Bitcoin price prediction: BTC downside risk deepens amid BOJ rate sentiment
Bitcoin price began the week on a fragile note following a decisive bearish breakout from a four-week ascending triangle structure. This pattern had been forming since November, characterized by rising higher lows from $80,500 and a horizontal ceiling around $94,000. Last week, as the triangle compressed further, Bitcoin narrowed into a tight consolidation range between $89,200 and $96,400 before finally breaking lower on Sunday. The decline to $87,600 marked a 12-day low and confirmed the downside resolution of the pattern.
Highlights
- Bitcoin retest capped at $90K following triangle breakdown confirmed by high volume.
- Bank of Japan rate hike could trigger deleveraging and a 25% BTC valuation drop.
- Fear and Greed Index falls to 24 as macro risk overshadows short-term recovery hopes.
The breakout was not only technical but also supported by a spike in traded volumes, indicating strong bearish sentiment. Monday’s session opened higher and managed to push Bitcoin from $88,100 to $89,900, delivering intraday gains of 2%. However, those gains have stalled at the broken triangle trendline, which now acts as resistance. This resistance zone coincides precisely with the 20 EMA on the 4-hour chart, just shy of the $90,000 psychological barrier, making the current move appear more like a retest than a reversal.

A closer look at the 4-hour chart shows the $90,000 region has now been enveloped by the 20, 50, and 100 EMAs, creating a tight cluster of technical rejection. Unless price decisively clears this zone, the broader structure points toward continuation to the downside. Short-term bullish setups appear weak in this context, especially as market participants brace for a critical fundamental risk event that could dictate Bitcoin’s next move.
BOJ tightening may trigger BTC forced liquidation of leveraged positions
All eyes are now on the Bank of Japan’s policy meeting scheduled for December 18–19. Prediction markets and macro analysts expect a 25 basis-point rate hike. Such a move would be highly significant given Japan’s historic role in global carry trades, where investors borrow in yen to fund riskier bets in foreign assets like Bitcoin. Rising Japanese yields are already putting pressure on this model, and further tightening could accelerate deleveraging.
The global crypto sentiment is already reacting. The fear and greed index has slipped from 28 to 24 in the past week, reflecting renewed risk aversion. As yen-funded leveraged trades unwind, crypto markets may be exposed to forced selling. Month-to-date, Bitcoin is down 0.84%, and if Japan hikes to 75 basis points, the move could trigger a steeper decline in crypto valuations. Historically, similar hikes have seen Bitcoin fall by as much as 20–25%.
From a technical and fundamental standpoint, Bitcoin’s structure now leans bearish. The failed triangle breakout, failed retest around $90,000, and looming macro threat from Japan’s rate hike path all align for further downside pressure. If BOJ policy tightens more than markets expect, price action could spiral to as low as $70,000 before December closes. Until Bitcoin can reclaim and hold above $90,000, downside risk remains the dominant narrative.
We discussed how Bitcoin failed a breakout at $94,000, showing a speculative bounce lacking spot demand conviction. Post-Fed rally faded as prices struggled to sustain momentum above $92,600 while leverage kept building.
