This Wall Street Journal editorial calls for more transparency in disclosing bad debt problems at Spanish and other European banks. It faults recent and upcoming stress tests of EU banks for not being stringent enough and taking into account adverse scenarios. While Spain's central bank says only 20 billion euros are needed to recapitalize the cajas savings banks, other estimates are much higher. Moody's country report says Spain could need upto 120 billion euros to recapitalize its banks. A big problem is European banks exposure in Spain which is over 700 billion euros as of September 2010- Spanish banks have high exposure in Portugal and German banks have high exposure to Spain.
