The latest US GDP figure is severely skewed by the government shutdown.

Let's break down the GDP numbers to see what had happened.

GDP growth = G + I + C + NE

Q2 GDP (Final estimate) = (-0.01) + (-2.66) + 1.68 + 4.83 = 3.84 (3.8)

Q3 GDP (First estimate) = 0.39 + (0.02) + 2.39 + 1.59 = 4.35 (4.3)

We can ignore this fantastic GDP headline figure because it is heavily skewed by the US government shutdown.  Many micro GDP component data had been skewed and these skewed data had caused the headline GDP figure to spike.  The next GDP figure will crash because of this skewed effect.
