Investors in Asia, meanwhile, took comments from erstwhile Federal Reserve hawk Christopher Waller as perhaps a signal of another era-shift, as he flagged that U.S. interest rates could be cut in the months ahead.
A rally in bonds and slide in the dollar that has run for weeks in the afterglow of a benign U.S. inflation report extended in Asia in the wake of Waller's remarks.
Two-year Treasury yields fell to a four-month low just below 4.70%. Ten-year Treasury yields hit a two-month low of 4.28%.
Interest rate futures price more than 100 basis points of cuts next year and a 40% chance they begin as soon a March.
The dollar's slide led to multi-month highs for the yen, euro, sterling and Swiss franc against the greenback and sent spot gold, in dollars, to its highest since May.
