How Washington’s Secondary Sanctions Could Reshape Iran’s Global Trade
The United States is intensifying its economic pressure on Iran by warning countries and companies that continue doing business with Tehran that they could also face American sanctions.
The threat of so-called secondary sanctions is designed to make it harder for Iran to maintain international trade and financial relationships, particularly with countries that remain important buyers of Iranian oil and other products.
What Are Secondary Sanctions?
Secondary sanctions are measures that can punish foreign companies, individuals or financial institutions for conducting certain transactions with a country or entity already targeted by US sanctions.
Unlike traditional sanctions, which primarily restrict US citizens and companies, secondary sanctions can put pressure on businesses outside the United States by threatening their access to the American financial system and markets.
Why Is Trump Threatening Iran's Partners?
The Trump administration is seeking to isolate Iran economically and cut off sources of revenue that Washington says help support Tehran's government, military programmes and other activities.
US Treasury Secretary Scott Bessent has warned that countries and companies providing an economic lifeline to Iran could face consequences as Washington expands its sanctions campaign.
Iran's Oil Trade in Focus
Iran's oil exports are a major target of the US strategy. Washington has previously used sanctions to restrict the purchase and transportation of Iranian petroleum.
Secondary sanctions create additional pressure because companies buying Iranian oil may have to choose between continuing their business with Tehran and maintaining access to the US financial system.
China Presents the Biggest Challenge
China is one of the most important economic partners for Iran and a major buyer of Iranian oil. That makes Beijing central to the success or failure of Washington's strategy.
The United States has already targeted some China- and Hong Kong-based entities connected to Iran, but Washington has so far avoided imposing the broadest possible measures against major Chinese financial institutions.
Analysts say aggressively targeting China's largest banks could create a much wider confrontation between Washington and Beijing.
How Could Secondary Sanctions Work?
If a foreign company continues a transaction covered by US secondary sanctions, Washington can potentially restrict that company's access to US financial institutions or markets.
For multinational companies, the threat can be particularly powerful. Losing access to US banking channels or the American market could be far more costly than the profits earned from continuing business with Iran.
Other Countries Could Face Pressure
Iran maintains commercial relationships with a number of countries across Asia, the Middle East and elsewhere. Businesses involved in Iranian oil, shipping, finance, technology or other sanctioned sectors could therefore face increased scrutiny.
Washington's approach effectively asks foreign governments and companies to decide whether maintaining economic ties with Iran is worth the risk of US penalties.
Could the Strategy Backfire?
The use of secondary sanctions can also create diplomatic tensions. Countries that oppose Washington's Iran policy may view the measures as an attempt by the United States to impose its foreign policy beyond its own borders.
If major powers such as China or Russia resist the pressure, Iran could continue using alternative financial and trading networks to reduce the impact of US restrictions.
Iran Faces Greater Economic Isolation
The expanding sanctions campaign could make international trade more difficult for Iranian businesses and further restrict access to foreign currency, shipping services and financial institutions.
However, the effectiveness of the strategy will depend heavily on whether Iran's major trading partners comply with Washington's demands or find ways to continue their commercial relationships with Tehran.
What Happens Next?
Washington is expected to continue monitoring Iran's international trade networks and identifying companies that help Tehran maintain access to global markets.
The response from China and other major Iranian trading partners could determine how far the United States ultimately goes with secondary sanctions.
Bottom Line
Secondary sanctions give Washington a powerful tool for extending economic pressure beyond Iran's borders. But the strategy also carries diplomatic risks, particularly if the United States attempts to force major powers such as China to completely sever their economic ties with Tehran.
