The United States Bureau of Economic Analysis will release its advance estimate of first-quarter 2026 gross domestic product on Thursday, with economists broadly forecasting a significant deceleration from the 2.4% annualised growth recorded in Q4 2025. Wall Street consensus estimates have clustered around 0.4% to 0.8% annualised growth, with some forecasters warning of a technical contraction, as a surge in imports ahead of sweeping tariff increases artificially inflated the trade deficit and subtracted sharply from the headline figure.

The anticipated slowdown reflects a confluence of forces that built throughout January, February, and March. Companies across manufacturing, retail, and technology sectors accelerated import purchases in advance of tariff deadlines, a front-loading effect that the BEA's accounting methodology records as a drag on GDP even when domestic demand remains relatively firm. Business fixed investment is also expected to have softened materially, as corporate executives delayed capital expenditure decisions amid unresolved trade policy uncertainty emanating from Washington.

Consumer spending, which accounts for roughly two-thirds of US economic output, is expected to have held up better than the headline number suggests, providing some reassurance to Federal Reserve officials monitoring whether the slowdown is transitory or indicative of a deeper demand problem. Personal consumption expenditure data released earlier this week pointed to resilient household spending through March, though analysts caution that tariff-driven price pressures are beginning to erode real purchasing power for lower- and middle-income households.

Financial markets are bracing for a volatile reaction to the release. Equity futures traders have priced in a wide range of outcomes, and bond markets have already shifted toward pricing in two Federal Reserve rate cuts before year-end should the GDP print come in at or below zero. Fed Chair Jerome Powell is not scheduled to speak Thursday, but investors will parse the data closely ahead of the Federal Open Market Committee's May meeting for signals about the central bank's tolerance for growth-inflation trade-offs under the current tariff regime.

The GDP release will land alongside a busy day of corporate earnings, with several major companies in the energy, consumer staples, and industrial sectors reporting first-quarter results. Analysts expect the macro data to overshadow individual earnings beats or misses, potentially setting the tone for markets heading into the final trading day of April. Treasury Secretary Scott Bessent is expected to comment on the figures, likely emphasising that the import surge reflects one-time adjustments rather than structural weakness, a line of argument the White House has previewed in recent days.
