GDP and Tariffs

Tariffs Main Story, but the GDP Dropped Big Time

3% to 1.5% and the Government Shut Down was at Fault?

 

The big stories in the economy today were tariffs being struck down by the Supreme Court and the GDP coming in at 1.5% instead of 3% for the fourth quarter. The Supreme Court decision on tariffs overshadowed the GDP numbers. The administration quickly suggested the lower GDP numbers were because of the government shutdown. That is not entirely feasible.

A Short Government Shutdown Does Not Cut GDP in Half
If GDP comes in at 1.5% instead of 3%, blaming a shutdown that lasted only a few weeks is not economically rigorous.
Here’s why.

A shutdown temporarily reduces the government spending portion of GDP. But government consumption and investment make up roughly 15–17% of total GDP — and only a fraction of that is actually halted during a partial shutdown.
Even during the 35-day shutdown in 2018–2019, the Congressional Budget Office estimated the drag on quarterly growth at about 0.2–0.4 percentage points — not 1.5.

To move GDP from 3% to 1.5%, you would need a much broader slowdown: weaker consumer spending, reduced business investment, inventory pullbacks, or credit tightening. Those forces are large enough to shift growth meaningfully. A brief administrative pause is not.

A shutdown can create a modest, temporary dent. It does not cut economic growth in half.
