Tankers go dark in Hormuz as escalating tensions push operators to hide transit movements
Executive summary: Oil and LNG carriers have disabled their AIS transponders while transiting the Strait of Hormuz following recent Iranian attacks on commercial ships, causing a drop in observable tanker traffic. The hidden transit increases the risk of supply interruptions and could lift war‑risk insurance costs, contributing to volatility in crude and LNG markets.
Who is involved: Vessel operators shipping crude and LNG, Iranian military forces, and maritime insurers and regulators monitoring the Strait.
Likely next: Continued attacks may lead to further AIS disabling, possible naval escorts, and urgent discussions among OPEC+ and insurance bodies about risk mitigation.
Oil and LNG tankers have begun switching off their automatic identification system transponders while crossing the Strait of Hormuz, a move driven by heightened regional tensions and recent Iranian attacks on commercial vessels. The practice reduces the visibility of ship movements, contributing to a noticeable decline in tracked tanker traffic through the chokepoint. This behavior raises concerns about potential disruptions to global energy flows and may prompt heightened scrutiny from maritime authorities and insurers.
