A senior Glencore Plc executive last year urged counterparts at Radiant World not to communicate by email, according to WhatsApp messages seen by Bloomberg News. "Say nothing on email," Peter Hill wrote in early April 2025. In other messages from 2023 to 2025, he highlighted Glencore's role as a key backer of Radiant World and suggested he was the ultimate decision maker for various aspects of its trading.

The messages raise questions about the depth of Glencore's involvement with Radiant World. Glencore was a key backer, but the relationship ended in acrimony with Glencore accusing Radiant World of fraud and Radiant World filing a $2 billion lawsuit against Glencore. Hill was suspended pending a review into Glencore's dealings with Radiant World.

Glencore declined to comment on the messages. Hill didn't respond to calls or messages. A Radiant World spokesperson didn't respond to a request for comment. The lawsuit was filed in Singapore this week. Glencore has said the "claims are meritless and we will contest them vigorously" and that Radiant World is suing it "for telling the truth about their fraud." Radiant World has denied wrongdoing. Glencore has taken a $480 million provision on its exposure to the group, which includes Sapphire Minmetals.
