The subject of this thesis is the role of internal and external mechanisms in corporate governance in the modern conditions of bank operations. Good and high-quality corporate management of the bank is important for the stability of the bank and the macroeconomic stability of the nation. Corporate governance is a much-discussed topic, both nationally and internationally. Corporate governance is related to the relationship between small and large shareholders, management and other interest groups. In order to achieve an increase in system efficiency and sustainable economic growth, it is important that the corporate governance system functions well. The basis of good corporate governance is a suitable combination of the right investor protections and the level of ownership concentration. High-quality corporate governance, using its internal and external mechanisms, enables all participants to fulfill their interests that originate from the operations of the banks themselves. Banks play a central role in the economy. They attract citizens' savings in the form of deposits and offer them means of payment for goods and services and finance business development. They are subject to stricter regulations than other entities, because they are responsible for protecting the rights of depositors, ensuring the stability of the payment system and reducing systemic risk.
