- The boost in the headline number resulted from upward revisions to contributions from consumer spending (+0.17%) and inventories (also a +0.17% increase, as a result of reportedly slower inventory contractions). No other line items changed materially.
- The BEA's "bottom line" for the quarter (their "Real Final Sales of Domestic Product", which excludes inventories) increased to +3.41%, up +0.18% from the previous estimate and +1.04% from the prior quarter.
- Real annualized household disposable income decreased -$2 per year from the previous report to $39,223 (in 2009 dollars). The household savings rate deteriorated to 2.6%, lower than the level recorded in third quarter of 2007 -- at the onset of the "Great Recession."
- For this revision the BEA assumed an effective annualized deflator of 2.35%. During the same quarter (October 2017 through December 2017) the inflation recorded by the Bureau of Labor Statistics (BLS) in their CPI-U index was a very similar but slightly higher 2.49%. Under estimating inflation results in optimistic growth rates, and if the BEA's "nominal" data was deflated using CPI-U inflation information the headline growth number would have been slightly lower at a +2.82% annualized growth rate.
Hurricane spending undoubtedly boosted fourth-quarter GDP, and consumers had to tap into saving to buy.
Retail sales have not been good so far in 2018 so expect a snapback in the first quarter.
