Capital buffers can be used as capital reserves in times of various economic shocks so as to minimize risks faced by banks. A bank that has a high capital buffer reflects a high CAR as well, while a CAR that is too high is also not profitable for the bank, because this capital should be used for lending and investing in an effort to maximize profits. This study aims to determine the determinants of going public banking capital buffer in Indonesia for the period 2014 to 2018. The sample selection is based on purposive. Acting as the dependent variable is the capital buffer and the independent variables are ROE, NPL, Lag of capital buffer (〖BUFF〗 _ (t-1)), Size and GDP. This study used multiple regression analysis. The results of this study indicate that the selected determinants of the capital buffer of going public banking in Indonesia are adjustment costs and the business cycle.
