Global Cost Curve Compression: The Quiet Repricing of Chemical Competitiveness

China’s latest retaliatory tariff threats increase the risk of a supply chain reset, holding the potential to realign global petrochemical flows structurally, erode US margins, and shift net benefits to Europe and Asia Ex-China.
The potential shift of US feedstock exports and chemicals away from China risks creating a flatter global cost curve, flooding alternative markets, and favoring regional players with logistical and greater policy flexibility.
Canada’s push to boost propane exports to Asia—enabled by its strategic West Coast port access—shows how secondary suppliers can swiftly capitalize on geographic advantage and geopolitical shifts amid trade tensions.
For US producers of methanol and polymers—especially those who banked on China-bound growth—this is a wake-up call: demand doesn’t reroute as easily as molecules and new capacity may face unforeseen challenges.
Otherwise, the report highlights compressed polymer margins, cost curve convergence, volatile biofuel dynamics, and water risks in critical minerals—reminding us that resilience depends on adaptability and scale.

Exhibit 1: If China advances with a blanket tariff on US imports; net benefits may flow to Europe & Asia Ex-China.
