Iran has dramatically ramped up its crude oil shipments in the week leading up to and immediately after the US waiver on sanctions, with over 30 million barrels departing for Asia. This includes a mix of previously blockaded crude and exports from Kharg Island, Iran's primary export facility in the northern Persian Gulf, indicating a swift re-engagement with the global market [bloomberg.com].

The easing of US sanctions, a 60-day reprieve under an interim peace deal, has reopened the US market to Iranian crude for the first time in 35 years. This policy shift, effective until August 21, exempts sales of Iranian crude oil, petroleum products, and derivatives from sanctions, and also covers associated services like banking (including US dollar transactions), insurance, and transportation [bloomberg.com, agbi.com, iranintl.com]. Analysts suggest this temporary allowance could trigger a regional scramble for market share and potentially alleviate global oil supply disruptions [agbi.com].

Iranian crude oil flows through the Strait of Hormuz have significantly increased, reaching the highest levels since the war began. Ship-tracking data showed approximately 6 million barrels on three US-sanctioned supertankers — Elva, Virgo, and Vigor — entering the chokepoint, all indicating destinations off Singapore, a known transfer point for Iranian crude often destined for China [bloomberg.com]. This surge in shipping activity coincides with ongoing negotiations between Tehran and Washington for a lasting peace deal [bloomberg.com].

Experts note that this 60-day waiver, which includes not just oil but also transportation and banking, represents a major shift in US sanctions policy. If all oil sanctions were permanently lifted, Iran, possessing the world's third-largest oil reserves, could potentially produce 3.8 million barrels per day (bpd) compared to its 2025-early 2026 production of around 3.3 million bpd [agbi.com]. The move provides significant economic incentives for Tehran to solidify the interim understanding into a permanent agreement, but also raises concerns about potential revenue strengthening of groups like Hezbollah and Hamas [iranintl.com].
