When was the first reliable exchange rate between British pound and US dollar?
Could you elaborate on the origins of the first reliable exchange rate between the British pound and the US dollar? I'm curious to know when this benchmark was established and what factors influenced its determination. Was it during the early stages of globalization when trade between the two nations flourished? Or perhaps it emerged from the development of modern financial institutions? I'm also interested in understanding how the exchange rate has evolved over time and the significance it holds in today's global economy. Your insights would be greatly appreciated.
