Have you ever wondered what happens when one of the biggest “free money” tricks in global finance starts to fall apart? Right now, in late 2025, that’s exactly what’s playing out with something called the yen carry trade—and it’s sending ripples straight through markets, including Bitcoin.
I’ve been following these kinds of macro shifts for years, and this one feels particularly tricky. On one hand, it’s causing some real short-term headaches for risk assets like crypto. On the other, it might just be setting the stage for something bigger down the line. Let’s break it down step by step, without all the jargon overload.
The Yen Carry Trade: Global Liquidity’s Silent Engine
For decades, savvy investors have been borrowing money in Japanese yen at rock-bottom rates—sometimes near zero or even negative—and pouring it into higher-yielding stuff abroad. Think U.S. Treasuries, stocks, or even cryptocurrencies. The beauty of it? You pocket the difference without much risk, as long as the yen stays weak and rates don’t move.
It’s been like an invisible pump injecting trillions into global markets. Estimates vary, but some analysts peg the total exposure in the hundreds of billions, if not more when you factor in derivatives. No wonder everything from tech stocks to Bitcoin has felt that extra lift over the years.
But things change. Japan, dealing with its own inflation pressures and a weakening currency, has been gradually hiking rates. Meanwhile, the Federal Reserve has been cutting. That interest rate gap—the heart of the trade—is shrinking fast.
When the spread narrows and the yen starts strengthening, the math flips. Suddenly, holding those positions gets expensive, and investors rush to unwind.
We’re seeing exactly that now. Japanese bond yields are hitting multi-decade highs, forcing borrowers to sell off assets to repay yen loans. It’s a classic liquidity squeeze, pulling money out of riskier investments.
Why This Hits Bitcoin Especially Hard
Bitcoin isn’t just another asset—it’s often the canary in the coal mine for liquidity changes. As a highly leveraged, speculative play, it amplifies both ups and downs in global funding conditions.
Think about it: Crypto markets thrive on easy money. When carry trades provided endless cheap yen funding, a lot of that flowed into leveraged Bitcoin positions. Now, with the unwind accelerating, we’re seeing forced selling. Liquidations spike, prices dip, and volatility reigns.
In recent weeks, Bitcoin has hovered around $87,000 to $88,000, down from highs above $90,000 earlier in the month. Some sessions have seen sharp drops, with billions in positions wiped out. It’s not panic territory yet, but it’s uncomfortable.
- Forced deleveraging from carry unwind participants
- Rising funding costs eating into profits
- Broader risk-off sentiment spilling into crypto
- Amplified by Bitcoin’s inherent leverage in derivatives markets
I’ve noticed this pattern before—in previous unwind episodes, Bitcoin often leads the pain but also recovers sharply when liquidity returns. The question is timing.
The Bank of Japan’s Role in the Shift
Japan’s central bank has been ultra-accommodative for ages, keeping rates low to stimulate their economy. But persistent inflation and a yen that’s weakened significantly have changed the calculus.
Rate hikes started earlier in the cycle, but the momentum built through 2025. Bond yields surging to levels not seen since the 2000s signal a real policy pivot. Speculators who were short the yen are covering, adding fuel to the appreciation.
This isn’t sudden chaos like some past events—much of it seems priced in. Positions have adjusted gradually. Still, even a controlled unwind can create waves, especially in interconnected markets.
Perhaps the most interesting aspect is how this contrasts with other funding currencies. The Swiss franc is emerging as an alternative, but nothing matches the scale of the yen’s historical role.
Federal Reserve’s Counterbalance: Easing on the Horizon
Here’s where it gets nuanced. While Japan tightens, the Fed has been in cutting mode. Multiple reductions this year, ending quantitative tightening, and signals of more accommodative policy ahead.
Lower U.S. rates mean cheaper dollar borrowing, potentially offsetting some yen pressure. Plus, if the Fed resumes balance sheet expansion or hints at liquidity injections, that could flood markets again.
In my view, this divergence creates a tug-of-war: short-term drain from carry unwinds versus longer-term boost from Fed easing. Bitcoin, sensitive to both, sits right in the middle.
The Fed’s shift could provide the fuel for risk assets to rebound strongly once the unwind dust settles.

Recent repo operations and balance sheet dynamics suggest reserves are ample, but any hint of expansion would be hugely bullish.
Historical Patterns and Bitcoin’s Resilience
Looking back, Bitcoin has weathered similar storms. Drawdowns over 50% aren’t rare, but it hasn’t closed below key fundamentals like mining costs for long.
The electrical cost of production acts as a rough floor—miners won’t sell below breakeven indefinitely. In volatile periods, we’ve seen prices respect that level before bouncing.
| Period | Major Event | Bitcoin Drawdown | Recovery Time |
| 2024 Unwind | Initial BOJ Hike | ~25-30% | Several months |
| Late 2025 | Ongoing Unwind | 10-20% so far | Ongoing |
| Post-Halving Cycles | Liquidity Shifts | Varies | Strong rebounds |
These episodes remind us: volatility is part of the game. But structural trends—like institutional adoption and supply constraints—tend to win out.
What Could Happen Next for Bitcoin Prices
Short term, more choppiness seems likely. If the unwind intensifies around upcoming policy meetings, we could test lower supports—maybe mid-80s or even below.
But flip the script: Once deleveraging exhausts itself, fresh liquidity from the Fed side could spark a relief rally. Analysts are mixed—some see $100,000+ by year-end if easing dominates, others warn of sub-$80,000 if risk aversion lingers.
- Monitor yen strength and Japanese yields for unwind intensity
- Watch Fed communications for balance sheet hints
- Track Bitcoin leverage and liquidation levels
- Consider mining cost metrics as potential floors
Personally, I lean toward caution near term but optimism longer. These shakes often create better entry points.
Broader Implications for Crypto and Risk Assets
This isn’t just a Bitcoin story. Equities, emerging markets, even gold feel the pinch when carry flows reverse. Crypto’s leverage makes it front-line, but the effects cascade.
On the bright side, a world with normalized rates might mean healthier growth eventually. No more relying on endless cheap funding glitches.
Still, transitions are messy. 2025 has been full of them—from ETF inflows to regulatory shifts—and this unwind adds another layer.
Final Thoughts: Navigating the Turbulence
If there’s one takeaway, it’s that macro matters more than ever for Bitcoin. Ignore the plumbing at your peril—these carry trades and policy divergences drive big swings.
Right now, pressure feels real, with prices reflecting that liquidity pullback. But history shows these periods pass, often leading to stronger legs up when conditions stabilize.
Whether you’re holding through the noise or waiting for clearer skies, staying informed on these cross-currents is key. In my experience, the best opportunities come after the forced selling ends.
Who knows—maybe this unwind is the last big hurdle before Bitcoin pushes toward those loftier targets we’ve been hearing about. Or perhaps it drags a bit longer. Either way, it’s fascinating to watch unfold.
