Bitcoin suffered a sharp reversal on Monday, erasing much of last week’s surge to $93,000 and triggering a broader sell-off across the crypto market. The drop pushed BTC below the critical $85,000 support level, shaking trader confidence and wiping nearly 8% from the total crypto market cap now hovering around $2.9 trillion.
At the center of the move is renewed concern over the Bank of Japan (BoJ), which signaled a possible shift in monetary policy that could have major global ripple effects.
BoJ Hints at Rate Hike and Markets React Instantly
Kazuo Ueda, the Governor of the Bank of Japan, said on Monday that the BoJ will analyze whether a rate hike is appropriate, considering domestic and global economic conditions.
This comment marked a notable shift for a central bank that has spent decades keeping interest rates ultra-low.
The market reaction was swift:
- Japanese yen strengthened sharply
- Government bond yields surged, with the 10-year yield hitting a multi-decade high of 1.876%
- Nikkei 225 and Topix slipped as investors reassessed risk
For global markets including crypto this matters because Japan is the second-largest central bank in the world, with more than $5.8 trillion in assets, even larger than the U.S. Federal Reserve’s $5.14 trillion balance sheet.
Why a BoJ Rate Hike Could Hurt Bitcoin
A Japanese rate hike would come at the exact moment the U.S. Federal Reserve is cutting rates, creating one of the sharpest monetary policy divergences in decades.
This divergence could trigger the unwinding of the yen carry trade a strategy where investors borrow cheaply in yen and invest in higher-yielding assets worldwide, including crypto.
When traders unwind carry positions:
- Yen strengthens
- Liquidity drains from risk assets
- Bitcoin, altcoins, and equities often fall
This dynamic already played out last year when early signs of BoJ tightening caused similar shocks across global markets.
Other Factors Behind Bitcoin’s Drop
While the BoJ headlines drew the most attention, other forces contributed to Bitcoin’s slide:
1. $13 Billion Options Expiry
Friday’s massive options expiry caused traders to adjust positions heading into the weekend. BTC often becomes more volatile before and after major expiries.
2. Rising Liquidations
As Bitcoin broke below support, leveraged long positions were flushed out, accelerating the decline.
3. ETF Outflows
Spot Bitcoin ETFs recorded their worst month since February, with more than $3.5 billion in outflows in November further reducing market demand.
Technical Analysis: BTC Still Showing Bearish Structure
Bitcoin’s technical picture remains weak:
- BTC formed a double top around $124,630, with a neckline near $107,270 — a classic bearish reversal pattern
- The chart shows a series of lower highs and lower lows
- A death cross has formed, where the 50-day moving average crosses below the 200-day, reinforcing the downtrend
However, not everything is bearish.
BTC appears to be forming a double-bottom pattern at $80,637, with a potential neckline at $93,065. As long as the price stays above $80,637, there is still room for a rebound.
Bottom Line
The Bank of Japan’s sudden hawkish tone may have been the spark that accelerated Bitcoin’s drop below $85,000, but the sell-off was amplified by options expiry, liquidations, and ETF outflows. Despite the decline, BTC could still find support near $80,600 a level bulls must defend to avoid deeper losses.
