Crypto markets stall as oil surges past $100 on Strait of Hormuz blockade
Bitcoin and ether retreated Monday as tensions in the Middle East triggered a spike in crude oil, forcing traders into defensive derivatives positioning.
Apr 13, 2026, 10:36 a.m.
What to know:
- Bitcoin remains trapped in a monthslong trading range after failing to clear resistance at $74,000.
- Short interest is rising for some major altcoins, like cardano, and broader market sentiment shows a preference for downside protection through put options.
- Speculative memecoins and select DeFi tokens outperformed the wider market as investors pivoted away from major assets toward high-risk niches.
The selloff came as Brent crude oil jumped back above $100 per barrel after U.S. President Donald Trump ordered a blockade at the Strait of Hormuz. The conflict with Iran has been a direct driver of risk asset price action over the past month, with U.S. equities and crypto being inversely correlated to oil and the U.S. dollar.
For now, bitcoin and the broader crypto market remain in a trading range that has persisted since early February, failing to break above $75,000 to the upside while holding firm above $63,000 to the downside.
Derivatives positioning
- Futures tied to most major tokens, including bitcoin and ether, have declined slightly over the past 24 hours. The move indicates traders are scaling back risk after President Trump ordered a blockade of the Strait of Hormuz, triggering a surge in oil prices.
- While oil prices have surged 5%, open interest (OI) in Binance’s crude futures declined by more than 1%. Activity on the decentralized platform Hyperliquid picked up over the weekend, with combined OI in Brent and WTI futures topping $1 billion.
- Futures tied to saw strong capital inflows, with open interest jumping to the most since Feb. 26. This is not necessarily bullish, as both perpetual funding rates and the 24-hour cumulative volume delta remain negative, suggesting that the inflows are being driven largely by traders chasing downside positioning or actively building short exposure rather than accumulating long positions.
- Except for HYPE, LINK, AVAX, TRX and ZEC, all top 25 coins have seen negative CVD, indicating that sell-side aggression is offsetting buy-side aggression across the market.
- A negative CVD indicates that more participants are selling by actively hitting bids than buying by lifting asks.
- Bitcoin and ether’s options-based implied volatility metrics remain low across most time frames, suggesting the market is pricing in calmer, slower price movements. The volatility curve is also fairly flat, showing no strong expectation of sudden future spikes.
- Still, downside concerns persist. BTC puts are currently trading at a 5-point or more premium across all time frames, indicating stronger demand for downside protection. ETH puts are also elevated, though to a noticeably lesser degree than BTC.
- Block flows featured call calendar spreads and straddles, with these two strategies accounting for over 50% of total activity over the past 24 hours, indicating investor preference for time decay and volatility over a clear directional bias.
