Central Bank

Unlike a commercial bank, a central bank does not compete for customer deposits or make consumer loans. It sits above the banking system as the sole issuer of a nation's fiat currency, the entity commercial banks turn to when they need liquidity, and the body tasked with keeping prices and the financial system stable.

A central bank's main lever is monetary policy. By raising or lowering its benchmark interest rate, adjusting bank reserve requirements, or buying and selling government securities (open market operations), it influences how much it costs to borrow and how fast money circulates through the economy. In a crisis it can act as "lender of last resort," extending credit to banks facing a liquidity crunch to prevent a wider collapse, as seen repeatedly since 2008. Most major central banks, including the Federal Reserve and the European Central Bank, operate with formal independence from day-to-day politics, though their leadership is still appointed by elected governments.

Crypto's origins are tied directly to skepticism of this system. Bitcoin's 2009 genesis block embedded a headline about bank bailouts, and its fixed 21 million supply was explicitly designed to resist the kind of monetary expansion central banks routinely use to manage economies. Many holders view Bitcoin and similar assets as a hedge against currency debasement and central-bank overreach.

Rather than ceding ground, central banks are now exploring their own digital money. A Central Bank Digital Currency would be issued and backed directly by the central bank, digitizing sovereign money rather than replacing it with a decentralized alternative, and remains an active but contested policy debate in most major economies.
