US plastic suppliers are struggling to absorb the escalating costs of raw materials, which is signaling upcoming price increases across a range of consumer goods, from food to automobiles. The wholesale prices for plastic resins and materials saw a significant 14% surge last month, reaching an almost four-year peak. This increase is primarily attributed to the Iran war, which has disrupted the supply of crucial components. This situation is pushing manufacturers like Shawn Gross, who supplies molded parts for automotive and heating systems, to a critical point.

The global economy is experiencing ripple effects from the US and Israeli attack on Iran and the subsequent closure of the Strait of Hormuz in late February. This conflict caused sharp increases in prices for fuel, energy, fertilizers, and other industrial products. Although an interim deal is expected to reopen the strait, the disruptions continue to impact the supply chain, adding costs at every level and exacerbating the financial strain on consumers already grappling with years of inflation. A significant challenge noted is the rising cost of packaging, partly due to increased energy prices and disruptions in the supply of naphtha, a key ingredient in plastics, with one-third sourced from the Middle East. The price of naphtha alone has jumped by 30% since the war began.

While Asian and European markets are more exposed to these rising prices and supply chain disruptions, the impact is now reaching the US. Plastics, which are ubiquitous in products from snack packaging to refrigerator parts and are about 98% derived from fossil fuels, are now subject to these higher costs. Whirlpool Corp., for example, anticipates higher resin prices to boost its raw material costs in the latter half of the year. Similarly, Cava Group Inc. has factored higher energy-related costs, including polyethylene expenses for food, beverage, and packaging, into its annual guidance. Retailers are also bracing for inflation in non-food categories as elevated resin costs begin to affect the cost of goods, especially if oil prices remain high, impacting items with plastic components like polyester and cotton. Consumers are already facing increased costs for necessities, with the consumer-price index rising by 4.2% in May, marking the highest inflation rate in over three years, predominantly driven by energy costs.
