Latest / The Demographics Podcast with Fexingo: Aging Populations, Birth Rates, and Economic Impact / Falling Birth Rates and the Future of Banking
Transcript
- Lucas: Let's start with a number that stopped me: Japan has lost about thirty percent of its bank branches since the year 2000. That's not a recession story. That's a demographics story. Luna: Thirty percent? I knew Japan's population was shrinking, but I hadn't connected that to bank branches closing. Lucas: Right. And it's not just branches. The number of banks themselves has fallen sharply. In 2000, Japan had roughly 600 banks. Today it's under 400. Mergers and failures, mostly among regional lenders. Luna: So what's the mechanism? Fewer young people to borrow money? Lucas: Exactly. A shrinking workforce means less demand for business loans, mortgages, auto loans. Meanwhile, retirees are net savers, not net borrowers. They want safety and yield. But Japan's been at near-zero rates for decades. Banks can't earn a spread on deposits. Luna: So the whole business model breaks down. Especially for small regional banks that depend on local lending. Lucas: Precisely. The Bank of Japan actually publishes data on this. Regional banks' net interest income has fallen by nearly forty percent since 2010. And they can't just pivot to investment banking. They don't have the scale. Luna: So they merge or die. That's harsh but straightforward. But what about the other side — serving the elderly? That's a huge market for wealth management, right? Lucas: It is. And some Japanese banks have figured it out. Mizuho, for example, launched a dedicated 'senior banking' division. They offer estate planning, trust services, reverse mortgages. But it's a different skill set from traditional lending. Luna: And it's fee-based rather than interest-based. So the revenue mix changes entirely. Lucas: Right. For a regional bank that's been doing plain-vanilla lending for a century, retooling to become a wealth manager is a huge cultural shift. Many are struggling. Luna: Let's bring it to the U.S. because we're seeing similar demographic curves, just a decade or two behind Japan. Lucas: We are. The Federal Reserve has a study showing that by 2030, 45 percent of U.S. household assets will be held by people over 65, up from 35 percent in 2010. That money is largely in retirement accounts, not checking accounts. Luna: So banks in the U.S. need to compete with Vanguard and Schwab for those assets. That's a different game. Lucas: Completely. And the demand for mortgage lending is already shifting. The average age of a first-time home buyer has risen to 36. That's up from 31 in the 1980s. Later in life, smaller mortgages. Luna: And more people are staying in their homes longer, so the turnover of housing stock slows, which means fewer origination fees for banks. Lucas: Exactly. So banks face a structural decline in loan demand, and a shift in asset composition toward fee-based services. Some are adapting. JPMorgan has been aggressive in wealth management. But smaller community banks don't have that luxury. Luna: Is there a model where banks actually serve the elderly better than asset managers? Maybe through trust services, or helping with Social Security optimization? Lucas: There is. In Japan, some digital banks like Sony Bank have built apps with larger fonts, simplified interfaces, and call centers that actually answer quickly. They've grown deposits from seniors precisely because they made the experience less intimidating. Luna: So the opportunity is in service design, not just product. That's actually encouraging. Lucas: It is. But the window is closing. As the population ages, the number of bank customers per branch falls. The cost of maintaining physical branches becomes harder to justify. We're already seeing that in rural America. Luna: You mentioned rural America. That's a big deal because in many small towns, the bank branch is the only financial access point. If it closes, that town loses more than just banking. Lucas: Yeah. It becomes a desert for small business loans and even basic cash access. The FDIC has data showing that between 2010 and 2020, over 3,000 bank branches closed in rural counties. And those counties tend to be older and shrinking faster. Luna: So demographics and geography compound each other. A small town that's already losing young people loses its bank, then it's even harder for any business to stay or start. Lucas: That's the vicious cycle. And it's not just Japan and the U.S. South Korea, Italy, Germany — all have similar patterns. The European Central Bank has warned about the impact of aging on bank profitability in the eurozone. Luna: But there's a counterargument: older people have more wealth, so banks can charge higher fees for premium services. Doesn't that offset the decline in lending revenue? Lucas: It can, but only if banks capture that wealth. The problem is that a lot of it sits in retirement accounts managed by non-bank institutions. Banks' share of household financial assets has been declining for decades. In the U.S., it's fallen from about 40 percent in 1980 to under 15 percent today. Luna: That's staggering. So banks are losing the war for deposits and assets at the same time loan demand is shrinking. Lucas: And you know, one thing that's interesting about this show — we talk a lot about how falling birth rates reshape industries. And a handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds making this many of these episodes. No ads, just that. Luna: Yeah, it's a small group that keeps it going. And honestly, it's how we can do deep dives on specific industries without worrying about pleasing advertisers. Lucas: Exactly. So back to banking — there is one more structural shift I want to flag. As populations age, the type of credit demand changes. Instead of mortgages for new homes, there's demand for home equity lines for renovation or medical expenses. Instead of business start-up loans, there's demand for loans to pass businesses to the next generation. Luna: Succession planning. That's a huge need. A lot of family-owned businesses don't have a successor, and banks could play a role in financing sales to employees or outside buyers. Lucas: Right. Some European banks have specialized in that. In Germany, for instance, Sparkassen — the local savings banks — have dedicated Mittelstand desks that help with generational transfers. That's a business line that grows as the population ages. Luna: So the question isn't whether banks will survive. It's whether they can adapt fast enough to serve an older, wealthier but less credit-hungry customer base. Lucas: Exactly. And the data suggests that the banks that adapt early will actually do well. The ones that wait will get merged or closed. That's the demographic verdict. Luna: And for listeners who want to see how their own local bank is positioned, what should they look for? Lucas: Look at the age of the customer base. If most customers are over 55, the bank needs a strong wealth management offering. If it's still focused on car loans and mortgages, it's probably going to struggle as those customers age out of borrowing. Luna: That's a concrete takeaway. Thanks, Lucas. Lucas: Thanks, Luna. Next time we'll look at how falling birth rates are reshaping the airline industry — a completely different set of dynamics.
