This study aims to examine the impact of the Central Bank of Iraq’s decision to increase the capital of private Iraqi banks on their financing, operational, and investment decisions. The main research problem lies in evaluating the extent to which the capital increase affects private banks’ decisions, as well as the challenges these banks face in raising their capital. The study hypothesizes that there is a statistically significant relationship between capital and financing, operational, and investment decisions after the capital increase. The findings indicate that private Iraqi banks have encountered several challenges in increasing their capital, particularly regarding the valuation of newly issued shares and the difficulty of disclosing the capital increase. Despite these challenges, the results demonstrate a positive impact of capital increase on enhancing the decision-making processes of Iraqi banks. Ultimately, this contributes to achieving the Central Bank of Iraq’s objective of promoting economic stability and strengthening public confidence in private Iraqi banks.
