Bitcoin suddenly plunged below $83,000 tonight. The root cause was not internal to the crypto industry, but rather a surge in oil prices driven by tensions in the Middle East, with prices breaking above the $100 mark and triggering a chain reaction of sell-offs across global stock, bond, and crypto markets.

【Macro Turmoil and a Liquidation Storm】
According to reports by Cointelegraph and Reuters, shipping restrictions in the Strait of Hormuz and escalating geopolitical tensions sent Brent crude surging to $102 per barrel today, while WTI crude also touched $91. The energy price spike directly drove up global inflation expectations, pushing the yield on 30-year U.S. Treasury bonds to 5.73%—a nearly 24-year high not seen since 2002—while the 10-year yield climbed to 5.36%.

As rising Treasury yields drained liquidity from markets, the S&P 500 and gold both plunged, and the crypto market was unable to escape the fallout. According to CoinGlass monitoring data, total crypto liquidations across the market surged to $969 million over 24 hours, including $644 million in long liquidations. Bitcoin () plunged from an intraday high of $85,543 to a low of $82,776, decisively breaking below the key support of its 21-day moving average (around $83,850).

(What this means for readers: When the risk-free return on U.S. Treasuries surges to a high not seen in more than 20 years, global institutional investors will prioritize reducing their liquidity exposure. In the short term, safe-haven flows are also unlikely to support crypto prices.)

【Tradable Assets and Market Structure】
As for tradable assets, this pullback is essentially a liquidity flush triggered by a “macro spark” and intensified by a “cascade of leveraged positions.” According to CryptoQuant data, since late September, Bitcoin futures open interest (OI) has fallen nearly 10%, from $28.8 billion to $26 billion. This reflects a lack of appetite for chasing prices in the derivatives market, with bullish investors lacking sufficient spot-buying momentum to support the market.

Technically, Bitcoin’s 4-hour RSI fell to 32.2 after the sharp decline, entering short-term oversold territory. However, on the daily chart, the 50-day moving average remains above the 200-day moving average, so the medium-term structure has not yet fully turned bearish. Market focus has shifted to the $81,100–$81,500 range below, where the daily 50% Fibonacci retracement level aligns with the cost-basis support for short-term holders.

(What this means for readers: Highly leveraged short-term bulls have already been largely flushed out. At this stage, blindly chasing shorts or making a heavily weighted attempt to buy the dip carries very high risk. For now, macro interest rates—not crypto-specific news—are driving price action.)

【Forward-Looking Views That Can Be Verified】
Here is a forward-looking view that can be tested: if Brent crude remains above $100 and the 30-year U.S. Treasury yield fails to form a technical top at 5.75%, Bitcoin may further test the strength of support at $81,100. Conversely, the “confirmation signals” to watch when assessing whether the market has truly bottomed are not a sharp rebound after futures liquidations, but two hard indicators: first, whether Bitcoin spot trading can produce a high-volume candle close above $83,850 (the 21-day moving average); and second, whether futures open interest (OI) gradually recovers without being accompanied by large-scale liquidations. Until these signals appear, any rebound should be viewed as a test of liquidity.

(What this means for readers: To judge whether the market has stopped falling, don’t focus on bullish or bearish calls on social media. Keep a close eye on whether Treasury yields have peaked and whether spot buyers are stepping in again above key moving averages.)
