Key Takeaways

• Brent fell $11.50 to $92 per barrel, steepest monthly drop since 2020
• US crude inventories fell sharply, half due to strategic petroleum reserve draw
• Gasoline and diesel crack spreads double to triple seasonal averages
• Speculative short positions hit heaviest week since Iran war began
• Optimism on Hormuz reopening lifted sentiment, yet price pressure remains

Pulse Analysis

The latest week in oil markets underscores how geopolitical risk can quickly reshape price dynamics. A surge in optimism that Washington and Tehran might reach a deal to reopen the Strait of Hormuz lifted sentiment, but the underlying fundamentals kept Brent anchored near $92 per barrel. That level represents a $11.50 decline from the previous week and the sharpest monthly slide since the pandemic‑induced crash of March 2020, reminding traders that even hopeful diplomatic signals can be muted by entrenched market forces.

Inventory data added another layer of complexity. U.S. crude stockpiles contracted sharply, with the Strategic Petroleum Reserve accounting for roughly half of the draw, while commercial gasoline and diesel inventories slipped below their seasonal lows. The scarcity of refined products pushed crack spreads to lofty levels—gasoline margins hovering at about twice the seasonal norm and diesel at three times—fueling profitability for high‑utilization refineries but also signaling potential supply tightness if demand rebounds.

Meanwhile, market positioning revealed a decisive shift toward bearish bets. Speculative short positions surged to their strongest weekly level since the onset of the Iran‑related conflict in February, accounting for about half of the week‑over‑week price decline. This aggressive selling not only amplified price pressure but also eroded the previously overextended speculative long exposure. For investors and commodity traders, the confluence of diplomatic uncertainty, dwindling inventories, and heightened short interest suggests that volatility will likely persist, making risk‑adjusted strategies and close monitoring of Hormuz negotiations essential for the coming months.
