At almost the same time as the deal for control of Bear Stearns was announced, the Federal Reserve said it approved a cut in its lending rate to banks to 3.25 percent from 3.50 percent and created another lending facility for big investment banks. The central bank's official meeting is on Tuesday. Before the emergency move to lower the discount rate, which is the rate at which banks lend each other money, the Fed was widely expected to again cut its headline rate by as much as a full point to 2 percent.
