Standard & Poor’s has cut the long-term credit ratings on Bank of America, Goldman Sachs and Citigroup to A- from A, along with a similar reduction to Morgan Stanley and Bank of America’s Merrill Lynch unit.

JP Morgan, which like the other banks operates in the wealth management space, was reduced one level to A from A+.

By contrast, the fortunes of Asia-based banks improved, as the rating agency upgraded Bank of China and China Construction Bank  to A from A- and maintained the A rating on Industrial & Commercial Bank of China.

S&P has also cut ratings on UBS and Barclays to A from A+, and HSBC to A+ from AA-.
