The article analyses conceptions of both, the economic security and financial security of the state, in respect to a recent increase of attention given to assuring the state’s economic security while emphasizing mostly the financial factor. Therefore, a thorough analysis on the two conceptions, as well as, on their interrelation, based on scientific literature, revealed that state’s financial security and stability can reflect the economic security of the state only to some extent. The performed scientific practical research verified the hypothesis, which emerged during theoretical research, that financial security and stability cannot fully ensure the economic stability of the state.
