The objective of this thesis was to analyze the public debt management strategies of the Republic of Croatia over the period from 2007 to 2026, with a particular focus on their effectiveness and successful implementation. Public debt is one of the key economic concepts as it significantly impacts economic expectations, individual behavior, and market movements. The methodology used in the research includes secondary data sources from relevant institutions such as the Ministry of Finance, the Croatian National Bank, and Eurostat. A descriptive method was applied for the theoretical part, while statistical methods were used to present data through charts and tables. The historical method allowed for the comparison of data over different time periods, and induction and deduction methods were employed to draw conclusions. Public debt is categorized according to several criteria, including institutional scope, maturity, currency structure, and interest rates. The main challenge of debt management is ensuring an optimal structure of maturity and currency, as well as minimizing the risks associated with fluctuating interest rates and currency risks. The conclusion of the thesis highlights that improving public debt management is crucial for the stability of the financial system. It is necessary to continue expanding and diversifying the investor base and strengthening the domestic market for government securities to reduce the risk of external shocks and increase the liquidity of the domestic financial market.
