ISN SPECIAL REPORT: “From Oil to Bread – How the US–Iran War Is Hitting Europe’s Supermarket Shelves”

The escalation of the US–Iran war in 2026 is no longer a distant geopolitical conflict. It is rapidly becoming a direct cost-of-living crisis for European consumers, with supermarket prices already rising — and set to worsen significantly in the months ahead.

What began as a military confrontation has evolved into a full-scale economic shock, transmitted through energy, fertiliser, logistics, and ultimately, food.


The Trigger: Energy Shock Turning Into Food Inflation

At the centre of the crisis lies the disruption of the Strait of Hormuz — one of the most critical arteries of global trade.

  • Around 20% of the world’s oil supply flows through this route

  • Shipping disruption has caused oil prices to surge sharply

  • Gas prices in Europe have nearly doubled in days

The consequence is immediate:
Energy becomes more expensive → production costs rise → transport costs increase → food prices follow.

As one economist warned:

“The longer this lasts, the more significant the shock”

This is not theoretical. It is already happening.


From Fuel to Food: The Domino Effect

Food inflation is not driven by supermarkets alone. It is driven by the entire system behind them.

1. Fertiliser Crisis

The Middle East is a key supplier of fertiliser inputs. Disruption is already pushing prices higher.

The CEO of fertiliser giant Yara, Svein Tore Holsether, issued a stark warning:

“Could severely impact global food supplies”

Urea prices have already surged dramatically, threatening crop yields worldwide.


2. Agriculture Under Pressure

European farmers are being squeezed:

  • Gas prices (used for heating greenhouses) have surged

  • Fertiliser costs rising

  • Imports becoming more expensive

This means less production, higher costs, and lower margins — all feeding into supermarket pricing.


3. Transport & Imports

Europe imports a significant share of its food.

With oil prices rising:

  • Shipping costs increase

  • Refrigeration costs increase

  • Distribution becomes more expensive

Economists warn that even basic logistics inflation will push grocery prices higher across the board


What Will Become More Expensive?

The impact is not limited to one category — it is systemic.

According to retail and supply chain analysts:

  • Fresh vegetables: up to +15% expected

  • Dairy (milk, cheese, butter): rising due to feed and energy costs

  • Bread: impacted by fertiliser and grain production

  • Cooking oils, coffee, seafood: highly exposed to global trade disruption

This is not a temporary spike — it is the beginning of a broader inflation wave.


Supermarket CEO Reality: Quiet Alarm

While few supermarket CEOs have publicly panicked, their messaging is becoming increasingly cautious.

Executives across global retail are signalling three key concerns:

1. Cost Pressure Cannot Be Fully Absorbed

Retailers absorbed inflation during earlier crises. This time, capacity is limited.

Margins are already thin. The ability to shield consumers is weakening.


2. Supply Chains Are Becoming Unpredictable

The war has introduced a level of volatility not seen since the Ukraine crisis.

Retailers are facing:

  • Delayed shipments

  • Contract uncertainty

  • Sudden price renegotiations


3. A Warning Behind Closed Doors

Industry insiders indicate a growing concern:

This is not a short-term shock.
It is a structural inflation phase linked to geopolitics.


Europe: The Most Exposed Region

Europe is particularly vulnerable for three reasons:

1. Energy Dependence

Unlike the United States, Europe relies heavily on imported energy.

Energy price spikes directly translate into:

  • Higher production costs

  • Higher retail prices


2. Import Reliance

Countries like the UK import up to 40% of their food supply

Any disruption in global trade hits supermarket shelves quickly.


3. Weak Consumer Spending Power

Even before the war, European consumers were under pressure.

Now:

  • Purchasing power is falling

  • Inflation is returning

  • Economic growth is slowing


The Consumer Impact: A Second Cost-of-Living Crisis

For households, the consequences are clear:

🛒 Smaller baskets

Consumers will buy:

  • Fewer items

  • Cheaper alternatives

  • More private label


💸 Higher weekly bills

Even modest increases across categories create a cumulative effect.

A typical family shop could rise significantly over months.


🔄 Behavioural Shift

Expect:

  • More discount shopping

  • Reduced brand loyalty

  • Increased price sensitivity

This trend is already visible — and will accelerate.


Will It Get Worse? Yes.

All indicators point in one direction: further pressure ahead.

  • Oil markets remain unstable

  • Fertiliser shortages are worsening

  • Agricultural output is under threat

The Bank for International Settlements has warned that prolonged conflict could intensify economic stress globally

And in food terms, the timeline is delayed:

👉 Energy shock → production cost → supply chain → supermarket shelf

This means the worst price increases may not yet have arrived.


ISN Final View: A War That Ends at the Checkout

The US–Iran war is not just a geopolitical event.
It is a supply chain war with global consequences.

For supermarkets:

  • Margins will tighten

  • Price pressure will intensify

  • Competition will become more aggressive

For consumers:

  • Food will take a larger share of income

  • Choice will narrow

  • Affordability will dominate decisions

The uncomfortable truth is this:

The battlefield may be thousands of miles away —
but the impact is already visible in Europe’s supermarket aisles.

And for millions of households,
the real cost of war will be paid at the checkout.
