Bank of Japan’s expected rate hike – How will it affect Bitcoin and crypto traders?

The broader market sentiment has shrunk into “extreme fear” ahead of the Bank of Japan (BoJ) interest rate decision on the 19th of December. 

This was similar to “fear levels” seen in mid-November when Bitcoin broke below $100K and during Trump tariff wars in Q1 2025.

Historically, such past extreme fear readings also marked bottoms, providing exceptional buying opportunities. But will the BoJ rate hike drag BTC lower, or is it already priced in? 

Is the BoJ fear overblown?

According to Polymarket, the market consensus leaned towards a 25 basis point (bps) rate hike for the December meeting. However, for the January decision, the rate pause was more likely.  

Given that the Japanese yen is a major global funding currency, such a rate hike led to a carry trade unwind last August, triggering a BTC sell-off.

The rate hike makes it expensive to borrow in yen and forces institutions to reduce yen-based exposure, triggering broader liquidation. 

In fact, historical data showed that BTC dropped 20%-30% every time the BoJ hiked rates. Hence, the current fears were justified. 

Market positioning leans bearish

On market positioning, Nick Forster, Co-Founder of crypto options platform Derive, stated that traders were positioning for a dip below $85k. 

“On the downside, bears have accumulated substantial put exposure at the $85K strike, pointing to expectations of BTC sliding below $85K in the near term.”

The market caution extended into early Q1 2026, Forster added. 

“BTC positioning remains decisively bearish. 30-day BTC volatility has climbed back toward 45%, while skew hovers around -5%. Longer-dated skew is also anchored around -5%, signalling that traders are pricing continued downside risk through Q1 and Q2.”

At press time, just hours before the release of the U.S inflation print, BTC traded at $87K. The asset saw a liquidity grab that briefly pushed it to $90K before retracing the gains. 

Still, there were upside liquidity pools at $90.8K and $94.5K-$95K and a lower-side pool at $83K (brighter shades). These were key levels that could be tagged ahead of expected volatility.  

On ETF demand, the appetite was mixed with over $600 million outflows earlier in the week, followed by a $457 million inflow on the 17th of December, underscoring mixed signals. 

If it faces rejection at $90K again, shorting would make sense, even for non-BTC traders. Especially if BTC dominance spikes higher, as seen during the recent price decline. 

Even so, Grayscale expects a strong rebound and a new ATH in H1 2026, which would make current levels a discount buy for long-term holders if validated. 

Final Thoughts 

• BTC flashed mixed signals ahead of the Bank of Japan rate hike decision.
• Experts projected a potential dip below $85K, which could present a shorting opportunity for traders.
