世界の富裕層（high-net-worth、HNW）向け生命保険市場は、現在の金融サービス業界において最も有望な成長分野の一つです。世界の個人富裕層資産が急速に拡大し、世代間の資産移転が加速し、さらに国境を越えた規制・税務環境がますます複雑化するなか、保険をベースとする高度なウェルス・ソリューションに対する需要は、かつてないほど高まっていると考えられます。しかし、生命保険市場の浸透度は依然として著しく低く、保険が取り込んでいるのは、世界の富裕層の投資可能資産の約2％¹にすぎません。

この有望分野の規模と戦略的重要性にもかかわらず、富裕層向け生命保険市場に特化した包括的な調査は限られています。既存の業界調査は、保険特有のダイナミクスを十分に掘り下げることなく、より広範なプライベート・ウェルス・マネジメント領域を扱うものか、あるいは個別の商品や規制上のトピックを単独で取り上げるものが中心であり、保険会社の視点から富裕層市場のより広範な戦略的意味に落とし込むものは多くありません。ミリマンの世界の富裕層に関するレポートは、こうしたギャップを埋めることを目的としています。

The global high-net-worth (HNW) life insurance market represents one of the most compelling growth opportunities in the financial services industry today. Against a backdrop of rapidly expanding global private wealth, an accelerating intergenerational transfer of assets, and increasingly complex cross-border regulatory and tax environments, the demand for sophisticated insurance-based wealth solutions has arguably never been greater. Yet the life insurance market remains strikingly underpenetrated, with insurance capturing only approximately 2%¹ of the global HNW investable asset base.

Despite the scale and strategic significance of this opportunity, comprehensive research specifically focused on the HNW life insurance market remains limited. Existing industry literature tends to address either the broader private wealth management landscape, without sufficient depth on insurance-specific dynamics, or individual product and regulatory topics in isolation, without situating them within the broader strategic context of the HNW market from an insurer’s perspective. Milliman’s Global High-Net-Worth report aims to address that gap.

Drawing on Milliman’s proprietary market knowledge, market data, and cross-jurisdictional product and regulatory expertise, the report examines the HNW market across six interconnected dimensions.

1. The scale and composition of global HNW wealth pools, including projected growth trajectories and the opportunities emerging in Asia
2. The structural demand drivers shaping HNW client needs, from legacy planning and the “great wealth transfer” to wealth accumulation, global mobility, and tax efficiency
3. The insurance product landscape covering the five principal HNW insurance solutions—participating whole life (par WL), universal life (UL), indexed universal life (IUL), variable universal life (VUL), and private placement life insurance (PPLI)—and their respective client propositions, market trajectories, and risk profiles
4. The distribution models through which HNW insurance is originated and delivered, including the onshore-offshore (local-international) premium flow dynamics that typically characterise this market
5. The role of reinsurance in enabling insurers in the HNW space
6. The key challenges and risks facing HNW market participants

A more detailed report elaborating on the findings can be made available to key clients upon request. Please email one of the authors or your usual Milliman consultant. Due to the proprietary nature and commercial sensitivity of the main report, the full report will not be publicly available at this time.

Overview

The global HNW life insurance sector stands at a significant operational and strategic inflection point. Global HNWI wealth experienced an explosive 8.7% expansion in 2025, reaching a record USD 98.3 trillion.² This momentum was led by the Asia-Pacific region, followed closely by North America and Europe.

However, a stark disconnect remains between global private wealth growth and insurance asset allocation. Of the USD 98.3 trillion in global HNWI financial wealth, highly liquid investable assets represent approximately two-fifths (roughly USD 40 trillion).³ Strikingly, insurance-based wealth solutions currently capture only about 2% of this investable pool. This structural underpenetration presents a material growth opportunity for life insurers capable of deploying targeted product innovation, optimising cross-border distribution models, and structuring sophisticated reinsurance partnerships to confidently write high sum assured (SA) policies.

Observation 1: The underpenetrated multi-trillion-dollar global wealth opportunity

As of 2026, the world’s HNW and ultra-high-net-worth (UHNW) populations collectively hold an estimated USD 98.3 trillion in total financial wealth. This global wealth pool is projected to expand at a compound annual growth rate (CAGR) of 6.9% through 2030, with the Asia-Pacific region leading as the fastest-growing wealth engine at a projected CAGR exceeding 9%, based on Milliman estimates.

Despite this immense scale, insurance-based wealth structures capture approximately 2% of HNW investable assets. This low baseline is primarily driven by limited client awareness of modern insurance product offerings and systemic distribution bottlenecks. For forward-looking insurers, this low baseline represents a highly leveraged growth opportunity. Assuming a reasonable target where strategic market developments increase insurance penetration by just 100 basis points from 2% to 3%, the global HNW life insurance market would instantly unlock an estimated USD 400 billion in new asset inflows.

Observation 2: Legacy planning and asset accumulation as dominant demand drivers

HNW wealth owners exhibit highly specialised financial needs that differ fundamentally from the mass market. The primary demand drivers for HNW life insurance products remain structured legacy planning, accelerated by the impending intergenerational “Great Wealth Transfer” of tens of trillions of dollars, and robust capital accumulation and preservation.

While the intergenerational Great Wealth Transfer remains a critical tailwind, HNWIs are increasingly recognising modern savings-oriented life insurance as a distinct asset class capable of delivering highly competitive, stable, and risk-adjusted returns. This structural shift is driven by a fundamental repositioning of product design. Some of the more recent insurance product propositions, such as participating structures, democratise access to premium illiquid return streams like private equity and private credit by wrapping them in a structure that simultaneously provides policyholder liquidity through partial withdrawals, regular bonuses, and policy loans.

Furthermore, this asset class has become highly leverageable and competitive. With HNW life insurance products offering high guaranteed day-one cash surrender values that typically exceed 80% of premiums paid from inception, clients can utilise premium financing, borrowing against the policy’s cash value to build coverage while keeping their primary capital deployed elsewhere. Combined with substantially compressed breakeven timelines, savings insurance can now compete with traditional bonds for the fixed income portion of HNW and family office portfolios.

Observation 3: Hong Kong HNW preference for participating structures versus global indexed universal life dominance

The global HNW insurance landscape exhibits a distinct geographical bifurcation in product preferences. HNWIs in Asia, particularly in Hong Kong, continue to show a strong preference for participating products. This enduring dominance of par products in new business is underpinned by historically stable returns smoothed by participating funds, a favourable local regulatory environment, and an advisory force highly trained in explaining participating mechanics. On the contrary, IUL has been the key HNW product sold in Singapore over the past few years, replacing the traditionally favoured participating and UL products.

Outside of Asia, IUL is the dominant wealth accumulation and protection vehicle in North America and the Middle East. The product’s options-based crediting mechanism combines equity market upside participation with a contractual downside floor. Although a higher interest rate environment and established regional sales forces will ensure that par WL maintains its clear market leadership in Hong Kong, IUL is poised to capture substantial growth momentum as it expands into Singapore and other wealth corridors across the rest of the world.

Observation 4: Centralised versus decentralised operating model for HNW business

Insurers typically deploy one of two operational frameworks to manage their cross-border HNW distribution.

1. The centralised model integrates sales, relationship management, and underwriting under a single global desk, enabling seamless cross-jurisdictional product offering (e.g., offering Hong Kong, Singapore, or Bermuda booking structures from a single contact point).
2. The decentralised model delegates sales and profit and loss (P&L) accountability entirely to individual local business units (LBUs), which might discourage cross-border collaboration and forces international brokerages to navigate multiple local desks.

A key operational trend is the strategic utilisation of offshore entities, such as Bermuda subsidiaries, to write HNW or UHNW business. Due to the superior efficiency and speed of centralised underwriting and distribution, an industry migration is underway as carriers currently utilising decentralised models look to transition to centralised frameworks, despite the substantial organisational and incentive realignments required to do so.

Observation 5: Three key challenges for HNW business: Margin compression, operational friction and expertise, and capacity constraints

Entering and competing in the HNW space exposes insurers to three key financial and operational challenges that demand significant strategic preparation.

Key challenge 1—Margin compression and financial volatility: Intense distributor competition and high acquisition costs heavily compress product margins. Furthermore, high day-one cash value designs expose carriers to severe surrender and disintermediation risks during rising interest rate cycles, especially within premium-financed portfolios.

Key challenge 2—Operational friction and response speeds: Fragmented, decentralised operating models could be a major bottleneck. International brokerages have to interface with multiple LBUs individually, dispersing specialised underwriting expertise and dragging down transaction turnaround speeds where rapid execution is highly critical.

Key challenge 3—Jumbo HNW case capacity constraints: Writing jumbo policies exceeding USD 100 million on a single life requires massive underwriting capacity. To compete, insurers must master complex risk-syndication frameworks, seamlessly blending external treaty and facultative reinsurance panels with in-house group captives to maximise retention and capital efficiency.
