Fed Chair Jerome H. Powell on Friday said it is now becoming clear that the tariff increases will be significantly larger than expected.

“The same is likely to be true of the economic effects, which will include higher inflation and slower growth. We have stressed that it will be very difficult to assess the likely economic effects of higher tariffs until there is greater certainty about the details, such as what will be tariffed, at what level and for what duration, and the extent of retaliation from our trading partners,” Powell, chair of the board of governors of the US Federal Reserve System, underlined.

The size and duration of these effects remain uncertain. “While tariffs are highly likely to generate at least a temporary rise in inflation, it is also possible that the effects could be more persistent. Avoiding that outcome would depend on keeping longer-term inflation expectations well anchored, on the size of the effects, and on how long it takes for them to pass through fully to prices. Our obligation is to keep longer-term inflation expectations well anchored and to make certain that a one-time increase in the price level does not become an ongoing inflation problem,” he added.

“We will continue to carefully monitor the incoming data, the evolving outlook, and the balance of risks. We are well positioned to wait for greater clarity before considering any adjustments to our policy stance. It is too soon to say what will be the appropriate path for monetary policy.
