LSE: Public Lectures and Events

Episode: "Our Dollar, Your Problem" – Kenneth Rogoff

Date: January 29, 2026
Host: Ricardo Ghujs, A.W. Phillips Chair in Economics at LSE
Speaker: Professor Kenneth Rogoff, Moritz Boas Professor at Harvard University

Overview

This episode features Professor Kenneth Rogoff discussing his book Our Dollar, Your Problem, which provides an insider’s perspective on the US dollar's dominance in global finance over seven decades and the road ahead. The talk explores historical context, shifting global power dynamics, challengers to dollar supremacy, financial innovations (like stablecoins and cryptocurrencies), and looming risks—both internal and external—to US dollar hegemony.

Rogoff draws on history, personal anecdotes, academic research, and current events to provide a sweeping analysis of how and why the dollar has remained preeminent, why this may change, and the profound implications for the global financial system if it does.

Key Discussion Points & Insights

Genesis of the Title and Historical Parallels

• Origin of the Title: The phrase “Our Dollar, Your Problem” was coined by John Connally, Nixon’s Treasury Secretary, reflecting US arrogance towards international concerns about dollar policy.
  • “I think that episode sort of spoke to me and partly why I chose the title because I didn't like the arrogance of it. We Americans are arrogant. I don't need to tell you that. But I didn't like it.” (10:22 – Rogoff)
• Nixon and Trump Comparison: Rogoff sees similarities between Trump and Nixon, especially in terms of their attitudes toward financial system priorities and use of power.

The Dollar’s Evolution and Global Role

• Post-War System: After World War II, the financial system was deliberately rebuilt with the US at its core—currencies pegged to the dollar, which was in turn backed by gold.
• Abandoning the Gold Standard: Nixon ended dollar convertibility to gold in 1971 without any planned solution for inflation—causing uproar among major trading partners.
  • "In mid August of 1970, [Nixon] said, no more. We won't trade the dollar for gold. And the Europeans were furious..." (08:00 – Rogoff)
• Persistence of Dollar Dominance: The US has maintained a surprisingly high share of global GDP, partially due to network effects and first-mover advantages in modern technologies.
  • “Nobody, and I mean nobody, thought that would happen... It’s a surprise.” (13:55 – Rogoff)
• Various Measures of Dominance: Trade invoicing, central bank reserves, financial instrument denomination, and exchange rate anchoring all reflect dollar dominance—though metrics vary.

The Global Dollar Zone and Its Shifts

• Colonization of the World: Over decades, America's dollar-centric approach "colonized" global finance, except for historic outliers like the Soviet bloc and French franc zone.
• Recent Decline: The dollar’s centrality has been in “gentle decline,” especially as Asia—particularly China—loosened their dollar pegs and US sanctions prompted diversification.
  • “The US... very promiscuously uses financial sanctions. And I'll come back to that. We also use the financial system for spying…” (19:20 – Rogoff)

Advantages and Complaints about Dollar Dominance

• US Exorbitant Privilege: The US enjoys lower interest rates thanks to global demand for the dollar. It controls the “back office” of much of the global financial system, reinforced by its military and geopolitical leverage.
  • “Most economists would regard being the currency everyone's using as an incredible advantage.” (21:34 – Rogoff)
• Foreign Criticism: The French termed this the “exorbitant privilege,” lamenting the unfairness of being forced to hold dollars and endure US policy choices.

Challengers to the Dollar

• Historic and Current Challengers:
  • Soviet Union/Russia: Expected to become preeminent; did not happen.
  • Japan: In the 1980s, its stock market and per capita income rivaled the US; the Plaza Accord (1985) forced yen appreciation and, Rogoff argues, undercut Japan’s challenge.
    • "If you talk to any major Chinese policymakers... they have said for decades, we will never, never, never allow the US to do to us what you did to Japan." (32:19 – Rogoff)
  • Euro: Despite early skepticism, the euro achieved significant global trading and reserve status, briefly threatening dollar share until internal crises and inclusion of weak members (notably Greece) set it back.
  • China: Massive real estate boom created systemic risk. Rogoff’s research predicts a drawn-out slowdown, delaying China’s challenge.
    • “China's housing is worth more than the US… but [prices]…in free fall and that's why China's having a recession.” (37:52 – Rogoff)
  • Cryptocurrencies: The underground and illicit economy increasingly uses cryptocurrencies and stablecoins, sometimes for large-scale transactions (including terror financing).

Financial Sanctions & Technology ("The Rails")

• US Leverage: Much of the world's financial clearing runs through US-controlled systems, allowing effective sanctions and monitoring—constituting a "sticky" barrier to change.
  • Modern technology is enabling parallel payment and clearing networks, especially in China, which may erode this control in the future.

Financial Innovations and Risks

• Stablecoins & CBDCs: Stablecoins are the “killer app” of crypto thus far, making some cross-border transactions less visible. Their future is heavily dependent on regulatory environments; they're not as government-resilient as crypto-liberals hope.
• Cryptocurrency Use in Practice: Rogoff and colleagues have forensically traced large-scale, cash-based cryptocurrency transactions in crisis economies—demonstrating real, if often illicit, demand.

Central Bank Independence & Internal US Risks

• Key to Trust in Dollar: The Fed’s independence is the global anchor of trust in the dollar. Rogoff warns that overt politicization (as advocated by Trump) could destabilize this system and stoke inflation expectations.
  • “Trump says he wants interest rates to be lower even though it seems like he would get inflation… And if you do that it undermines the system.” (49:44 – Rogoff)
• Swap Lines as Geopolitical Tool: The Fed's dollar swap lines can be turned on and off for foreign central banks, potentially weaponized by a politicized US administration.
• US Debt Burden: With US government debt at record levels, Rogoff describes the US as “holding its breath;” rising interest rates could trigger fiscal stress and further pressure the dollar.

Interest Rates, AI, and Global Pressures

• Structural and Demographic Shifts: Debates over whether demographic shifts guarantee low interest rates miss the point—historical cycles show variability, and pressures (like defense spending) may soon push rates up.
• “AI Will Save Us?”: While AI and technological advances could boost productivity, Rogoff urges skepticism about counting on them to offset structural fiscal challenges.

Audience Q&A—Selected Insights

On Central Bank Independence and Commitment Devices

• Commitment devices, especially for monetary policy, have worked reasonably well—less so for fiscal policy.
• Central bank independence looks fragile under political pressure; Trump’s intimidation of Fed officials is a real concern.
  • "He does a lot of things... mafia-like things to intimidate... he actually much more significant as he subpoenaed Jerome Powell..." (59:11 – Rogoff)

On Dollar “Challengers” and Oil Invoicing

• Changing oil pricing from dollars is symbolically important, but not fundamentally disruptive; trade in goods with sticky prices matters more.
• China has been successful in getting more trade invoiced in renminbi, but progress is evolutionary.

On Stablecoins:

• Stablecoins are important financial innovations, but their widespread use for illicit and untraceable transactions is unsustainable; future regulation will blunt their appeal/opacity.

On the Euro’s Prospects:

• Market clearing infrastructure (the “rails”) is crucial—developing alternatives to US-dominated systems is essential for real euro or renminbi competition.

On Precious Metals and the Search for Safe Havens:

• Demand for gold and other real assets rise as faith in US policy and dollar stability wobbles; central banks are diversifying reserves as a hedge.

On Bilateral Trade Agreements (e.g., Mercosur, India):

• New agreements are reactions to US policy unpredictability; helpful for diversification but not immediate threats to dollar dominance.

On Central Bank Reserve Alternatives:

• The euro has gained, even as the dollar appreciates. Gold and some other assets are reasonable hedges, but options are limited—systemic dollar decline would produce instability, not a quick switch.

On the Direction of Change:

• Dollar dominance will erode slowly, primarily undermined by internal US policy mistakes (central bank politicization, fiscal irresponsibility), but external competition (China/euro, tech innovation) accelerates the process.

Notable Quotes & Memorable Moments

• On stablecoins and regulation:
  • “Stablecoins are a substitute for credit cards, debit cards, checks, everything. And it makes transactions very, very difficult to audit… there's a future for stablecoins but they're going to be much less government resilient than people think.” (57:45 – Rogoff)
• On Trump and Fed independence:
  • “He does a lot of things… mafia-like things to intimidate... I think he’s going to get operational control eventually.” (59:11 – Rogoff)

Tone and Language

Kenneth Rogoff’s style was lucid, conversational, often wry, and accessible—even as he engaged with advanced economic theory and data. He mixed academic rigor, historical anecdotes, and personal stories (e.g., chess, family history, experiences with world leaders). His approach was self-deprecating, freely admitting past mistakes in judgment and “changing his mind” on challenging questions, reinforcing an atmosphere of lively, honest debate.

Summary

Kenneth Rogoff’s lecture takes listeners on a thoughtful, nuanced tour of the rise and potential fall of dollar supremacy. He makes clear that while external challengers like China and the euro matter, internal dynamics—particularly politicization of central banking and fiscal imprudence—pose the greatest threat to dollar dominance. The consequences of a faltering dollar, however, will be system-wide instability rather than an orderly transition to a new hegemon. In the coming era, gold, digital assets, and regional agreements will play growing roles—but the world will need to look beyond nostalgia and arrogance to manage this uncertain transition.
