Banking and insurance in Iran

Following the Iranian Revolution, Iran's banking system was transformed to be run on an Islamic interest-free basis. As of 2010 there were seven large government-run commercial banks. As of March 2014, Iran's banking assets made up over a third of the estimated total of Islamic banking assets globally. They totaled 17,344 trillion rials, or US$523 billion at the free market exchange rate, using central bank data, according to Reuters.

Since 2001 the Iranian Government has moved toward liberalising the banking sector, although progress has been slow. In 1994 Bank Markazi (the central bank) authorised the creation of private credit institutions, and in 1998 authorised foreign banks (many of whom had already established representative offices in Tehran) to offer full banking services in Iran's free-trade zones. The central bank sought to follow this with the recapitalisation and partial privatisation of the existing commercial banks, seeking to liberalise the sector and encourage the development of a more competitive and efficient industry. State-owned banks are considered by many to be poorly functioning as financial intermediaries. Extensive regulations are in place, including controls on rates of return and subsidized credit for specific regions. The banking sector in Iran is viewed as a potential hedge against the removal of subsidies, as the plan is not expected to have any direct impact on banks.

As of 2008, demand for investment banking services was limited. The economy remains dominated by the state; mergers and acquisitions are infrequent and tend to take place between state players, which do not require advice of an international standard. The capital markets are at an early stage of development. "Privatization" through the bourse has tended to involve the sale of state-owned enterprises to other state actors. There is also a lack of sizeable independent private companies that could benefit from using the bourse to raise capital. As of 2009, there was no sizeable corporate bond market. In 2024 the banking sector underwent a cyberattack, the "worst attack" in Iranian history by hackers, forcing the Iranian government to pay ransom to release the data of Iranian customers.

In 1960 the Central Bank of Iran (CBI, also known as Bank Markazi) was established as a banker for the government, with responsibility for issuing currency. In 1972 legislation further defined the CBI's functions as a central bank responsible for national monetary policy. In the 1960s and 1970s, the expansion of economic activity fueled by oil revenues increased Iran's financial resources, and subsequently the demand for banking services increased exponentially. By 1977, some 36 banks (24 commercial and 12 specialized) with 8,275 branches were in operation. Their topline revenue has always been trade finance and letters of credit.

After the Revolution, the government nationalized domestic private banks and insurance companies. Bank law was changed under new interest-free Islamic banking regulations. The post-Revolution reduction in economic activity and financial resources required banks to consolidate. By 1982, this consolidation, in conformity with the Banking Nationalization Act, had reduced the number of banks to nine (six commercial and three specialized) and the number of branches to 6,581. Subsequently, the system expanded gradually.

The government began to privatize the banking sector in 2001 when licenses were issued to two new privately owned banks.

In 2014, Iranian authorities arrested 12 people for embezzlement of more than $4.5 billion (3.6 billion euros) from the Kerman branch of Tejarat Bank from 2009 until their arrest in 2013.

In 2024 the banking sector underwent the "worst attack" in Iranian history by hackers according to Politico, forcing the Iranian government to pay ransom to release the data of Iranian customers. The Iranian government hid the attack from citizens, fearing a bank run and the collapse of an unstable Iranian financial sector.
