NEWS WIRE DISCOUNT RATES Fed Cuts Key Interest Rate Eighth Time in Year Washington, DCAlarmed by the rapidly weakening economy, the Federal Reserve cut a key interest rate again yesterday. This is the eighth time this year the Fed had cut the discount rate, dropping it from 4.75 percent at the beginning of the year to a mere 0.50 percent now. The discount rate is the rate the Fed charges for loans it makes to private banks. By dropping the rate, the Fed is hoping banks will borrow more money, then use that money to make new loans to businesses and consumers. What has spooked the Fed is that GDP is falling at the fastest rate in 50 years. The Fed is hoping that record low interest rates will prompt more Spending, preventing a protracted recession.
