Source note: This installment relies primarily on current full-year official disclosures from Allianz, Allianz’s FY 2025 financial supplement, Generali, AIA, Sun Life, Manulife, and MetLife; plus the supervisory and accounting frameworks that make those numbers readable, including EIOPA’s Solvency II page, the IFRS Foundation’s IFRS 17 page, OSFI’s LICAT materials, and NAIC’s RBC materials. The goal is not to create one fake league table. The goal is to separate owned balance-sheet assets, invested assets, linked or separate-account assets, third-party AUM, liabilities, and capital so the comparison stays honest.

Module 10 — Comparative Scale of the Largest Global Insurers

Comparing the Largest Global Insurers: Assets, Liabilities, and Capital

The biggest insurer depends on what you are measuring. A company can look huge because it owns a very large balance sheet, because it manages a very large outside asset pool, because it carries a large linked-account book, or because it reports strong solvency capital. Those are different buckets of money doing different jobs.

Scope

Global multi-line and life-led insurance groups using the latest full-year official reports.

Period

Year-end 2025 disclosures, with 2026 investor pages used only where they surface year-end 2025 figures.

Reporting basis

IFRS 17, Solvency II, LICAT, shareholder-capital reporting, and U.S. GAAP plus statutory-capital context.

Main test

Separate what the insurer owns, what it manages, what is ring-fenced for linked business, and what capital sits underneath the liabilities.

Main finding

There is no single honest “largest insurer” number

The usual shortcut is to ask who has the biggest AUM. That shortcut breaks almost immediately. Some insurers disclose very large managed asset pools that include outside client money. Some disclose separate-account or segregated-fund assets that are tied to linked liabilities. Some disclose only insurer-owned invested assets. Some disclose strong group solvency ratios. Some, especially in the United States, disclose large consolidated balance sheets in SEC filings while the core solvency tools sit mainly at the regulated legal-entity level rather than in one simple group ratio.

That means the words largest insurer need to be unpacked before they mean anything. You have to separate at least five layers: the insurer’s total assets, the invested assets supporting liabilities, the linked or separate-account bucket, outside assets under management, and the capital framework that sits under the whole structure.

Wrong shortcut

One headline AUM number

AUM can include outside client money, segregated or separate-account assets, and other administered assets that do not belong to the insurer in the same legal sense as general-account assets.

Better bucket

Owned balance-sheet assets

This is the broadest view of the resources actually sitting on the insurer group’s books. It is still not enough by itself, but it is closer to the actual financial machine.

Critical bucket

Invested assets supporting liabilities

This is the asset pool that most directly matters when you are asking how promises are financed and how claims or benefits are expected to be met over time.

Do not blur

Linked and ring-fenced asset pools

Separate accounts, unit-linked assets, and segregated-fund assets are often large, but they are not the same thing as freely available general-account support for every other liability.

Historical lens

The comparison only makes sense inside the reporting regimes that created the numbers

Insurance scale was never just a question of who collected the most premium. It became a question of how law, accounting, and solvency supervision forced insurers to show what they owned, what they owed, and what capital sat underneath the promises. That is why a modern comparison has to read the numbers through the regime that produced them.

1906

Marine Insurance Act 1906: a mature contract-law expression of the older insurance idea that policy obligations are claims on an insurer, not little bags of cash with one owner’s name on them.

2016

Solvency II goes live in Europe: the EU moves group insurance supervision onto a modern risk-based framework built around technical provisions, capital requirements, governance, ORSA, and public disclosure.

2018

LICAT becomes Canada’s main life-capital framework: the Canadian comparison starts using a different risk-based capital grammar than European Solvency II even when both are talking about capital strength.

2023

IFRS 17 becomes effective: major insurance groups reporting under IFRS begin showing insurance liabilities, service result, and insurance finance effects on a more modern common accounting base.

2025

Current public comparison: the latest full-year disclosures make clear that mega-insurers still disclose different kinds of scale at the same time: owned assets, invested assets, linked assets, outside AUM, and capital coverage.

Method

Normalize the comparison before you rank anything

This comparison uses a simple discipline. First, take the published total assets. Second, isolate the investment pool and any clearly disclosed linked or separate-account bucket. Third, identify liabilities and equity or capital. Fourth, only then look at AUM or AUMA, and keep those numbers in a separate lane if they include money managed for others.

Normalization flow used in this installment

This is the order used to keep unlike money pools from being mixed into one misleading ranking.

1. Start with total assets Use the group balance sheet first. This is the widest official view of what sits on the insurer’s books.

2. Pull out the investment pool Identify the insurer-owned invested assets or total investments that actually support liabilities.

3. Isolate linked buckets Separate unit-linked, segregated-fund, or separate-account assets from the general-account pool.

4. Read liabilities next A big asset pool means little without the liability stack that sits on top of it.

5. Add capital last Equity and solvency ratios matter, but the ratios come from different regimes and should not be mashed together carelessly.

6. Keep AUM in its own lane Managed assets can be economically important, but they are not automatically claim-paying assets of the insurer.

Plain-English rule: the money an insurer manages is not automatically the same thing as the money an insurer owns.

The insurer that looks biggest in one column may not look biggest in the column that actually supports the promise you are studying.

AUM, invested assets, total assets, separate-account assets, liabilities, and solvency capital answer different questions. The comparison only becomes useful when those questions stay separate.

Balance sheets first

Normalized balance-sheet comparison

The first table keeps the comparison as close as possible to owned insurance-group resources and obligations. Figures stay in native reporting currency to avoid false precision from forced exchange-rate conversion. Where a liability figure is calculated rather than directly surfaced in the selected extract, it is labeled that way.

Owned assets, liabilities, linked buckets, and capital

All figures are year-end 2025. The purpose is not to crown a winner. The purpose is to show which money bucket is being measured.

Group	Reporting lens	Total assets	Invested assets / total investments	Linked / separate / segregated bucket	Total liabilities	Equity / main capital indicator	Read this company as…
Allianz	IFRS 17 + Solvency II	€1,024.3bn	€753.5bn investments	€158.2bn financial assets for unit-linked contracts	€957.9bn	€62.7bn shareholders’ equity; Solvency II ratio 218%	A very large insurer-owned balance sheet with a major linked-assets bucket and a separate giant asset-management franchise.
Generali	IFRS 17 + Solvency II	€558.5bn	€516.2bn total investments	€136.1bn unit-linked investments	€523.7bn	€32.1bn group equity; Solvency II ratio 219%	A large insurer whose size expands sharply once external AUM is brought into view.
AIA	IFRS 17 + group capital resources / LCSM	US$345.4bn	US$285.2bn total invested assets	Not isolated in the selected high-level extract	US$301.8bn	US$43.6bn total equity; shareholder capital ratio 221%; shareholder capital resources US$41.1bn	A life-heavy balance sheet with a dense invested-asset base and strong explicit capital-resource disclosure.
Sun Life	IFRS 17 + LICAT	C$398.5bn	C$199.2bn invested assets	C$166.6bn investments for account of segregated fund holders	C$373.0bn	C$25.5bn total equity; LICAT ratio 157%	An insurer and asset-manager combination where the platform looks much bigger than the claim-supporting general fund alone.
Manulife	IFRS 17 + LICAT	C$1,025.4bn	C$459.9bn total invested assets	C$461.3bn segregated funds net assets	C$972.9bn (calculated as assets less total equity in the cited extract)	C$52.5bn total equity; consolidated capital C$81.6bn; LICAT ratio 136%	A very large balance-sheet insurer with a second very large segregated-fund lane and a still larger managed-asset platform.
MetLife	U.S. GAAP group reporting + statutory-capital context	US$745.2bn	US$472.2bn total investments	US$151.9bn separate-account assets	US$716.2bn	US$28.4bn group equity; U.S. RBC remains mainly a legal-entity regulatory tool rather than a single published group ranking ratio	A very large U.S.-listed insurance balance sheet whose public capital story cannot be reduced to one simple group solvency percentage.

The balance-sheet table already kills the lazy ranking. Allianz and Manulife are giant by owned group assets. MetLife is also very large by owned group assets. Generali looks smaller by total balance-sheet size than Allianz or Manulife, but it becomes much larger if you move out of the balance sheet and start counting managed third-party money. Sun Life looks modest by total assets relative to some peers, yet its overall AUM platform is enormous. AIA is smaller by total assets than the biggest European and North American names in this table, but it still shows a very large invested-asset base and a strong disclosed capital-resource position.

AUM lane

Management-platform scale is real, but it is not the same as claim-paying ownership

The next table moves into the AUM lane on purpose. These figures matter because they drive fee income, distribution power, market influence, and platform scale. But they should not be confused with insurer-owned general-account support for policy promises.

AUM and managed-asset disclosures

These figures are economically important. They are not interchangeable with insurer-owned invested assets unless the source expressly says they are.

Group	Managed-asset disclosure	Why the number gets large fast	What to remember
Allianz	€1.990tn third-party AUM; €2.512tn total AuM	The group combines a very large insurer-owned balance sheet with a major global asset-management franchise through PIMCO and AllianzGI.	Do not add the full asset-management number to the insurance balance sheet and pretend it is one pool of claim-paying money.
Generali	€383.8bn third-party AUM; €899.9bn total AUM	The group’s reported AUM becomes much larger than its €558.5bn balance sheet once outside managed money is included.	The AUM figure is real platform scale, but it is not the same thing as insurer-owned assets backing liabilities.
Sun Life	C$1,604.9bn total AUM	Sun Life’s asset-management, segregated, retail, institutional, and managed funds push the overall platform far above the insurer group balance sheet.	The platform is huge, but the general fund that directly backs broad insurer obligations is much smaller.
Manulife	C$1,458.4bn total AUM; C$1,704.4bn assets under management and administration	Manulife combines a large general fund, a large segregated-fund business, and a large outside managed-asset franchise.	Manulife explicitly says these managed or administered assets are not available to satisfy the liabilities of the company’s general fund.

Plain-English rule: AUM is a scale number. It is not automatically a claims-paying number.

An insurer can look huge because it owns assets, because it manages assets, or because it carries linked assets for policyholders. Those are not the same financial job.

The comparison gets serious only when each bucket is left in the legal lane it actually belongs to.

Legal buckets

Which asset pools can actually support general-account claims?

This is the question most “largest insurer” lists never answer. The answer depends on what legal bucket the assets sit in and what liabilities they are already tied to.

Asset buckets and what they can usually do

This is a practical reading tool, not a substitute for contract terms, ring-fencing rules, or local law.

Bucket	What it usually includes	Can it generally support broad general-account claims?	Why the answer is limited
General-account invested assets	Bonds, mortgages, loans, real estate, funds, and cash owned inside the insurer’s core balance sheet.	Usually yes	This is the classic claim-supporting pool, subject to legal-entity boundaries, regulation, and existing liability needs.
Unit-linked / separate-account / segregated-fund assets	Assets tied to linked liabilities or policyholder-directed accounts.	Not automatically	These assets are usually there first to support those linked liabilities, not to be freely redeployed to unrelated obligations.
Third-party AUM	Money managed for clients outside the insurer’s own balance sheet.	No	This supports fee income and platform scale, but it is not insurer-owned claim-paying capital.
Equity and eligible capital	Common equity, retained earnings, qualifying hybrid capital, and other recognized capital resources.	Supports the system, not each policy directly	Capital absorbs loss and supports solvency, but it is not the same thing as booked insurance liabilities or reserves.
Reinsurance recoverables	Claims on reinsurers or liability reductions recognized under local rules.	Conditional	The value depends on treaty terms, collateral, counterparty performance, and local accounting or capital treatment.

This is why the phrase follow the money matters. If the money sits in a managed-account lane, a linked-account lane, or a different legal entity, you cannot just pull it into a general claims-paying story because the headline number looks impressive.

By company

What each company’s numbers are really telling you

The goal here is not to praise or attack any firm. It is to read the structure honestly.

Allianz

Big on both the insurance side and the asset-management side

Allianz shows one of the biggest insurer-owned balance sheets in the group, a very large investment pool, a material unit-linked bucket, and very large third-party AUM through its asset managers. It is one of the clearest examples of why one number cannot do all the work.

Generali

Smaller balance sheet than Allianz, much larger once AUM is counted

Generali’s general-account-plus-linked investment base is large on its own. But the group looks materially bigger when total AUM is counted, because outside managed assets sit on top of the insurer-owned balance sheet.

AIA

Life-led scale with dense invested-asset and capital disclosures

AIA looks smaller than the very largest European and North American groups by total assets, but it still carries a large invested-asset base relative to its own size and publishes a clear shareholder-capital-resource measure.

Sun Life

AUM-heavy platform with a smaller core balance sheet underneath

Sun Life is a good reminder that a very large platform number can sit above a much smaller group balance sheet. The insurer is large, but the overall platform becomes much larger when asset management and segregated funds are added.

Manulife

Two large insurance buckets plus an even larger managed-asset platform

Manulife is especially useful for this series because it discloses a very large general fund, a very large segregated-fund lane, and a very large AUM or AUMA figure, while also stating that managed or administered assets are not available to satisfy general-fund liabilities.

MetLife

Huge group balance sheet, but a different capital-reading problem

MetLife’s SEC filing shows a very large balance sheet, large investments, and a major separate-account bucket. But the capital comparison is not plug-compatible with Solvency II or LICAT disclosures. In the U.S. system, the key solvency tools remain heavily anchored in the statutory legal-entity framework.

Capital logic

Why the capital ratios are not one universal scoreboard

A 218% Solvency II ratio and a 157% LICAT ratio are both meaningful numbers, but they are not the same formula wearing different logos. They come from different frameworks, different capital definitions, and different supervisory traditions. AIA’s shareholder capital ratio is another distinct measure. MetLife’s public group filing shows equity and liabilities, but the U.S. statutory capital story lives more heavily in regulated insurance entities and the RBC system.

Solvency II groups

Allianz and Generali give you a direct group solvency ratio built on own funds over SCR. That makes their disclosed capital coverage legible, but only inside the Solvency II framework.

Canadian LICAT groups

Sun Life and Manulife publish LICAT ratios. LICAT is risk-based and designed to measure available versus required capital for life insurers, but it is not numerically identical to Solvency II even if both are doing solvency work.

AIA’s capital reporting

AIA publishes shareholder capital resources, required capital, and shareholder capital ratio, alongside its Group LCSM coverage ratio. That makes the group’s capital story readable, but again not directly identical to the European or Canadian measures.

U.S. statutory context

NAIC’s own materials say RBC is a regulatory tool and not intended to rank insurers. That matters when people try to compare a U.S. group’s SEC balance sheet to a published European group solvency ratio as if they were the same kind of disclosure.

Plain-English rule: capital ratios travel badly across systems unless you first understand the formula that produced them.

The wrong ranking asks who has the biggest number. The right ranking asks which number belongs to which legal bucket.

Comparative insurance rule

What goes wrong

What usually gets misstated in insurer “largest company” lists

Most bad comparisons fail for the same reasons. They are not mathematically wrong so much as financially sloppy.

Common mistake

Treating AUM like owned claim-paying assets

A large asset-management platform can make a company look huge, but third-party managed money is not the same thing as the insurer’s own general-account support for policy obligations.

Common mistake

Adding linked-account assets to general-account stories

Separate-account, segregated-fund, and unit-linked assets often back linked liabilities first. They should not be treated like spare balance-sheet cash.

Common mistake

Comparing capital ratios as if the formulas are identical

A Solvency II ratio, a LICAT ratio, and a U.S. statutory-capital measure are all useful, but they are not one universal score.

Common mistake

Ignoring the liability side

A huge asset number says very little without the liability stack sitting against it. Insurance is a liability business before it is an asset story.

Common mistake

Forcing a currency-converted ranking

Quick exchange-rate conversion can create a neat-looking list, but it often hides the more important issue: which assets are owned, which are linked, and which are managed for others.

Common mistake

Using brand familiarity instead of filed disclosures

Marketing pages can tell you a company exists. They usually cannot tell you how the money is actually structured inside the group.

Observed vs unknown

What this comparison can show, and what it still cannot show

This project is trying to stay as close to 100% transparency as public documents allow. That still leaves hard limits. A comparison of published totals is not a full map of internal legal-entity fungibility, hidden management actions, or the exact way each group would mobilize assets under stress.

Evidence status for this installment

This is the discipline that keeps the series factual instead of narrative-driven.

Status	What we can say	Examples in this installment
Directly observed	Published totals in official reports, supplements, or filings.	Total assets, liabilities, investments, separate-account or linked-asset buckets, equity, AUM, Solvency II ratios, LICAT ratios, shareholder capital resources.
Calculated	Simple arithmetic using directly observed figures.	Manulife liabilities in the main table, backed out from total assets less total equity because the selected extract surfaces those two values clearly.
Constrained inference	Limited conclusions drawn from structure rather than hidden internal data.	AUM-heavy groups have broader fee platforms than their owned balance sheets alone would suggest; linked-asset-heavy groups need tighter bucket separation when analyzing claim support.
Still unknown	Items not fully visible from public sources.	Exact internal legal-entity transfer capacity, emergency liquidity sequencing, nonpublic hedging overlays, detailed collateral terms, and management playbooks under severe stress.

What this means: the public record can take you very far on scale, structure, and disclosed solvency. It cannot give you full x-ray vision into every internal funding decision of every giant insurance group.

Why Globe later

Why a Globe Life comparison belongs at the end, not the beginning

The right way to compare a smaller insurer with global giants is to normalize the buckets first. Once the framework above is in place, a later Globe Life comparison can ask disciplined questions: How large is the actual balance sheet? What product mix dominates? How large is the invested-asset base? How much of the story is general-account life insurance versus other lines? What does the public capital and reserve framework show, and what remains nonpublic?

That is a much better comparison than using brand familiarity, sales language, or one loose “largest insurer” ranking. It keeps the project on the money trail instead of drifting into opinion.

Glossary

Plain-English glossary for this comparison

Total assets

The broadest balance-sheet view of what the insurer group reports that it owns or controls under the reporting rules it uses.

Invested assets

The portfolio of bonds, mortgages, loans, funds, cash, and other investments that supports liabilities and earns investment income.

Unit-linked / separate-account / segregated-fund assets

Assets tied to linked or policyholder-directed liabilities. Large, important, and often not freely interchangeable with general-account support.

AUM

Assets under management. A scale number for a management platform. It can include money that belongs to outside clients.

AUMA

Assets under management and administration. Usually even broader than AUM because it can include assets serviced or administered in addition to assets actively managed.

Equity

The residual value after liabilities are subtracted from assets. It absorbs loss and helps support solvency.

Solvency ratio

A capital-coverage measure published under a particular regulatory framework. Useful, but not universal across jurisdictions.

LICAT

Canada’s Life Insurance Capital Adequacy Test. A risk-based capital framework used by OSFI to assess whether life insurers hold enough capital for the risks they take.
