Eichengreen warns dollar faces Roman-style collapse

Friday, April 17, 2026 · from 3 podcasts
  • Currency historian Barry Eichengreen warns the dollar is melting like an iceberg, losing 0.5% reserve share annually.
  • Freddie New argues Western welfare states parallel Roman legions, guaranteeing terminal currency debasement.
  • The dollar persists as the cleanest shirt in a laundry basket of flawed alternatives.

Currency historian Barry Eichengreen warns the dollar’s dominance isn’t fading overnight - it’s thawing. He frames reserve status as a promise of stability anchored in democratic institutions, citing the Roman denarius’s 80% to 5% silver decline as a historical template. The dollar currently clings to roughly 60% of global reserves, down from over 70% in the late nineties, losing about 0.5% of its share each year.

“Dominant currencies erode slowly for decades before collapsing in sudden, violent chunks.”

- Barry Eichengreen, Bankless

Eichengreen argues the dollar’s primary rival isn’t China’s renminbi, but institutional decay at home. The currency’s strength relies on an independent Federal Reserve and a rule of law investors trust. On The Peter McCormack Show, Freddie New deepens this analogy, drawing a direct parallel between modern welfare states and Roman legions - both as captive constituencies that demand perpetual funding. He notes the British pound has lost 95% of its value in the last century, matching the denarius’s 150-year death spiral.

New sees collapse not as a riot, but as unmaintained roads and nihilism. When inflation hollows out honest labor, people retreat into digital fantasies. Eichengreen agrees the dollar’s fall wouldn’t crown a single successor but fragment the system toward gold, middle-power currencies, and digital assets, ending the ‘exorbitant privilege’ of cheap crisis insurance.

“Western governments have replaced Roman legions with a welfare-dependent class to secure political power.”

- Freddie New, The Peter McCormack Show

The euro lacks a unified treasury; the renminbi lacks political transparency. Eichengreen calls this the ‘cleanest shirt in the laundry’ theory, forcing the world to stick with the dollar by default. Yet he warns that default status isn’t a shield. If confidence in the U.S. Treasury breaks, capital will flow out, driving interest rates up and crashing local markets. The question is whether the melt remains gradual or snaps.

#166 - Freddie New - How Governments Destroy Money and Empires (The Lessons From Rome)Apr 16

  • New cites that the pound sterling has lost 95-96% of its purchasing power over the last 100 years, a rate of decline worryingly similar to that of the late Roman Empire.
  • New identifies Emperor Diocletian as a historical parallel to modern politicians advocating price controls, noting his Edict on Maximum Prices was unenforceable and created a black market.
  • New highlights Emperor Constantine's introduction of the gold Solidus, which maintained its purchasing power for 700 years, as a historical example of a successful return to hard money after crisis.
  • McCormack argues the fundamental problem is the dissociation of money creation from value creation, where central banks and commercial lending create money 'out of thin air,' leading to asset inflation like runaway house prices.

Protocol (4)

  • Freddie New draws a parallel between modern fiat debasement and the Roman denarius, which lost 97% of its silver content and purchasing power over 150 years from Marcus Aurelius to Diocletian.
  • New argues the military was the Roman emperor's key constituency, just as the modern welfare-dependent class and state workers are for today's governments. Both groups demand continuous payments, forcing currency debasement to maintain political power.
  • Peter McCormack points to UK welfare spending of £333 billion, which now exceeds the £331 billion raised from income tax, illustrating the state's reliance on a dependent population.
  • New states Roman currency debasement began with coin clipping, progressed to silver dilution, and led to soldiers demanding higher nominal pay as the real value of their coins fell, creating an inflationary spiral.

Society (1)

  • McCormack reads a 2013 passage describing societal collapse as a hollowing-out process: shrinking homes, longer work hours, declining real pay, eroded standards, and a population engrossed in technological distraction.

Agents (2)

  • Both hosts discuss AI agents as a technological step change, with New's agent autonomously making Lightning Network payments and McCormack's automating web tasks, though McCormack fears it increases productivity pressure rather than leisure.
  • New suggests the AI agent economy will drive significant demand for the Bitcoin Lightning Network, as agents cannot traditionally pass KYC but can transact peer-to-peer using Bitcoin.

History (1)

  • The conversation turns to the Roman Republic's system of two consuls with one-year terms and the office of 'dictator' - a temporary, absolute power granted in crises, exemplified by Cincinnatus, who relinquished power after resolving a military threat.

Why Hasn't The Dollar Fallen? | Lessons from Currency Historian Barry EichengreenApr 16

  • Barry Eichengreen argues the dollar is in the early stages of its decline as central banks diversify from US Treasuries into gold and non-traditional reserve currencies.
  • Spanish silver coins were legal tender in the United States until 1857. They dominated early American commerce due to a British prohibition on colonial mints and immense silver deposits in Peru and Mexico.
  • Eichengreen says a currency becomes international through economic factors like trade volume and liquid capital markets, plus political factors like rule of law, checks on executive power, and strong alliances.
  • International currencies fall due to economic decline, military defeat, or currency debasement, often with long lags between economic decay and loss of status.
  • Dollar dominance is fraying, with its share of central bank reserves dropping about half a percentage point annually from over 70% twenty-five years ago to under 60% today.
  • Eichengreen sees two scenarios for the dollar: a gradual decline allowing alternatives like the euro to develop, or a rapid crisis if foreigners deem US leadership unstable, causing market dislocation.
  • Current dollar dominance metrics include invoicing 40% of global trade, linking to 50% of global GDP, and involvement in 90% of foreign exchange transactions.
  • Gold serves as a reliable store of value and collateral, but its physical weight makes it impractical for active payments if removed from financial centers to avoid sanctions.
  • His investment advice for a potential monetary transition is diversification, noting shifts between dominant currencies are rarely smooth.

History (2)

  • Spanish silver became the first global currency, circulating on every continent via transatlantic and transpacific trade routes like the Manila galleons.
  • The Byzantine solidus was a stable gold coin with a 700-year reign, surpassing even the 1950s US dollar in stability according to historian Robert Lopez. Eichengreen credits Byzantine fiscal prudence.

Politics (2)

  • Military security is a common but not universal prerequisite for international currency status, protecting borders and trade routes. Florence's florin succeeded through finance and trade alone.
  • Eichengreen says every leading global currency except the Spanish dollar belonged to a political democracy or republic, a challenge for China's renminbi aspirations due to arbitrary rule under Xi Jinping.

Digital Sovereignty (1)

  • Eichengreen argues digital technology weakens network effects that favor a single currency, making it easier to use and exchange different currencies instantly.

Trade (1)

  • He doubts the renminbi will achieve global status due to China's lack of rule of law and its geopolitical rivalry with the West, though it may gain regional use among allies.

AI Infrastructure (1)

  • Eichengreen believes blockchain payment rails will be most consequential, likely running central bank digital currencies and tokenized bank deposits rather than volatile cryptos like Bitcoin.

The Rise of History’s Greatest Emperor: An Untold Story - Alex Petkas - #1085Apr 16

Also from this episode: (16)

History (16)

  • Alex Petkas argues the value of history is not in accumulating facts, but in finding monumental examples of greatness that provide personal resonance and direction for one's own life, a perspective he traces to Nietzsche's reading of Plutarch.
  • Petkas cites Julius Caesar crying before a statue of Alexander the Great at age 30, lamenting his lack of comparable achievement. This moment represents a painful realization of unfulfilled potential and a catalyst for ambition.
  • Caesar grew up in a politically divided Rome, aligned with the populist faction through his uncle Gaius Marius. His family had ancient lineage but was not part of the contemporary power elite, living in the seedy Subura district.
  • At 18, Caesar defied the dictator Sulla's order to divorce his wife Cornelia, the daughter of a populist enemy. This act of loyalty and defiance marked his early commitment to the populist cause and nearly got him executed.
  • When captured by pirates, Caesar insisted they double his ransom to reflect his higher worth. After his release, he raised a fleet, captured the pirates, and crucified them, demonstrating his blend of theatricality, political savvy, and ruthless follow-through.
  • Caesar cultivated popularity through personal style, prosecuting corrupt governors, and championing anti-establishment justice. His early prosecution of the elderly Rabirius for events 30 years prior was a symbolic statement against oligarchic impunity.
  • Petkas describes extreme loyalty from Caesar's soldiers, citing the centurion Granius Petro who stabbed himself rather than accept mercy from an enemy commander, declaring it was the custom of Caesar's men to give mercy, not receive it.
  • During a grueling siege against Pompey, Caesar's starving soldiers catapulted loaves of inedible weed-cakes into the enemy camp to demonstrate their resolve, prompting Pompey to remark they were fighting beasts.
  • Caesar generated loyalty by fighting in the front lines, knowing his centurions by name, and sharing the same hardships as his troops, including sleeping on the ground and eating rancid food.
  • The First Triumvirate was Caesar's brokerage of a deal between rivals Pompey and Crassus, leveraging their mutual needs to secure their support for his consulship, after which he passed legislation benefiting them both.
  • The death of Caesar's daughter Julia, who was married to Pompey, severed the key personal bond between the two men, making the political rift that led to civil war more likely.
  • Caesar crossed the Rubicon River into Italy with one legion, initiating civil war after the Senate declared him a public enemy. His speed and the element of surprise were key advantages against a larger but unprepared opposition.
  • After defeating Pompey at the Battle of Pharsalus, Caesar pursued him to Egypt, where Ptolemy XIII's advisors had Pompey murdered to curry favor. Caesar was reportedly angered by this, as he wanted to pardon Pompey.
  • Cleopatra famously had herself smuggled to Caesar rolled in a carpet. Petkas notes she was a politically astute, multilingual ruler who understood how to appeal to Caesar's weakness for intelligent, high-status women.
  • Caesar refused a bodyguard despite known assassination plots, believing it was a tyrant's move. On the night before his death, during a philosophical discussion on the best kind of death, he argued for one that was sudden and unexpected.
  • Decimus Brutus, a close lieutenant and heir in Caesar's will, convinced him to ignore bad omens and his wife's warnings and attend the Senate on the Ides of March, where the assassination was carried out at the base of Pompey's statue.
