Euronext Amsterdam is confident that derivatives trading will enable it to hold on to trading volumes in shares of oil group Royal Dutch Shell, despite the company's restructuring and its London listing.

Trading in Royal Dutch shares in the first five months of this year formed nearly a fifth of total turnover on Euronext's Amsterdam exchange. Shareholders last week approved the merger of the two public companies – Royal Dutch Petroleum, listed in the Netherlands, and Shell Transport and Trading, listed in the UK – that formed the Anglo-Dutch group a century ago.
