Moody’s, the credit rating agency, has created a political storm in Athens by downgrading Greece’s government bonds by a further three notches. At B1 (down from Ba1), Greek bonds now “lack the characteristics of a desirable investment,” in Moody’s terminology.
But they are still acceptable for use as collateral in European Central Bank liquidity operations. Last May, the ECB suspended the minimum credit rating requirement for Greek debt – on the grounds that it had confidence in the country’s economic rescue plans, whatever the credit rating agencies thought. In other words, Greek banks could continue to obtain unlimited liquidity from the ECB, using their government bonds as collateral.
