How U.S. trade uncertainty is buffeting small business
Small businesses make up about a third of U.S. international trade and employ almost 46% of American workers. Even though they play a key role in the economy, new research from Harvard Business School shows that many small and medium sized companies are struggling to survive as U.S. trade policy becomes more unpredictable.
A survey of over 4,000 small and medium-sized businesses found that quick changes in tariffs, being announced, delayed, withdrawn, and brought back, make it almost impossible for owners to predict costs, set prices, or sign long-term supplier contracts. Researchers say this uncertainty acts like a tax, making businesses delay hiring, put off investments, or rethink expanding.
Small businesses usually don’t have the cash reserves, legal help, or flexible supply chains that big companies do to handle sudden policy changes. Many depend on imported materials and can’t easily switch to domestic options, which are often more costly or hard to find. As a result, trade volatility hits smaller firms harder.
What stands out to me is not just the tariffs themselves, but how unstable they are. Even businesses willing to pay more can’t operate effectively when the rules keep changing. Economic policy does not happen in isolation; consistency is just as important as intent.
This uncertainty also gives bigger companies more power. Businesses with lawyers, consultants, and global supply chain experts can adapt more easily, while smaller firms are left to react rather than plan. Over time, this creates an uneven playing field that helps large corporations and makes it harder for small businesses to compete.
The effects go beyond just financial numbers. Small businesses are closely connected to their communities as employers, service providers, and sources of local stability. When they cut back or close, it leads to job losses, reduced access to goods and services, and fewer opportunities for people to move up economically.
Whether you support or oppose tariffs, the research shows one clear point: a predictable trade policy is important. Without a stable, clear system, uncertainty stunts growth and survival, especially for small businesses, the backbone of the U.S. economy.
