In the current SNA international organizations are part of the rest of the world. Paragraph 4.165 specifies that: For purposes of the System, international organizations are treated as units that are resident in the rest of the world. The SNA does not distinguish international organizations separately and gives very little or no guidance on the concrete treatment of the transactions between the international organizations and the national economies.
Unlike the SNA, the European system of accounts contains an additional classification of the rest of the world sector. Paragraph 2.92 specifies the European Union institutions as a separate sub-sector of the rest of the world.
