Middle East Conflict Triggers “Butterfly Effect” Global Market Volatility Reaches Two‑Decade High

Supply disruptions stemming from the Iran conflict have driven crude oil and other commodity prices sharply higher, prompting a surge of activity in options markets as traders rush to hedge. Producers, airlines and utilities have engaged in unprecedented hedging activity, pushing implied volatility in crude to exceptionally elevated levels while implied volatility for European natural gas has climbed to its highest point since 2023. The CME reported that its energy complex recorded a single‑day volume exceeding eight million contracts last Friday.

“This Is Clearly One Of The Largest Volatility Events In The Past 20 Years,” said Rebecca Babin, Senior Energy Trader at CIBC Private Wealth Group, noting that market participants must now monitor every indicator, including spot‑market signals not visible on trading screens. Crude oil sits at the epicenter of the turmoil. The Strait of Hormuz, which typically handles about one‑fifth of global seaborne oil traffic, has seen flows nearly grind to a halt. WTI crude surged 12% last Friday, producing a record 35% weekly gain, and prices breached USD 100 by Monday. Production cutbacks from the UAE and Kuwait exacerbated the supply squeeze. WTI options volatility reached pandemic‑era highs, and skew measures that capture the premium for calls over puts hit the strongest bullish readings since Bloomberg began compiling data in 2015.

On Friday, call‑spread trades for April with strikes between USD 120 and USD 150 changed hands, indicating that market participants were rolling positions to higher strike levels. Babin observed that volatility has risen faster than open interest, a signal that dealers are increasingly reluctant to carry risk. The extent of call buying along the term structure exceeded levels seen after last year’s U.S. strike on Iranian nuclear facilities, suggesting investors anticipate a protracted period of elevated risk. Tanvir Sandhu, Chief Global Derivatives Strategist at Bloomberg Intelligence, said this pattern implies market expectations that the disruption will not be merely transitory.

Shipping interruptions have also disrupted Middle Eastern LNG flows, delivering a fresh blow to Europe’s gas market, which is still recovering from the 2022 Russia‑Ukraine shock. The Dutch TTF gas market experienced a sharp reversal; implied volatility has more than quadrupled since the start of the year and now sits near its highest level since the summer of 2023.

The LNG disruption and price spike have produced knock‑on effects across metals and fertilizer markets. Aluminum prices jumped as supply interruptions forced producers in Bahrain and Qatar to suspend shipments. Traders’ bullish positioning had been building prior to the conflict, and option buying reached new highs on the eve of hostilities. At the London Metal Exchange, a trader purchased a large call‑spread in late February; with subsequent price appreciation, that USD 40 million wager has moved into profit. Near‑term option implied volatility has outpaced realized moves as market participants pay steep premiums to hedge against potential sharp swings.

U.S. agricultural markets have also been affected. Options traders are positioning for further corn price upside amid rising fuel costs and fertilizer supply disruptions. Last Thursday, one trader spent more than USD 5 million on call spreads with strikes between USD 5.50 and USD 6, covering 160 million bushels to protect against a potential 20% rally in September futures. Heavy activity continued on Friday, driving call option volumes to their highest levels since mid‑2024.
