Bitcoin Eyes BOJ: Yen Strength and the Carry Trade’s Next Move
Japan’s central bank is widely expected to lift its short-term policy rate to 0.75% in December, marking its highest level since 1995. The move signals growing confidence in Japan’s economic recovery and strengthens expectations of further policy normalization after years of ultra-loose monetary settings. A rate hike of this scale also reflects the Bank of Japan’s shifting stance as inflation stabilizes above its long-term target and wage growth shows resilience.
A higher policy rate could have broader global implications, particularly for risk assets like bitcoin. A stronger yen often encourages investors to unwind carry trades, where cheap yen borrowing is used to fund positions in higher-yielding or riskier markets. If this unwind accelerates, it may create de-risking pressure, tighten cross-asset liquidity, and weigh on bitcoin’s near-term momentum.
What’s changing at the BOJ
Reporting from Reuters and Bloomberg suggests policymakers are leaning toward a 25 bps hike at the Dec. 18–19 meeting, with the government seen tolerating the move. Governor Kazuo Ueda has hinted at the possibility while signaling caution on forward guidance. The yen firmed after the reports, and JGB yields climbed to multi-year highs. Reuters+2Reuters+2
Why the carry trade matters for crypto
For decades, hedge funds have borrowed at low yen rates to finance positions in higher-beta assets. As yen funding costs rise, the carry’s appeal fades, prompting position trimming in liquidity-sensitive markets including BTC. Recent gains in the yen underscore this risk channel from Tokyo into global risk assets.
Bitcoin’s setup into the decision
Bitcoin recovered from sub-$90K prints this week but has struggled to sustain moves above ~$93K, with realized and implied volatility elevated versus equities. Macro rate expectations remain a key driver into year-end.

Scenarios to watch
Fast yen rally / risk-off
A sharp BOJ surprise or hawkish signal could accelerate repatriation, tighten liquidity, and pressure BTC.
Measured hike / “constructive ambiguity”
A well-telegraphed 25 bps move with cautious guidance may limit cross-asset stress.
No hike / delay
Would ease immediate unwind risk but keep sensitivity high if the yen strengthens on other catalysts.
Cross-currents to balance
While history links stronger yen episodes with de-risking, some strategists argue the global footprint of the carry trade is smaller than in prior cycles, potentially muting spillovers. Still, with BTC liquidity fragmented across venues, even moderate deleveraging can amplify moves.

Conclusion
Markets have mostly priced in a potential December BOJ rate hike, leaving the yen’s trajectory and the pace of carry-trade unwinding as key drivers for bitcoin’s liquidity into year-end. If investors scale back positions gradually, the impact on crypto markets may remain contained, especially if global equities stay steady.
However, a stronger-than-expected yen rally could trigger a faster reduction in carry trades, tightening liquidity and pressuring risk assets. In that scenario, bitcoin may face renewed volatility, with key support levels potentially coming into focus as traders react to shifting cross-asset flows.
