The Guarantee That Has a Ceiling
A fixed deposit is about as safe as a savings product gets. The rate is contractual, the term is defined, and the maturity amount is known on day one.
But "guaranteed by the bank" is worth exactly as much as the bank is. And that's precisely why deposit protection schemes exist — they replace the bank's promise with a government-backed one, up to a limit.
Most people know a limit exists. Rather fewer know what theirs is, how it's applied, or the specific ways a large deposit can end up partly unprotected without anyone doing anything wrong.
The Coverage Limits
The major schemes and their per-depositor, per-institution limits:
| Region | Scheme | Limit |
|---|---|---|
| Eurozone / EU | National DGS under EU directive | €100,000 |
| UK | Financial Services Compensation Scheme | £85,000 |
| US | FDIC (banks) / NCUA (credit unions) | $250,000 |
| Canada | CDIC | CA$100,000 per category |
| Australia | Financial Claims Scheme | AU$250,000 |
These figures and their conditions change, so verify the current limit with the scheme directly before relying on a number.
Several structural points apply broadly across schemes:
Per depositor, per institution. Not per account. Three accounts at the same bank totalling €150,000 are covered to €100,000 in total, not €300,000.
Joint accounts are typically treated as split. A joint account is usually counted as each holder owning half, so a couple can often cover double the limit in a single joint account. The exact treatment varies by scheme.
Principal plus accrued interest. The limit generally applies to the total claim, which includes interest earned but not yet paid. A deposit sitting just under the limit can exceed it by maturity.
The Banking Licence Trap
This is where large depositors get caught, and it's entirely invisible from the branding.
Coverage is per banking licence, not per brand. Many banking groups operate multiple consumer-facing brands under a single licence. If you hold deposits with two brands that share a licence, you have one combined limit across both — not two.
Someone holding £85,000 with one brand and £85,000 with a sister brand under the same licence has £85,000 protected and £85,000 exposed, while believing they're fully covered.
Conversely, some groups do hold separate licences for different brands, in which case each carries its own limit.
There is no way to determine this from the marketing. You have to check the regulator's register, which publishes which brands sit under which licence. In the UK the FSCS provides a bank and brand checker for exactly this purpose; other schemes publish equivalent information.
Do this before splitting a large deposit. Spreading money across three brands that share one licence achieves nothing.
Temporary High Balances
Several schemes provide additional cover for a limited period when a large sum arrives from a defined life event — a property sale, an inheritance, an insurance payout, a redundancy settlement.
Where this exists, the additional protection is typically:
- Capped at a much higher amount than the standard limit
- Time-limited, often around six months from receipt
- Restricted to specified categories of event
- Sometimes requiring you to evidence the source when claiming
This is genuinely useful if you've just sold a house and the proceeds are sitting in one account while you buy another. It is not a permanent arrangement, and the clock starts when the money arrives, not when you notice.
Check whether your scheme offers this and what the qualifying events are, because the categories are specific rather than general.
What Isn't Covered
Deposit protection covers deposits. A number of products that look similar aren't deposits:
- Investment products — funds, bonds, shares — even when sold by a bank. These have separate and different protections.
- Structured deposits in some jurisdictions, depending on their terms.
- Deposits with entities that aren't licensed deposit-takers. Some savings apps and fintech products hold your money via a partner bank, and coverage depends on how the arrangement is structured. Read the terms.
- Foreign branches in some cases, where the applicable scheme may be that of the branch's home country rather than where you're resident.
- Cryptocurrency holdings — never covered by deposit protection schemes.
The distinction between "a bank sold me this" and "this is a deposit at a bank" matters enormously and is often blurred in product marketing.
Structuring a Large Deposit
If you're placing an amount above the limit, the options are straightforward:
Split across separate licences. The simplest approach. Verify licences rather than brands.
Use joint account treatment where available. A couple may be able to hold double the limit in one joint account, depending on the scheme.
Combine with a maturity ladder. Splitting across institutions to stay within limits pairs naturally with staggering maturity dates, giving you both protection and periodic access without breaking a deposit early.
Account for interest accrual. If you deposit exactly at the limit, accrued interest pushes you over it before maturity. Leave headroom — deposit somewhat below the limit so the maturity amount stays within it.
The FD Calculator tells you what the maturity amount will be:
- Enter the principal.
- Enter the annual interest rate.
- Set the term and compounding frequency.
- Read the maturity amount and total interest.
Working backwards from the limit is the useful move. If the protection limit is €100,000 and you're placing a 3-year deposit at 3.5% compounded annually, the maturity amount from a €90,000 principal is about €99,800 — comfortably inside. A €95,000 principal matures at around €105,300, leaving over €5,000 unprotected for part of the term.
Beyond Protection: What Else to Check
Deposit insurance is one factor. A few others are worth the same attention:
Early withdrawal terms. Fixed deposits generally penalise early access, either through a reduced rate or a fee. Know what breaking the deposit costs before you need to.
Whether the rate is fixed for the full term. It usually is — that's the product — but read the terms on anything unusual.
Compounding frequency. Two deposits at the same nominal rate pay different amounts depending on whether interest compounds annually, quarterly, or at maturity. Compare the effective annual rate, not the nominal one.
Tax treatment. Interest is typically taxable, and the timing of when it's assessed varies by jurisdiction and product. This affects your real return meaningfully.
Inflation. A guaranteed nominal return is not a guaranteed real return. If the deposit pays 3% and inflation runs at 4%, the purchasing power of the money falls despite the balance rising. Fixed deposits protect capital nominally, not in real terms.
Automatic rollover terms. Some deposits roll over at maturity into a new term at the prevailing rate unless you instruct otherwise. That prevailing rate may be considerably worse than what you'd get shopping around. Set a reminder for the maturity date.
FAQ
Is the limit per account or per person? Per depositor per institution, aggregated across all their deposit accounts at that institution.
Does a joint account get double protection? Under most schemes a joint account is treated as split between holders, so each holder's share counts toward their own limit. Verify the treatment under your specific scheme.
How do I check whether two brands share a licence? Consult the regulator's or the scheme's register. Several schemes publish a searchable brand checker for this purpose.
Is accrued interest covered? Generally the limit applies to the total claim including accrued interest, which is why depositing exactly at the limit leaves you exposed by maturity.
Are investment products sold by my bank covered? Not by deposit protection. Investments fall under different schemes with different limits and different conditions.
What happens if a bank fails? Covered depositors are typically compensated within a short statutory period. The exact timeframe and process depend on the scheme.
The Takeaway
A fixed deposit's guarantee is only as good as the institution behind it, which is what deposit protection is for — but the limit is per licence, includes accrued interest, and doesn't cover several things that are sold alongside deposits. Check the licence, leave headroom for interest, and confirm the current limit with the scheme rather than relying on a figure you read somewhere.
