According to CreditSights Inc analyst Baylor Lancaster, the most vulnerable financial institutions include Bank of America Corp, Citigroup Inc and Morgan Stanley. European banks are also expected to be on high alert, after S&P downgraded its scores for banking industries across numerous eurozone nations on November 9.

The latest update is said to be part of a major overhaul by S&P of its credit scoring system, after the agency was stung by criticism over its apparent role in the lead-up to the 2008 financial crisis.
Back then, all of the 3 major credit rating agencies had been accused of giving overly positive ratings for mortgage-backed securities and financial institutions, which eventually led to the housing bubble burst.

The push by S&P to upgrade its methods is also seen as a response to the decision by its parent company, McGraw-Hill Cos Inc, to divide itself into two separately listed companies.
Although S&P is said to have already started preparing companies and markets over its imminent changes, analysts believe that some banks could be in for a surprise once the updates are complete.
Earlier this month the agency published its final criteria for its update and said it expects 60 percent of all bank ratings to stay as they are, while 20 percent will go up by one grade, with 15 percent expected to fall by one grade and a further 5 percent to drop by two or more grades.
The world’s 30 largest banks though could be in store for as many of them are based in Western economies that have been heavily affected by the ongoing financial crisis.
