WW1 disrupted the normal patterns of international finance. The gold standard, which prior to 1914 had been the basis of international finance, collapsed. After 1918, the world's financial markets struggled to return to normal. For some, this meant returning to the gold standard that had provided stability before the war. This was a time when exchange rates for currencies were fixed against the price of gold and therefore against each other. In April 1925, Britain went back on the gold standard. This was done at a time when the price of gold was high, which made British exports expensive.
