China's independent refiners, known as "Shandong teapots," benefit significantly from sanctioned oil. They purchase discounted crude from countries like Venezuela, boosting their margins and supporting local economies. This trade is often conducted in renminbi, furthering China's goal of de-dollarization in energy markets.

Sanctions on major Russian oil companies don't halt exports but instead push them into opaque channels. Russia uses independent traders and restructured ownership to create "unknown" cargos, removing sanctioned company names from documents. This model, proven with smaller firms, maintains export volumes while obscuring the oil's origin.
Russia has dramatically shifted its oil trade away from the U.S. dollar, with only 5% of exports now settled in USD, down from 55% in 2022. While this circumvents direct financial sanctions, Russia remains vulnerable as key logistics like freight and insurance are still dollar-linked, increasing costs and complexity.
A potential restart of Venezuelan oil is significant because it is a heavy, diesel-rich crude that has become scarce as U.S. shale dominates supply with light oil. U.S. Gulf Coast refiners, built decades ago, are specifically configured to process this heavy crude, creating a unique high-margin opportunity.
The primary impact of U.S. sanctions on Russian oil is not a reduction in supply but a compression of profit margins. Russia is forced to offer deeper discounts, estimated at $3-$5 per barrel below pre-sanction levels, to compensate buyers for increased logistical and financial risks, ensuring export flows remain stable.
Each time the U.S. uses financial sanctions, it demonstrates the risks of relying on the dollar system. This incentivizes adversaries like Russia and China to accelerate the development of parallel financial infrastructure, weakening the dollar's long-term network effect and dominance.
China loaned Venezuela over $60 billion but halted funding due to extreme corruption. Instead of making new strategic investments, China now focuses on asset recovery, accepting oil shipments simply to pay down the massive outstanding debt. This highlights the limits of 'debt trap diplomacy' in utterly dysfunctional states.
Contrary to popular belief, China's influence in Venezuela is primarily economic, not strategic. They are a key consumer of oil but do not control the industry or the government. Russia, in fact, has a more embedded military and strategic presence in the country.
Political shifts in Venezuela could restart exports of heavy, sour crude. This is a direct benefit for specialized U.S. Gulf Coast refiners (like Valero and Marathon) built to process this specific type of oil, potentially lowering their input costs and boosting profit margins, creating a distinct set of winners in the energy sector.
By consolidating influence over Venezuelan and Guyanese reserves alongside its own, the U.S. could control nearly a third of global oil reserves. This would fundamentally reshape energy geopolitics, diminishing the influence of powers like Saudi Arabia and potentially keeping oil prices in a lower range.
Faced with geopolitical uncertainty in key supplier nations, China employs a dual strategy for energy security. It has built a massive oil stockpile providing 120 days of cover for supply disruptions. Concurrently, it's rapidly electrifying its transport sector to reduce its long-term dependence on imported oil.
