What Is It?
Central banks are government institutions that manage monetary policy, issue currency, and oversee banking systems. Major central banks include the Federal Reserve (U.S.), ECB (Europe), BOJ (Japan), and PBOC (China).
Origin
Central banking evolved from private banknote issuance to government monopolies. The Bank of England (1694) and Federal Reserve (1913) pioneered modern functions. The post-WWII Bretton Woods system institutionalized central bank cooperation.
Why It Matters
Central banks influence interest rates, credit availability, and currency values. Their policy decisions drive asset prices, economic growth, and inflation. Independence from political pressure is crucial for credible inflation targeting.
Intermediate Level
Market Mechanics
Tools include: policy rate setting, open market operations, reserve requirements, QE/QT, and forward guidance. Inflation targeting (2%) dominates developed economies. Dual mandates (price stability + employment) apply to the Fed. Unconventional tools emerged post-2008.
How It Behaves
Central banks cut rates and ease during weakness; hike and tighten during overheating. Communication affects expectations. Independence enables credible commitment. Global coordination occurs during crises. Unconventional policies have uncertain exit paths.
