Are Germans wasting their savings abroad? CEPS Commentary, 7 April 2016

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.

A sovereign wealth fund to lift Germany's curse of excess savings. CEPS Policy Brief No. 280, 28 August 2012

As an alternative to the present system of intermediation of the German savings surplus, this paper suggests that the risk-adjusted rate of return could be improved by creating a sovereign wealth fund for Germany (designated DESWF), which could invest excess German savings globally. Such a DESWF would offer German savers a secure vehicle paying a guaranteed positive minimum real interest rate, with a top-up when real investment returns allowed. The vehicle would invest the funds in a portfolio that is highly diversified by geography and asset classes. Positive real returns can be expected in the long run based on positive real global growth. Since, in this case, a significant amount of funds would flow outside the euro area, the euro would depreciate, which would help crisis countries presently struggling to revive growth through exports and to close their external deficits so as to recoup their international credit-worthiness. Target imbalances would gradually disappear and German claims abroad would move from nominal claims on the ECB to diversified real and nominal claims on various private and public foreign entities in a variety of asset classes.
