The US Treasury Department has issued formal notices to shipping companies and their operators, requesting detailed information about a group of about 100 vessels believed by intelligence and regulatory sources to have moved Russian oil in ways that circumvent Western sanctions. The disclosure, drawn from informed sources, underscores Washington’s ongoing effort to track energy shipments tied to Moscow’s oil trade and to tighten the enforcement of price caps designed to limit Russia’s oil revenues. The notices are issued within a framework intended to illuminate the intricate routing and ownership structures often used to mask the origin of crude destined for global markets. [Citation: Reuters]
Meanwhile, officials at the Office of Foreign Assets Control have sent similar inquiries to firms across roughly 30 countries. Observers describe this as the sharpest escalation since the initial sanctions on Russian oil exports. The objective remains straightforward: reduce Russia’s ability to fund or profit from its oil sales in response to the wider geopolitical situation and ongoing Ukraine-related actions that shaped Western sanctions policy. The notices emphasize a coordinated effort to scrutinize intermediaries and trading desks that may facilitate or conceal sanctionable oil flows. [Citation: OFAC]
Reuters reported that the US Treasury declined to publicly confirm the launch of a formal probe or any investigations connected to the information in question. The absence of confirmation is interpreted by some experts as a sign of sensitivity around ongoing enforcement actions and the desire to maintain operational secrecy while new data is gathered and analyzed.

Earlier, in remarks related to broader sanctions policy, Janet Yellen, speaking in her role as a senior U.S. official, signaled the possibility of additional sanctions if Chinese entities or institutions are found to be supporting Russia’s military and economic activities tied to the Ukraine crisis. In discussions with senior Chinese officials, the deputy prime minister was reminded that the United States views material support to the Russian military-industrial complex as a red line. The message was clear: if such support continues or expands, further penalties and measures could be announced, with a focus on disrupting supply chains, financial transactions, and access to technology that could bolster Russia’s war economy. These statements reflect a consistent U.S. stance that allied cooperation and enforcement will intensify in response to the evolving geopolitical landscape. [Citation: U.S. Policy Brief]
In a broader frame, Russian officials have presented their position by stressing that sovereignty and strategic resilience remain firm in the face of sustained sanctions. Lavrov, frequently cited in official briefings, has asserted that Moscow has learned to adapt to foreign-led economic pressure, pursuing a path that safeguards core national interests while navigating the limits imposed by Western sanctions. Observers note that Moscow’s portrayal of sovereignty and economic autonomy forms part of a longer-running narrative designed to sustain domestic support and deter external pressure, even as sanctions tighten financial conditions and complicate access to international markets.
