Insurance Curator Insurers accelerate hedging and longevity-portfolio adjustments to protect capital ratios from repair and medical cost escalation
By [Staff Writer]
Who: Major life and health insurers, pension buy‑out providers, reinsurers and regulators. What: A broad, cross‑market push to expand longevity hedges, reinsurance and asset‑liability hedging while reshaping portfolios to defend solvency and regulatory capital ratios. When: Intensifying through 2024–2025 and continuing into 2026. Where: Markets across the UK, continental Europe, North America and Asia‑Pacific. Why: Rising claims and medical‑cost inflation — and the attendant risk to reserve adequacy and solvency metrics — have prompted insurers to accelerate hedging, transfer blocks of annuity and pension longevity risk, and adjust investment mixes to protect capital positions.

LONDON — Facing an unwelcome cocktail of accelerating medical‑cost inflation and persistent longevity improvements that increase future annuity liabilities, insurers in advanced economies have moved from planning to action: buying reinsurance and index‑linked longevity protection, stepping up longevity swaps and buy‑outs, raising hedge ratios on interest‑rate and inflation exposures, and rebalancing portfolios toward private, long‑duration assets and third‑party capital solutions to shore up solvency metrics. Executives and regulators say the moves are tactical responses to protect capital ratios and ensure the industry can absorb claim‑cost shocks without undermining policyholder guarantees.

What insurers are doing — and why it matters
Insurers’ actions fall into three linked categories: liability hedging (longevity risk transfer, buy‑ins/buy‑outs), market‑risk hedging (interest‑rate, inflation and duration matching), and capital‑management innovations (reinsurance sidecars, third‑party capital and portfolio repositioning). These moves are meant to lower the volatility of regulatory and economic capital measures such as Solvency II coverage ratios in Europe, statutory risk‑based capital (RBC) metrics in the United States, and the new international Insurance Capital Standard (ICS) for globally active groups. Regulators have signalled they expect firms to manage these exposures proactively. (reinsurancene.ws)
Longevity transfers have been a particularly visible lever. Large deals — including multi‑billion euro blocks reinsured to global reinsurers and insurers — deliver an immediate capital uplift by replacing uncertain, long‑dated liabilities with ceded risk. NN Group’s multi‑billion euro transfers of Dutch annuity liabilities in recent years, for example, were explicitly sold as capital‑strengthening moves; NN’s chief executive said the deals provided an “upfront capital benefit” and strengthened Solvency II ratios. Industry consultants say similar structures are now being placed at scale across the UK, Netherlands and other markets. (reinsurancene.ws)
“Insurers are navigating the environment with discipline,” BlackRock’s report on insurers’ investment views said, adding that capital‑management tools such as reinsurance sidecars and third‑party capital are being prioritized by a majority of surveyed firms. “Insurers are sophisticated allocators across public and private markets,” BlackRock’s Charles Hatami told the survey in October 2025.

Medical‑cost trends pushing claims higher
The hedging surge is being driven in part by sharply rising medical and pharmaceutical costs that are raising claim severities in health, group benefits, auto‑bodily‑injury and workers’ compensation lines.
Aon’s 2026 medical‑trend forecast projected a roughly 9.5 percent rise in U.S. employer health‑care costs for 2026 — part of a multi‑year pattern of elevated medical inflation that insurers must reflect in reserves and pricing. Aon executives warned in public comments that specialty drugs, new therapies and heightened demand for GLP‑1 class medicines (widely used for diabetes and increasingly for weight management) are notable drivers of the surge. U.S. health‑plan managers and life carriers with medical cost exposures have flagged the trend as materially affecting reserve adequacy and medical‑loss ratios. (prnewswire.com)
UnitedHealth Group, which operates large medical benefits businesses, said its adjusted medical care ratio rose year‑over‑year in 2025, reflecting “accelerating medical cost trends” among other factors — a concrete example of how medical inflation is moving through insurer financial statements. For insurers that underwrite stop‑loss, group medical or cover bodily‑injury claims in P&C lines, faster cost inflation translates directly into higher claim severities and, absent countervailing rate increases or reinsurance, weaker capital cushions.

Hedging and reinsurance: the mechanics and market capacity
Insurers are using several instruments to reduce liability variability and protect capital ratios:
-
Longevity swaps and reinsurance: Direct transfers of longevity exposure to reinsurers or specialist longevity investors remain the most expedient way to reduce Solvency II capital charges tied to longevity assumptions. Large European insurers and a growing set of overseas reinsurers and institutional investors have been active buyers and sellers of these structures. NN Group’s €13 billion transfers to Prudential and Swiss Re are a widely cited example of a capital‑protecting longevity reinsurance program. (reinsurancene.ws)
-
Buy‑ins and bulk annuities: Pension schemes transferring liabilities to life insurers (buy‑ins/buy‑outs) reduce sponsors’ and insurers’ exposure, but they also expand insurers’ annuity books — a dynamic that has forced insurers to scale hedging and capital plans to accommodate new Bitcoin‑sized blocks of guaranteed liabilities. UK de‑risking volumes surged in recent years, with more schemes approaching insurers for quotations and record transaction volumes, prompting insurers to be more selective while expanding operational capacity.

-
Derivatives and ALM hedges: Insurers have raised swap and swaption usage to lock in duration, hedge interest‑rate and inflation mismatch, and protect regulatory surplus against market moves. Market makers and large‑scale asset managers report rising demand for these instruments, and insurers are increasingly using dynamic hedging programs that aim to protect both economic earnings and regulatory capital positions. Industry commentary notes that more precise hedging is required when insurers are managing Solvency‑level sensitivities as well as IFRS and statutory results. (wtwco.com)

Third‑party capital, sidecars and reinsurance markets: To reduce balance‑sheet capital consumption and access capacity, insurers are using reinsurance sidecars, institutional reinsurance investors and syndicated longevity capacity. BlackRock’s 2025 insurance survey found two‑thirds of respondents aiming to use reinsurance sidecars and half targeting more third‑party capital over the following 12 months. At the same time, growing pools of alternative reinsurance capital and a “capital overhang” in parts of the reinsurance market have pushed pricing lower for some reinsurers, increasing the supply of capacity but affecting returns.

Regulatory and accounting context
Regulatory changes and international convergence on capital standards are shaping how insurers hedge. The IAIS’s Insurance Capital Standard (ICS) and ongoing jurisdictional implementations of Solvency regimes mean group capital outcomes are under closer scrutiny; supervisors expect proactive management of structural risks and may require higher quality capital or stronger liquidity planning for globally active groups. EIOPA’s Financial Stability Report and national supervisors have urged vigilance about market, geopolitical and macroeconomic risks that could stress insurers’ capital positions. Those signals, coupled with public stress‑testing and enhanced supervisory expectations, have pushed executive teams to be more conservative and explicit about hedging to preserve solvency buffers.

“In 2025 we’ve seen supervisors widen the scope of what they expect from insurers,” said a banking‑and‑insurer adviser summarizing regulatory shifts. “That raises the bar on capital planning and makes hedging and reinsurance more than an optional risk‑transfer tool — it’s central to capital management.” (Source: adviser interviews and industry reports.)

Concrete results and company examples
Insurers that acted early on longevity and market hedges report measurable capital and solvency benefits. NN Group said its 2023 longevity transfers would improve group Solvency II ratios by roughly eight percentage points (and NN Life’s ratio by a larger amount), enabling the company to free capital for operations while limiting impact on operating generation. David Knibbe, NN Group’s chief executive, said the transactions were “very attractive” economically and underscored active balance‑sheet management. (reinsurancene.ws)
In the UK bulk‑annuity market, specialist life carriers such as Rothesay, Legal & General and others have increased hedging rigor when writing new mandates; market analysts note Rothesay reported hedging around 90 percent of longevity risk on its liabilities, illustrating how far some firms go to neutralize longevity exposure before running new business. Rating agencies and market observers increasingly benchmark firms on hedging effectiveness as part of capitalization assessments. (cbinsights.com)
Investment shifts and portfolio implications
To match duration and reduce sensitivity of surplus to market moves, life insurers have been shifting a portion of portfolios into long‑dated, high‑quality fixed income and private assets — private credit and infrastructure in particular — that better match annuity cash flows and offer yield premiums over government debt. BlackRock’s survey found nearly a third of insurers planned to increase private‑market allocations and a majority intended to maintain them, even amid low risk appetite. That reallocation can both improve ALM outcomes and support long‑term returns needed to fund guarantees, but it raises governance, liquidity and valuation challenges that supervisors monitor closely.

Limits, trade‑offs and open risks
Despite the rapid pace of hedging and reinsurance activity, the industry faces material constraints and new risks:
-
Counterparty and basis risk: Longevity hedges and derivatives introduce counterparty credit exposure; large transfers depend on reinsurance market capacity and the willingness of counterparties to bear long‑dated tail risk. Index‑based solutions can leave basis risk if portfolio mortality deviates from the index. (researchgate.net)
-
Pricing and capacity cycles: An influx of reinsurance and alternative capital has, in some lines, depressed reinsurance pricing and changed risk–return tradeoffs — a dynamic that can narrow the incentives for some reinsurers to provide deep tail protection at sustainable returns. Brokers and reinsurers warned that the market structure was evolving as capital flows continued to expand. (insurancebusinessmag.com)
-
Medical‑cost uncertainty: Rapid shifts in pharmaceutical utilization patterns (for example, GLP‑1 therapies), adoption of expensive specialty medicines and changes in hospital pricing can cause claim severities to jump in ways that are difficult to model precisely. Aon and others forecast double‑digit medical trend rates in many markets, a source of concern for employers, insurers and supervisors. (prnewswire.com)
-
Accounting and economic trade‑offs: Hedging to protect regulatory capital can affect reported earnings under IFRS and other accounting regimes; insurers must balance solvency resilience with profitability and shareholder capital management. Some firms opt for partial rather than full hedges to preserve upside on asset returns. Industry coverage shows sophisticated hedging often involves dynamically balancing solvency‑protective trades with earnings objectives. (wtwco.com)
Voices from the market
Industry leaders and advisers emphasize the dual nature of the response: tactical protection of capital ratios and strategic repositioning for a structurally different risk environment.
“Insurers are bracing for another year of uncertainty,” Charles Hatami, global head of BlackRock’s Financial & Strategic Investors Group, said in BlackRock’s 2025 Global Insurance Report. “The story of 2025 is one of caution amid volatility, but also of conviction in the long‑term opportunities private markets can offer.” (blackrock.com)
“Our analyses show medical cost inflation levels at their highest in years,” Farheen Dam, head of Health Solutions for North America at Aon, said in Aon’s 2026 projection, warning employers and insurers about the cost dynamics that will feed insurer claim trends. (prnewswire.com)
“The capital uplift and economics from these transactions are very attractive compared to the limited impact on operating capital generation,” NN Group Chief Executive David Knibbe said of NN’s longevity transfers, illustrating the clear commercial rationale behind large longevity‑risk exchanges. (reinsurancene.ws)
Outlook: durable shift or temporary cycle?
The near‑term outlook points to continued hedging and capital‑management activity. Regulators’ work on global capital standards and supervisory expectations for risk management has hardened incentives for explicit hedging; at the same time, persistent medical and claims inflation keeps pressure on reserves and earnings. Industry surveys and market activity suggest the changes are more than a short‑term defensive reaction: many insurers are embedding more flexible asset‑management models, greater third‑party capital, and technology‑enabled risk analytics into their operating models — structural adjustments that are likely to persist even if inflation recedes. (blackrock.com)
But the effectiveness of the shifts will depend on three variables: the availability and price of long‑dated reinsurance and capital, the trajectory of medical and pharmaceutical costs, and the ability of insurers to measure and hedge basis risk between portfolio experience and available index or reinsurance structures. If medical costs continue to rise faster than pricing and reserve updates, or if longevity improvements accelerate beyond hedged assumptions, insurers could face renewed pressure despite current actions. (prnewswire.com)
For now, insurers’ stronger capital positions — reflected in many firms’ elevated solvency ratios and in supervisory reports that describe the sector as “robust and well‑capitalised” — give them latitude to pursue measured hedging and reinsurance strategies rather than emergency balance‑sheet fixes. But boards and supervisors increasingly treat hedging and longevity management as core capital‑management disciplines rather than optional risk‑transfer projects. That marks a notable shift in industry practice: a movement from ad‑hoc de‑risking toward integrated, ongoing capital‑defense programs. (eiopa.europa.eu)
