Apart from political stability as a result of Stefan's ability to keep a distance from both the Ottoman Empire and the Kingdom of Hungary, stability was also helped by the very rich silver mines, Srebrenica and Novo Brdo, some of the wealthiest in Europe at that time.
Peale poliitilise stabiilsuse, mis oli Stefani võime tulemus hoida end eemal nii Osmanite riigist kui ka Ungari kuningriigist, aitasid stabiilsusele kaasa ka väga rikkad hõbedakaevandused Srebrenica ja Novo Brdo, ühed rikkamad selle aja Euroopas.
