The Financial Stability Forum, a group of central bankers, has recommended to the G7 that they urgently take action to set up a clearing house for over the counter derivatives. They also call on accounting bodies to conclude work on valuing illiquid securities (so-called mark-to-market accounting) and urges the ratings agencies to offer a different ratings scale for structured credit products ( we suggest Toxic for the worst credits, Biohazard for medium-quality paper and top-rated securities would be ranked Putrid).
