While the US may have its "committee" decision to every problem in the world, Europe has the "summit meeting" which in the past would kiss and make everything better. No longer. As the following chart from Reuters indicates, annotating the relentless rise in Italian yields (which have about 100 bps in buffer from full out Eurozone collapse: if the 10 Year BTP hits 7.00% it's game over), the half life of the mere meeting in terms of favorable impact is now negligible and in fact, negative. Just like BOJ (and, some would add, Fed) interventions in the market now do more harm than good, so hollow Eurozone meetings without any actual resolution, simply make the Eurozone troubles that much more acute. Keep a close eye on the BTPs. They are already at 6% following last week's tumble first documented on Zero Hedge. If the price drops that much more, that will be it for the EMU experiment.
