U.S. Treasury yields slipped in choppy trading as U.S. data including the weak confidence numbers nudged up the possibility that the Fed could do another outsized rate cut at the November policy meeting.

U.S. rate futures have priced in a 62% chance of another rate cut of 50 bps at the November meeting, up from 54% on Monday, LSEG data showed. The more standard 25-bp easing showed a 38% probability on Tuesday.
