Shanghai rebar jumps nearly 3% on demand hopes, lean supply

Chinese rebar steel futures climbed almost 3% on Tuesday, gaining for a second straight day on tighter supply and expectations that demand in the world's top consumer would bounce back when production curbs are lifted after winter. Chinese steel mills, mainly across the country's north, have been ordered to curb output during winter as part of Beijing's campaign to limit air pollution. The curbs apply from this month through March.
