How to Hold an Assurance Vie in Sterling — and What It Actually Means

• A standard French-domiciled Assurance Vie is, in practice, euro-only — French insurers essentially never offer a sterling option on their standard contracts
• There are 2 options for GBP Sterling Assurance Vie Policies: a Luxembourg-domiciled contract (genuinely multi-currency by design), or a UK/Irish (Prudential) "international bond" marketed to sit inside the wrapper from outside France
• Holding sterling removes FX risk on the way in, but you'll eventually spend euros in France — the currency risk doesn't disappear, it just moves to the point you withdraw
• Either route is taxed the same way as any other Assurance Vie for French purposes — the currency the contract is denominated in doesn't change the tax treatment

Why Open a Sterling Assurance Vie

If you are moving to France with savings or a large sum from a house sale, converting everything to euros on day one can feel like a one-way bet on the exchange rate. A sterling Assurance Vie offers a tax efficient way to save and invest money when becoming French resident without forcing every pound through a euro conversion the day you invest it. The Assurance Vie offers tax advantages which are covered in full in our guide to Assurance Vie vs Life Insurance.

French contracts are euro-only

A standard Assurance Vie sold by a French insurer — AXA, Generali, a French bank's in-house contract — is, in practice, denominated in euros. There's no legal rule in the Code des assurances forcing this, but French insurers essentially never offer a sterling share class or GBP fund option on their standard contracts — it simply isn't a feature they build for. So what are your options? Here are two alternatives:

Route 1: A Luxembourg-domiciled contract

Luxembourg insurers offer Assurance Vie contracts that are genuinely multi-currency by design — you can denominate the contract itself in euros, sterling, US dollars, or Swiss francs, and hold funds inside it in that currency. This is a real structural feature of the Luxembourg product, not a workaround: Luxembourg contracts are built from the outset to serve an international client base who don't want their savings forced into euros.

For French tax purposes, a Luxembourg Assurance Vie is treated the same as a French one — same wrapper, same 8-year rule, same withdrawal and succession tax treatment. The difference is entirely about currency flexibility, provider protection, and how the contract is administered, not about the tax rules that apply to it.

What's genuinely different about the Luxembourg version:

• Policyholder protection is stronger. French contracts are protected by the FGAP (Fonds de Garantie des Assurances de Personnes) up to €70,000 per policyholder, per insurer, if the insurer fails — doubling to €140,000 for a contract co-subscribed by two people, such as spouses, and rising to €90,000 for death or incapacity annuities. Luxembourg's system — known as the triangle de sécurité — works differently: it separates policyholder assets from the insurer's own assets from the outset, under regulatory oversight, and grants policyholders "super-privilege" first-rank creditor status if the insurer does fail. In practice this means the full value of the contract is protected, not capped at a fixed ceiling — though it protects against the insurer failing, not against ordinary investment losses from how the underlying funds perform.
• The paperwork can be in English. Many Luxembourg providers offer contract documentation and correspondence in English, rather than exclusively in French.
• Minimum investment is typically higher. Luxembourg contracts are generally aimed at larger portfolios than a standard French contract requires — this isn't the natural home for a modest, regular savings plan.

Route 2: A UK or Irish "international bond"

The second route is a UK- or Irish-administered investment bond — Prudential International's "International Prudence Bond" is a real example — that is marketed and structured to sit inside the French Assurance Vie tax wrapper, while being administered entirely outside France.

Prudential International Assurance plc is based in Ireland and is authorised and regulated by the Central Bank of Ireland — not by a French or Luxembourg regulator. The International Prudence Bond itself has a minimum investment starting from £20,000 (or €25,000 / $35,000), with top-ups available from £15,000 — considerably more accessible than a typical Luxembourg contract, which is generally aimed at larger portfolios. Client assets are legally segregated from the insurer's own assets under Central Bank of Ireland rules, and the insurer's creditors have no claim over them — a real protection, though structured differently from both the French FGAP cap and the Luxembourg triangle de sécurité.

Important: To avoid any nasty surprises, check whether the product is genuinely accepted by the French tax authority as an Assurance Vie for the specific tax treatment you're relying on — this is generally the case for established products of this kind, but it's worth confirming with an adviser for anything less well established, rather than assuming.

Comparing the three routes

Sterling doesn't make the currency risk disappear — it moves it

It's worth highlighting what holding sterling inside the wrapper actually achieves.

If your savings are in sterling and you buy an Assurance Vie in France, you're exposed to the GBP/EUR exchange rate on the day you invest. Holding the contract in sterling avoids this specific conversion and moves the conversion to later at the point of withdrawal.

So the currency risk hasn't disappeared; it's moved from the day you invested to the day you withdrew.

So you should weigh up the pros and cons of both and use the Sterling fund as part of an overall strategy for spreading currency risk.

Tax treatment is identical either way

Whichever route you take — Luxembourg multi-currency contract, UK/Irish international bond, or a standard euro-denominated French contract — the French tax treatment of the wrapper itself doesn't change. The 8-year rule and withdrawal allowance, the gain-only taxation, and the succession allowance per beneficiary all apply the same way regardless of what currency the contract happens to be denominated in. Currency is a feature of the contract's administration, not a variable in how France taxes it.

What does change practically is how much work falls on you at declaration time. A French or Luxembourg provider transmits the IFU directly to the French tax authority — in the large majority of cases, the taxable gain is already sitting in the relevant boxes on your pre-filled online return before you even log in. Your job is to check those figures against your own copy of the IFU, not calculate them from scratch — "pre-filled" doesn't mean "correct," particularly if you hold contracts with more than one provider, so it's still worth verifying rather than assuming the figures are right.

A UK/Irish provider like Prudential isn't part of that automatic reporting system at all. Prudential International is not under the French-facing regulatory framework, so when a withdrawal is made from the policy, it will not issue a French-format tax certificate (an IFU), and nothing is transmitted to the French tax authority or pre-filled on your behalf. The gain calculation, the currency conversion, and every box entry are down to you, working from whatever documentation the provider sends — see our worked example, How to Declare a UK Prudential Assurance Vie Withdrawal, for exactly what that involves.

What if you move back to the UK before withdrawing?

Worth flagging even though it's beyond this article's scope: the tax picture changes on both sides of the Channel if you become a non-resident before you withdraw. On the French side, non-residents are taxed under a different withholding regime and lose access to the resident-only annual allowance. On the UK side, a UK/Irish bond like Prudential's is typically a "chargeable event" product, where returning to UK residence can bring a previously-untaxed gain back into scope.

This is a big enough topic — and closely tied to France's separate exit tax rules more generally — that it deserves its own dedicated article rather than a summary here. See France's Exit Tax: Do I have to pay to leave? for the full picture — including the useful fact that Assurance Vie itself is explicitly excluded from that specific tax, even though a withdrawal made around the same time is taxed as normal.

Frequently Asked Questions

Can a French Assurance Vie be held in sterling?

In practice, no. Standard French-domiciled Assurance Vie contracts are denominated in euros, and French insurers essentially never offer a sterling or multi-currency option on the contract itself. Sterling exposure requires either a Luxembourg-domiciled contract or a UK/Irish bond marketed to sit inside the Assurance Vie wrapper.

What's the difference between a Luxembourg Assurance Vie and a UK international bond that claims to work the same way?

Both let you hold sterling and both are taxed as Assurance Vie for French purposes, but they differ in regulation, policyholder protection, and paperwork. A Luxembourg contract operates under the triangle de sécurité, which separates policyholder assets and grants first-rank creditor status if the insurer fails. A UK/Irish bond's protection depends on where that specific insurer is regulated, and it generally won't issue a French-format tax certificate (IFU) the way a Luxembourg or French provider does.

Does holding my Assurance Vie in sterling protect me from currency risk?

It removes the currency risk at the point you invest, but not overall — you'll still convert to euros eventually when you actually spend the money in France, so the exchange rate risk moves to that later point rather than disappearing.

Is a Luxembourg Assurance Vie taxed differently from a French one?

No. For French tax residents, the tax treatment is identical — same 8-year rule, same withdrawal allowance, same gain-only taxation, same succession allowance per beneficiary. The difference is in currency flexibility, policyholder protection, and administration, not tax.

Does my provider have to give me a French tax certificate if my Assurance Vie is sterling-denominated?

Not necessarily. A French or Luxembourg provider will generally issue an IFU with the taxable gain calculated for you. A UK- or Irish-administered bond may not issue any French-format certificate at all, leaving you to identify the gain and the correct declaration boxes from whatever documentation the provider does send.

What happens to my policy if I move back to the UK before withdrawing?

Both sides of the tax picture change — France taxes non-residents under a different withholding regime and withdraws the resident-only annual allowance, while a UK/Irish bond can bring a previously-untaxed gain back into UK tax scope once you're UK resident again. See our dedicated guide to France's exit tax for the full picture.
