The dollar posted moderate losses against the euro and yen on Tuesday as figures showing a surprise drop in U.S. retail sales in June dented optimism about U.S. economic growth and clouded prospects for a September rate hike by the Federal Reserve.
U.S. retail sales slipped 0.3 percent last month, the weakest reading since February, as consumers cut back on purchases of automobiles and other goods, according to a Commerce Department report. Excluding automobiles, gasoline, building materials and food services, core retail sales dipped 0.1 percent following a 0.7 percent gain in May.
Economists polled by Reuters had forecast retail sales rising 0.2 percent. Core retail sales had been expected to increase 0.4 percent.
Coming after a disappointing employment report for June and a sharp drop in small business confidence, the weak retail sales data suggested the U.S. economy may have lost some momentum at the end of the second quarter after struggling in early 2015.
Separately, the Commerce Department said U.S. business inventories rose modestly in May, suggesting restocking will probably not contribute to economic growth in the second quarter.
The euro, which fell 1.5 percent against the dollar on Monday in the wake of Greece's deal with creditors, was up 0.04 percent at $1.1007.
The dollar was last off 0.06 percent at 123.34 yen, dropping as low as 122.93. It earlier hit a 12-day high of 123.74 yen as the Japanese currency lost its safe-haven appeal with the worst-case scenario of Greece exiting the euro seemingly averted.
Sterling jumped to a one-week high of $1.5630 after Bank of England Governor Mark Carney said the time for a first UK rate hike since the financial crisis was getting closer. It was last at $1.5625, up 0.88 percent.
