In a 32-bit program an address is a 32-bit value. In a 64-bit program an address is a 64-bit value (although only the low 48 bits are used). In a linear address space, the possible address space is 4GB. One note is that many hardware items are memory mapped to addresses.
However, this will not totally solve the Fedâs problem. Even when it was paying the banks 0.25% interest on reserves, the effective federal funds rate (the rate at which reserves at the Fed were actually being traded) was below 0.25%. This is why the Fed adopted a range for the federal funds rate of 0-0.25%.
The target federal funds rate, which is set by the Federal Reserve Board, serves as the basis for the prime rate. The federal funds rate is the interest rate commercial banks charge each other for overnight lending. Generally, the prime rate is about 3 percent higher than the federal funds rate. That means that when the Fed raises interest rates, the prime rate also goes up. Banks use the prime rate to set interest rates on numerous short-term loan products.
