Disintermediation Risk: Insurance Surrenders When Interest Rates Rise

What is disintermediation risk?

Disintermediation risk is the risk that policyholders withdraw or surrender money from interest-sensitive insurance and annuity contracts when competing market rates become more attractive.

For insurers, a rapid rise in rates can create a difficult combination:

1higher outside yields
2-> greater incentive to surrender
3-> insurer may need cash sooner than expected
4-> existing fixed-income assets may be below market value

If the insurer must sell those assets to fund withdrawals, unrealized losses can become realized losses.

Why investors care

Many life insurers and annuity writers fund long-dated investments with policyholder balances that can be withdrawn before the supporting assets mature.

The expected economics depend partly on how long policyholders keep their contracts.

When behavior changes quickly, the insurer can face:

• higher surrender and withdrawal outflows;
• asset sales at unfavorable prices;
• reduced investment spread;
• pressure to raise credited rates;
• greater liquidity needs; and
• changes in statutory capital or realized gains and losses.

Disintermediation is therefore both a policyholder-behavior risk and an Asset-Liability Management risk.

A simplified example

Suppose an insurer has $10 billion of fixed annuity balances earning a 3% credited rate. The supporting bond portfolio was purchased when market yields were lower than they are today.

If comparable new products begin crediting 5%, some existing policyholders may surrender and reinvest elsewhere.

If $1 billion leaves faster than the insurer expected, it may need to fund those payments from cash, maturing investments, borrowing, or asset sales.

The economic outcome depends on the available liquidity and the market value of assets sold.

A high surrender rate does not automatically mean a solvency problem, but it can make an existing interest-rate mismatch more expensive.

Surrender charges can reduce the incentive to leave

Many contracts impose surrender charges during early policy years.

A policyholder comparing alternatives should consider the value lost by surrendering, not only the headline rate available on a new product.

That friction can reduce disintermediation risk.

It does not eliminate it. Charges may decline over time, contracts can have free-withdrawal provisions, and a sufficiently large rate advantage can still motivate exits.

Market value adjustments can shift part of the risk

Some contracts contain a Market Value Adjustment that changes the amount received on an early withdrawal based on interest-rate conditions.

When rates have risen, a negative adjustment can reduce the amount paid to the exiting policyholder and help align the withdrawal value with the economics of the assets supporting the contract.

That can mitigate disintermediation risk, but the exact protection depends on the contract formula and which transactions are covered.

Crediting-rate flexibility matters

An insurer may also respond to rising market rates by increasing the rate credited to existing contracts.

That can improve retention, but it can reduce the insurer's Net Investment Spread if supporting asset yields do not rise as quickly.

Guaranteed minimum rates, contractual reset schedules, competitive pressure, and portfolio turnover all affect how much flexibility the insurer has.

Disintermediation risk is not credit risk

The issue is not that the bonds in the portfolio necessarily defaulted.

A high-quality bond can still trade below par after interest rates rise. If policyholder outflows force the insurer to sell before maturity, the insurer can realize a loss even without a credit impairment.

This distinction matters when reading an insurer's unrealized-loss disclosures.

A practical investor workflow

When analyzing disintermediation risk:

1. Identify products with surrenderable general-account balances.
2. Review surrender-charge schedules and free-withdrawal provisions.
3. Identify market-value adjustment features.
4. Compare current credited rates with competing market rates.
5. Review guaranteed minimum rates and reset flexibility.
6. Examine recent surrender, lapse, and withdrawal trends.
7. Compare liquid resources with plausible outflow scenarios.
8. Review unrealized losses on assets that might need to be sold.
9. Connect surrender behavior with duration mismatch and investment spread.
10. Avoid treating one quarter of elevated surrenders as a complete measure of long-term franchise quality.
