Via BusinessWire: “Fitch Ratings has downgraded JPMorgan Chase & Co.’s (JPM) Long-term Issuer Default Rating (IDR) to ‘A+’ from ‘AA-‘ and its Short-term IDR to ‘F1’ from ‘F1+’. Fitch has placed all parent and subsidiary long-term ratings on Rating Watch Negative. Fitch has also downgraded JPM’s viability rating (VR) to ‘a+’ from ‘aa-‘ and placed it on Rating Watch Negative. In addition, Fitch affirmed JPM’s ‘1’ support rating and ‘A’ support rating floor. A full list of rating actions follows at the end of this release. The rating actions follow JPM’s disclosure [May 10, 2012] of a $2 billion trading loss on its synthetic credit positions in its Chief Investment Office (CIO). The positions were intended to hedge JPM’s overall credit exposure, particularly during periods of credit stress. Fitch views the size of loss as manageable. That said, the magnitude of the loss and ongoing nature of these positions implies a lack of liquidity. It also raises questions regarding JPM’s risk appetite, risk management framework, practices and oversight; all key credit factors. Fitch believes the potential reputational risk and risk governance issues raised at JPM are no longer consistent with an ‘AA-‘ rating.”
