The concentration of the insurance market is an objective process that evolves by the trends of the world market laws. In practice, many countries use a whole set of indicators that are developed by the world economic science to estimate the concentration level in different sectors of the economy. Official statistics, unfortunately, give only a fragmentary assessment of the concentration level of the domestic insurance market. The National Financial Services Commission considers two indicators: the concentration ratio and the Herfindahl-Hirschman index. The analysis of these indicators is provided on the whole market and separately on the non-life and Life insurance markets only by the volume of insurance premiums. Such an assessment is very general, and the insurance market of Ukraine remains informationally closed.

Studies have shown that the level of market concentration is related to the processes of monopolization and competition. Significant concentration on the life insurance market, which in turn defines it as moderately monopolized and not a significant concentration on the risk insurance market, which has a significant level of competition.

However, among a large number of insurance companies in the insurance market other than life insurance, it is possible to single out leaders who, compared to their competitors, have a significant amount of insurance payments and hold a significant share of the market in terms of insurance premiums, assets and what is important for customer - the proper level of payments, which is confirmed by the amount of insurance claims. In the market of risk insurance of Ukraine the leaders are such system-forming insurance companies as  «UNIKA», «IG TAS»,  «ARSENAL UKRAINE»,  «PZU UKRAINE»,  «АХА  INSURANCE» and «INGO UKRAINE».
