Ray Dalio with David Rubenstein: How Countries Go Broke (Transcript)

Read the full transcript of co-founder and co-chairman of the Carlyle Group David Rubenstein in conversation with Join Bridgewater founder Ray Dalio on “How Countries Go Broke”, on June 26, 2025, at The 92nd Street Y, New York.

The Mechanics of National Debt: A Conversation with Ray Dalio

DAVID RUBENSTEIN: So thank you very much for doing this. How long did it take you to write this book? How many books have you now written?

RAY DALIO: Four.

DAVID RUBENSTEIN: Four. Okay. And how long does it take to write a book like this?

RAY DALIO: This is research that I’ve done over a long period of time. So putting it together and getting it out, I would say on a part-time basis, maybe over a year.

DAVID RUBENSTEIN: So you built the biggest hedge fund in the world. What’s the relative pleasure of building the biggest hedge fund in the world versus writing a book that’s a bestseller?

RAY DALIO: You know, as you would know, probably it’s a stage in life thing. There’s a stage in life where you compete and you build something, and then there’s a stage in life where you’re passing things along. So at this stage in life, you in your way, me in my way, it’s a great joy to be able to pass along what I’ve learned. So I’m loving it.

The Purpose Behind the Book

DAVID RUBENSTEIN: Okay, so this book is designed to make people feel good or to scare people?

RAY DALIO: Neither. I wanted to convey the mechanics, the cause-effect relationships, so that people can understand what’s going on and then navigate it. I think it’s a book that will make people worry. But I have a principle which is: if you worry, you don’t have to worry. And if you don’t worry, you need to worry. Because if you worry about something, then maybe you’ll prevent what you’re worrying about.

DAVID RUBENSTEIN: So when did you decide to become a writer as opposed to just an investor? I mean, a lot of great hedge fund investors just keep sitting in front of screens and so forth. When did you say, “I want to do more than sit in front of screens?” Was that a couple years before you decided to exit Bridgewater?

RAY DALIO: No, it was maybe 35, 40 years ago. What I learned was that whenever I was making decisions, if I would pause and reflect and write down the criteria that I used to make that decision, it would make me think more deeply about it. And then I learned that I could put those into code and then back-test them so I would know how my decision-making would work.

And so right from then, 35 years ago, that’s how I really built Bridgewater. What are the criteria? Test the criteria over a period of time and then form a game plan. So I’d say 35 years ago, I’ve written down—I call these things principles—I’ve written down probably a thousand of them or something.

The Making of an Investor

DAVID RUBENSTEIN: For those who haven’t followed the hedge fund world, you’re from Long Island, you went to Long Island University. You would say you were not a superstar in high school, on the contrary. But you did very well at Long Island University. And eventually you got into Harvard Business School and you started your career. And your career almost went south when you punched your boss in the mouth, right?

RAY DALIO: No, that was when my opportunities began. I got fired. When I got fired, then I started.

DAVID RUBENSTEIN: So you got fired, you started your own firm, and you borrowed some money at some point from your father because the firm hadn’t done that well. Did you ever think that maybe you weren’t going to make it?

RAY DALIO: So yeah, let me tell you about that incident because it was one of the worst cases and one of the best cases for me. So this is 1980-81. And I had calculated that the United States lent more money to countries than they were going to be able to pay back and that there would be a big debt crisis.

And then in 1982, Mexico defaults on its debt. And I got a lot of attention because I anticipated this and I thought I was right, and I couldn’t have been more wrong. I thought we were going to have a big economic crisis because of this. And what happened instead was the stock market went up, they eased monetary policy, and I made a terrible mistake. And it cost me money.

I was so broke that I had to borrow $4,000 from my dad in order to pay for family bills. And this was painful. And that changed my approach to everything in two ways. First, it made me think, “How do I know I’m right?” It gave me the humility I needed to balance with my audacity. And it let me understand how to play this game going forward.

And I understood the power of diversification and how diversification could reduce risk by up to 80% without reducing returns. And that was then the foundation of Bridgewater. And then from then on it was straight up because of the lesson I learned—writing down these things and experiencing and making the most out of mistakes as learning experiences.

The Power of Diversification

DAVID RUBENSTEIN: As an investor, you always have ups and downs. Nobody does everything perfectly, not even Warren Buffett, right?

RAY DALIO: But you know what changed from that point? The returns in my 30-some-odd years since doing that—since that point—were about 11.8% return with no year down significantly other than 2020 during COVID, and that was down 13%. But the other years were down like 2% because I learned the power of diversification.

One of the things about diversification is that you can reduce the risks without reducing the return. My mantra is “15 good uncorrelated return streams.” Because if they’re engineered to have about the same expected return and you have that kind of diversification, you will lower the risk by about 80%, which raises the return-to-risk ratio by a factor of five.
