How central banks manipulate interest rates and the money supply
Explore the mechanics of monetary policy through this walkthrough of the Federal Reserve's toolkit. This video examines how central banks influence the federal funds rate and the fundamental differences between the reserve regimes used before and after 2008.
Monetary policy involves measures used by governments to influence economic activity by manipulating money supplies, credit, and interest rates. The primary goal is often to stabilize prices, maintain full employment, and encourage economic growth. To achieve this, central banks like the Federal Reserve use several key instruments.
The most significant tool is open-market operations, where the Fed buys or sells government securities to affect interest rates. Buying securities increases bank reserves and lending capacity, which can lower yields. Other tools include the discount rate—the rate at which the Fed lends to commercial banks—and reserve requirements, which dictate the percentage of deposits banks must hold. While the reserve requirement acts as a brake on lending, it is rarely used because it is considered a blunt instrument.
