Tariffs Squeeze Small Businesses as Iran Conflict Drives Oil Prices and Shipping Costs Higher

Rising oil prices and shipping disruptions caused by the ongoing Iran conflict are adding to the financial pressures already faced by small businesses. With global crude prices reaching multi-year highs, the cost of operating and transporting goods has spiked, creating new hurdles for businesses with limited margins. Analysts warn that the war could further disrupt trade flows and supply chains in the coming weeks.

Small business owners have struggled with tariffs imposed by the Trump administration on imports from China, Canada, and the European Union. These tariffs have increased input costs and squeezed profit margins, leaving smaller firms vulnerable to additional shocks. Unlike larger corporations, small businesses often lack the financial reserves to absorb sudden cost increases or logistical setbacks.

Spain has taken steps to alleviate the economic effects of the war by announcing a €5 billion aid package. The measures include tax cuts on energy and sales of electricity, aiming to reduce the burden on households and businesses. Prime Minister Pedro Sánchez said the package will help buffer the country from rising fuel prices and global market volatility.

Why the Conflict Is Impacting Smaller Firms

The Iran war has led to a sharp rise in air freight costs, with some routes experiencing an 82% increase in prices. The closure of key Gulf airports and rising jet fuel costs are straining the global air freight network, especially for industries like pharmaceuticals and electronics. According to reports, freight costs have surged dramatically.

Small businesses, however, are facing even greater pressure. With limited purchasing power and supply chain flexibility, they are more exposed to delays and increased shipping costs. Analysts say the worst may still be ahead, as small businesses have only a few months of operating reserves before they must confront renewed contracts or higher expenses.

How Other Industries Are Responding to the Crises

U.S. airlines, including Delta and American, have offset rising fuel costs through strong demand in leisure and corporate travel. These carriers have raised first-quarter revenue forecasts, demonstrating resilience despite an additional $400 million in fuel-related expenses.

In contrast, European airlines are challenging the EU's synthetic aviation fuel (eSAF) mandate, arguing that supply shortages make compliance unfeasible. Airlines for Europe warns that the requirement could result in costly penalties and higher passenger fares, urging a delay or revision of the mandate.

The S&P 500 fell 1.6% during the second week of March as investors reacted to rising oil prices. The decline highlights growing concerns about inflationary pressures and their potential impact on economic growth.

What Analysts Are Watching Next

Analysts like David Woo believe U.S. ground forces could be deployed in Iran within a week if airstrikes fail to resolve the standoff at the Strait of Hormuz. A ground operation, while politically contentious, could escalate the conflict and further disrupt global oil markets.

Spain's ability to manage its energy costs through increased natural gas imports and renewable energy may offer a model for other countries. Prime Minister Sánchez said the nation's reliance on renewables has helped shield it from the worst of the crisis.

Investors are closely monitoring how small businesses navigate these challenges. With limited margins and dwindling reserves, any further disruptions could force difficult decisions, including layoffs or price hikes, that could ripple through local economies. As analysis shows, small businesses face significant vulnerabilities in times of crisis.
