The Strait of Hormuz, a critical energy chokepoint, saw its lowest daily commodity vessel transit in three months on Monday, with just two tankers passing through, according to shipping data from shiptrackers Kpler and Vortexa. The figure was well below the 10-day average of 14, indicating a significant drop in tanker traffic. The data showed that one very large gas carrier and one very large crude carrier entered the Persian Gulf from the Gulf of Oman at 0657 GMT on Tuesday. While the number is down from the previous day, when seven vessels of various types transited the strait, it could still fluctuate as some ships had turned off their navigation transponders while passing through.
According to Marine Insight, the figures may change as some ships may have switched off their transponders. A senior market analyst at Vortexa, Xavier Tang, commented, "It remains to be seen how Iran's Persian Gulf Strait Authority can enforce compliance by such 'non-compliant' vessels." Tang further stated that if conflict escalates or vessels are attacked at the chokepoint, the impact on Hormuz transit could be significant.
Separate provisional data from Vortexa showed that Monday's oil transit at the strait was at 5 million barrels per day. On a seven-day moving average, Hormuz transits stand at around 6 million to 7 million barrels per day by August 23. Iran has taken a firm stance, blacklisting 45 tankers for violating its rules on passage through the strait and threatening action against vessels engaging in ship-to-ship transfers with them. This escalation has added to the pressure over the key waterway, six months into the Iran war.
Iran also vowed to retaliate against expanded U.S. sanctions aimed at cutting off its economic lifeline, while expressing confidence that its major trading partners would resist Washington's pressure campaign. U.S. Treasury Secretary Scott Bessent unveiled the measures on Monday but stopped short of imposing the most severe sanctions. Countries continuing to trade with Iran risked losing access to the dollar-based financial system, he warned.
Bab el-Mandeb situation
According to the data from Kpler, 30 vessels transited Bab el-Mandeb on Monday, another key chokepoint on the opposite side of the Arabian peninsula. This was broadly in line with the 10-day average and compared with 28 crossings on Sunday. While the situation in Bab el-Mandeb remained stable, the tension in the Strait of Hormuz highlights the broader implications for global energy markets.
Impact on global energy markets
The Strait of Hormuz's reduced throughput is a concern for global energy markets. The strait carries about a fifth of global crude oil and liquefied natural gas flows, according to Vortexa. Any disruption in the strait could lead to price volatility and supply chain disruptions. Ship operators in the region should remain vigilant and prepare for potential changes in the operational environment, including increased scrutiny and potential delays due to compliance checks.
What this means for operators
Operators transiting the Strait of Hormuz should anticipate delays and increased scrutiny. Compliance with Iranian rules on passage and ship-to-ship transfers is critical to avoid blacklisting and potential punitive actions. Additionally, operators should be prepared for potential attacks or other disruptions, as tensions in the region have escalated. The reduced traffic also suggests a need for optimized routing and contingency planning to ensure timely deliveries and avoid unnecessary delays.
