Central Bankers Alarmed by Washington's Growing Interference

European central bankers are departing the U.S. state of Wyoming and a key annual gathering after expressing concern that long-standing norms in global cooperation may be changing.

The central bankers, who were attending the Kansas City Fed's annual Jackson Hole Economic Symposium, said they are worried about the testy relationship between Washington and European institutions.

According to sources familiar with the discussions, Federal Reserve policymakers tried to ease concerns by promising to honor all of their commitments. However, they could not guarantee against sudden policy shifts by U.S. President Donald Trump, who has shown willingness to go to extraordinary lengths to get his will across.

The central bankers are particularly concerned about recent U.S. Treasury interventions, including the sale of euros for Japanese yen and debt buybacks. These actions foreshadow more intervention and breaks with norms, the officials said.
