Why Small Business Matters More as Iran Drives Costs Higher

The Iran conflict is already pushing costs higher across the U.S. economy. Rising oil prices are increasing fuel, transportation, and logistics expenses, and those increases are moving quickly through supply chains. For businesses, this is not a distant geopolitical development; it is a direct increase in operating costs that compresses margins and forces more cautious decision-making.

Small businesses are where the economy grows

This is how inflationary pressure re-emerges – not from excess demand, but from rising input costs. As energy and transportation expenses increase, manufacturers pay more to move goods, distributors absorb higher delivery costs, and service providers face tighter margins. The immediate risk is not simply higher prices, but slower economic activity as businesses delay hiring and investment in response to rising costs and uncertainty.

But the Iran shock does not determine the outcome. The trajectory of the economy will be determined by whether businesses can continue to expand in the face of those pressures and whether policy allows them to do so. That answer runs directly through small business.

Small businesses are the mechanism through which growth occurs in the United States. They employ nearly half of the workforce and generate the majority of net new jobs. When they expand, hiring rises, supply chains activate, and economic momentum builds. When they hesitate, those same channels slow, and growth weakens regardless of broader macroeconomic conditions.

Today, small businesses are not pulling back, but they are moving more cautiously. Higher fuel and transportation costs are compressing margins, borrowing costs remain elevated for many firms, and the process of expansion continues to be slowed by regulatory complexity, permitting timelines, and compliance requirements. The result is not contraction, but hesitation. And hesitation is what slows economies.

The Trump administration understands

To its credit, the Trump administration has moved policy in a more pro-growth direction. Pro-investment tax policy has been strengthened, and early efforts to streamline regulatory processes reflect a recognition that compliance burdens and administrative delays have become real constraints on expansion.

At the same time, the “One Big Beautiful Bill” has provided long-sought certainty around pro-investment tax policy, particularly through full expensing, materially improving the economics of capital investment for small businesses. That is a meaningful step forward. But it does not solve the central problem. If businesses cannot move from decision to execution quickly and predictably, even well-structured investments will be delayed.

A business considering expansion today is not simply responding to demand; it is navigating a system where permitting delays, layered compliance requirements, and execution risk extend timelines and increase costs. Even when the economics of a project are sound, the path to implementation can slow hiring and investment decisions.

When this pattern plays out across millions of firms, the result is an economy that continues to grow, but at a slower pace than its underlying fundamentals would otherwise support. This is not a demand problem. It is a systems problem.

The transmission mechanism of growth

In “Rethinking Economic Growth,” I argue that small businesses are the transmission mechanism of economic growth. Growth is not driven from the top down; it is built through the cumulative decisions of businesses choosing to invest, hire, and expand. That process depends on speed, clarity, and confidence in the operating environment.

That is where policy must now focus. If the goal is to offset the economic impact of rising costs and sustain growth, the most effective approach is not broad stimulus, but targeted reduction of the barriers that slow small business expansion. Accelerating permitting timelines, simplifying compliance requirements, and providing greater regulatory clarity would directly reduce the cost and uncertainty associated with investment decisions.

When those conditions are in place, small businesses respond quickly. Hiring increases, supply chains adjust, and economic growth strengthens. When they are not, the economy continues to expand, but below its potential.

The Iran conflict is a test, but not simply of economic resilience. It is a test of whether the policy environment allows small businesses to act as the engine of growth. If it does, they will absorb rising costs and continue expanding. If it does not, the effects of higher costs will extend beyond prices and into the pace of economic activity itself.
