The article is aimed at assessing the level of financial security of Ukraine, using the instrumentarium for calculating the integrated indicators for each component, during the period from 2005 to 2016. As result of the research, a significant decrease in the level of banking security, security of the non-banking financial sector, as well as debt and budget security have been identified. There was also an unsatisfactory level of foreign exchange security during 2008–2010 and 2015, while in the course of 2006–2007, 2011–2012, in 2014 and 2016, the level was average. The integral indicator of monetary security during the researched period did not exceed the mark of 0,4 points, that is, its level did not reach even the average. In general we can note the average level of financial security in Ukraine in 2005–2007 and 2009–2013, but its level in 2008 and 2014–2016 was unsatisfactory. Prospects for future researches in this direction are improvement of scientific-methodical approaches to the assessment of financial security of the country and determination of ways and directions of increase of the level of financial security.
