The federal banking agencies have recently proposed guidance that would focus examiners' attention on those loans that are particularly vulnerable to adverse market conditions--that is, loans dependent primarily on the sale, lease, or refinancing of commercial property as the source of repayment. I emphasize that, in proposing this guidance, supervisors are not aiming to discourage banks from making sound loans in commercial real estate or in any other loan category. Rather, we are affirming the need for each bank to recognize the risks arising from concentration and to have in place appropriate risk-management practices and capital levels.
