NEW YORK (AP) - Moody's Investors Service lowered the credit ratings of 15 the world's largest banks late Thursday, including Bank of America, JPMorgan Chase and Goldman Sachs, saying their long-term prospects for profitability and growth are shrinking.
The ratings agency said it was especially concerned about banks with significant financial markets businesses because those markets have become so volatile. Some of the largest European banks were also downgraded, including Barclays, Deutsche Bank and HSBC.
The downgrades mean Moody's is more concerned about the ability of the banks to repay their debts. Moody's had said in February that it was considering downgrading the credit ratings of major banks in the U.S. and in Europe.
A downgrade usually means that it becomes more costly for banks to raise money by selling debt. Investors demand higher interest for riskier debt, which is what the downgrades represent. However, with interest rates already at rock-bottom levels, the downgrades may not affect the cost of funding for the banks that much.
The stock market has also priced in any negative impact from the ratings downgrades, according to Bert Ely, a banking consultant in the Washington, D.C. area.
In a sign that investors were taking the news in stride, stocks of major U.S. banks rose in after-hours electronic trading. Moody's made its announcement after regular stock trading had closed. Morgan Stanley rose the most, 3.3 percent, gaining 45 cents to $14.41. JPMorgan Chase rose 41 cents to $35.92 and Bank of America rose 12 cents to $7.94.
The downgrades come at a time of great uncertainty in the global economy. Europe's currency union is under threat from bad bank loans. The U.S. economy is slowing and the fast-growing emerging economies of India, Brazil and China are also cooling. Financial markets have also been volatile.
On Thursday the Dow Jones industrial average plunged 251 points, its second-worst loss of the year, as new reports indicating slower manufacturing in the U.S. and China made investors fearful that the global economy could be heading for another slump.
Moody's has been on a downgrading spree lately. In June Moody's downgraded Spain by three notches, after downgrading 16 Spanish lenders in May. It also cut the ratings on seven German and three Austrian lenders in June.
