TREASURIES-US yields tumble as comments from Fed officials viewed as less hawkish, more balanced

Yields extended their fall after a fairly solid U.S. three-year note auction following a lackluster one in October. The slide in yields on the long end of the curve was much sharper than those on the short end in what is called a "bull flattener", a scenario which normally precedes a Fed rate cut, analysts said. A bull flattener, or in Tuesday's case a further inversion of the yield curve, typically reflects a decline in inflation expectations.
