Cheap Gas, Tight Capital: Petrochemical Expansion Remains Selective

Surging crude prices and widening feedstock spreads are steepening the global petrochemical cost curve. Cheap regional gas and NGLs may support selective integration, but not a broad new build cycle.
US ethane supply continues rising rapidly, yet global ethylene operating rates near the low-80% range still signal structural overcapacity and weak incentives for merchant cracker investment.
US ethane exports, rejection into natural gas streams, and accelerating power-sector gas demand increasingly absorb supply growth before more petrochemical capacity becomes economically necessary.
The US shale boom and China’s petrochemical expansion helped create today’s surplus capacity, shifting the industry’s challenge toward rationalization, consolidation, and disciplined capital allocation.
Otherwise, narrowing discounted crude access, widening energy spreads, packaging resilience, ethanol momentum, and slower China growth reinforce restructuring, integration, logistics control, and discipline.

Exhibit 1: Rising US ethane supply has coincided with declining global ethylene operating rates.
