Homework :

Reuters Breakingviews has done a stress test of its own on eurozone banks with the same official data the EU stress test used. It allows u to view the results according to the level of hair cut and tier 1 capital ratio u think suitable, hair cuts provided are marked to market 10/12/2011 for 5 years bonds.

Example :

Capital tier 1 ratio at 9%, Greece  hair cut at 50%, other sovereigns marked to market as of 10/12 leaves France’s banks with a capital shortfall of 40.5 billions. BPCE shortfall 12.3 billions, SocGen 12.3, BNP 12.1, CA 3.6 (Not included Greece Subs).

Loved it, great tool for simulations. Note that the impact on state debt is assuming the taxpayer picks the entire bill.

Have fun and enjoy.
