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

Bitcoin's bull run faces a potential gut-check from an unlikely source: Tokyo.

The Yen's Shadow Over Crypto

Forget the Fed for a moment. The real short-term threat to Bitcoin's price might be brewing at the Bank of Japan. A surprise rate hike on December 19th could send shockwaves through global liquidity—and crypto is first in line to feel the pinch. Analysts are sketching out a path where that shock sends Bitcoin tumbling toward $70,000.

The Liquidity Lifeline Gets a Squeeze

Cryptocurrency markets feast on loose monetary policy. The BOJ has been the world's last holdout, a fountain of cheap yen that sloshes into risk assets everywhere. Turning that tap off, even a little, pulls a foundational prop from under the market. It's a classic 'risk-off' trigger, and digital assets often lead the sell-off.

A Test for the New Regime

A drop to $70K would represent a sharp correction, but not a catastrophe. It would shake out weak hands and test the conviction of the new institutional money that's supposedly here for the long haul. Consider it a stress test for Bitcoin's current valuation—one dictated by central bankers, not crypto Twitter.

The irony is thick enough to cut with a samurai sword. After years of being called 'detached from fundamentals,' Bitcoin's next major move could hinge on the most fundamental force in traditional finance: central bank policy. The decentralized future, it seems, still watches the old masters very closely. Get ready for a volatile week—the fate of the market might just be decided by a room full of suits half a world away, proving once again that in finance, the only free lunch is the one you pay for with volatility.

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.

Bank of Japan is set to hike rates +25 bps on Dec 19. Japan = largest holder of US government debt

Look at the $BTC chart:

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-.

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, aligning with the prior range floor and representing the first area where substantial buying interest is likely to materialize.

A more severe correction toward thecannot be dismissed if $70,000 fails to hold, potentially marking a cycle bottom.
