When Structure Fails the Strategy: The Launch of ILS and the Risks of Going to Market Without an LMM

Brookmont Capital Management made headlines with the launch of the Brookmont Catastrophic Bond ETF

, the first U.S.-listed ETF to provide direct exposure to catastrophe bonds. Touted as a diversifying, income-generating product uncorrelated to traditional markets, ILS gives investors access to a traditionally institutional-only asset class via a transparent ETF wrapper.

However, its debut raises critical questions about product fit and market support, as the fund began trading without a Lead Market Maker (LMM) and experienced a trading range from $20.06 to $22.76 on day one—an 11.8% swing, with total volume of 150,470 shares traded.

Catastrophe bonds ("Cat bonds") are issued by insurers and reinsurers to transfer the financial risk of natural disasters. They offer attractive, floating-rate yields and relatively low correlation to equities or fixed income.

But Cat bonds are inherently complex: they are privately structured, event-driven instruments whose valuations depend on probabilistic models and insurance-specific risk parameters. These complexities make the role of ETF capital markets infrastructure—especially liquidity support—all the more important.

One of the most overlooked components of a successful ETF launch is the selection and engagement of a Lead Market Maker. An LMM plays a critical role in establishing consistent and tight two-sided markets, quoting at competitive spreads, and helping to ensure that the ETF trades in line with its underlying Net Asset Value (NAV). Without an LMM, ETFs can suffer from wide bid/ask spreads, thin volumes, and dislocated pricing—as was the case with ILS.

In this case, it appears that Brookmont sought out an LMM, but none were willing to take on the role—likely due to the inherent complexity and illiquidity of the underlying cat bond market. The underlying market itself is not particularly liquid, which may have discouraged market makers from stepping in.

That alone should have served as a clear warning sign. That fact alone raises a deeper question: if no market maker is willing to support the product at launch, does that say more about the readiness of the ETF ecosystem—or more about the product itself?

It also prompts an important industry discussion: in certain cases, should issuers be allowed to compensate market makers to ensure tighter spreads and more stable price discovery early on? While current rules do not permit direct payment, it’s widely understood that compensation often occurs indirectly through broader business relationships.

Perhaps it’s time for the industry to consider a more transparent and structured approach. As more complex or less liquid strategies come to market, formalizing this discussion could help improve trading quality and investor outcomes.

While such arrangements may not be necessary for broad, liquid exposures, niche ETFs might benefit from additional incentives to help establish trust and tradability. Additionally, one would think that a capital markets expert within the firm would have warned against launching without this critical infrastructure in place. The absence of such internal risk flagging is troubling—and underscores how risky this decision was for all investors involved.

In fact, the nature of the product and its trading behavior may suggest it would be more appropriately structured as a Qualified Institutional Buyer (QIB)-only product rather than a retail ETF.

While it’s tempting to view a compelling narrative—such as climate resilience or uncorrelated yield potential—as enough to support a successful ETF launch, structure matters. For niche strategies like ILS, a solid market making foundation is not just helpful—it’s essential. The absence of an LMM on launch day signals a missed opportunity to build early investor confidence and enable proper price discovery.

This launch should serve as a reminder that the ETF wrapper is not magic. Products that rely on less-liquid, complex, or opaque underlying exposures require an even greater emphasis on capital markets planning. That includes thoughtful coordination with authorized participants, active engagement with market makers, and proactive investor education.

ILS may very well succeed in time. The strategy is sound, the demand for alternative income is real, and catastrophe bonds offer genuine diversification benefits. But to gain long-term traction, the ETF must inspire trust in its ability to trade efficiently and accurately. In ETFs, structure and execution are just as important as innovation.
