The United Nations classifies Iran's economy as semi-developed. In 2014, Iran ranked 83rd in the World Economic Forum's analysis of the global competitiveness of 144 countries. Political, policy and currency stability are regarded as the most problematic factors in doing business in Iran. Difficulty in accessing financing is also a major concern, especially for small and medium enterprises. Most of Iran's financial resources are directed at trading, smuggling and speculation instead of production and manufacturing. According to Goldman Sachs, Iran has the potential to become one of the world's largest economies in the 21st century. Iranian President Hassan Rouhani stated, in 2014, that the country has the potential to become one of the ten largest economies within the next 30 years.
