How loyal are Islamic banking customers?

Islamic banking is a growing industry, however still much smaller than conventional finance, even in Muslim majority nations. In the UAE, 76% of residents are Muslim, yet Islamic banks only hold 19% of banking assets. The question is: why would Muslims choose conventional banks when Halal options are available? Research has found that the chief reason was a better rate of return. A recent study shows that 25% of Islamic banking customers preferred conventional banks and products when interest rates were the same. When conventional banks offer 1% better interest rates, the share that would switch to conventional banks rose from 25% to 44%. About 25% of Islamic banking customers came to it because of their employers, while 35% use both Islamic and conventional banks. A group of about 40% of Islamic banking customers are truly loyal to Islamic banking, most likely for religious reasons.
