Unsaturated Polyester Resin (UPR) Price Trend Q2 2026

In Q2 2026, the global Unsaturated Polyester Resin (UPR) market has been witnessing a strong upward trend as escalating geopolitical tensions between the United States and Iran and disruptions to shipping through the Strait of Hormuz have driven Crude oil and key feedstock costs higher, including Styrene Monomer (SM), Maleic Anhydride (MA), and Phthalic Anhydride (PA).

Higher freight charges, marine insurance premiums, and tighter raw material availability have increased production and import replacement costs, supporting firmer UPR prices across major producing and importing regions.

The UPR Price Chart has captured this sustained upward trajectory throughout most of the quarter. Toward the end of the quarter, the US-Iran ceasefire and the agreement to reopen the Strait of Hormuz have started easing crude oil, feedstock, and logistics pressures.

The UPR Price Index has begun reflecting this normalization, with June 2026 prices correcting across most regions as feedstock costs and freight rates have gradually stabilized, while buyers have increasingly shifted toward need-based procurement.

The prices of Unsaturated Polyester Resins (UPR) are influenced by various factors, including raw material costs, supply and demand dynamics, production capacity, and market competition. One of the most significant factors affecting UPR prices is the cost of key feedstocks, such as styrene and polyester resins. Additionally, global demand for UPRs in industries like automotive, construction, and marine also plays a role in shaping prices. If demand for UPR-based products increases due to growth in construction or automotive sectors, this can lead to price hikes. Conversely, economic slowdowns or a decrease in demand for certain applications could put downward pressure on UPR prices. Supply chain issues, such as disruptions in the delivery of raw materials or manufacturing delays, can also significantly impact UPR prices.

Feedstock prices have a direct and substantial effect on UPR prices. The primary feedstocks for UPR production are styrene and unsaturated polyesters, and any fluctuations in the prices of these materials can lead to changes in UPR prices. For example, if the price of styrene increases due to a rise in the cost of crude oil or disruptions in the supply of petrochemicals, the production cost of UPR will also rise, prompting manufacturers to increase UPR prices. Similarly, changes in the availability or cost of other raw materials such as resins, curing agents, and additives can also have an impact on UPR pricing. As raw materials account for a significant portion of production costs, any volatility in feedstock prices often results in corresponding changes in UPR prices.

Inflation has a notable influence on UPR prices due to its impact on overall production costs and market conditions. As inflation rises, the cost of raw materials, energy, and labor also tends to increase, directly affecting UPR manufacturers. With higher operating costs, manufacturers may pass on these increases to consumers, leading to higher UPR prices. Additionally, inflation can lead to an increase in the costs of transportation and logistics, which further contributes to price hikes. However, inflation can also influence demand for UPR-based products. In times of high inflation, consumers and industries might reduce spending, leading to a potential decrease in demand for certain products that rely on UPRs. In such cases, even though production costs may rise, the overall demand reduction might keep prices stable or cause them to decrease. Therefore, the relationship between UPR prices and inflation is shaped by a combination of cost-push and demand-side factors.
