You may have noticed an ongoing trend: the Japanese yen is rising in value, but Bitcoin has barely gained, and even occasionally posted losses. If you think this is only a Japan-specific issue, you are underestimating the ripple effect on the crypto market when the world's largest "free funding pool" starts to close its taps.

The impact of the yen carry trade reversal on Bitcoin does not happen via a single event, but is amplified step by step through this chain: draining liquidity → triggering sell-offs in tech stocks → squeezing crypto leverage positions.
Three Amplification Layers of How Carry Trade Reversal Transmits to Bitcoin
Layer 1: The global liquidity "tap" is tightened
The core mechanism of the carry trade is: global investors borrow Japanese yen at extremely low cost, exchange it for U.S. dollars, and invest the funds in high-yield assets including U.S. tech stocks and Bitcoin. For decades, this "tap" has continuously supplied liquidity to global risk assets.
When the yen suddenly appreciates and financing costs rise, carry trade investors face a "double whammy": the yen they borrowed becomes more expensive, while the risk assets they bought with that money may be falling in price. The only rational choice is to unwind positions: sell assets, exchange the proceeds back to yen to pay off their debts.
This is not a voluntary "to sell or not to sell" decision, but forced liquidation of leveraged positions. Per market estimates, the total size of the broad yen carry trade ranges from $9.3 trillion to $19.2 trillion, equivalent to the combined GDP of Japan, Germany and the UK. When this huge sum of funds starts to retreat, global liquidity will see a structural contraction.
Layer 2: Tech stocks take the first hit, and liquidity pressure spreads to crypto
The carry trade saw a structural shift after 2023: more and more hedge funds no longer borrow yen to buy U.S. Treasuries, but borrow yen to purchase U.S. tech stocks, especially AI-related sectors. Data from Goldman Sachs shows that investment in the AI sector has accounted for more than 1% of U.S. GDP, and a large share of that is backed by yen-denominated financing.
This means once a sharp yen appreciation triggers position unwinding, the first assets to be sold off are the most liquid, highest-valued tech stock positions. When tech stocks fall, overall market risk appetite drops systematically, and crypto assets, as high-beta risk assets, usually follow to face selling pressure.
Layer 3: The high-leverage structure of the crypto market amplifies the shock
The crypto market has deep derivatives markets and widespread high leverage, making it extremely sensitive to sudden liquidity contractions. When large-scale carry trade unwinding happens, a chain reaction will form across funding rates, open interest, and clusters of high-leverage positions. Per analysis from KuCoin, a sharp rebound of the yen could drag Bitcoin down below $60,000. In August 2024, the Bank of Japan's unexpected interest rate hike triggered carry trade liquidation, and Bitcoin plummeted from around $62,000 to $49,000 in a week, a roughly 20% drop, which is the most direct precedent.

Two Transmission Paths: The FIMA Mechanism is a Watershed
Jeffrey Ding, lead analyst at HashKey, points out that the capital flow from carry trade unwinding evolves in two stages:
Path A (Short-term): Capital flows back to Japan globally, putting pressure on U.S. tech stocks and U.S. Treasuries.
This is the most direct deleveraging effect. If Japan is forced to directly sell U.S. Treasuries to intervene in the exchange rate, it may trigger turmoil in the U.S. Treasury market, and all risk assets will face broad selling pressure.
Path B (Medium and long term): Bitcoin may become a beneficiary if the FIMA mechanism is adopted
Arthur Hayes, co-founder of BitMEX, proposed a more actionable scenario: Japan's Ministry of Finance uses its holdings of U.S. Treasuries as collateral via the FIMA repo facility to borrow U.S. dollars from the Federal Reserve, then uses those dollars to buy yen to push up the exchange rate. The essence of this mechanism is the Fed indirectly printing money, which will inject a large amount of dollar liquidity into the market.
If this path is realized, Bitcoin and physical gold will be the biggest beneficiaries — because the expansion of the Fed's balance sheet has a positive correlation with Bitcoin price. But it is worth noting that this path requires the Fed to relax counterparty limits for the FIMA facility, so it is still a "potential path" rather than a certain outcome.
Risk Alert: At the end of July 2026, the U.S., Japan and South Korea carried out a rare joint intervention in the foreign exchange market, the yen surged 3% in a single day, Bitcoin dropped 4.5% in 12 hours, and more than $240 million worth of positions were liquidated. UBS believes "this round of carry trade unwinding is only halfway done". The real selling pressure may still be ahead.
Verification Tip: Add the USD/JPY exchange rate to your daily watchlist. If it keeps falling below 160, it means the carry trade is entering a full unwinding phase. After the 2026 July intervention, the yen briefly rebounded to 157, then returned to near 160 — every fluctuation at this level may correspond to a sharp shakeout in the crypto market.
Next Step: Check the on-chain lending rates and funding rates of the altcoins in your portfolio. If these indicators rise in tandem with yen appreciation, it means your positions are at the critical point of leveraged liquidation. The impact of carry trade reversal is not a matter of "if it will come", but "when it will come" — you need to adjust your positions to a level that can withstand this shock before it happens.
