Brent crude futures surged past $100 per barrel for the first time since late 2024, jumping 4.2% to settle at $101.12 as Iran dramatically escalated military operations in the Persian Gulf and a new hardline leader vowed to maintain pressure on Strait of Hormuz shipping lanes.

Market Context

The move higher came amid a broader risk-off in global markets as traders priced in supply disruption risks. The IEA confirmed the conflict represents the largest supply disruption in history, surpassing previous Middle East disruptions. Energy sector ETFs saw heavy inflow, with the Energy Select Sector SPDR Fund (XLE) trading 18 million shares—well above its 12-million-share average daily volume.

Analysis

The options market reacted with pronounced volatility expansion. The CBOE Oil Volatility Index (OVX) spiked 23% to 42.3, its highest level since the early 2024 conflict escalation. Implied volatility on at-the-money Brent options expiring in two weeks surged to 38%, while the risk reversal (25-delta call minus put) widened to +8.2, indicating strong bullish bias among options traders.

Institutional flow data showed significant call buying in the $105-$115 strike range, with notable accumulation in XLE March $95 calls. Market makers reported elevated gamma exposure on long oil positions, suggesting dealers are forced to buy futures as spot moves higher. The combination of supply fear and short-covering in crude oil futures—total open interest sits at 2.1 million contracts near record levels—creates potential for exaggerated moves in either direction.

Retail participation increased notably, with zero-DTE crude oil options seeing 340,000 contracts trade, the highest single-day volume on record. The so-called "gamma squeeze" potential has traders watching dealer positioning closely.

Key Numbers

- Brent crude settled at $101.12, up 4.2% ($4.08)

- WTI crude rose 3.8% to $97.84 per barrel

- OVX volatility index jumped 23% to 42.3

What to Watch

Traders should monitor the $105 level as key resistance, with puts clustering around $95-$98 providing support. Any further Iranian escalation could push OVX toward 50, while a de-escalation may see rapid vol compression. The April OPEC+ meeting looms as a potential catalyst, with speculation growing the cartel may reverse production cuts. Watch for changes in dealer gamma positioning and any unusual activity in weekly expiries.

The options market is pricing a 32% probability of $110+ by month-end, based on the distribution implied by current vol skew. Any headlines about strait interference would likely trigger another wave of call buying and potential short squeeze dynamics.
