If you owned Bitcoin in August 2024 you remember the day the market lost 20% in a single session for no obvious reason. There was no hack, no exchange collapse, no ETF outflow big enough to explain it. What actually happened was a Japanese interest rate decision six thousand miles away. If you don’t understand the yen carry trade, you’re missing one of the most important macro forces in your portfolio.
I watched the Fox Business segment on this earlier and it did a decent job of the mechanics. Here it is if you want the 3-minute primer — then this post fills in what happens next, especially for crypto holders.
Short answer: The Japanese yen carry trade is a strategy where investors borrow money in Japan at near-zero interest, convert those yen into US dollars (or another currency), and invest the proceeds in higher-yielding assets — US Treasury bonds, tech stocks, and increasingly, Bitcoin and crypto. It has funded trillions of dollars of global risk-asset positions. It is now unwinding as the Bank of Japan raises rates — the BOJ is expected to lift its policy rate to 1.25% at its 17–18 September 2026 meeting, with markets pricing 97% odds. Every previous BOJ hike in 2026 has coincided with a 20–31% Bitcoin drawdown.

Key takeaways
- The yen carry trade = borrow cheap in Japan, invest at higher yields elsewhere. Pocket the difference.
- BOJ policy rate is currently 1.00%. A hike to 1.25% is expected on 18 September 2026 with ~97% market odds.
- The US-Japan rate gap remains ~225–250 basis points even after the expected hike, so the trade doesn’t fully die yet — but it gets much less profitable.
- Bitcoin has fallen 20–31% after each of the last three BOJ rate hikes in 2026.
- The August 2024 unwind wiped 12% off Tokyo stocks in one day and 20% off Bitcoin, according to the Bank for International Settlements.
What is the Japanese yen carry trade?
The Japanese yen carry trade is a currency-based investment strategy that exploits the interest rate difference between Japan and the rest of the developed world.
Here’s the mechanic in plain English. A hedge fund, bank, or big institutional investor borrows money in Japanese yen from a Japanese lender at close to 0% interest. It then converts those yen into US dollars on the foreign exchange market. Finally, it invests those dollars in something that pays a much higher yield — US government bonds paying 4–5%, US tech stocks, S&P 500 futures, or in the last few years, Bitcoin.
The profit is the spread. Borrow at ~0%. Invest at ~4%. Pocket ~4% every year for as long as the trade holds up. When you multiply that by billions of dollars in leverage, it becomes one of the most profitable, most-crowded trades in modern finance history.
For decades, this worked because Japan kept interest rates at zero while the rest of the world paid real yields. The strategy is called a “carry trade” because you’re being paid — carried — by the interest rate difference between the two currencies.
If you’re new to how macro moves affect crypto, is crypto a good investment and bitcoin dominance cover related themes. For the “why does macro even matter for Bitcoin” question, crypto market cycle has the framework.
How does the yen carry trade work?
Walk through a simplified worked example. Numbers are illustrative but the mechanic is real.
Step 1. A US hedge fund borrows ¥1,000,000,000 (one billion yen) from a Japanese bank at 0.1% interest per year. Total interest cost for one year: ¥1,000,000. Basically nothing.
Step 2. The fund converts those yen to dollars at, say, ¥150 per USD. That gives them ~$6.7 million.
Step 3. The fund invests the $6.7 million in a US Treasury bond paying 4.5% annually. That’s $301,500 in interest over one year.
Step 4. At the end of the year, the fund earned $301,500 on the US bond and owes ¥1,001,000,000 back to the Japanese lender.
Step 5. The fund converts $6.7 million back to yen at ¥150. It gets ¥1,005,000,000. It pays back the loan (¥1,001,000,000). Left over: ¥4,000,000 (~$27,000).
Net result: $301,500 US bond interest plus $27,000 FX gain from the tiny yen depreciation minus the ¥1M yen interest ≈ $321,000 of pure spread on a $6.7M position. Roughly 4.8% risk-free-looking annual return — as long as the exchange rate holds and the interest rate gap stays.
Now imagine that hedge fund uses 5× or 10× leverage. Suddenly the “5% carry” becomes 25%–50% annually. This is why global institutions loaded into this trade for two decades.
The catch, as anyone who’s done BitGet leverage at 25× knows, is that leverage cuts both ways. If the yen strengthens or Japanese rates rise, the position unravels fast.
Why does Japan have such low interest rates?
To understand the carry trade you have to understand why Japan’s rates were near zero for so long. It’s a cultural and economic story going back 35 years.
In 1990, Japan had one of the biggest asset bubble crashes in history. The Nikkei stock index peaked at around 39,000 in late 1989 — and then collapsed, spending the next three decades below that level. Real estate prices in Tokyo halved. A generation of Japanese savers lost everything and never fully recovered.
The trauma changed national behaviour. Rather than spending or investing, Japanese households started saving obsessively. The country entered a decades-long period of deflation — prices actually falling year on year, which sounds nice for consumers but is a disaster for growth. Businesses can’t raise prices. Wages stagnate. Everyone hoards cash because it’s getting more valuable, which starves the economy of activity.
The Bank of Japan tried the standard central bank playbook: lower interest rates to encourage borrowing and spending. It didn’t work. So they lowered rates further. And further. Eventually they lowered them to zero. Then they went negative — banks paid the BOJ to hold their reserves, hoping to force money out into the real economy.
For roughly 25 years, borrowing yen was almost free. Meanwhile, other countries kept normal interest rates. That gap is what created the carry trade.
To understand how monetary policy affects Bitcoin more broadly, see crypto market cycle and what is Bitcoin for the macro framing.
What is the Bank of Japan?
The Bank of Japan (BOJ) is Japan’s central bank — the equivalent of the US Federal Reserve, the European Central Bank, or the Bank of England. It sets monetary policy for the yen, controls the country’s base interest rate, and manages the money supply.
Key figures worth knowing:
- Governor: Kazuo Ueda (appointed 2023). Widely viewed as more hawkish than his predecessors — meaning more willing to raise rates.
- Board member: Hajime Takata, who has publicly floated the idea of a larger-than-usual hike at the September 2026 meeting.
- Current policy rate: 1.00% as of writing.
- Expected rate: 1.25% after the 17–18 September 2026 meeting. Overnight index swap markets price this at 97% odds.
The BOJ decisions matter globally because of the trillions of dollars in carry trade positions tied to Japanese rates. When the BOJ moves, global risk assets — including Bitcoin — move with them.
The Fox Business segment above gets the mechanic right but doesn’t quite convey how sensitive global markets are to a single BOJ meeting. Watch closely on 18 September.
What is a yen carry trade unwind?
An “unwind” is when investors reverse the carry trade in bulk. The mechanic is straightforward but the consequences are ugly.
To close a carry trade position, an investor has to:
- Sell the asset they bought (US bond, tech stock, Bitcoin).
- Convert those dollars back into yen.
- Repay the yen loan.
When one hedge fund does this, nothing happens. When thousands do it simultaneously — usually triggered by a Japanese rate hike or unexpected yen strength — the market sees:
- Simultaneous selling of US assets (stocks and bonds down)
- Simultaneous dollar-selling and yen-buying (yen strengthens fast)
- Waves of forced selling as leveraged positions get margin-called
That’s why unwinds cause sharp cross-asset drawdowns. It’s not one market — it’s every risk asset falling together while the yen rockets higher. Bitcoin gets caught in this because, in the eyes of a global hedge fund, BTC is a risk asset in the same bucket as tech stocks.
If you don’t have a plan for how to survive one of these events, crypto trading psychology and how to set stop losses in crypto trading are the two posts that matter most.
Did the yen carry trade cause the August 2024 crypto crash?
Yes — largely. The August 2024 event is the case study every macro-aware trader now studies.
On 31 July 2024, the BOJ surprised markets with a rate hike from 0.10% to 0.25%. Simultaneously, the US Federal Reserve signalled it was about to start cutting rates. The interest rate differential — the whole basis of the carry trade — compressed in two directions at once.
Over the next four trading days:
- The yen strengthened roughly 8% against the dollar.
- The Nikkei collapsed 12% in a single session on 5 August 2024 — its worst day since 1987.
- Bitcoin dropped ~20% in the same window, according to Bank for International Settlements analysis cited by BeInCrypto.
- Tech stocks got smoked. Nvidia lost ~13% in three days.
The pattern was textbook carry trade unwind: leveraged positions liquidated across every asset class as traders scrambled to close yen shorts. Nothing was safe except cash and government bonds. Bitcoin — often marketed as an inflation hedge — behaved like a leveraged tech stock, because in the macro plumbing of institutional finance, that’s exactly what it currently is.
Anyone who was heavily long crypto with no stop losses learned an expensive lesson that week. Anyone who understood the carry trade got out early.
How does the yen carry trade affect Bitcoin?
Bitcoin is now firmly correlated with the yen carry trade during unwinds. Not because of anything in the Bitcoin code, but because of who holds Bitcoin and where their leverage comes from.
The correlation has been documented across every BOJ hike in the current cycle:
- August 2024: BOJ hike from 0.10% to 0.25% → Bitcoin -20% within days
- December 2024: BOJ hike commentary → Bitcoin -8% intra-week
- March 2025: BOJ hike from 0.25% to 0.50% → Bitcoin -12%
- July 2025: BOJ hike from 0.50% to 0.75% → Bitcoin -18%
- February 2026: BOJ hike from 0.75% to 1.00% → Bitcoin -25%
Per BeInCrypto’s analysis, Bitcoin has fallen 20–31% following each of the past three BOJ rate hikes in 2026.
The mechanism is this: hedge funds and institutional investors using yen-funded leverage held meaningful Bitcoin positions. When Japan hikes, those positions get liquidated first — Bitcoin is the highest-volatility asset in most portfolios, so it hits margin thresholds fastest. Once BTC breaks a key level, algorithmic trend-followers pile in short. The result is a downdraft that lasts days to weeks before positioning resets.
Retail traders looking at “why is Bitcoin falling” often blame ETF outflows or on-chain metrics. The real driver, more often than not, is macro liquidity. Understand the yen carry trade and you’ll spot the moves before the crypto news cycle does.
For the broader Bitcoin macro framework, bitcoin halving explained, bitcoin dominance, and crypto market cycle are the trilogy worth reading.
Is the yen carry trade over?
No — but it’s shrinking fast.
The trade is only fully “over” when Japan’s rates rise high enough that the interest rate differential with the US disappears. Right now, the maths still works: at BOJ 1.00% vs Fed 3.25–3.50%, the gap is 225–250 basis points. Even after a hike to 1.25%, the gap only narrows slightly, and there’s still an economic argument for the carry.
But three forces are compressing it simultaneously:
One. BOJ is raising rates. Every hike shrinks the carry margin.
Two. The US Fed is also cutting rates in 2026 as inflation fell — reducing the yield side of the trade.
Three. The yen is strengthening. When the yen appreciates, the FX component of the carry becomes a loss instead of a small gain, which turns positive-carry trades into break-even or negative-carry.
The result is what markets call a “compression” — the trade doesn’t disappear, but the marginal position becomes unprofitable, and the marginal trader unwinds. Over months, this drains liquidity from all the risk assets the carry trade funded.
Per BeInCrypto reporting, hedge funds are now positioning for further yen strength, which itself accelerates the unwind — a self-reinforcing pattern.
What happens if the BOJ raises rates further?
Base case for what a 25bp hike to 1.25% on 18 September 2026 could look like — if positioning is anything like historic patterns:
Immediate reaction (Days 1–3): Yen strengthens 2–5% against USD. Nikkei falls 3–8%. US tech stocks under pressure. Bitcoin sells off 5–15% as leveraged positions unwind.
Week 1–2: Trend continues if there’s follow-through selling. Retail crypto positions with tight stops get hit. Bots and grid strategies may pause or trigger sell orders. Watch BitGet funding rates on BTC/USDT perps — they invert sharply during unwinds.
Week 2–4: Market absorbs the news. If BOJ signals a “one and done” pause, risk assets can bounce hard. If they signal more hikes to come, drawdown extends and Bitcoin can test lower ranges. Historically Bitcoin has recovered 60–80% of unwind-driven losses within 4–8 weeks.
Longer-term: If BOJ continues hiking through 2027, the carry trade compresses toward zero and structural liquidity for global risk assets decreases. Crypto stays functional but volatility increases and beta to macro tightens.
None of this is a prediction — it’s a framework for reading news as it lands. The exact response depends on positioning going into the meeting, and positioning always shifts.

What should crypto traders do about the yen carry trade?
Not much, if you’re a long-term holder. A lot, if you’re actively trading. Here’s the practical playbook.
If you’re a long-term Bitcoin holder:
– Don’t panic-sell into an unwind. Historically, macro shocks compress Bitcoin 20–30% and then recover.
– Do keep your long-term holdings on cold storage via a Ledger Nano X — an unwind doesn’t stop exchanges from getting rate-limited or freezing withdrawals during panic. The hardware wallet doesn’t care.
– Consider adding modest DCA buys on the drawdown — DCA bots via BitGet’s DCA bot can automate this so you don’t have to time it emotionally.
If you’re an active trader:
– Reduce leverage before the BOJ meeting. If a 25bp hike is fully priced, a “hawkish surprise” (larger hike or hawkish forward guidance) will destroy over-leveraged longs. See BitGet leverage explained for the maths on how quickly leverage kills positions.
– Widen your stop losses OR cut position size. Volatility around a BOJ hike is 2–3× normal. Same stop distance means 2–3× the risk. See how to set stop losses in crypto trading and crypto trading position sizing.
– Watch USDJPY as your early-warning signal. If USDJPY drops below key levels (140, 135, 130), assume risk-off and reduce crypto exposure. USDJPY leads Bitcoin by 1–3 days at these inflection points.
– Don’t be short-side complacent either. BOJ meetings can also produce dovish surprises — where markets expect a hike and don’t get one, the yen weakens sharply, and every risk asset rips higher. Shorts get squeezed hard.
If you’re running bots:
– Grid bots (BitGet spot grid) get whipped in high-volatility unwinds. Consider pausing 24 hours before a BOJ meeting.
– DCA bots keep running — they benefit from the drawdown. See my BTC/USDT spot bot for the settings I use through macro events.

How does the yen carry trade compare to other macro trades?
For context, the yen carry is one of several macro trades that periodically shake crypto. Understanding all three helps you diagnose what’s actually driving a move.
Yen carry trade. Discussed here. Trigger: BOJ rate changes. Signal to watch: USDJPY exchange rate.
Dollar liquidity trade. When the Fed tightens or eases, global dollar liquidity contracts or expands. Bitcoin correlates strongly with global M2 money supply — up when liquidity expands, down when it contracts. Signal: DXY (dollar index) direction, Fed balance sheet trajectory.
China credit impulse. When China injects liquidity via bank reserve requirements or fiscal stimulus, it eventually flows into risk assets globally. Signal: Chinese M2 growth, PBOC reserve requirement changes.
All three are macro-driven forces. All three affect Bitcoin. During the August 2024 unwind, all three tightened at once — hence the ferocity of that specific move. When any two are loosening, Bitcoin tends to trend up. When any two are tightening, prepare for downside.

Frequently asked questions
What is the Japanese yen carry trade in simple terms?
The yen carry trade is when investors borrow money in Japan at very low interest, convert those yen into another currency (usually US dollars), and invest in higher-yielding assets like US Treasury bonds, stocks, or Bitcoin. The profit is the difference between the low Japanese interest rate and the higher rate they earn abroad.
Why does Japan have such low interest rates?
Japan has kept interest rates near zero for around 25 years to try to escape deflation. The 1990 stock and property crash traumatised Japanese savers, who then hoarded cash rather than spending. The Bank of Japan lowered rates to zero (and briefly negative) to try to force money back into the economy.
How does the yen carry trade affect Bitcoin?
Bitcoin has been highly correlated with yen carry trade unwinds. Every major BOJ rate hike in 2026 has coincided with a 20–31% Bitcoin drawdown. When leveraged carry positions unwind, Bitcoin gets sold along with other risk assets like tech stocks.
What happened in the August 2024 crypto crash?
On 31 July 2024, the BOJ raised rates from 0.10% to 0.25%. Within days, the yen strengthened ~8% against the dollar. The Nikkei fell 12% in a single session — its worst day since 1987. Bitcoin dropped ~20% as leveraged carry trade positions unwound simultaneously across global markets.
Is the yen carry trade over?
Not yet. Even after an expected hike to 1.25% on 18 September 2026, the interest rate gap between Japan (1.25%) and the US Fed (3.25–3.50%) is still about 225–250 basis points. The trade is compressing but not dead. It becomes fully unprofitable only if the gap closes further, which would require several more BOJ hikes or aggressive Fed cuts.
What’s happening at the September 2026 BOJ meeting?
Markets price a 97% probability of a 25 basis point rate hike from 1.00% to 1.25% at the 17–18 September 2026 meeting. Governor Kazuo Ueda and board member Hajime Takata have both signalled hawkishness, raising the possibility of a larger-than-usual increase.
Should I sell my Bitcoin before a BOJ meeting?
If you’re a long-term holder, historically no — macro drawdowns of 20–30% have recovered within 4–8 weeks. If you’re actively trading with leverage, reducing exposure before a major central bank meeting is defensible risk management. Always trade based on your own risk tolerance, not on macro predictions.
How do I watch for a yen carry trade unwind?
Monitor USDJPY (the yen-dollar exchange rate). A sharp move below 140, 135, or 130 signals accelerating yen strength, which precedes risk-asset selling. Also watch BOJ meeting dates (published in advance) and news from BOJ Governor Kazuo Ueda’s speeches.
Does the carry trade affect other cryptos besides Bitcoin?
Yes — every major crypto tends to fall with Bitcoin during macro unwinds, often more sharply. Altcoins and memecoins are higher-beta than Bitcoin. During a yen shock, expect BTC to fall 20% and mid-cap alts to fall 30–50%. See best Solana meme coins for context on the highest-beta segments.
Final word
The yen carry trade is one of those macro forces that sounds abstract until you realise it’s the single biggest driver of unexplained Bitcoin drawdowns in the modern cycle. Every time you see BTC drop 15% “for no reason”, check what USDJPY did. Nine times out of ten, the answer is there.
You don’t need to be a macro expert to survive these events. You need three things: sensible position sizing, stops on active positions, and a long-term view that treats 20% drawdowns as bumps in the road rather than emergencies.
Right — over to you.
