May 17 (Reuters) – Shell International Trading and Shipping Company Ltd this month resumed trading in coal derivatives more than a decade after parent Royal Dutch Shell exited the coal business and sold its mines, sources close to the company said.
Shell declined to comment.
Shell actively trades power, gas and carbon so the move back into coal fills a gap in the energy markets it trades and will enable more effective spread-trading and hedging, they said.
