Petrochemical Supply Chain Risk: Middle East Conflict and Global Plastics

The Middle East conflict is already reshaping global supply chains – but the most significant risks are not the immediate disruptions. They are the second-order effects now building across petrochemicals, plastics, and downstream industries. While first-order impacts – energy price volatility, transport disruption, and infrastructure damage – have been rapid and visible, the next wave of disruption will be slower, less transparent, and more consequential for credit risk.

First-order effects: energy prices, transport, and infrastructure

First-order effects such as restrictions on tanker movements and damage to infrastructure have already driven volatility in energy prices, transport costs, insurance rates, and asset valuations linked to physical infrastructure. Energy markets adjust quickly to geopolitical developments, but broader pricing and credit impacts are more dependent on logistics disruption and the pace of infrastructure recovery.

Second-order effects: why Gulf petrochemicals are the hidden systemic risk

Second-order effects are harder to track but far more systemic. In addition to supplying around 25% of global oil, Gulf countries are major exporters of petrochemical derivatives. These inputs underpin the global plastics value chain, where materials such as toluene, benzene, naphtha, and propane are essential building blocks for nearly all plastic polymers – creating a critical supply chain dependency that transmits disruption across industries ranging from packaging and construction to healthcare, electronics, and aerospace.

Gulf petrochemicals and global plastics dependency

% Global Plastics Usage by Sector

This concentration creates a critical vulnerability: petrochemical supply chain disruption in the Gulf does not just raise costs, it transmits stress across nearly every major industrial value chain. Packaging is by far the main user (44.8%), especially for food, followed by Construction (18.8%) and Textiles (13.2%). Some of these can be substituted – paper-based food packaging is growing in importance, consumer goods can use natural materials for clothing, disposable cutlery, recycled rubber etc. But for many of the sectors listed above, there are no substitutes – more fossil fuels will need to be extracted elsewhere to make up the shortfall. And even if the conflict ends soon, petrochemical feedstock scarcity will take time to recover – driving an increase in input costs.

The global top 10 intermediary plastic manufacturers and distributors – Amcor, Berry, BASF, Alpla, Sealed Air, Mondi, Plastipak, LyondellBasell, SABIC and Formosa Plastics – depend on petrochemical inputs. Their consensus ratings range from ‘a’ to ‘bb’, with three in ‘bb’ categories. These firms have multiple subsidiaries, that are often rated as much as a full credit category lower, depending on geographic location and legal linkages.

Credit risk profiles across plastics-dependent sectors

The default risk profiles below cover petrochemical providers (Oil & Gas and Chemicals), downstream users such as Containers & Packaging, Transport (Automotive and Aerospace), Consumer sectors Healthcare and Textiles, Construction and Electronics, plus the Paper sector as the main substitute for plastic food and consumer packaging.

Credit Profile: Petrochemicals, Plastic Users and Substitutes - Which sectors face the highest default risk?

Two of the largest plastics users, are dominated by the ‘bb’ category: Containers (47.8%) and Textiles (42.3%). Textiles is also the highest in the ‘b’ category (21.8%). Containers are lowest (2.9%) in the ‘a’ category. Paper – a potential beneficiary – is highest (5.3%) in the ‘c’ category.

Oil & Gas has a strong credit profile, with most constituents rated as Investment Grade and a very low % in the ‘b’ and ‘c’ categories. Chemicals also have a relatively robust profile. However, global aggregates for these two industries will show strong regional divergences as the structural and logistical effects of the conflict works its way though global supply chains.

Credit Benchmark publishes Consensus data monthly, with weekly flash updates provided – these will soon start to show the scale of the impact and the speed of any recovery.

All plastics-dependent sectors face rising input costs and volatile input supplies in the short term. The following chart summarizes the tail risks for producers, intermediaries and competitors that will drive default rates as well as give scope for improvements.

Textiles are most vulnerable to rising costs, then auto/aero, then health. Packaging/containers is nearly 50% of demand, and already slightly more vulnerable than paper substitute providers who could see credit improve.

Default Risk Tails (b & c Categories) by Sector

Scenarios: conflict resolution vs. prolonged disruption

The Paper tail risk level is similar to Construction, but that gap could widen if construction faces the twin shocks of higher input costs and material volume bottlenecks. Electronics less exposed, and a small % of the global total so firms could substitute suppliers (but not materials) more easily.

The collective average ‘b’ and ‘c’ category exposures for plastics users are 17.9% and 2.5%, respectively – so more than 20% are in the very high-risk category, with the risk of a spike in defaults if the conflict is not fully resolved soon.

Chemicals generally and plastics manufacturers specifically may benefit from higher prices, but higher energy and input costs may neutralise those.

Oil & Gas are mainly a beneficiary of higher prices, and those with limited Gulf exposure will benefit from higher downstream prices and increased market shares. Exploration & Production and Infrastructure providers will especially benefit, not just from expanded capacity but also from infrastructure rebuilding in the Middle East in the future.

If the conflict is not fully resolved soon, petrochemical production will ramp up elsewhere. And sectors that provide alternatives will benefit.

If the conflict becomes protracted, transport routes and pipelines are likely to shift, and the crisis may accelerate a move away from plastics. Biotech may also benefit if they can develop alternatives to fossil fuel inputs for the petrochemical industry.
