Additional Rate Hike Hits the Mortgage Generation Hard While Elderly Households Come Out Ahead

From our other sites

The story

Following the Bank of Japan’s additional rate hike, Japan’s three megabanks — Mitsubishi UFJ, Sumitomo Mitsui, and Mizuho — announced they will raise ordinary deposit interest rates to 0.5% starting November 2nd. That’s 500 times the 0.001% rate seen in March 2024, before the negative interest rate policy was lifted. According to calculations by the Yomiuri Shimbun, this will hurt the household finances of younger generations carrying mortgages, while benefiting older, savings-heavy households. On 5ch, discussion centered on whether this framing is fair, and why more people didn’t lock in fixed rates back when interest rates were low.

Did people really think negative interest rates would last forever? Why didn't they just go fixed? It's baffling how anyone missed that.

Re: #19
If you look at a 100-year interest rate chart, the zero-rate period is clearly the anomaly.
Homebuilders pitched low rates as a golden opportunity plus inheritance-tax planning, and got tons of people to put up apartment buildings under 'sublease' master-lease schemes.
Now the rate-review dates are coming due one after another.
For landlords who are like 80 years old, banks jack the rates way up.
It's fine in city centers where land prices climbed, but rural areas haven't appreciated at all.
Rent hikes aren't even possible under sublease contracts, so collateral value collapses and a wave of 'black-ink bankruptcies' (going under despite being profitable on paper) hits all at once.

Re: #19
Fixed rates cost more than variable because the bank carries the risk of a negative spread (paying out more than it earns). Getting lured in by the lower short-term payment is basically like those 'zan-kure' balloon-payment car loans (residual-value credit plans).

Re: #19
Why? Because you pay down principal while the balance is still big, then make early repayments once rates climb, all while maxing out the mortgage tax deduction (1%, 13 years, obviously). You wouldn't get it — broke people like you can't even afford a house, right?
27AnonymousSep 19, 2026 08:54
Rates are heading up to 1.75% from here.
If they don't raise it, we're in for brutal yen depreciation.

Re: #27
That'd be great news 😆
32AnonymousSep 19, 2026 08:55
Re: #27
Don't they need to push it to something like 4-5% before the weak yen actually corrects?
54AnonymousSep 19, 2026 09:01
Some people mock variable-rate mortgages, but if your plan is to make early repayments once rates rise anyway, isn't variable just fine?
64AnonymousSep 19, 2026 09:04
Re: #54
The reason people take out loans in the first place is that they can't afford early repayments.
65AnonymousSep 19, 2026 09:04
Re: #54
People who actually can do that probably have cash reserves backing them up too, so it's not that big a deal for them.
78AnonymousSep 19, 2026 09:08
Re: #54
Most people on variable rates never planned for that (or can't).

The Baby Boomers clawed their way up from literal scorched earth and drove the postwar economic miracle. Meanwhile the Ice Age generation, grown adults by then, partied all night on disco podiums (the famous 'o-tachidai' dancing of the bubble-era club scene), burst the bubble, buried the country in bad loans, dodged real jobs for irregular work instead, and ran from marriage and child-rearing — and that's why Japan stopped growing.

Re: #62
Didn't the Baby Boomers actually miss the high-growth era's heavy lifting? That was the fearless, reckless generation from the prewar/wartime Imperial Japan years.
124AnonymousSep 19, 2026 09:20
Re: #62
The Ice Age generation was still in high school or younger during the bubble.
84AnonymousSep 19, 2026 09:11
See, I knew it — this was a generational fight all along.
A weak yen favors the young, a strong yen favors the old.
So all that yen-weakness bashing was just old people talking their own book.
91AnonymousSep 19, 2026 09:13
Re: #84
That's really the heart of it, isn't it. That's why the media is desperately pushing for a stronger yen lol.
131AnonymousSep 19, 2026 09:22
Re: #84
So what if a weak yen means young people can't afford a trip to Europe? lol
88AnonymousSep 19, 2026 09:12
You could've just locked in a fixed rate back when interest rates were low — why did people pick variable instead?
94AnonymousSep 19, 2026 09:14
Re: #88
Deflation dragged on for years and the rate gap was huge, so I get why people got talked into variable. Sales reps are smooth operators too.
101AnonymousSep 19, 2026 09:15
Re: #88
Guess people figured ultra-low rates would last forever.
119AnonymousSep 19, 2026 09:18
Young people's pay is rising even faster than that, and their workload is lighter too.
121AnonymousSep 19, 2026 09:19
Re: #119
Nice, if only 'young people' stayed young forever.
128AnonymousSep 19, 2026 09:20
Re: #119
Exactly this. This article seems kind of misleading. Under inflation, it's basically working-age young people who come out ahead — wages rise along with prices, and if you borrowed early, the real value of your repayments shrinks in your favor.
146AnonymousSep 19, 2026 09:26
Re: #131
Losing jobs and wages to a strong yen hurts way more than missing out on a trip abroad lol
151AnonymousSep 19, 2026 09:27
Re: #131 Re: #146
Whether it's a weak yen or a strong yen, I don't think you small-business types have any way to profit either way.
153AnonymousSep 19, 2026 09:28
Re: #146
I'm literally losing wages because of the weak yen. New-grad starting salary is like 300,000 yen, right? But since the yen's worth half what it used to be, that's really just the old 150,000 yen lol lol
164AnonymousSep 19, 2026 09:30
Re: #153
This article is literally the one exposing that claim as false lol
167AnonymousSep 19, 2026 09:31
Re: #164
What's false about it? Back when the monthly salary was 150,000 yen, people could still afford a Louis Vuitton bag — can you now? lol
178AnonymousSep 19, 2026 09:34
Re: #167
Nobody even wants that anymore lol. Young people are out buying the new iPhone instead.
A weak yen means more jobs and higher wages for young people, and it turns out the boomers bashing the weak yen were just bitter about it.
180AnonymousSep 19, 2026 09:35
Re: #178
Pretty sure Android is what's actually gaining share lol lol lol lol lol lol
170AnonymousSep 19, 2026 09:33
So basically, boomers who grew up thinking fixed-term deposits were normal are just demanding a strong yen for their own benefit.
177AnonymousSep 19, 2026 09:34
Re: #170
Old people actually invest more money than people in their 20s though lol. The ones making noise about the rate hike are just the poor ones lol lol lol lol
176AnonymousSep 19, 2026 09:34
There's fixed and variable, and people who went fixed have been paying tens of thousands of yen extra the whole time as insurance against exactly this. Everyone agonized plenty over which to pick when they took out the loan in the first place — no room to complain now.
199AnonymousSep 19, 2026 09:38
Re: #176
Exactly this. When I bought, fixed was in the 1% range and variable was under 1%, some fraction of a point. Almost everyone went variable, and since the mortgage tax deduction was 1%, variable basically meant a negative interest rate lol — the vibe back then was 'anyone who picks fixed is just a scaredy-cat idiot.' Glad I went fixed anyway. Acting entitled while you're benefiting, then crying 'it hurts, it hurts' and blaming the government the second you bear any risk — that's peak stupidity.
200AnonymousSep 19, 2026 09:39
Re: #176
I took out a variable loan 15 years ago, and even at this pace of hikes, I don't think the total will end up exceeding what a fixed loan would've cost. The first 10 years are what really matter, and getting through them at ultra-low rates means I already won the gamble. My financial planner at the time actually predicted this far out and told me fixed made no sense.
185AnonymousSep 19, 2026 09:35
Re: #177
'Investment amount,' huh? lol You need to talk in terms of number of investors or the comparison gets skewed lol. The number of people actually investing skews overwhelmingly young, right? lol
204AnonymousSep 19, 2026 09:40
Re: #185
Investing is done with spare cash, so of course it skews toward older people lol lol. Though past 70 it's basically 'shukatsu' time (a pun on job-hunting vs. end-of-life prep — same pronunciation), so that's about it for you.

Re: #204
That's why I said talk in terms of population. This is just a story about a tiny sliver of boomers who happened to trade stocks. The overwhelming majority of boomers are savers, come on.

Background and Key Points of the Debate

The Bank of Japan lifted its negative interest rate policy in March 2024 and has been raising rates gradually ever since. The three megabanks’ move to raise ordinary deposit rates to 0.5% from November 2nd marks a 500-fold jump from the 0.001% rate of March 2024 — a striking symbol of the shift away from Japan’s long era of ultra-low interest rates. The thread split over whether the simple framing of “rate hikes benefit the elderly while burdening the young” really holds up. The majority of Japanese mortgage holders choose variable rates, so those who borrowed on the assumption that low rates would continue are directly exposed to the increases — but plenty of replies pushed back, arguing that “the risk was already priced in the moment you chose variable” and that “fixed rates were always pricier precisely because they hedge against that risk.” There’s also the question of whether a weak or strong yen actually favors young people more, which resists being framed as a simple generational conflict once you factor in wages and prices rising together. The Yomiuri Shimbun report behind this article estimated the impact on household finances, but it’s worth remembering that the real-world effect varies enormously depending on which type of rate a given household chose and how their savings and borrowing balance out.
