Maria Perrotta Berlin: The Shadow Fleet Behind Russia’s War Economy

Russia’s ability to finance its war in Ukraine remains closely tied to energy exports. In a recent episode of the Utblick podcast by the Utrikespolitiska institutet (UI), experts explored how Russia relies on a so-called “shadow fleet” to transport oil and bypass Western sanctions. The discussion examined how hundreds of aging, hard-to-trace tankers operate under false flags and opaque ownership structures to move Russian oil across global shipping routes, including through the Baltic Sea.

Maria Perrotta Berlin, Assistant Professor at the Stockholm Institute of Transition Economics (SITE) at the Stockholm School of Economics, contributed expert analysis on the economic role of this shadow fleet. In the conversation, Maria Perrotta Berlin explained how these vessels enable Russia to maintain oil exports despite price caps and sanctions imposed after the full-scale invasion of Ukraine.

Her insights highlight how energy revenues remain a central pillar of Russia’s war financing and why enforcement gaps allow sanctions to be circumvented. The episode also explored why stopping the shadow fleet is so difficult. Ships often operate under changing ownership, flags of convenience, and limited insurance oversight, making them difficult to track and regulate. The discussion further addressed the risks posed by older tankers operating in sensitive waters, including the Baltic Sea, where environmental and security concerns intersect with sanctions enforcement.
