U.S. insurers are taking a closer look at investment risk as portfolios increasingly include assets whose values are difficult to determine through traditional market pricing. The growing role of private credit, structured investments, mortgages and other less-liquid holdings is putting greater attention on so-called Level 3 assets, which rely heavily on models and other unobservable inputs for valuation.
The issue is becoming more important as insurers manage enormous investment portfolios while balancing two competing priorities: generating enough income to remain profitable and maintaining sufficient liquidity and capital to pay policyholder claims.
What Are Level 3 Assets?
Level 3 assets are investments for which market prices are not readily observable.
Instead of relying on an active market quotation, insurers may use valuation models that incorporate assumptions about expected cash flows, interest rates, credit quality and other factors.
That does not mean the investments are inherently risky or improperly valued.
But it does mean their valuations can be more difficult for outside investors and regulators to independently verify.
Why Insurers Own These Assets
Insurance companies collect premiums today to cover claims and other obligations that may arise years into the future.
That gives many insurers a long investment horizon.
Private credit, real estate, mortgage-related securities and other less-liquid investments can provide attractive yields and long-term cash flows.
For life insurers in particular, those characteristics can align with long-duration liabilities.
The Search for Investment Income
Insurers have historically relied heavily on bonds.
But changing interest-rate conditions and competition for investment returns have encouraged some companies to expand into private markets.
Higher-yielding private investments can help insurers generate additional investment income.
That income can support profitability and, in some cases, help offset pressure from insurance underwriting.
The Valuation Challenge
The main concern surrounding Level 3 assets is not simply how much insurers own.
It is how accurately those assets can be valued during changing market conditions.
When markets are functioning normally, valuation models can provide reasonable estimates.
But if economic conditions deteriorate, assumptions can change quickly.
An asset that appears stable on a balance sheet may become harder to sell at its reported value.
Liquidity Is a Key Issue
Insurance companies must maintain enough liquid assets to meet claims.
For a property insurer, a major hurricane or wildfire can create a sudden need for cash.
For life insurers, liquidity requirements can be driven by policyholder behavior and other obligations.
That means companies cannot treat every investment as equally accessible.
Private Credit Is Under the Microscope
Private credit has become one of the most closely watched areas.
The market allows non-bank lenders to provide financing directly to companies.
Insurers can gain exposure through loans, funds and other structures.
The attraction is clear: private loans can offer higher yields than some traditional fixed-income securities.
But private-credit markets generally provide less frequent price discovery than public bond markets.
Credit Risk Can Change Quickly
A private loan may appear relatively safe when a borrower is performing well.
If economic conditions weaken, however, the borrower’s ability to repay could deteriorate.
Because private assets are less frequently traded, problems may not immediately appear through market prices.
That places greater importance on insurers’ internal credit analysis.
Structured Investments Add Complexity
Insurers also invest in structured products that can combine multiple types of underlying exposures.
These investments can offer diversification or enhanced returns.
But their risk can be difficult to understand without detailed analysis of the underlying assets.
That makes transparency especially important.
Regulators Want Greater Visibility
Insurance regulators have been working to improve the information available about insurer investments.
The National Association of Insurance Commissioners has developed reporting and capital frameworks covering various investment categories.
The objective is to ensure that insurers hold adequate capital against the risks associated with their portfolios.
Why Capital Requirements Matter
Capital provides a financial cushion.
If investments lose value or claims rise unexpectedly, insurers with strong capital positions have greater ability to absorb the shock.
Regulators therefore consider both the composition of an insurer’s investments and the capital supporting those investments.
Level 3 Does Not Mean “Bad”
It is important to distinguish valuation complexity from investment quality.
An asset classified as Level 3 is not automatically unsafe.
Some private investments can generate predictable cash flows and perform well over long periods.
The concern is that the valuation process involves more assumptions than publicly traded securities.
Market Stress Is the Real Test
The biggest question may be what happens during a severe downturn.
If an insurer needs to raise cash quickly, it may discover that certain investments cannot be sold easily.
A sale under pressure could occur below the value recorded on financial statements.
That could create additional losses.
Interest Rates Remain Important
Interest rates affect nearly every part of an insurer’s investment portfolio.
When rates rise, the market value of many existing bonds falls.
At the same time, insurers can reinvest new money at higher yields.
Private investments also respond to changing financing conditions.
That makes interest-rate management essential.
Life Insurers Have Long-Term Advantages
Life insurers can sometimes hold illiquid assets for longer because their liabilities may extend over many years.
That reduces the need to sell assets immediately.
But it does not eliminate risk.
Policyholder behavior, economic conditions and changes in interest rates can alter liquidity needs.
Property Insurers Need More Flexibility
Property-and-casualty insurers can face sudden claims after catastrophic events.
That makes liquid assets particularly valuable.
An insurer with a large portfolio of difficult-to-sell investments could face greater challenges after a major disaster.
Investment Managers Also Matter
Many insurers rely on outside investment managers.
These managers may specialize in private credit, real estate or other alternative assets.
The insurer remains responsible for managing its overall risk, however.
Strong oversight of external managers is therefore critical.
Concentration Can Increase Vulnerability
Another concern is concentration.
If several insurers hold large amounts of similar private assets, a downturn in one market could affect multiple companies at the same time.
That creates potential risks beyond individual insurers.
Regulators therefore monitor broader industry exposures.
The Insurance Industry Is Becoming More Complex
Insurance companies were traditionally viewed primarily as underwriting businesses.
Today, they are also major participants in global financial markets.
Investment income can be an important component of insurer profitability.
That means financial-market developments can increasingly affect the insurance sector.
Consumers May Feel the Effects
Investment performance can influence insurers’ overall financial strength.
Strong returns can support capital and profitability.
Large losses can create pressure that eventually affects pricing strategies.
For policyholders, the investment portfolio is therefore not an abstract financial issue.
It is part of the insurer’s ability to remain financially stable.
Investors Want Better Disclosure
Shareholders are increasingly interested in understanding how insurers generate investment income.
They want to know:
- How much is invested in private markets?
- How much is classified as Level 3?
- How are those assets valued?
- What are the underlying credit risks?
- How quickly can assets be liquidated?
- How much capital supports those investments?
Greater disclosure can make those questions easier to answer.
Insurers Face a Delicate Balance
The industry cannot simply avoid every complex investment.
Doing so could limit investment opportunities and reduce portfolio diversification.
But insurers also cannot pursue higher yields without considering liquidity and credit risk.
The challenge is finding the appropriate balance.
The Regulatory Focus Is Likely to Continue
As private markets grow, regulators are likely to continue examining insurer exposure.
The objective will be to ensure that investment strategies do not undermine the financial protection insurers are expected to provide.
That means capital requirements, valuation practices and risk-management standards could remain areas of significant attention.
A Broader Financial-Market Issue
The rise of Level 3 assets among insurers reflects a broader shift across financial markets.
Banks, pension funds, asset managers and other institutions have also increased exposure to private investments.
The difference for insurers is that they manage money tied to policyholder obligations.
That creates an additional layer of responsibility.
What Comes Next
The insurance industry is likely to continue using private and complex investments because they can provide attractive long-term opportunities.
But the focus is increasingly moving toward how those assets behave during stress, not simply how much income they generate during normal markets.
Insurers that maintain strong liquidity, diversified portfolios and disciplined valuation processes could be better positioned when conditions change.
The Bottom Line
The growth of Level 3 assets in insurance portfolios does not automatically signal an impending crisis.
It does, however, highlight a changing risk landscape.
As insurers move deeper into private credit and other complex markets, regulators and investors will need greater visibility into valuations, liquidity and underlying credit quality.
For insurers, the objective remains straightforward but difficult:
Generate enough investment income to remain competitive without taking risks that could weaken their ability to protect policyholders.
That balance could become one of the industry’s most important financial challenges in the years ahead.
