That is not the mandate of the EIB and has never been. From their website: “The European Investment Bank is the lending arm of the European Union.”
From the first paragraph on Wikipedia: “As a ‘policy-driven bank’ whose shareholders are the member states of the EU, the EIB uses its financing operations to bring about European integration and social cohesion. It should not be confused with the European Central Bank.”
About their mission: “ As the ‘Bank of the European Union’. the EIB's mission is to make a difference to the future of Europe and its partners by supporting sound investments which further EU policy goals.”

So this is exactly the kind of thing they do.
