Issued initially in July 1988 by the Basel Committee on Banking Supervision, the Basel Capital Adequacy Accord is a risk based capital adequacy methodology that defines the components of capital and applies a series of risk weights and capital charges to banks' assets and holdings of financial instruments. The Accord aims to increase the stability of the international financial system through having a single internationally acknowledged measurement of a bank's capital expressed as a percentage of its financial risks. It also serves to put internationally active banks on an equal competitive footing in respect of the measurement of their capital adequacy.
