An oil embargo is an economic situation wherein entities engage in an embargo to limit the transport of petroleum to or from an area, in order to exact some desired outcome. One commentator states, "[a]n oil embargo is not a common commercial practice; it is a tool of political blackmail, meant to force those at whom it is aimed, into some action they would otherwise not be willing to take".
