Best’s Special Report: Big Year of Growth for Life/Annuity Sidecar-Like Activity in 2025

AM Best reports sidecar-like reserve activity rising to more than $90B in 2025 from $55B in 2023, driven by strong U.S. annuity sales. The ceded reserves largely cover liabilities for indexed and fixed annuities, suggesting increased structuring/liquidity support around growth in annuity products.

Analysis

This is a moat-expansion signal for the few platforms that can warehouse duration and source spread assets cheaply. The economic winner is not just the annuity writer; it is the capital intermediary that earns fees while offloading reserve intensity, which should keep valuation multiples firmer for insurers with embedded asset-management income. Smaller life carriers without a captive funding partner risk becoming volume takers: they can still grow, but at a higher capital cost and with less ROE leverage.

The second-order effect is tighter demand for long-duration, investment-grade and structured credit paper, which should support LQD/HYG-adjacent spreads, private credit origination, CLO warehouses, and any manager that can manufacture yield without owning too much balance-sheet risk. That demand is good until it isn’t: if credit spreads widen or defaults rise, the sidecar model can shift from capital relief to capital fragility within 1-3 quarters, especially if the underlying blocks are concentrated in spread-sensitive annuity liabilities.

Consensus is likely underpricing how procyclical this becomes if rates fall from here. Lower crediting rates can keep annuity sales elevated, but they also reduce spread cushion and make the system more dependent on benign credit and lapse behavior; that is a 6-18 month risk, not a day-one issue. The cleanest expression is to own the fee-income platforms and fade old-line insurers that need spread expansion to justify growth; if reserve transfer growth stalls or statutory capital ratios weaken, the thesis breaks quickly.

Key Decisions for Investors

• Long APO vs short PRU on a 1-3 month horizon: APO has the cleaner fee-income and insurance capital-arbitrage exposure; use a relative-value structure to isolate the sidecar theme. Falsify if APO’s fee-related earnings or ATH growth decelerate in the next print.
• Long KKR vs short LNC over 6-12 months: KKR should benefit from persistent demand for insurance-linked assets and capital-light growth, while LNC is more exposed to spread pressure and reserve volatility. Stop if LNC shows materially improving RBC/capital generation or KKR’s spread deployment slows.
• Watch BSAA for a pullback entry only if the next filing confirms recurring fee income and third-party capital deployment; otherwise treat it as a flow-driven story, not a durable compounder. Best entry would be on a post-news retrace rather than chasing the initial move.
• If credit markets stay calm, consider a modest long LQD / short HYG pair as an indirect expression of the reserve-bid for higher-quality spread assets; exit if CCC spreads widen sharply or defaults accelerate.
• Set an alert on 1Q/2Q annuity sales and reserve-ceding disclosures from major carriers; if growth inflects down for two consecutive quarters, rotate out of the theme because the market will likely re-rate the whole complex lower.
