With respect to the manner of the funds management, municipalities may find them-selves in the situation, where no sufficient funds are in their budget for covering costsand expenses such as maintenance, construction and reconstruction of infrastructure,or the development of its territory. It may in turn lead to the need of looking some ex-ternal sources, either in the form of non-repayable or repayable funds, and thus to in-debtedness. In the Czech Republic, the issue of indebtedness of municipalities and lo-cal authorities is one of the frequently discussed subjects. The reason is the balance ofindebtedness of municipalities (so far growing), which quickly accelerated in the post-revolutionary years and now affects more than a half of municipalities. If municipalitiesdo not dispose of sufficient financial resources to finance current and capital expendi-tures, they must find external sources. This brings not only positive effects in the formof increasing the quality of life in municipalities, but also negative effects in the formof the inability to repay the above-mentioned foreign resources and thus increase therisk of financial instability of municipalities. Therefore it is very important to superviseand monitor public sources and their use. One of the significant monitoring indicatorsis the liquidity of municipalities. Authors of this article aim to present an effective toolfor observing indicators of indebtedness or liquidity – the app Finance stability of mu-nicipalities of the Moravian-Silesian region. For an illustrative overview of specific re-sults, an indicator of the share of total debt in the current budget balance was selectedand municipalities were monitored in the period from 2010 to 2016. In the current pe-riod, the financial situation of municipalities was affected by the pandemic COVID-19.Therefore, it is important to know the current development of monitored indebted-ness and liquidity indicators.
