With uncertainty swirling around potential tariff actions — particularly the scope and timing of April’s proposed measures — US importers have accelerated their orders to get ahead of possible disruptions. That pull-forward has distorted economic optics, amplifying trade’s contribution even as domestic demand has remained relatively stable.
Imports as a share of GDP rose sharply in Q1 to historic levels, suggesting that the drag on growth was more about timing than fundamentals. In the GDP accounting framework, imports are subtracted from total output because they represent spending on goods and services not produced domestically. When imports rise sharply without a corresponding increase in exports or domestic production, they create a negative contribution to GDP — even if underlying demand remains strong. Conversely, a decline in imports can mechanically boost GDP by reducing that drag, even if it’s driven by inventory normalization or weaker consumption. This makes trade flows a frequent source of noise in quarterly growth figures, often obscuring true economic activity.

That surge now appears to be reversing. The ISM Manufacturing Index’s imports component has slipped below Covid-era contraction territory, a signal that import activity is cooling as firms digest elevated inventory levels built earlier in the year.

This reversal is already feeding into real-time growth tracking. The Atlanta Fed’s GDPNow model projects a healthy rebound in Q2 GDP, with net exports swinging from a significant drag to a meaningful tailwind, with total GDP growth for Q2 expected to print near 4%. A front-loaded import spike subtracts from one quarter’s GDP, followed by an import pullback that boosts the next.

But beyond quarterly arithmetic, importers’ willingness to act preemptively introduces a latent cushion into the economy — inventory buffers and forward positioning that can absorb supply chain stress before it filters into consumer prices. In the near term, this could delay inflationary pass-through, lowering the urgency of a policy response.
While the underlying growth dynamic remains weaker than in 2024, the likely Q2 rebound should ease fears of an imminent recession. If tariff risk remains live or escalates, this pattern is likely to repeat: episodic hoarding, inventory payback, and supply chain volatility that blunts business confidence and weighs on capital formation. None of this suggests a hard landing. But it does imply that the expansion will remain vulnerable to exogenous shocks and structurally constrained by policy uncertainty.
In short, the growth trend remains positive, but fragile. Import behavior in Q1 wasn’t a signal of strength or weakness — it was a hedge. And the more firms feel the need to hedge against policy, the harder it becomes to sustain real momentum.
