Slowly even those staunchest critics of reality, namely undercapitalized and insolvent French banks, are coming to grips with the truth that they are going to see massive losses on their tens of billions of French debt exposure. The FT reports that the French stock market regulator has told French banks to apply realistic assumptions to their Greek debt haircuts. Because through today, French banks only used the 21% agreed upon haircut at the July 21 (and even that number is likely greatly overstated). So where are Greek bonds trading now? Oh about 30 cents on the dollar (70% haircut) , which means at the end of the day French banks will see about three time more losses on Greek holdings than provisioned. And the market, which is not all that stupid, knows this and has been punishing French banks. This is precisely what regulators are trying to avoid. The problem, as is well known courtesy of daily fruitless discussions between Sarkozy and Merkel, is that "French banks have more cross-border exposure to Greece than any other country, mainly through subsidiaries owned by Crédit Agricole and Société Générale. BNP Paribas holds the most Greek sovereign bonds among private sector investors, with €4bn of exposure...French banks argued that limiting themselves to 21 per cent was justified because trading in Greek government debt was so subdued, making market prices unreliable." Uh, what? Those billions in Greek bond volumes, where the 1 year yields 184% in dozens of daily trades, are "subdued" and "unreliable?" Why not just buy the bonds then and take advantage of the illiquid arb then? What's that? Crickets? Oh ok. In the meantime, what is certain is that after the ECB, France is the country most exposed to a Greek admission of reality (even truncated, assuming a 60% haircut which is still generous). Which of course confirms, once again, our thesis that the only source of EURUSD stability in the past two weeks have been French banks liquidating assets, and using the feedback loop of rising asset prices from FX EUR repatriation to sell even more to a willing market.
