U.S. tanker strikes and new balance‑sheet rhetoric highlight expanding foreign‑policy toolkit
Reports of U.S. strikes on Iranian oil tankers near Jask are emerging as Treasury Secretary Bessent signals that Washington can use its balance sheet as a foreign‑policy tool. Together, they point to a U.S. strategy that leans more on financial power and pressure on energy flows to confront rivals.
Washington is sending signals that it is prepared to combine military moves and financial tools more tightly in its foreign policy, as U.S. forces reportedly strike Iranian tankers while the Treasury Department hints at a more activist role for America’s balance sheet.
On 8 September, U.S. Treasury Secretary Bessent said the United States can use its balance sheet as a foreign‑policy tool. The comment, reported without further detail, suggests a willingness to treat the government’s financial resources and policy choices as instruments that can be deployed in external as well as domestic objectives.
This statement comes as Iranian media and regional outlets report direct U.S. military action against Iranian oil shipping. Iranian television said another Iranian oil tanker was attacked by the U.S. near Jask Island in southern Iran and reported that crews from two tankers targeted by U.S. forces were being transferred to the coast of Jask. A regional source went further, claiming that three Iranian oil tankers had been struck and linking the attacks to an alleged targeting of a U.S. carrier strike group. That fuller account has not been independently confirmed, but it reflects how the situation is being framed locally.
Strikes on oil tankers affect more than immediate military balances. Tankers carry export revenues and are central to how Iran moves oil under sanctions. Targeting them is a way to curtail flows of crude and fuel associated with an adversary, putting pressure on its economy and its ability to fund regional activity.
In this context, Bessent’s reference to using the balance sheet as a foreign‑policy tool points to the other side of the pressure equation: the use of financial levers. While the comment did not spell out specific measures, the United States has long used its control over access to dollar funding and its central role in the global financial system to apply sanctions and other forms of economic pressure.
Iran has responded to the reported tanker strikes with threats of its own against energy flows. The Islamic Revolutionary Guard Corps Navy has warned oil tanker crews at ports and anchorages in Kuwait and Bahrain to abandon their vessels, saying they will be targeted, according to Iranian state media and regional reporting. Another account said Iran’s Navy had issued evacuation orders for crews on all tankers anchored or docked at ports in Kuwait and Bahrain, claiming those tankers assisted the U.S. in attacks on Iranian ships.
These warnings extend the confrontation to commercial shipping and to ports that host U.S. forces, turning the safety of international crews and the reliability of oil exports into points of leverage. They also show that Iran is prepared to respond to U.S. military and financial pressure with its own threats against the energy infrastructure of partners and allies.
The combination of tanker strikes, explicit threats to shipping and talk of using the U.S. balance sheet in foreign policy underscores how closely financial and energy tools are now intertwined with military actions. Future signals to watch include any new U.S. financial measures tied to Iranian shipping, further clarifications from Treasury about how it intends to use the balance sheet abroad, additional confirmed strikes on Iranian tankers, and any Iranian moves to carry out the threats it has made against tankers in Kuwaiti and Bahraini ports.
