ADIB and Qatar Islamic Bank Battle for a Place Among the World's Top Five Islamic Banks

The landscape of the world's largest Islamic banks has been undergoing rapid transformation in recent years, driven by the growing demand for Islamic banking services and intensifying competition among major Gulf financial institutions for leading positions within the industry.

Against this backdrop, Abu Dhabi Islamic Bank (ADIB) and Qatar Islamic Bank (QIB) have emerged as two of the region's and the world's leading competitors, particularly as both banks continue to expand while following increasingly different growth trajectories.

According to data as of March 2026, ADIB ranks as the fifth-largest Islamic bank globally by total assets, while Qatar Islamic Bank occupies the sixth position. Over recent years, ADIB has steadily strengthened its lead and widened the gap over its Qatari rival across assets, deposits, and financing portfolios.

ADIB's total assets reached US$78.15 billion at the end of March 2026, compared with US$61.48 billion for Qatar Islamic Bank during the same period.

ADIB also maintained a clear advantage in deposits, which stood at US$65.16 billion at the end of March 2026, versus US$52.20 billion for Qatar Islamic Bank.

The bank also preserved its leadership in financing activities, with net customer financing totaling US$52.76 billion by the end of March 2026, compared with US$40.18 billion for Qatar Islamic Bank over the same period.

The shift in the competitive landscape becomes even more apparent when examining growth rates over the past three years—from the end of 2022 through March 2026. During this period, ADIB recorded 70.3% growth in total assets, compared with only 21.6% for Qatar Islamic Bank.

This strong performance enabled ADIB to overtake Qatar Islamic Bank by the end of 2023, before further widening the asset gap to US$16.67 billion by the end of March 2026.

In terms of deposits, ADIB posted robust growth of 73.2% over the past three years, while Qatar Islamic Bank recorded a marginal decline of 0.05% during the same period.

As a result, the deposits gap between the two banks expanded to US$12.96 billion by the end of March 2026, up from approximately US$3.39 billion at the end of 2022.

On the financing front, ADIB achieved 79.9% growth in net customer financing over the past three years, compared with 22.6% growth for Qatar Islamic Bank.

This enabled ADIB to gradually narrow the financing gap before overtaking Qatar Islamic Bank by the end of 2024, ultimately expanding its lead to US$12.58 billion by the end of March 2026.

ADIB's advantage extends beyond growth momentum to profitability and operating efficiency. During the first quarter of 2026, the bank generated net profit of US$496.85 million, significantly exceeding Qatar Islamic Bank's US$270.48 million over the same period.

ADIB also outperformed its competitor in profitability metrics, posting a return on average assets (ROAA) of 2.57% during the first quarter of 2026, compared with 1.77% for Qatar Islamic Bank.

In addition, ADIB recorded a return on average equity (ROAE) of 23.38%, versus 11.77% for Qatar Islamic Bank, reflecting superior efficiency in utilizing both assets and shareholders' equity to generate earnings.

On the capital front, ADIB also enjoys a strong relative advantage, with capital totaling US$988.76 million at the end of March 2026, compared with US$648.55 million for Qatar Islamic Bank. This provides the bank with greater financial flexibility to support its future expansion plans and strengthen its resilience against potential shocks.

These indicators suggest that competition between ADIB and Qatar Islamic Bank is no longer limited to maintaining their positions among the world's largest Islamic banks. Instead, it has evolved into a race defined by the speed of expansion, the efficiency of growth, and the ability to generate sustainable profitability.

While ADIB has successfully consolidated its leadership over recent years, maintaining this momentum could further reshape the competitive landscape among the world's leading Islamic banking institutions, particularly as the global Islamic finance industry continues to expand at an accelerated pace.
