The IUL boom is also a stress test. Most carriers haven't noticed yet.

Indexed universal life had a record year. New premium hit $4.5 billion in 2025, up 19% from the year before, and IUL now represents a quarter of total U.S. individual life premium. Forecasts call for continued double-digit growth, fueled by expanded distribution and a wave of new product launches. 

That's the story most of the industry is telling, but there's another story running underneath it that gets less attention.

Regulators have tightened IUL illustration rules for the third time in a decade, with a fourth cycle already under discussion. The NAIC's Life and Annuity Illustration Subgroup has shifted from rulemaking to inspecting carriers' actual illustration practices, conducting "building code" reviews of 13 carriers in 2025 alone. Class action litigation around IUL illustrations has intensified materially in recent years. And the operational complexity of writing, illustrating, servicing, and supporting IUL business is widening the gap between carriers with modern infrastructure and carriers still running systems built for a different generation of products.

Each of these is a story on its own. Together, they're something more interesting.

The product isn't the problem. The product is the test.

The real question the IUL boom is raising isn't about IUL at all. It's about whether carriers can operate in a continuously adaptive product environment, where regulatory requirements, product designs, distribution expectations, and consumer behavior all change faster than legacy infrastructure can absorb. Through that lens, modernization isn't primarily about cost reduction. It's about organizational responsiveness. Infrastructure determines strategic agility, and agility is now a competitive differentiator.

IUL happens to be the test case. Its combination of complexity, scale, and regulatory scrutiny is putting pressure on every part of a carrier's operating architecture at the same time. Carriers managing IUL on infrastructure designed when current regulations didn't exist yet are operating at a disadvantage and compounding risk over time.

The carriers that build adaptive capability now will write IUL profitably. Just as importantly, they'll be ready for whatever product cycle comes next. The carriers that don't will keep getting caught flat-footed by each new wave of change.

What's in the white paper

Our latest white paper examines this dynamic in detail. It covers:

• The five operational pressure points IUL puts on carrier infrastructure simultaneously
• The recent regulatory shift from rulemaking to active inspection, and what this signals about what's coming next
• What recent litigation and settlement activity is revealing about which carriers are exposed and why
• A diagnostic framework for assessing whether current infrastructure can support both today's IUL business and what comes next

It's a paper for leaders thinking about modernization not as a defensive cost but as a strategic capability.
