Iran's Stance and US Warnings
Iran has issued a stark warning, promising a “crushing, punishing and devastating” response to any new economic threats from the United States. This declaration follows Washington’s pledge to impose what it describes as the toughest financial penalties in history, aimed at intensifying pressure on the Iranian leadership.
Iranian Armed Forces Chief of Staff Major General Ali Abdollahi affirmed the nation's readiness for retaliation across land, sea, air, air defense, and cyberspace. Meanwhile, Parliament speaker Mohammad Baqer Qalibaf suggested that the US and Israel, having concluded they cannot prevail in direct military confrontation, are now resorting to economic and “cognitive” warfare.
The warnings were issued after US Treasury Secretary Scott Bessent announced forthcoming details of new measures. President Donald Trump has also explicitly threatened economic consequences against any country providing “any type of lifeline” to Iran, escalating the global stakes for Tehran's commercial allies.
Key Nations in Iran's Trade Network
The impending US sanctions could significantly impact several of Iran’s major trading partners:
China: Iran's Largest Oil Buyer
- China stands as Iran’s primary oil customer, with over 80% of Iran’s exported oil directed to the country.
- Chinese independent refiners have capitalized on discounted Iranian crude, with estimates suggesting China purchased an average of 1.38 million barrels per day in 2025.
- The US Treasury has already sanctioned a Chinese independent refinery over Iranian oil transactions and warned Chinese banks about potential secondary sanctions.
UAE: A Major Import Hub
- In 2024, the UAE accounted for 30% of Iran’s imports, valued at $21 billion, and 13% of its exports.
- Non-oil trade between the two nations reached $6.6 billion that year.
- However, the UAE recently suspended financial and economic transactions with Iran until further notice, signaling a potential shift in trade dynamics.
Turkey: Energy and Goods Exchange
- Turkey imports Iranian natural gas and exports manufactured goods to Iran.
- Bilateral trade typically ranges between $5-6 billion annually, with Turkey exporting approximately $3 billion to Iran.
- Iran supplies 13% of Turkey’s total gas imports.
Iraq: Vital Energy and Consumer Goods
- Trade between Iraq and Iran surpassed $10 billion in 2025, primarily driven by Iranian food and consumer goods exports.
- Iraq also pays Iran an estimated $4-5 billion annually for natural gas, crucial for its electricity generation.
- New US sanctions could complicate Baghdad’s ability to make these energy payments.
Oman: Trade and Diplomatic Role
- Trade between Oman and Iran totaled $1.5 billion in 2025, with $345 million recorded in the first four months of 2026.
- Oman has historically served as a mediator between Iran and various international partners, including the United States.
Pakistan: Expanding Border Trade
- Formal trade between Pakistan and Iran has been growing after years of sanctions-related disruptions, while informal trade is estimated at around $4 billion.
- Both countries have committed to expanding bilateral trade to $10 billion.
India: Humanitarian and Commercial Ties
- India-Iran trade reached $1.63 billion in FY2025/26, with Indian exports, mainly cereals, tea, coffee, and spices, accounting for $1.3 billion.
- New Delhi has consistently maintained that these exports are humanitarian in nature.
Armenia and Azerbaijan: Regional Connections
- Iran represented 3.6% of Armenia’s trade turnover in 2025, with approximately 20% of Armenia’s foreign trade transiting through Iran.
- Azerbaijan-Iran trade amounted to $312.6 million between January and June 2026.
Global Implications of Escalating Sanctions
The US strategy to impose “tremendous economic consequences” on countries supporting Iran signals a significant escalation in geopolitical tensions. These measures aim to isolate Iran financially but risk disrupting established trade relationships and potentially creating economic ripple effects across several key global markets, forcing nations to reconsider their commercial ties with Tehran.
