth quarter of 2025, which is a less useful comparison than the one to the first quarter.6

The sharpest disagreement is about the Federal Reserve. In July, Pearce said nothing in the data would change the Fed's view that the economy was resilient, and that inflation running slightly below expectations supported keeping rates on hold.3 Daco warned that a long escalation of the Middle East conflict could push the Fed toward raising rates again.3 After the September data, DailyForex argued that inflation still well above the Fed's 2% target could require more rate hikes before year-end. It also noted that crude oil was trading near $103 a barrel.17

The inflation backdrop remains the real story

Even with the downward revisions, inflation is not under control. The conflict with Iran raised shipping and energy costs during the quarter, which Quartz linked directly to the slowdown.5 Verified Investing said the deflator rose to 6.1% in the second quarter from 3.2% in the first, and that prices rose faster than real output in five of the last eight quarters.14 Monthly data were more encouraging. Core PCE rose 3.0% from a year earlier in August, below the 3.3% that markets expected.17

In my view, both main narratives miss part of the picture. The August reading of a stalling economy with high inflation was mostly a measurement problem: import surges, inventory swings and oil-reserve accounting pulled down the headline while private demand grew at its fastest pace in years. The September reading of a healthy economy also needs a caveat. An annualized 5% rate of consumer inflation for the quarter is still far above where the Fed wants it, even after the downgrade, and energy prices tied to the Persian Gulf conflict remain high.1317

The result is an economy with stronger growth than first reported and inflation that is high but not as extreme as the August data suggested. For policymakers, that does not argue for cutting rates. Strong private demand alongside core inflation above 3% supports either holding rates or tightening further.

What comes next

The next test is October 29, when BEA publishes its advance estimate for third-quarter GDP together with September PCE data.142 Trading Economics expects growth of about 0.9% for the third quarter.2 If that happens, the debate over a slowdown will return, although the second-quarter experience shows that early estimates can understate growth by a wide margin.

The price data may matter more than the growth figure. If the deflator falls back to the 3% to 4% range, the second quarter's spike looks like a one-off driven by energy and tariffs. If it stays above 5%, the economy is running hot on both growth and prices, which would make bond markets and Fed officials more uneasy.14 August's 1.5% reading did not mean the economy had stalled. It was an early figure that pointed analysts toward the wrong conclusion.
