• Iran's capacity for sustained drone attacks threatens months of shipping disruptions in the Strait of Hormuz, even as missile supplies face limits.
  • Energy markets are reacting sharply, with oil and gas prices surging and a 70% drop in tanker traffic as shipping firms reroute around Africa.
  • The crisis, triggered by US-Israeli strikes on Iran, has escalated with tanker hits, regional refinery shutdowns, and heightened risks of wider conflict.

Iran could keep the Strait of Hormuz unstable for months using drones, according to assessments from regional security analysts, as the 2026 crisis deepens with repeated attacks on shipping and energy infrastructure. The situation, sparked by US-Israeli Operation Epic Fury airstrikes on February 28 that targeted Iranian nuclear and military sites, has seen Tehran launch hundreds of missiles and over 1,000 drones in retaliation, with the capacity to produce up to 10,000 drones monthly. While most attacks are intercepted, even limited strikes have slowed shipping through a route carrying about 20% of global energy supply, driving oil and gas prices higher and forcing major shipping lines to suspend transits.

In the latest developments, Iran's Islamic Revolutionary Guard Corps (IRGC) has launched drone attacks on oil tankers, including the ATHE NOVA, which remains burning after two drone hits, and the MKD VYOM, hit by a drone boat that killed one Indian crew member and caused a fire in the engine room. VHF warnings from the IRGC have threatened to block the strait, though no formal blockade has been declared. According to people familiar with the matter, shipping firms such as Maersk (MAERSK-B.CO), Hapag-Lloyd (HLAG.DE), CMA CGM, and Japanese lines have halted Hormuz transits, rerouting around Africa and leading to a 70% traffic drop with over 150 tankers anchored offshore. Efforts to secure safe passage have hit a snag, with insurers pulling back and war-risk premiums spiking.

Energy markets are already reacting, with US WTI crude up 7.6% to $72.12 per barrel and Brent crude rising 8.6% to $79.11, while European natural gas prices surged 40% amid a shutdown of Qatari gas production. Saudi Arabia intercepted drones targeting its Ras Tanura refinery, now shut, and reported additional attacks, adding to regional tensions. Without a deal to de-escalate, analysts warn that even small, repeated strikes—or the potential use of sea mines—could prolong disruptions and keep global markets on edge, echoing the impacts seen from Houthi attacks in the Red Sea. Traders fear a broader Middle East supply halt, with one energy executive noting, "We're bracing for sustained volatility as Iran leverages its drone capabilities."

The political context remains fraught, with Iran retaliating for the assassination of Supreme Leader Ali Khamenei by striking Israeli cities, US bases in the UAE, Qatar, and Bahrain, and claiming a drone attack on the US embassy in Riyadh. Hezbollah rockets from Lebanon have added to the escalation, though attempts to reach Iranian officials for comment were unsuccessful. Regional sources indicate that Iran's drone strategy, built on technology from Russia and battle-tested in Ukraine where over 60,000 drones have been launched, allows for prolonged harassment despite missile limits. Short-term, experts predict continued instability with oil potentially staying above $80 per barrel if traffic cuts persist, while long-term risks include a wider war affecting Saudi and Qatari output. As one maritime analyst put it, "This isn't just a flashpoint—it's a slow-burn crisis with drones as the new frontline."
