Iran’s financial landscape is heavily influenced by its political structure and international relations. Dominated by state-owned banks, the system operates under strict Islamic finance principles (Sharia law), which prohibit interest-based lending (riba) and excessive speculation (gharar). The banking sector, crucial for economic activity, faces significant challenges. International sanctions, particularly those imposed by the United States, severely restrict access to the global financial system. Iranian banks are largely cut off from SWIFT, hindering international transactions and investment. This has led to the development of alternative payment systems, but these are often less efficient and face compliance hurdles. The Tehran Stock Exchange (TSE) is the primary Iranian stock market. While it has experienced periods of growth, fueled by domestic liquidity and limited investment options, it is prone to volatility due to geopolitical risks and policy uncertainty. Foreign investment remains limited due to the complex regulatory environment and sanctions. Inflation is a persistent problem, often exacerbated by currency devaluation and government spending. The Iranian Rial (IRR) has seen significant depreciation against major currencies, impacting purchasing power and increasing the cost of imports. The government implements various measures to control inflation, including price controls and currency exchange policies, but their effectiveness has been limited. The informal economy plays a substantial role, operating largely outside formal regulations and tax structures. This sector provides a vital source of income for many Iranians, but its lack of transparency poses challenges for economic management and data collection. Access to finance, especially for small and medium-sized enterprises (SMEs), remains a major constraint. State-owned banks often prioritize lending to politically connected entities, hindering access for smaller businesses. Microfinance institutions exist, but their reach is limited. The future of Iran’s financial system is intrinsically linked to its political trajectory and international relations. Easing of sanctions could unlock significant economic potential, facilitating access to international capital and trade. However, even with sanctions relief, structural reforms are needed to improve transparency, strengthen the banking sector, and promote a more competitive business environment. Without such reforms, Iran’s financial system will likely continue to struggle with inefficiency, instability, and limited integration with the global economy. The development of robust digital financial infrastructure and greater private sector participation could also play a crucial role in modernizing the system.
