This book studies the so far unexplored operation of the international monetary system that prevailed before the emergence of the international gold standard in 1873. Conventional wisdom has it that the emergence of gold as a global anchor was both an inescapable and desirable evolution, given the exchange rate stability it provided and Britain's economic predominance. This study draws on a wealth of archival sources and abundant new statistical evidence (fully detailed in the appendix) to demonstrate that global exchange rate stability always prevailed before the making of the gold standard.
