Minimum capital is a concept used in corporate law and banking regulation to stipulate what assets the organisation must hold as a minimum requirement.
The purpose of minimum capital in corporate law is to ensure that in the event of insolvency or financial instability, the corporation has a sufficient equity base to satisfy the claims of creditors.
In banking and financial regulation it is normally referred to as the capital requirement.
[1] All public companies within the European Union are required to hold at least €25,000 in capital, although many countries go above this minimum requirement.
[2][3] The requirement is e.g. £50,000 in the United Kingdoms (England and Wales), of which at least 25% must be paid up (of the nominal amount and of any premium).
