Bloomberg's most accurate dollar-yen forecaster has predicted the pair will reach 170 by 2027, a move that could ripple through cryptocurrency markets via the yen carry trade. The forecast, issued this week, underscores the ongoing divergence between Japan's ultra-loose monetary policy and tightening elsewhere.
A 170 yen dollar by 2027
The call comes from Bloomberg's top-ranked dollar-yen forecaster, who has a track record of nailing the pair's direction. The prediction implies further depreciation of the yen against the greenback, building on a slide that's already been dramatic. Right now the pair trades around 155, so a move to 170 would mean roughly a 10% additional drop.
That kind of move isn't the base case for most analysts, but the forecaster's methodology weights recent policy divergence heavily. Japan's central bank remains the outlier among major economies, keeping rates near zero while the Fed and ECB hold elevated levels. The gap fuels the yen's weakness.
The carry trade's crypto link
For crypto markets, the yen carry trade is the direct channel. Traders borrow yen at rock-bottom rates, convert to dollars or other currencies, and buy higher-yielding assets — including bitcoin and ether. The strategy profits from both the interest rate differential and any further yen depreciation.
A weaker yen effectively boosts the dollar-denominated returns on those crypto positions when converted back. That's been a tailwind for leveraged crypto positions this year. But the trade works in both directions. If the yen suddenly strengthens — say, on a surprise BOJ intervention — those carry trades can unwind fast, triggering a sell-off in risk assets.
What traders are watching
The Bloomberg forecaster's prediction adds weight to the view that the yen's slide has further to run. That could encourage more carry trade flow into crypto, especially as other yield sources shrink. But it's a fragile equilibrium. The Bank of Japan has already stepped into the market twice this year, and another intervention at 160 or 165 can't be ruled out.
Some traders are hedging by taking positions in yen-denominated stablecoins or using futures to lock in rates. The key question is whether the BOJ blinks before 170. The forecaster's model says no — not anytime soon. But central bank moves are notoriously hard to predict, and the stakes for crypto are real.
For now, the carry trade keeps humming. The next big test comes when Japan releases its next inflation data later this month. If core inflation ticks up, the BOJ may face pressure to adjust. Until then, the yen's path points lower — and crypto markets are along for the ride.
