Industry Ministry data show that small and medium-sized enterprises borrowed about 200 trillion rials ($750 million) in 11 months to Feb.19.
The official state news agency, IRNA, said the money was given to 4,881 applicants.
Companies employing 50 workers or less, and 100 workers or less are considered small- and medium-sized enterprises. According to the Iran Small Industries and Industrial Parks Organization, Iran is home to 80,000 registered SMEs.
As per Central Bank of Iran rules, lending priority must be given to SMEs introduced by special provincial task forces provided that they are financially and technically viable and ensure sustainable employment.
The next priority is given to SMEs whose output is marketable and highly-demanded with low potential of accumulation in warehouses.
Firms with downed shutters or operating at half capacity are third on the eligibility list for loans and the lender must first determine that that condition is due to a credit crunch.
Banks can also give loans to businesses that have remained dormant for years and can be revived with fresh injections of cash.
Loans can also go to enterprises that are creditors of state and executive organizations and companies and the government has failed to pay them.
SMEs play an important role in the Iranian economy. They outnumber large firms, employ more people and are generally entrepreneurial and innovative. Reports say SMEs constitute 92% of the 85,000 manufacturing enterprises.
Many people in emerging economies find work in small- and medium-sized enterprises. SMEs contribute roughly 45% of total employment and 33% of GDP in such countries, according to the Organization for Economic Cooperation and Development.
