The brief

On the evening of October 6, 1979, eight weeks into his Fed chairmanship, Paul Volcker convened an emergency Saturday meeting of the Federal Open Market Committee. US inflation had reached 13%; the dollar was collapsing; previous tightening attempts had been timid. Volcker shifted operational targets from the federal funds rate to bank reserves, accepting whatever rate volatility resulted. Over the next twenty-six months the funds rate hit 20%, unemployment hit 10.8%, Volcker was burned in effigy on the steps of the Eccles Building, and inflation broke — 13.5% in 1980 to 3.2% by 1983. October 1979 is the conventional starting point of the modern central-banking era: independent technocratic authorities, inflation targeting as operational objective.

A modern central bank performs four core functions: monetary policy (setting short-term rates and, since 2008, the balance-sheet size), banking supervision (capital and liquidity requirements, intervening at failure), lender of last resort (emergency liquidity to solvent-but-illiquid institutions — Walter Bagehot's 1873 Lombard Street dictum: lend freely, at high rates, against good collateral), and payment-system infrastructure (Fedwire, TARGET2). The monetary-policy toolkit evolved from pre-2008 open-market operations to a post-2008 regime built on interest on reserves, forward guidance, and quantitative easing — large-scale asset purchases invented by the Bank of Japan in 2001 and now standard. The inflation-targeting framework that organized the post-Volcker era began with the Reserve Bank of New Zealand in 1990 and spread through the Bank of England, Canada, Sweden, Australia, and the European Central Bank (Maastricht-mandate price stability alone). The Federal Reserve's dual mandate (employment plus price stability) adopted a 2% inflation target through the Alan Greenspan–Ben Bernanke era and formally in January 2012. John Taylor's 1993 rule — funds rate = neutral rate + 1.5 × inflation gap + 0.5 × output gap — became the standard benchmark. Central-bank independence became the norm: the Bank of England in 1997, the Bank of Japan in 1998, the Reserve Bank of India in 2016. The 2008 GFC and 2020 COVID shock rewrote the playbook: rates to the zero lower bound, the Fed balance sheet from $0.9T to $8.9T at peak, then the 2022-23 tightening (Fed funds 0.25% → 5.50%, ECB −0.5% → 4%) that broke the 9.1% June 2022 inflation surge. Institutional credibility of inflation-targeting central banks survived the largest stress test in their history.

Why nowJerome Powell's Fed has been defined by COVID emergency response, the 2022-23 tightening cycle, and a soft-landing thesis playing out — disinflation without recession. Quantitative tightening is unwinding the pandemic-era balance sheet at ~$60B/month. US Treasury debt service hit $1 trillion per year in fiscal 2024, surpassing defense spending — fiscal-monetary tension that will shape policy through the late 2020s. Central-bank independence is contested again: Turkey under Erdoğan, Argentina's dollarization push under Milei, and the question of how the next US administration engages with Fed independence. Central Bank Digital Currencies are in active development (China's e-CNY operational, ECB digital euro in preparation). Modern Monetary Theory (Stephanie Kelton) peaked in 2020 and receded after the 2022 inflation surge.
