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%.
This rate is set during the FOMC meetings by the regional banks and the Federal Reserve Board. The federal funds rate is the interest rate at which banks loan excess reserves to each other. While the Fed can't directly affect this rate, it effectively controls it through the way it buys and sells Treasuries to banks. There are 8 scheduled FOMC meetings during the course of each year.
