The Yen’s Comeback Starts Here—and it Seems the COT Knew First1. Introduction: A Market Everyone Gave Up On
For a while, the Japanese Yen looked like a lost cause. After topping out in early 2021, Yen futures (6J1!) began an unrelenting slide, shedding value week after week like an old coat in spring. Traders stopped asking, “Where’s support?” and started asking, “How low can it go?”
The macro backdrop didn’t help. The Bank of Japan clung to ultra-loose monetary policy, even as the Fed hiked aggressively. Speculators piled on shorts. The Yen was a one-way ticket down, and no one seemed interested in punching the brakes.
But beneath that apathy, a quieter shift was underway. While price kept bleeding, trader positioning began to hint at something different—something the chart didn’t show yet. And if you were watching the Commitments of Traders (COT) report closely enough, you might’ve seen it.
2. The COT Trend That No One Was Watching
The COT report isn’t glamorous. It’s slow, lagging by a few days, and rarely makes headlines. But for those who track what the big players are doing—those large enough to be required to report their positions—it’s a treasure trove of subtle clues.
One of those clues is Total Reportable Positions. This metric tells us how active large market participants really are—regardless of whether they’re long or short. When that number is dropping, it suggests the “big dogs” are losing interest. When it starts climbing again? Someone’s gearing up to play.
From 2021 through most of 2024, Total Reportable Positions in 6J were in a steady decline—mirroring the slow death of the Yen's bullish case. But in late 2024, something changed. Using a simple linear regression channel on this COT data, a clear breakout emerged. Positioning was picking up again—for the first time in nearly three years.
And it wasn’t just a bounce. It was a structural shift.
3. Did Price Listen?
Yes—and no. Price didn't immediately explode higher. But the structure began to change. The market stopped making new lows. Weekly closes began to cluster above support. And importantly, a Zig Zag analysis started marking a pattern of higher lows—the first signs of accumulation.
Here’s where the chart really gets interesting: the timing of the COT breakout coincided almost perfectly with a key UFO support at 0.0065425—a price level that also marked the bottom in COT Traders Total Reportable Longs. This adds a powerful layer of confirmation: institutional orders weren’t just showing up in the data—they were leaving footprints on the chart.
And above? There’s a UFO resistance level at 0.0075395. If the Yen continues to climb, that could be a significant price level where early longs may choose to lighten up.
4. The Contract Behind the Story
Before we go deeper, let’s talk about what you’re actually trading when you pull the trigger on Yen Futures.
The CME Japanese Yen futures (6J) contract represents 12.5 million Japanese Yen, and each tick move—just 0.0000005 per JPY—is worth $6.25. It’s precise, it’s liquid, and for traders who like to build macro positions or take advantage of carry flows, it’s a staple.
As of May 2025, margin requirements hover around ~$3,800 (Always double-check with your broker or clearing firm—these numbers shift from time to time.)
But maybe you’re not managing seven-figure accounts. Maybe you just want to test this setup with more flexibility. That’s where the Micro JPY/USD Futures (MJY) come in.
Contract size: 1/10th the size of 6J
Tick move: 0.000001 per JPY increment = $1.25
Same market structure, tighter margin requirement around ~$380 per contract
Important note: The COT report aggregates positioning across the whole futures market—it doesn’t separate out micro traders from full-size. So yes, the data still applies. And yes, it still matters.
5. Lessons from the Shift
This isn’t about hindsight bias. The value in this setup isn’t that the Yen happened to bounce—it’s how Total Reportable Positions broke trend before price did.
Here are the real takeaways:
COT data may or may not be predictive—but it is insightful. When positioning starts expanding after a long contraction, it often signals renewed interest or risk-taking. That’s tradable information.
Technical support and resistance as well as highs and lows give context. Without them, COT breakouts can feel theoretical. With them, you have real, observable UFO levels where institutions may act—and where you can plan.
6. Watchlist Insights: Where This Might Work Again
You don’t have to wait for another yen setup to apply this framework. The same structure can help you scout for early positioning shifts across the CME product universe.
Here’s a simple filter to start building your own COT watchlist:
✅ Look for markets where:
Price has been in a long, clean downtrend (or uptrend)
Total Reportable Positions are falling—but starting to reverse
A breakout occurs in positioning trend (draw a regression channel and watch for a clean violation)
A key support or resistance lines up with recent extremes in COT positioning
Whether it's crude oil, corn, or euro FX, this template gives you a framework for exploration.
