The Yen At A 40-Year Low: The World’s Cheapest Currency And The Trade Crowding Into It.
The yen slid past 161 to the dollar — its weakest in 40 years, through the level Japan defended just two months ago. The carry trade (borrow cheap yen, buy dollars) is in full effect, and history says crowded carry trades end suddenly.

Past 161 to the dollar — through the level Japan defended in April and May.
What’s Happening
The yen is at its lowest against the dollar in four decades — about 161 late Thursday — having blown through the levels where Japanese authorities intervened in April and May. The drivers: U.S. rates far above Japan’s (making it profitable to borrow yen and park in dollars), a hawkish Fed, war-era haven demand for dollars, and worries about Japan’s fiscal expansion. Speculators are short; Pimco calls the yen undervalued ‘by most measures’ but stays neutral; one strategist says 166–167 is where they’d start buying.
Global managers aren’t bailing — they’re holding positions and, in some cases, using the cheap yen to buy Japanese exporters and banks, which earn wider margins as the Bank of Japan slowly raises rates.
Crowded carry trades don’t end gently. The plan isn’t to predict the unwind — it’s to be the buyer with cash when it happens.
Why A Retiree Should Care
Three reasons. First, the carry trade is the market’s most crowded funding trade, and when crowded carry trades unwind — as in August 2024 — the deleveraging hits everything, including U.S. stocks, for a few violent days. Second, a 40-year-cheap yen is quietly why Japanese equities keep working: exporters earn dollars and pay costs in yen. Third, it’s a live case study in why we don’t bet client money on currency direction — even Pimco won’t call this one.
The disciplined takeaways: international diversification should be deliberate about currency (hedged where the income matters), and a violent carry-unwind day is a buying opportunity for the prepared, not a reason to sell.
The Planning Read
We don’t trade FX. We hold international exposure sized so a yen shock is a headline, not a plan change, keep the gold sleeve as the all-weather currency hedge (gold made another high in dollar terms at $4,112), and keep cash ready for the day the crowded trade unwinds and quality goes on sale for 72 hours.
What This Means For The Book
Currency calls don’t belong in a retirement book — when Pimco itself is neutral on the yen, we’re not pretending to know better. What we do instead: size international holdings so an FX shock never forces a decision, hold gold as the currency hedge that needs no forecast (it made a new dollar high at $4,112 this week), and keep short-Treasury dry powder for the day the crowded carry trade unwinds and drags quality assets down with it for a few days. That’s not a prediction — it’s a standing order to be the calm buyer.
