PR from Fitch: Fitch Places 87 RMBS Bonds Wrapped by MBIA on Rating Watch Negative

Fitch Ratings has placed 87 classes of residential mortgage-backed securities (RMBS) guaranteed by MBIA on Rating Watch Negative. Fitch placed MBIA's 'AAA' Insurer Financial Strength (IFS) on Rating Watch Negative following Fitch's announcement that it will be updating certain modeling assumptions in its ongoing analysis of the financial guaranty industry.

With the possibility that modeled losses for structured finance collateralized debt obligations (SF CDOs) may increase materially as a result of these updated projections, Fitch believes that loss projections will be most sensitive to loss given default assumptions used for SF CDOs that reference subprime RMBS collateral. Fitch will update the market upon conclusion of its analysis.

The ratings agencies are still tiptoeing towards the eventual downgrade.
