Overview:

This episode of Business Daily investigates the outsized and sometimes shadowy role of financial bonds in the global economy. Once considered boring and obscure, bonds are now at the heart of economic power and present potential dangers. With stories and historical examples, the episode explores how bonds have shaped nations, economies, and crises, and raises the pressing question: Do bond markets wield too much power, potentially threatening government sovereignty and economic stability?

Key Discussion Points and Insights

1. What is a Bond? (04:01 - 04:20)

• Sarah Quinn: A bond is essentially an IOU issued by governments or corporations to borrow money, promising repayment with interest at maturity. Bond markets are where these debts are bought and sold.

2. Historical Importance of Bonds (04:31 - 05:27)

• Sarah Quinn: It’s "hard to understate” the role of bonds in economic development. Without debt markets, economic growth would be much slower; bonds finance everything from railroads to schools, enabling risky but transformative investments.

3. The Origins of Bonds (05:34 - 06:17)

• Kenneth Rogoff: The earliest government bonds were likely issued by Italian city-states in the 12th century, with private company bond issuance coming later, notably with the Dutch East India Company in the 1600s.

4. A Living Piece of History: The Dutch Water Bond (06:17 - 10:17)

• Rob Young & Geert Roanhorst:
  • In 1648, a Dutch water authority issued a bond (on goatskin vellum) to finance levees. This bond, now owned by Yale University, still pays annual interest nearly 400 years later.
  • Notable Moment:
    • Geert Roanhorst: "This could live for another thousand years, no problem." (10:11)
    • The bond pays €11.35 per year—much less than the cost of collecting it!
  • Memorable Quote:
    • "The organization that issued it is a water board or water authority. Their objective was to help defend the country against the water..." (08:09)

5. Bonds and Warfare (11:29 - 13:55)

• Sarah Quinn: Wars are expensive, and taxation is slow and unpopular, so states with good credit could quickly raise funds for armies by issuing bonds.
• Kenneth Rogoff: England’s repeated wars and eventual financial default in the 1300s led to innovations like the Bank of England, allowing for vast borrowing capacity — the “secret sauce” behind many British victories.
  • Quote:
    • "The ability to borrow was the secret sauce." (13:55)

6. Modern Bond Markets and Recent History (13:55 - 15:25)

• Bonds have exploded in size, especially post-WWII, due to crises like the global financial crisis and the COVID pandemic.
• The bond market is now larger than the stock market.
• Kenneth Rogoff: Borrowing is at record peacetime highs, partly to meet social promises like pensions and healthcare. Markets still lend, but increasingly demand higher interest.
  • Quote:
    • "Government borrowing in many countries is hitting peaks only seen in wartime." (14:15)

7. Bond Market Evolution and Complexity (15:25 - 16:53)

• Sarah Quinn: Post-Great Depression regulation made bonds boring, but deregulation from the 1960s onwards saw innovation and complexity (e.g., mortgage-backed securities, CDOs), culminating in the 2008 financial crisis when the true risks in bond pools were misunderstood.
  • Quote:
    • "They can get so complex that nobody really knows what risks are in the pool. That level of complexity was absolutely crucial to the lending boom and bust that led to the great financial crisis in 2008." (16:32)

8. The Political Power of Bond Markets (16:53 - 17:50)

• Bond markets have outgrown stock markets in power and influence.
• Bond investors can "discipline" governments by making it expensive or even impossible to borrow if they disapprove of fiscal policies.
• Sarah Quinn: “Bond markets can discipline governments, making it expensive or impossible for them to borrow...” (17:41)

9. When Finance Trumps Democracy (17:50 - 19:20)

• Kenneth Rogoff:
  • "That’s been true forever for emerging markets" — bond markets have long been more powerful than electorates. Defaults were common in Europe’s history.
  • In developed countries today, the risk is not default but inflation — governments may print money to ease debt burdens, which leads to rising prices.
  • Notable Quote:
    • “It’s something where governments need to make adjustments, but probably won’t until there’s some kind of fiscal crisis.” (18:53)

Useful for Listeners Who Haven’t Tuned In:

This episode paints bonds not as dull background operators, but as active shapers of nations, economies, and political outcomes—sometimes heroically, sometimes with potentially villainous power. Bonds have funded everything from medieval levees to modern wars, shaped the outcome of empires, catalyzed financial crises, and now hold influence over governments that can rival, or even eclipse, democratic accountability. As the episode concludes, the discussion sets up the next: are bond markets now so powerful they pose a risk to democracy and fiscal stability?

[Rob Young]

When I was asked to make a program about bonds, I leapt at the chance. After all, I'm a huge fan of James Bond, the suave British spy who repeatedly saves the world. But I was wrong. These aren't the bonds with tuxedos and martinis. These are financial bonds, silent operators in the global economy. And like their fictional namesake, they've worked in the shadows, rarely noticed yet shaping the fate of nations. They've even played roles in wars and crises and but here's the twist. Today, some economists see bonds not as heroes, but as villains, dangerous, capable of detonating the world economy. In this edition of Business Daily with me, Rob Young, we'll explore how the world became so dependent on bonds it's.

[Sarah Quinn]

Hard to understate their importance. It's really, really important for the economy.

[Rob Young]

You'll hear how bonds have shaped companies and countries and why some fear they could trigger the next global meltdown.

[Kenneth Rogoff]

I think it's something where governments need to make adjustments, but probably won't until there's some kind of fiscal crisis.

[Rob Young]

That's Business Daily from the BBC. Author Ian Fleming once said that James Bond was the dullest name he could think of, and the word Bond has carried that same reputation for centuries, bond markets have never dazzled the public like their glitzier cousin, the ST market. But don't be fooled. Bonds have been powerful for hundreds of years, even in Shakespeare's time.

[Shakespeare / Historical Voice]

I'll have my bond. Speak not against my bond. I have sworn an oath that I will have my bond. I pray you, hear me speak. I'll have my bond. I will not hear you speak. I'll have my bond. Therefore speak no more.

[Rob Young]

That scene from the Merchant of Venice, written in the 16th century. And by then, bond had already been around for 500 years. Bonds, dull, serious, sober, uninteresting for centuries. But now they are at the center of a global debate. Do bond investors have just too much power over governments? Over the next two programmes, we'll dig into that question, starting today with the backstory, how did we get here and what does it mean for the future? And to finance experts will help us unravel the plot.

[Sarah Quinn]

I'm Sarah Quinn, I'm associate professor of sociology at the University of Washington.

[Kenneth Rogoff]

I'm Kenneth Rogoff, I'm a professor of economics at Harvard University.

[Rob Young]

Let's get an explanation. What exactly is a bond?

[Sarah Quinn]

So a bond is an IOU that's issued by governments or corporations they use to borrow money and they'll pay an amount, a principal, over time. That amount of time is talked about as maturity, and they'll pay it with interest. So bond markets are where investors buy and sell those debts.

[Rob Young]

So how crucial have bonds been, then? How crucial has bond issuance been? When we look at the development of economies, of the global economy throughout history.

[Sarah Quinn]

It'S hard to understate their importance because you have to imagine, if any time anyone wanted to start a business, they had to save up all the money to do it themselves. So, you know, farmers and traders and industrialists and inventors and entrepreneurs, they all rely on borrowing to get businesses started. And an economy without debt would move incredibly slowly. So railroads and skyscrapers and factories, these are all things that rely on debt financing. And it matters for the government too. It's not just about private firms. Governments use bonds to borrow and they invest that money in building power grids in schools and education that informs the workforce. Governments are often involved in making really risky investments that can have big breakthroughs in economies over time. So it's really, really important for the economy.

[Rob Young]

Ken, take us back to the beginning of bonds, then. Do we know when the first bond was issued?

[Kenneth Rogoff]

The first government bonds were probably issued by Italian city states in the 12th century. Genoa, Venice, Florence. The early bonds Would be the duke or the king says, give me some money this time I'm going to pay you back. He doesn't necessarily say when or how, and presumably did that to coax more money more quickly out of people. The first private companies to issue bonds were much, much later, usually thought to be the Dutch East India Company. That was in the Netherlands. They started issuing bonds in the 1600s, and then markets gradually came to other countries later.

[Rob Young]

That mention of the Netherlands is a great opportunity to talk about a piece of living bond history. From there, let me take you back to 1648. A water company in the famously wet Netherlands needs cash to build a levee. It doesn't raise taxes. It borrows money by issuing bonds. The IOU isn't written on paper, but on vellum goatskin. Almost four centuries on, one of those original bonds survives, and it's still collecting interest. The bondholder is Yale University in the United States. Hi, Geert. How are you doing?

[Geert Roanhorst]

Very well, thank you.

[Rob Young]

Geert Roanhorst, a Dutch professor of finance at Yale, showed me his prized possession over a video link.

[Geert Roanhorst]

Is there a. Can you. Can you press the button?

[Rob Young]

It's history you can hold in your hands and proof that bonds aren't just about money. They contain stories that stretch across centuries.

[Geert Roanhorst]

It's a manuscript bond, which means it's sort of written on vellum, actually, at that time. And what's unusual about this bond is that it still pays interest.

[Rob Young]

Can you read what it says? The writing looks incredibly old.

[Geert Roanhorst]

It is old, and if you just looked at it first, it just looks like an old manuscript. Although I'm Dutch myself, it wouldn't occur to me at a first look that this is actually a Dutch bond. The language itself was quite different from the way we sort of write and construct sentences today. So it is actually hard to read. When we acquired the bond, I actually contacted somebody with the knowledge of medieval Dutch to kind of decipher what the bond was really about. It's an obligation to pay interest over the equivalent of 1,000 Carolus guilders, which was the currency in the mid 17th century in the Netherlands.

[Rob Young]

And what was the original loan for? Why were these bonds issued?

[Geert Roanhorst]

The organization that issued it is a water board or water authority. Their objective was to help defend the country against the water. You know, if there weren't any system of levees in the Netherlands, half of it would be, you know, underwater and a big floodplain. So these water authorities were these semi, you know, governmental organizations that were set up to kind of organize people to join forces to combat the waters.

[Rob Young]

And so you are still collecting interest on this almost 400 years after it was first issued. Which is incredible, isn't it, given that presumably most bonds aren't around for anything near that length of time.

[Geert Roanhorst]

So there's a number of reasons why it's incredible. The first is that the instrument has survived. If we would have lost this bond, the physical document, there'd be nothing to present to collect the interest. So in some sense that's a miracle. The second thing is that many of the perpetual bonds that were issued had call provisions, which means that the issuer could at some point raise their hand and says, you know, enough already. I'm going to just repay my obligations. Although they were issuing perpetuity, I have the right to basically, you know, repay these bonds early, but this one is actually, is not callable. That's unusual about this.

[Rob Young]

So your university then will continue to be entitled to annual interest payments for forever, Forever.

[Geert Roanhorst]

Now it's not going to be, you know, a huge amount. As we said it was 50 corollish gulers. Of course, Corollish guilders don't exist anymore. We collect the equivalent of about, you know, €11. And I have it here in front of me. It's €11 and 35 cents on this bond, about $13. So every so many years we collect annual interest on this bond.

[Rob Young]

I imagine the flight costs considerably more than the interest payment you collected.

[Geert Roanhorst]

I was actually visiting family, so it kind of all worked out.

[Rob Young]

And how long do you think you'll be able to store it for before it disintegrates in some way?

[Geert Roanhorst]

Vellum is just incredibly sturdy. This could live for another thousand years, no problem.

[Rob Young]

We're investigating the rise of financial bonds and asking over two programmes whether bond markets have too much power today. With the help of Professor Ken Rogoff from Harvard University and Professor Sarah Quinn from the University of Washington, governments first entered the bond game for survival, to defend against wars and to start them. Those decisions changed the course of history.

[Shakespeare / Historical Voice]

If we are to win this war, every penny that can be spared must go into war savings, stamps and bonds.

[Rob Young]

This is a US treasury video from during the Second World War, an attempt at persuading people to lend their money to the government to fight Germany and Japan. Buy United States war bonds and stamps.

[Sarah Quinn]

Sarah War is expensive. Armies are expensive, Provisions are expensive, Weapons are expensive. If you're talking about the Middle Ages, defensive walls, fortifications, all of these things are very expensive. And you might think that states or city states, governments just rely on taxation. But taxation can be really slow, especially historically. It's hard to gather, it takes time and it can meet a lot of resistance. Countries or city states with really good reputation, with good credit, are able to move very quickly to form and mobilize resources to hire mercenaries to build up their military capacity, which is a huge advantage to win wars.

[Kenneth Rogoff]

Ken we usually think of the first sovereign debt crisis when a country defaulted as England in the 1340, when the king borrowed money for yet another invasion of France. It didn't work out. The money was from Italian lenders. They're the ones who had perfected this instrument and that was sort of the first big default. And actually England had a lot of problems with this for a while until the Glorious revolution in the 1680s developed the bank of England, which turns out to be transformative because the bank of England sort of took charge of paying back the debt. And a lot of people say that the reason the UK was able to defeat the much more populous French time after time was this incredible ability to borrow. So in some ways, the ability to borrow was the secret sauce.

[Rob Young]

Well, governments may have borrowed a lot during wartime, but they've taken on more and more debt, issued more and more bonds in peacetime, partly to deal with the shocks of the global financial crisis and, and the COVID pandemic. The previously quiet, dull bond market is now bigger than the much more Talked about and glitzier stock market.

[Kenneth Rogoff]

Government borrowing in many countries is hitting peaks only seen in wartime. And even then, that doesn't fully state how difficult it is to balance the books. Because until really the last few decades, we didn't have old age pensions, we didn't have old age care, anything like today. And old age care is a lot lighter debt because young people are paying taxes, old people are getting the benefits. It's a promise. It's a political promise, but it's a pretty powerful one. So certainly the big borrowers right now are governments. And so far, the markets are happy to lend to them, but the interest rates have been going up and up in recent years. So the markets are happy to lend to them, but they want to get paid more and more.

[Rob Young]

Almost anything, it seems, can be sold through bonds. The singer David Bowie sold off the rights to royalties for his music in an innovative bond sale in 1997. So from water levees to wars to rock legends, bonds have evolved into something far more complex compared to their simple beginnings. It's something Sarah has written a book on.

[Sarah Quinn]

For much of the period after World War II, bond markets were very simple, very stable, very boring markets. And this is because they were highly, highly regulated after the Great Depression. So it was in the 1960s that we start to see real waves of deregulation and also in the government, encouraging using more complex methods for lending. The core of the complexity is the ability to take a bunch of different loans and put them in a pool. So if you're lending to any one given person and that person goes bankrupt, you've lost all your money. But we can use the law of large numbers to put many different loans in a pool, and then your odds of losing all your money if one defaults is much lower. And over time, with computer technology, they developed very, very sophisticated ways of slicing and dicing these to divide up risks, to organize financial flows in ways that would really appeal to investors. The problem is they get so complex. So you can get pools based on pools based on other pools. They can get so complex that nobody really knows what risks are in the pool. That level of complexity was absolutely crucial to the lending boom and bust that led to the great financial crisis in 2008. There was just so much risk in these pools and people didn't understand really what they were.

[Rob Young]

And so they've got incredibly complex, too.

[Sarah Quinn]

Powerful bond markets are bigger than stock markets. They're massive. This is not inevitable. This was not always the case in society after World War II. It's really big corporations that are the most powerful force in the economy, they're the center of profit making, they're the center of political influence. But following all the deregulation that happened in the 70s and 80s and the rise of these markets, it's really finance. Bond markets are a huge part of it that are the center of power and profit in the economy. Having that much power and that much profit brings a great deal of political influence. Governments rely on bond markets to borrow. So bond markets can discipline governments, making it expensive or impossible for them to borrow if they don't like how the government's ruling or if they don't trust that that government is going to really be willing to tax the population at a level that will repay the debt.

[Rob Young]

Ken, you're a former chief economist at the International Monetary Fund and kept an eye on many nations finances. When did it become clear to you that the bond markets were in some cases more powerful than electorates?

[Kenneth Rogoff]

Well, that's been true forever for emerging markets. And if you go back to advanced economies when they were emerging markets, England defaulting in the 1300s, 1400s, even into the 1500s, Spain defaulted 13 times in its history. France has defaulted eight times. Everyone's gone through this period of development where the bond market would eventually call the government's bluff. In advanced countries, that's less of an issue today because we don't back the currency with gold and the problem is more inflation. Governments will inflate their way out of a difficult situation. And it's probably going to happen sometime over the next four or five years, more likely than not in the U.S. possibly the UK, possibly France, where interest rates move up. Now, they're not going to be like Argentina or Greece where just no one will lend money because they can afford to print money. But on the other hand, if you print a lot of it, we've seen that movie many times. Quite recently after the pandemic, you get prices going up and up. So I think it's something where governments need to make adjustments, but probably won't until there's some kind of fiscal crisis.

[Rob Young]

And tomorrow Ed Butler will tackle that. Big question, is the bond market, which some argue is too powerful, pushing some governments towards a crisis point? My thanks to Professor Ken Rogoff from Harvard University and Professor Sarah Quinn from the University of Washington for their Insight sites. And thanks to you for listening to this edition of Business Daily.
