Rising tensions in the Strait of Hormuz have effectively halted oil tanker movements through the key shipping lane, triggering fears of real supply shortages. Shipping insurers have tightened coverage terms, raising costs and risk premiums for vessels operating in the region.

Brent crude futures spiked above $82 per barrel before settling slightly lower, driving United States Brent Oil Fund (BNO) shares up over 7% in early trading. The fund’s gains reflect direct exposure to front-month Brent contracts, which experienced a rapid price surge.

The sudden shift into backwardation—where near-term oil contracts trade at a premium to later-dated ones—enhances roll yields for futures-based funds like BNO. Should the supply risk persist, this backwardation could provide a sustained tailwind beyond spot price moves.
