Strategic Realignment in Hormuz Strait Oil Tanker Operations
The oil tanker sector in the Strait of Hormuz is undergoing significant changes amid rising tensions. Although there has been an increase in the number of vessels departing the Gulf, this does not indicate a return to normal operations. Instead, it highlights a shift towards more secretive and fragmented energy market practices.
Discrepancy Between Shipping Data and Actual Flows
Despite public data showing low transit volumes—averaging only three oil tankers per day through the strait—actual shipping activities appear to be increasing. This discrepancy suggests that many transportation activities are not being captured by traditional monitoring methods.
"Covert Shipping" Emerges as a Dominant Strategy
The practice of disabling the Automatic Identification System (AIS) to avoid detection has become common among tankers. This method, similar to tactics used by Iran to circumvent sanctions, allows vessels to operate in "silent" mode, reappearing only after significant delays. Vortexa estimates that around 65% of laden outgoing tankers employed this strategy in May, leading to reduced market visibility and complicating the assessment of crude oil flows.
Additionally, the inventory of "floating storage" on tankers has decreased, indicating a gradual recovery in outward shipments despite ongoing shipping challenges.
Evading Surveillance Routes and Geopolitical Implications
Identifying the routes of these "shadow tankers" is complex. Some may follow corridors approved by Iran, while others might navigate routes along the coast of Oman, potentially supported by the U.S. Navy. There are also indications that some vessels may pay tolls to Iran for safe passage. This precarious situation could change rapidly, especially if U.S.-Iran negotiations remain stalled.
For oil-producing nations, every exported cargo is crucial for alleviating fiscal pressures, and for Asian buyers, it represents a vital supply source. A stable shipping environment is essential for recovery, as producers face challenges in restarting significant production capacities.
Logistical Bottlenecks Hamper Recovery
Logistical issues are hindering recovery efforts, particularly the return of empty tankers to the Gulf for reloading. Without a stable flow of tankers, onshore storage facilities risk reaching full capacity, limiting production recovery. Currently, there is an imbalance between laden tankers departing and empty vessels returning, compounded by rising insurance costs and cautious shipowner behavior.
Uncertainty in the Long-Term Landscape
Even if diplomatic efforts lead to a formal reopening of the strait, the operational dynamics are unlikely to revert to previous norms. Iran may seek to maintain greater control over the strait, potentially introducing tolls that could disrupt traditional shipping routes. This situation may compel Gulf oil producers to explore alternative transportation methods or even consider military options to alter the status quo.
The current state of "covert flow" reflects a fragmented and risk-laden market environment, where any temporary relief may not be sustainable.
