"While the music is playing, you keep dancing," seems the only possible explanation for the fanatical demand for peripheral European bonds as everyone and their pet rabbit front-runs the ECB (or merely rushes to the 'yieldiest' thing given Draghi's implicit guarantee). At 3.1%, it beggars belief how 'risk' is mispriced in these sovereigns should any capital regulations ever mark sovereign debt as anything but riskless.
Remember what happened the last time Draghi did any bond-buying (the SMP) - we saw bonds sell off into the actual actions of the central bank... so it seems the market continues to trade on the promise (and yet hope it never comes true)...
Well that plan didn't work so well eh? It would appear that during the 2010 period spreads doubled from 100bps to 200bps and once again during the 2011 period, spreads almost doubled from 260bps to over 500bps in Spain.
