“knowing” and “significant” financial activity, which is defined ad hoc by the State Department
and OFAC.
There are four main categorizations of OFAC sanctions in terms of scope. First, there are
comprehensive sanctions. These sanctions target entire countries or regions, such as the U.S.
sanctions on Cuba, and almost entirely block the country from economic ties with the U.S. (with
the exception of some humanitarian carve outs).
Second, and less extreme, are regime-based sanctions. These sanctions, also referred to as
list-based sanctions, include those against Iran that targeted Iran’s government, military, and
associated SOEs.
Third, are sectoral sanctions, such as those that were placed on Venezuela in 2019
targeting their oil and gas (O&G) sector.
From 2014 to 2022, U.S. sanctions on Russia could
have been considered regime-based or sectoral, as they targeted specific oligarchs and companies
complicit in the annexation of Crimea limited to certain sectors, like defense and O&G.
However, the sanctions imposed on Russia in response to their February 2022 invasion of
Ukraine were comprehensive. While they are not as stringent as the sanctions on countries like
Cuba and North Korea, for an economy of Russia’s size and global presence, they are about as
harsh as could feasibly be imagined. This is especially true considering that, unlike in the case of
Cuba, the U.S. was joined in its efforts by the EU and the UK.
Finally, the fourth type of sanctions are Global Magnitsky sanctions that target specific
individuals, usually for human rights violations.
Sanctioned persons and entities are maintained by OFAC on the SDN list. Any entity that
has fifty percent or more aggregate beneficial ownership by individuals or entities on the SDN
