The changing environment and current economic conditions force business entities to react quickly to changes. They strive simultaneously to be profitable and to improve their competitive position by responding to the preferences and needs of customers/customers. In order to meet their expectations, business entities must apply more and more diverse management tools to improve their efficiency and effectiveness. Likewise, in order to achieve the desired effects, business entities increasingly and frequently use controlling tools, an idea that appeared already in the Middle Ages, and was widely popularized in the second half of the 20th century. Controlling is a management tool in companies, the function of which is to help the management to react quickly to changes in the environment and thus to contribute to the adaptation to market requirements. Controlling is also one of the subsystems of management, which has the function of increasing business efficiency. Management and controlling are two functions in a company whose ultimate goal is long-term successful business. Today, controlling as a management function is implemented, not only in large, but also in smaller business entities that are beginning to notice the positive effects of controlling. In times of increasingly strong competition, what is necessary and what is expected from business entities is the formation of good strategies, and the positive effect of well-defined business strategies is reflected positively on business results. A prerequisite for this is the establishment of an effective controlling system. The global financial crisis, and then the economic crisis caused by the pandemic and the war in Ukraine, have affected, among other things, the operations of banks in the past few years. Banks in the Republic of Croatia, like other business entities, are not immune to the turbulence in the environment and the consequences of the economic crisis. The purpose of this work is to present selected strategic controlling tools that are used today in the banking sector using the example of the largest commercial bank in the Republic of Croatia.
