Mercuria Energy has become Aegean Marine Petroleum Network's sole lender as part of a possible $1bn partnership following financial woes for the New York-listed bunker supplier.

Both companies in early July announced a memorandum of understanding where Mercuria will provide a $1bn trade finance facility to support Aegean's US and global credit facilities.

Mercuria will also provide a $30m loan for increased operational flexibility while Aegean will issue new shares equal to 30% of its common stock to Mercuria.
