The Bureau of Economic Analysis’s first guess at real GDP annualized growth in Q1:2023 was a paltry 1.1%. Bear in mind that the BEA does not yet have March 2023 data for business inventories, net exports or construction expenditures. With only full January and February inventories data, the estimated change in real business inventories in Q1 “contributed” minus 2.3% to the annualized percent change in Q1 real GDP. Who knows, perhaps the March inventories data will reduce the magnitude of the drag on real GDP growth from this component.
In contrast to the drag on Q1 real GDP growth from real business inventories, real Personal Consumption Expenditures (PCE) contributed 2.5% to Q1 annualized real GDP growth. At an annualized rate, Q1 real PCE increased 3.7% versus 1.0% in Q4:2022 and the fastest growth in real PCE since the 12.1% recorded in Q2:2021. Given that real PCE accounted for around 71% of real GDP in Q1, the economy seemingly was on fire in Q1, right?
Wrong! Let’s take a look at the behavior of monthly real PCE as compared to its quarterly average. This is shown in Chart 1 below. The blue bars in Chart 1 represent the month-to-month annualized percent changes in real PCE. The red bars represent the quarter-to-quarter annualized percent changes in real PCE. So, the annualized growth of 3.7% in real PCE in Q1:2023 was the result of the outsized 17.6% annualized growth in January 2023 PCE growth. Monthly real PCE contracted in February and March 2023. In fact, real PCE contracted in four of the past five months. It seemed as though a myriad of measures of economic activity were very strong in January, very strong, as a former president might say. Could it have been that January 2023 was uncharacteristically warm?
