The size of a bank's assets doesn't have a clear impact on its financial performance, according to a study on Kuwaiti banks. Some think bigger banks save money and do better financially, while others believe they struggle with bureaucracy and make less profit. The study looked at data from 10 Kuwaiti banks between 2008 and 2018. The results showed that bank size didn't have a significant effect on profitability, but there was a clear link between shareholder equity and bank profitability.
