Mexico’s Oil Obsession Is Killing Its Petrochemical Sector

Key Takeaways

• Braskem built $500M ethane terminal in Veracruz after Pemex supply shortfall
• Pemex failed to deliver agreed ethane, halving supply by 2021
• Ethane shortage slowed Braskem’s $5.2B plant to 70% capacity
• Government omitted terminal from Plan México, highlighting policy tensions
• Supply disputes risk broader petrochemical growth in Mexico

Pulse Analysis

Mexico’s drive to become a petrochemical hub under President Claudia Sheinbaum’s Plan México has been hampered by a chronic ethane supply gap. The country’s state‑owned oil giant Pemex, tasked with feeding feedstock to downstream plants, has repeatedly missed contractual volumes, forcing producers to look abroad for the hydrocarbon that fuels polyethylene production. As the global plastics market accounts for roughly 30 % of demand, any disruption reverberates through export revenues and job creation targets set by the administration.

The most visible symptom emerged when Brazilian giant Braskem’s $5.2 billion integrated complex in Veracruz stalled at 70 % of design capacity. By 2021 Pemex was delivering only half the ethane it had promised, prompting penalties and near‑litigation. To keep the plant operational, Braskem and Pemex negotiated a $500 million ethane import terminal—Terminal Química Puerto México—completed at the end of 2025. The government deliberately omitted the project from its public rollout, underscoring the political sensitivity of admitting reliance on foreign feedstock.

The episode illustrates a structural misalignment between Mexico’s state oil policy and the capital‑intensive petrochemical sector. Without reliable domestic ethane, investors face higher costs, delayed returns, and heightened risk, discouraging the foreign capital that Plan México seeks. Policymakers must decouple Pemex’s production mandates from downstream contracts, streamline import mechanisms, and incentivize new feedstock sources. Failure to resolve these bottlenecks could stall the nation’s ambition to capture a larger share of the global plastics value chain.
