Overview
The Office of Foreign Assets Control (OFAC) is a financial intelligence and enforcement agency of the United States Treasury Department. It administers and enforces economic and trade sanctions in support of U.S. national security and foreign policy objectives. Under presidential national emergency powers, OFAC carries out its activities against foreign governments, organizations (including terrorist groups and drug cartels), and individuals deemed a threat to U.S. national security.
Founded in 1950 as the Division of Foreign Assets Control, since 2004 OFAC has operated under the Office of Terrorism and Financial Intelligence within the Treasury Department. It is primarily composed of intelligence targeters and lawyers. While many of OFAC's targets are broadly set by the White House, most individual cases are developed as a result of investigations by OFAC's Office of Global Targeting (OGT).
Sometimes described as one of the "most powerful yet unknown" government agencies, OFAC has the power to levy significant penalties against entities that defy its directives, including imposing fines, freezing assets, and barring parties from operating in the U.S.

History
Involvement of the U.S. Department of the Treasury in economic sanctions against foreign states dates to the War of 1812, when Secretary Albert Gallatin administered sanctions against the United Kingdom in retaliation for the impressment of American sailors.
Predecessor agencies of the Division of Foreign Assets Control include Foreign Funds Control (FFC), which existed from 1940 to 1947, and the Office of International Finance (1947 to 1950). FFC was established by Executive Order 8389 as a unit of the Office of the Secretary of the Treasury on April 10, 1940. The authority to establish FFC was derived from the Trading with the Enemy Act 1917. Among other operations, FFC administered wartime import controls over enemy assets and restrictions on trade with enemy states.
It also participated in administering the "Proclaimed List of Certain Blocked Nationals", or the "Black List", and took censuses of foreign-owned assets in the US and American-owned assets abroad. FFC was abolished in 1947, with its functions transferred to the newly established Office of International Finance (OIF). In 1948, OIF activities relating to blocked foreign funds were transferred to the Office of Alien Property, an agency within the Department of Justice.
The Division of Foreign Assets Control, OFAC's immediate predecessor, was established in the Office of International Finance by a Treasury Department order in December 1950, following the entry of the People's Republic of China into the Korean War; President Harry S. Truman declared a national emergency and tasked the Division with blocking all Chinese and North Korean assets subject to U.S. jurisdiction. The Division also administered regulations and orders issued under the amended Trading with the Enemy Act.
On October 15, 1962, by a Treasury Department order, the Division of Foreign Assets Control became the Office of Foreign Assets Control.

Authority and activities
In addition to the Trading with the Enemy Act and the various national emergencies currently in effect, OFAC derives its authority from a variety of U.S. federal laws, particularly the International Emergency Economic Powers Act (IEEPA), regarding embargoes and economic sanctions.
In enforcing economic sanctions, OFAC acts to prevent "prohibited transactions", which are described by OFAC as "trade or financial transactions and other dealings in which U.S. persons may not engage unless authorized by OFAC or expressly exempted by statute". OFAC has the authority to grant exemptions to prohibitions on such transactions, either by issuing a general license for certain categories of transactions, or by specific licenses issued on a case-by-case basis.
Under the International Emergency Economic Powers Act (IEEPA), the U.S. president can block the removal of foreign assets under U.S. jurisdiction during national emergencies. OFAC executes this mandate by issuing regulations to financial institutions.

Specially Designated Nationals
OFAC publishes a list of Specially Designated Nationals (SDNs), which lists people, organizations, and vessels with whom U.S. citizens and permanent residents are prohibited from doing business. This list differs from the list maintained pursuant to Section 314(a) of the Patriot Act.
In August 2009, a federal court ruling in KindHearts v. Treasury found that Treasury's seizure of KindHearts assets without notice or means of appeal was a violation of the Fourth and Fifth Amendments to the Constitution.
On September 23, 2011, the Ninth Circuit Court of Appeals upheld a lower court's ruling that procedures used by the Treasury to shut down the Oregon-based Al Haramain Islamic Foundation in 2004 were unconstitutional. The court said the Fifth Amendment's guarantee of due process required the Treasury to give adequate notice of the reasons it puts a group on the terrorist list, as well as a meaningful opportunity to respond. In addition, the court ruled that freezing the group's assets amounts to a seizure under the Fourth Amendment, so that a court order is required.

Sectoral Sanctions Identifications
OFAC publishes a list of Sectoral Sanctions Identifications (SSI), which lists persons, companies, and entities in sectors of the Russian economy (especially energy, finance, and armaments), prohibiting certain types of activity with these individuals or entities by US persons, wherever located. This list is maintained following the issuance of EO 13662 Blocking Property of Additional Persons Contributing to the Situation in Ukraine on March 20, 2014, in accordance with 79 FR 16167.
On August 13, 2014, the Treasury Department issued guidance for entities under sectoral sanctions. It increased the number of entities on the sectoral sanctions identifications list by adding subsidiaries of entities under sectoral sanctions that hold 50% or greater ownership by an entity under sectoral sanctions either individually or in the aggregate, either directly or indirectly.
Further, US persons cannot use a third party intermediary and must exercise caution during "transactions with a non-blocked entity in which one or more blocked persons has a significant ownership interest that is less than 50% or which one or more blocked persons may control by means other than a majority ownership interest."
On December 22, 2015, the Treasury Department explicitly listed all entities and their subsidiaries on the sectoral sanctions identifications list using a human readable search.
