Middle East tensions continue to influence global energy markets. Reports indicate that the geographical location data of some vessels in the Persian Gulf show significant anomalies in position and speed, suggesting intensified signal jamming following Iran's recent attacks on neighboring countries. Vessel tracking data reveals that approximately 120 ships appear clustered in a ring-shaped formation about an hour's drive inland from Abu Dhabi, UAE, with speeds close to 50 knots but no change in position. Another group of about 12 vessels is clustered near the land border between Oman and the UAE, with speed data showing over 100 knots. Such clustering of vessel positions inland and abnormal speed data likely result from interference with ships' geolocation broadcasts, known as signal jamming. Previously, the UAE stated it had activated its air defense systems last week to counter missiles and drones launched by Iran, marking Iran's first attack on the UAE in nearly a month. The anomalies in vessel positioning and speed data indicate a resurgence of signal disruption. Mark Douglas, an analyst at maritime intelligence agency Starboard Maritime Intelligence, noted that following the latest attacks, the UAE and other Gulf nations likely activated electronic warfare systems. He stated, "Shipping activities, particularly Automatic Identification System (AIS) data, have been affected." AIS is a system that automatically broadcasts vessel dynamic information via radio technology. Although the current intensity of electronic interference is lower than at the onset of the conflict, the clustering of abnormal vessel positioning suggests that previously eased signal disruption has intensified again. Increased signal jamming complicates real-time traffic data analysis in the Persian Gulf and the Strait of Hormuz, which is crucial for understanding energy flows. Currently, ship captains have begun adopting strategies such as turning off transponders to protect themselves from attacks. On Sunday, a cargo ship was attacked in the region. By Monday, shipping in the Strait of Hormuz was nearly at a standstill, with only two tankers making a rare passage into the Gulf of Oman. One of them, the very large crude carrier Agios Fanourios I, carrying Iraqi crude oil, was destined for Vietnam. The escalation has drawn attention due to the strategic importance of the Strait of Hormuz, which handles about one-fifth of global crude oil and liquefied natural gas shipments, making it one of the most critical "chokepoints" in the global energy supply chain. The back-and-forth situation in the Middle East has become a core driver of recent oil price volatility. U.S. President Trump recently stated that Iran's response to the U.S. ceasefire proposal was "completely unacceptable." Influenced by this news, Brent crude rose 3.7% to $105.07 per barrel on Monday, while WTI crude increased 4.30% to $99.52 per barrel. Analysts at ING noted, "It was expected that the market would grow increasingly weary of the overwhelming news flow and back-and-forth. However, oil prices remain highly sensitive to noise surrounding Iran, highlighting the significant impact of ongoing supply disruptions in the Persian Gulf."
