Basel committee still clueless chumps

They say... CDOs of ABS (so-called "resecuritisations") are more highly correlated with systematic risk than are traditional securitisations. Resecuritisations, therefore, warrant a higher capital charge. Fine so far. But then look what they do:(The new capital charges are in the grey hatched columns.) So the capital charge for a senior charge of a AAA-rated CDO-squared will be 1.6% of notional (20% x 8%). Anyone who thinks this is adequate was clearly taught in the Jimmy Cayne school of Structured Finance.

Update. I'll try to post more on the Basel 2 revisions (and in particular the trading book changes) in a few days. Meanwhile here is some good sense from Adair Turner, via the FT:
Lord Turner told a hearing of the Treasury select committee that tougher measures would include requiring banks to hold up to three times as much capital against their trading assets.

The entries are risk weights in percent, so the capital charge is the magic Basel 1 8% times the risk weight. Thus a A- rated tranche of a CDO squared would attract a risk weight of 60% of 8% of notional, i.e. 4.8%. Note that mezz of mezz was one of the nastiest things that you could buy in 2006-7...
