Analysis of the impact of the Bank of Japan's interest rate hike on Bitcoin

Key conclusions

Short-term bias towards a lower low (65% probability) : BTC may test the $87,000-$88,000 support zone this week, after which a temporary bottom is expected to form and a rebound is anticipated. Although the interest rate hike is already highly priced in (98% probability), the mechanical unwinding of yen carry trades and the pressure of derivatives liquidation may still trigger a continued downward momentum.

The logic that the medium-term negative factors have been fully priced in holds true : clear signals have accumulated on the blockchain, the weekly chart is oversold, and historical patterns show a strong rebound after the sharp drop, laying the foundation for subsequent gains.

Bank of Japan interest rate hike expectations

Meeting timing and policy expectations

Market pricing situation

• Polymarket : 98% probability of a 25 basis point rate hike
• A Reuters poll of 70 economists indicates that 90% expect a December rate hike to 0.75%.
• Bloomberg survey : 100% of 50 economists expect interest rate hikes.

Interest rate hikes have been largely priced in , but historical data shows that even when fully anticipated, their implementation can still trigger market volatility.

Historical precedent: BOJ interest rate hikes and BTC price movements

Historical pattern : BOJ rate hikes are transmitted to global risk assets through the unwinding of yen carry trades. BTC, as a highly volatile asset, is the first to be affected, but sharp drops often create buying opportunities.

Technical Analysis: Oversold Conditions and Downside Risks Coexist

Multi-timeframe structure

Current price : $89,535 (December 15, 04:26 UTC)

Key technology position

• Near-term support : $88,000-$87,400 (lower Bollinger Band on the daily/4-hour chart + dense bullish consolidation zone)
• Resistance level : $90,000-$91,000 (Daily EMA20 + the biggest pain point for options)
• The weekly RSI has entered oversold territory at 38.8 , suggesting that selling pressure is nearing exhaustion, but the structural downtrend has not yet reversed.

Derivatives Market: Significant Downside Liquidation Pressure

Positions and funding rates

Distribution of liquidation risks

• Total liquidation amount in 24 hours : $108.5M (longs $93.6M vs. shorts $14.9M )
• Downside liquidation pressure : Cumulative long positions of $612 million have been distributed to $86,815.
  • $88,815 : $42M
  • $87,280 : $56M
• Upside liquidation pressure : Initially only $5.3M ($89,605), with significant increases only at higher price levels.

Risk assessment : If the liquidation cluster below is triggered, it may cause a chain reaction , accelerating the decline to the $87k area.

On-chain data: Whale accumulation vs. short-term selling pressure

Exchange liquidity

Whale and Long-Term Holders

• Long-term holders (>155 days) : Holding 14.35 million BTC ( 68.3% of circulating supply), stabilizing in December.
• Whales (1,000-10,000 BTC) : Net accumulation of 47,584 BTC in early December, reversing previous sell-offs.
• Number of whale addresses : Up 12% from October, absorbing 4 times the average weekly mining output during price pullbacks.

Valuation Metrics

• MVRV Z-Score : 1.17 (Slightly overvalued but not yet at the top of the cycle)
• Puell Multiple : 0.87 (signaling near historical lows, easing pressure on miners' income)

Interpretation : On-chain data shows that institutional investors and whales are the main players in the accumulation phase , while short-term holders capitulating and long-term holders taking profits are absorbed, forming structural support.

Social Sentiment: Short-term Panic vs. Medium-term Optimism

Mainstream Narrative

1. Yen carry trade unwinding : BOJ rate hikes increase borrowing costs, triggering a global liquidity crunch and a mechanical sell-off of risk assets.
2. History may repeat itself : referencing the 25% plunge followed by a rebound of over 100% in July 2024, a similar opportunity may be emerging now.
3. Testing $70,000 : An extremely bearish view suggests that a liquidity crunch could push BTC down to $70,000.

KOLs have differing opinions.

• The bearish camp emphasizes the mechanical impact of rising borrowing costs and advises caution from December 15-21, expecting an initial drop to $85,000-$87,000 before stabilizing.
• Bullish view : The monthly chart shows higher highs and lower lows supporting a bull market cycle, while the weekly chart's oversold condition and on-chain accumulation form a basis for a reversal.

Emotional polarity

• Short term (this week) : Bearish (dominated by panic, high volatility expected)
• Medium term (December - Q1 2026) : Mixed bullish (negative factors fully priced in + support from fiat currency depreciation narrative)

Comprehensive judgment: Probability-weighted scenario analysis

Scenario 1: The price will hit a new low ( 65% probability)

Triggering conditions :

• BOJ raises interest rates as expected; yen carry trades close out at an accelerated pace.
• The liquidation cluster below ($88k-$87k) was triggered, causing a chain reaction.
• Stock markets fell in unison, and global risk assets moved in tandem.

Target range : $87,000-$88,000 (lower Bollinger Band on the daily chart + dense consolidation zone)

Duration : Rapid bottoming out within 1-3 days, followed by stabilization.

Supporting evidence :

• The weekly RSI is at 38.8, indicating oversold conditions and selling momentum is nearing exhaustion.
• Whales have historically accumulated a large amount of tokens in this range (47,000 BTC by early December).
• Puell Multiple 0.87 suggests the miners' surrender is nearing its end.

Scenario 2: Direct rebound (probability 35% )

Triggering conditions :

• The interest rate hike has been fully priced in (98% probability), and "what's bad news is good news" applies here.
• The current price has already absorbed the selling pressure, and effective support has formed around $89k.
• The Fed's easing expectations offset the impact of BOJ tightening.

Target area : Break through the $91,000-$92,000 resistance level, then retest $94,000.

Risk factors :

• This needs to be accompanied by a positive shift in funding rates and a recovery in long derivatives.
• On-chain outflows need to continue, and exchange balances will further decline.

Operational suggestions and risk warnings

Short-term strategy (December 15-21)

Conservative type :

• The best approach is to remain on the sidelines and wait for a signal of increased volume and stabilization in the $87k-$88k range.
• Pay attention to whether the weekly RSI falls below 35 (extremely oversold) and whether the daily MACD divergence strengthens.

Radical type :

• Establish positions in batches at $88,500, $87,500, and $86,500, with a stop-loss order placed at $85,500.
• Pay attention to the first 4-hour candlestick chart after the BOJ statement on December 19th. If a long lower shadow engulfing pattern appears, consider adding to your position.

Mid-term outlook (Q1 2026)

• Basic Scenario : After forming a bottom at $87k-$88k, with the BOJ interest rate hike now a reality, continued on-chain accumulation, and the strengthening narrative of fiat currency devaluation, BTC is expected to resume its upward trend in Q1 2026.
• Historically , a similar event in July 2024 led to a more than 100% rebound in BTC, and the current cycle may see a similar pattern.

Risk Warning

1. Extreme downside risk : If the $87k support level is breached, the price could accelerate its decline to $83k-$85k (lower Bollinger Band on the weekly chart).
2. Macroeconomic Black Swan Events : Deteriorating US employment data and escalating geopolitical conflicts could amplify the decline.
3. Technical breakdown : A weekly close below $85k would invalidate the bull market structure.

in conclusion

The probability of a Bank of Japan rate hike this week is extremely high (98%). Although this has been fully priced in by the market, historical experience and current technical indicators suggest a short-term bias towards testing the $87k-$88k support zone (65% probability). However, signals such as weekly oversold conditions (RSI 38.8), on-chain whale accumulation (net increase of 47,000 BTC in December), and continuous outflows from exchanges (net outflow of 60,000 BTC in 30 days) indicate that the medium-term "bad news has been priced in and a rebound is expected" logic holds true . Referring to the precedent of a rebound of over 100% after the crash in July 2024, this bottoming out may create a significant buying opportunity. It is recommended to pay attention to the volume stabilization signal in the $87k area and the market reaction after the policy statement on December 19th.
