I wouldn't be surprised is some economists and investors consulted psychics to try to gain an advantage. Each policy has one basic goal, impact the money supply. All of these policy actions work using the laws of supply and demand. The more money in circulation, the more spending there is and the higher inflation is. The less money there is in circulation, the less spending there is, inflation decreases.
Lets examine each of the policy actions and their possible results.
The Federal Reserve System has the power to set an amount, or percentage, of deposits that its member banks must keep in reserve at the Fed. If the fed raises its reserve requirements then banks have less money on hand and thus have less to lend. This lowers the amount of money in circulation and could have the impact of slowing the economy and inflation. Conversely if the fed lowers the reserve requirement , banks have more money on hand, more to lend and more money goes into circulation, thus increasing spending and possibly inflation. Changing The Discount Rate One of the most important and publicly watched Fed actions, the discount rate is interest rate that the Fed charges banks on money the banks borrow from the Fed.
