Fitch released a report today saying “ohmygod banks Europe” and the market went down and maybe there’s a causal link, whatever.
The report mostly takes notice of US banks’ European exposures in general, and the mystery of net versus gross derivatives exposure in particular, in which one asks “if Bank A sells CDS on $100bn of Italian debt to Bank B, and buys CDS on $100bn of Italian debt from Bank C, then when things go pear-shaped is it on the hook for zero (because it has no ‘net exposure’) or $100bn (because Bank C goes belly-up) or somewhere in between (because of collateral, sub-1 correlations, etc.)?”
It’s an important question: net exposures are manageable, gross exposures are terrifying, and there are legitimate questions about whether in a stress case the netting could break down. Various people who are smarter than me have tried to triangulate around parts of the answer using public data.
I don’t know the answer and doubt I’ll find out, though my gut is that netting should kind of sort of mostly work (I find Graph 5B of this, and the definition of “bilateral netting,” oddly comforting). What troubles me today, though, is that Fitch has no clearer answer than I do. Read more »
