BEIJING: Chinese steel rebar and hot rolled coils futures surged over 6% on Tuesday, as production curb worries and peak season demand overshadowed a fee adjustment by exchanges.

The state planner had urged local governments to complete “self-inspection” for their steel projects and full-year output cut plan by mid-May, before it conducted on-site checks in June and July.

The announcement, seen as a curtain raiser for more crude steel production curbs, came as China’s factory gate prices expanded at the fastest pace in more than three years.
