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.

Moody’s said it recognised, “the clear intent of governments around the world to reduce support for creditors”, but added that they had not yet put the frameworks in place that would allow them to let banks fail.

Some of the banks were put on negative outlook, which is a warning that they could be downgraded again later, on the basis that governments may eventually manage to withdraw their support.
