Under pressure by Massachusetts prosecutors, Bank of America Corp. said Wednesday it would reduce mortgage-loan balances as much as 30% for thousands of troubled borrowers, in what could presage a wider government effort to encourage banks to offer debt reduction to ease the mortgage crisis.

The plan is one of the boldest moves yet to address the plight of millions of U.S. homeowners who are "under water," owing more on their homes than they're worth. It could make it easier for the Obama administration to move in a similar direction with its existing loan-modification program, although senior government officials and many bankers remain very wary of offering to cut loan balances as the main way of helping distressed borrowers.
