What Ivan Glasenberg and co took years to attempt, the London market seems to have achieved in less than a week. Executives at Glencore have spent much of the past two decades building interests in mines, wells and ports, aiming to make the Swiss group less of a commodities trader and more of a fully-fledged miner.

Its correlation with the Reuters-Jefferies commodities index is just over half as strong.
