The efficiency of banks is an important factor that effectively contributes to the stability of the world financial system, thus reducing financial failure rates of banks and international financial crises that leads to the stability of the global financial system. This study aims to investigate whether the efficiency of Egyptian banks adversely affects financial stability. A sample of 30 banks operating in Egypt was selected to answer this question using the data envelopment analysis (DEA) approach and financial ratios. This study enables the Central Bank of Egypt to identify which banking system (Islamic banks or traditional banks) is more efficient and contributes significantly to boost economic growth. Results revealed that the efficiency of banks is a core factor to affect financial stability. The statically explanatory power of this effect is significant but weak at 14.1% for all Egyptian banks, 6.3% for traditional banks, strong for traditional banks with Islamic window at 22%, and stronger for Islamic banks at 55%. Consequently, the Islamic banking system in Egypt is more efficient compared to traditional banks and has a greater impact on financial stability as one of the pillars of financial inclusion to boost economic growth in Egypt.
