Transcript
- Lucas: So we talk a lot on this show about yield — how ultra-wealthy families squeeze returns out of private credit, structured notes, even art funds. But there's one asset class that consistently delivers 300 to 500 basis points over SOFR, and it's almost never discussed outside of institutional circles. I'm talking about catastrophe bonds. Luna: Cat bonds. I've heard the term, but honestly they always felt like something only pension funds and Swiss reinsurers touch. How do they actually work for a family office? Lucas: Well, the basic structure is pretty elegant. A sponsor — say, a large insurance company — wants to offload some of its hurricane or earthquake risk. So it creates a special-purpose insurer, usually domiciled in Bermuda, and issues bonds. Investors buy the bonds and earn a floating coupon, typically SOFR plus a spread that can range from 300 to 800 basis points. Luna: And the risk is that if the hurricane actually hits, you lose principal? Lucas: Exactly. If a predefined trigger event occurs — say, a Category 4 hurricane making landfall in Florida with insured losses above a certain threshold — the bond is either partially or fully written down, and the proceeds go to the insurer. If no trigger event occurs during the bond's term, investors get their principal back plus the coupon. It's basically selling insurance against natural disasters in bond form. Luna: And this market has grown meaningfully? Lucas: Significantly. As of mid-2026, the outstanding cat bond market is around $45 billion globally. That's up from maybe $20 billion a decade ago. And the performance has been strong — the Swiss Re Cat Bond Index has delivered an annualized return of about 6% since 2000, with very low correlation to equities and investment-grade credit. Luna: So it's a true diversifier. But how does a family actually get in? I assume you can't just buy these on Schwab. Lucas: No, you can't. The primary market is institutional — minimum tickets are usually $1 million and up. But there are a few paths for high-net-worth investors. One is through dedicated ILS funds — insurance-linked securities funds — that pool cat bonds and other reinsurance risks. AUM in those funds has grown to roughly $100 billion globally. Another path is through a family office's direct allocation if they have the scale and the expertise to analyze the risk models. Luna: What about the secondary market? If you need liquidity, can you sell before maturity? Lucas: There is a secondary market, but it's thin. Most cat bonds trade over the counter through a handful of broker-dealers. Bid-offer spreads can be wide — sometimes 50 to 100 basis points — and you may not get a quote instantly. So this really is a buy and hold asset class. You need to be comfortable locking up capital for three to five years. Luna: And tax treatment? Because that's always the follow-up on this show. Lucas: Right. Most cat bonds are issued by special-purpose vehicles in Bermuda or the Cayman Islands, so they're typically treated as portfolio income for U.S. investors. That means ordinary income rates, not capital gains. But worth noting: some of the ILS fund structures use offshore feeder funds, which can complicate the tax situation. You definitely want a tax advisor who understands cross-border insurance structures. Luna: So what's a realistic allocation for a family office? One percent? Five? Lucas: Most institutional investors allocate between 2% and 5% of their fixed-income portfolio to cat bonds. For a family office, I'd say 2% to 3% of total AUM is a reasonable starting point, treating it as an alternative fixed-income sleeve. You're not going to put 10% into this — the liquidity constraints and tail risk are real. But as a diversifier that offers a genuine yield pickup, it makes a lot of sense. Luna: And we should mention — there have been years where cat bonds actually lost money. 2017 with Hurricanes Harvey, Irma, and Maria, for instance. Lucas: Absolutely. 2017 was a reset moment for the asset class. A wave of bonds were triggered, and investors lost significant principal. But the market learned from that — subsequent bonds have had tighter risk modeling, higher attachment points, and more diversification across perils. And the long-term track record still looks compelling. Since 2000, the cat bond market has had only two negative calendar years: 2017 and 2011, which was the year of the Tohoku earthquake and the New Zealand earthquakes. Luna: And the spreads have come down a bit as more capital has flowed in, right? Lucas: They have. In the early 2000s, you could get spreads of 800 to 1000 basis points. Now the average is closer to 350 to 400 basis points over SOFR. But that's still a healthy premium compared to high-yield bonds with comparable default risk. And the correlation with markets is near zero, so you're getting a genuine diversification benefit. Luna: This might be the single best example we've covered of a 'non-correlated return stream' that actually lives up to the name. Lucas: I think you're right. And it's a reminder that the ultra-wealthy can access asset classes that simply aren't available to retail investors. The cat bond market is one of those. If you're managing a $100 million-plus portfolio, it's worth a conversation with your investment advisor. Luna: And if you're managing a much smaller portfolio, well, that's where listener support comes in — keeps us making episodes like this one. Lucas: Yeah, we should say — a handful of listeners do chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds us making this many of these deep-dive episodes. No ads, no sponsors, just listener support. Luna: It makes a real difference. And we appreciate it. Lucas: So back to cat bonds — one thing I want to emphasize is the role of parametric triggers versus indemnity triggers. An indemnity trigger is tied to the actual insured losses of the sponsor. A parametric trigger is based on a physical parameter — wind speed, earthquake magnitude, rainfall — measured by independent agencies. Parametric triggers are more transparent and settle faster, which is why they've become more popular. Luna: Which do investors prefer? Lucas: Generally, parametric. Because there's less moral hazard — you're not relying on the sponsor's loss adjustment process. If the wind speed at a specific weather station exceeds 120 knots, the bond triggers, period. The trade-off is basis risk: the sponsor might experience losses that aren't captured by the parametric trigger. But for investors, the clarity is worth it. Luna: And what about the risk of multiple events in a single year? Like 2017? Lucas: That's the tail risk. Most cat bonds cover a single peril per bond — say, U.S. hurricane or Japan earthquake. But if you buy a diversified ILS fund, you're effectively buying a portfolio of dozens of bonds across different perils and regions. The math works because hurricanes in Florida and earthquakes in Japan are essentially uncorrelated. The risk of a truly catastrophic year — say, three major hurricanes hitting the U.S. in one season — is real but priced in. Luna: So the key takeaway: catastrophe bonds offer a genuine diversifier with a yield pickup, but they require patience, due diligence, and institutional-level access. Lucas: Exactly. And if you're a family office that can handle the illiquidity and the complexity, they're worth a look. As of June 2026, the market is healthy, spreads are attractive relative to other yield instruments, and the diversification case has only gotten stronger as climate change increases the frequency of severe weather events. Luna: Great angle for episode 70. Next time, maybe we look at how wealthy families use reinsurance sidecars — that's another ILS structure we haven't touched. Lucas: Noted. We'll add it to the list.
