The liquidation of a subsidiary in the banking sector is a strategic step with a significant impact on the financial performance, reputation, and sustainability of the parent company. This study aims to analyze the factors that drive liquidation, both internal such as financial performance, mismanagement, and legal compliance, as well as external such as market changes, natural disasters, and globalization pressures. Data were collected through academic literature review using qualitative approaches and data triangulation to improve the reliability of the results. The results of the study show that poor liquidity management, both due to internal and external factors, is the main cause of liquidation.
