In order to address the unreliability and volatility of a currency system that was formerly reliant on banknotes produced by private banks, the Federal Reserve Act of 1913 established the Federal Reserve Bank. The United States economy surpassed that of the United Kingdom at the same moment, becoming the biggest in the world. However, because most transactions were conducted in British pounds, the U.K. continued to dominate global trade.
To stabilize currency exchange rates, the majority of developed nations tied their national currencies to gold. However, several nations discontinued their use of the gold standard when World War I started in 1914 in order to pay their military costs with paper money, devaluing their own currencies in the process. The third year of the war saw Britain borrow money for the first time, although adhering to the gold standard to keep its place as the dominant currency in the world.
When nations desired to purchase U.S. bonds denominated in dollars, the United States became their preferred lender. In 1931, Britain finally ended the gold standard, decimating the bank accounts of foreign traders that dealt in pounds. By that time, the dollar had overtaken the pound as the main global reserve currency.
The Bretton Woods Agreement made the U.S. dollar the recognized reserve currency of the world, backed by the greatest gold reserves on earth. Other nations amassed US dollar reserves as opposed to gold reserves. Countries started purchasing U.S. Treasury securities because they needed a place to put their dollars and thought it was a secure location to keep their money.
The United States oversupplied the market with paper money due to the demand for Treasury securities and the deficit spending required to pay for the Vietnam War and the domestic projects of the Great Society. The countries started converting their dollar reserves into gold as concerns over the stability of the currency grew.
As a result of President Richard Nixon's intervention to break the link between the dollar and gold due to the high demand for gold, today's floating exchange rates were created. The U.S. dollar has continued to be the world's reserve currency despite instances of stagflation, which is characterized as high inflation and high unemployment.
The dollar continues to be used as the global reserve currency. The International Monetary Fund estimates that central banks maintain around 59% of their reserves in U.S. dollars (IMF). The majority of the reserves are in the form of cash or US bonds like US treasuries. Foreign debt held in dollars is still increasing, with levels expected to reach $13.4 trillion by the middle of 2022.
The majority of people would assume that this makes the dollar the world's strongest currency. The dollar was recognized as the 10th strongest currency by CMC Markets despite its prominent position and dependence on international markets. The British pound and the euro were placed fifth and eighth on the website's list of strongest currencies, respectively, while the Kuwaiti dinar claimed the top spot.
