This document discusses the objectives and transmission mechanisms of monetary policy. It notes that central banks typically aim for price stability through interventions in financial markets to influence interest rates and liquidity. Monetary policy impacts the real economy through interest rate channels, as policy actions influence short-term rates and ultimately long-term rates that impact consumption, investment, and aggregate demand. Central banks can conduct open market operations, adjust reserve requirements, and set bank rates to expand or contract the money supply and thereby influence short-term interest rates in financial markets.
