Dollar Hegemony Game
The Dollar Hegemony Game is Predictive History's game theory analysis of the US dollar system: the United States maintains global dominance not primarily through military force but through control of the world's reserve currency, compelling all nations to hold and transact in dollars, which requires them to export real goods and services in exchange for printed paper, a structural tax on global productivity that funds American military and consumer spending while trapping developing nations in permanent dollar dependency.
The puzzle that motivates this analysis: why do the best and brightest of developing nations spend more effort learning English than mastering their native language, obsess over accumulating US dollars rather than building local wealth, and prefer emigrating to America over achieving high status at home? The answer is not cultural aspiration but structural compulsion: the dollar system creates incentives that make these individually rational behaviors collective traps.
Since the Bretton Woods Agreement of 1944 and especially after Nixon's 1971 removal of the gold standard, the US dollar has served as the world's reserve currency, the currency in which most global trade (especially oil) is priced and settled, and which central banks must hold as foreign exchange reserves. This creates an extraordinary structural advantage: the United States can print dollars and exchange them for real goods and services from the rest of the world. Developing nations must earn dollars through exports, hold them as reserves, and use them for international trade, meaning they are permanently lending the US real value in exchange for paper it can create at will.
The oil-dollar nexus (petrodollar system) reinforces this: Saudi Arabia and OPEC price oil in dollars, meaning every oil-importing nation must first acquire dollars to purchase energy. This creates permanent global dollar demand regardless of US economic performance. Nations that attempt to price oil in other currencies (Saddam Hussein's Iraq in 2000, Muammar Gaddafi's Libya) have faced US military intervention, revealing that dollar hegemony is maintained ultimately by force, but the genius of the system is that military intervention is rarely needed because the incentive structure makes dollar compliance individually rational for every participating nation.

Frequently asked questions
What is dollar hegemony? ＋
The structural dominance of the US dollar as the world's reserve currency, which requires all nations to hold dollars and conduct major trade, especially oil, in dollars. This means developing nations export real goods for printed paper, permanently subsidizing American consumption and military spending. The petrodollar system (oil priced in dollars) ensures all oil-importing nations must continuously acquire dollars. Nations that attempt to escape this system, Iraq in 2000, Libya, have faced military intervention.
Why does the world continue to use the US dollar? ＋
Because it's a Nash equilibrium, no individual nation can exit without bearing the full cost of exit alone, while the system's disadvantages are shared broadly. Dollar pricing of oil means any nation exiting must still acquire dollars for energy. Dollar-denominated debt means debtors cannot escape without default. The network effects of the dollar system make unilateral exit irrational even for nations that understand the game, just as no individual firm can unilaterally exit a standards competition without competitive suicide.
