Freight rates are holding firm, driven less by fundamentals and more by geopolitics. A surge in sanctioned Iranian and discounted Russian crude has filled China’s storage tanks to record highs, keeping ships busy and demand for shipping intact.
The dark fleet’s growing shadow
Beneath this stability lies a more troubling trend: the rapid expansion of the so-called “dark fleet.” More than 900 vessels, about 20% of the global crude tanker market, now operate under sanctions, false flags, or opaque ownership. These ships continue to move oil, largely undeterred, but they present immense risks. Poorly maintained, uninsured, and engaged in covert transfers, they represent not just a regulatory blind spot but a looming environmental disaster waiting to unfold.
A fragile balance at sea
The Iran-to-China logistics chain epitomizes this tension. Inefficient and clandestine, much of Iran’s sanctioned supply never directly reaches its destination, instead sitting idle in floating storage or shifting hands in shadowy transfers. Tracking these flows is an imprecise science, reliant on satellite imagery and fragmented vessel data. As global markets watch oil prices for signals of demand, shipping activity highlights a more complex truth: demand signals are distorted by geopolitics, sanctions evasion, and opaque maritime practices.
