Are Germans wasting their savings abroad?

Abstract:

Germany is running a current account surplus of about 8% of GDP, which means that about one-third of all German savings (equal to 24% of GDP) has to be invested abroad every year. It has become by now almost a cliché that these huge excess savings are being wasted abroad. But this is a popular misconception based on the divergence between the available data on the (cumulated) current account balance (cCAB) of Germany and its net international investment position (NIIP).

A closer look at the data actually suggests that the NIIP is probably not measured correctly and that the observed returns on German investment abroad have remained above most domestic returns.
