Bitcoin Inflection Point After the BOJ Rate Hike: A Weekend When a Break Above 88–89K Could Decide the Santa Rally

The core message can be distilled into one point. The Bank of Japan’s rate hike introduced short-term selling pressure, but Bitcoin’s structural trend still has room to reverse, and this weekend’s volatility could shape the remainder of the year’s trajectory. We maintain our view that a Santa rally remains possible; while data show an uptick in selling pressure, the probability of a decisive break of recent lows appears limited for now.

Macro variables: BOJ rate hike and the shadow of yen carry unwinds

Japan executed its largest rate hike since 1995, a headwind for risk assets across the cryptocurrency market. We note that parts of this macro shock were likely pre-priced as markets had already been primed for potential yen carry-trade unwinds. Indeed, exchange inflows of Bitcoin and the average deposit size increased into the event, but there was only a limited acceleration immediately after the announcement. This suggests some short-term profit-taking without signs of expanding systemic risk or capitulation-level fear.

Technical inflection: 88–89K, a triple-layered resistance confluence with the POC

The most important price zone is 88–89K dollars. This band aligns with the uptrend line connecting the November 21 and December 1 lows, the upper boundary of the short-term descending channel drawn through December 10, December 12, and December 17, and the top of a larger descending channel that has been in place since October 6. The volume profile’s POC also sits here, creating dense resistance. A forceful breakout above this level would be interpreted as a trend-reversal signal; conversely, a clear rejection followed by a pullback could extend the short-term correction.

On-chain and flow checkpoints: Why we see “limited downside”

Starting with confirmed data, exchange reserves and net inflows have dominated since December 10, strengthening short-term sell pressure. The average deposit size also rose, but there was no outsized surge right after the BOJ announcement, and futures open interest did not show a conspicuous build-up in leverage. The Coinbase premium remains in negative territory, consistent with past patterns that often framed such levels as buyable during broader uptrends.

In our analysis, when the short-term holder profitability ratio falls below 0.96, it typically signals “short-term holder capitulation.” Similar setups in July and September 2024 and in March and May 2025 coincided with bottom formation. Another key point is that spot volumes have led futures volumes; in prior double-bottom zones, roughly 100,000 BTC of spot transactions confirmed real buying absorption at the lows. Meanwhile, top-side froth indicators in futures appear more subdued than in the previous cycle, mitigating overheating risk.

From a long-term holder perspective, supply-adjusted CDD remains quiet, and there has been no pronounced outflow from the 155+ day cohort (one-year basis), indicating limited supply-side pressure. Market-price-based cumulative volume has flipped from neutral to accumulation phase, and taker buy dominance appears to have progressed from distribution into a sideways phase and then into accumulation. This combination resembles patterns commonly observed at the early stages of a cycle in cryptocurrency market analysis.

Short-term scenarios and risk boundary

In the short term, we caution that higher exchange balances imply an available overhang of sell supply, potentially amplifying volatility. That said, we judge the odds of a prolonged decline without printing new lows to be relatively low, and we expect the post–U.S. session flow to clarify directional bias. The invalidation line is straightforward. A long-bodied bearish close below the prior low would lead us to abandon the Santa rally scenario and turn more conservative into Q1–Q2 next year. Conversely, if price sweeps the lows intraday but recovers to close with a tail, we would maintain the view of limited downside/defended lows.

Investment takeaways

For investors, this weekend sits at the intersection of a macro shock and a technical inflection. Despite the BOJ’s rate hike, if long-term holder supply pressure remains muted and spot-led flows persist, a breakout through 88–89K could reignite the Santa rally in the cryptocurrency market. On the other hand, a strong close below the prior low should be treated as a warning to recalibrate medium-term positioning. Monitoring shifts in on-chain directionality, any recovery in the Coinbase premium, and potential overheating signals in futures open interest can help inform decisions during this period of elevated volatility.
