Consumer prices were level in February, the Labour Department reported, while the New York-based Conference Board's index of leading economic indicators rose 0.1 percent in February, the 11th straight monthly gain but down from 0.3 percent in January.

US President Barack Obama, meanwhile, signed an $18-billion jobs package that provides tax incentives for small businesses, amid an unemployment rate of 9.7 percent.
