Latest / The Demographics Podcast with Fexingo: Aging Populations, Birth Rates, and Economic Impact / How Falling Birth Rates Reshape the Insurance Industry
Transcript
- Lucas: So here's a number that's been sitting with me: in Japan, there are now more adult diapers sold each year than baby diapers. That's been true for a while, but what struck me is how that kind of inversion is now showing up in the insurance industry. Luna: Really? I mean, we've talked about how aging affects everything from toys to hotels, but insurance feels like it's built on predictions about who's alive and who's not. So if the pyramid flips, the whole model has to flip too. Lucas: Exactly. And that's what we're digging into today. The insurance industry is essentially a bet on mortality and morbidity tables. For over a century, those tables looked a certain way: relatively short lifespans, a big cohort of young people paying premiums. But now, birth rates are falling almost everywhere, and lifespans are stretching. The two moves have basically inverted the risk profile. Luna: So who's the typical customer now, and what are they buying? Lucas: That's the crux. For decades, the bread and butter product was term life insurance, designed to protect a family's income if the primary earner died early. But when you have fewer children and longer lives, the fear of dying young drops, and the fear of outliving your savings goes up. So the product that's exploded is the annuity. In the U.S., annuity sales hit record numbers in 2025, somewhere around four hundred billion dollars. That's not a typo. Luna: Wow, that's a massive number. And it makes sense, right? If you're a retiree with no kids to lean on, you're the one who carries the longevity risk. Lucas: Exactly. And it's not just the products themselves. The actuarial assumptions are shifting. Insurers used to price life insurance assuming you'd live to about seventy-eight. Now they're pricing for ninety, ninety-five, maybe even a hundred. That changes the reserve requirements, the premiums, and the investment strategy. Luna: Right, because they're holding your money for longer, so they need different assets to match those long liabilities. Lucas: Precisely. That's why you've seen insurers lean heavily into long-duration bonds, infrastructure projects, even timberland, all to get predictable cash flows over thirty, forty, fifty years. It's a complete change from the old model, where they'd pay out sooner and needed more liquidity. Luna: And what about health insurance? Because with an older population, the cost of care—especially chronic conditions like dementia—is a huge and growing risk. Lucas: That's the next frontier. In Japan, for example, insurers have started offering policies specifically for dementia care. You get a lump sum when you're diagnosed, which you can use for home modifications, caregiving, whatever. And they're selling really well, because people see their parents going through it and they're terrified of the same thing happening to them. Luna: And in the U.S., we're seeing a rise in hybrid long-term care policies, the ones that combine life insurance with a long-term care rider. That seems like a direct response to the fear of blowing through your savings on a nursing home. Lucas: Right. The old standalone long-term care insurance basically failed because people bought it, never used it, and premiums went through the roof. The hybrid is smarter because it addresses both risks at once. If you don't need care, your beneficiaries get the death benefit. If you do, you can tap it early. It's a hedge against either scenario. Luna: And speaking of beneficiaries, what happens when there are no kids to leave the money to? That's where I noticed something interesting in Japan—policies that pay for your funeral or even your pets. Lucas: Oh, that's a great point. The 'last expense' insurance, they call it. In Japan, there's a product that will cover the cost of your funeral and even set aside money for your cat or dog after you're gone. It sounds almost heartwarming, but it's really a rational response to a society where more and more people are aging alone, with no spouse and no children. Luna: It is a bit lonely though, thinking about it that way. But it also shows how creative insurers are getting to meet a real need. Lucas: And it's not just Japan. We're seeing similar products pop up in South Korea, Italy, even parts of the U.S. The 'simplified issue' policies, which require no medical exam and pay out within a few days, are increasingly marketed to seniors who want to cover final expenses without burdening family. Luna: So the product mix is shifting dramatically. But what about the people selling it? How are agents and brokers adapting to this new demographic reality? Lucas: That's a really interesting angle, because the salesforce itself is aging. Many experienced agents are retiring, and younger agents don't have the same instinct for selling life insurance to families with young kids—that market just isn't there like it used to be. Instead, they're learning to sell volatility, to sell longevity, to sell peace of mind in retirement. Luna: And that requires a different skill set, right? More financial planning, more listening, less hard sell. Lucas: Yeah, and it's one of the reasons we do this show—to help people understand these shifts before they hit them. Insurance is one of those things nobody wants to think about, but it touches everyone. And here's the thing: we keep this podcast free and ad-free because we think that kind of understanding should be accessible to anyone, not just people who can afford a financial advisor. Luna: And we're able to do that thanks to listeners who support the show directly. If you've gotten something useful out of these conversations, and you want to keep them going, you can help at buy me a coffee dot com slash fexingo. Lucas: Yeah, it's just a simple way to keep the lights on and the microphones on. No ads, no sponsors, just the topics we find genuinely fascinating. And speaking of fascinating, let's get back to the investment side of insurance, because that's where the real macro effect shows up. Luna: Yes, because insurers are among the biggest institutional investors in the world. Their asset allocation decisions have ripple effects across all markets. Lucas: Absolutely. In the U.S., insurance companies hold over seven trillion dollars in assets. If they're shifting toward longer-duration bonds and alternative assets like infrastructure and private equity, that changes the shape of the capital markets. It's not just about what they buy, it's about what they need to buy to match their liabilities. Luna: So if the population ages, insurers need more long-term, predictable cash flows. That's a structural tailwind for bonds with thirty-year maturities, but maybe a headwind for more volatile assets. Lucas: Right. And it's also a factor in the persistent low interest rates we've seen over the last decade and a half. Insurers are huge buyers of government bonds, which helps keep yields low—especially in places like Japan and Europe, where the population is oldest and the insurance industry is massive. Luna: So there's actually a feedback loop: an aging society buys more insurance, which pushes insurers into long bonds, which keeps long-term rates low, which then affects everyone's borrowing costs. Lucas: Exactly. And that's a connection most people don't make. They see low mortgage rates or low corporate borrowing costs and think it's all central bank policy. But demographic demand for safe, long-dated assets is a huge structural driver underneath. Luna: And what about the shift to annuities specifically? That's a big deal because it moves money from a 'risk pool' to a 'guaranteed income' model. How does that change the insurer's risk? Lucas: It's a different kind of risk. With life insurance, the risk is that you die too soon—the insurer might have to pay out before collecting enough premiums. With an annuity, the risk is that you live too long—the insurer has to keep paying out well past what was expected. So the whole risk management game flips from mortality risk to longevity risk. Luna: And that's why they're so focused on improving longevity modeling, I bet. They need to know exactly how long people are going to live, and how that changes with healthcare advances, lifestyle changes, even climate change. Lucas: Right. And they're using more sophisticated data now—wearables, health records, even genetic testing—to price these products more accurately. But there's a limit to how precise you can get, because the future is inherently uncertain. That's why pensions and insurers often transfer some of that longevity risk to reinsurers, or even to capital markets through longevity bonds. Luna: Longevity bonds—those are pretty niche. Can you explain how they work? Lucas: Sure. Think of a bond where the coupon payments are linked to the actual mortality rate of a certain population. If people live longer than expected, the payments are higher, because the insurer needs more money to cover the extra years. If they die sooner, the payments are lower. It's a way to hedge against the uncertainty of human lifespans. Luna: So it's almost like an insurance policy on the insurance policy. That's pretty clever. Lucas: It is. And the market for these is growing, albeit slowly. The first longevity bond was issued back in 2004, and since then, there have been a few others, but it's still a nascent market. The potential is huge, though, especially for pension funds that are facing underfunded liabilities as their members live longer. Luna: And that brings us to the public pension angle, which we touched on a few episodes ago. But for insurance specifically, what's the takeaway for the average listener? Lucas: I think the takeaway is that insurance is a mirror of society. The products we buy reflect our fears and our hopes. Fifty years ago, the big fear was leaving your family destitute if you died young. Today, the fear is outliving your money, or needing expensive care that you can't afford. And the industry is responding to that, slowly and imperfectly, but it is responding. Luna: And for someone in their thirties or forties listening, what should they be thinking about when it comes to their own insurance planning? Lucas: Look, I'm not a financial advisor, but I think the key is to think about the risks you actually face, not the risks your parents faced. Long-term care insurance, for example, is probably more relevant for us than for earlier generations, because we're more likely to need it and less likely to have children to provide it. And the younger you buy it, the cheaper it is, even if it feels weird to think about. Luna: And annuities, too. It used to be that annuities were a product for people in their sixties. But with interest rates higher than they were a few years ago, some younger people are starting to consider them as a way to lock in a guaranteed income stream for retirement. Lucas: Right. The new retirement landscape is really about decumulation, not accumulation. And the insurance industry is slowly waking up to that. We're seeing more flexible products, more transparency, more innovation. It's not the stodgy industry it used to be, even if it still moves slower than, say, tech. Luna: And that's the key—innovation is happening, but it's happening in response to a demographic tide that's been building for decades. The question is whether insurers can keep up, and whether consumers can navigate the increasingly complex choices. Lucas: Yeah, it's a lot to think about. But I think the fundamental message is that our insurance needs are changing because our lives are changing. And the more we understand that connection, the better prepared we'll be—not just financially, but mentally. Luna: For sure. And with that, I think we've got a solid picture of how falling birth rates and aging populations are reshaping the insurance industry. Thanks for listening, everyone.
