According to an article on FT.com on 7 August 2018, “The European Investment Bank has agreed to start talks to become independently supervised by the European Central Bank after EU governments demanded sweeping governance changes at the lender after Brexit.” 

The 7 EU members states making these demands include Denmark, Sweden and the Netherlands and they are insisting that the EIB look to its “internal systems and introduce new supervision as a condition of governments putting more capital into the bank after the UK’s departure…”  

At this point the UK provides €39 billion to the EIB’s capital base.
