Central Bank

A central bank is a national financial institution that manages a country’s currency and monetary system. It typically issues fiat money, influences interest rates, and works to maintain economic stability by targeting goals such as inflation control and a resilient banking sector.

In most modern economies, the central bank sits at the core of monetary policy. By adjusting policy rates and managing liquidity in the financial system, it affects borrowing costs, savings returns, and overall credit conditions. Central banks also support financial stability by supervising or setting rules for commercial banks, operating payment systems, and acting as a lender of last resort during periods of stress. In practice, this means the central bank can expand or contract the money supply, directly shaping how much money circulates and how expensive it is to access.

Cryptocurrencies such as Bitcoin were designed to operate without a central authority. Their supply rules are enforced by software and network consensus, not by a central bank, and they are generally not liabilities of any government institution. This distinction is a key reason crypto is often described as decentralized, no central bank guarantees its value or can unilaterally change its issuance.

At the same time, central banks matter to crypto because they regulate the broader financial rails that connect users to digital assets. Banking rules, payment settlement standards, and anti-money laundering requirements can influence how exchanges and custodians operate. Central banks are also exploring or issuing Central Bank Digital Currencies (CBDCs), which are digital forms of national currency, a direct liability of the central bank, designed to provide a government-backed alternative to privately issued digital assets.
