The U.S. President imposes freeze on Iran property in U.S.

The White House moved to enforce tightened sanctions against Iran February 6 because of the country’s suspect nuclear program, freezing all property of the Central Bank of Iran, other Iranian financial institutions, and the Iranian government in the United States.

The new restrictions also raised new warnings to financial institutions in other nations that they could face big penalties in the United States if they did business with Iran’s central bank.

The actions were announced in an executive order signed by the U.S. President that started the enforcement process for a tough measure he signed into law at the end of 2011.

 In a statement, the White House said the executive order "re-emphasizes this administration’s message to the government of Iran — it will face ever-increasing economic and diplomatic pressure until it addresses the international community’s...concerns regarding the nature of its nuclear program."

Many countries buy oil from Iran through its central bank, and their financial institutions could be blocked from the American market if they continue to do so. Documents accompanying the executive order said foreign financial institutions risked American sanctions "if they engage in certain significant financial transactions" with Iran’s central bank rather than "arms-length" transactions. In a statement, the Treasury Department said the executive order "blocks all property and interests in property of the government of Iran, the Central Bank of Iran and all Iranian financial institutions (regardless of whether the financial institution is part of the government of Iran) that are in the United States, that come within the United States or that come within the possession or control of U.S. persons." The statement did not further specify the exact properties that apply.
