On the economic front, U.S. consumer prices rebounded mildly in May, rising 0.1 percent on a seasonally adjusted basis after a 0.4-percent decline in April, the U.S. Labor Department said Tuesday.

Meanwhile, U.S. housing starts in May rebounded from a sharp plunge in April. Privately-owned housing starts in May jumped 6.8 percent to a seasonally adjusted annual rate of 914,000, the U.S. Commerce Department said. But building permits, a sign of future demand, fell 3.1 percent in May to a seasonally adjusted annual rate of 974,000, the department added.
