How much could trade policy uncertainty hurt the outlook?

If there’s one thing more damaging than tariffs themselves, it’s the sharp rise in trade policy uncertainty. Our latest assessment shows that sharp rise in trade policy uncertainty and broader global policy uncertainty is likely to significantly harm global growth, particularly business investment, with repercussions in the US, Europe and China.

There is extensive academic literature and evidence that elevated uncertainty with downside risks is bad for economic growth. The key point is that many major decisions for households and businesses are costly to reverse. For firms, this might include investment, hiring, R&D, and entering a new market, while for consumers, it might include house purchase and major durable goods. When uncertainty is high, there may be a strong incentive to defer such major decisions until the situation is clearer, especially if the scale of downside risks is large.

We developed four distinct scenarios for trade policy uncertainty (TPU), assessing their effects on private business investment in major economies. In all scenarios, investment is markedly weaker during this year from the recent rise in uncertainty.
