The interest rate is a nominal rate.
Monetary policy targets the Federal Funds rate (the rate banks charge each other for over-night loans). Changes in this rate indicate to the Fed the amount of excess reserves in the 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.
