Real GDP measures the total value of goods and services produced in the US economy, adjusted for inflation — the most comprehensive single measure of economic size and growth. Two consecutive quarters of declining real GDP constitute a technical recession, making this the definitive benchmark for identifying economic cycle turning points. GDP is reported quarterly with multiple revisions as more complete data becomes available, meaning the initial estimate carries significant revision risk. The composition of growth matters as much as the headline: consumer spending-led growth has very different implications than inventory-led growth, and government spending contributions can obscure underlying private sector weakness. The Fed, financial markets and corporate planning all use real GDP growth as the fundamental economic baseline for decision-making. For investors, real GDP growth rate determines the broad environment for earnings growth across the market: nominal revenues typically grow in line with nominal GDP over time, so sustained above-trend GDP growth supports equity multiples while contraction triggers earnings revision cycles. The trend growth rate — currently estimated around 1.8-2.0% for the US — provides the reference point against which actual growth is measured, with periods of above-trend growth gradually consuming economic slack and building inflationary pressure.
