As the U.S.-Iran conflict escalates and the Strait of Hormuz remains closed, economists and industry leaders are warning of a looming inflation wave that extends far beyond rising gasoline prices. The disruption in this vital shipping chokepoint, through which nearly all petrochemical exports from the Gulf region pass, is driving up costs for essential raw materials like naphtha, which are the building blocks for plastics used in everything from food packaging to medical supplies. According to experts, these increases could permeate consumer goods worldwide, hitting shelves with a delay but with significant force.
The Strait of Hormuz, a narrow waterway between Iran and Oman, handles about 12% of the world's petrochemical production, totaling around 150 million tons annually from Gulf Cooperation Council states including Saudi Arabia, Iran, Qatar, Bahrain, Kuwait, Oman, and the United Arab Emirates. Of the 193 active petrochemical complexes in the Middle East, roughly 79% are concentrated in Saudi Arabia, Iran, and Qatar, with Saudi Arabia accounting for 75% of the region's production capacity. The closure, triggered by heightened hostilities in the ongoing war that began earlier this year, has halted shipments of key feedstocks such as benzene, butadiene, ammonia, styrene, and naphtha, all derived from oil and natural gas.
Stanislav Krykun, CEO of DST-Pack, a Poland-based packaging manufacturer that supplies clients across Europe and the United States, is already feeling the pinch on his factory floor. "Our plastic suppliers in China have raised prices by roughly 15% recently, and they've pointed to higher raw material costs and general market uncertainty as the reason," Krykun said in an interview. His company produces molded plastic components for products like Advent calendars, which are now in early production stages for the 2026 Christmas season. These seasonal items often feature intricate plastic trays for chocolates, and the cost recalculations are underway for dozens of ongoing projects.
Krykun noted that the price hikes aren't hitting immediately due to the supply chain's built-in lags. "It's quite gradual," he explained. Companies that locked in pricing before the recent developments can proceed at old rates, but "all new orders placed over the past couple of weeks are already being quoted at higher prices." He added that packaging must be produced, shipped to manufacturers, filled, and then distributed to retailers, meaning consumers might not see the changes on shelves for weeks or months.
The broader implications of these petrochemical shortages are staggering, touching nearly every aspect of daily life. Tom Seng, an assistant professor of professional practice in energy finance at Texas Christian University's Ralph Lowe Energy Institute, emphasized the ubiquity of these materials. "The uses of petrochemicals are wide-ranging and, essentially, impact everything we use and consume. It would be hard to identify something that didn't have an oil or natural gas-based component unless it was constructed entirely of wood," Seng said. He highlighted the automotive sector, where "the amount of plastic used in auto and truck manufacturing alone is huge."
Jeff Krimmel, founder of the energy consultancy Krimmel Strategy Group, pointed to the diverse applications of these feedstocks. "There are so many of these everyday goods that will be impacted," Krimmel said, listing textiles, detergents, food, and beverages as particularly vulnerable. He stressed the role of naphtha, a liquid-based oil derivative that's the primary source from Middle East fields with no easy substitutes. "Naphtha is really important; it is a richer, more liquid-based feedstock with a slate of outputs that cascade across the economy," Krimmel explained. Even if the conflict ends soon, he warned, normalizing supply and demand will take time, and prolonged hostilities would compound the issues.
Packaging needs to be produced, shipped to the manufacturer, filled with product, and only then distributed to retail. So any price changes typically become visible on shelves with some lag rather than instantly.
This quote from Krykun underscores the delayed but inevitable consumer impact, as brands scramble to adapt. In response to rising costs, companies are simplifying packaging designs—such as skincare brands opting for less complex boxes or phone accessory makers reducing internal components. "We're seeing brands make very practical adjustments," Krykun observed. For instance, boxed chocolates might see simplified internal layouts. However, these changes aren't quick; redesigns involve development, testing, and approvals that can take weeks or months, forcing many to place orders at elevated prices in the interim.
The petrochemical industry has weathered multiple shocks in recent years, from the Covid-19 pandemic to the Russia-Ukraine war, Red Sea disruptions, and now the Strait of Hormuz crisis. Atsi Sheth, chief credit officer at Moody's Ratings, described the current situation as part of a volatile pattern. "Moody's has been calling out that there is a supply shock—too much supply, not enough demand," she said, noting that global oil companies ramped up production in response to China's increased output, leading to oversupply and downward rating actions on producers due to eroding margins and debt capacity.
Sheth predicts a rapid shift once existing stocks deplete. "The inference we are making is that this will ultimately feed into consumer price inflation. Food, clothing, and other retail goods will hit those at the lower end of the income scale," she said. This comes as the industry grapples with the Hormuz closure's direct threat to $733 billion in raw feedstocks, intermediates, and finished products—representing 22% of global supply for items like ethylene, propylene, butadiene, benzene, toluene, xylenes, methanol, glycol, MTBE, epoxides, acetic acid, acrylic acid, PTA, acrylonitrile, and melamine—that flow through the Gulf.
Peter Swartz, chief science officer and co-founder of supply chain analytics firm Altana, highlighted the downstream ripple effects. Altana's data indicates these petrochemical flows impact $3.8 trillion in goods, from toothpaste to towels. "The long-term effect is here. Every business is now planning for a more uncertain future and investing in diversification, and that is cost-additive," Swartz said. He noted a multiplier effect, as petrochemicals feed into tens of trillions of dollars in goods that cascade into even more products, with "no magical easy substitution for these products."
The conflict's origins trace back to escalating tensions in early 2026, when U.S. military actions against Iranian targets prompted retaliatory measures, including the mining and blockade of the Strait. Reports from the U.S. Department of Defense indicate that naval forces are working to clear the waterway, but progress has been slow amid ongoing skirmishes. Iranian officials have claimed the closure is temporary and defensive, while U.S. spokespeople describe it as an act of economic warfare aimed at global destabilization.
Consumer advocates and economists are urging preparedness for widespread price increases. In the U.S., where plastic packaging accounts for a significant portion of retail costs, families could see hikes in everything from holiday treats to household cleaners. Krimmel warned that no consumer should expect quick relief, as the supply chain's interconnectedness amplifies the disruption.
Looking ahead, industry watchers anticipate that even a swift resolution to the war won't prevent inflation from building through the end of 2026 and into 2027. Diversification efforts, such as sourcing from alternative regions like the U.S. Gulf Coast or Asia, are underway but come with their own premiums. As Krykun put it, order volatility is rising, with brands balancing cost management against the need to maintain product integrity. The world economy, it seems, has one unexpected word for the Hormuz crisis: plastics.
