**Summary**: Reports indicate at least 25 million barrels of oil were moved yesterday through the Strait of Hormuz using small, dark tankers that then conducted ship-to-ship transfers to supertankers off Oman. This highlights an operational workaround to recent Hormuz security risks and suggests more resilience in US and allied export/import flows than headline risk might imply. The tactic tempers upside risk premiums in crude benchmarks while sustaining elevated compliance and insurance costs.

## Detail

1) What happened:
Reports [24] and [25] describe a large volume of oil—around 25 million barrels—being moved through the Strait of Hormuz using small tankers running without AIS signaling on a southern route near Oman’s coast. After crossing Hormuz, these vessels reportedly performed ship-to-ship (STS) transfers to larger crude carriers (VLCCs/supertankers), which then continue onward. This appears to be a systematic tactic to reduce risk and visibility for high-value hulls amid recent tensions and mine/drone threats in and around Hormuz.

2) Supply/demand impact:
A movement of 25 million barrels in a single day via this method is significant—equivalent to roughly 25–30% of typical daily global seaborne crude trade, suggesting this is not a marginal workaround but a substantial share of flows through Hormuz. The key point is that despite elevated security concerns, physical throughput is being maintained, reducing the probability of a sharp, sudden supply drop from the Gulf. On the demand side, there is no direct destruction, but higher transaction costs (insurance, routing inefficiencies, STS logistics) effectively raise delivered costs for some buyers.

3) Affected assets and directional bias:
- Brent and WTI: This reduces the likelihood of an acute supply shock and curbs the upside tail risk that might otherwise support a breakout move. The net effect is mildly bearish on near-term risk premium versus what would be implied by threat rhetoric alone, but overall still keeps a geopolitical premium embedded.
- Dubai/Oman benchmarks and Middle East crude differentials: The demonstrated resilience in export logistics supports continued flows, stabilizing regional spreads and backwardation structures.
- Tanker equities and freight rates: STS operations and dark traffic increase demand for smaller tankers and specialized services, supportive for product/AFRAMAX/SUEZMAX segments and for firms specializing in STS.

4) Historical precedent:
Similar covert or semi-covert routing (Iranian, Venezuelan, and Russian sanctions-era flows) has allowed substantial volumes to move despite sanctions and security risks, often muting the impact of headline disruptions on outright prices while elevating volatility and freight differentials.

5) Duration:
As long as security conditions in and around Hormuz remain tense, this workaround is likely to persist. Its impact is structurally to maintain supply while embedding higher frictional costs and opacity into Gulf oil trade, sustaining a medium-term risk premium but avoiding immediate, sustained price spikes.
