U.S. retail sales unexpectedly increased in August, rising 0.7% from the previous month despite expectations of a 0.8% fall, while business sentiment survey by the Philadelphia Fed also showed a big improvement. read more "Yesterday"s data were pretty strong across the board," said Yujiro Goto, chief currency strategist at Nomura Securities. "The markets had been worried that consumption would be weak in August because of the Delta variant. But retail sales were surprisingly strong." The figures helped to curb cautious views on the U.S. economy sparked after tame consumer inflation reading and soft job growth data published earlier this month, helping to revive expectations for early Fed tapering.
