Trump wants more economic pressure on Iran. What are his options?
WASHINGTON, Aug 16 (Reuters) - U.S. President Donald Trump on Friday vowed to hit Iran hard economically, a day after Treasury Secretary Scott Bessent said that Washington would impose measures on Tehran that have "never been seen" as soon as next week.
The United States, United Nations and European Union have applied sanctions, implemented trade embargoes and frozen assets since the late 1970s over Iran's nuclear program, human rights violations and support for militant groups.
Since the Iran war began in February, Washington has levied additional maritime, energy and financial sanctions and started a naval blockade.
Data from the U.S. Treasury Department's Office of Foreign Assets Control (OFAC) shows the agency has imposed sanctions on more than 1,000 people, vessels and aircraft since Trump began his second term.
Recent measures have targeted Iran's shadow oil fleet; shipping insurers; entities and people enabling Iran's acquisition of weapons; and digital exchanges, freezing an estimated $500 billion in Iran-linked cryptocurrency.
Experts say the Trump administration also can try these options:
SANCTIONS ON CHINESE 'TEAPOT' REFINERS
Chinese independent refineries known as "teapots" account for a quarter of Chinese refinery capacity. They operate with narrow and sometimes negative profit margins.
China buys more than 80% of Iran's shipped oil, according to 2025 data from analytics firm Kpler. Independent refiners absorb much of this trade, exposing them to so-called secondary measures that penalize entities helping a primary sanctions target.
Past U.S. sanctions have deterred larger independent refiners from buying Iranian oil. But the independent refineries are somewhat immune since they have little exposure to the U.S. financial system, sanctions experts say.
SANCTIONS ON CHINESE BANKS
OFAC has imposed secondary sanctions on smaller China- and Hong Kong-based entities accused of processing billions of dollars in Iranian oil and helping to fund weapons procurement.
Treasury has warned two larger Chinese banks they could face secondary sanctions if Iranian funds were found moving through their systems, but has stopped short of designating them.
Hitting those two banks, which U.S. officials have not publicly identified, or imposing other sanctions could have a chilling effect on bigger financial institutions, sanctions experts said, although they warned it could also trigger retaliatory actions by Beijing.
Trump administration officials have sought to play down tensions between Washington and Beijing ahead of an expected meeting between Trump and President Xi Jinping later this year. They worry that China could curtail exports of critical minerals that are essential to advanced technology production at a time when the U.S. and Western allies are still trying to develop their own supplies.
'WHACK-A-MOLE'
The United States could continue targeting Iranian individuals and entities, as well as others in China and the Gulf, that are helping Tehran evade sanctions to collect revenues for its war effort.
Treasury recently issued sanctions against firms that are springing up to facilitate Iran's trading of oil revenue for imports. But such measures amount to a "whack-a-mole" approach that has not altered Iran's behavior, said Brett Erickson, managing principal of Obsidian Risk Advisors, noting that Tehran simply creates new entities to replace them.
Miad Maleki, a sanctions expert with the Foundation for Defense of Democracies, said Bessent was likely signaling a sharpened enforcement push against oil shippers, purchasers and currency exchangers who help Iran pay for its imports.
Further aviation sanctions were also possible, aimed at degrading Iran's ability to move trade now that the U.S. has blockaded shipping via the Strait of Hormuz, he added.
LAND BLOCKADE
Some U.S. and Israeli officials have floated the prospect of a land blockade, which would require assistance from Iran's neighbors: Iraq, Turkey, Pakistan, Afghanistan, Turkmenistan, Azerbaijan and Armenia.
The Trump administration has varying degrees of closeness with all those countries except Afghanistan, but that border is mountainous and extremely difficult to patrol anyway.
Trump may have leverage over Pakistan, which recently sought a $10 billion currency swap line from Treasury, and Turkey, which is seeking to rejoin the U.S. F-35 warplane program.
A land blockade could increase pressure on the Iranian people by halting their imports of food, energy and textiles, but experts say such a move would be difficult to execute and might not result in protests or internal pressure.
SECONDARY TARIFFS
Trump has repeatedly threatened tariffs on goods from countries that do business with Iran, although the Supreme Court struck down the legal basis for such taxes.
The Senate passed a sweeping Russia sanctions bill last week that included new Iran sanctions and would give Trump new tariff powers that he could potentially use against countries that aid Iran's commerce and weapons procurement.
That legislation must still pass the U.S. House of Representatives, which could prove challenging given widespread concerns among Democrats and some Republicans about the tariff measures.

核心判断
制裁是法律文本、执法网络和市场替代三者共同作用。若第三方执行弱或替代结算充足，名义强度可能高于实际冲击。
证据与数据口径
需要核对财政部文件、受制裁实体、伊朗出口与船运跟踪、折价、库存和主要进口方数据。媒体列举政策选项不代表已经实施。
传导路径
能源出口限制影响原油供应预期和地区折价。
船舶、保险和结算限制提高航运与贸易成本。
美元流动性与地缘风险溢价传导至油价、黄金、汇率和通胀预期。
市场已计价与可能忽略的变量
市场可能迅速计价制裁升级，容易忽略豁免、规避网络、战略库存和其他产油国余量。
情景分析
基准：措施逐步收紧但执行不均，油价风险溢价温和上升。
乐观：外交缓和或供应替代充足，实际市场冲击有限。
谨慎：能源与航运限制有效压缩出口，并与地区冲突叠加推高油价。
