The dollar posted its second-steepest weekly decline versus other major currencies this year on Friday, while the yen strengthened sharply, and the dollar traded below 150 yen, as concerns grow about the weakening global economic outlook. Cooler-than-expected U.S. inflation data on Tuesday and Wednesday hastened market expectations for how soon the Federal Reserve will cut rates. Such a move would weaken a major dollar support and could come as early as next year’s first quarter.
The dollar index , which measures the greenback against six other major currencies, slid to lows last seen on Sept. 1, while the yield on benchmark 10-year Treasury notes fell to a two-month low of 4.379%. Data that showed U.S. single-family homebuilding increased marginally in October briefly supported the dollar, but with inflation the main market driver it remained lower on the day.
