The War with Iran Reopens a Silent Risk for European SMEs
The first week of March sent a signal Europe knows all too well. Following the onset of attacks by the United States and Israel against Iran on February 28, 2026, the Strait of Hormuz became a near-total choke point for energy trade. Approximately 20 million barrels a day of crude and derivatives pass through this passage, accounting for about one-fifth of global consumption. Additionally, volumes of LNG from Qatar and the UAE, approximating 20% of worldwide LNG trade, also transit through. The immediate effects were striking: on March 2, oil prices surged 8%, while gas in Europe jumped by 20%. Days later, the April TTF gas contract touched €70/MWh on March 9 (the highest since January 2023), subsequently moderating to €60/MWh. Brent crude hovered around $102/barrel on the same day, with estimates cited by CNBC indicating an increase close to 50% since the beginning of 2026.
On a macro level, the discussion mirrors that of 2022: inflation, interest rates, and competitiveness. At the micro level, which is where SMEs operate, the issue becomes more specific and uncomfortable: energy is no longer a "stable" input and instead becomes a critical factor in product design and customer behavior. When gas and fuel prices soar, the purchasing thresholds, price sensitivity, and willingness to wait shift. This reconfiguration primarily impacts those who cannot withstand volatility with financial scale.
The Shock is Not Just Price; It's the Sequence of Decisions it Triggers
What makes this crisis dangerous is not just a single figure but the intertwining effects. The conflict disrupted flows through Hormuz, and concurrently, Qatar suspended LNG operations on March 2, with its Energy Minister predicting a return within a "weeks to months" timeframe. During the same period, Russia communicated that LNG exporters would redirect shipments initially intended for Europe to Asia. This triple movement creates a classic pattern: fewer molecules available in the Atlantic, Asia competing for spot cargoes, and Europe paying premiums when it most needs to replenish inventories.
Europe enters into this competition with a specific fragility: lower storage levels. At the end of February 2026, there were 46 bcm in storage, down from 60 bcm in 2025 and 77 bcm in 2024. This matters because the market doesn’t purchase gas “for today”; it buys expectations of sufficiency for the upcoming winter, and the summer replenishment window (April-August) is short. If prices rise now, part of that increase is purely present-based, while another part signals a need to induce “demand destruction,” as warned by Andy Sommer of Axpo: prices must rise enough for industries and generators to cut back on consumption and to ensure adequate restocking.
For an SME, this sequence translates into three operational frictions. First, cost uncertainty: it’s not just about paying more, but not knowing how much more for how long. Second, imperfect pass-through: raising prices for the end customer often encounters delays, renegotiations, or loss of volume. Third, interactions with credit: analysts cited by CNBC suggest that if prices do not normalize by June, the ECB may raise rates, increasing financial costs just when liquidity is needed to sustain working capital.
The management temptation is to treat this as “a storm to weather.” A more useful approach is to recognize that the shock rewrites consumer and corporate customer tolerance maps. In behavioral terms, expensive energy creates a more pragmatic buyer: they cut extras, postpone renewals, accept less variety, and seek predictability. This opens windows for simpler proposals and clearer contracts.
Energy Inflation Redefines the Product the Customer is Willing to Engage With
At Sustainabl, we spend considerable time observing how people and businesses buy advancements, not objects. In an energy shock, the prioritized “advancement” shifts. In 2022, the lesson was harsh: both domestic and industrial customers stopped paying for features and began paying for continuity.
Now, the scenario is similar, albeit nuanced. Europe is less dependent on Russian gas than before, but it remains exposed to global oil and LNG prices. Economists cited by CNBC describe a clear mechanism: a 10% increase in oil can add 0.3% to overall inflation in the Eurozone, with potentially nonlinear effects through gas. Under scenarios with Brent around $100 and gas at about €60/MWh, pressures sufficient enough could compel the ECB to consider rate hikes.
For an SME, these figures translate into micro-decisions from buyers:
- In B2C, households that see fuel prices nearing €2 per liter (in Frankfurt, gasoline €2.12; diesel €2.19, according to cited data) adjust mobility, leisure, impulse consumption, and discretionary spending. There is less tolerance for surcharges, diminished patience for “surprise services,” and increased affinity for flat rates, bundles, and guarantees.
- In B2B, corporate customers revisit their calculators: they ask for review clauses, push for payment terms, and demand more consolidated deliveries to cut logistics. They also prioritize suppliers that can absorb complexity.
Herein lies a not-so-glamorous yet powerful opportunity: simplification. In crises, large companies often respond with layers of conditions, indices, surcharges, and endless menus of options. This protects the P&L but translates operational anxiety onto the customer. The SMEs that thrive aren’t those that promise “the best price” but those that design an offering that the customer understands and can budget.
This could mean fewer catalog references, fewer urgent deliveries, less customization, and more focus on availability and consistency. In energy-intensive or highly logistical sectors, the buyer is “contracting” for one thing: that their operational life does not turn into a daily fire due to uncontrollable variables.
What an SME Can Do Without Creating Financial Magic
CNBC notes that Europe might have already incurred €1.4 billion in losses from gas spikes just in the first week of the conflict. For an SME, the relevant number isn’t that total but the elasticity of its margin in response to each hike in the TTF or diesel prices. And since no one can control Hormuz, competitive advantage turns internal: contracts, cost structure, and the design of the commercial promise.
I see four realistic and executable moves that do not rely on “betting” for market calm.
First, turn uncertainty into rules. If your business has direct exposure to gas or fuel, commercial conditions must contain a clear review mechanism, with fixed periodicity and an explicit index (even if it's a public benchmark like TTF or Brent, as applicable). The alternative is to renegotiate manually every month, which consumes the sales team and erodes trust.
Second, review the product from the marginal cost, not from pride. In energy shocks, many companies persist in pushing lines that were only profitable with cheap energy. The hard decision is to temporarily discontinue what drains cash or requires high energy consumption without return. This isn’t “cutting”; it’s safeguarding the capacity to serve what the market pays for.
Third, make time a feature. When inputs grow more expensive, the customer values predictability even if it takes longer. Offers with slower standard delivery, but with stable pricing and conditions, can outperform “fast” competitors that later add surcharges. Practically, this reduces logistical urgency and allows for grouped production and distribution.
Fourth, liquidity discipline amid the double blow of energy and rate increases. If the shock prolongs and the ECB tightens, the cost of financing inventory and receivables rises. For many SMEs, the most profitable improvement lies in not selling more but in collecting earlier and buying better: shortening cycles, reviewing early payment discounts, and negotiating supply windows.
None of this eliminates geopolitical risk, but it does alter who absorbs it. The company that lets the risk “float” within its operations becomes a hostage to the market. The one that encodes it into its business model and integrates it into its offer design reduces perceived volatility for the customer and preserves margins.
Competitive Advantage in 2026 Will Be Determined by Operational Trust
The shock of 2022 taught us that when the TTF skyrockets, customers cease to reward sophistication and start to value continuity. In 2026, the pattern reemerges with an added element: lower inventories entering the refilling season and a global competition for LNG when Qatar is sidelined for “weeks to months.” This makes especially valuable the supplier who does not promise heroics but offers stable service with clear rules.
For SME leadership, the strategic reading is straightforward. The risk is not just paying higher energy prices. The risk is getting trapped between fast-rising costs and customers adjusting their demand, requiring predictability, timelines, and explanations. Companies that endure these kinds of episodes often share one characteristic: they convert macro uncertainty into repeatable micro-decisions.
The learning about consumer behavior is clear. In an energy inflation scenario, the user is not contracting variety or extra features: they are contracting the reduction of friction and the continuity of their daily and operational life, even if that involves simpler products and stricter conditions.
