What is US Gross Domestic Product?

Gross domestic product is the broadest measure of economic output, capturing the total monetary value of all goods and services produced within the United States over a given period. The BEA publishes GDP estimates on a quarterly basis, with three successive releases for each quarter: the advance estimate (approximately one month after the quarter ends), the second estimate (roughly two months after quarter-end), and the third and final estimate (approximately three months after quarter-end).

The second estimate incorporates more complete source data than the advance, including updated figures on consumer spending, business investment, and trade. Revisions between the advance and second estimates can be significant, particularly when incoming data on retail trade, services, and inventories shift materially. The BEA’s GDP figures are widely regarded as the definitive scorecard for the health of the US economy and inform Federal Reserve policy, fiscal planning, and global investment decisions.

Each quarterly GDP release measures activity on an annualised basis, meaning the quarterly rate of change is projected over four quarters. A reading of 1.6% means that if the economy continued at Q1’s pace for a full year, GDP would expand by 1.6%.

Q1 2026 GDP Second Estimate: May 28, 2026

The BEA’s second estimate confirmed that real GDP grew at an annualised rate of 1.6% in the January-to-March quarter, revised down from the 2.0% advance reading released on April 30, 2026. The revision reflected downward adjustments to both consumer spending and private investment.

Personal consumption expenditures, which account for roughly 70% of GDP, were revised down to a growth rate of 1.4% from the previously reported 1.6%. The revision to consumer spending was driven by a downward adjustment to services expenditure, partially offset by an upward revision to goods spending. Nonresidential fixed investment growth was revised slightly lower to 10.1% from 10.4%, primarily reflecting slower growth in intellectual property products. Residential investment, however, came in better than initially estimated, with the decline revised to -6.2% from the advance’s -8.0%.

Government spending was unchanged at 4.4% growth, providing a solid contribution to overall activity. Exports contributed positively to the headline figure, while the increase in imports, which subtract from GDP in the national accounts, weighed on the overall result.

Corporate Profits

The second estimate also included the first reading of Q1 2026 corporate profits. Profits from current production rose by $40.4 billion in the first quarter, a sharp deceleration from the $246.9 billion increase recorded in the fourth quarter of 2025. The slowdown in profit growth reflected a combination of higher input costs, softer consumer demand, and the lingering effects of tariff-related uncertainty on business margins.

Domestic profits fell across both the financial and non-financial sectors, while profits from the rest of the world held roughly steady. The weak corporate profit reading raised concerns about forward earnings guidance for 2026, adding a cautionary note to an otherwise resilient equity market.

Historical Context

The 1.6% second estimate marked a recovery from Q4 2025’s 0.5% reading but remained well below the pace seen during the mid-2025 rebound. The prior two years had exhibited significant volatility in quarterly growth, with contractions and sharp rebounds reflecting the effects of fiscal policy changes, tariff disruptions, and fluctuating consumer confidence.

Why the Revision Mattered

A downward revision of 0.4 percentage points from the advance to the second estimate was notable given that consensus had expected a slight upward revision to around 2.1%. The miss suggested that the initial April reading had overstated underlying momentum, particularly in consumer-facing services. With the PCE price index holding at 4.5% and core PCE revised up 0.1 percentage point to 4.4%, the simultaneous picture of slower growth and persistently elevated inflation added complexity to the Federal Reserve’s policy calculus.

The data contributed to an ongoing debate among economists about the risk of stagflation: growth running below potential while inflation remained well above the Fed’s 2% target. Corporate profits slowing sharply in the same quarter added a further cautionary signal about the sustainability of the equity market’s 2025-2026 rally.

For the Federal Reserve (the Fed), the second estimate reinforced the case for keeping rates on hold. Cutting rates with inflation at 4.5% would risk entrenching price expectations; raising them with growth at 1.6% and corporate profits under pressure would risk tipping the economy into contraction. The FOMC rate decision on June 17-18, 2026 was widely expected to result in another hold, with the Fed watching subsequent data for clearer signals of either disinflation or a growth deterioration.

Market Reaction

US equity indices rose modestly following the 08:30 EDT release on May 28. The S&P 500 gained approximately 0.44% to around 7,553 in mid-morning trading, and the Nasdaq Composite advanced by a similar margin. However, analysts noted that the rally could not be attributed solely to the GDP and PCE data, as geopolitical headlines related to a potential US-Iran agreement were also circulating at the same time.

Bond markets reflected a more cautious read. Treasury yields eased modestly on the softer growth figure, with the 10-year yield declining a few basis points. The market interpretation was that weaker-than-expected GDP reduced the probability of a Fed rate hike, even as inflation remained uncomfortably high. The US dollar weakened slightly against major currencies in the immediate aftermath of the release. Commodities were broadly steady, with gold ticking higher as real yields declined marginally.

Options markets had not priced in a significant downside surprise of this magnitude in the GDP figure, and the reaction was therefore somewhat muted relative to the degree of the miss. Traders appeared willing to look through the revision, focusing instead on the simultaneous upcoming June inflation data as the more critical determinant of near-term Fed policy.

Related Events

• FOMC Rate Decision June 2026 – The Fed’s June meeting considered the Q1 GDP revision and persistent inflation in determining whether to hold, hike, or cut the federal funds rate.
• US CPI Report June 2026 – The June Consumer Price Index release provided an updated inflation reading that markets were watching alongside GDP data to assess the broader economic trajectory.
• US Employment Situation June 2026 – The June non-farm payrolls report offered a complementary view of economic health alongside the GDP revision, particularly regarding labour market resilience.

Frequently Asked Questions

What did the Q1 2026 GDP second estimate show?

The BEA’s second estimate, released on May 28, 2026, showed that the US economy grew at an annualised rate of 1.6% in Q1 2026, revised down 0.4 percentage points from the advance estimate of 2.0% published in April. The revision was driven by downward adjustments to consumer spending and nonresidential fixed investment.

Why was the actual result lower than the consensus forecast?

The consensus forecast, according to the Action Economics Forecast Survey, anticipated a slight upward revision to approximately 2.1%. The actual result fell short primarily because incoming data on services consumption and business investment came in weaker than the source data available at the time of the advance estimate. These revisions are normal and reflect the BEA incorporating more complete reports from government agencies and private surveys.

What does the 1.6% GDP reading mean for Federal Reserve policy?

The combination of 1.6% GDP growth and a PCE price index of 4.5% left the Federal Reserve in a difficult position. Growth at this level does not signal an imminent recession, but it is below the Fed’s long-run estimate of potential growth of around 1.8-2.0%. With inflation more than double the 2% target, the Fed faced pressure to keep rates elevated, and the second GDP estimate reinforced expectations that the June 2026 FOMC meeting would result in rates being held unchanged.
