So says German paper Handelsblatt in an article published today and just out on Bloomberg

BOS have declined to comment

No further detail at present

Update:

Handelsblatt claim that the BOS repeatedly stretched ECB rules for what securities that banks can use as collateral for ECB funds

  • some securities are accepted that don't meet the ECB's criteria
  • other bonds meet criteria but are given lower discount then ECB rules demand
  • Banco de Sabadell is one example of a bank that had securities accepted that shouldn't have been

Still no response from the BOS but this needs some answer/ explanation
