Have you ever watched a currency sit at a discount for so long that people stop treating the discount as a reason to buy? That is roughly where the Japanese yen has lived. It has looked cheap on valuation screens for years, and still the path of least resistance often pointed toward more weakness rather than a clean rebound. I keep coming back to that tension because markets rarely stay that inconsistent forever. When cheapness, policy, and capital flows start pointing in the same direction, the story changes even if the headline rate still looks unfriendly.
Why The Cheap Yen May Finally Matter
A Singapore-based research team argued this week that the yen is among the most undervalued major currencies and that a turning point is getting closer. The interesting part is not the valuation call itself. Plenty of desks have said the same thing. The interesting part is the claim that domestic policy and investor behavior may finally give that cheapness some teeth.
Unlike some other Asian currencies, a soft yen has not automatically produced relief. Depreciation pressure kept showing up even after the currency looked stretched. That is why so many traders treated yen strength as a squeeze, not a regime shift. In my view, that habit is now the risk. If the next bout of yen buying is driven by policy and repatriation rather than a one-week squeeze, the old playbook gets expensive fast.
Cheap valuation has done little to ease depreciation pressures on its own. Support has to come from policy and flows, not from a chart looking oversold.
Intervention Bought Time, Not A New Trend
There was a rare coordinated push from Japanese and U.S. authorities after the yen jumped to multi-decade extremes in July. Speculative short positions got squeezed. Officials made it obvious they were uncomfortable with disorderly weakness. That episode mattered. It also did not settle the medium-term debate.
Intervention can scare leveraged money for a while. It cannot permanently rewrite the rate gap between Tokyo and other major central banks. Without a change in domestic policy, the yen often drifts back toward the same funding-currency role that made it popular in the first place. I have found that markets remember the squeeze and forget the follow-through. That is usually when the next crowded short rebuilds.
The research note put it plainly: intervention alone is unlikely to deliver a sustained recovery unless domestic policy changes arrive as well. That support, the team said, may finally be emerging. That is the hinge of the whole argument.
The Policy Gap Is Narrowing, Not Vanishing
The Bank of Japan looks more willing to normalize at a faster clip than it did during the long years of ultra-easy settings. That does not mean Tokyo is about to outhawk Washington in the near term. It does mean the old, yawning policy gap may stop widening and start to compress at the margin.
For currency markets, direction often comes from the change in the gap, not from the absolute level of rates. A still-easy Japan can support a firmer yen if the rest of the world is easing, pausing, or simply looking less aggressive. Perhaps the most interesting aspect is how little the market needs in order to reprice the yen if positioning is still skewed the other way.
That is why the forecast revision matters more as a signal than as a pinpoint target. The same research desk moved its end-2026 dollar-yen view to 155 from 160, and pointed to 150 by the end of 2027. Nobody should treat those numbers as destiny. They do tell you the house now expects valuation and policy to pull in the same direction rather than fight each other.
| Horizon | Prior View | Updated View |
| End-2026 USD/JPY | 160 | 155 |
| End-2027 USD/JPY | Not the focus | 150 |
| Near-term policy | Slow normalization | Faster, still not outhawking peers |
| Key driver shift | Rate gap dominates | Valuation plus flows gain weight |
Valuation Stops Being Background Noise
Deep undervaluation is a lazy argument when carry is still paying people to stay short. It becomes a better argument when carry fades and domestic investors start looking homeward. The note’s core claim is that the yen’s cheapness can become a more meaningful driver of performance as policy and flow dynamics turn supportive.
I tend to agree with the sequencing. Valuation is the dry wood. Policy is the match. Flows are the wind. One without the others can sit there for a long time. Put all three together and the move can look obvious only after it has already started.
That is also why comparing the yen with other cheap currencies can mislead. A currency can be undervalued and still weaken if residents keep exporting capital and foreigners keep using it as funding. The yen has been that case study. The question now is whether Japanese investors begin to treat domestic assets as competitive again.
Portfolio Flows Could Become The Quiet Catalyst
Japanese households and institutions have spent years hunting yield abroad. That habit helped keep the yen soft even when tourists and exporters told a different story. A meaningful rotation back into domestic assets would be a powerful tailwind. Not a one-day headline. A multi-quarter change in the plumbing.
The research team expects further policy initiatives aimed at encouraging domestic investment by Japanese investors. If those initiatives land, the flow story stops being theoretical. You do not need a sudden patriotic stampede. You need a smaller deficit on the portfolio side and a less one-way bid for foreign bonds and equities.
- Less relentless buying of overseas assets by Japanese investors
- A narrower policy gap with other major central banks
- Official discomfort with disorderly yen weakness already on display
- Valuation that leaves less room for the old trend to look cheap and easy
None of those items guarantees a straight line to a stronger yen. Together they raise the cost of treating every dip as an invitation to rebuild the same short.
Carry Trades Will Not Disappear Overnight
Here is the part that often gets skipped in bullish yen notes. Carry is a habit. It survives longer than fair-value models suggest because it pays people to wait. Even if the yen starts to look less like the automatic funding currency, someone else can take that role.
The same desk expects the Swiss franc to remain the preferred funding currency among investors if the yen firms. That view rests on an expectation that Swiss policy rates stay at 0% through at least year-end, preserving the franc’s low-yielding appeal. In plain language: the market may rotate the funding leg rather than shut the carry machine down.
That distinction matters for risk management. A stronger yen does not automatically mean calmer cross-asset markets. It can mean the pressure moves. Equity, credit, and emerging-market trades that were funded in yen can be re-funded elsewhere. The unwind can still sting. It just may not look like the textbook yen squeeze people keep rehearsing.
What A Turning Point Would Actually Look Like
Turning points in currencies are messy. They rarely arrive as a single press conference. They show up as a cluster of smaller changes that make the old trade less comfortable.
- Officials keep signaling that excessive yen weakness is a policy problem, not a free lunch.
- Domestic rate guidance stops sounding like a promise of endless patience.
- Japanese investors slow the pace of overseas allocation even slightly.
- Dollar-yen fails to hold the highs that used to attract fresh shorts.
- Option markets start charging more for yen upside instead of treating it as a freak event.
If those boxes start getting ticked, the market does not need a heroic Japanese tightening cycle. It needs enough doubt to stop treating 160-plus as the default destination.
Why The Dollar Side Of The Pair Still Matters
It is easy to write a yen story as if Japan were the only actor on the stage. Dollar-yen is still a two-sided price. If U.S. policy stays restrictive for longer than markets expect, the yen can look cheap and still struggle. If U.S. growth cools and rate-cut odds rise, the same cheap yen can move faster than the domestic news flow seems to justify.
That is why the research team’s caution about the Bank of Japan not outhawking the Federal Reserve in the near term is useful. The bull case for the yen is not a Japanese rate shock. It is a narrower gap plus a valuation magnet plus a possible change in resident flows. Mix those with a slightly less dominant dollar and the path toward 155, then 150, becomes less heroic than it sounds today.
In my experience, pairs like this punish people who pick one narrative and ignore the other. The yen can be turning and still have ugly weeks if the dollar catches a bid. The point is not to pretend those weeks will vanish. The point is that pullbacks may start looking like opportunities rather than confirmation of the old downtrend.
Practical Ways To Think About Positioning
This is not trading advice. It is a way to organize the debate so you do not get hypnotized by a single forecast print.
First, separate the squeeze from the trend. A coordinated official response can lift the yen quickly. A trend needs policy and flows. If you only trade the squeeze, you will keep fading strength that later refuses to fade.
Second, watch Japanese investor behavior more closely than another round of fair-value charts. Valuation is already well known. Flows are the missing piece. A modest home bias would do more for the currency than another speech about undervaluation.
Third, keep an eye on the next funding currency. If the franc absorbs the carry role, some of the market’s yen-short reflex may fade even before Japanese rates look “normal” by global standards.

The Risks That Could Keep The Old Story Alive
A turning point is a claim, not a promise. Several things could keep the yen cheap and unloved.
Japanese growth could stay soft enough that normalization remains cautious. Inflation could cool and reduce the urgency to move. Overseas yields could stay attractive enough that domestic investors keep sending money abroad. The dollar could catch another growth or rate surprise. Any one of those would give the old short a new lease on life.
There is also the political layer. Currency officials can dislike weakness and still hesitate if a stronger yen arrives faster than exporters can digest. Markets have seen that hesitation before. It is one reason intervention often looks dramatic in the moment and incomplete three months later.
The direction looks more supportive for the yen, but support is not the same thing as a one-way rally.
A Longer View Through 2027
The 2027 marker at 150 is less about precision and more about the shape of the path. It says the desk no longer wants to anchor the medium-term map around a structurally weaker yen as the base case. That is a meaningful shift in tone even if the next fifty points take the scenic route.
Think of it as a change in the burden of proof. For a long time, bulls had to explain why the yen should rise against a wide rate gap and persistent capital outflow. If policy and flows turn, bears will have to explain why a deeply cheap currency should keep making new lows.
That swap in the burden of proof is often how turning points feel from the inside. The chart does not look different on day one. The questions people ask in morning meetings do.
What Readers Should Take Away
The yen can be undervalued for a long time. That fact alone never guaranteed a rebound. What may be changing is the supporting cast around that valuation. Officials have already shown they care about disorderly weakness. Policy in Japan looks less frozen. Domestic investors may be nudged toward home assets. And if the yen does firm, carry demand may simply migrate toward another low-yielding currency rather than vanish.
I would not dress that up as certainty. Markets have a talent for stretching a crowded story past the point where it looks rational. Still, the setup is less one-sided than it was when cheapness was just a trivia fact on a valuation scorecard.
If you follow currencies for a living, or even if you only watch them because they leak into stocks and bonds, this is the sort of shift worth keeping on the desk. Not because 155 is magic. Because the ingredients that kept the yen weak are no longer lining up as neatly as they used to. And once that alignment breaks, the market has a habit of rediscovering a currency it had filed under “permanently cheap.”
