Insurance is a means of managing financial risks by purchasing protection against unexpected losses. Insurers only agree to cover risks that they deem insurable, that is, risks that allow them to turn a profit. Insurable risks are typically pure risks, such as property damage or natural events like fires or floods, which embody elements of chance, definiteness, measurability, statistical predictability, lack of catastrophic exposure, random selection, and large loss exposure. Speculative risks, on the other hand, such as gambling and investing, are rarely insured because they lack the core elements of insurability. Insurers face the challenge of understanding and managing an array of financial and non-financial risks, including cyber threats, climate change, geopolitical conflicts, and the emergence of generative AI. They employ various techniques, such as risk pooling and scenario simulation, to navigate these complexities and provide financial protection to their clients.

Insurers only cover risks that are profitable
Insurance is a means of protection from financial loss in which, in exchange for a fee, a party agrees to compensate another party in the event of a certain loss, damage, or injury. It is a form of risk management, primarily used to protect against the risk of a contingent or uncertain loss. An entity that provides insurance is known as an insurer, insurance company, insurance carrier, or underwriter. A person or entity who buys insurance is known as a policyholder, while a person or entity covered under the policy is called an insured.
Insurance companies typically cover pure risks, such as property damage, but almost never cover speculative risks, such as gambling and investing. Pure risks embody most or all of the main elements of insurable risk. These elements are "due to chance," definiteness and measurability, statistical predictability, lack of catastrophic exposure, random selection, and large loss exposure. A pure risk includes any uncertain situation where the opportunity for loss is present and the opportunity for financial gain is absent. Speculative risks, on the other hand, might produce a profit or loss, such as in business ventures or gambling transactions. They lack the core elements of insurability and are almost never insured.
Insurance companies require policyholders to submit proof of loss (often via bills) before they will agree to pay for damages. Losses that occur more frequently or have a higher required benefit normally have a higher premium. Insurance companies will not cover catastrophic risks, which are severe losses deemed too expensive, pervasive, or unpredictable for the insurance company to reasonably cover. Life and health insurance providers, for example, rely on actuarial science and mortality and morbidity tables to project losses across populations.
In the context of health insurance, risk pooling is a fundamental concept. A health insurance risk pool is a group of individuals whose medical costs are combined to calculate premiums. Pooling risks together allows the higher costs of the less healthy to be offset by the relatively lower costs of the healthy, either within a plan or within a premium rating category. While larger risk pools are generally more stable, the key factor in determining premiums is the average healthcare costs of the enrollees. Attracting younger and healthier individuals helps keep premiums more affordable and stable for all members in the risk pool.

Pure risks are insurable, speculative risks are not
Speculative risks, on the other hand, refer to situations with three possible outcomes: nothing happens, there is a loss, or there is a gain or profit. These are risks that a risk-taker accepts voluntarily and are always the result of a conscious choice. Speculative risks are not insurable because they lack the core elements of insurability. They introduce the aspect of moral hazard, which refers to the tendency to not guard against risk when protected from its consequences. For example, a person who gambles at a casino does so voluntarily, knowing that there is a high chance they might lose their money. However, the presence of insurance coverage may encourage them to bet more, increasing their chances of loss as well as the insurer's.
Insurance companies require policyholders to submit proof of loss before agreeing to pay for damages. Pure risks can be insured by transferring the risk to an insurance company, which can predict loss figures in advance using the law of large numbers. Speculative risks, such as gambling and investing, are not insurable due to their unpredictable nature and the potential for financial gain.
While pure risks are generally insurable, it is important to note that not all pure risks are covered by all private insurers. For example, property damage due to flooding may be considered a pure risk, but it is typically not covered under homeowners' insurance policies. Similarly, life and health insurance providers may exclude certain catastrophic perils from their coverage.
In summary, pure risks are insurable because they are beyond human control, have two possible outcomes (loss or no loss), and do not offer any opportunity for financial gain. Speculative risks, on the other hand, are not insurable as they are voluntary, have three possible outcomes (no outcome, loss, or gain), and introduce the element of moral hazard. Understanding the distinction between these types of risks is crucial for financial and insurance planning.

Geopolitical conflicts and climate change increase risk
Geopolitical conflicts and climate change are two major factors that significantly increase risks and impact the insurance landscape.
Geopolitical Conflicts
Geopolitical conflicts refer to various phenomena, including political instability, tensions, military conflicts, terrorist threats, and geographical events that can have far-reaching regional or global consequences. These conflicts can directly and indirectly affect the global economy through financial markets, trade, and commodity price channels. For instance, the ongoing conflict between Russia and Ukraine has disrupted trade flows, caused supply chain issues, and impacted commodity prices, particularly in the energy sector.
Geopolitical risks are challenging to predict as their outcomes depend on the responses of various actors. However, these risks can lead to economic and political instability, ultimately resulting in violence and conflict. Terrorist events can trigger and escalate perennial disputes, endangering infrastructure, shipping routes, and resources. The Israel-Hamas conflict, for example, has the potential to escalate into a wider Middle Eastern conflagration, disrupting global oil supplies.
Climate Change
Climate change is already impacting lives worldwide, and its effects will persist even with effective emission reduction measures. Extreme weather events, such as heatwaves, storms, droughts, and floods, are becoming more intense, frequent, and prolonged, resulting in significant health and economic consequences. Climate-sensitive health risks disproportionately affect vulnerable communities, including women, children, ethnic minorities, poor communities, migrants, and older populations.
The complex network of feedback loops associated with climate change accelerates global warming and increases the risk of reaching definitive tipping points. The urgency to respond to accelerating transitions impacts insurers and stakeholders, including governments, as they strive to adapt to the changing landscape.
In conclusion, geopolitical conflicts and climate change increase risks by disrupting global stability, impacting economies, and endangering human lives and infrastructure. These factors present significant challenges that shape the insurance industry's efforts to manage and mitigate risks.

Cyber risks are a growing concern for insurers
As the world becomes increasingly reliant on the internet, cyber risks have become a growing concern for insurers. The cyber insurance market has almost tripled in size over the past five years, driven by the increasing digitization of businesses, more frequent and severe cyber events, digital interdependencies, and heavier regulation. The insurance industry plays a crucial role in mitigating these risks, but it also faces challenges in keeping up with the rapidly evolving nature of cyber threats.
The cyber risk landscape is dynamic and constantly changing, with new threats emerging daily. Organizations face a constant battle to protect themselves from a wide range of threat actors, including lone hackers, organized crime operations, and state-backed attackers. As technology advances, cyber-attacks are becoming more sophisticated, severe, and frequent, posing significant financial repercussions for businesses and individuals alike.
Insurers are focusing on third-party risk management, demanding robust vendor agreements, and security audits to address these evolving cyber risks. They are also utilizing artificial intelligence for sophisticated risk assessment and fraud detection. However, artificial intelligence itself poses cybersecurity challenges due to biases and ethical concerns. The insurance industry must also navigate a complex and evolving regulatory landscape, with stricter data protection laws and increased scrutiny on cybersecurity disclosures.
While the cyber insurance market is expected to experience steady growth in the medium term, there is still a significant gap between economic losses and insured losses. Large companies account for the majority of premiums, while small and medium-sized enterprises bear most of their cyber risks on their own. Insurers need to develop innovative products, risk-adequate pricing, and robust risk modelling capabilities to close this gap and ensure the long-term insurability of cyber risks.
In conclusion, cyber risks are a growing concern for insurers due to the increasing reliance on technology, the evolving nature of cyber threats, and the potential impact on businesses and individuals. Insurers play a critical role in mitigating these risks and must continuously adapt their strategies to address the dynamic cyber risk landscape.

Risk pooling is fundamental to insurance
Risk pooling is a form of risk management that is fundamental to the concept of insurance. It involves multiple insurance companies coming together to form a single pool to protect themselves from catastrophic risks such as floods, earthquakes, or other natural disasters. By pooling risks, insurance companies can spread the financial impact of individual losses across the entire pool, reducing the burden on individual policyholders. This provides financial protection to policyholders in the event of unexpected losses.
The larger the risk pool, the more predictable and stable the premiums can be. This is because the costs of the less healthy or high-risk individuals are offset by the relatively lower costs of healthy or low-risk individuals. However, a large risk pool does not necessarily translate to lower premiums. The key factor influencing premiums is the average healthcare or medical costs of the enrollees included in the pool. If a risk pool attracts a disproportionate share of unhealthy individuals, premiums will be higher than they would be with a healthier group of enrollees.
Adverse selection, where an insurer attracts a disproportionate share of unhealthy individuals, can lead to a premium spiral. This occurs when higher premiums resulting from adverse selection cause healthier individuals to opt out of coverage, further increasing premiums. To avoid premium spirals, insurers aim to attract a broad base of healthy individuals, over whom the costs of sick individuals can be spread, keeping premiums affordable and stable for all members in the risk pool.
Risk pooling is also important for insurance companies to limit their total loss in the event of a disaster. By pooling risks with other insurance companies, a primary insurance company can insure clients whose coverage would be too large for a single company to bear alone. This is known as reinsurance, and the claim amount is typically shared by all the insurance companies in the pool. Risk pooling thus enables insurance companies to operate more efficiently, provide coverage at reasonable rates, and safeguard themselves from excessive losses.

Frequently asked questions
Pure risk embodies most or all of the main elements of insurable risk, including being "due to chance", definiteness and measurability, statistical predictability, lack of catastrophic exposure, random selection, and large loss exposure. Speculative risks, on the other hand, lack the core elements of insurability and are almost never insured. Examples include gambling and investing.
Insurance companies provide financial protection or reimbursement against losses resulting from accidents, injury, or property damage. They pool clients' risks to make payments more affordable for the insured.
Essential insurance policies include health insurance, auto insurance, business insurance, home insurance, and life insurance.
The premium for a policy is determined by the insurer's perception of the policyholder's risk for a claim. For example, if you own several expensive automobiles and have a history of reckless driving, you will likely pay a higher premium for an auto policy compared to someone with a single midrange sedan and a perfect driving record.
