Why the Dollar Became the Global Currency

Why the Dollar Became the Global Currency: A Historical and Geopolitical Tale

The story of the U.S. dollar’s rise as the global currency is as much about history and economics as it is about power and influence. Let’s journey through time to understand how the dollar came to dominate the world.

A World Before Currency

Thousands of years ago, there was no such thing as currency. People traded goods through the barter system. If you had tomatoes and needed rice, you’d exchange your tomatoes with someone who had rice. While this worked for small transactions, it became a problem for larger trades. Goods like tomatoes and rice would spoil over time, making long-term trading difficult.

To solve this, people began trading in durable goods like gold, silver, and copper. These metals didn’t spoil and could be stored for long periods. Lydia,(an Iron Age kingdom situated in the west of Asia Minor, in modern-day Turkey), was the first to mint coins from gold and silver, simplifying trade further. But even this system had its flaws. When people traveled long distances with heavy coins, they faced the risk of theft and the burden of transport.

The Birth of Paper Currency

As trade expanded, people found new solutions. In China, traders began depositing their gold with trusted businessmen who issued stamped and signed papers as proof. These papers could be taken to another city and exchanged for gold, making trade safer and easier. This system eventually evolved into paper currency.

Europe adopted this idea in the 13th century after Marco Polo visited China. Soon, paper currency became the standard across Europe. For instance, Britain’s Pound Sterling was backed by gold, with each pound representing a fixed amount of gold. This made trade reliable and secure.

The Gold Standard and Global Trade

By the 19th century, most countries operated under the gold standard. A country could only print as much currency as it had gold reserves. Nations that produced more goods and resources accumulated more gold, giving them economic power. During this time, Britain, with its vast resources and industrial might, became the world’s leading economy. The Pound Sterling was the dominant currency, accounting for 60% of global trade.

World Wars and the Dollar’s Rise

Everything changed with the First World War. Britain’s economy suffered heavily as it spent its gold reserves on the war. In contrast, the U.S. remained neutral for much of the war, selling weapons and supplies to other nations and amassing gold. By the war’s end, the U.S. had one of the largest gold reserves in the world.

The Second World War further shifted the balance. The U.S. again profited by supplying weapons and resources. When the war ended, European countries were in ruins, and their economies had collapsed. In 1944, representatives from 44 countries met at Bretton Woods in the U.S. to create a new global financial system. They decided to peg their currencies to the U.S. dollar, which in turn was backed by gold at a fixed rate of $35 per ounce. This made the dollar the world’s reserve currency.

Oil and the Petrodollar

After the war, oil became the backbone of the global economy. In 1945, the U.S. struck a deal with Saudi Arabia: in exchange for military protection and technological assistance, Saudi Arabia agreed to sell oil exclusively in dollars. This forced countries worldwide to hold dollars to buy oil, solidifying the dollar’s dominance.

The Nixon Shock

By the 1970s, the U.S. started printing more dollars than it had gold reserves, creating a problem. Other countries, noticing this, began exchanging their dollars for gold. Facing a potential economic collapse, President Nixon announced in 1971 that the dollar would no longer be convertible to gold. This move, known as the “Nixon Shock,” turned the dollar into a fiat currency, backed only by trust in the U.S. government.

Despite initial uncertainty, the petrodollar system ensured the dollar’s continued dominance. Oil-exporting countries like Saudi Arabia invested their dollar earnings back into the U.S., creating a cycle that kept the dollar strong.

Challenges to the Dollar

Over the years, some countries have tried to challenge the dollar’s supremacy. Iraq’s Saddam Hussein began selling oil in Euros, and Libya’s Muammar Gaddafi proposed a unified African currency. Both leaders faced severe pushback, leading to regime changes. Similarly, Iran’s attempt to trade oil in Euros was met with heavy U.S. sanctions.

Weaponizing the Dollar

The U.S. uses the dollar as a geopolitical tool. The SWIFT network, essential for international transactions, is influenced by the U.S. Excluding a country from SWIFT, as seen with Iran and Russia, can cripple its economy. Sanctions imposed by the U.S. also isolate nations economically, showcasing the dollar’s power beyond trade.

The Future: De-dollarization Efforts

In recent years, countries like China, Russia, and Brazil have sought alternatives to reduce their reliance on the dollar. Initiatives include trading in local currencies and proposing new systems like a shared BRICS currency. However, creating a viable alternative to the dollar remains a significant challenge.

Conclusion

The journey of the U.S. dollar from a national currency to a global powerhouse is a tale of strategy, circumstance, and influence. While challenges to its dominance exist, the dollar remains at the heart of global trade and finance, shaping the world’s economic landscape.
