Abstract
Over the past few decades MENA countries have adopted major financial reforms in favour of more financial integration which has led to changes in financial systems in general and the banking system in particular, characterized by an increased privatization process, foreign bank penetration and changes in the banking competition intensity. These changes raise many questions for the financial stability preservation especially that several banks encountered many difficulties to adapt to this new context and various followed strategies did not save many banks from significant distress situations following a considerable rise of risks.
Thus, the principal aim of this paper is to study the impact of financial liberalization, banking market structure and quality of MENA institutions on the likelihood of suffering a systemic banking crisis and to seek the optimal structure of banking system able to preserve financial stability.
Hence, using aggregate balance sheet data from banks across 13 MENA countries from 1990 to 2009, the paper is specifically directed towards analyzing the changes in banking structures and their capacity to ensure banking stability.
After calculation of a global financial liberalization index for MENA countries, we test several hypotheses between liberalization, banking structure and banking stability in the region. Our estimations are based on a country-specific fixed-effects model.
Given the challenges that MENA countries face, the empirical results of this study should be timely and helpful for policymakers.

In reaction to theoretical and empirical contradictions of the structural models, nonstructural approaches were developed namely: the model of Panzer and Rose, the model of Bresnham and the model of Iwata.

the financial liberalization proxy – the deposit interest rate ceiling – is widely used in the literature but represents only one aspect of domestic liberalization.

The money and quasi money comprise the sum of currency outside banks, demand deposits other than those of the central government, and the time, savings, and foreign currency deposits of resident sectors other than the central government. This definition is frequently called M2; Total reserves comprise holdings of monetary gold, special drawing rights, reserves of IMF members held by the IMF, and holdings of foreign exchange under the control of monetary authorities. The gold component of these reserves is valued at year-end (December 31) London prices.

Considering that the institutional indicators are highly correlated with each other, we introduce them separately.
