The Atlanta Federal Reserve's quarterly GDP assessment indicates the U.S. economy is tracking toward third-quarter expansion of 3.5%, revised downward from an earlier 3.6% projection. The GDPNow model, a key forecasting tool maintained by the Atlanta Fed, continuously monitors economic indicators to refine its US growth estimates. This latest downward adjustment reflects recent economic data inputs and represents the central bank's most current assessment of American economic momentum for the period.
