U.S. firms accelerate de‑risking deals with bulk annuities; rating agencies warn on concentrated longevity exposures

By [Staff Writer] — Feb. 6, 2026

Who: Major life insurers, reinsurers and new entrants in the annuity and reinsurance markets. What: A sharp acceleration of pension de‑risking through bulk purchase annuities (BPAs), coinsurance and funded reinsurance — accompanied by warnings from regulators and credit analysts about concentrated longevity exposures. When: activity and warnings have intensified across 2024–2026, with record reinsurance cessions reported in Q3 2025 and fresh deal activity and acquisitions into January 2026. Where: global flows are centered on the United Kingdom, the United States and Canada, with cross‑border reinsurance and offshore sidecars prominent. Why: improved pension funding, higher yields, insurers’ search for long‑duration liabilities to match assets and strong demand by corporate sponsors to remove pension volatility are driving deals — but rating agencies and regulators say the speed and concentration of exposures could create counterparty and liquidity risks.

Lead
U.S. and other developed‑market insurers have stepped up purchases of bulk annuities and deployed a growing array of reinsurance and asset‑intensive capital solutions to take on defined‑benefit pension liabilities, but regulators and rating analysts are flagging rising concentrations of longevity exposures — particularly where risk is reinsured offshore or aggregated in a small number of reinsurers and funded structures that hold illiquid assets. The market’s expansion has produced record ceded premiums and heavier reliance on coinsurance and funded reinsurance arrangements, prompting warnings from the United Kingdom’s Prudential Regulation Authority and intensified market‑intelligence scrutiny.

What’s happening and why it matters
Bulk annuities and pension risk transfer transactions — buy‑ins, buy‑outs and longevity swaps — continued to grow in scale through 2024 and 2025. Insurer research and industry monitors show the U.S. pension risk transfer market recorded about $51.8 billion of transactions in 2024; L&G’s 2025 Global PRT Monitor predicts multi‑year opportunity measured in hundreds of billions of dollars across the UK, U.S. and Canada. Insurers are attracted by the opportunity to write long‑duration, predictable liabilities that can be matched with higher‑yielding private assets and to win new business while pension sponsors seek to eliminate balance‑sheet volatility.

At the same time, the U.S. life industry’s use of reinsurance to shed blocks of life and annuity business has reached unprecedented levels: S&P Global Market Intelligence reported that record ceded premiums in Q3 2025 totaled roughly $194 billion, driven by large cohort transactions — including a transaction that shifted more than $45 billion in separate‑account liabilities in a single deal. Those transactions reflect both traditional coinsurance and more complex structures such as modified coinsurance (modco), quota shares, and funded reinsurance or sidecars sponsored by asset managers and alternative capital providers.

How insurers are executing de‑risking
Deal mechanics vary:

• Buy‑ins and buy‑outs: An insurer takes full responsibility for paying pensioner benefits (buy‑out eliminates the sponsor’s plan). These remain core transactions in mature markets such as the UK and are growing in the U.S. as trustees and sponsors seek finality. L&G and specialist BPA writers have invested in origination pipelines and streamlined propositions to capture both large and sub‑£100 million deals. (group.legalandgeneral.com)

• Reinsurance (coinsurance, modco, quota shares): Cedants transfer blocks of in‑force or new‑business annuity liabilities to reinsurers, either for capital relief or to reduce reserving and underwriting risk. Modco arrangements move assets and liabilities together in ways that can spike ceded premiums on statutory statements. S&P’s Q3 2025 analysis shows several single‑quarter spikes tied to major coinsurance/modco deals. (spglobal.com)

• Funded reinsurance and sidecars: Reinsurers or investor vehicles provide capital to assume longevity and other life risks; these counterparties often invest in private credit, infrastructure, or other illiquid assets. New entrant strategies — including acquisitions of established reinsurance platforms — have accelerated. Assured Guaranty’s January 21, 2026, acquisition of Bermuda‑domiciled Warwick Re (renamed Assured Life Reinsurance Ltd.) exemplifies strategic moves by non‑traditional players into annuity reinsurance and PRT segments.

Market drivers: funding, yields, capital and distribution
Several structural factors explain the push:

• Pension funding improved in many jurisdictions after gilt and Treasury yield moves, creating windows for sponsors to transact. L&G and others report historic highs in scheme funding in parts of the UK and robust U.S. appetite for de‑risking. (group.legalandgeneral.com)

• Higher yields and demand for long‑duration liabilities make annuities economically attractive to asset‑intensive reinsurers and insurers seeking to lock in spreads on private credit and infrastructure exposures. Rating‑agency commentary and market analysis show many insurers have materially increased allocations to private credit and other alternative income strategies. (wsj.com)

• New capital providers and private markets participants have created capacity and pricing competition: private equity‑sponsored platforms, asset managers, and financial guarantors are expanding into life and annuity reinsurance, sometimes buying platforms or backing sidecars that can underwrite large blocks quickly. The Assured Guaranty/Wa rwick Re deal in January 2026 is one recent example. (insurtech.me)

Regulators and rating analysts flag concentration and counterparty risks
As insurers and new entrants scale longevity business, rating agencies and prudential regulators have raised concerns about concentration and the end‑to‑end resilience of funded reinsurance arrangements.

The U.K. Prudential Regulation Authority (PRA) and senior Bank of England officials have repeatedly cautioned insurers not to overextend. Charlotte Gerken, executive director for insurance supervision at the Bank of England, warned in April 2023 that “as deals become larger and increasingly focused on buy‑outs of complete schemes, we observe BPA writers expanding their risk appetite, sometimes outside their current core expertise. Insurers may be tempted to stretch their capabilities in the short term before leaner years arrive,” and stressed insurers should consider exposures to counterparty concentration, recapture risk and the wider liquidity implications for the financial system. The PRA has signaled it will examine the sector’s funded reinsurance exposures in supervisory work. (researchgate.net)

S&P Global Market Intelligence’s reporting on Q3 2025 ceded premiums — and market commentary from other analysts — highlights how a small number of very large deals can distort statutory metrics and concentrate risk into a handful of reinsurers or capital vehicles. S&P analysts noted the third quarter’s spike reflected several previously announced block reinsurance transactions and that the industry’s ceded‑to‑gross‑premiums ratios reached one of the highest levels this century. Concentration in a small number of counterparties raises the specter of “mass recapture” or stressed collateral calls if a reinsurer’s asset mix underperforms or a reinsurer were to face a solvency shock. (spglobal.com)

Moody’s and other credit analysts have also warned about insurers’ growing exposure to private credit and illiquid investments — assets often held by funded reinsurers and sidecars underpinning longevity deals. One market summary noted that U.S. life insurers’ holdings of private credit ballooned to hundreds of billions of dollars and that a small group of insurers account for a disproportionate share of that exposure, heightening sectoral concentration risk. Rating agencies say this increases the importance of robust counterparty due diligence and stress testing. (wsj.com)

Transaction examples and the mechanics that matter
Large 2025 transactions illustrate both market scale and the structural questions at stake. S&P’s review of Q3 2025 singled out an Aug. 1, 2025, arrangement involving the Apollo‑backed Venerable platform in a transaction Corebridge characterized as “transformative,” which contributed materially to American General Life Insurance Co.’s reporting of $51.79 billion in ceded premiums that quarter. The magnitude of those cessions — and the use of modco and retrocession in subsequent chain transactions — underscores how single deals can create concentrated longevity risk pockets in new or offshore reinsurers. (spglobal.com)

Industry response and risk management
Insurers and reinsurers say they are aware of the risks and are adapting. Some firms are:

• Strengthening counterparty selection and collateral agreements for funded reinsurance.
• Increasing scenario testing and governance for longevity assumptions and portfolio illiquidity.
• Using pooled longevity reinsurance arrangements and retrocession strategies to distribute risk.
• Deploying capital carefully: some insurers report targeted capital deployment to scale BPA writing, while noting longevity reinsurance use may vary by transaction. M&G said it wrote £1.5 billion of BPAs in 2025 and emphasized a selective approach to longevity reinsurance, noting none of its 2025 transactions used it though it remained a potential management action. (mandg.com)

Even so, rating analysts warn that new entrants and private capital structures can be harder for cedants and regulators to monitor. Market intelligence points to an expanding set of players — traditional reinsurers, asset managers, private equity platforms, and guarantors — that provide capacity in different forms and jurisdictions, complicating oversight. Assured Guaranty’s acquisition of Warwick Re — which created an AA‑supported annuity reinsurer — demonstrates how non‑traditional entrants can offer differentiated, credit‑enhanced capacity that some cedants find attractive, but it also alters counterparty concentration dynamics. (insurtech.me)

Potential vulnerabilities
Analysts identify several key vulnerabilities that warrant oversight and careful management:

• Counterparty concentration: If a small set of reinsurers, sidecars or funded vehicles assume a large share of longevity risk, the failure or distress of any one could require expensive recapture or collateral calls. Regulators have signalled focused supervisory work on these exposures. (researchgate.net)

• Asset‑liability mismatch within funded reinsurers: Many funded reinsurance vehicles invest in private credit, infrastructure and other illiquid holdings. Under stressed conditions, these assets may be slow to liquidate or may fall in value, creating pressure on collateral and credit support structures. Moody’s and other analysts have flagged insurers’ increased use of private credit as a credit‑and‑liquidity consideration. (wsj.com)

• Regulatory arbitrage and cross‑border complexity: Offshore reinsurers domiciled in lower‑regulation jurisdictions can provide capital relief but complicate host‑regulator oversight of policyholder outcomes in cedants’ home markets. The PRA has warned about “offshored counterparty concentration risk” and the sectoral implications. (researchgate.net)

What rating agencies may do
While rating agencies have not issued a uniform sector‑wide downgrade, they have signalled heightened analytic focus: they are incorporating firms’ reinsurance counterparty concentration, funded reinsurance reliance, and asset liquidity into credit assessments and stress testing. That scrutiny can influence insurers’ economic capital management and the pricing and availability of BPA and reinsurance capacity. Market watchers expect ratings and outlooks to reflect both the immediate balance‑sheet effects of large cessions and the governance controls insurers apply to concentration, collateral, and counterparty credit. (spglobal.com)

Outlook and market implications
Most industry participants and advisers expect continued growth in pension de‑risking over the next five to 10 years as demographic pressures and sponsor appetite persist. L&G’s Global PRT Monitor projects a multi‑hundred‑billion‑pound opportunity over the coming decade, and specialist BPA writers such as M&G say they plan to scale annual sales materially. But sustained growth will depend on careful management of concentration and liquidity, regulatory responses, and the evolving ecosystem of reinsurers and capital providers.

Voices from the market
“Through the disciplined execution of our corporate pension strategy during 2025, we have rapidly scaled our position as a trusted partner for UK pension funds,” Kerrigan Procter, M&G’s managing director for corporate pension solutions, said in a Jan. 21, 2026, statement about the firm’s £1.5 billion BPA volume that year, noting M&G’s selective approach to longevity reinsurance. (mandg.com)

Regulators have been more cautionary. “Insurers may be tempted to stretch their capabilities in the short term before leaner years arrive,” Charlotte Gerken of the Bank of England said in April 2023, urging firms to consider reinsurer resilience, recapture risk and the liquidity consequences of large, concentrated positions. The PRA has followed with supervisory letters and signalled stress work on funded reinsurance exposures. (researchgate.net)

Concluding assessment
The bulk annuity and pension risk transfer market has matured into a global industry that now draws traditional life insurers, specialist reinsurers, private capital and structured‑finance players. That competition benefits pension sponsors and can reduce sponsor‑balance‑sheet risk, but it concentrates longevity exposures into a smaller and more complex constellation of counterparties and funded structures. Regulators and rating analysts have correctly emphasised that careful due diligence, robust collateral and recapture terms, stress‑testing of illiquid asset holdings, and prudent limits on single‑counterparty exposures will determine whether the boom in de‑risking delivers stable outcomes for policyholders and the wider financial system.
