Credit ratings agency Moody’s has decided to downgrade 15 global banks and financial institutions.
In the US, Bank of America and Citigroup were among those marked down.
The UK banks downgraded were Royal Bank of Scotland, Barclays and HSBC. Lloyds also had its rating cut by Moody’s in a separate announcement.
The other institutions that have been downgraded are Goldman Sachs, Morgan Stanley, JP Morgan Chase, Credit Suisse, UBS, BNP Paribas, Credit Agricole, Societe Generale, Deutsche Bank and Royal Bank of Canada.
Moody’s added that it was putting some of the banks on a negative outlook, which is a warning that they could be downgraded again in the future.
Explaining this, it said governments around the world had shown a “clear intent” to reduce their support for banks going forward.
In Friday trading, shares in Royal Bank of Scotland (RBS) were up 0.8%, HSBC had gained 0.6%, and Barclays had risen 0.5%. Lloyds was 1.6% higher.
In France and Germany, Societe Generale was up 2.1%, while shares in Deutsche Bank were flat.
In a statement, RBS responded to its downgrade saying: “The group disagrees with Moody’s ratings change, which the group feels is backward-looking and does not give adequate credit for the substantial improvements the group has made to its balance sheet, funding and risk profile.”
RBS estimated that the downgrade could mean it would need to find an extra £9bn in collateral for its debts.
Lloyds said it believed that the change would have “limited impact on our funding costs and market capacity”.
In the US, Citigroup said it “strongly disagrees” with Moody’s decision.
Of the banks downgraded, four were cut by one notch on Moody’s ranking scale, including HSBC, Royal Bank of Scotland, and also Lloyds.
A further 10 banks had their rating reduced by two notches, including Barclays. Credit Suisse was lowered by three notches.
Moody’s separates the 15 banks into three groupings, relative to its assessment of their resilience to any global financial market turmoil.
It puts HSBC in its strongest “first group”, together with Royal Bank of Canada and JP Morgan.
Moody’s says these banks have “stronger buffers” than many of their peers, and “generally more stable businesses”.
Barclays is in its “second group” of banks which Moody’s says faces “sometimes adverse factors”. Other banks at this level are BNP Paribas and Goldman Sachs.
RBS is in the bottom “third group”, which comprises banks which “have been affected by problems in risk management, or have a history of high volatility”. Other banks in this grouping include Bank of America and Citigroup.
