JPMorgan: Yen Strength May Accelerate Recovery in Tokyo AI and Semiconductor Stocks
nashnova research
JPMorgan argues yen strength will push down Japan's long-end rates, opening an early valuation-repair window for Tokyo-listed AI and chip stocks — but Saxo Bank warns the same rally could trigger a global unwind of leveraged carry trades, and the dividing line is whether the yen stops near 155.
How fast has the yen moved?
The yen surged from above 160 per dollar through the 155 support level, touching 152.89 intraday — a roughly seven-month high.
U.S. Treasury Secretary Scott Bessent publicly stated he is actively pushing for a stronger yen, declaring "I'm the house now" and warning yen shorts not to bet against him.
This means → yen appreciation is no longer purely market-driven; there is an explicit U.S. policy signal behind it.
Why are hedge funds and Japanese retail on opposite sides?
Hedge funds are aggressively long the yen, betting it breaks 150 by year-end; some targets reach 140.
Japanese retail investors are doing the opposite — adding to short positions — creating an extreme institutional-vs-retail divergence.
The overnight index swap (OIS) market — a rate contract that prices in central-bank moves — shows traders have fully priced in a 25-basis-point hike on September 18.
How much earnings cushion do exporters have left?
At 153.25, the yen has already breached the 153.90 average FX assumption disclosed by roughly 220 Topix-component companies — the safety buffer they built in is being eaten away.
Nomura estimates that FX moves contributed about ¥830 billion to operating-profit growth for ~190 companies in Q1, exceeding the combined contribution of price hikes and volume gains.
In plain terms = much of the strong profit growth exporters reported in recent quarters came from a weak yen; once that tailwind dies — or reverses — headline earnings growth drops with it.
Who gets sold first, and who gets bought?
Japanese auto stocks are down 8% month-to-date; exporters broadly are being dumped — "the weak-yen earnings boost is fading, and FX may even turn into a headwind."
Short-term money is rotating into domestic-demand sectors that benefit from yen strength and lower rates, such as real estate and construction.
Within chip equipment, a split is emerging: Tokyo Electron and Screen Holdings sell in yen with limited FX exposure, while Advantest, Lasertec, and Disco book revenue in dollars — currency swings hit their earnings more directly.
What exactly are JPMorgan and Saxo Bank arguing about?
JPMorgan's chain: stronger yen → lower long-end Japanese rates → AI and semiconductor stock valuations start repairing earlier, and real-estate stocks benefit too.
Saxo Bank's chain: a rapid yen spike → the carry trade (borrowing cheap yen to buy higher-yielding assets) unwinds → the most liquid, most profitable positions get sold first — which includes AI chip stocks and REITs.
This reflects how the same variable — yen appreciation — produces diametrically opposite conclusions depending on the transmission channel you focus on.
Stronger yen: medicine or poison for Tokyo tech stocks?
BULL
Lower rates open room
A stronger yen pushes down long-end rates, opening a valuation-repair window for rate-sensitive sectors earlier.
155 is the safe line
MUFG expects the yen to stabilize near 155, where manufacturers maintain competitiveness and AI demand plus pricing power support earnings.
BEAR
Carry-trade unwind risk
Years of cheap-yen borrowing to fund risk assets unwinds — the most liquid holdings get sold first.
Earnings forecasts at risk
Sustained appreciation erodes exporter profits; FX flips from tailwind to headwind, and earnings estimates may be cut.
In plain terms = both sides have a point — the key variable is the speed and endpoint of yen appreciation: a gradual drift to 155 favors JPMorgan's thesis; a rapid break below 150 amplifies the unwind risk Saxo Bank is flagging.
What to watch next?
The 155 level: MUFG expects the yen to hold here; if it does, exporter earnings pressure stays manageable. If it breaks, the cushion is gone.
The Bank of Japan's September 18 rate decision and post-meeting forward guidance — this will reset the market's pricing of the rate path ahead.
This means → the yen's trajectory and the central bank's language over the next few weeks are the critical window for resolving the JPMorgan-vs-Saxo divergence.
