The article analyzes the level of competition of insurance product offerings in the following four markets using the Russian market as an example: (1) life insurance, (2) accident and disease insurance, (3) voluntary health insurance and (4) pension insurance. The purpose of the study is to assess competitive dynamics in the insurance product markets during the period under review. Relevant data of the Expert Rating Agency for 2018-2021 were used as the study basis. The study methodology is based on the assessment of the competitive situation using the SV matrix, which is based on HTSV (level of differentiation within the dominant group) and CRSV (cumulative market share of the dominant group). The study shows that the Russian insurance market in 2018-2021 was quite diverse in terms of dominance. Most individual insurance products belong to the B4 quadrant of the SV matrix (a natural oligopoly), yet, the situation with the dominant group regarding types of insurance under study is significantly different, since the number of dominant players varies from 2 to 10, considerably affecting a real consumer choice, however, among the markets under study, there is none with low concentration or without a dominant group or dominant leader. In the VHI market, the choice is quite large, while the presence of a big dominant group of eight companies suggests formation of the two-tier companies. The top echelon sets quality standards and dominates by price, while other companies can compete with the leaders due to niche offerings and price factors. The pension insurance market is an example of a significantly reduced consumer choice: in 2018, it is in the RO quadrant with a relatively “weak” dominant group, while by 2021, a hardly differentiated oligopoly of 5 companies has been formed, controlling 95% of the market. Emerging players with the market and institutional opportunities similar to SOGAZ make significant changes in the market structure, as in the case of personal insurance market, wherein SOGAZ has absorbed the largest player, transferring the market from an oligopoly of seven companies to the actual dominance of the one.
competitive analysis, life insurance, market competition, Russian insurance market, SV Matrix
Competitive analysis of the market of individual insurance products is substantiated by economic changes in all countries associated with the pandemic, which could not but affect the insurance market. Formally, there is a fairly broad market of individual insurance products in each country, but a real consumer choice may be limited by the dominance of large insurance companies in certain types of insurance products.
Using the Russian market as an example, the article attempts to evaluate competition of insurance products, as well as changes in competition during the period under study in the following four markets: (1) life insurance, (2) accident and disease insurance, (3) voluntary health insurance and (4) pension insurance.
The issue of competition between individual insurance products has already been studied in various aspects.
Unfortunately, current research on competition in the Russian insurance market is quite limited in terms of the tools used (mainly, it is CR and HHI assessments), making it impossible to assess the real choice of insurance products.
From the consumer point of view, the market of accumulative life insurance products is an alternative to bank deposits. Therefore, in order not to miss potential sales opportunities, all leading banks are actively offering accumulative life insurance as part of their services. In 2019, the share of policies sold by banks accounted for 85% of the total volume (
An essential part of the life insurance market is life insurance of the borrow or credit life insurance. As a result, there is a direct relationship between the volume of the life insurance market and the volume of loans issued, which depends on the key rate determined by the Central Bank of Russia (
Paper (
The accident and disease insurance market is also directly affected by the population demand for loans (
In fact, the main competitor of VHI in Russia is compulsory health insurance (CHI), deductions for CHI funds are subtracted from the employee’s real salary regardless of the employee’s will. According to some researchers, many Western countries do not have free health care or it is rather limited, therefore insurance products are in much greater demand than in Russia, encouraging a more active competition for customers (
As a result, in Russia, the main buyers of VHI are legal entities that purchase policies for their employees – 87.7% of the market volume by the end of 2020 (
According to Fatkhlislamova G.F. (
In general, most researchers use standard indices to analyze competition in the insurance market (most often CR and HHI, less often – the Lerner index, HT, absolute concentration index (ACI), Lorenz curve) and analyze entry-exit barriers and institutional advantages of players. At the same time, everyone points out oligopoly or monopolistic competition, however no one analyzes the level of competition between the market leaders, among whom most consumers primarily choose. It is intuitive that if there are 100 companies in the market and each has 1% of the market, then it most likely indicates a broad consumer choice. However, if one of the 100 companies has 95% of the market, a real consumer choice hardly exists. Let’s look at this issue in more detail from the consumer point of view.
What number of offerings (or insurance companies in the market) can imply availability of consumer choice?
As written in (
However, let us not ignore the fact that the consumer behavior is not always rational. For example, paper (
It is also important that one and the same need can be met by insurance products of different types. For example, coverage for tick bites (insurance policy), which is popular in many Russian regions, can be provided both as part of VHI policies and as accident and disease insurance (
The main purpose of this study is to determine competitive dynamics in offerings in the insurance product markets during the period under review. The study considers the following insurance product markets as individual insurance product markets:
To analyze consumer choice, we will analyze competition in each of the markets and consider relevant changes in 2018-2021. If a certain segment of the insurance market has a low concentration of business and low level of differentiation between players, then we will assume that the market is close to perfect competition and the consumer does have a choice. If there are groups of dominant companies in the market or a high concentration of business, we will consider in more detail the nature and specific features of this competition.
Accordingly, our approach will consist of the following steps:
The use of the SV matrix (
The Lind index used in the matrix is designed to determine the presence of a dominant group (i.e. two or more companies) and its size in the analyzed market. In case when there is only one dominant company in the market, the Lind index does not show it. Therefore, we will identify such cases using the Herfindahl-Hirschman Index (HHI): if there is one leader with a high market share, then HHI will show a high concentration of the market, and we will analyze it separately. As a rule, in all countries, an indicator of less than 1000 is considered the indicator of low concentration of markets, and over 2000 (in the U.S. over 2500) is a sign of high concentration (
More information about coefficient calculation can be found in (
Based on the logic of constructing the SV matrix, if the market is in the B4 quadrant, then the companies of the dominant group seek to protect the existing oligopolistic equilibrium by preserving the existing ones and creating additional barriers to entry of any new companies. In this situation, we can say that the consumer choice will be limited by various institutional and market advantages of the dominant companies. This may manifest itself in the fact that, for example, to provide a particular service, an organization may require an insurance policy issued by a limited number of insurance companies.
In the RO quadrant, the consumer choice will be much wider, since companies within the dominant group actively compete not only with other companies, but also with each other, and therefore it is quite difficult for them to unite, which has a beneficial effect on the consumer choice options.
The consumer has a somewhat narrower choice in the I and G segments, but in order to assess the availability of a real choice, it is necessary to analyze in detail the number of players in the dominant group, as well as the market share of the leader. If the leader’s share is over 50% (
Additionally, in many cases it will be necessary to analyze possible institutional advantages of the market leaders, since if, for example, the bulk of buyers of one of the products is state-owned companies, then it is possible that insurance companies with state participation may have advantages over the rest of the market participants.
Based on Expert RA data for 2018 – 2021 (https://raexpert.ru/rankings/insurance/2021/) we will analyze how the situation in the voluntary insurance market has changed during the COVID-19 pandemic in terms of the overall market dynamics and its individual segments, as well as the level of dominance and competition in these markets (see Table
Main indicators of the individual insurance market – amount of the collected insurance premiums in 2021

1.1 Total amount of premiums by type of voluntary insurance (including incoming reinsurance) | 1 626 708 |
1.1.1 Life insurance premiums | 524 402 |
1.1.1.1 Life insurance premiums (excluding pension insurance) | 522 232 |
1.1.1.1.2 Life insurance premiums of the borrower | 136 084 |
1.1.1.2 Pension insurance premiums | 2 170 |
1.1.2 Non-life insurance premiums | 1 102 306 |

1.1.2.1.1 Accident and disease insurance premiums | 262 568 |
1.1.2.1.2 Health insurance premiums | 200 317 |
In general, the Russian voluntary insurance market consists of the following two large segments “Life insurance” and “Non-life Insurance”. In line with the purpose of the study, we will focus on the market segments related to the life and health of the population, namely, we will consider “Life insurance premiums”, “Personal insurance premiums”, excluding “Property insurance premiums”.
The table below presents the authors’ calculations of HHI, Lind, HTSV and CRSV, corresponding quadrant of the SV matrix, as well as the scale of each market in 2018-2021 for reference.
Therefore, the size of the dominant group (as will be specified below) was evaluated by experts, and then CRSV, HTSV and the corresponding quadrant of the SV matrix were calculated.
Table
We can observe a similar situation in the accident and disease insurance segment in 2018 (see Table
In 2021, the situation related to this type of insurance resembles the one in 2018: SOGAZ is in the lead with a market share of over 51%, followed far behind by other companies. As in the previous case, this segment can be attributed to quadrant I of the SV matrix (CRSV= 51.05%, HTSV=1).
Next, we will separately consider the following two segments: life insurance (1.1.1) and personal insurance (1.1.1.2)
It is important to note that since pension insurance premiums account for a very small part of the “Life Insurance” segment (about 0.4%, according to Table

In 2021, a third of the increase in premiums in the insurance market is due to the life insurance segment (94 out of 290 billion rubles). According to the National Rating Agency, in 2021, “the main factors of the premium growth were the record volume of mortgage and consumer loans, as well as low deposit rates combined with the introduction of taxation of interest income on deposits” (National rating… 2022)
The figure below outlines the SV matrix showing these three segments of the insurance market.
Let’s consider each of the segments separately.
As the SV matrix shows (see Figure
SV matrix for life insurance premiums in Russia, 2018-2021. Source: compiled by the authors based on the data presented in Table
Rosgosstrakh Life, which is 5th in the ranking in 2020 and 2021, lagged more than twice behind Renaissance Life, which ranks fourth.
According to the National Rating Agency, “After information disclosure standards were introduced, banks – the main sellers of life insurance contracts – shifted their interests towards other products, both insurance (for example, accumulative life insurance) and non-insurance. The problem of misselling has become less acute, yet impossible to be fully eradicated, creating reputational risks in this segment. The segment development is also negatively affected by low level of accumulation in the population income, competition due to other investment products, including conditions for tax deductions, as well as lack of simplified identification of customers» (National rating… 2020).
From 2018 to 2021, this market segment moved from the G quadrant to B4 (see Figure
In this case, we can assume that a real consumer choice is missing, since 2 companies control three quarters of the market.
In Russia, as of 2019, there were 46.5 million pensioners, including 36.7 million receiving an old-age pension (

In terms of competition in this market in 2018-2021, this market segment has moved from the RO quadrant to B4, which means a significant increase in the share of dominant players (from 65% in 2018 to 95% in 2021). The following 5 companies (Sovcombank Life, PPF Life Insurance, Geopolis, Ingosstrakh-Life Insurance Company, Capital Life Life Insurance) formed the dominant group in 2021 (see Table

SOGAZ-LIFE Insurance Group | 0.84% ▼ | 1.52% | 1.20% | 1.50% |
Formally, the size of the dominant group has been constantly increasing since 2018, indicating expansion of the consumer choice, but in reality, in the end of 2021, an oligopoly of 5 companies controlled 95% of the market. This may lead to negative consequences, however, most likely this will not happen, since pension insurance is considered by consumers on a par with non-state pension funds, whose offers expand their range of choice (
Conspicuous is a low share of SOGAZ-Life, which is part of the SOGAZ Group, but this is probably caused by too small a volume of the pension insurance market compared to the rest.
The personal insurance market showed significant changes under the study period, having successively passed all 4 segments in 4 years, although all segments of this market, as shown in Figure

This is due to the fact that the first largest company in 2018 (VTB Insurance with a market share of 17.3%) was sold to SOGAZ Insurance Group. The transaction scope included all companies of VTB Insurance group, including VTB Life Insurance and VTB Health Insurance (
Emergence of a strong leader in this market has moved the market from a poorly differentiated oligopoly in 2018 to a highly differentiated one in 2021. The dominant group of 9 companies has been formed by 2021, since companies with the ranking number 10 and under (Soglasie) began to lose their shares (see Table

If the companies of the dominant group stick together, then a gradual decrease in differentiation between companies and evolution of the market into the B4 segment can be expected.
In any case, there is a formal availability of a fairly broad choice for consumers, however, the leader with a market share of almost 45% also makes it possible to hypothesize that SOGAZ may have strong competitive advantages over other companies in some segments of this market, possibly relying on institutional advantages.
This market is so peculiar that the use of the SV matrix apparatus required manual adjustment in two periods (see Table
