Central Bank
A central bank is the institution that manages monetary policy for a currency area, issuing the currency and steering interest rates, usually with price stability as its main goal.
What a central bank does
Examples include the US Federal Reserve (the Fed), the European Central Bank (ECB) for the euro area and the Swiss National Bank (SNB). Their typical tasks are issuing banknotes, setting the key policy interest rate, acting as the bank for commercial banks, keeping the payment system running and serving as lender of last resort when banks face a sudden shortage of cash.
Many central banks are legally independent of the government so that monetary decisions are not driven by short-term political goals. Their mandates differ: the ECB's primary objective is price stability, while the Fed has a dual mandate of stable prices and maximum employment.
The main tools
The most important lever is the policy rate, which influences what banks pay to borrow and therefore the rates on loans, mortgages and savings. Raising rates makes borrowing more expensive and tends to cool demand and inflation; cutting rates does the opposite.
When rates are already near zero, central banks may buy bonds on a large scale (quantitative easing) or later shrink those holdings (quantitative tightening). Communication itself is a tool: statements about future policy, often called forward guidance, can move markets before anything changes.
Why crypto markets care
Crypto trades in a global market where money flows toward or away from risk depending on financing conditions. Rate decisions, inflation data and central bank speeches are therefore watched closely, and prices can move sharply around scheduled announcements. The link is not mechanical: other news, positioning and crypto-specific events can outweigh any policy signal.
Central banks and digital money
Many central banks are researching or testing central bank digital currencies (CBDCs), a digital form of central bank money. A CBDC is a liability of the central bank and is not the same as a decentralized cryptocurrency.

Frequently asked questions
Who controls a central bank?
It depends on the country. Most are public institutions with a legal mandate and a degree of independence, and their leaders are appointed under rules set by law.
Do central banks print money?
They create central bank money, such as banknotes and bank reserves. Most money people use, however, consists of commercial bank deposits created when banks lend.
Why do crypto prices move on Fed decisions?
Changes in US interest rates affect global financing conditions and investors' appetite for risk, which spills over into crypto. The reaction varies and is often driven by surprises versus expectations.
