With the U.S. midterm results emerging on November 4, forecasts point to Republicans losing control of both chambers of Congress. Greater legislative checks on the White House will reshape expectations for U.S.-Iran tensions, crude oil, plastics and shrink film pricing.

A divided Congress makes large-scale U.S. military action against Iran harder to approve. While de-escalation in the near term is possible, fundamental Middle East conflicts remain unresolved. Risks around shipping through the Strait of Hormuz will not disappear, keeping a persistent geopolitical premium on crude oil. Oil is likely to trade in a wide, volatile range instead of moving steadily in one direction.

Plastic feedstock prices will follow crude swings. Prices may ease if tensions cool, yet rebound quickly with renewed friction. Weak downstream packaging demand limits how far cost gains can be passed along, so plastics rallies will lack durable fundamental support.

As a PE-based product, POF Crosslink shrink film is highly sensitive to resin costs. Near-term prices could edge lower on hopes of reduced conflict, but downside is capped. Lingering Middle East risks underpin raw material costs, and seasonal year-end packaging demand from food, beverage and consumer sectors will provide extra price support.

For converters and packagers, volatility is the new normal. A strategy of hand-to-mouth buying and partial hedging with term contracts is prudent. Market participants should monitor U.S.-Iran communications and tanker shipping data closely to manage cost exposure.
