Obligatory Reinsurance


Obligatory reinsurance is a type of reinsurance agreement in which an insurance company is mandated to transfer or cede a specific portion of its risks or insurance policies to a reinsurer. The purpose of this arrangement is to spread the risk and increase the financial stability of the primary insurer. This type of reinsurance contract typically applies to all policies covered by the agreement, providing continuous support and coverage for the insurer.


The phonetics of the keyword “Obligatory Reinsurance” in the International Phonetic Alphabet (IPA) are:Obligatory: /əˈblɪɡətɔːri/Reinsurance: /ˌriːɪnˈʃʊrəns/

Key Takeaways

  1. Risk sharing and security: Obligatory reinsurance is a form of risk management in which an insurer will cede a predetermined portion of its risks to a reinsurer. This helps insurance companies maintain financial stability by sharing the risk of large losses with reinsurers, who have a greater capacity to absorb losses due to their diverse portfolios and large capital base.
  2. Automatic coverage and streamlined underwriting process: In obligatory reinsurance, insurance companies cede risks to reinsurers automatically, according to predetermined agreements. This helps simplify the underwriting process for insurers, as they do not have to enter into negotiations with reinsurers for each individual risk. As a result, this saves time and operational costs for insurance companies in the long run.
  3. Strengthening insurance market: Obligatory reinsurance contributes to the overall stability and efficiency of the insurance market. By sharing risks, insurance companies can more readily fulfill their promises to policyholders while reinsurers gain access to a larger pool of diversified risks. This leads to a more robust and resilient insurance industry, which ultimately benefits both insurers and their customers.


Obligatory reinsurance is important in the business and finance sector because it enables insurance companies to manage their risks more efficiently and maintain financial stability. Through obligatory reinsurance agreements, insurers transfer a predetermined portion of their liabilities to a reinsurer, who in turn, assumes responsibility for covering a specific share of the insured risks. By spreading the financial burden across multiple parties, obligatory reinsurance ensures that no single entity is overwhelmed by potential losses, safeguarding insurers against insolvency and providing policyholders with increased security and confidence in the insurer’s ability to pay out claims when needed. Ultimately, this bolsters the overall stability and solidity of the insurance industry, which is vital to the smooth functioning of the global economy.


Obligatory reinsurance, as a key aspect of the insurance industry, serves primarily to spread risk and maintain stability for insurance companies. Its purpose is rooted in the fundamental concept of diversification, allowing insurers to mitigate the impact of potential losses from large-scale events or the accumulation of risks associated with underwritten policies. By ceding a portion of their risks to a reinsurer, the insurance company can maintain sound financial health and protect its solvency, all while continuing to expand its capacity for issuing coverage. This enables the insurer to accept a larger volume of policies, catering to diverse market needs, and also helps safeguard against uncertainties in the ever-changing landscape of risks. In turn, the reinsurer benefits by receiving a share of the premiums collected by the primary insurer, often leading to a fruitful partnership for both parties. In addition to reinforcing the fiscal stability of insurance companies, obligatory reinsurance plays a significant role in fostering a robust, competitive market. The compulsory nature of the practice ensures that risk distribution is widespread, thereby limiting the chances for monopolisation and fostering a diverse, flexible insurance sector. By enhancing the resilience of insurers and fostering collaboration among them, obligatory reinsurance promotes confidence among policyholders and stakeholders in the insurance ecosystem. The resulting favorable atmosphere then encourages investment and growth in the sector, ultimately benefiting the economy as a whole. In summary, obligatory reinsurance is a cornerstone of the insurance industry, providing essential risk mitigation and driving competition, stability, and growth.


1. Catastrophe Reinsurance: In the aftermath of a major natural disaster like a hurricane, earthquake, or flood, insurance companies may face massive claims from policyholders. To cover their potential losses and maintain financial stability, insurance companies will often purchase obligatory reinsurance – specifically in this case, catastrophe reinsurance. This type of reinsurance takes effect when payouts exceed a predetermined threshold, allowing the insurer to transfer a portion of their risk to the reinsurer and protecting them from financial collapse. 2. Terrorism Risk Reinsurance: Insurers also utilize obligatory reinsurance to manage the financial risks associated with terrorism-related losses. Following the September 11, 2001 attacks in the United States, the cost of providing terrorism risk insurance drastically increased due to the uncertainty and magnitude of potential losses. As a result, insurers sought out obligatory reinsurance policies specifically tailored for terrorism-related risks. These policies help insurers cover potential losses from terrorism attacks, making it more feasible to provide terrorism risk coverage to their clients. 3. Aviation Insurance: Aviation insurers cover potential losses resulting from aircraft accidents or incidents. Given the high costs associated with aviation accidents, it is essential for insurers to manage their exposure to such risks. Therefore, they often turn to obligatory reinsurance to protect themselves from significant financial losses which might arise from aviation-related claims. By purchasing obligatory reinsurance for aviation risks, insurers can transfer a portion of their risk to reinsurers, ensuring that they remain financially stable even in the case of major aviation accidents that generate substantial claims payouts.

Frequently Asked Questions(FAQ)

What is obligatory reinsurance?
Obligatory reinsurance is a type of reinsurance agreement in which the primary insurer (the ceding company) is required to cede a specific portion of their risks to the reinsurer. This creates a long-term relationship between the parties, allowing the primary insurer to share potential risks and stabilize their business.
Why is obligatory reinsurance important in the insurance industry?
Obligatory reinsurance helps insurance companies manage risk, reduce exposure to financial losses, and stabilize their balance sheets. It allows insurance companies to cede a portion of their risk to a reinsurer, leading to more stable profits, financial strength, and improved capacity for underwriting new policies.
What are the main types of obligatory reinsurance?
The two primary types of obligatory reinsurance are proportional reinsurance and non-proportional reinsurance. In proportional reinsurance, the reinsurer agrees to cover a percentage of the primary insurer’s risk, sharing both premiums and losses proportionally. Non-proportional reinsurance works on a more complex structure where the reinsurer only covers losses exceeding a specified limit or threshold.
How is the reinsurance premium calculated in an obligatory reinsurance agreement?
In a proportional obligatory reinsurance agreement, the reinsurance premium is generally calculated as a percentage of the primary insurer’s premium income, which corresponds to the reinsurer’s share of risk. In a non-proportional arrangement, the premium depends on several factors, such as historical loss data, the insurer’s risk profile, and the specific coverage structure.
Can an insurance company choose to forgo obligatory reinsurance?
While an insurance company may choose not to engage in obligatory reinsurance agreements, doing so could expose the company to more financial risks. Obligatory reinsurance helps maintain financial stability and balance sheet strength, both of which are crucial for an insurer’s long-term success.
How does obligatory reinsurance differ from facultative reinsurance?
Obligatory reinsurance is a long-term, ongoing agreement that focuses on a specific portion of the insurer’s business, while facultative reinsurance is a one-off, case-by-case agreement that provides coverage for individual risks or policies. Facultative reinsurance allows insurers to seek reinsurance for risks not covered by obligatory agreements or when they want additional coverage for a particular policy.
Can a reinsurer refuse to cover a specific risk in an obligatory reinsurance agreement?
Since obligatory reinsurance is a binding agreement between the insurer and the reinsurer, specific risks identified within the contract must be covered. However, insurance companies can establish certain clauses and exclusions in the treaty to provide limitations or clarify the covered risks, which can be negotiated and agreed upon by both parties during the contract negotiation process.
