Why Life Insurance Needs Broader Adoption of RILA‑style Designs

By: Eric Sondergeld | 4/30/2026

For decades, life insurance and annuities have evolved in a kind of product “echo system.” Innovation often begins on the annuity side. A new annuity design gains traction, demonstrates consumer appeal, and proves economically viable. Then, a life insurance corollary eventually follows, usually years later, once carriers identify how to adapt the concept to a permanent policy .

This longstanding pattern has produced the product landscape we know today. But there is now one important evolution to note: while Registered Index Linked Annuities (RILAs) have surged, a fully mainstream life‑side equivalent has not yet taken root; though a few carriers have launched registered, buffered/floored life designs. History suggests broader adoption is likely and that there is a significant opportunity to scale such products.

Across all major product categories, the annuity product came first and the Universal life type product came later. In nearly every case, the delay wasn’t due to lack of demand, but because life insurance needed the right policy chassis to replicate the annuity’s risk/return mechanics. That became possible only once Universal life emerged in the early 1980s, providing flexible premiums, adjustable charges, and a transparent crediting methodology that could adapt to new ideas.

Here’s how the sequence unfolded:

1. Fixed Annuities → Fixed Universal Life

Fixed annuities long predated any flexible premium life insurance structure. Once UL was introduced, carriers could finally create the life insurance version: a flexible premium permanent policy with stable crediting and conservative accumulation.

2. Variable Annuities → Variable Universal Life (VUL)

Variable annuities had a major growth era before carriers were ready to translate fund-based investing onto the life chassis. Only later did VUL emerge, delivering market-based accumulation alongside a flexible death benefit.

3. Fixed Indexed Annuities (FIA) → Indexed Universal Life (IUL)

FIAs proved that consumers wanted market linked upside combined with downside protection. Not until years later and only after FIAs were well established did IUL appear and become the fastest growing permanent product in the industry.

In every case, the life equivalent lagged the annuity by many years, but eventually arrived, completing the product pair.

The Efficient Frontier: Three Pairs That Make Sense

Across these three product categories, the symmetry is clear. Each annuity has its corresponding version in the life insurance world:

The Middle is Emerging, But Not Mainstream

Registered index‑linked mechanics have begun to appear on the life side, primarily as indexed variable universal life (IVUL) offerings that blend index‑linked crediting with buffers/floors and traditional VUL subaccounts. Examples include Prudential FlexGuard® Life IVUL, which provides S&P 500-linked strategies with selectable buffers and floors alongside variable options, and Equitable’s Market Stabilizer Option® II on its VUL lineup, which adds multiple buffered segments tied to the S&P 500® Price Return Index.

This is not evidence that the historical innovation pattern has ended. If anything, it suggests the opposite: we are still in the familiar waiting period between a successful annuity innovation and the life insurance version that eventually follows.

The Evidence Behind Consumer Demand for a “RIVUL”

RILAs are the fastest growing annuity segment. LIMRA’s preliminary 2025 data show RILA sales up 20% to $79.6B, marking 11 consecutive years of growth; LIMRA projects RILAs to exceed $85B in 2026 and keep expanding through 2028. This sustained momentum signals strong appetite for “between indexed and variable” risk.

Indexed products now dominate annuity buyer preference. In 2025, RILAs + FIAs comprised 45% of all U.S. annuity sales, up from 24% a decade ago, clear evidence that consumers favor growth with guardrails over all-or-nothing equity exposure.

The implication is that buyers are voting with their dollars for calibrated risk, more upside than traditional indexed designs, less downside than fully variable. A Registered Index Linked Universal Life (RIVUL) would transplant this proven preference onto a permanent life chassis, filling the only remaining gap between IUL and VUL. Notably, life insurers have begun to transplant these calibrated‑risk mechanics into registered life products (e.g., IVUL with buffers/floors), validating the translatability of RILA concepts onto a life chassis, even if penetration is still early.

Why the Industry Should Expect and Want a RIVUL

1. RILAs proved demand for calibrated risk‑taking. Some clients want more upside than IUL can reliably offer, especially in today’s hedging‑constrained environment, but fewer swings than VUL. A RIVUL could deliver that blend. Early IVUL launches with buffers/floors support this appetite on the life side, but broader adoption and simpler positioning are needed.
2. Advisors like symmetry across product categories. Having parallel annuity and life product sets simplifies conversations, planning strategies, and client education. Today’s IVUL options move in that direction, but they’re not yet a ubiquitous “fourth pillar” alongside UL, IUL and VUL.
3. Life insurers need new accumulation tools. Cap compression in IUL and risk‑management challenges in VUL create space for a middle‑ground option, one that offers growth potential with guardrails.
4. There is genuine competitive white space. The carrier(s) that mainstream a RILA‑equivalent life product that is easy to position, broadly approved, and well supported in distribution, could see an early‑mover advantage akin to early FIA and IUL leaders.

Why It Hasn’t Happened Yet and Why It Still Will

We’re partway through the familiar lag. The industry has begun introducing registered, buffered/floored life designs (RIVUL), but compared with RILAs, today’s shelf space and advisor familiarity are still limited. The underlying forces that historically brought life‑side equivalents into existence are fully present today: strong consumer demand, clear advisor familiarity with buffers/floors, a proven annuity concept, and a flexible UL/VUL chassis capable of supporting the mechanics. There is no structural reason a RIVUL cannot scale.

Conclusion: The Opportunity Ahead

As this category develops, understanding how financial advisors perceive, position, and compare RIVUL to IUL, VUL, and RILAs will determine how quickly it scales. Through Greenwald Research’s Product Marketing Lab, built specifically for complex products like FIAs, RILAs, and IUL, we run in‑depth advisor interviews to pressure‑test product design, presentation, positioning, messaging, and training/resources needed. RIVUL is exactly the kind of nascent category where these insights de‑risk launch decisions and accelerate adoption.

Rather than a missing link, this is an emerging category in need of scale. A carrier bold enough to mainstream a registered, RILA‑style life product, making it easy to position, broadly approved, and well‑supported in distribution, could unlock a new era of controlled‑risk accumulation for consumers.
