The capital adequacy standard according to Basel III is considered one of the
most prominent tools for hedging risks, and it is imposed by all central banks. However, Islamic
banks find some difficulties to apply this standard, as it is intended for conventional banks. An
Islamic standard issued by the Islamic Financial Services Board amending the Basel III standard
has been issued with the aim of applying it by Islamic banks. However, Basel III remains the most
accepted standard in the international banking arena. This study aims to identify the most
important differences between the two capital adequacy standards issued by the Basel III Accord
and the Islamic Financial Services Board, in addition to identifying the extent to which they can be
applied at the level of Islamic banks, The study concluded that there are some similarities between
the two standards, in addition to some differences, and that their application to Islamic banks is
possible, but the Islamic Financial Services Board standard is considered the most appropriate for
these banks.
