Personal consumption expenditure (PCE) contributed 1.46 percentage points to growth (2.04 percent in Q3) and rose at a slower 2.2 percent (3 percent in Q3). Spending on both durable goods (4.3 percent from 6.6 percent in Q3) and nondurable goods (1.5 percent from 4.2 percent in Q3) grew at a slower pace and consumption in services also increased less (2 percent from 2.1 percent).
Fixed investment added a meager 0.03 percentage points to growth (0.6 percent in Q3) and expanded 0.2 percent (3.7 percent in Q3). Nonresidential investment shrank 1.8 percent, following a 2.6 percent gain in the previous period, mainly due to lower structures (-5.3 percent from -7.2 percent in Q3) and equipment investment (-2.5 percent from 9.9 percent in Q3). Residential investment increased 8.1 percent, the same as in the previous period.
Private inventories subtracted 0.45 percentage points from the growth, lower than 0.71 percent in the previous quarter.
Meanwhile, exports shrank 2.5 percent, after a 0.7 percent rise in the third quarter and imports rose at a slower 1.1 percent (2.3 percent in Q3), bringing the impact from trade to -0.47 percentage points (-0.26 in Q3).
