A dramatic escalation of tensions between the United States and Iran has sent shockwaves across the Persian Gulf region, after Washington unveiled sweeping new economic sanctions targeting Tehran just one week after a 60-day negotiation window for a new peace deal and the reopening of the Strait of Hormuz expired.
With the U.S. having ruled out direct military intervention to resolve its long-running conflict with Iran, Treasury Secretary Scott Bessent announced the new measures on Monday, designed to fully isolate Iran’s already battered economy. While Bessent stopped short of rolling out the harshest possible penalties, he issued a stark warning: any nation or entity that continues to trade with Iran faces the risk of being locked out of the U.S. dollar-dominated global financial system. Notably, the Treasury did not release specific details of compliance timelines or the full scope of penalties for non-compliance, leaving global markets and trading partners in a state of uncertainty.
Under the new executive action, the U.S. Treasury has blacklisted 60 distinct entities, individuals and vessels linked to Iranian trade, while also suspending a series of general licenses that previously permitted limited activities including certain cross-border remittance payments to Iran. The department also confirmed it is coordinating with international allies to dismantle illicit financial and trade networks that Tehran has relied on to generate revenue in the face of previous sanctions rounds.
Tehran has struck a defiant public posture in response, with Iranian officials claiming the country’s long-standing trading partners will push back against U.S. pressure. But the reality of Iran’s economic outlook grows more dire by the day: just last week, the governor of Iran’s Central Bank confirmed that crude oil exports – the country’s primary source of government revenue – have dropped to zero amid an ongoing U.S. naval blockade of Iranian ports. This collapse has pushed an already crippled economy to the brink.
For years, a handful of regional and global powers including China, Iraq, Pakistan, Turkey and several Gulf states have maintained limited commercial ties with Iran, even as the Trump administration, which began its second term in 2025, has imposed sanctions on more than 1,000 individuals, vessels and aircraft linked to Tehran. Data from 2025 compiled by analytics firm Kpler shows China purchases more than 80 percent of all Iranian crude oil shipped globally. Notably, the new sanctions announced Monday do not target any Chinese financial institutions accused of facilitating this oil trade, and Bessent declined to comment on whether such measures are being considered for the future.
While Iranian Economy Minister Ali Madanizadeh insists the country is “fully prepared” to weather the new punitive measures and that trading partners will resist U.S. pressure, ordinary Iranian citizens are already bracing for deeper hardship. State data published by Iran’s Energy Optimisation Organisation shows the country currently faces a daily gap of 15 million litres of petrol, against a total national demand of 135 million litres. “For ordinary Iranians, this is no longer merely a question of declining living standards or rising poverty, but a daily struggle to afford food, medicine, housing and other basic necessities,” explained Mehran Haghirian, executive director of research at UK-based think tank Bourse and Bazaar, in an interview with Middle East Eye.
The core question now hanging over the region is whether this new round of economic pressure will force Iran’s leadership to make concessions at the negotiating table, or push the country toward open military confrontation with the U.S. and its regional allies. In anticipation of the U.S. sanctions announcement, Mohsen Rezaei, the newly appointed secretary of Iran’s Supreme National Security Council, issued a blunt threat of retaliation over the weekend: Tehran is prepared to target U.S. oil and commercial firms operating in the Persian Gulf and beyond. Rezaei also warned Gulf Arab states against joining Washington’s “economic war”, warning that if they align with the U.S. campaign, “not a single drop of oil will leave the Persian Gulf and the Strait of Hormuz” – a disruption that would send shockwaves through global energy markets.
Washington’s strategic bet is that intensified economic pressure will weaken the Islamic Republic, force it back to nuclear and security negotiations, and break its control over the critical Strait of Hormuz, through which roughly 20 percent of the world’s daily oil shipments pass. But Tehran has made clear it is prepared to accept direct military confrontation rather than concede to U.S. demands. This dynamic has created what experts call an extremely dangerous spiral for the entire region. “This creates a dangerous dynamic in which the US tries to regionalise Iran’s economic isolation while Iran tries to further regionalise the costs of that same isolation,” explained Sina Toossi, a senior fellow at the Centre for International Policy.
Even as Tehran maintains a defiant military posture, some top Iranian officials have acknowledged that economic collapse threatens the future of the republic more than military confrontation. Last week, following reports that oil exports had ground to a halt, Iranian Parliament Speaker Mohammad Bagher Ghalibaf acknowledged: “No matter how much military power we possess, if the people are hungry and we lack financial turnover, economic growth, and national production, we will not survive.” For Iran’s new leadership, the core challenge remains striking a delicate balance between making strategic concessions to win sanctions relief and preserving the country’s security priorities, all while preventing further economic collapse that could threaten domestic stability.
The escalating tensions have already prompted a key shift from one of Iran’s most important trading partners: the United Arab Emirates. Just days before the U.S. announced its new sanctions, the UAE declared it would suspend “all activities, commercial exchanges, and financial transactions” with Tehran until further notice. According to World Trade Organization data from 2024, the UAE accounted for 30.6 percent of all Iranian imports and was Iran’s third-largest export market, absorbing 12 percent of Iranian exports worth more than $7 billion annually, putting total bilateral trade at an estimated $20 billion per year.
The Emirati foreign ministry only cited “regional escalation” as the reason for the move, which came shortly after the UAE defence ministry claimed Iran launched two ballistic missiles toward Emirati territory – an allegation Tehran has repeatedly denied. Analysts say the suspension is likely a signal that Abu Dhabi is aligning more closely with Washington as it ramps up pressure on Iran, though repeated attacks on commercial shipping operated by Abu Dhabi National Oil Company (ADNOC) in the Strait of Hormuz likely also played a role.
Abu Dhabi has long attempted to balance engagement with Tehran and alignment with Washington, using a mix of incentives and pressure to encourage de-escalation. Justin Alexander, director of Khalij Economics, notes that the suspension is likely to be phased in, and could be reversed if Iran agrees to guarantee safe passage for Emirati shipping through the Strait. Still, the move has sparked speculation that it could mark a permanent shift in the UAE’s posture toward Iran.
Tensions between Tehran and Abu Dhabi rose dramatically after the U.S. and Israel launched military operations against Iran in February 2025, when the UAE faced more than 2,700 Iranian ballistic missile and drone attacks in retaliation. While an April ceasefire eased open hostilities, the UAE has continued to deepen its security and economic ties with both the U.S. and Israel in the months since. Javad Heiran Nia, director of Persian Gulf Studies at Tehran’s Shahid Beheshti University, argues that the UAE’s long-term approach to Iran will depend on the final terms of any peace agreement between Washington and Tehran, but could point to a more hostile long-term posture. “In such a scenario, the UAE will try to position itself within a security buffer beyond the reach of Iran and its affiliated armed groups in the region, while quietly advancing its cooperation with Israel regarding Iran,” he explained. Ultimately, the new U.S. sanctions have raised the stakes for all parties, leaving the region on the edge of a new and unpredictable phase of conflict.
