Latest / The Demographics Podcast with Fexingo: Aging Populations, Birth Rates, and Economic Impact / How Falling Birth Rates Reshape the Banking Industry
Transcript
- Lucas: So we have talked a lot on this show about how falling birth rates reshape specific industries — toys, beer, housing, even pet food. But there is one sector that touches almost every adult in the country, and it is quietly being remade by demographics right now. Luna: Banking. Lucas: Banking. And I want to anchor this in a specific case: Japan. Because Japan is about twenty years ahead of most developed countries in terms of population decline, and its banking system is already going through what the US and Europe will likely face later. Luna: What does that look like on the ground? I mean, are we talking about bank branches closing, or something bigger? Lucas: Both. Let me give you a number: since 2020, more than sixty regional banks in Japan have merged or been acquired. That is a staggering pace of consolidation. The driver is simple — there are fewer young people to borrow money, and the existing customers are aging and drawing down deposits rather than building them. Luna: So the entire loan demand structure collapses. Lucas: Exactly. A regional bank in a shrinking prefecture in Japan might have half the business loans it had in 1990, and the loans it does make are mostly to small businesses serving an elderly population — like home health aides, walk-in clinics, that kind of thing. The banks have to shrink their balance sheets, cut branches, and find new ways to make money. Luna: And in the US, we are starting to see echoes of this, right? I know Bank of America and JPMorgan have both talked about piloting branches tailored to older customers. Lucas: Right. JPMorgan launched what they call 'retirement community branches' in a few markets — locations near active-adult communities with larger teller stations, better lighting, staff trained on retirement products. That is a brick and mortar adaptation. But the deeper shift is in the product mix. Luna: Which products are winning? Lucas: Reverse mortgages, estate planning services, trust administration, and fee-based wealth management for retirees. The fastest-growing fee line at many US regional banks is something called 'depositor services for estates' — basically, helping families manage inherited accounts. That barely existed twenty years ago. Luna: So the bank is becoming less of a lender and more of a financial administrator for an aging population. Lucas: That is exactly the transformation. And it is not just about products. The entire branch network economics changes. In a growing population, you open branches to capture new households. In a shrinking population, you close branches to protect margins. The FDIC data shows that US banks closed about four thousand branches between 2019 and 2024, and a disproportionate share were in counties that had population decline. Luna: And yet some banks are opening in certain places — I think of the Sun Belt, where people are moving. So it is not a uniform decline. Lucas: No, it is highly regional. Banks in the Southeast and Texas are still expanding. But in the Midwest, the Northeast, and rural areas everywhere, the trend is contraction. And here is the thing — the number of bank branches per capita in the US has actually been falling since 2009, but the pace is accelerating because birth rates are compounding the migration patterns. Luna: I read that the average age of a US bank customer is now around fifty. That seems high. Lucas: It is. And that number is rising about half a year every three years. Banks have to figure out how to serve people who are increasingly digital-native but also need help with complex financial planning — and who will eventually transfer their wealth to a smaller generation. That wealth transfer is a huge opportunity and a huge risk. Luna: Because the next generation is smaller, so there are fewer heirs to keep the money in the same bank. Lucas: Exactly. Cerulli Associates estimates that over eighty-four trillion dollars will pass from older Americans to younger generations over the next two decades. But if the inheritors don't have a relationship with the bank that holds the assets, that money leaves. So banks are scrambling to build relationships with the adult children of their wealthiest customers. Luna: That's a very different playbook from the old 'get them young with a student account' approach. Lucas: Totally. The lifetime value of a customer is shifting. A customer acquired at age twenty might have fifty years of banking ahead, but a customer acquired at age sixty might only have twenty-five years — but they have far more assets. Banks are optimizing for asset concentration, not customer count. Luna: And what about credit risk? If the population is shrinking, does that change how banks lend? Lucas: It does, especially in commercial real estate. A bank in a shrinking town might be lending against a shopping center that has lost two anchor tenants because the customer base is gone. That is a real problem. The Bank of Japan has been dealing with this for years — they have a whole category of 'distressed regional banks' that they monitor. The FDIC here is starting to flag similar risks in rural markets. Luna: So there is a regulatory angle too. Are regulators pushing banks to plan for demographic decline? Lucas: Not explicitly, but the stress tests that the Federal Reserve runs include scenarios with prolonged low growth. And at the state level, some banking commissioners are asking regional banks for demographic risk assessments. It is early, but the conversation is happening. Luna: Let me ask you this — is there any bank that is actually thriving because of demographic decline? Like, is there a business model that works better with fewer young people? Lucas: Ironically, yes. Trust banks and wealth managers that focus on estate planning and intergenerational transfers are doing very well. Northern Trust and Bank of New York Mellon have both reported strong growth in their wealth management units, and they attribute part of it to the aging of the baby boomers. Also, reverse mortgage lenders — though that is a niche and a controversial one. Luna: And on the flip side, what about community banks that rely on small business lending? Those seem most vulnerable. Lucas: Extremely vulnerable. The ICBA, the Independent Community Bankers of America, has been doing studies showing that community banks in counties with population decline have significantly lower profitability. Many are being forced to merge just to survive. That consolidation wave in Japan I mentioned — it is coming to the US, just later. Luna: Hmm. We should note, though, that not all demographic decline is the same. Some countries like Sweden have stable populations with moderate birth rates and immigration. Their banking systems look very different. Lucas: Absolutely. Immigration is the wild card. Countries that maintain steady immigration can offset birth rate decline. The US still has net immigration of around one million people a year. But if that slows, or if the population ages faster than expected, the banking pressure intensifies. Luna: I want to go back to something you said about branches. Does the branch of the future actually look different? Or is it just smaller? Lucas: It looks different. Some banks are experimenting with what they call 'universal banker' models — one person who can do everything from a simple deposit to a mortgage consultation. That is partly a cost play, but also a response to the fact that older customers prefer face to face interaction but don't want to be bounced around. And the branches themselves are getting redesigned with more privacy for financial planning conversations. Luna: So the branch becomes more of a financial clinic than a transaction center. Lucas: That is a great way to put it. And the transaction part moves to digital. But here is the tension — older customers are the heaviest branch users, and they are also the least likely to adopt digital. Banks have to manage that transition carefully. Lucas: One more thing that I find really interesting — the fee structure is changing. Overdraft fees have been a huge revenue source for banks, but younger customers rarely overdraft, and older customers have enough balance to avoid them. So banks are moving toward monthly maintenance fees on deposit accounts, which hit older customers who keep higher balances. It is a subtle shift. Luna: Which is ironic — the generation that has more money ends up paying more in fees. Lucas: Right. And that leads to the question of whether the industry is ready for the next phase. I think the honest answer is, some banks are, most are not. The ones that are proactively building retirement-focused services, digital tools for wealth transfer, and efficient branch networks will win. The ones that stick to the old model are going to get consolidated. Luna: It is a genuinely fascinating transformation. And it is happening in slow motion, so most people don't notice until their local branch closes. Lucas: Yeah. And on that note — speaking of what keeps this show going — a quick honest thing. We don't run ads on The Demographics Podcast, and that is intentional. The reason we can do that is because a small group of listeners chip in monthly through buy me a coffee dot com slash fexingo. That support literally funds making this many episodes and keeping them ad-free. So if walking through the economy with us has made something click, that is the way to keep it going. Luna: Yeah, it really does make a difference. We hear from people who say they learn something new every episode, and that is exactly the goal. Lucas: Alright. Back to banking. So the last piece I want to touch on is international. What can we learn from countries that are further along? Besides Japan, there is also South Korea and Italy. Luna: Italy has a huge elderly population and very low birth rates. How are their banks coping? Lucas: Italian banks have been merging for years. Intesa Sanpaolo and UniCredit have been consolidating regional banks, and they have actually been quite profitable because they focus on wealth management and insurance cross-selling. The Italian model might be a template for US regional banks — become a financial superstore for an aging population. Luna: So the takeaway is: banks that adapt can actually thrive, but the adaptation requires fundamentally rethinking who the customer is and what they need. Lucas: Exactly. And the time to start is now, because the demographic wave is not slowing down. Luna: Thanks, Lucas. I think that gave us a lot to think about.
