http://www.cnbc.com/id/45482560Standard & Poor's reduced its credit ratings on 15 big banking companies, mostly in the Europe and United States, on Tuesday as the result of a sweeping overhaul of its ratings criteria.
JPMorgan Chase, Bank of America, Citigroup, Wells Fargo, Goldman Sachs Group, Morgan Stanley, Barclays, HSBC Holdings and UBS, were among the banks that had their ratings reduced by one notch each. A notch is one third of a letter rating.
S&P also left the ratings of 20 banks as they were and raised the ratings of two in announcing results from its new ratings criteria to 37 of the world's biggest banking companies. The agency also updated ratings for dozens of bank subsidiaries of the companies.
Although S&P began warning the markets more than a year ago that it was revising its ratings, the announcement comes at a time when the markets for bank debts are fragile.
