Fed Chair Jerome Powell:

Policy changes continue to evolve, and their effects on the economy remain uncertain. The effects of tariffs will depend, among other things, on their ultimate level. Expectations of that level, and thus of the related economic effects, reached a peak in April and have since declined. Even so, increases in tariffs this year are likely to push up prices and weigh on economic activity.

 

The effects on inflation could be short lived—reflecting a one-time shift in the price level. It is also possible that the inflationary effects could instead be more persistent. Avoiding that outcome will depend on the size of the tariff effects, on how long it takes for them to pass through fully into prices, and, ultimately, on keeping longer-term inflation expectations well anchored.
