The Federal Reserve is not likely to soon repeat a probe of capital buffers at the nation’s biggest banks, but the model of the across-the-board exam will be used again, Fed Chairman Ben Bernanke said Friday.

"I don’t anticipate repeating the stress tests in the near term, but many of the lessons, particularly looking at the system as a whole, trying to identify system-wide exposures, system-wide practices that pose risks, will be part of our basic toolkit going forward,” he said after a speech at a conference organized by the Boston Fed.
