From freezing the assets of senior regime figures to an arms embargo or banning the export of carpets, Iran faces a long list of sanctions aimed at isolating it from the international arena.
Since May 2018, when the United States withdrew from the nuclear deal signed with Iran, Washington has imposed unprecedented punitive measures against Tehran.
Pending additional measures announced by US President Donald Trump, on Wednesday, below is a list of the various sanctions currently targeting Iran.
Also included in the US goals are Foreign Minister Mohammad Jawad Zarif, the main interlocutor of the Europeans, China and Russia.
Since August 1, his assets in the United States have been frozen, financial exchanges with him blocked, and Washington has made his moves difficult.
Eight senior Iranian Revolutionary Guards officials, who in turn were listed as a system on the US blacklist of “foreign terrorist organizations”, as well as its Qods Force, were also punished.
Drying of oil exports
Crude and light oil are vital to the Iranian economy. Since May, exceptions granted to eight countries, including Turkey and India, for the purchase of Iranian oil have been canceled, in a further step to dry up the Islamic Republic's exports.
The result, according to the Kepler office, oil products moved from two million barrels per day at the beginning of 2018 to 400,000 barrels in July.
The petrochemical sector was also targeted after Washington imposed sanctions on the Persian Gulf Petrochemical Industries Company, a large group linked to the Iranian Revolutionary Guards, which accounts for 40% of Iran's petrochemical production capacity and 50% of its exports.
Washington considers this group to provide financial support to the "Seal of Prophets" of the Revolutionary Guards and is active locally in the majority of large infrastructure projects.
In August 2018, Washington barred the Iranian government from buying the dollar, creating significant difficulties for residents and businesses to obtain the dollar.
Transactions between foreign financial institutions, the Central Bank of Iran and all Iranian banks were also banned. These banks no longer have access to the global financial system.
The Trump administration is also seeking to prevent Iranian banks from using the global banking network (SWIFT) through which all transfers in the world pass.
In April, Washington imposed sanctions on Unicredit and Standard Chartered for violating the sanctions, worth more than $ 1 billion each.
Washington also banned the exchange of gold and precious metals with Iran.
Flight of foreign companies
With sanctions targeting the iron, steel, aluminum, copper and coal sectors, it has become difficult for foreign companies to maintain business in Iran.
The auto industry, which benefited from a period of openness with the lifting of sanctions following the conclusion of the nuclear deal, was imposed on it, and the majority of European car manufacturers abandoned their investments in Iran.
Iran has ordered 100 Airbus and 80 Boeing aircraft to upgrade its aging fleet. However, following the sanctions, the plan became void.
Sanctions were also imposed on shipbuilding and maritime transport. Cooperation agreements between Iran and the Fincantiari group were also signed in 2016.
Groups such as General Electric and Total have also announced their exit from the Iranian market.
UN and EU sanctions
Between 2006 and 2010, the United Nations passed four resolutions: 1737, 1747, 1803, and 1929, including economic and trade sanctions against entities related to Iran's nuclear program, and a ban on the purchase of Iranian weapons.
In January 2016, after the nuclear agreement was reached, resolution 2231 allowed for a gradual and partial lifting of these sanctions within 10 years.
For example, the UN ban on conventional weapons and ballistic missiles continues by virtue of the resolution until 2020 and 2023.
The EU is trying to help Iran through the Instex mechanism aimed at avoiding the use of the dollar.
The International Atomic Energy Agency (IAEA) has the responsibility to monitor Iran's nuclear sites under much expanded powers.
