Hormuz Attacks Surge as Oil Flows Rebound

What's happened

Vessels transiting the Strait of Hormuz have faced a surge in attacks, with data showing nine to twelve strikes in a week across October. Shipping remains disrupted as Iran continues to press transit limits, while global energy flows edge back toward pre-war levels amid heightened security concerns.

What's behind the headline?

Brief

• Attacks on tankers in and around Hormuz have intensified, with weekly totals reaching the highest since the conflict began.
• Oil flows are recovering toward pre-war levels, but maritime insurance costs and transit risk remain elevated.
• The U.S. and allied navies continue escorting vessels, signaling ongoing security commitments in the region.

What this means

• Shipping routes through Hormuz are under renewed pressure, potentially keeping freight and insurance costs high for months.
• Iran's strategy appears to be leveraging disruption to demonstrate influence over global energy markets.
• Markets should monitor oil loadings and tanker schedules as asset flows respond to risk signals.

Forecast

• Attacks will likely persist or increase in the near term, sustaining elevated risk premiums for tanker operators and oil shipments.

How we got here

The Strait of Hormuz remains a critical chokepoint through which a sizable portion of the world’s oil and LNG travels. Since February, warfare has dramatically increased maritime tensions, with Iran signaling it will pursue ships beyond Hormuz. Recent weeks have seen a spike in attacks, drone activity, and harassment, affecting vessel movements and oil loadings from key producers.
