“…First of all, we note that the sovereign spread, that is, the di¤erence between the zerocoupon and the OIS 10-year rates, is on average positive also for Germany, contrary to the widespread belief that German yields can be used as proxies for risk-free rates. The dynamics of the German spread (Figure 1), as computed in this paper, are similar to those estimated by Wagenvoort and Zwart (2014), who propose a new factor analysis technique to extract the risk-free rate -a latent variable in their model -from a panel of euro area sovereign bond yields; their measure of the German sovereign spread, like ours, has been on average positive since the beginning of 2009.…”
