Summary

Planet Money: "How Hurricanes Became a Hot Investment"

NPR | December 5, 2025
Hosts: Jeff Guo, Waylon Wong

Episode Overview

This episode dives into the unexpected world where natural disasters—specifically hurricanes—become investment opportunities through the creation and sale of catastrophe bonds (cat bonds). Using Jamaica’s experience with recent devastating hurricanes as a jumping-off point, the hosts trace the origins, mechanics, and rapid growth of these exotic financial instruments. The conversation features how cat bonds are reshaping the insurance industry, benefiting countries at risk, appealing to investors, and even funding disaster relief for global pandemics.

Key Discussion Points & Insights

1. Jamaica’s Big Financial Bet

• [01:52] Fayval Williams, Jamaica's Minister of Finance, visits hurricane-devastated communities.
• Jamaica made an "actual bet" on hurricanes with catastrophe bonds, ensuring funds are available for rebuilding after disasters.
• Fayval Williams: “We are in the belt, the hurricane belt. There isn’t much we can do to change that. But what we can do is to take the steps to ensure that we have access to financing.” ([03:22])

---

2. Catastrophe Bonds Explained

• [03:58–04:56] The basic mechanics: The country (or insurer) sells bonds to investors. If no disaster strikes, the investors get their money back plus interest. If disaster strikes, the government keeps the money to use for rebuilding.
• Cat bonds shift risk away from insurers to international investors.

---

3. Origins of the Cat Bond Market

• [06:31–13:27]
  • Karen Clark, a trailblazer in catastrophe modeling, pioneered computer simulations that could predict the cost of disasters.
  • Her models revolutionized the insurance industry, which previously relied on guesswork for reinsurance.
  • The turning point: Hurricane Andrew (1992). Clark’s model predicted losses over $13 billion when the industry expected just $5–7 billion. The actual loss: $15 billion.
  • Karen Clark: “There was not much science underlying those decisions. … Really rule of thumb.” ([09:33])
  • Karen Clark: “That was the turning point. And then the whole industry became believers in the model.” ([13:03])

---

4. The Rise & Appeal of Cat Bonds for Investors

• [13:42–20:56]
  • Post-Hurricane Andrew, there was a shortage and soaring price of reinsurance.
  • Insurance companies worked directly with investors—bypassing reinsurers—to issue cat bonds.
  • Ethan Powell, an early investor: “Maybe instead of having all chicken eggs. You have one ostrich egg…harder and not breaking in the event that the basket falls.” ([17:34])
  • Cat bonds offer:
    • Diversification, since disaster risk isn’t correlated with financial markets.
    • Higher yields than similarly rated corporate bonds—“2 to 3% more on the yield relative to the corporate rating.” ([19:05], Ethan Powell)
    • Social benefit: “Your capital is playing a role in society.” ([20:56], Ethan Powell)
  • The cat bond market is now worth about $60 billion and is mainstream among pension funds.

---

5. Cat Bonds Beyond Hurricanes: Pandemic Bonds and More

• [22:47–27:06]
  • Cat bonds have expanded to cover terrorism, cyber attacks, and even pandemics.
  • Michael Bennett, World Bank, spearheaded pandemic bonds to address Ebola risks and, incidentally, COVID-19.
  • Michael Bennett: “People thought, this is an extremely innovative way to use the cat bond market. No one had ever done it before.” ([25:52])
  • The World Bank’s pandemic bond triggered in 2020, funneling hundreds of millions to poor countries for COVID-19 relief.

---

6. How Cat Bonds Actually Play Out: Jamaica’s Experience

• [27:24–31:19]
  • Jamaica worked with the World Bank to issue its first cat bonds in 2021.
  • Payout conditions are very specific (e.g., storm’s air pressure in precise grid location); not every major storm qualifies.
  • After Hurricane Beryl caused nearly $1B in damage, the bond didn’t trigger, prompting public debate.
  • Fayval Williams: "Just because it didn’t trigger is no reason not to continue to have it. It’s an insurance policy." ([29:50])
  • When extremely severe Hurricane Melissa hit, the cat bond did trigger, providing $150M instantly for rebuilding.
  • Fayval Williams: “Everybody was talking about it…who never knew about a cat bond knew about it.” ([30:55])
  • Fayval Williams: “Behind the dollars are people, real people with lives, who would not have anything else to help them.” ([31:19])

---

7. The Bigger Economic Picture

• [31:46–end]
  • As cat bonds become more mainstream, they create more competition, potentially lowering the cost of reinsurance and thus insurance for everyone.
  • The evolving cat bond market may be vital as climate risks increase: “As the weather gets more and more chaotic…it's maybe not a bad idea to find more and more ways to share that risk.” ([32:17], Jeff Guo)

---

Notable Quotes & Memorable Moments

• Karen Clark’s dry humor on her early career:
  “But I do like to remind people I was a child prodigy and started when I was 10. Just so you can. That’s a joke, by the way, Jeff.” ([07:19])

• The skepticism Clark encountered in London:
  “I was a woman coming in, an American woman, and I was seven months pregnant at this time... lugging this 35-pound portable computer.” ([10:42])

• Investor Motivation:
  Ethan Powell: “Cat bond is the lion king of them all… sitting on top of the mountain.” ([18:33])

• World Bank’s carpet commentary:
  Michael Bennett: “At the World Bank…the goal is not to make money. It is to fight poverty.” ([24:11])

• Jamaica’s Min. of Finance on real-world impact:
  “Behind the dollars are people, real people with lives, who would not have anything else to help them.” ([31:19])

[Jeff Guo]

A few weeks ago, Fayval Williams drove across Jamaica to the west side of the island to see the damage with her own eyes. She was headed to where the worst hurricane in her country's history had made landfall.

[Planet Money Narrator]

When she got there, there was a lady and she says, come with me, let me show you. This is where my house used to be.

And you go where it's like right here. There was nothing in the space. It was all gone.

You saw persons just sitting and looking off into the distance wondering what's next for Fayval.

[Waylon Wong]

For all Jamaicans, this is unfortunately a familiar scene. After hurricanes, only Hurricane Melissa was worse. It was a category 5 winds of 185 miles per hour. And now people were adding up what they had lost, trying to figure out how they would get it back.

[Planet Money Narrator]

I found myself just hugging people, assuring them that the government would take steps to help them to rebuild.

[Jeff Guo]

And Faywal, she is the government. She's actually Jamaica's minister of finance. So she knew that Jamaica had been preparing for exactly this kind of catastrophe, preparing so that the country could pay to rebuild the roads, to rebuild people's homes. And to do that, Jamaica had some financial tricks up its sleeve.

[Planet Money Narrator]

We are in the belt, the hurricane belt. There isn't much we can do to change that. But what we can do is to take the steps to ensure that we have access to financing.

[Waylon Wong]

In particular, she was thinking about this one kind of unusual financial maneuver that Jamaica was experimenting with. It was a wager.

[Jeff Guo]

Yeah. The country of Jamaica had made a big bet, an actual bet, on hurricanes.

Hello and welcome to Planet Money. I'm Jeff Guo.

[Waylon Wong]

And I'm Waylon Wong. A few years ago, the Jamaican government went all around the world saying to investors, we bet we're gonna have a pretty big hurricane in the next couple years. You wanna take the other side of that bet? Basically, if there's no hurricane, you investors get your money back and more. But if there is a hurricane, a big enough hurricane, the Jamaican government gets to keep your money and use it to pay for rebuilding.

[Jeff Guo]

This kind of financial wager is called a catastrophe bond. And the market for catastrophe has gotten really hot lately. Today on the show, the story of where catastrophe bonds come from, why they've gotten so popular, and how they are changing the way insurance works for Jamaica and for all of us.

To learn all the advantages and connect with a dedicated Business advisor Catastrophe bonds are like the ultimate form of insurance, because if you think about it, that's what insurance is. It's a bet involving potentially bad outcomes, whether that's a car crash or a house burning down or a Category 5 hurricane.

[Jeff Guo]

But with catastrophe bonds, instead of an insurance company making the payout when things go south and it's investors, people making bets against an earthquake hitting Japan or a wildfire sweeping through California.

[Waylon Wong]

And the story of how betting on natural disasters became a market, a big thriving market, really starts with this one person.

[Karen Clark]

My name is Karen Clark.

[Waylon Wong]

People have actually called Karen an icon.

[Jeff Guo]

Do you accept that title?

[Karen Clark]

I guess so.

[Jeff Guo]

Karen is this computer stats whiz. She specializes in the math of catastrophes. Her job is to calculate the risk of extreme and rare disasters. She was one of the first to predict how much damage they might cause and how much the rebuilding would cost.

[Karen Clark]

I've been doing it for a long time, since 1987. But I do like to remind people I was a child prodigy and started when I was 10. Just so you can. That's a joke, by the way, Jeff.

[Jeff Guo]

I believed it.

[Waylon Wong]

Okay, so Karen might not have been a child genius, but she was way ahead of her time. In grad school, when she was what, 12, she studied how to run simulations on these cutting edge machines that people were calling computers. That landed her a job at an insurance company where her bosses asked her to apply her skills to the problem of hurricanes.

[Jeff Guo]

You see, for insurance companies, hurricanes are a special headache. Standard insurance works great for covering your typical day to day risks, like if a pipe bursts and floods the basement. Insurance companies can handle all that. What's much harder for them to handle are the big, once in a generation catastrophes. Like when a Category 5 hurricane tears through a city and suddenly everybody needs to rebuild their homes. A disaster like that can overwhelm a.

[Waylon Wong]

Single insurance company, which is why your insurance company will actually buy insurance for itself. Insurance for insurance companies is called reinsurance. Most insurance companies will take out reinsurance policies to protect them in case of natural disasters like earthquakes or hurricanes.

[Jeff Guo]

Why is it called reinsurance?

[Karen Clark]

That I can't answer that.

[Jeff Guo]

Why is it not like insurance squared?

[Karen Clark]

Well, it's even more complicated because there are actually entities called retrocessionnaires that reinsurers also reinsure.

[Waylon Wong]

Okay, so back in the 1980s, while she was working for that insurance company, Carrie was looking into this complicated system of insurance and reinsurance and re reinsurance. And she realized that when it came to catastrophes like hurricanes, the whole market was still Mostly operating based on guesswork.

[Jeff Guo]

The insurance companies weren't really sure how much hurricane insurance they actually needed to buy from the reinsurers and the reinsurance companies. They weren't really sure how much to charge for that hurricane insurance.

[Karen Clark]

There was not much science underlying those decisions. There was not much analysis. This is where it was really rule of thumb.

[Waylon Wong]

But Karen's like, no, no, no. There's actually a smarter way to do this. We can use computers to simulate thousands of different disaster scenarios, Plug in data about things like how homes in an area are built and how much they'll cost to repair. That'll give us a much clearer picture of the actual risks here. And Karen is so convinced of this that she soon starts her own one person company to build and license these computer models to the insurance industry.

[Jeff Guo]

Now, at the time, a lot of hurricane reinsurance came from this one place. It's called Lloyd's of London. And the folks at Lloyd's, they're kind of famous for selling, you know, unusual kinds of insurance. Like, they're the ones who insured Bruce Springsteen's voice and also David Beckham's legs.

[Waylon Wong]

And Karen gets this huge opportunity. She gets a meeting with them to show off her hurricane model. So she makes the pilgrimage to their London headquarters. She flies across the pond, lugging her newfangled portable computer along with her.

[Karen Clark]

Then a portable computer weighed like 35 pounds or something. You know, carting this thing in, putting it up. I had maybe 100 British men sitting in the audience that had never seen one of these before. Not only that, you haven't heard anything yet. I was a woman coming in, an American woman, and I was seven months pregnant at point this time.

[Jeff Guo]

No.

[Karen Clark]

Yes. And so I waddled in, pulling this computer, and started showing them how they were gonna do better by using this little computer model.

[Waylon Wong]

The men at Lloyd's, they are skeptical.

[Karen Clark]

They were polite, you know, but there wasn't really any discussion. Maybe some were falling asleep, but the room was dead. Well, you know, I'm pretty thick skinned, so I was like. At least most of them were still awake at the end.

[Jeff Guo]

One problem was that Karen's models, they were saying something scary. That the whole industry was vastly underestimating the risk of hurricanes. So it wasn't just the folks at Lloyd's who were skeptical.

[Waylon Wong]

A lot of people were, until something happened that grabbed everyone's attention.

[Karen Clark]

The year was 1992.

[Waylon Wong]

In 1992, Karen and her team were tracking this hurricane that had suddenly gotten very strong, very fast. It was a category 5, 160 mile per hour winds. The name was Hurricane Andrew and it was headed for Miami.

[Karen Clark]

So Andrew made landfall at 5am on Monday morning. And we're running the model to see what the losses could be. And we're getting these big numbers.

[Jeff Guo]

Karen's company had a handful of clients at the time who were paying her to predict how much damage this was all going to cause.

[Karen Clark]

And I was a little nervous about it. But we faxed out to our clients at 9am that the losses could exceed the 13 billion. And the phone started ringing. No one believed it. And again, we're, this is British. They're like, I'll bet you 5 quit it won't be more than 5 billion.

[Jeff Guo]

Karen says everybody in the industry, they were predicting, at worst, this is a $7 billion hurricane, but not 13 billion. No way.

[Karen Clark]

Six months later, the industry has tabulated the losses. It was 15 billion.

[Jeff Guo]

That's right. In the end, Karen's model was pretty close to the mark.

[Karen Clark]

That was the turning point. And then the whole industry became believers in the model. I would say. Six months after Hurricane Andrew, did you.

[Jeff Guo]

Get any, like, apology faxes saying, like, sorry we doubted you?

[Karen Clark]

No. But more than that, we got a lot of signups that was better than apology.

[Jeff Guo]

A lot more customers.

[Karen Clark]

Exactly.

[Waylon Wong]

And now that the whole industry was paying attention to Karen's models, insurance companies realized, holy cow, we have not been buying enough insurance for our insurance. If hurricanes are going to be this bad, we're going to need a lot more reinsurance.

[Jeff Guo]

And at the same time, the reinsurers, like the folks at Lloyd's, they were realizing, oh, no, this hurricane reinsurance is actually a really dangerous market to be in.

[Karen Clark]

You know, holy cow. And probably they weren't thinking cow. We've really been underestimating this risk and we need to charge a lot more for it. So the price for reinsurance went through the roof.

[Jeff Guo]

But even with those higher prices, there still wasn't enough reinsurance to go around. By the late 90s, the whole insurance industry was facing this shortage of reinsurance.

[Waylon Wong]

This is when the insurance companies get an idea. They're like, if we can't get enough reinsurance from Lloyd's of London, maybe we could also go around them, you know, go straight to Wall Street. There's a whole world of investors out there. Maybe some of them might want to get in on this catastrophe reinsurance game.

[Jeff Guo]

And this, this is the defining moment, not just for Karen, but for the whole insurance industry. Because this is the moment when the catastrophe bond is born. A catastrophe bond is basically a way for insurance companies to sidestep the reinsurance industry, to get reinsurance not from reinsurance companies, but from a much broader pool of people, from investors.

[Karen Clark]

It really was an amazing innovation and it was very exciting. I will say for me personally, you know, it couldn't have happened without, you know, my model.

[Jeff Guo]

And here we should take a minute to explain how these catastrophe bonds or cat bonds actually work from the point of view of the investors. Basically, it's like making a loan to the insurance company. Investors might put up $200 million and the insurance company hangs onto that money for a couple years and in the meantime pays the investors a bunch of interest. Then after a couple years, the investors get their original $200 million back plus all of that interest.

[Waylon Wong]

That is, unless a big enough hurricane strikes sometime during those couple of years. It in that case, the investors don't get their money back. The insurance company gets to keep that $200 million and use it to cover people who are rebuilding their houses.

[Jeff Guo]

So with cat bonds, the investors are taking on a major risk. They could lose all their money with one big catastrophe. This is where Karen's models come in. Her models made this market for cat bonds possible because they could show investors exactly what risks they were taking on.

[Karen Clark]

I had to fly all around the world, Tokyo, Frankfurt, London again, and be sitting in these smoke filled rooms to explain to investors how the models work and convincing them that they wanted to invest in these cat bonds.

[Waylon Wong]

For a long time, not that many investors were interested in catastrophe bonds because even if you believed Karen's models, you were still literally betting on hurricanes and natural disasters. These risks were a little too exotic for most of the starched shirts on Wall Street.

[Jeff Guo]

But for some investors, the weirdness of cat bonds, that was kind of their appeal. Back in the 2000s, Ethan Powell was a manager at a multibillion dollar investment firm based in Dallas, Texas.

[Ethan Powell]

You know, Texas is the wild west, so we were always a little bit on the on the cusp of what we were willing to invest in.

[Waylon Wong]

And Ethan's firms specialize in what are called alternative investments, like buying out people's life insurance policies or betting on the future sales of some life sa. And they were also early investors in catastrophe bonds, bought millions of dollars worth of them.

[Jeff Guo]

And there's one big reason why investors like Ethan chase these kinds of alternative investments. In fact, it's a very traditional reason. The goal is diversification. You know, don't put all your eggs into one basket. Actually, Ethan, of course, has this alternative metaphor.

[Ethan Powell]

Maybe instead of having all chicken eggs. You have one ostrich egg, and it ends up being harder and not breaking in the event that the basket falls right.

[Waylon Wong]

For some people, diversification might mean, okay, instead of putting all of our savings into Apple stock, maybe we'll buy some IBM stock or McDonald's stock. Maybe we'll buy a little piece of every company in the S&P 500.

[Jeff Guo]

But Ethan is like, well, what if there's a recession? All those stocks might go down all at the same time. So for Ethan, a really good alternative investment is something that is so unrelated to the rest of the economy, where even if the entire stock market crashes, at least your alternative investments are doing okay.

[Waylon Wong]

This is why some people really like catastrophe bonds, because they tend to be so uncorrelated with your other investments. You know, the profits or losses at Microsoft and McDonald's have very little to do with chances that, say, a typhoon will or won't hit the Philippines next year.

[Ethan Powell]

In a world of interesting alternatives, it is my belief cat bond is the lion king of them. All right. Like it is. It is sitting on top of the mountain.

[Jeff Guo]

Yeah, the cat bond stands alone. So diversification, you know, is one reason why investors like Ethan put money into cat bonds. But another big reason is that cat bonds are also kind of lucrative.

[Waylon Wong]

And Ethan says when you put cat bonds side by side with corporate bonds that are similarly risky, some cat bonds will pay you a lot more interest.

[Ethan Powell]

Between 2 and 3% more on the yield relative to the corporate rating.

[Jeff Guo]

So in finance terms, 2 to 3%. That's a lot. Yeah.

[Ethan Powell]

For a fixed income instrument, it is.

[Waylon Wong]

When Ethan first got into cat bonds in the 2000s, the market was tiny. Over the past couple years, they have exploded into an almost $60 billion market, and one that is still growing exponentially.

[Jeff Guo]

For investors, cat bonds are kind of becoming mainstream. You're seeing huge public pension systems buying them up. Which means the interest from cat bonds is helping to fund the retirement of, like, schoolteachers in Arkansas and public employees in Virginia.

[Waylon Wong]

At the same time, more and more insurance companies are turning to cat bonds to solve one of their big problems right now, which is climate change. The research says that hurricanes are getting more intense, Wildfires are becoming more frequent in high risk places like California and Florida. A lot of insurance companies are pulling out. They're like, this is too much risk for us.

[Jeff Guo]

So right now in Florida, for instance, hundreds of thousands of people can only get their home insurance through the state. Florida runs this nonprofit insurance company called citizens that insures some of the Riskiest homes in Florida because they have to. And while citizens used to buy a lot of traditional hurricane reinsurance from places like Lloyd's, now it gets most of its hurricane coverage through cat bonds because they can get a better deal from investors.

[Waylon Wong]

And so investors like Ethan are helping citizens provide insurance to people living in risky areas. Ethan's firm owns some of those cat bonds from citizens. The latest ones pay investors between 8 and 13% interest. And he knows that if a big hurricane hits Florida, he's going to lose his investment. And he kind of likes that part.

[Ethan Powell]

Your financial outcome is tied to hurricanes and natural disasters, but your capital is playing a role in society. This is the role, right?

[Jeff Guo]

Ethan says at least what money he loses on cat bonds will go toward rebuilding people's homes. Cat bonds actually have this kind of do goodery reputation in the finance world. And it almost sounds too good to be true. Right? Like cat bond investors are supposedly making these big profits, but also they are helping people rebuild in the wake of a catastrophe.

[Waylon Wong]

After the break, we talked to someone who tried to take the idea one step further, who thought, what if cat bonds could help people suffering from Ebola?

[Jeff Guo]

Com.

Here at Planet Money. There's a thing that we like to say, okay, that I like to say, which is that humanity's greatest invention is insurance. Think about it. Insurance is basically a technology to transfer risk from one person to another, from one place to another, from me to my insurance company, from my insurance company to a reinsurance company. Catastrophe bonds are kind of the next evolution of that. They let insurance companies take some of the risks they're facing, the risk of a giant hurricane or earthquake, and transfer those Risks onto a crowd of investors around the world.

[Waylon Wong]

And we're starting to see more and more unusual types of risk getting packaged and put onto the market, like cat bonds for terrorism risk or cyber attacks.

[Michael Bennett]

I think probably the most complex I've ever worked on was our pandemic transaction.

[Jeff Guo]

Yeah. I mean, why not even a cat bond for a worldwide pandemic? Michael Bennett works on these kinds of creative financial ide at the World Bank. There's actually a fancy Wall street term for getting creative. It's called structured finance. And Michael actually got his start at a bunch of those fancy Wall street firms.

[Michael Bennett]

Very thick carpets. You'd walk down, and you wouldn't hear yourself at all.

[Jeff Guo]

How thick are the carpets at the World Bank?

[Michael Bennett]

Yeah, no carpets. We can't afford carpets. So you can hear your shoes clicking on the linoleum at the World Bank.

[Jeff Guo]

Yeah, yeah. At the World bank, the goal is not to make money. It is to fight poverty.

[Waylon Wong]

And about 10 years ago, the largest Ebola outbreak in history occurred in west africa. More than 10,000 people died. Michael and his colleagues were sitting in that not so cushy office in D.C. thinking, what we really need is some kind of international pandemic insurance so that poor countries could get some help.

[Jeff Guo]

So in 2016, he and his team came up with a creative new use for catastrophe bonds to share the risk of pandemics. They basically went around designing their own custom pandemic insurance policy.

[Michael Bennett]

And so we came up with A list of 6 disease types which were believed by the medical experts to be most likely to cause a significant global type pandemic.

[Jeff Guo]

At the top of that list of threats was, of course, Ebola. Also on the list was pandemic influenza, like the type that swept through the world right after World War I, as well as, you know, a couple other types of viruses. The World bank went around to investors asking them, hey, do you want to bet against a pandemic caused by one of these six types of viruses?

[Waylon Wong]

Okay. So, of course, they didn't literally say that, but that's the essence of what a cat bond is. And the World bank ended up raising more than $300 million worth of these new pandemic cat bonds.

[Jeff Guo]

So investors agreed that if a global pandemic happened in the next few years, some or all of those $300 million would go to the World bank to help developing countries. And in the meantime, the World bank would be paying them a decent amount of interest, like tens of millions of dollars a year.

[Michael Bennett]

People thought, this is an extremely innovative way to use the Cap bond market. No one had ever done it before.

[Waylon Wong]

The World Bank's first ever pandemic bond was set to last for three years starting in 2017. By 2019, some people were criticizing the World bank for this deal because here these investors were making fat profits. And what were the chances even that there would be a worldwide pandemic that could trigger this bond? One famous economist called the whole thing an embarrassing mistake.

[Jeff Guo]

But then came the winter of 2020, and we all know what happened in 2020. The coronavirus and coronaviruses were one of the six viruses covered by the World Bank's pandemic bond. And by April, it was official. The bond triggered the international investors lost their money. Hundreds of millions of their dollars went to the World bank to fund COVID 19 relief efforts in some of the poorest countries in the world.

[Michael Bennett]

Well, I mean, you never feel great about a trigger in this market because it means something really catastrophic is occurring. You know, it's the same with any insurance you buy, right? You don't buy life insurance hoping you die the next day, or you don't insure your house. Really rooting for a fire. I think all insurance is, you know, you're putting it in place, hoping you never use it.

[Waylon Wong]

Nowadays, entire nations are turning to cat bonds to protect them from the risk of natural disasters. Michael and his team at the World bank kind of pioneered the idea. They've been helping countries design their own catastrophe bonds. They've worked with the governments of Mexico, Chile, and Colombia, the Philippines.

[Jeff Guo]

These are all countries that face serious risks from hurricanes and earthquakes, but who also have fairly developed economies, like in Jamaica. About five years ago, Jamaican officials were shopping around for some more advanced financial tools to protect themselves from hurricanes. Back then, Fayval Williams wasn't yet the minister of finance, but she was a top official, and she remembers the conversations.

[Planet Money Narrator]

We all realize that hurricanes are inevitable, and we can't just sit here and hope to, you know, go hat in hand afterwards seeking support that we had to be proactive.

[Waylon Wong]

In 2021, Jamaica worked with the World bank to offer its very first catastrophe bond to international investors. Now, the way they're designed, the government only gets a payout if a really serious hurricane passes over Jamaica. There are actually specific meteorological requirements. The bond documents have this map of Jamaica divided up by a grid. And for the bond to trigger, there has to be at least this AM of air pressure in this part of the grid.

[Jeff Guo]

And Jamaica's hurricane bonds, they have had their critics because they're not cheap. Last year, Jamaica issued $150 million worth of these bonds. And Faivel says they have to pay their investors about 7% interest. That's more than $10 million a year. And the chances of the bond actually triggering are pretty low.

[Waylon Wong]

Take Hurricane Barrel. Last summer, it hit the southern coast of Jamaica with category four winds, caused an estimated $995 million of damage. But the Jamaican catastrophe bond still didn't trigger. After Hurricane Beryl, people had a lot of questions for Faywal's predecessor, the previous Minister of Finance, Nigel Clark. He was the one who originally set up the bond, and they were asking him, like, why are we paying millions for insurance that doesn't pay out?

[Planet Money Narrator]

And I recall Minister Clark coming to Parliament.

[Waylon Wong]

So this is a grid. If you look on the screen with.

[Planet Money Narrator]

The map with the grid, and each.

[Waylon Wong]

Of those squares or triangles corresponds to a centralized air pressure.

[Planet Money Narrator]

Minister Clark explaining to the parliament and by extension the people of Jamaica, this catastrophe bond, why it didn't trigger.

[Waylon Wong]

By time it went through that southern grid, the air pressure was 959, just outside of the. Of the threshold.

[Planet Money Narrator]

Minister Clark saying just because it didn't trigger is no reason not to continue to have it. It's an insurance policy.

[Waylon Wong]

Fayvo's predecessor explained that for smaller hurricanes, Jamaica has a whole portfolio of other financial safety nets. It has multiple rainy day funds, emergency loan agreements, other types of insurance.

[Jeff Guo]

These cat bonds, they're designed only to cover those rare, once in a generation hurricanes.

[Planet Money Narrator]

If we were to try to have.

[Waylon Wong]

Insurance cover everything, it would be far too expensive. And if we were to.

[Jeff Guo]

So when Jamaica went to the market with its catastrophe bonds, the country knew what it was buying. It knew how much interest it would have to pay investors and how much insurance it wanted, and that it would only pay out if there was a hurricane the size of, well, the one that came next.

[Waylon Wong]

This year, Hurricane Melissa was like the definition of that once in a generation hurricane. Within a week and a half, the cat bond officially triggered. And Faivel says she was surprised at how tuned in the whole country was.

[Planet Money Narrator]

It was on the tongues of everyone. There are all kinds of interviews on radio and so on, articles written in the paper. Everybody was talking about it, who never knew about a cat bond knew about it.

[Waylon Wong]

Then, thanks to its cat bond, Jamaica is going to get $150 million. In fact, the money just hit the country's bank account this week.

[Planet Money Narrator]

I am hoping that investors globally will see this as a market to support, because behind the dollars are people, real people with lives, who would not have anything else to help them. And here we are now having resources to help us with the reconstruction.

[Jeff Guo]

You know, as this market for catastrophe grows, as catastrophe bonds become more and more mainstream, what it's doing is making the market for insurance bigger and hopefully more competitive.

[Waylon Wong]

So the more investors who get into cat bonds, then if markets work like they're supposed to, the better rates that countries like Jamaica can get and the better rates insurance companies can get on the reinsurance they need. Right now, the price of reinsurance is actually going down in part because of competition from cat bonds.

[Jeff Guo]

The whole point of cat bonds is to share risk with people outside of the traditional insurance markets. And as the weather gets more and more chaotic, as the risk of catastrophe grows, it's maybe not a bad idea to find more and more ways to share that risk.
