Human history has been shaped by the pursuit of valuable resources through trade, treaties, colonisation, and conflict. Today, nations compete economically, leveraging the strength of their currencies. Currency emerged centuries ago as a replacement for barter systems, initially as "commodity money" with intrinsic value tied to precious metals. The evolution towards "representative money" reflected practicality over intrinsic worth, backed by its ability to trade for goods. Today, a nation's economic power is symbolised by the strength of its currency in global trade. This guide looks at some of the strongest currencies in the world measured against the benchmark of the United States dollar as the standard currency.
