eToro Cash ISA Review 2026: Highest Rate at 4.48%

eToro has launched a Cash ISA offering 4.48% AER, the highest rate currently available in the UK market. This puts it ahead of competitors like Plum, Trading 212, and Moneybox. For a full comparison, see our Best Cash ISAs UK guide.

The eToro Cash ISA is delivered through a partnership with Moneyfarm, using Qualifying Money Market Funds (QMMFs) rather than traditional cash deposits. This structure allows for the higher rate while still providing FSCS protection.

The boosted rate promotion runs until April 30th, 2026. In this review, we cover everything you need to know: how the rate works, the terms to be aware of, and whether it makes sense for your savings.

How the 4.48% Rate Works

The headline 4.48% AER consists of two parts:

• Base rate: Variable AER linked to the underlying Qualifying Money Market Fund
• Bonus rate: 0.80% AER fixed boost for 12 months

The bonus is calculated daily on your balance. The interest accrued from the boosted rate is paid as a lump sum no later than the month following the anniversary of your first deposit.

To qualify for and keep the boosted rate, you must:

• Be a new Moneyfarm customer (never previously held a funded account with Moneyfarm)
• Be a UK tax resident (Great Britain and Northern Ireland)
• Deposit at least £500, or initiate a transfer of at least £15,000
• Maintain a minimum balance of £500 for 12 months
• Make no more than three withdrawals in the first 12 months

If your balance falls below £500 at any time, or you make more than three withdrawals during the 12-month period, the boosted rate will be forfeited.

After the 12-month boost period ends, your account reverts to the prevailing standard variable rate.

How eToro's Cash ISA Actually Works

Unlike traditional Cash ISAs where your money sits in a savings account, eToro's Cash ISA invests your funds in Qualifying Money Market Funds (QMMFs) through their partner Moneyfarm.

QMMFs are low-risk investments that hold short-term, high-quality debt instruments. They are designed to provide stability while generating returns that track interest rates closely. This is why eToro can offer rates higher than most traditional banks.

The practical difference for you:

• FSCS protection: £85,000 (investment protection) rather than £120,000 (cash deposit protection)
• Your money is segregated: Neither eToro nor Moneyfarm can access your funds
• Interest calculation: Based on QMMF performance, though presented as an AER

The QMMF structure is regulated and well-established. Your assets are held separately from eToro and Moneyfarm's own finances, meaning if either company were to fail, your money would be protected.

Who Should Consider eToro's Cash ISA

The eToro Cash ISA suits savers who:

• Want the highest available rate: At 4.48%, it currently beats all other Cash ISA providers
• Have at least £500 to deposit: Or are transferring at least £15,000 from an existing ISA
• Do not need frequent access: The three-withdrawal limit means this is better for savings you plan to leave untouched
• Are new to Moneyfarm: The boosted rate is only available to customers who have never previously held a funded Moneyfarm account

It may be less suitable if you need regular access to your funds, have an existing Moneyfarm account, or prefer traditional FSCS cash deposit protection of £120,000.

Important Terms to Know

Offer period. The boosted rate promotion runs from October 22nd, 2025 until April 30th, 2026. You must make your first deposit or initiate a transfer during this period to qualify.

New customers only. The boosted rate is exclusively available to new Moneyfarm customers. If you have previously held a funded portfolio with Moneyfarm or a funded eToro ISA Account, you will not qualify for the bonus.

The bonus rate requires commitment. If your balance falls below £500 at any time, or you make more than three withdrawals during the first 12 months, the boosted rate will be forfeited entirely.

Bonus interest payment. The 0.80% boost is calculated daily on your balance but paid as a lump sum no later than the month following the anniversary of your first deposit. It is not paid monthly.

Variable base rate. The underlying AER is linked to Qualifying Money Market Fund performance. If the base rate changes during your 12-month boost period, your total rate will adjust accordingly. You can check the current rate at etoro.com/investing/cash-isa.

ISA transfer rules. If you transfer an existing ISA to eToro, the transfer must be at least £15,000 to qualify for the boosted rate. Transfers initiated before the offer end date and received within one calendar month will still be eligible.

Annual ISA allowance. You can deposit up to £20,000 across all ISAs in the 2025/26 tax year (ending 5 April 2026). From April 2027, this allowance drops to £12,000 for most people, with over-65s retaining the £20,000 limit.

Frequently Asked Questions

Is the eToro Cash ISA safe?

Yes. Your funds are held in Qualifying Money Market Funds which are segregated from eToro and Moneyfarm's own assets. The account is covered by FSCS investment protection up to £85,000 per person.

Can I withdraw my money at any time?

Yes, the eToro Cash ISA is flexible, meaning you can withdraw and redeposit within the same tax year without affecting your ISA allowance. However, making more than three withdrawals in the first 12 months will cause you to lose the boosted rate.

When will I receive the bonus interest?

The bonus interest (0.80%) is calculated daily on your balance but paid as a lump sum no later than the month following the anniversary of your first deposit. It is not paid monthly.

Can I transfer my existing Cash ISA to eToro?

Yes, eToro accepts ISA transfers. To qualify for the boosted rate, your transfer must be at least £15,000. Transfers must be initiated before April 30th, 2026 and arrive within one calendar month of the offer end date.

Why is FSCS protection only £85,000 instead of £120,000?

Because the Cash ISA uses QMMFs (investments) rather than traditional cash deposits, it falls under FSCS investment protection (£85,000) rather than deposit protection (£120,000). The underlying funds are still segregated and low-risk.

Do I need an existing eToro account?

You will need to create an eToro account to access the Cash ISA. However, you must be a new Moneyfarm customer to qualify for the boosted rate. If you have previously held a funded Moneyfarm account, you will not be eligible for the bonus.

What happens if my balance falls below £500?

If your balance falls below £500 at any time during the first 12 months, you will forfeit the boosted rate entirely. The same applies if you make more than three withdrawals during this period.

Risk Disclaimer: As with all investing, your capital is at risk. The value of your portfolio with Moneyfarm can go down as well as up and you may get back less than you invest. Tax treatment depends on individual circumstances and may change in the future.
