Someone Compared USD/JPY to Blood Pressure, and It's Genius

160 is bad, 90 is bad, and your doctor and your broker are saying the exact same thing.

What's going on

The USD/JPY exchange rate has been a source of anxiety in Japan for years — a weak yen drives up the cost of imports and squeezes household budgets, while an overly strong yen creates its own set of economic problems. Most people understand that extreme moves in either direction are bad, but the financial jargon can make it hard to feel that instinctively.

That changed when one person on Japanese social media posted a simple reframe: think of the dollar-yen rate like blood pressure. Too high (160+) and you're in danger. Too low (90 and below) and you're also in danger. The sweet spot sits somewhere around 110–120 — which, as it happens, is also what a healthy blood pressure reading looks like. The comparison spread quickly, with people piling on to extend the metaphor in ways that turned out to be surprisingly apt.

Comments

Someone compared USD/JPY to blood pressure and honestly? Genius. Over 160 yen? Bad. Under 90 yen? Also bad.
ドル円を血圧に例えた人がいたけど天才だな。160円以上はやばい。90円以下もやばい。
Oh wow……!
なるほど……!
lmao this actually makes sense www
これは分かりやすいwww
Nicely put~
うまいなぁー
This is what “surprisingly fitting” actually means
言い得て妙とはこの事
Two cushions for this one (In Japanese comedy, tossing a cushion — “zabuton” — to a performer is a way of awarding points for a clever joke. Two cushions is high praise.)
座布団二枚
Actually laughed out loud. And yeah, the numbers even line up.
声を出して笑ってしまった。なるほど数字もそれっぽい。
For a second I thought this was about someone with 160 over 90… nope, both numbers are the “upper” reading 💱
一瞬上が160で下が90の人の話かと思ったけどどっちも上の話ね💱
Legit genius. So easy to understand.
ホント天才。とても分かりやすい。
Yeah, this is genius. Forget the “strong yen vs. weak yen” debate — what we actually want is to talk about whether the current rate feels high or low and what it’s doing to everyday life.
あー、これは天才だわ。円高vs円安なんて議論じゃなくて、「今が高い、安い」で生活に対する影響で議論したいもんだね。
Too good… 100 to 120 is the comfortable zone for both blood pressure AND the exchange rate, huh.
天才過ぎる…。100から120が血圧もドル円も良い感じだもんな。
Sitting at 150-something all the time is pretty rough too
常時150台も相当やばい
Nobody is walking around happy with a blood pressure in the high 150s.
血圧150後半でホクホク顔の人間はいないよな
Just stay between 110 and 120, thanks
110から120でいいよ
Actually a solid analogy. Wild swings in either direction are never good.
上手い例えかも。乱高下してもろくなことが無いし
Also, temporarily spiking in one direction is fine — like blood pressure after exercise — but staying stuck there chronically is where the damage sets in, for the economy and the body alike.
しかも、一時的にどっちかに触れるのは(運動後の血圧みたいに)問題ないけど慢性的にどっちかに張り付くと経済(身体)に影響が出るのも同じですね
And the fact that it creeps up due to long-term lifestyle habits… yeah, that tracks ()
高くなるのは慢性的な生活習慣のせいなのがまた何とも()
Medication (read: intervention) can bring it down temporarily, but you have to keep taking it or it climbs back up… and if you don’t fix the underlying condition you’re done for. Yeah, still works as an analogy.
お薬(介入)で一時的に下がるとは思うが、健康な値を維持するには継続的に飲まないとまた上がる…体質改善しないと死ぬ奴って所も良い例えやな…
It really is a great analogy. I suppose yen-buying intervention would be like a strong blood pressure pill. Though I’ve heard hypertension is notoriously hard to cure…
たしかにうまい例えですね 円買い介入は強めの降下剤でしょうかね でも高血圧はなかなか治らないとも聞きますが・・・
Once it crosses 135 you’ve got a problem
上135超えたらやばい
Lately they say anything above 130 is already bad, not just 140.
最近は140どころか、130超えがダメなようで。
Wait, isn’t 130+ already classified as hypertension now?
今たしか血圧130超えると高血圧じゃなかったっけ
Whether it’s low-blood-pressure yen (sub-90) or hypertensive yen (160+), both damage economic health — and that has real implications for investors too. Finding the “normal range” for the Japanese economy feels increasingly urgent.
90円以下の低血圧も、160円以上の高血圧も、結局は経済の健康を損なうという点が投資の世界においても示唆するところが大きいです。どちらか一方に偏らない「正常血圧」を見つけることが、日本経済の急務であることを認識させられますね。
Currency is a country’s bloodstream, after all. Stagnation is bad, and so is constant outflow.
通貨は国の血流だからな。滞っても良くないし流出し続けても良くない。
Guess we all need to start drinking sesame barley tea. (A brand of sesame barley tea — “goma mugi-cha” — is widely advertised in Japan as helping to maintain healthy blood pressure.)
みんなで胡麻麦茶飲まんとな

My take

Love the analogy. My only complaint is that, like blood pressure, nobody ever tells you the numbers are moving until it's already a crisis.
