Financial crises, such as the Great Financial Crisis of 2007–2009 and the COVID-19 Crisis of 2020–2021, lead to high volatility in financial markets and highlight the importance of the debate on the Efficient Markets Hypothesis, a corollary of which is that in an efficient market it should not be possible to systematically make excess returns. In this paper, we discuss a new empirical measure—Excess Trading Returns—that distinguishes between market and trading returns and that can be used to measure inefficiency. We define an Inefficiency Matrix that can provide a complete, empirical characterization of the inefficiencies inherent in a market. We illustrate its use in the context of empirical data from a pair of model markets, where information asymmetries can be clearly understood, and discuss the challenges of applying it to market data from commercial exchanges.

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).
