GDPNow Nowcast
Education only · our voice · free public data
Definition
A running, model-based estimate of the current quarter's real GDP growth that updates as each economic data release arrives — a real-time read on the economy before official figures print.
How to read it
GDPNow (produced by the Federal Reserve Bank of Atlanta) mechanically translates incoming data (retail sales, trade, construction, inventories, etc.) into an evolving annualized GDP estimate. It is a nowcast, not a forecast: early-quarter readings are noisy and swing on single releases, tightening as the quarter fills in. Its value is the trajectory and the gap versus consensus — a nowcast drifting well above or below Wall Street forecasts flags data momentum the market may not have priced.
How practitioners use it
Used as context among multiple indicators — never as a standalone signal to act.
Less common professional uses
Use the nowcast's residual versus consensus as a growth-surprise proxy that front-runs the Citi/Bloomberg surprise indices, which lag official prints. Cross-check the nowcast against curve steepness and credit — a rising nowcast into a re-steepening curve is a coherent reflation signal; a rising nowcast while credit widens is a low-quality growth impulse. Decompose the nowcast: growth carried by inventories or net exports is lower-quality than growth led by final domestic demand, and mean-reverts faster.
