Dollar Briefly Drops to 152 Yen Range — 5ch Debates What Exchange Rate Would Be Ideal

From our other sites

The story

On the morning of September 8, 2026, Reuters flashed a report that the dollar-yen exchange rate had briefly fallen to the 152 yen range on the foreign exchange market. The sudden swing came amid a yen-weakening trend from levels of around 110 yen to the dollar just a few years earlier, and on 5ch’s Newsflash+ (Nyusu Sokuho+) thread, posters expressed surprise, asking “Did all this movement really happen from mere verbal intervention (jawboning), without any actual buying/selling?” A poll-style post asking “Where should the ideal exchange rate be?” drew a wide range of answers, from the 90s to the 170s yen range, and lively discussion also broke out over how a stronger yen would affect prices, home appliances, and NISA (Japan’s tax-free investment account) assets.

Bessent just gave it a quick 'lizard check' (5ch slang for a mere token warning glance) and it had this much effect
Meanwhile the tens of trillions of yen in actual intervention did nothing

Didn't they just lock in their profits? (´・ω・`)

Re: #38
They converted to yen right at the peak, so that's a win for them

Re: #38
Wasn't Takaichi the reason for the weak yen in the first place?
Before the Takaichi administration it was around 147 yen to the dollar

Which level would be ideal?

・170s yen
・160s yen
・150s yen
・140s yen
・130s yen
・120s yen
・110s yen
・100s yen

Re: #47
Personally I've got zero dollar positions, so even 50 yen would be fine by me (´・ω・`)

125 yen was said to be the 'Kuroda Line' that (then-BOJ governor) Kuroda was determined to defend at all costs

Re: #47
I'd want somewhere between 110 and 120 yen, but the auto industry would never stand for it

Will a 200,000-yen iPhone drop to around 150,000 yen once the yen strengthens?
98AnonymousSep 8, 2026 11:40
Re: #78
When do you think they actually buy the parts?
159AnonymousSep 8, 2026 11:44
Re: #78
Over 70% of the iPhone's manufacturing process happens in Japan, you know?
Between the strong yen/weak dollar and inflation, it won't even be a wash — prices will actually go up
88AnonymousSep 8, 2026 11:40
I cashed out my overseas NISA

Re: #88
Isn't that just the confirmation screen?
111AnonymousSep 8, 2026 11:41
What happens if prices stay high even as the yen strengthens?
128AnonymousSep 8, 2026 11:42
Re: #111
Basically, prices should come down
136AnonymousSep 8, 2026 11:42
Re: #111
Actually, companies probably won't lower prices once they've already raised them
161AnonymousSep 8, 2026 11:44
Re: #111
If the yen strengthens, imported goods will get cheaper lol
120AnonymousSep 8, 2026 11:41
Will products that went up in price because of the weak yen come back down?
131AnonymousSep 8, 2026 11:42
Re: #120
They'll cook up some excuse and just not lower them
154AnonymousSep 8, 2026 11:43
Re: #120
Apparently it takes six months to a year for exchange rate moves to show up in prices
So give it at least six months
129AnonymousSep 8, 2026 11:42
What's going to happen to my NISA?
151AnonymousSep 8, 2026 11:43
Re: #129
Just black out for 30 years — actually, keep buying more
160AnonymousSep 8, 2026 11:44
Re: #129
Just sell now and buy back once the yen strengthens
139AnonymousSep 8, 2026 11:43
If this is really from jawboning alone… maybe actual intervention is happening too
195AnonymousSep 8, 2026 11:45
Re: #139
Bessent probably doesn't want any more selling at this point lol
235AnonymousSep 8, 2026 11:47
Re: #139
That's my read on it too
142AnonymousSep 8, 2026 11:43
Just four years ago it was in the 110s, so I'd be happy if it went back that far
Stocks are still holding up strong though, so a lot of people probably won't have much to complain about going forward
Can't speak for anyone dollar-cost averaging in USD though
168AnonymousSep 8, 2026 11:44
Re: #142
Well, 100 yen would be ideal — it's easy to do the math with that
228AnonymousSep 8, 2026 11:46
Re: #142
If we can get the exchange rate down to that level without triggering high inflation, keep stock prices up, improve the birth rate, and raise food self-sufficiency, then even I'll admit Takaichi did a good job
146AnonymousSep 8, 2026 11:43
Sorry, could you push it back up to 160 for a bit? I need to unwind some positions
163AnonymousSep 8, 2026 11:44
Re: #146
You'll have to wait another 15 years for that…
186AnonymousSep 8, 2026 11:45
Re: #146
Got it
We'll push it back to 160 starting at 15:30, so get out then

Background and Key Points of This Discussion

The dollar-yen exchange rate often swings sharply in a short span due to a mix of factors — jawboning remarks aimed at the markets from the U.S. Treasury Secretary, speculation about government intervention, and more. This drop to the 152 yen range may likewise have come not from large-scale actual intervention but from verbal remarks alone, as several posters in the thread pointed out. Opinions in the thread were split on “what level would be ideal,” ranging from hopes for a return to the 110s to a preference for keeping things as they are. One easily misunderstood point: even as the yen strengthens, it typically takes several months to a year for that to be reflected in import prices, so prices that have already risen won’t necessarily drop right away just because of currency gains. It’s also worth noting, as a practical matter, that products like the iPhone — which go through many manufacturing steps within Japan — won’t necessarily get cheaper from yen strength alone.
