Member Country

A Member Country is a nation that has formally joined a Multilateral Development Bank by subscribing to a share of the bank's capital stock and ratifying its founding charter, gaining both governance rights and procurement eligibility under the bank's financed projects.

What is a Member Country?

MDBs are owned by their member countries, which hold shares proportional to their capital subscriptions. Membership confers several rights: voting power on bank governance decisions, eligibility to borrow (for qualifying members), and most importantly for suppliers, eligibility for nationals and firms to participate in procurement financed by that bank. Most major MDBs restrict contract awards to firms and individuals from member countries, so a company's nationality relative to the lending MDB's membership list is a threshold eligibility question before any bid preparation begins.

Member countries fall into two broad categories: borrowing-country members, which receive loans and grants and are typically developing economies, and non-borrowing-member-country members, which contribute capital and have voting influence but do not borrow from the bank. Both categories of member country nationals are generally eligible to bid on financed procurement, though rules vary by institution and some MDBs are more open than others.

Why Member Country matters for bidders

Membership eligibility is the first filter a supplier applies when evaluating whether it can bid on a given MDB contract. A firm incorporated in a non-member country is generally ineligible regardless of its technical qualifications. The eligibility check is straightforward: confirm the supplier's country of incorporation (or the country of the majority owner in a joint venture) is on the MDB's current member list. Lists are publicly available on each MDB's website. For joint ventures that include firms from both member and non-member countries, the rules on permissible structures vary by institution, so the specific procurement framework governs.

FAQ

How many countries are members of the World Bank?

The World Bank Group has 189 member countries, making it the most broadly based MDB. Other institutions have smaller membership: the ADB has 69 members, the AfDB has 81 (54 regional and 27 non-regional), and the AIIB has grown to over 109 members.

Can a country be a member of multiple MDBs?

Yes. Most large economies hold membership across several MDBs simultaneously. A firm in France, for example, is typically eligible for World Bank, ADB, AfDB, AIIB, IDB, EIB, EBRD, and other MDB procurement, each subject to that bank's specific eligibility rules.

Does membership change the procurement rules that apply?

Membership determines eligibility to participate, but the procurement rules themselves are set by the MDB's framework for each project type. Eligibility and procurement method are separate considerations: a firm from a member country still must comply with all applicable rules in the solicitation.
