The yen reached near its strongest levels in seven months on Monday as traders adjusted positions ahead of this week’s central bank decisions, even though the interest rate gap between the US and Japan is expected to stay unchanged. The dollar-yen pair (USD/JPY) traded at 154.20 during European trading, up 0.44% for the day, after briefly testing ¥155 as New York markets opened. This move reversed some of Friday’s losses but maintained the pair’s broader recovery, which began in early September when USD/JPY surged 2% in a single session to 155.28—the firmest level since August 3.
Three key factors have driven the yen’s strength this month, none of which involves the interest rate gap. Market expectations of further Bank of Japan (BoJ) tightening, the unwinding of carry trades, and signs of Japanese investors repatriating assets have all supported the currency’s rebound, despite the US 10-year Treasury yield recently surpassing 5%. Both central banks will act this week: the Federal Reserve meets on Wednesday, with a 25-basis-point hike fully priced in at 90%, while the BoJ is expected to raise rates by the same amount on Friday—its first increase since April 1995.
The arithmetic behind this week’s decisions does not alter the yield gap. The Fed’s midpoint currently stands at 3.625%, and a hike would lift it to 3.875%. If the BoJ raises its rate to 1.25%, the gap would widen to roughly 262 basis points—the same level as before. This means the yen’s movement has been driven by capital flows rather than economic fundamentals.
This week’s policy decisions will reveal which central bank’s trajectory markets trust more. The Fed is hiking rates amid 3.4% headline inflation, with traders anticipating four additional increases by mid-2027. Meanwhile, the BoJ is raising rates while still describing its policy as “below neutral,” signaling further tightening is likely. This divergence may matter more than the differential itself.

Carry Trades Unwind Fueling Yen Surge
The yen’s recovery this month has been sharp but inconsistent. After hitting a near seven-month low on September 8, the currency rebounded as traders exited carry trades, borrowing yen at near-zero rates, converting to dollars, and betting on higher-yielding assets. With the BoJ now moving toward a 1.25% policy rate, the cost of funding these trades has risen, forcing unwinds that buy yen and accelerate the move. Japan’s ¥15.4 trillion intervention in the summer, its largest ever, also signaled a policy shift, with the US participating by purchasing yen alongside Tokyo.
Technically, the dollar remains capped beneath its 20-day exponential moving average at 156.69, a level that has repelled every rebound attempt. The MACD stands at -0.814, the relative strength index (RSI) at 33.848, and the Williams %R at 81.530, all indicating oversold conditions on shorter timeframes. Monday’s bounce reflected this, but the underlying trend remains bearish for the dollar.
The next critical levels are ¥155 and ¥156.69. A break above ¥155 could open the door to ¥157, but the 20-day EMA remains the primary resistance. Below that, the pair may retest its September 8 low near 154.00, with longer-term support around ¥152, a level it has not held meaningfully since January.
Fed and BoJ Moves Could Shift Markets
This week’s decisions will determine whether the yen’s recovery continues or stalls. While the Fed’s move on Wednesday is fully priced in, the guidance will matter more than the hike itself. A signal of further tightening could push USD/JPY back toward 156.69, whereas a dovish tone might allow the yen to extend its gains into Friday’s BoJ meeting. The Japanese central bank’s decision carries the most uncertainty: a hike with clear forward guidance could sustain the yen’s strength, while ambiguity could trigger a pullback.

The market now awaits Wednesday’s Fed decision and Friday’s BoJ move. Until then, USD/JPY remains confined to a tight range, constrained by technical levels and positioning ahead of the two events.
Structural Shifts Reshape Yen’s Long-Term Outlook
The yen’s recovery has relied on two structural shifts: the unwinding of carry trades and the repatriation of Japanese capital. The mechanics of the carry trade, borrowing yen at near-zero rates, converting to dollars, and investing in higher-yielding assets, have long acted as a bet against the yen. However, with the BoJ now targeting a 1.25% policy rate, the cost of funding these positions has risen sharply.
Traders, facing mounting losses, have closed positions, creating a cycle of yen buying. This became evident on September 3, when USD/JPY dropped more than 2% in a single session, the largest intraday move since early August. Japan’s ¥15.4 trillion intervention, the largest in its history, further accelerated the shift, as traders reassessed risks from short yen positions.
The second factor has been domestic investors bringing capital back home. Japanese life insurers, pension funds, and institutional investors hold trillions in overseas assets, many hedged against currency risk. As Japanese bond yields have risen toward competitive levels, the appeal of holding foreign assets has diminished. Higher domestic yields reduce the benefits of hedged foreign bonds, while increased hedging costs on dollar assets have made repatriation more attractive. This structural flow contrasts with past yen rallies, which were often driven by speculative positioning. The current move appears more lasting, reflecting a permanent change in investor behavior rather than a temporary reversal of trade flows.
