Bitcoin Price Prediction: Analysts Warn BTC Could Slide Toward $70K if Bank of Japan Hikes Rates on Dec. 19

Macro analysts are cautioning that Bitcoin could decline toward $70,000 as the Bank of Japan prepares to implement a 25-basis-point rate increase on December 19.

Bitcoin analyst AndrewBTC emphasized that Japan holds the largest position in U.S. government debt, making a rate hike bearish for the Bitcoin price prediction outlook.

Historical Pattern: BOJ Hikes Trigger 20%+ BTC Drops

In a December 13 X post, the analyst examined the BTC chart and noted a consistent pattern: every Bank of Japan rate hike has preceded Bitcoin declines exceeding 20%.

The data reveals that Bitcoin dropped 23% following the March 2024 rate hike, then fell 26% after the July 2024 increase, and most recently declined 31% following the January 2025 adjustment.

With another rate decision scheduled for next Friday, the analyst believes volatility from the BOJ announcement could drive Bitcoin down to the $70,000 support level.

Historically, BOJ rate increases have strengthened the Japanese yen, elevating borrowing costs and making investments in higher-risk assets less attractive.

In conversation with Cryptonews, Ignacio Aguirre, CMO at Bitget, explained that a stronger yen “raises the risk of unwinding yen carry trades which is a move that can temporarily weigh on crypto valuations as leveraged positions reset across global markets.”

Bitcoin now faces mounting pressure as investors reduce leverage and scale back exposure amid growing risk-off sentiment.

Bitcoin Price Prediction: Weekly Chart Shows Broken Bull Structure

The weekly Bitcoin chart reveals clear momentum deterioration following repeated failures to maintain support above the $100,000 psychological threshold, which has now converted back into solid resistance.

Price has broken down from the previous distribution zone near cycle highs and is trending lower, with bearish structure validated by consecutive lower peaks and steady descent toward the upper-$80,000 region.

The RSI divergence indicator remains decisively bearish, currently positioned in the high-30s, displaying persistent weakness without any significant bullish divergence emerging.

If this momentum continues, the next major weekly support zone sits near $70,000, aligning with the prior range floor and representing the first area where substantial buying interest is likely to materialize.

A more severe correction toward the $53,000 zone cannot be dismissed if $70,000 fails to hold, potentially marking a cycle bottom.
