A gold standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of gold. The gold standard was the basis for the international monetary system from the 1870s to the early 1920s, and from the late 1920s to 1932[1][2] as well as from 1944 until 1971 when the United States unilaterally terminated convertibility of the US dollar to gold, effectively ending the Bretton Woods system.[3] Many states nonetheless hold substantial gold reserves.[4][5]
Historically, the silver standard and bimetallism have been more common than the gold standard.[6][7] The shift to an international monetary system based on a gold standard reflected accident, network externalities, and path dependence.[6] Great Britain accidentally adopted a de facto gold standard in 1717 when Isaac Newton, then-master of the Royal Mint, set the exchange rate of silver to gold too low, thus causing silver coins to go out of circulation.[8] As Great Britain became the world's leading financial and commercial power in the 19th century, other states increasingly adopted Britain's monetary system.[8]
The gold standard was largely abandoned during the Great Depression before being re-instated in a limited form as part of the post-World War II Bretton Woods system. The gold standard was abandoned due to its propensity for volatility, as well as the constraints it imposed on governments: by retaining a fixed exchange rate, governments were hamstrung in engaging in expansionary policies to, for example, reduce unemployment during economic recessions.[9][10]
According to a 2012 survey of 39 economists, the vast majority (92 percent) agreed that a return to the gold standard would not improve price-stability and employment outcomes,[11] and two-thirds of economic historians surveyed in the mid-1990s rejected the idea that the gold standard "was effective in stabilizing prices and moderating business-cycle fluctuations during the nineteenth century."[12] The consensus view among economists is that the gold standard helped prolong and deepen the Great Depression.[13][14] Historically, banking crises were more common during periods under the gold standard while currency crises were less common.[2] According to economist Michael D. Bordo, the gold standard has three benefits that made its use popular during certain historical periods: "its record as a stable nominal anchor; its automaticity; and its role as a credible commitment mechanism."[15] The gold standard is supported by many followers of the Austrian School, free-market libertarians, and some supply-siders.[16]
