this rate indicate to the Fed the
Rate
amount of excess reserves in the Money
banking system.

Money Demand consists of two parts: Asset demand (liquidity
theory)- how much money the public wants to hold as a financial
asset for spending purposes; this is determined by interest rates and
moves demand along the curve. High interest rates discourage asset
demand (we prefer to save not spend).

Transaction demand- how much money the public needs in order to buy
available goods and services; this is determined by Nominal GDP and causes
the curve to shift. Higher NGDP would shift the demand curve right.
Another factor would be alternative means of spending such as credit card
use. Higher use of credit cards would shift the curve down. Changes in
money demand changes the interest rate.
