The current conflict between the United States and Iran is not only military—it has become a global economic shock.

Small businesses worldwide are among the most affected, often more than large corporations.

Why small businesses are hit hardest

Small businesses have:

•    Low savings

•    Small profit margins

•    Weak supply chains. So sudden global shocks affect them quickly.

Experts say geopolitical risk is now a core business risk for all companies, especially smaller ones. (Coleman Management Advisors)

1) Oil & fuel shock → biggest problem for small business

The war has disrupted the Strait of Hormuz, where ~20% of global oil passes daily. (Coleman Management Advisors)

This caused:

•    Huge oil price volatility

•    Fuel price increases worldwide

•    Shipping cost surges

Effects on small businesses:

•    Transport cost ↑

•    Electricity cost ↑

•    Raw material cost ↑

Even in the US:

•    Gas, flights, food and shipping prices are rising. (The Washington Post)

👉 Small businesses cannot hedge oil prices like big corporations, so profits fall quickly. (Coleman Management Advisors)

 

🚢 2) Shipping crisis & supply chain chaos

Ships are avoiding the war zone and rerouting around Africa.

This causes:

•    Delivery delays of weeks

•    Shipping cost increase 15–25% (Coleman Management Advisors)

•    Freight prices up to 10× in some sectors (The Economic Times)

Small business impact:

•    Late inventory

•    Out-of-stock products

•    Lost customers

•    Production shutdown risk

Industries most affected:

•    E-commerce

•    Manufacturing

•    Agriculture

•    Retail

3) Raw material prices exploding

Petrochemical and plastic prices jumped 60%. (The Economic Times)

Why this matters: Plastic is used in:

•    Packaging

•    Food containers

•    Electronics

•    Clothing

•    Construction

Result: Small factories & exporters are losing competitiveness.

4) Inflation → customers buy less

War → higher fuel + shipping → higher product prices → inflation.

Experts warn the war could cause:

•    Higher inflation

•    Slower global growth (The Guardian)

Small businesses suffer because:

•    Customers reduce spending

•    Demand falls

•    Sales drop

This is already happening in Iran’s bazaars where shops reopened but sales remain slow. (Al Jazeera)

🇺🇸 Impact on small businesses in the USA

US small businesses face:

Cost increases

•    Fuel

•    Shipping surcharges

•    Packaging

•    Ingredients

•    Import goods

The U.S. Postal Service even added an 8% package fee due to fuel costs. (The Washington Post)

Profit squeeze

Small businesses must choose:

•    Raise prices → lose customers

OR

•    Keep prices → lose profit

This is the biggest crisis for US small business owners right now.

Impact on small businesses in Iran

Iran is facing much worse conditions:

•    War damage

•    Sanctions

•    Currency weakness

•    Banking restrictions

•    Low consumer spending

The economic outlook is described as grim despite ceasefire attempts. (Al Jazeera)

Small Iranian businesses face:

•    Lack of imports

•    Payment problems

•    Falling sales

•    Unemployment risk

Global winner’s vs losers

Biggest losers

Small businesses in:

•    Retail

•    Food & restaurants

•    Manufacturing

•    Import/export

•    Logistics

•    Travel

Some winners

Some small businesses benefit:

•    Local producers (less imports)

•    Repair services

•    Energy & solar installers

•    Security & defense suppliers

War shifts demand.

The big global picture

Economists warn the war could create a “geoeconomic firestorm.” (Council on Foreign Relations)

Main long-term risks:

•    Persistent inflation

•    Slower growth

•    More trade barriers

•    More geopolitical conflict

This means the world economy becomes:

👉 More expensive

👉 More unstable

👉 Harder for small businesses

 

Simple summary

If the USA–Iran war continues:

Small businesses worldwide will face:

1.  Higher costs

2.  Supply delays

3.  Lower customer spending

4.  More uncertainty

Large companies struggle too — but small businesses feel the pain first and strongest.
