The most consequential economic decisions in modern democracies are made by people who never face voters. Central bankers set interest rates, purchase trillions in assets, and effectively determine whether millions of people can afford mortgages, whether businesses can access credit, and whether governments can finance their deficits. This is not a bug in the system; it is the system, and understanding how it came to be reveals much about the strange architecture of contemporary power.
The independence of central banks from elected governments is treated as economic scripture, a principle so fundamental that questioning it marks one as either naive or dangerous. But this orthodoxy is remarkably recent. For most of the twentieth century, finance ministries directed monetary policy. The Bank of England was not operationally independent until 1997. The idea that unelected officials should control the money supply free from political interference only became consensus after the stagflation crises of the 1970s, when politicians were blamed for printing money to win elections.
The mechanics of unaccountable power
Central bank independence rests on a simple theory: politicians cannot be trusted with the printing press. Give them control, and they will inflate away debt, juice the economy before elections, and sacrifice long-term stability for short-term popularity. Better to delegate monetary policy to sober technocrats who can make unpopular decisions without fear of losing office.
The problem is that this framework assumes monetary policy is merely technical, a matter of adjusting dials according to economic models. In practice, every interest rate decision redistributes wealth. Low rates punish savers and reward borrowers. High rates crush indebted households while protecting those with capital. Quantitative easing inflates asset prices, enriching property owners and stockholders while doing little for wage earners. These are profoundly political choices dressed in the language of inflation targeting.
Mission creep and the expanding mandate
The financial crisis of 2008 transformed central banks from referees into players. When credit markets froze, the Federal Reserve, European Central Bank, and Bank of England became lenders of last resort not just to banks but to entire economies. They purchased government bonds, corporate debt, and in some cases equities. Their balance sheets ballooned from hundreds of billions to trillions. During the pandemic, this interventionism accelerated further, with central banks effectively financing government spending on a scale not seen since wartime.
This expansion has continued into climate policy, financial inclusion, and even inequality. The ECB now incorporates climate risk into its monetary policy framework. The Fed faces pressure to consider racial equity in its decisions. Whether one welcomes or deplores these developments, they represent a dramatic expansion of central bank mandates far beyond price stability.
Our take
The honest defence of central bank independence is not that it removes politics from money, but that it removes a particular kind of politics — the electoral kind — in favour of another kind: the politics of credentialed expertise and institutional continuity. This may be wise or unwise, but it should not be mistaken for neutrality. When a central banker raises rates and triggers a recession to control inflation, that is a political choice with winners and losers. The question democracies have largely avoided asking is whether such choices should remain permanently outsourced to officials who answer to no one but themselves.
