Abstract: The banking sector is recognized as one of the cornerstones of the contemporary economy when it comes to the security of investor funds and deposits. To guarantee the security of money, the Nigeria Deposit Insurance Corporation and other regulatory bodies have put in place a variety of adjustments and regulations. Numerous environmental factors have been linked to a decline in bank performance over time, according to published research. Finding out how peace accounting affected the financial performance of Nigerian listed deposit money banks was the study's main goal. The study adopted the Ex Post Facto Research Design. The Population was 14 listed deposit money banks. The sample size was 10 selected using a purposive sampling technique for a period of 10 years (2013-2022). Data was analyzed using inferential statistics. The result shows that Peace Accounting measured with Corruption, Security, and Foreign Aid had a significant effect on Return on Asset (Adj $$R^{2} = 41.8$$, F-stat (5, 96) = 89.01, p < 0.005). Peace Accounting had a significant effect on Net Profit Margin (Adj $$R^{2} = 40.7$$, F-stat (5, 96) = 142.80, p < 0.005). The study concluded that Peace Accounting had a significant effect on the Financial Performance of Deposit Money Banks listed in Nigeria. The study recommended that there is the need for the government to avoid policies and activities of the government of a country that can lead to conflicts that might disrupt economic activities thereby affecting performance, so that more funds can be committed towards tackling insecurity thereby improving the Return on Assets of Deposit Money Banks.
