US Q3 GDP has been revised lower to 4.9%, slightly below 5.2% in the second estimate, but matching the 4.9% initially reported in the advance estimate. The estimate released today is based on more complete source data than were available for the “second” estimate issued last month. The downgrade primarily reflected a downward revision to consumer spending. Imports, which are a subtraction in the calculation of GDP, were revised down as well.
