Economies are not only damaged by crises themselves; they are often weakened even more by prolonged uncertainty. A war can destroy infrastructure, disrupt trade and increase costs, but it usually has a clear beginning and an end. Peace, meanwhile, provides a foundation for planning and investment. The most difficult situation for an economy is the space between these two conditions: neither war nor peace.
This situation creates a hidden burden that economists call the “tax of uncertainty.” It is not a tax imposed by the government, but a cost paid by businesses, investors and households. In Iran, this cost has become increasingly visible as economic decisions are influenced not only by market conditions, but also by expectations about political and security developments.
When the future is difficult to predict, companies become more cautious. Investment plans are delayed, expansion projects are postponed and financial resources move away from productive activities toward safer and more liquid assets. Instead of calculating potential profits, businesses focus on managing risks. Over time, this behavior reduces investment, weakens productivity and lowers the economy’s growth potential.
One of the main consequences of uncertainty is the rise in perceived risk. Investors need confidence that economic rules will remain stable and that future conditions can be reasonably predicted. When sudden changes appear possible, the required return on investment increases. As a result, even profitable projects may become unattractive because the risks are considered too high.
Uncertainty also increases the cost of financing. Banks, investors and lenders demand higher returns when they face greater risks. This creates additional pressure on companies, especially manufacturing firms that require long-term capital. Higher financing costs can limit production capacity, slow technological development and reduce economic competitiveness.
The foreign exchange market is another area affected by uncertainty. In economies facing external restrictions and inflationary pressures, political uncertainty often increases demand for foreign currencies and other safe assets. Even when monetary authorities use their tools to control volatility, maintaining stability becomes more expensive. Instead of focusing entirely on long-term economic goals, policymakers must spend more resources managing short-term shocks.
Household behavior also changes in uncertain environments. Families may postpone purchases of durable goods because they are unsure about future income and prices. Others may increase precautionary purchases if they expect higher inflation. Both reactions can disrupt market balance and reduce the flow of resources toward productive investment.
The government also faces additional pressure. In a prolonged period of uncertainty, it must maintain security-related spending while also supporting the economy against external shocks. If this situation continues, fiscal pressures may increase and managing budget deficits may become more difficult. This makes fiscal discipline and avoiding inflationary financing methods even more important.
However, the economic costs of uncertainty are not determined only by external conditions. Domestic policies also play a crucial role. Clear regulations, transparent economic decisions, stronger institutions and a stable business environment can help reduce the impact of political risks.
Central Priority
For Iran, rebuilding confidence should become a central economic priority. Businesses need to know that monetary, fiscal and exchange-rate policies are based on clear rules rather than temporary reactions. Greater transparency, better communication and fewer sudden policy changes can reduce the uncertainty premium paid by the economy.
Iran’s economy has shown resilience in facing major shocks over the past decades. Yet prolonged ambiguity can gradually weaken economic capacity by discouraging investment and delaying decisions. Growth does not suffer only because resources are unavailable; it suffers because uncertainty prevents those resources from being used effectively.
Political developments may not always be under the control of economic policymakers. However, reducing domestic uncertainty, strengthening macroeconomic stability, protecting property rights and improving the investment environment remain essential tasks. In uncertain times, economies need clear rules more than ever. The lower the cost of uncertainty, the greater the chance for investment, production and sustainable growth.
