CURRENCIESThe yen at a 40-year low
It isn't Japanese weakness: it's the distance between a Fed holding rates high and a Bank of Japan that has barely moved them.

THE NUMBER
¥163
↑ the yen's lowest against the dollar in four decades
The engine is the rate gap: the Fed pays a lot to hold dollars, the Bank of Japan almost nothing to hold yen. Money flows to where it earns more, and the yen sinks by pure financial gravity.

▼ yen at a 40-year low
For a Japanese household, everything imported (energy, food, tech) gets pricier. For a tourist with dollars, Japan has never been cheaper. Same currency, two worlds.
The yen hasn't fallen this far against the dollar since the 1980s. The cause isn't panic, it's the Fed-BoJ rate gap sustained over time.
- DEPRECIATION
- — When a currency loses value against another. It raises the cost of imports.
- IMPORTED COST
- — The inflation that enters by buying abroad with a weak currency.
QUOTE
CONTEXTA cheap yen is cheap fuel
“As long as the yen stays cheap and the rate gap stays open, the world funds itself in yen. The trouble comes the day that bet turns around.”
With the yen this weak, borrowing in yen to invest in higher-yielding assets gets very tempting. That's the carry trade, and it grows quietly.
- CARRY TRADE
- — Borrowing in a cheap currency (yen) to invest in another that yields more.
- SPREAD
- — The yield distance between two assets or two currencies.
- UNWIND
- — When a very crowded bet unravels at once and everyone runs for the exit together.
TREND
SINCE 2024The dollar's relentless climb against the yen
Two years of the yen giving ground. A sustained break past ¥160 puts Japanese intervention back on the table.
USD/JPY since early 2024. The ¥160 line marks the zone where Japan has stepped in before to slow the fall.
- INTERVENTION
- — When a central bank buys its own currency to slow its decline.
- USD/JPY
- — The cross that measures how many yen a dollar is worth.
CONTRAST
WIN / LOSEWho wins and who loses with a weak yen
WINNERS
The export side
- Japanese exporters: their goods are cheaper abroad and their dollar sales are worth more yen.
- Tourism into Japan: traveling and shopping there is a bargain with a strong currency.
- Anyone borrowing cheaply in yen to invest in higher-yielding assets.
LOSERS
The import side
- Japanese households: imported energy, food and tech all get pricier.
- The purchasing power of yen savings erodes year after year.
- The global market, if the carry trade unwinds suddenly and drags other assets with it.
A weak currency isn't good or bad on its own. It creates very clear winners and losers.
- EXPORTER
- — A company that sells abroad. A weak currency makes its goods cheaper overseas.
- PURCHASING POWER
- — How much your money can buy. It falls when imports rise.
COMPOSITION
WHY IT FALLSWhat's sinking the yen
70% of the fall is monetary policy: until the Fed cuts or the Bank of Japan hikes, gravity keeps working against the yen.
The fall doesn't come from one factor. Four forces stack up and push in the same direction.
- MONETARY POLICY
- — A central bank's decisions on rates and liquidity.
- RISK-OFF
- — A fear phase where money seeks a haven, typically the dollar.
WATCHLIST
5 KEY ETFsFive ways to track the yen
| FXY | 58 | ▼ -0.8% | Tracks the yen against the dollar. Falls because the yen falls. The direct gauge. |
| DXJ | 115 | ▲ +0.9% | Currency-hedged Japan. Wins on the weak yen: it captures the rally without the currency drag. |
| EWJ | 76 | → +0.1% | Unhedged Japan. For a dollar investor, the equity rally is eaten by the falling yen. |
| UUP | 29 | ▲ +0.3% | Dollar index. Rises from the other side of the same cross. |
| EEM | 48 | ▼ -0.6% | Emerging markets. A strong dollar squeezes them: their dollar debt weighs more. |
