The Federal Reserve will consider whether new regulations could curtail lending practices that have contributed to a rise in mortgage delinquencies, Fed Chairman Ben Bernanke said in a letter released on Friday.

"With respect to the recent problems in the subprime mortgage market, the Board plans to consider how it might further use its rulemaking authority ... to address particular lending practices," Bernanke said in a May 18 letter to Senate Banking Committee Chairman Christopher Dodd, a Connecticut Democrat.
