Bitcoin [BTC] is starting to feel the heat of next week’s Bank of Japan (BoJ) decision.
With a 25 basis point rate hike widely expected, markets appear to be adjusting ahead of time. Recent data says risk is already being trimmed, raising the odds that the sell-off happens ahead of the headline.
This leaves room for a “sell the rumor, buy the fact” reaction once the decision is out.
Sayonara, BTC gains!
Bitcoin is slipping ahead of the BoJ’s expected 25 bps rate hike on the 19th of December… and we know this setup all too well. Previous rate hikes have repeatedly aligned with sharp BTC drawdowns as yen liquidity tightened and risk appetite faded.
In March 2024, Bitcoin fell about 23% after a rate hike. In July 2024, it dropped another 26%. January 2025 saw an even bigger pullback of nearly 31%. With another hike widely anticipated, traders appeared to de-risk early, pushing BTC lower before the announcement.

The pattern of course, doesn’t guarantee a repeat. But it certainly explains why nerves are rising fast.
The selling may have started early
Investors aren’t waiting for the policy decision to react.

During earlier BoJ hikes, Bitcoin saw Exchange Inflows rise after the announcement, signaling panic-driven spot selling.
This time, Exchange Netflows already showed rising inflows ahead of 19 December. That pointed to early spot selling and proactive risk reduction.

Funding behaviors also have a similar reaction.
During prior hikes, Funding Rates collapsed after the decision. Now, they have already drifted lower and turned unstable, suggesting that leverage was unwinding in advance.
That move aligned with expectations, becoming fully priced
So what happens after the meeting?
That early adjustment changes how this plays out. Unlike past hikes, the BoJ’s shift has been talked about for months. Yen carry trades already unwound, and tighter liquidity was no longer a shock. As a result, much of the pressure may already be reflected in price.
What matters next is the yen’s reaction. If it gets stronger after the decision, risk assets (including Bitcoin) could stay under stress. But if the yen doesn’t beef up much, the market may have little left to sell. In that case, a short-term relief move isn’t off the table.
At this point, the hike itself matters less than how markets respond once it’s finally out of the way.
Final thoughts
- Bitcoin is weak of the BoJ’s expected 25 bps rate hike. Traders are de-risking early and unwinding leverage.
- BTC’s next move may depend on the yen’s reaction, not the rate decision itself.
