In this article, the factors affecting the level of problem loans are studied. Many factors such as macroeconomic, financial, social, and personal factors are discussed in the analysis. Macroeconomic conditions, especially inflation, unemployment, and credit rates, credit problems will have a big impact on the level. Also, the credit policies of financial institutions and the low level of financial literacy may also have a negative effect on the ability of credit borrowers to repay their debts. Social factors, for example, people not being able to accurately assess their financial situation or not being well prepared for economic shocks, cause the level of problem loans to increase. Personal factors, including the borrower's ability to make rational financial decisions, personal past economic experience, or problems related to forgotten obligations play a large role.
