Here’s why…
European banks are (in addition to borrowing on a secured basis from those customers they usually lend to) also paying insurers and pension funds to take their illiquid bonds in exchange for better quality ones, in a desperate bid to secure much-needed cash from the ECB, which only provides cash against collateral. This may not be as safe a measure as it sounds. Below is a sensitivity analysis of Generali’s (a highly leveraged Italian insurer, subscribers see 
Exposure of European insurers to PIIGS) sovereign debt holdings.
As you can see, Generali is highly leveraged into PIIGS debt, with 400% of its tangible equity exposed. Despite such leveraged exposure, I calculate (off the cuff, not an in depth analysis) that it took a 10% hit to Tangible Equity. Now, that’s a lot, but one would assume that it would have been much worse. What saved it? Diversification into Geman bunds, whose yield went negative, thus throwing off a 14% return. Not bad for alleged AAA fixed income. But let’s face it, Germany lives in the same roach motel as the rest of the profligate EU, they just rent the penthouse suite! Remember, Germany is not in recession after a rip roaring bull run in its bonds, and I presume the recession should get much deeper since as a net exporter it has to faces its trading partners going broke. Below you see what happens if the bund returns were simply run along the historical trend line (with not extreme bullishness of the last year). 
Companies such as Generali would instantly lose a third of their tangible equity. This is quite conservative, since the profligate states bonds would probably collapse unless the spreads shrink, which is highly doubtful. Below you see what would happen if bunds were to take a 10% loss. 
That’s right, a 10% loss in bunds translates into a near 50% loss in tangible equity to this insurer, which would realistically be 60% plus as the rest of the EU portfolio will compress in solidarity. Combine this with the fact that insurers operating results are facing historically unprecedented stress (seeYou Can Rest Assured That The Insurance Industry Is In For Guaranteed Losses!) and it’s not hard to imagine marginal insurers seeing equity totally wiped out. The same situation is evident in banks and pension funds as well as real estate entities dependent on financing in the near to medium term – basically, the entire FIRE sector in both European and US markets (that’s right, don’t believe those who say the US banks have decoupled from Europe). 
The damage to banks will probably be worse due to the higher level of leverage in European institutions. This is saying a lot since Italy’s Generali is truly levered up the ASS! More… More on Reggie Middleton
