Glencore Plc took a provision of about $480 million on its exposure to Radiant World, the iron ore trader that is under pressure amid concerns it provided falsified documents to banks, according to people familiar with the matter. The provision effectively covers Glencore’s entire outstanding net exposure to Radiant World, the people said, asking not to be identified discussing private information. The move reflects growing scrutiny of commodity trade finance practices following allegations of document falsification by Radiant World.

Glencore’s chief executive officer, Gary Nagle, has not publicly commented on the provision. The development underscores risks in the global iron ore supply chain as banks and traders reassess counterparty credibility.
