Building on our earlier "Global Demand Destruction" note, which mapped how the Gulf energy shock is spreading globally and the immediate effects of rationing, price controls, and fuel shortages, another second-order disruption is quickly emerging: supply chain disruptions in critical plastic feedstocks.

Plastics are core to the modern economy, and a troubling new Bloomberg report indicates that several producers of monoethylene glycol (MEG) and purified terephthalic acid (PTA) have declared force majeure, as tanker flows through the Strait of Hormuz remain heavily disrupted.

For context, MEG and PTA are the two primary feedstocks used to produce polyethylene terephthalate (PET) and polyester fibers. These petrochemicals are critical to the production of everyday consumer goods that make life in the developed world convenient, including plastic bottles, food packaging, clothing, home furnishings, and a wide range of consumer and industrial goods.
