Bank is one of the most important pillars of economy activities. However, banking sector has a real potential crisis threat. Alongside with the steady current global banking development, financial crises that have happened clearly affected global economy. Based on that situation, BIS (Bank for International Settlement) – an international financial standard setting organization, realizes the urgency to establishan international financial standard and supervision to anticipate future potential financial crises. This research aims to identify how Capital Adequacy Ratio Standard in Basel Capital Accord (II) based on Islamic law perspective. The research is conducted by analyzing Basel Capital Accord published by BIS. The research uses library research method to find out the aimed result. The focus is on the 1st pillar of Basel II publication that is Minimum Capital Requirements (CAR) policy. CAR, as an Islamic economics policy, will be analyzed using falāḥ approach. Falāḥ is an Islamic economics objective that consists of happiness, success, accomplishment or good luck concept. The earthly dimension of falāḥ has some parameters that can be used to analyze Islamic economics policy. Additionally, the Islamic fiqh maxim takes part in analyzing the policy. The maṣlaḥat concept in fiqh maxim approach shares aim with falāḥ concept in the sense that all of sharia law aims for success, happiness, eternal survival etc. The maṣlaḥat can be accomplished by extinguishing mafsadat or seizing maṣlaḥat. The maṣlaḥat aspect is essential to determine the compatibility Basel Capital Accord with jurisprudential maxim i.e harm must be dispelled (al-dharāru yuzāl). The conclusion results are, 1) Basel Capital Accord focuses on macro-prudential aspect in order to anticipate potential financial crises, 2) beneficial/interest (maṣlaḥat) aspects of the hereafter, cooperation principle, justice, fairness and the prohibition of exploitation are not the core value of Basel Capital Accord frame work, thus 3) the achievement of maslahat as intended by sharia i.e. jurisprudential maxim are not convincing. Therefore, 4) Basel Capital Accord as a regulation basis is not in line with jurisprudential maxim i.e harm must be dispelled (al-dharāru yuzāl).
