With regards to pensions and retirement, we have now a transparent pensions adequacy issue in much of the world provided that the inhabitants resides longer and plenty of people have insufficient financial savings for a cushty retirement. Bitcoin fixes this – partly – by providing a type of financial savings which may’t be debased and may maintain its worth into the long run. Reducing our collective time choice as a society additionally wouldn’t harm, as we’d prioritise our later years greater than we achieve this at current.
It’s generally remarked although that Bitcoin doesn’t resolve all the issues on this planet, solely half of them, and there’s one big side Bitcoin can not assist with when it comes to retirement planning. Specifically, none of us know the way lengthy we’re going to reside for, and if we reside “too lengthy” we face the chance of operating out of cash in previous age. It is a drawback which the pensions and insurance coverage world defines as “longevity threat”.
I wrote an article for Bitcoin Journal in 2022 on one answer, which may be seen here. Briefly, it proposed a easy annuity product priced in Bitcoin and that will pay policyholders a Bitcoin earnings for all times, permitting contributors to pool their longevity threat in retirement.
Remarkably, there’s now a product coming to market that permits bitcoiners to pool their longevity threat right into a Bitcoin based mostly belief and be paid an earnings for all times, however with extra transparency and certain the next earnings than an annuity. Enter the Bitcoin Tontine by Tontine Trust.
Let’s run by the fundamentals.
What’s a Tontine and the way does it work?
A Tontine is historically generally known as an funding linked to a residing individual that operates to pay them an earnings for so long as they reside. Every participant pays into their very own segregated belief. Every belief designates a Tontine Class because the beneficiary of their belief upon their dying. The Tontine Class is comprised of numerous others of comparable age and intercourse. A various earnings is then paid to every member out of their very own account. When a member of the Tontine Class dies, the entire worth leftover of their belief will get allotted proportionately into the person belief accounts of all of the remaining class members, thus serving to to spice up their retirement earnings over time. This course of continues till the second final member dies.
The earnings paid is constantly up to date, and is calculated to make sure an earnings for all times for all contributors based mostly upon the next components –
a) the members life expectancy which is basically based mostly upon age / intercourse
b) the present worth of their funding fund
c) the anticipated annual return on their fund
This technique means the earnings might generally go down in addition to up nonetheless it’s this flexibility which in flip mathematically ensures that members won’t ever run out of earnings in retirement. The Tontine Belief cowl the prices of operating the tontine through a flat annual trustee payment of 1% levied on every belief account.
How does this differ to an Annuity?
An annuity ensures a hard and fast earnings (or an earnings with outlined will increase, e.g. 3% each year) for all times at outset. If members reside far longer than anticipated, it would fall on the insurer to soak up that value (and conversely, they are going to revenue if members die younger). Because of this requirement, insurers have strict necessities to carry extra capital to cowl all eventualities, and have a tendency to cost their annuities based mostly on the return on fastened earnings authorities bonds. Their income are opaque and are realised over a few years.
Against this the tontines supplied by the Tontine Belief work in an especially clear and intuitive method, and attributable to their nature can supply a spread of trustee permitted asset courses for the underlying investments. Furthermore, members can change their funding technique over time. Alongside a pure allocation to Bitcoin, they provide funding methods for various threat appetites & circumstances, together with a “Daring” fund (mixture of Bitcoin and Gold), index funds, and cash market funds.
The upper returns of underlying investments together with the mechanisms of a tontine ought to be sure that contributors get pleasure from the next earnings all through retirement because of this, vs an annuity. The principle trade-off is that earnings paid can fall in addition to rise attributable to funding returns.

What are the downsides of Tontines?
In a Tontine the longevity of members will straight impression on the payouts to the remainder of the group (relatively than in an annuity, the place how lengthy members reside for will impression on the income of an insurer). Because of this, arguably the principle threat for tontine fiduciaries is the potential for fraud, and family of members pretending they’re nonetheless alive after their dying (after all, insurers additionally bear this threat).
Tontine Belief has provide you with a brand new technological option to fight the potential for fraud, patenting a brand new proof of life technique whereby members reveal they’re nonetheless alive through the Tontine Belief app to validate funds to them. As well as, as every member has their very own segregated account, the Tontine Belief are capable of observe a proof of reserves system, utilizing blockchain to assist transparency and replicate all funds and costs out and in of members accounts.
It might be {that a} public relations marketing campaign is required to coach the general public on this new sort of Tontine product. Tontines have a wealthy and assorted historical past, courting again to the seventeenth century. The place lined in fiction, Tontines have usually concerned cloak and dagger tales of private Tontine arrangements, usually whereby the final surviving member of a small group will inherit the lot. In actuality, the trendy day Tontine swimming pools will function at scale and with anonymity.

As well as, Tontines have been restricted from sale in the US on sure life insurance coverage insurance policies following the Armstrong investigation of 1905, because the phrases of those insurance policies led to sure types of malpractice by lots of the insurance coverage firms of the time. There have been some questionable phrases for shoppers with these merchandise, equivalent to a default on the coverage for lacking a single common cost, and excessive fee charges payable to gross sales brokers. These points as summarised within the paper here have been particular to the merchandise and practices of the time, relatively than a basic drawback with a retirement Tontine as listed above.
How do Tontines sit with present regulation?
Tontines are very long run merchandise managed in the very best pursuits of members by fiduciaries and as such are much like pensions and different trustee providers. They don’t fall beneath insurance coverage regimes, for the reason that maintencance of a separate capital reserve isn’t wanted to insulate in opposition to members residing for a very long time. Crucially, there have been latest developments in favour of Tontines but once more being launched as a product.
In 2022, the OECD (Organisation for Financial Co-operation and Improvement) printed a legal instrument recommending that Outlined Contribution pension plans (which at the moment are the norm in most international locations) guarantee safety in opposition to longevity threat in retirement. This may very well be achieved by offering Lifetime earnings which “may be offered by annuities with assured funds or by non-guaranteed preparations the place longevity threat is pooled amongst contributors”. They word that the selection made will depend upon the stability required between the price of ensures (i.e. annuities give a assure of an earnings, however could also be worse worth) and stability of retirement earnings (i.e. preparations equivalent to tontines could generally see earnings lower over time from adversarial funding returns).
Additional to this, Donald Trump just lately signed an executive order in August 2025 searching for to democratise entry to various belongings, which not solely outlines entry to incorporate “holdings in actively managed funding automobiles which are investing in digital belongings”, but additionally to “lifetime earnings funding methods together with longevity risk-sharing swimming pools”. This basically paves the best way for Tontines as a retirement possibility, and for the underlying funding to be Bitcoin.
Arguably, that is the social safety system of the long run. Nationwide Tontines backed by Bitcoin might rapidly develop into essentially the most safe method for governments to make sure that their populations have an inflation proof earnings to maintain them in previous age. The “pay as you go” mannequin for state pensions as employed in lots of international locations will proceed to return beneath pressure attributable to demographic shifts. Though a shift to a funded mannequin is a big one, it then solves for inter generational equity and comes at zero value to the state.
Abstract
17 years after the unique Bitcoin whitepaper, we’re about to see a pure retirement possibility launched for bitcoiners – a long life threat sharing pool with the advantages of bitcoin returns and which allows bitcoiners to mathematically assure an earnings for all times. This appears more likely to pay a a lot larger earnings than an annuity can supply. A alternative going through these searching for a lifetime retirement earnings can be from a) an annuity priced by returns on fastened earnings authorities debt, and b) a tontine powered by Bitcoin returns.
Over time, the market will resolve.
