A gold standard fixes money's value to gold, and Isaac Newton helped start Britain on it

the gist

A gold standard is a monetary system in which the unit of money is defined as a fixed quantity of gold. It was the basis of the international monetary system from the 1870s to the early 1920s, and again in various forms until 1971, when the United States ended the dollar's convertibility into gold. Britain drifted onto it by accident in 1717, when Isaac Newton, as master of the Royal Mint, set the silver-to-gold exchange rate too low, pushing silver coins out of circulation. Britain's dominance then led other countries to copy its system.

how it works

Each unit of currency can be exchanged for a set amount of gold, so the money supply is limited by the gold available. When a country faces a recession, it cannot print money or cut rates freely without threatening that exchange rate. This rigidity is why economists see it as a constraint on governments.

so what

Because the currency was tied to gold, governments could not easily expand money supply or cut interest rates to fight recessions. Economists today largely reject a return to it, and a 2012 survey of 39 economists found 92 percent agreed it would not improve price stability and employment. Its legacy still shapes debates about central banks and monetary policy.

fun fact

Isaac Newton, famous for gravity, served as Master of the Royal Mint in Britain.
