Latest / The Demographics Podcast with Fexingo: Aging Populations, Birth Rates, and Economic Impact / How Falling Birth Rates Reshape the Life Insurance Industry
Transcript
- Lucas: A standard life insurance policy is built on a simple bet: you pay premiums now, and if you die within the term, your beneficiaries get a payout. But what happens when fewer people are born and the ones who are alive keep living longer? The math starts to break. Luna: And that's not just a theoretical question. Japan has been living this reality for decades now, and their life insurance market has already gone through the kind of shift the rest of the world is just starting to see. Lucas: Exactly. Japan's total fertility rate has been below replacement level since the 1970s. Today, nearly 30 percent of the population is over 65. Meanwhile, life expectancy at birth is about 85 years — among the highest in the world. Luna: So for a life insurer, that means fewer young people buying policies, and the ones who do have policies are less likely to die during the coverage period. Seems like a squeeze. Lucas: It's a fundamental reshaping of the product itself. Traditional term life insurance — which pays a lump sum on death — has been declining in Japan for over a decade. Sales of new individual life insurance policies peaked around 2010 and have fallen roughly 20 percent since then. Luna: But insurers still need to sell something. So what are they selling instead? Lucas: They've pivoted hard toward savings-type products and so-called living benefits. These are policies that pay out if you're diagnosed with a critical illness, or need long-term care, or simply survive to a certain age. In Japan, the share of new policies with living benefits has gone from about 30 percent in 2000 to over 60 percent today. Luna: So instead of betting on death, they're betting on life — or at least on expensive health events. Lucas: Right. And the premium structure changes too. A traditional term policy gets cheaper the younger and healthier you are. But in a low-birth-rate environment, the pool of young healthy people is shrinking. So insurers have to either raise premiums on younger cohorts — which makes the product even less attractive — or find different revenue streams. Luna: If today's conversation is giving you a clearer picture of how demographic shifts ripple through industries, that's exactly what this show aims to do. And the reason we can keep these episodes ad-free is listener support. If you've gotten something useful out of it, you can help keep it going at buy me a coffee dot com slash fexingo. Lucas: And we genuinely mean that — this kind of deep dive takes a lot of reading and data-crunching, and knowing listeners find value in it makes it worth doing. So thank you to everyone who's chipped in. Luna: Alright, back to the numbers. What about the other side of the equation — the people who already hold policies? Do insurers just sit back and collect premiums longer? Lucas: They have to manage the longevity risk on their books. If people live longer, the insurer holds the premiums for more years, which is good for investment income, but it also defers the payout. For whole life and universal life policies, that means the reserve requirements change. Regulators in Japan have tightened solvency rules to make sure insurers hold enough capital to cover those longer tails. Luna: And they've also started offloading some of that risk to capital markets, right? Mortality bonds and longevity swaps? Lucas: Yes. Japan's largest life insurers have issued mortality catastrophe bonds — securities that pay investors a high coupon but take a loss if death claims spike unexpectedly. The flip side is longevity-linked securities, which pay out if people live longer than projected. The market for these is still niche but growing. In 2025, there were about two billion dollars in longevity risk transfers globally. Luna: That's small compared to the overall life insurance market, but it shows insurers are desperate to hedge demographic uncertainty. Lucas: And it's not just Japan. Look at Germany, Italy, South Korea. Their fertility rates are all below 1.3. In South Korea, it's 0.72 — the lowest in the world. The life insurance penetration rate there has dropped from about 8 percent of GDP in 2000 to under 5 percent now. Luna: So households are spending less on life insurance even as the population ages. That's a double hit. Lucas: One reason is that younger generations in those countries are delaying marriage and home-buying — two big triggers for taking out a life policy. In South Korea, the average age of first marriage for women is now over 31. That pushes back the whole lifecycle of insurance needs. Luna: And when they do buy, they're more likely to buy online, comparison-shop, and choose low-cost term policies rather than the high-margin whole life products that agents used to push. Lucas: Insurers have responded by trying to bundle living benefits into term policies as a differentiator. For example, some now offer a 'return of premium' feature — if you outlive the term, you get your money back. That turns a pure risk product into something that feels like a savings vehicle. Luna: But that also means the insurer is taking on more investment risk — they have to earn enough on the premiums to refund them later. In a low-interest-rate environment, that's tough. Lucas: Exactly. Japan's ten-year government bond yield has been near zero for years. That crushes the spread insurers can earn on the float. Some Japanese insurers have started investing more in foreign bonds and alternative assets to get yield, which brings currency risk. Luna: And yet the industry isn't collapsing. It's just becoming a different industry. Fewer people buying death coverage, more people buying care coverage and retirement income. Lucas: That's the key takeaway. The product is shifting from a mortality hedge to a longevity hedge. From protecting your family if you die too soon, to protecting yourself if you live too long. Luna: But there's a social equity question here. If insurers raise premiums on young people to cover the risk of an aging book, that makes life insurance even less affordable for the very group that might need it — say, a 30-year-old with a new mortgage. Lucas: And some observers argue that as birth rates fall, the role of life insurance as a social safety net should be reconsidered. In countries with generous public pensions and health care, the need for private death benefits may shrink further. The product becomes more of a luxury for high-net-worth individuals focused on estate planning. Luna: So the mass market for term life — the kind sold to young families — could gradually wither. Lucas: Some data suggest that's already happening in parts of Europe. In France, where fertility is around 1.8 — relatively high by European standards — life insurance premium volume has been flat for a decade in real terms. The growth is all in unit-linked products that are essentially investment funds with a small insurance wrapper. Luna: Which brings us back to the core demographic dynamic: fewer births mean fewer future customers, and longer lives mean each customer stays on the books longer but claims are deferred. The industry's golden age — when baby boomers were young and buying policies in droves — is over. Lucas: And the next act is still being written. We'll be watching how insurers in countries like India and Nigeria — where birth rates are still above replacement — may eventually face the same shift as their populations age. Luna: It's a long-term trend, but one that's already reshaping trillions of dollars in assets. For anyone in the industry or investing in it, the question is: are you positioned for a world where death is less certain than living? Lucas: That's a good place to leave it. Thanks for listening, and we'll be back soon with another angle on how demographics drive economic change.
