An export credit agency or investment insurance agency is a private or quasi-governmental institution that acts as an intermediary between national governments and exporters to issue export insurance solutions, guarantees for financing. The financing can take the form of credits or credit insurance and guarantees or both, depending on the mandate the ECA has been given by its government. ECAs can also offer credit or cover on their own account. This does not differ from normal banking activities. Some agencies are government-sponsored, others private, and others a combination of the two.
