Kenneth Rogoff (Harvard University): "The dollar will always be there, but it will be less."

The Soviet economy failed partly because it lacked market prices to aggregate into GDP measurements, which created room for creative accounting and made it impossible to assess true economic performance using standard metrics, unlike market economies where prices reveal real productivity.

“if you're not a market economy where you can aggregate prices That's how we measure income. You take the uh computers and you add the uh meat and steel and you add it all up at market prices to form what your GDP is. Well, they didn't have market prices which left a lot of room for creative accounting.”

The Plaza Accord (1985) forced Japan to appreciate the yen by 50% (not the negotiated 10%), which triggered massive capital inflows Japan was unprepared to regulate, creating asset bubbles and banking system fragility similar to the 2008 US financial crisis.

“Jean Clutch, the former uh head of the European Central Bank, showed me actually the whole agreement, the numbers they picked. They picked that they would appreciate make their currency stronger by 10%. It doubled. It It didn't just increase by 10%.”

Data collection limitations on the Soviet economy (deliberate opacity and lack of market prices) made it impossible to accurately measure Soviet GDP and economic health, leaving 'a lot of room for creative accounting' even for serious scholars.

“Well, they didn't have market prices which left a lot of room for creative accounting. But but it wasn't just that. I mean, you know, visibly Russia, you know, put a man in space ahead of the United States. They were very good in physics and many other math, many other fields.”

Near-term future (rather than crypto dominance) will likely feature greater volatility in global financial markets, with a decline in the 'pax dollar' (dollar-backed stability in global finance) driven by resurgence of political economy constraints on central bank independence.

“I I mentioned earlier in this uh talk our discussion that I thought we reached peak dollar actually 10 years ago. It's not now. But I have another phrase I introduce which is pox dollar p a x not poo x p a x which is it's on the whole you know been pretty stable in global financial markets... I have a a Brookings paper uh with a couple few great co-authors from earlier a year ago, I guess, uh talking about why that's not that's nonsense. We lived in the special globalization era where it was easy for central banks to be independent, but the political economy is going to come back with a vengeance.”

Tariffs and trade barriers reduce financial integration and investment flows; to the extent that tariffs suppress trade volume, they reduce the benefits of financial openness that have been central to US global dominance, accelerating dollar decline faster than would occur from other causes.

“If uh we have a lot of tariffs making it expensive to get money in and out of the country, assuming counterveailing tariffs, you don't invest as much. I mean, again, I go back to my six puzzles paper for those academics of you in 2001 with Oddsfeld. You don't integrate as much financially.”

Paul Samuelson and other leading 20th-century economists predicted in the early 1970s that the Soviet Union would economically catch up with the United States between 1987 and 1994, suggesting the ruble could become a significant global currency, based on simple extrapolation of Soviet growth trends without adequate data on the Soviet economy's structural problems.

“Paul Samuelson uh and he his textbook which was read by everybody predicted that the dollar would uh the r not not that the ruple would catch up with the dollar but that Russia was going to catch up as an economy with the United States... predicting the catchup sometime between I think 87 and 94.”

The US currently has enormous public debt outstanding, and if the US had Germany's debt level (lower), US interest rates would be significantly lower even controlling for dollar dominance, meaning the burden of US debt service is substantial and limits the conventional interest-rate advantage from dominance.

“we issue the United States I'm an American we issue a ton of debt and our interest rate on 10-year bonds actually really isn't lower than other countries now controlling for you know various ways of trying to hedge but we have a ton of debt out if we had Germany's debt level our interest rates would be a lot lower”

Russia had visible spectacular accomplishments in space exploration, physics, mathematics, and other fields that made the outside world believe the Soviet economy was functioning well, even though these were not representative of the broader economy's actual health.

“visibly Russia, you know, put a man in space ahead of the United States. They were very good in physics and many other math, many other fields. They had a lot to to the outside eye, they had a lot of spectacular accomplishments.”

A closed economy cannot maintain wealth without incurring vast losses; the idea that the US can return to a more insulated economy without sacrificing living standards is fundamentally unsound.

“the idea that you can become a much more closed economy without losing wealth vastly is just nonsense. I mean, you can't turn it back.”

Currency dominance shifts typically unfold over two decades, not centuries or overnight: 'it could happen over a couple decades. It doesn't take a century but it doesn't happen overnight.'

“it could happen over a couple decades. It doesn't take a century but it doesn't happen overnight”

John Connally, Nixon's Treasury Secretary during the 1971 end of the Bretton Woods gold standard, told foreign governments complaining about the dollar's instability: 'It's our dollar. It's your problem.'

“And he said, "It's our dollar. It's your problem."”

Howard Baker (Reagan's Treasury Secretary) told a European finance minister who threatened to stop holding dollars: 'I grew up in Texas and my daddy taught me if you pull a gun on somebody, you better be prepared to shoot,' illustrating the assertive posture of US financial dominance in the 1980s.

“and Baker supposedly looked at him and said, you know, you know, I grew up in Texas and my daddy taught me if you pull a gun on somebody, you better be prepared to shoot.”

The host (from ex-Soviet block background) recalls that even in the Soviet Union, people knew the ruble was artificial and that everyone wanted dollars instead, suggesting local knowledge contradicted official claims about the convertible ruble's utility.

“inside we were all sort of like laughing at it that was just of a sort of a fig leaf that everybody wanted a green back.”

The US was bullying Europe into supporting Iran sanctions (post-2005 Iran nuclear standoff) despite disagreement, using threat of financial system exclusion, similar to how it later bullied Japan into currency appreciation.

“the Europeans were quite upset about Iran when we put sanctions on Iran and the Europeans didn't agree with it and uh you know back 10 years ago and we bullied the Europeans and to go along with it we said okay you know if you play with Iran you can't use our financial system.”

Economists' 1990s prediction that there would emerge three regional currency blocks (euro, dollar, yuan/remnibi) failed because Europe lacked the military power to maintain a currency block, even with an economically strong euro.

“a whole bunch of authors wrote about this uh brilliant economist but Barry Iiken Green at Berkeley uh a Nobel Class uh economic historian Jeff Frankle uh one of the top international economists many many others predicted 15 years ago that we would go to a situation where there was a euro block a dollar block and an R&B block which is we may go to but uh We didn't. And what was so naive about this is you don't get to have a a currency used outside your area if you don't project military force.”

Rogoff's 'Six Puzzles' paper with Mory Obstfeld from 2001 explained the mechanisms by which reducing trade barriers and increasing financial integration create demand for the dominant currency and support its dominance; conversely, tariffs reduce both forms of integration.

“My six puzzles paper with Mory Obsfeld 25 years ago is all about that. Take away some of the demand that pushes up interest rates. But it also affects our ability to see everything...I go back to my six puzzles paper for those academics of you in 2001 with Oddsfeld. You don't integrate as much financially.”

Dollar dominance provides the US with control over global financial rules (IMF governance, SWIFT operations, market-clearing mechanisms), which conveys geopolitical power far beyond mere currency convenience.

“if you're the uh uber dominant uh currency, if you're the uber dominant military power, you have a lot of control over the rules of the game. What are the rules of the IMF? How does Swift work? Uh how does market clearing work? That that's I think a thing very few people understand when they talk about dominant currency. They're just thinking about convenience. No, we make rules so [11:30] that it favors us a lot and we have a lot of control over that because both of the dominance of the dollar and the military dominance”

Rogoff initially believed Japan's crisis was not caused by Plaza Accord because it occurred 5-6 years later and Japan boomed in the interim (stock market tripled, housing appreciated), but later revised this view: the delay was the point—structural imbalances take time to unwind.

“I try to pick some things in the book where I feel like I was wrong. And this is one of these episodes where I talk about that... You are not going to do this to us. We are not going to let you bully us... I realized that we bullied them into doing something they weren't ready to do.”

Economists and financial analysts have a systematic tendency to extrapolate short-run trends and assume they will continue forever, missing inflection points; this error is particularly common in prestigious economic journals like the American Economic Review.

“economists have this in and and uh financial analysts and uh the media have this tendency to extrapolate very shortrun trends and think that they're going to go on forever. And I had felt I had identified a number of u dubious ones that had been the focus... One is interest rates will be low forever. One is China will grow, you know, to the clouds. And another was the dollars forever.”

In financial crises and recessions, the dollar appreciates (capital flight to safety), but the US simultaneously suffers capital losses on its foreign assets holdings because asset prices in other countries fall, creating a negative wealth effect that offsets apparent currency strength.

“the dollar in a panic, the dollar goes up, but when we're in a uh we're in a recession, uh I'm sorry. Um I it is true that in a recession the dollar goes up, but we're losing money in our investments in the rest of the world. I'm twisting on my own ideas. So actually when there's a recession the US gets capital losses on its holdings in the rest of the world not even counting the stocks dropping.”

Dollar dominance provides the US with control over the rules of global financial institutions (IMF, SWIFT, market-clearing mechanisms) and this rule-setting authority is a primary benefit, separate from the convenience of currency use, and losing dominance means losing this control.

“if you're the uh uber dominant uh currency, if you're the uber dominant military power, you have a lot of control over the rules of the game. What are the rules of the IMF? How does Swift work? Uh how does market clearing work? That that's I think a thing very few people understand when they talk about dominant currency. They're just thinking about convenience. No, we make rules so that it favors us a lot”

Trump's tariff policies, if they include significant countervailing tariffs from trading partners, will reduce investment and financial integration, shrinking the footprint of dollar dominance because tariffs discourage capital flows into and out of the US.

“If uh we have a lot of tariffs making it expensive to get money in and out of the country, assuming counterveiling tariffs, you don't invest as much... You don't integrate as much financially.”

The Soviet Union's collapse was shocking and unexpected, even though there were some warning signs, illustrating that confident extrapolation of the status quo ('nothing could ever change, things will always be the way they are') fails to anticipate fundamental transitions.

“We started with the Soviet Union. I I didn't know the Soviet Union would fall. I I had no idea when that happened. I was very surprised. I mean, maybe not by the day. There were a few warning signs, but it was just shocking the the idea that nothing could ever change. Things will always be the way it is.”

John Connally, Nixon's Treasury Secretary, told foreign governments that faced with the US abandoning the gold standard in 1971 that 'It's our dollar. It's your problem,' exemplifying American arrogance about dollar dominance, though Rogoff notes the irony that the resulting inflation became America's problem too.

“He sent John Connelly there and he said, they said, 'What are we supposed to do?' And he said, 'It's our dollar. It's your problem.'”

The Bretton Woods system under which the dollar was convertible to gold for governments was successful for Europe, which 'grew like gangbusters' during this period, but the US decided to expand social programs and wage the Vietnam War, creating inflation that became incompatible with gold-standard constraints.

“your Germany your France you would uh stabilize your currency to the dollar and you held a lot of dollar treasury bills not cash to do that and you know it had its problems but let's face it Europe grew like gang busters during that period. It was a successful period, but the US decided to expand our social programs, invade, you know, have the Vietnam War, many other things. And we were starting to get inflation. And if you want to fix your currency to gold and have inflation, it's not consistent because gold's not inflating.”

Economists have long debated whether currency interventions can actually move exchange rates, and when Rogoff was at the Fed working on Plaza Accord background research, there was significant doubt about whether governments could engineer large currency appreciations.

“I won't I won't say we said they couldn't do it, but we we had our doubts... when I was at the Fed and we were trying to ask ourselves, can currencies really be moved around through intervention?”

The US has substantial economic advantages in energy (among the world's largest oil and gas producers), arable land quality and quantity, the ability to absorb and integrate immigrants (due to cultural acceptance and space), and technological capacity, which create structural competitive advantages independent of dollar dominance.

“But I I think you hit the nail on the head with the core point is the US has just incredible economic advantages. We do we are actually probably at the moment the world's biggest oil producer and uh way up there in other in other things and that makes us more independent. Uh we have incredible farmland. We have uh incredible um ability to absorb immigrants both in terms of land. I mean Japan doesn't they don't have land and also a culture although which is more accepting of immigrants.”

The European Union weaponized currency reserves and sanctions against Russia following Ukraine invasion, accelerating European recognition that dollar dominance carries geopolitical costs and vulnerability, though some nations (Iran, others) had already experienced this dynamic from earlier unilateral US sanctions.

“especially for Europe, the sort of the realization of of what the dominance of dollar brings came when uh when when the uh when sanctions were actually weaponized when the currency reserves were weaponized after Russia's invasion of of Ukraine. Although there were as you mentioned there are some other nations around the world who who who have not been happy with the dollar's dominance because they faced sanctions for other reasons elsewhere just you know an example of Iran”

Paul Samuelson, one of the two or three most famous economists of the 20th century, predicted in his textbook that Russia would catch up with the United States economically, with implications for ruble dominance in the global economy, based on extrapolation of Soviet growth trends.

“Paul Samuelson uh and he his textbook which was read by everybody predicted that the dollar would uh the the r not not that the ruble would catch up with the dollar but that Russia was going to catch up as an economy with the United States”

Despite having significant structural advantages, the U.S. can 'throw them out the window' through bad policy, meaning that structural advantages are necessary but not sufficient to maintain economic dominance without wise governance.

“So we we have a lot of great advantages but you know you can throw them out the window.”

US defense spending as a share of GDP is approximately one-third of what it was at the end of the Cold War (1980s-early 1990s), making it impossible to defend the South China Sea, intervene in the Middle East, and support Ukraine simultaneously.

“Our defense budget is, you know, like a third of what it was when the Cold War ended at the end of the 1980s as a share of GDP. We can't defend the South China Sea, intervene in the Middle East, uh, in Ukraine. Forget it.”

Commodities are traded approximately 80% in dollars (not 100%), and China is actively working to shift commodity pricing toward other currencies, which will occur but is not a terribly significant threat to dollar dominance because commodity prices are flexible regardless of denomination.

“So, commodities are traded in dollars and uh mostly it's actually probably about 80% in dollars. It's not 100%. But the Chinese are moving to change that... It's not a terribly big deal at some level because commodity prices are so flexible that what you price them in. It's a little bit like I go to buy something in the store and am I paying with Visa or Mastercard? It doesn't matter that much.”

Most central banks achieved independence over the last 25 years and policymakers assume this independence is permanent because it has existed for 20-25 years, but this is a false sense of security—independence is not a natural state and can be reversed.

“people uh most bank most central banks weren't I'd say over the last 25 years now most countries do and people just take it for granted been there for 20 years 25 years it will always be independent. That is just nonsense.”

Rogoff himself had doubts (along with Howard Baker and others at the Federal Reserve) about whether currency intervention could actually move exchange rates, but the Plaza Accord succeeded in moving the yen far more than expected, suggesting that currency movements are possible through coordinated intervention but with uncontrollable magnitude.

“I worked on the Plaza core background stuff when I was at the Fed and we were trying to ask ourselves, can currencies really be moved around through intervention? Is it really possible? How is it possible? So, we we released a book. I have a paper, you know, back then. And I I said, you know, we I won't I won't say we said they couldn't do it, but we we had our doubts. And he said, yeah, um you know, [22:26] we were we weren't sure either what they were going to do, but the Japanese finance minister uh said to me, I can't make this decision myself...we had to, you know, fly back to Tokyo and uh two weeks later they got the message, we're going to make it happen. And they did.”

Japanese auto manufacturers responded to US tariff pressure and yen appreciation (1980s) by building manufacturing plants in the US, eventually becoming the largest auto producers in America when measured by aggregate sales across all brands.

“there was this attempt to restrict imports of Japanese cars but what happened the Japanese started making cars in the US and now as an aggregate they seem to be maybe I don't have the latest figures in front of me but they seem to be the biggest the biggest car maker you know if you combine all the brands”

Pressure on Federal Reserve independence and rule of law has come from both political sides (Democrats and Republicans) even before Trump, and these pressures will continue regardless of who is in power, reflecting a deeper erosion of institutional norms.

“there's a lot of pressures to undermine the Federal Reserve, uh pressures on protectionism, pressures on the rule of law coming from both sides.”

The dollar's global dominance peaked approximately 10 years ago (around 2014-2015), measured by the share of countries that stabilize their exchange rates against the dollar, with Asia's dollar-block share declining from over 50% to lower levels as China moved away from dollar pegging since 2015.

“my view looking at a historical perspective post World War II and also thinking about the economics underlying it is that the dollar peaked maybe 10 years ago in terms of its global footprint and just to think about that Asia's 50% of the the dollar blocked by the measure I use with Ethan Ozitki and Carmen Reinhardt... China sort of has been moving away from that since 2015.”

Rogoff's method is to examine very long time periods rather than recent decades, because typical academic papers in economics journals (American Economic Review) focus on recent 20-30 year windows and thereby miss major turning points and structural changes that only become visible on century timescales.

“What I do in my work, and also it's a big theme in the book, is look at really long time periods. Don't just look at the last 20 years, the last 30 years. And by the way, the typical American Economic Review paper does that. You're missing everything.”

International diversification, particularly exposure to non-US assets, has appeared to be a bad investment until recently (when US assets underperformed), but Rogoff argues it is actually a sound strategy and will be recognized as such once the period of US exceptionalism ends.

“I have long thought that international diversification was good and that has seemed like the dumbest idea until maybe it's not. Those ideas just you can't invest enough in America.”

China and the US will both resist currency revaluation because it undermines their economic position; both countries have explicitly stated they will not allow themselves to be bullied into currency appreciation, having observed the consequences Japan faced after the Plaza Accord.

“the Japanese, the Chinese talk about this all the time. You are not going to do this to us. We are not going to let you bully us. And that's playing out before our eyes.”

Rogoff has been debating the question of real interest rates for 15 years, arguing that low rates are not a permanent feature, while prominent economists including Larry Summers, Paul Krugman, and Olivier Blanchard have argued that low real rates will persist; this is relevant to both investors and public debt policy.

“I think it's very important to think about that. So, I think that's what motivated me really. I felt and it's somehow hard to get anybody to listen to you because you're saying something different than people want to hear. Uh so the interest real interest rates as an example where I've been debating that for 15 years saying interest rates were low but if you look historically they weren't always why would you think as Larry Summers Paul Krugman Olivier Blanchard and not to mention many finance ministers politicians they're just going to keep going down that's relevant to investors it's very relevant to public debt.”

In a recession, the dollar appreciates even as US investors suffer capital losses on foreign holdings; the dollar's safe-haven status during panics creates real losses for US investors despite nominal strength, an asymmetric cost of dominance documented in papers by Tarek Hassan, Elaine Ray, and others.

“well you have to be prepared to take it on the chin in a recession and the obvious point about that would be that the dollar in a panic, the dollar goes up, but when we're in a uh we're in a recession, uh I'm sorry. Um I it is true that in a recession the dollar goes up, but we're losing money in our investments in the rest of the world. I'm twisting on my own ideas. So actually when there's a recession the US gets capital losses on its holdings in the rest of the world not even counting the stocks dropping.”

Central bank independence, which was rare or nonexistent 30-40 years ago, has become taken for granted by modern policymakers and the public, who assume it is permanent and will always exist, but this is a dangerous assumption because central bank independence is contingent on political economy conditions that can change.

“I think people uh most bank most central banks weren't I'd say over the last 25 years now most countries do and people just take it for granted been there for 20 years 25 years it will always be independent. That is just nonsense.”

The Plaza Accord of the mid-1980s involved the US and allies forcing Japan to appreciate the yen to reduce US trade deficits, and while the Japanese successfully more than doubled the yen's value within months, this created asset bubbles that led to a financial crisis and lost decade, which Rogoff now views as the US bullying Japan into premature financial liberalization.

“the plaza court happened in the mid80s and Japan was just killing it... we had to, you know, fly back to Tokyo and uh two weeks later they got the message, we're going to make it happen. And they did... Jean Clutch, the former uh head of the European Central Bank, showed me actually the whole agreement, the numbers they picked. They picked that they would appreciate make their currency stronger by 10%. It doubled.”

Trump's stated negotiating approach is that 'what's mine is mine and what's yours we'll talk about,' but this fails to recognize that the US achieves many of its dominant positions in multiple domains (finance, technology, farming) because of the open trading system that created the conditions for that success, so closing off one sector does not preserve advantages in others.

“he seems to he he I I heard him say recently, uh yeah, you know, what kind of a negotiator I am. what's mine is mine and what's yours we'll talk about... we may not have been killing it in manufacturing, but we were in global finance. We were in tech. We were in farming. So, the idea you can sort of cherrypick, well, I'm going to close things off to your manu uh manufacturing, but just keep doing everything else you're doing... That is just dumb.”

Cryptocurrency will not become the dominant global reserve currency, but it does compete in the shadow economy (roughly 20-25% of global GDP) where underground and illicit transactions occur, and crypto provides an alternative to traditional currencies for this segment that regulators cannot easily reach.

“I don't think it will be crypto but I think crypto does compete for the world underground economy which is another favorite topic of mine probably 20 even 25% of global GDP is stuff the author parties don't see.”

The US has legitimate national security concerns about reliance on Chinese manufacturing, particularly in shipbuilding (where China produces 50% of global merchant ships and the US is not even second), and in pharmaceutical production, which are valid arguments for some reshoring; however, these concerns do not justify broad tariffs on agricultural products, wine, and lumber.

“I will say, you know, they're complex national security issues that need to be thought about. For example, the Chinese dominate in ship building. They produce half the world ships and we're not even second or third. And when we want to go build military ships, aircraft carriers, whatever, that's a big problem because there's a big symbiosis between military and civilian uh things. They're many in medicines. We'd like to produce more uh chips.”

Having a dominant currency requires projecting military force; without military dominance, a country cannot sustain a currency used outside its borders, which is why predicted multi-block scenarios (dollar block, euro block, RMB block) underestimated this military requirement.

“you have to be one of the couple dominant military powers. the idea and a whole bunch of authors wrote about this uh brilliant economist but Barry Iiken Green at Berkeley uh a Nobel Class uh economic historian Jeff Frankle uh one of the top international economists many many others predicted 15 years ago that we would go to a situation where there was a euro block a dollar block and an R&B block which is we may go to but uh We didn't. And what was so naive about this is you don't get to have a a currency used outside your area if you don't project military force.”

Had Russia adopted market-oriented reforms similar to China's Deng Xiaoping reforms (such as the Kosygin-Liberman reforms) rather than the path it took, it would have performed substantially better economically and potentially maintained greater geopolitical footprint.

“had Russia adopted reforms like China did, and you're much more expert on this than I am, so I'm embarrassed to talk about it, but you know, like the Kosigan Braznaf reforms that they tried had it had it some flavor of what uh Jing Xiaopen, you know, did in China. Had it made some things market and done a few sensible things, it would have done a lot better.”

Asia comprises 50% of the dollar bloc measured by countries stabilizing exchange rates around the dollar, a metric Rogoff considers a strong proxy for dollar dominance, and China has been moving away from this since 2015.

“Asia's 50% of the the dollar blocked by the measure I use with Ethan [8:20] Ozitki and Carmen Reinhardt. It's not the only one, but I think it's a pretty good one about what countries are trying to stabilize their exchange rate around... Well, China sort of has been moving away from that since 2015.”

Nixon ended the gold standard (Bretton Woods) because the US was running inflation from Vietnam War spending and social program expansion, creating an inconsistency: you cannot fix currency to gold if you have inflation and gold doesn't inflate.

“we were starting to get inflation. And if you want to fix your currency to gold and have inflation, it's not consistent because gold's not inflating. So Nixon at some point said, "Sorry everyone, forget it. You can't trade your dollars for gold."”

Central bank independence was not historically universal; Rogoff wrote the first theoretical paper demonstrating why independent central banks would improve economic outcomes approximately 45 years ago (early 1980s) when most central banks lacked independence.

“I I think I wrote the first paper on why you should have an independent central bank back 45 years ago. The first theoretical paper uh demonstrating why it would be a good idea back back when no one had it.”

Milton Friedman was skeptical of Soviet growth predictions even when they were consensus among economists like Samuelson, and Rogoff was also skeptical, though without access to accurate data on the Soviet economy.

“there were people like Milton Friedman who were skeptical and I was skeptical when I was being taught about this but no we didn't have the data”

American luck in the international system has been extraordinary but has now run out, and the US must rely on skill rather than fortunate circumstances to maintain prosperity.

“And I think Americans don't [31:20] understand how lucky they've been. That, you know, if you go through everything that's happened, I'm not saying the dollar might not have come out on on top, but if you look at how much it came out on top, there was a lot of luck. And I I fear our luck has run out.”

Controlling for the amount of debt the US issues, American 10-year bond interest rates are not lower than rates in other wealthy countries, whereas dollar dominance should produce a 'exorbitant privilege' of lower borrowing costs; this suggests the privilege is already eroding.

“we get a lower interest rate uh for sure controlling for how much debt we issue by the way I mean we issue the United States I'm an American we issue a ton of debt and our interest rate on 10-year bonds actually [10:27] really isn't lower than other countries now controlling for you know various ways of trying to hedge but we have a ton of debt out if we had Germany's debt level our interest rates would be a lot lower”

The US possesses exceptional structural economic advantages: large and arable land base, energy (oil and gas) self-sufficiency despite high consumption, and a culture more accepting of immigrants than peer economies, all of which support long-term economic competitiveness.

“the US has just incredible economic advantages. We do we are actually probably at the moment the world's biggest oil producer and uh way up there in other in other things and that makes us more independent. Uh we have incredible farmland. We have uh incredible um ability to absorb immigrants both in terms of land. I mean [46:28] Japan doesn't they don't have land and also a culture although which is more accepting of immigrants.”

The generational lesson from observing the Soviet Union's collapse (Rogoff was a teenager watching neighbors build bomb shelters during the Cold War) is that systems that seem permanent can change dramatically, making extrapolation of current conditions dangerous.

“Well, but when I was uh you know, when I was a teenager watching my neighbor build a bomb shelter, it didn't seem laughable.”

The US was arrogant in its approach to dollar dominance (as captured in Connally's 'it's our dollar, your problem' statement), and this arrogance is partly justified economically but also partly hubristic and self-defeating.

“what's I like about the title, I've always felt Americans are [17:10] incredibly arrogant. And so I like to point to that. Uh I disagree with some of our policies expressing our arrogance. We'll come to that.”

Rogoff has long argued (over 15 years) that interest rates were low during 2000s-2010s but were historically exceptional, not permanent, contrary to the views of Larry Summers, Paul Krugman, Olivier Blanchard, and many finance ministers who extrapolated low rates as permanent.

“I've long argued that and the the durability of the dollar, it's not going to go away overnight because if you look at long history, they don't go away overnight. But you can lose some of your dominance... the real interest rates as an example where I've been debating that for 15 years saying interest rates were low but if you look historically they weren't always why would you think as Larry Summers Paul Krugman Olivier Blanchard and not to mention many finance ministers politicians they're just going to keep going down”

Military power is a necessary (not sufficient) condition for reserve currency dominance; no currency can be used globally without the issuing country having capacity to project military force and enforce contracts.

“you have to be one of the couple dominant military powers. the idea and a whole bunch of authors wrote about this uh brilliant economist but Barry Iiken Green at Berkeley uh a Nobel Class uh economic historian Jeff Frankle uh one of the top international economists many many [41:11] others predicted 15 years ago that we would go to a situation where there was a euro block a dollar block and an R&B block which is we may go to but uh We didn't. And what was so naive about this is you don't get to have a a currency used outside your area if you don't project military force.”

The 2019 repo market stress episode was misunderstood by many observers; Rogoff, working on Plaza Accord background, learned that currency intervention success depends on obtaining political consensus, which the Japanese achieved by flying back to Tokyo after an initial refusal from the finance minister.

“the Japanese finance minister uh said to me, I can't make this decision myself. And he mentioned, they always have to do things by consensus in Japan. I'm just using his words. So, we had to, you know, fly back to Tokyo and uh two weeks later they got the message, we're going to make it happen. And they did.”

Countries that try to stabilize their exchange rates use a weighted metric that Rogoff co-developed with Ethan Ozitki and Carmen Reinhardt; this metric shows which currency countries choose to anchor to and is a useful measure of global currency dominance.

“the measure I use with Ethan Ozitki and Carmen Reinhardt. It's not the only one, but I think it's a pretty good one about what countries are trying to stabilize their exchange rate around.”
