A key Federal Reserve policymaker says interest rate cuts are not the appropriate response to trade concerns, revealing a split within the central bank over the proper way to respond to the White House’s spat with China.

Kansas City Fed President Esther George told Yahoo Finance that businesses are facing higher uncertainty over the ongoing U.S.-China trade war but expressed skepticism over the potency of Fed policy in addressing those concerns. George is a voting member of this year’s Federal Open Market Committee.

“Cutting interest rates is not likely to resolve that uncertainty,” George said on the sidelines of the Jackson Hole Symposium, an annual central banking conference hosted by the Kansas City Fed. “I take that into account when I think about how will our policy settings help in these situations. Or are there other things we should be taking into account?”

George notably voted against the Fed’s decision on July 31 to cut interest rates by 25 basis points, saying that the U.S. economic outlook was not dark enough to warrant easing policy. Minutes from that meeting, released on Wednesday, showed a wide spectrum of policy recommendations from Fed officials, ranging from 50 basis point cuts to no cuts at all.

Defending the decision to cut by 25 basis points, Fed Chairman Jerome Powell said July 31 that the cut was necessary to “insure against downside risks” from trade tensions. He noted that businesses have pulled back on capital spending amid the uncertainty.

Days after that rate cut, Trump threatened a new round of 10% tariffs of $300 billion of additional Chinese goods, originally scheduled for Sept. 1. After markets tanked on the news, Trump announced he would delay tariffs on some consumer goods.

Although George recognized that trade policy and a possible slowdown abroad remain risks, she said she would want to wait for the economy to see a materially weaker outlook before moving on rates.

“Uncertainty is a challenging one. It doesn't mean it can't affect the real economy and I think the more persistent that uncertainty is, that's what I’m watching for,” George said. She added that one example would be a negative spillover into consumer confidence.

The consumer, which represents about 70% of the economy, has been a bright spot of the U.S. picture so far. The Commerce Department reported last week that retail sales grew by an estimate-beating 0.7% in July, showing that tariffs have not severely damaged consumer activity so far. In July, consumer confidence as measured by The Conference Board, also rebounded.
