In 2022, India, Brazil, Germany, and Japan (the G4) renewed their push for UN Security Council reform, arguing that the institutional power embedded in the P5 veto no longer reflects contemporary geopolitical realities.

Institutional power is one of four forms of power identified in Michael Barnett and Raymond Duvall's influential 2005 International Organization article "Power in International Politics," alongside compulsory, structural, and productive power. It refers to the ability of actors to control others at a distance through the mediating rules and procedures of institutions, rather than through direct coercion.

The concept emphasizes that institutions are not neutral arenas. Their voting rules, agenda-setting prerogatives, membership criteria, and procedural defaults systematically advantage some actors and disadvantage others, often long after the original bargain that created them. Crucially, the actors exercising institutional power need not be present or active in any given decision; the rules do the work.

Classic illustrations include:

UN Security Council veto: The five permanent members (P5) can block substantive resolutions, giving them durable leverage over outcomes they may not even need to negotiate.
Weighted voting at the IMF and World Bank: Quota shares tied to economic weight give the United States and other large economies disproportionate influence over lending conditions and policy.
Consensus rules at the WTO: Procedurally egalitarian, but in practice they have allowed powerful trading blocs to shape agendas in informal "green room" meetings.
Agenda-setting in the European Council and Commission: Control over what reaches a vote is itself a form of power.

Institutional power is indirect and diffuse: actor A shapes the circumstances facing actor B through rules A helped design, even without bilateral interaction. It overlaps with what Steven Lukes called the "second face" of power (agenda control) and with historical-institutionalist arguments about path dependence. Critics note that the category can blur into structural power when rules become deeply constitutive of actor identities. For MUN delegates and IR researchers, the concept is useful for explaining why reform of bodies like the UNSC or IMF is so contested: changing the rules redistributes power without firing a shot.

Frequently asked questions

Who developed the concept of institutional power?

Michael Barnett and Raymond Duvall articulated it as part of a four-part taxonomy of power in their 2005 article 'Power in International Politics' in the journal International Organization.

How does institutional power differ from compulsory power?

Compulsory power involves direct, often coercive control of one actor over another (e.g., sanctions or force). Institutional power works indirectly through rules and procedures, and the powerful actor need not be actively engaged in a given decision.

Why is institutional power relevant to UN reform debates?

Because rules like the P5 veto or weighted IMF quotas lock in advantages from earlier eras. Reforming them is contentious precisely because procedural change reallocates influence across states.
