Economists missed the mark. The consensus expected an increase.The BEA reports Real Gross Domestic Product (GDP) increased at an annual rate of 1.6 percent in the first quarter of 2026 (January, February, and March). In the fourth quarter of 2025, real GDP increased 0.5 percent.In the advance estimate, the BEA reported 2.0 percent growth. The Econoday consensus was an upward revision to 2.1 percent.Real First-Quarter GDP and GDIReal GDP 1.6 percent, down from 2.0%Real Final Sales: 1.5% down from 1.6%Real Final Private Domestic Sales: 2.4% down from 2.5%Real Final Domestic Sales: 2.7% down from 2.8%Real GDI: 0.9% vs N/AReal Gross Domestic Income (GDI) is not available in the advance (first) release of the quarter.The difference between real GDP and Real Final Sales is Change In Private Inventories (CIPI) that nets to zero over time.Thus real final sales are a better measure than the topline widely reported numbers.The Fed focuses on Real Final Private Domestic Sales which was a solid 2.7 percent.GDP vs GDIGDP and GDI are two measures of the same thing. Income from sales should match products produced.The BEA calls the difference a “Statistical Discrepancy“.Since the fourth quarter of 2022 GDP has been consistently above GDI.Is income understated or is GDP overstated? It could be a little of each. It could be tax evasion and the underground economy.Tax evasion creates unreported income (missing from GDI) and under-the-table transactions (missing from GDP).I side with the economists who think GDI is a better set of numbers, but not if the answer is tax evasion and unreported income.Contributions to GDPPercentage Point Contributions to 2026 Q1 GDP, Advance EstimateContributions to GDP ProgressionPCE Services: 0.86 PP down from 1.11 PPPCE Goods: 0.09 PP up from -0.03 PPGovernment: 0.73 PP unchangedResidential Investment: -0.24 PP up from -0.31 PPNonresidential Investment: 1.35 PP down from 1.39 PPCIPI: 0.08 down from 0.40 PPExports: 1.34PP up from 1.32 PPImports -2.59 PP up from -2.62 PPHuge DistortionsGovernment spending was a rebound from the shutdown in the fourth quarter of last year.The surge in imports was related to the Supreme Court Tariff decision. Importers waited for the ruling then pounced when it happened.It’s important to note that imports don’t add or subtract to GDP. The D in GDP explains why.The BEA subtracts imports because they assume all sales are domestic. Otherwise the BEA would be trying to figure out things like “What percentage of this hammer from Home Depot is Domestic?”Net exports were an anemic -1.25 percentage points, but tariff distortions are in play.Strip out government spending, and you are at 0.87 percent. That 0.73 PP contribution from government won’t be repeated.I expect more negative revisions. They tend to feed on each other.Original Post
