Rating agency Moody's Investor Services has launched a new real-time raw data on the performance of asset backed and residential mortgage backed securities in a bid to improve transparency and boost investor confidence in these complex structured products at the heart of the credit crisis.

This new data feed is the latest attempt by the rating agency as it tries to reinstall investor confidence in its own services and the wider ABS market. Last week, Moody's launched a service providing European investors with an "early warning system" allowing them to detect risks and track the performance trends of ABS and RMBS in the wake of severe criticism of the ratings industry for failing to flag the advancing sub-prime mortgage crisis.
