"That's the most important thing I'm worried about," Waller said on Saturday, adding that moving rates quickly up to the neutral level and into restrictive territory is necessary to slow demand and put a check on inflation.
That monetary tightening will likely drive unemployment, now at 3.6%, to between 4% and 4.25%, or possibly higher, Waller said, "but my goal is just to slow the economy." Rising worries that Fed rate hikes will cause a recession, he said, "are a bit overblown."
Waller also said there are limits to how fast the Fed can move: markets would have a "heart attack" if the central bank raised rates by a full percentage point in a single move.
