Federal Reserve System
In short
The central banking system of the United States that manages the nation's monetary policy and regulates financial institutions. It operates independently from direct political control to maintain economic stability.
In plain words
It is the main bank for the US government. It controls how much money is moving through the economy by changing interest rates. This helps keep prices steady and jobs available.
A simple example
If prices for food and fuel rise too fast, the Federal Reserve might raise interest rates. This makes borrowing money more expensive, which slows down spending and cools inflation.
Why it matters
Its decisions affect everything from mortgage rates to the value of the US dollar. Because the US dollar is used globally, its actions influence the entire world economy.
Easy to mix up
Do not confuse it with the US Treasury, which manages government spending and collects taxes.
