6/21/12, "Moody's downgrades 15 major banks," BBC
"The credit ratings agency Moody's has downgraded 15 banks and financial institutions.
UK banks downgraded include Royal Bank of Scotland, Barclays and HSBC.
In the US, Bank of America, Citigroup, Goldman Sachs and JP Morgan are among those marked down.
BBC business editor Robert Peston reported on Tuesday that the downgrades were coming and said that banks were concerned as it may make it harder for them to borrow money commercially.
"All of the banks affected by today's actions have significant exposure to the volatility and risk of outsized losses inherent to capital markets activities," Moody's global banking managing director Greg Bauer said in the agency's statement.
The other institutions that have been downgraded are Credit Suisse, UBS, BNP Paribas, Credit Agricole, Societe Generale, Deutsche Bank, Royal Bank of Canada and Morgan Stanley....
The BBC's Scotland business editor Douglas Fraser tweeted: "Cost of RBS downgrade by Moody's: having to post an estimated extra £9bn in collateral for its debts."
Of the banks downgraded, four were cut by one notch on Moody's ranking scale, 10 by two notches and one, Credit Suisse, by three notches.
"The biggest surprise is the three-notch downgrade of Credit Suisse, which no one was looking for," said Mark Grant, managing director of Southwest Securities."
