YRT Rate Increases: How Life Insurers Should Respond

Last reviewed: November 2026

YRT rate increases happen when a life reinsurer raises the yearly renewable term premium rates it charges on business already reinsured. Because YRT premiums are charged on the net amount at risk every year, even a modest increase cuts the cedent's margin across the whole in-force block.

The cedent's position depends almost entirely on the treaty wording, the mortality evidence and the realistic alternatives. A rate increase letter is a negotiation opening, not a final bill.

This guide is for chief actuaries, CFOs, heads of reinsurance and treaty managers at life insurers. It covers what the treaty allows, how to measure the impact, and which response fits which situation.

Key Takeaways

• YRT rate increases are only possible where the treaty allows them, so the guarantee clause is the starting point of any response.
• Common wordings guarantee rates for a period, cap them at valuation mortality, or require increases to apply to all similar business.
• The strongest evidence is the cedent's own actual-to-expected mortality on the reinsured block.
• Recapture removes the higher premium but brings mortality risk and capital need back onto the balance sheet.
• Arbitration panels have both upheld increases and given cedents a recapture alternative, so outcomes turn on wording.
• Under IFRS 17, the change flows through the contractual service margin of reinsurance held rather than hitting profit at once.

What Are YRT Rate Increases?

A YRT rate increase is a change to the premium rate scale a reinsurer applies to the net amount at risk on reinsured life policies. It usually applies to in-force business, which is why it matters so much.

Under yearly renewable term reinsurance, the cedent pays the reinsurer a premium each year based on the reinsured net amount at risk and the insured's attained age. The reinsurer pays its share of death claims.

The cedent keeps the savings element, reserves and policyholder relationship. The reinsurer takes the mortality risk on the ceded amount at risk.

If the reinsurer later concludes its rates were too low, it may try to raise them. The question is whether, how far and on what basis the treaty lets it do so.

Why Do Reinsurers Reprice In-Force YRT Business?

Reinsurers reprice when the business they hold is less profitable than priced. The commonly cited drivers are mortality, lapse and capital.

• Mortality worse than priced. Experience at older ages, higher face amounts or in specific underwriting classes comes in above the pricing assumption.
• Lapse and persistency. Pricing assumed lapses that did not happen, so more policies reach older ages and higher YRT rates than expected.
• Mortality improvement. Improvement assumed in pricing did not emerge at the expected pace.
• Capital and returns. Capital requirements or return targets changed after the business was written.

Not every driver gives a contractual right to reprice. A treaty that allows increases only for changes in anticipated mortality does not automatically allow increases driven by capital or return targets.

What Does the Treaty Actually Allow?

The YRT premium rate guarantee clause defines the reinsurer's right to increase rates, and it varies widely between treaties. Society of Actuaries research on life reinsurance treaty construction found language is not standardised.

That research describes several approaches, summarised below.

Publicly filed treaties show how these combine. One YRT agreement filed with the US Securities and Exchange Commission in 2021, between Nationwide entities and Hannover Life Reassurance Company of America, lets the reinsurer increase rates on in-force and new business on 90 days' notice.

That same agreement limits any rate guarantee to one year from inception and caps guaranteed rates at the greater of statutory minimum mortality and the attached rate schedule. It also lets the cedent immediately recapture affected business.

The lesson is simple. Read the premium clause together with the recapture, notice, dispute resolution and "entire agreement" clauses before replying to any letter.

What Have Courts and Arbitrators Said?

Published disputes show that YRT rate increase outcomes depend on wording, and that recapture is often the alternative remedy. They do not show a general rule for or against increases.

General Re Life v. Lincoln National

The YRT agreement let General Re raise premiums if the increase was based on a change in anticipated mortality, while Lincoln could recapture instead. An arbitration panel's 2015 award found General Re was entitled to increase premiums.

The later court dispute concerned the panel's clarification of how the award treated unearned premiums once the business was recaptured. The US Court of Appeals for the Second Circuit held in 2018 that the panel could clarify its ambiguous award.

General Re Life v. American General Life

In this YRT rate increase dispute, the arbitration panel ordered the cedent to pay increased rates, with an alternative allowing it to recapture. The cedent chose recapture.

In March 2024, the US District Court for the Southern District of New York confirmed the award. It also declined to seal the award, despite the parties' confidentiality agreement.

The lesson: arbitration does not reliably protect a cedent with weak wording. It also signals that confidentiality may not survive court proceedings to confirm an award.

How Much Does a YRT Rate Increase Cost?

The cost is the extra reinsurance premium, but the real question is how much margin it takes and whether the evidence supports it. The worked example below tests both.

Worked Example: A 20% Increase on a Term Block

The illustration is simplified, annual and pre-tax, in USD millions, on the cedent's pricing basis. It ignores discounting and investment income.

Block: term life with gross premium of 100 and expected gross claims of 60. The reinsured share of expected claims is 36, ceded on a YRT basis for a premium of 40.

A 20% increase on the YRT premium halves the block's margin. The recoveries do not change, because the increase changes the price, not the risk.

Now test whether the increase is justified. The table shows the reinsurer's margin on this block at different levels of the cedent's own actual-to-expected (A/E) mortality.

If the block runs at 100% A/E, the increase lifts the reinsurer's margin from 10% to 25%. That suggests the increase is driven by experience elsewhere, or by targets rather than this block's mortality.

If the block runs at 110% A/E, restoring a 10% margin needs a YRT premium of 44, which is a 10% increase. That puts the cedent's profit at 12, not 8.

The lesson for cedents: never respond to a rate letter without your own A/E on the reinsured block. The data turns a pricing demand into a negotiation about evidence.

What Are the Options When a Reinsurer Reprices?

The realistic options are to accept, negotiate, challenge, recapture and retain, or recapture and re-place. The right choice depends on wording, evidence and capital.

Using the worked example, the annual pre-tax profit under each option is shown below. The re-placement figure assumes another reinsurer quotes 42, or 5% above the old rate.

Recapture looks best on expected profit, but it brings 36 of expected claims and their volatility back onto the balance sheet. Whether 20 beats 12 depends on the capital required, its cost and your retention limits.

Where policyholder charges are non-guaranteed, some cedents consider passing costs through. That route carries its own regulatory, conduct and litigation risk and should be assessed separately.

Which Mistakes Weaken the Cedent's Position?

Seven mistakes repeatedly weaken cedents in YRT rate negotiations. Most are made years before the letter arrives.

How Should Life Insurers Prepare Before the Letter Arrives?

Preparation is the best defence, because the reinsurer will have done its analysis before writing. The data and questions below put the cedent on equal footing.

What Data Should the Cedent Hold?

Mortality data quality is often the weak point. We discuss it further in individual life reinsurance and mortality data.

Which Questions Should You Ask the Reinsurer?

• Which treaty clause gives the right to increase, and what evidence meets its conditions?
• Is the increase based on this block's experience, or on a wider portfolio?
• Does the increase apply to all similar YRT business, as the treaty may require?
• Is a phased or capped increase possible, linked to emerging experience?
• What recapture terms apply if the cedent elects to recapture?

How Do YRT Increases Affect Reserves, Capital and Reporting?

A rate increase changes the value of reinsurance held in every reporting basis, not just cash flow. The effect differs by framework.

IFRS 17

Under IFRS 17, reinsurance contracts held are measured separately from the underlying contracts. Higher expected future YRT premiums change the fulfilment cash flows, and changes relating to future service adjust the contractual service margin of the reinsurance held.

US Statutory and GAAP

Higher YRT premiums can affect the reserve credit and the cost of reinsurance recognised under statutory and US GAAP bases. Actuarial teams should model the effect alongside the cash cost before agreeing terms.

Solvency II and Similar Regimes

Future YRT premiums form part of the best estimate of recoverables. A rate increase reduces the net value of reinsurance and can raise the life underwriting risk the cedent effectively retains.

What Is the Market Context?

YRT rate increases have historically been infrequent, but they remain contentious. The Society of Actuaries research cited above describes premium guarantee and rate increase provisions as a long-running source of contention.

Treaty wording has shifted towards clearer guarantees and conditions over time. Older treaties written with weaker protection remain in force, and those are where repricing pressure tends to concentrate.

For cedents writing new business, the priority is wording that is clear, conditional and backed by a realistic recapture right. For in-force blocks, the priority is data that answers a rate letter quickly and credibly.

Checklist for Chief Actuaries and Heads of Reinsurance

Use this checklist to prepare every YRT treaty for a possible repricing.

• The premium guarantee clause for each treaty is summarised, with cap, conditions and notice periods
• Recapture rights are mapped by treaty, with deadlines and retention-limit effects
• Block-level A/E mortality is refreshed at least annually by treaty
• Lapse experience is compared with pricing assumptions for each block
• Current rate schedules and all amendments are held in one controlled record
• Options are modelled on profit, capital and IFRS 17 CSM before negotiation
• Any agreed increase is documented in a formal amendment, not an email
• New treaties include a consistency condition and a clear recapture right

Centralised reinsurance treaty management keeps premium rules, amendments and settlement calculations in one place. That makes the first response to a rate letter a matter of hours, not weeks.

Key Terms

Yearly renewable term (YRT) reinsurance: Reinsurance where the cedent pays an annual premium on the reinsured net amount at risk, based on attained age, and the reinsurer pays its share of death claims.

Net amount at risk (NAR): The death benefit minus the policy reserve or cash value, which is the amount the reinsurer actually covers.

Premium rate guarantee: The treaty clause that limits whether, how far and on what basis the reinsurer may change YRT rates.

Valuation mortality: The mortality table used for statutory reserving, often used as a cap on guaranteed YRT rates.

Actual-to-expected (A/E) mortality: Actual death claims divided by the claims expected on a stated basis. Values above 100% indicate worse-than-expected mortality.

Recapture: The cedent taking back previously reinsured business, ending the reinsurer's liability for it.

Consistency condition: A clause requiring any rate increase to apply to all of the reinsurer's similar YRT business, not just one cedent.

Contractual service margin (CSM): Under IFRS 17, the unearned profit or net cost in a group of contracts, including reinsurance contracts held.
