Israeli strikes in recent days have hit Iran’s two main petrochemical hubs, Mahshahr and Assaluyeh, while US President Donald Trump has warned that further attacks on the country’s energy infrastructure could follow if no deal is reached by Tuesday night.
Iranian authorities said Monday that industrial facilities in the Mahshahr petrochemical zone are being evacuated ahead of Trump’s deadline.
On Saturday, April 4, Israeli forces targeted at least eight major petrochemical complexes in the Mahshahr region, along with critical supporting infrastructure, including power plants that supply electricity to the industrial zone.
Two days later, similar strikes hit the vast petrochemical facilities in Assaluyeh, the center of Iran’s South Pars gas and petrochemical operations.
Although the full extent of the damage remains unclear, Iranian officials have acknowledged that operations in both regions have been halted.
Mahshahr accounts for approximately 28 percent of Iran’s petrochemical production, while Assaluyeh contributes more than 48 percent. Together, the two hubs represent roughly three-quarters of the country’s total petrochemical output.
Iran’s petrochemical industry is the second-largest source of export revenue after crude oil. The country has a nominal production capacity of about 95 million tons per year, although actual output is closer to 75 million tons due to persistent shortages of electricity and natural gas.
Around half of this production—valued at approximately $13 billion annually—is exported, accounting for more than one-fifth of Iran’s non-oil exports.
The shutdown of these facilities therefore represents more than a temporary industrial setback. It directly threatens one of Iran’s most important sources of foreign currency earnings.
If the damaged infrastructure cannot be restored in the medium term, the second-largest producer of petrochemicals in the Middle East could even face shortages.
Over the past decades, Iran has invested an estimated $70 billion in developing petrochemical infrastructure. In the event of severe damage, rebuilding these facilities would pose a major financial and technical challenge.
Given the constraints imposed by sanctions, limited access to international capital and broader economic pressures, Iran is unlikely to have the resources required for rapid reconstruction.
Even if external financing were secured, restoring production capacity would take years, and possibly more than a decade.
Petrochemical plants are highly complex systems that depend not only on physical infrastructure but also on stable energy supply, advanced technology and efficient logistics networks—all of which are currently under strain in Iran.
The strikes on petrochemical facilities come alongside recent attacks on major steel plants in Isfahan and Khuzestan, which together account for roughly half of Iran’s steel output. Taken together, the pattern suggests a broader strategy aimed at weakening Iran’s industrial backbone rather than targeting isolated sectors.
The timing of these strikes is particularly significant given Iran’s pre-existing structural weaknesses.
In recent years, the country has faced chronic shortages of natural gas, electricity and refined fuels, forcing many industries to operate well below capacity. These constraints have already reduced industrial output and increased production costs.
At the same time, Iran’s logistics sector suffers from deep inefficiencies. According to World Bank data, the country ranks near the bottom in regional logistics performance, second only to Afghanistan. This limits Iran’s ability to reroute supply chains, manage disruptions or quickly recover from large-scale damage to infrastructure.
The combined effect of these factors could push Iran into a deeper economic crisis. A sustained disruption in petrochemical exports would significantly reduce foreign currency inflows, putting additional pressure on the national currency and exacerbating inflation.
Ultimately, the burden of this crisis will fall disproportionately on ordinary Iranians who are already struggling with high inflation, energy shortages and rising unemployment.
If Trump follows through on his threat, the conflict could move further into the economic domain, reshaping the trajectory of Iran’s economy and potentially sending shockwaves through regional—and even global—energy markets.
