Africa’s richest industrialist, Aliko Dangote, is weighing a multi-exchange listing of his $20 billion oil refinery in a move that could reshape Africa’s capital markets.

The plan was disclosed by Frank Mwiti, chief executive of the Nairobi Securities Exchange, following a meeting in Lagos involving Dangote and leaders of several African stock exchanges.

The proposal would see the refinery, owned by Dangote Industries Limited, listed across multiple African bourses to attract a wider investor base and deepen market integration.

Dangote had earlier announced plans to list a 10 percent stake on the Nigerian Exchange Group.
