The Dollar¶
The dollar has evolved from a silver thaler minted in 16th-century Bohemia into the world's dominant reserve currency, accounting for over 80% of international transactions. This transformation -- spanning five centuries and multiple monetary regimes -- reflects changing economic conditions, technological developments, and geopolitical power shifts.
The Potato King and the Origin of the Dollar¶
In the northwest portion of the modern-day Czech Republic is a town named Jachymov, meaning "Saint Joachim's Valley" -- in German, Joachimsthal. When silver was discovered in the area in the 16th century, it became a mining community. Count Hieronymus Schlick of Bohemia, a prominent nobleman and mining magnate, invested heavily in new mining technologies and established the famous Joachimsthal mine. In 1518, Schlick minted the thaler -- a large silver coin with uniform weight and high silver content. The coin had all the makings of good money: portable, divisible, durable, and scarce. Its uniformity meant it was fungible, so it quickly gained broad acceptance.
Within a generation, the silver from these mines would be used to mint Reichsthalers, the official currency of the Holy Roman Empire for 300 years. The thaler became so widely used that it was adopted across Europe, and as acceptance normalized it became the coin of account for the whole Empire -- all goods and services were priced in thalers rather than weights of silver or gold. The word "dollar" derives from thaler, which evolved linguistically through common usage.
Before there was Satoshi Nakamoto and Bitcoin, there was Frederick the Great and the thaler. Frederick II of Prussia (1740-1786) reigned during the Seven Years' War (1754-1763), a global conflict spanning five continents. Like all wars, it left participant countries economically wounded. Governments resorted to the familiar solution: debase the currency.
Frederick's response was bold and progressive. His 1763 Mint Edict set fixed rates of depreciated wartime coins to pre-war coins, effectively reversing inflation's impact. He withdrew depreciated money from circulation and ordered the minting of new thalers at a specified ratio to silver. Currency speculators lost money, but hyperinflation was averted, saving 18th-century Europe from post-war economic collapse.
Frederick is also known as the Potato King. When Prussia's peasants starved during wartime, Frederick saw opportunity in the nutritious potato -- which the population despised as a garbage plant not mentioned in the Bible. He planted "Royal Potato Fields" outside Berlin with fencing, signage, and soldiers guarding them conspicuously. The secret was that Frederick had instructed his guards to not be too diligent -- to take frequent naps and accept bribes. Villagers successfully "stole" the royal potatoes for their own gardens, and the hated vegetable spread throughout Prussia. Frederick's reverse psychology is one of the earliest instances of wildly successful artificial scarcity.
The Early American Dollar¶
Constitutional Mandate: The U.S. Constitution specifically mandated gold and silver coin as the only acceptable form of currency states could use: "No State shall... coin Money... [or] make any Thing but gold and silver Coin a Tender in Payment of Debts" (Article 1, Section 10).
The Coinage Act of 1792: This Act established the United States Mint and adopted the dollar as the official U.S. currency, based on the Spanish dollar (itself based on the thaler). Section 19, the "Debasement Clause," made currency debasement punishable by death.
Continental Congress (1775): During the American Revolution, the Continental Congress issued paper money known as Continental currency to finance the war effort. Lacking gold or silver backing and subject to overprinting, the value declined rapidly, creating the phrase "not worth a Continental."
America: The Land of Financial Panics¶
The Crime of '73: The Coinage Act of 1873 eliminated the silver dollar as a unit of account and replaced it with the gold dollar, effectively ending the bimetallic standard. The silver-mining industry suffered, holders of gold benefited, and the Act was so hated it led to the creation of the Populist Party -- a coalition of farmers, laborers, and small business owners opposing the gold standard as a tool of the wealthy.
The Free Silver Movement: In response, the Sherman Silver Purchase Act of 1890 required the government to buy large amounts of silver monthly. But Gresham's Law played its role: with gold increasing relative to silver but both being legal tender, people spent silver and hoarded gold. Citizens paid taxes in silver while international creditors demanded gold. The Treasury accumulated silver while gold flowed out, contributing to bank failures and the Long Depression of 1893-1897.
Political Consequences: The economic distress radicalized citizens. Leon Czolgosz, who lost his job when mills closed during the 1893 crash, joined anarchist groups and in 1901 assassinated President William McKinley -- who had ironically campaigned on returning to the gold standard.
The Panic of 1907: Over-speculation led to the collapse of the Knickerbocker Trust Company. Its president, Charles Barney, killed himself three weeks later. Bank runs spread as depositors lost confidence. With no federal mechanisms to regulate banks or provide emergency liquidity, J.P. Morgan organized a consortium of bankers who pooled resources to buy troubled assets and prevent complete economic collapse. Out of the 1907 Panic, the Federal Reserve was born.
The Gold Standard Era¶
By 1900, the United States formally adopted the gold standard. Gold brought stability and growth, but the standard's limitations -- limited money supply and inflexibility during downturns -- became apparent during the Great Depression.
How the Dollar Replaced Gold¶
World War I: The war caused many countries to abandon the gold standard. There was simply not enough gold in their treasuries to pay for the conflict. Money was printed without gold backing. The result in most countries was rampant inflation: prices doubled in the U.S. and Britain, tripled in France, quadrupled in Italy, and Germany descended into catastrophic hyperinflation.
The U.S. did not suspend the gold standard during the war. Far from the battlefield, America entered late, provided a comparatively small military force, and did not suffer destruction of production facilities. The newly created Federal Reserve intervened in currency markets and sold bonds to offset inflationary gold imports. By 1927, many countries returned to the gold standard, but the United States had moved from net debtor to net creditor, tripling its gold reserves between 1915 and 1935. Fort Knox was built in 1935 to secure these unprecedented holdings.
Bretton Woods (1944): After World War II, the United States had the only functioning economy of meaningful size. At a conference of 44 countries in New Hampshire, the Bretton Woods system established the dollar as the world's reserve currency, fixed to gold at $35 per ounce. The Allies, devastated by war, had no choice but to accept. Only the Soviets refused -- a decision that would cost them their country 45 years later.
Under Bretton Woods, the United States controlled two-thirds of the world's gold, produced 80% of the world's food, controlled global seafaring chokepoints with its navy, and was creditor to nearly every war participant.
The Nixon Shock (1971)¶
The Bretton Woods system contained an inherent contradiction. The U.S. exported far more than it imported, requiring other countries to acquire dollars -- but the total dollars potentially exceeded gold reserves. Having a globally dominant currency meant the issuer needed enough gold to represent a vast and growing amount of international trade. This was impractical.
Additionally, the baby boom meant more people entering the workforce. A larger population needed to be paid and needed access to money domestically -- demand that could not be met with the dollar pegged to gold.
In 1971, Nixon announced the U.S. would no longer convert dollars into gold. Given the disastrous history of paper money, the decision seems perplexing. But it gave the government greater flexibility: the ability to print money for international trade and a growing population without gold reserve constraints.
The Petrodollar System (1974)¶
The 1973 Yom Kippur War led to an Arab oil embargo that caused a sharp increase in oil prices and a global energy crisis. To end the embargo and neutralize crude oil as an economic weapon, the U.S. made a deal with Saudi Arabia in 1974: the Saudis would sell oil only in U.S. dollars, and the U.S. would provide military aid. In return, Saudi Arabia would invest oil revenue in U.S. Treasury securities -- a secret arrangement not disclosed for over 40 years.
Oil is essential to the global economy. Even during the 2020 COVID-19 lockdowns, consumption only dropped from 100 million barrels per day to 80 million -- only 20% is discretionary. Because every country needs oil, and oil is priced in dollars, every country needs dollars. This perpetual demand created a network effect that reinforces the dollar's dominance through feedback loops and lock-in.
Why the Dollar Has Value¶
The dollar's value rests on several reinforcing foundations:
Legal Tender: Secured by the "full faith and credit of the United States," with legal enforcement mechanisms.
Network Effects: As more countries use dollars, the currency becomes more attractive to new users, creating a self-reinforcing cycle. Lock-in makes it difficult for alternatives to challenge the dollar's position.
Economic Seigniorage: Reserve currency status enables sustainable trade deficits (foreign countries need dollars) and lower borrowing costs (investors worldwide seek dollar-denominated assets).
Military Power: The U.S. Navy controls seven key global chokepoints essential for oil transportation: the Strait of Hormuz, Suez Canal, Strait of Malacca, Bab el-Mandeb, Panama Canal, Turkish Straits, and Strait of Gibraltar. Whoever controls these chokepoints controls the world's oil supply.
"WTF Happened in 1971?"¶
A popular website by this name documents dramatic economic changes since the gold standard ended: the share of wealth held by the top 1% more than doubled, household debt proliferated, asset bubbles emerged, and the dollar's purchasing power continuously declined. There is a strong case that abandoning gold brought change for the worse -- but an equally strong case that baby boomers entering the workforce and increasing output were equally significant drivers.
The Beginning of the End?¶
Several developments threaten the dollar's dominance:
U.S. Energy Independence: Since 2018, the United States has been the world's largest oil producer, reducing dependence on Middle Eastern oil and potentially weakening the petrodollar system's strategic importance.
Alternative Systems: BRICS nations (Brazil, Russia, India, China, South Africa) are coordinating to disconnect from the dollar network and establish alternatives. Blockchain technology makes this easier, but multi-currency systems have a history of failure.
Cryptocurrencies: Bitcoin and other digital currencies offer alternatives to state-controlled fiat money, though none yet challenge the dollar's dominance in international trade.
