Hormuz Crisis Forces Oil Market Participants to Reassess Positions

The war between the U.S. and Israel against Iran has significantly disrupted the oil market, causing sharp price fluctuations and forcing market participants to quickly adjust their positions and risk management strategies.

A report by the Oxford Institute for Energy Studies (OIES) titled 'Shifting Oil Market Positioning During the Strait of Hormuz Crisis' highlights the changes in the oil market amid the crisis. Disruptions to oil flows through the Strait of Hormuz were particularly significant, affecting not only the availability and destinations of physical oil supplies but also the functioning of the oil derivatives market.

According to the report, open interest in oil futures fell sharply as financial speculators reduced their positions amid significant price volatility, higher margin requirements, and growing pressure to reduce positions due to tighter value-at-risk (VaR) limits. In contrast, oil options have become a more sought-after instrument for expressing and managing risks associated with market movements during overnight trading.

The use of short-term option contracts has increased significantly, particularly among producers, trading companies, refiners, and consumers (PMPU). The PMPU's net position in Brent became significantly shorter during the first three months of the war, after which it began to shift in the opposite direction. This trend generally coincided with changes in crude oil trade flows, as refiners sought to offset supply disruptions caused by the closure of the Strait of Hormuz.
