When Interest Rates Built the American Empire
The dollar wasn’t America’s greatest export. Cheap capital was.
Forget tanks. Forget Silicon Valley. Forget Wall Street.
The real backbone of American power was far simpler it was the cost of money.
For an entire century, the interest rate wasn’t just a tool of monetary policy. It was a geopolitical weapon, a domestic growth engine, and the foundation upon which the American Empire was built. Cheap capital fueled its rise. Expensive capital enforced its dominance.
Every boom
Every bust
Every projection of U.S. strength abroad can be traced back to the pricing of capital at home.
The American Century wasn’t a story of factories, cultural influence, or military force
It was an interest rate story.
Bretton Woods: The Architecture of Dominance (1944–1971)
In 1944, America didn’t just win a war
it rewired global finance.
The Bretton Woods Agreement pegged global currencies to the U.S. dollar and the dollar to gold.
But beneath the surface, this wasn’t about stability. It was about control.
By anchoring the world’s monetary system to the U.S., America ensured one thing: the cost of capital everywhere would orbit around the Federal Reserve.
Low rates financed Europe’s reconstruction
Japan’s rise,
America’s suburban sprawl.
Mortgages, auto loans, consumer credit
all of it rode the wave of cheap money.
The world mistook it for generosity. It was strategic liquidity dominance.
The real export wasn’t the dollar.
It was capital itself.
The Inflation Spiral: When Complacency Breaks Stability (1965–1980)
But every empire’s strength plants the seeds of its own decay.
By the late 1960s, U.S. spending
warfare abroad (Vietnam)
welfare at home (Great Society)
exploded beyond what low rates could sustain.
The dollar’s gold peg cracked under the weight of fiscal indiscipline.
Nixon’s 1971 decision to sever gold convertibility didn’t trigger chaos.
It revealed it.
Inflation surged.
Rates were no longer an anchor they were adrift.
The world’s faith in America’s monetary leadership was fading.
The 1970s weren’t just an inflation story.
They were a story of rate power losing credibility.
And credibility in capital costs is the heart of empire.
Volcker’s Hammer: The Dollar Fights Back (1979–1982)
Paul Volcker didn’t “fight inflation.”
He reasserted U.S. rate supremacy.
By jacking the Fed Funds Rate to double digits, Volcker:
Crushed domestic inflation with a brutal recession.
Re-priced global capital flows, forcing emerging markets into dollar debt traps.
Restored belief in the dollar’s ability to dictate global liquidity.
Volcker’s rate hikes weren’t just a domestic policy choice.
They were a geopolitical act of aggression masked as monetary tightening.
He didn’t save the U.S. economy.
He saved America’s capital empire.
The Leverage Boom: Financialization as Power (1983–2007)
With inflation tamed, rates began a 25-year descent.
This was no accident. It was a deliberate choice.
As borrowing costs fell, America transitioned from industrial might to financial leverage.
The 80s corporate raiding era.
The 90s dot-com frenzy.
The 2000s housing boom.
All of it engineered on the back of cheapening capital.
The real economy took a backseat.
Asset prices became the growth engine.
Rates weren’t just the cost of money anymore they became the oxygen for risk.
The world flooded into U.S. assets because American rate policy seemed invincible.
That was the illusion.
Cheap capital isn’t growth. It’s just borrowed time.
The Gravity of Zero
By 2007, after decades of rate cuts, America’s empire was floating on air.
Capital was no longer scarce.
Risk was no longer priced.
Leverage was no longer disciplined.
Interest rates had built the empire. But by pushing them closer to zero, the foundation itself began to crack.
When risk costs nothing, stupidity gets subsidized.
Coming Next: When Interest Rates Tore the Empire Down
In the next essay, we’ll confront the inevitable.
How the Global Financial Crisis, Zero Interest Rate Policy, and the post-COVID regime shattered the illusion that cheap capital was free.
When money costs nothing, power becomes distorted.
And when that distortion unwinds, empires don’t fall
they cannibalize themselves.
