Bitumen Crisis in France: BTP Sector Under Pressure

Bitumen Crisis in France: How Rising Oil Prices Are Shaking the Construction Sector

France’s construction and public works sector is facing a growing crisis—and it’s being driven by forces far beyond its borders. As tensions escalate in the Middle East and global oil supply chains come under pressure, the cost of bitumen—a critical material for road construction—is soaring.

What might seem like a distant geopolitical conflict is now having very real, very local consequences across France. From delayed infrastructure projects to rising costs for local authorities, the ripple effects are building fast.

A Global Conflict with Local Consequences

The ongoing conflict involving the United States, Israel, and Iran has triggered significant disruptions in global energy markets. At the heart of the issue lies the Strait of Hormuz—a narrow but vital shipping route through which roughly 20% of the world’s oil supply typically passes.

With traffic through this chokepoint severely restricted, oil prices have surged. Brent crude recently climbed back above $100 per barrel, a psychological and economic threshold that tends to trigger broader inflationary pressure across industries.

One of the most heavily impacted sectors? Construction—specifically, anything that relies on petroleum-derived materials.

Why Bitumen Is So Critical

Bitumen is not just another by-product of oil refining—it is the backbone of modern road infrastructure. In France, approximately 95% of roads are surfaced with asphalt, which relies heavily on bitumen as a binding agent.

France is also Europe’s largest consumer of bitumen, using over 3 million tonnes annually. That demand makes the country particularly vulnerable to supply shocks.

What makes bitumen unique?

It is derived from heavy crude oils, which are less abundant than lighter variants.
Only about 30% of global oil reserves are suitable for producing bitumen.
Major sources include regions like the Middle East and Venezuela—both geopolitically sensitive.

As a result, when supply chains are disrupted, bitumen prices tend to rise faster and more sharply than standard fuel prices.

Prices Surge as Supply Tightens

In just two months, the price of bitumen has jumped dramatically—from €450 to €650 per tonne. That’s an increase of nearly 45%, and the upward trend shows no sign of slowing.

Construction firms and suppliers are scrambling to secure stock while they still can. However, this reactive buying is only intensifying the problem, creating a feedback loop of rising demand and shrinking supply.

Broader material cost increases include:

Bituminous products: +15%
PVC derivatives: +8% to +20%
Aluminium: +12%

These increases are compounding existing cost pressures in an industry that was only just beginning to recover from years of stagnation.

A Sector Already on Fragile Ground

The French construction sector has been in a delicate position for several years, facing:

Declining new housing starts
Rising borrowing costs
Labour shortages
Regulatory pressures

Now, with raw material costs surging again, many companies are being pushed to the brink.

The Fédération Nationale des Travaux Publics (FNTP) has already raised concerns with the government, warning that without intervention, projects could stall across the country.

Government Response and Contract Challenges

In response to mounting pressure, the French government issued a circular on April 24 addressing the execution of public procurement contracts under crisis conditions.

The aim is to provide flexibility for contractors dealing with sudden cost increases. However, implementation remains complex, and many firms say the measures don’t go far enough.

Real-world impacts already visible:

In Moselle, companies have been notified of price increases starting May 1.
Cost hikes range from:
- +4% in plastering
- Up to +30% in waterproofing
In Auvergne-Rhône-Alpes, industry protests are being considered.

For many small and medium-sized enterprises (SMEs), these increases cannot easily be absorbed—especially on fixed-price public contracts.

Local Authorities Face Tough Decisions

Local councils are among the largest consumers of bitumen, as they are responsible for maintaining and upgrading road networks.

Unfortunately, the timing couldn’t be worse.

Spring and summer represent peak construction season in France, when weather conditions are ideal for roadworks. Now, many municipalities are being forced to reconsider or delay planned projects.

Potential consequences include:

Postponed road maintenance
Deteriorating infrastructure quality
Increased long-term repair costs
Budget overruns at the local level

In some cases, projects may be scaled back or cancelled entirely.

The Domino Effect Across Construction

Bitumen is just one piece of a much larger puzzle. The same geopolitical pressures driving oil prices are also affecting other essential construction materials.

Copper prices are rising due to global demand and supply constraints.
Gas price increases are expected to impact cement production, which is energy-intensive.
Transport and logistics costs are also climbing, further squeezing margins.

This creates a domino effect where nearly every aspect of construction becomes more expensive.

What Happens Next?

The outlook remains uncertain and largely depends on how the geopolitical situation evolves.

Three possible scenarios:

Short-term disruption
If tensions ease and shipping routes reopen, prices could stabilise—but likely at a higher baseline.
Prolonged crisis
Continued disruption in the Strait of Hormuz could lead to sustained shortages and further price increases.
Structural shift
Companies may begin diversifying supply chains or investing in alternative materials, though this would take time.
