The dollar slipped for a second straight session on Friday as recent economic data and a drop in oil prices cooled expectations for Federal Reserve rate hikes, though the yen remained in territory primed for intervention. The dollar index fell 0.39% to 101.11, on track for its biggest drop since June 11, while the euro rose 0.43% to $1.1418. U.S. crude fell 3.81% to $69.18 a barrel and Brent dropped 4.17% to $72.12 per barrel, with both on track for weekly declines of nearly 10%. Against the yen, the dollar weakened 0.12% to 161.59, and crossing 161.96 would take the Japanese currency to its weakest level since 1986. Despite the recent declines, the greenback was still up for the week and on pace for its strongest monthly percentage gain since March after hitting a 13-month high earlier in the week.
