When we talk about an oil crisis, the conversation usually starts and ends at the petrol pump. We feel the pinch immediately when filling up the tank. However, there is a far more insidious trend unfolding in the global economy: the rising cost of petrochemicals.
Petroleum isn’t just fuel; it is the primary raw material for the modern world. From the synthetic fibers in your favorite gym gear to the sterile packaging in a hospital, petrochemicals—specifically building blocks like ethylene and propylene—are the invisible ingredients in more than 6,000 consumer products worldwide.
The “Double Squeeze” on Global Manufacturing
Manufacturers are currently grappling with what economists describe as a “double squeeze.” This isn’t just about the cost of raw materials; it’s about the cost of moving them.
The first half of the squeeze is the surge in raw material prices. For instance, polyethylene—the most widely used plastic globally—has seen price surges of between 30% and 50% across parts of Asia. This directly impacts the cost of basic essentials, such as the bags used for bread and the caps on milk bottles.
The second half of the squeeze is the spike in freight costs. As global conflicts disrupt shipping lanes, the cost to transport these materials increases, adding another layer of expense that eventually trickles down to the consumer.
The Chokepoint Effect: The Strait of Hormuz
Much of this volatility can be traced back to a single geographic vulnerability: the Strait of Hormuz. This narrow shipping route between Oman and Iran is one of the world’s most critical energy chokepoints, with approximately 20% of the world’s oil supply passing through it.
Recent conflicts in the region have severely hampered shipping, with analysts estimating that close to 20 million barrels of oil per day have been affected. Because oil is the foundation for petrochemicals, any disruption here creates a ripple effect that hits factories thousands of miles away.
Why Remote Markets Face Higher Risks
Not all countries feel these disruptions equally. For nations like New Zealand, geographic isolation acts as a risk multiplier. Sitting at the far end of the global supply chain makes the country particularly vulnerable when international shipping is compromised.
The dependency is stark: about 22% of New Zealand’s polymer supply comes directly from the Middle East. An additional 56% is sourced from Asian manufacturers who are themselves reliant on Middle Eastern shipping routes.
When global supplies tighten, larger markets are typically prioritized. Smaller, more isolated nations often face the brunt of the crisis through longer shipping delays, higher freight premiums, and slower recovery times compared to their larger neighbors.

The Stealth Rise: Why You Haven’t Felt the Full Hit Yet
Many consumers are wondering why they haven’t seen a massive jump in the price of household goods despite the news of global conflict. The answer is timing.
Most products currently on store shelves were manufactured months ago using raw materials purchased at lower prices. However, as this old inventory is sold and replaced by new stock, the higher production costs will gradually flow through to the checkout counter.
Unlike the sudden shock of a petrol price hike, this inflation is gradual. It manifests as a few extra cents on hundreds of different items. Some estimates suggest that once the combined impact of fuel and goods is fully realized, households could face increases of around $55 a week.
Critical Sectors Under Pressure
While food packaging and electronics are the most obvious targets, the impact extends into critical infrastructure, most notably healthcare.
Hospitals rely heavily on plastic-based medical supplies. The production of the following items is directly tied to petrochemical availability:
- IV bags and syringes
- Surgical gloves and face masks
- Specialized medicine packaging
When the cost of these essentials rises, it puts additional pressure on healthcare budgets and the overall cost of medical care.
Frequently Asked Questions
What are petrochemicals?
Petrochemicals are chemical compounds derived from refining crude oil and natural gas. They serve as the building blocks for plastics, synthetic fibers, and various industrial chemicals.
Why does a conflict in the Middle East affect the price of toothpaste?
Toothpaste tubes and many of the ingredients inside them are made from petrochemicals. Since a huge portion of the world’s oil passes through the Strait of Hormuz, disruptions there raise the cost of the raw materials needed to make these products.
How much will my weekly spending increase?
Estimates suggest that the combined effect of higher fuel prices and more expensive petrochemical-based goods could lead to an increase of approximately $55 per week for some households.
