Writers have often used mechanical terms to describe the economy. In a machine, cause leads to effect because of fixed mechanical linkages within the system. In the economy, movements in one variable often seem to have an effect on other variables, much like in a machine. This way of thinking has implications for policy because if you understand how the levers and dials on the machine work, you know which lever to pull to get the desired result.
However tempting it is to use this mechanical metaphor, in the real economy correlation does not always mean causation. Relationships thought to be stable can break down. The current economic environment is exhibiting behavior that does not fit the old models. As a result, policy implications are clouded, and predictions come with more uncertainty. Better explanations are needed, but first we need to describe what has changed and where the old linkages are failing. One of those old linkages is the correlation between GDP growth and employment growth. Simply put, GDP growth has been quite strong while employment growth has lagged--creating a so-called "jobless boom." It is worth spending some time looking at potential explanations for this unusual series of events.
At the time of our last Quarterly Market Report, we did not yet know the real GDP growth rates for the 3rd quarter of 2025 because of the lapse in government appropriations. The Atlanta Fed's nowcast of 4.2% at that time seemed optimistic, with the Blue Chip consensus closer to 3%. One open question was how large the inventory drawdown would be. While this is not always a complicated or consequential issue, answering this question is more complicated today because of the volatility introduced by tariffs. Inventories spiked in advance of the tariffs and have been drawn down over time. As it turned out, inventories were hardly drawn down at all (-0.12%) in the 3rd quarter. Consequently, 3rd quarter real GDP growth came in at a very strong 4.4% (all growth rates of GDP and its components in this report are expressed as a seasonally adjusted annual rate).
Real GDP growth in the 4th quarter was 1.4%, down significantly from the 3rd quarter, but still quite good for the circumstances. The 4th quarter was hampered by the government shutdown at the beginning of the quarter. Federal government spending fell by 16.6% which took 1.15 percentage points off of the overall real GDP growth rate. Without the drop in federal spending, real GDP growth would have been closer to 2.5% which is close to the recent average. Even so, we ended 2025 with 2.2% real GDP growth--slightly less than the 2.8% in 2024 though better than some forecasters would have expected in light of the tariff announcements early in the year.
