Betterment Cash Reserve
Betterment Cash Reserve holds a cash management balance with no minimum, so it suits US savers who park spending money inside a wider investing platform rather than chasing a term deal.

Pros and cons
Betterment Cash Reserve
Pros
- A deposit of $10 is the only entry barrier: no minimum balance and unlimited withdrawals once you are in.
- Cash is swept across a network of FDIC-insured program banks, with FDIC up to USD 250,000 behind the deposits.
- Licences cover the group: SEC (investment adviser), FINRA (broker-dealer, Betterment Securities) and SIPC member 51906.
Cons
- A variable rate, so the income on 3.5% can fall when the market softens.
- Built on US deposit protection, FDIC up to USD 250,000, so readers outside US gain less from it.
- Finteres advertises a wider spread at 0% to 36%, which pulls headline shoppers elsewhere.
Insignis Cash
Pros
- Deposits are covered by the FSCS, with cover stated as FSCS up to GBP 85,000.
- The headline rate of 4.4% to 4.61% sits above the 3% median across savings accounts on the site and the 3.46% median in the cash management ranking.
- Terms run 6 to 60, so you can move between easy access and fixed deposits without changing provider.
Cons
- The rate type is variable, so the 4.4% to 4.61% headline can move during a fixed term instead of being set at the start.
- Support runs on email, phone and help centre only, with no live chat for quick questions.
- Cash management is a small corner of the market at 3.8% of the brands on the site, against 75.2% for easy access, so there is less to compare.
Who each suits
Betterment Cash Reserve
Who it suits
- Readers who already hold investments with Betterment, since the adviser and brokerage licences sit in the same group.
- Anyone moving money in and out often, because the access terms allow unlimited withdrawals and no minimum balance.
- Savers who want the headline rate near the top of the cash-management field, where the median is 3.46%.
Who should look elsewhere
- Savers chasing the widest advertised range: Finteres lists 0% to 36%.
- Readers hoping to beat 3.5% elsewhere: bunq pays 3.01% and Wise 3.29%, so neither improves on it.
Insignis Cash
Who it suits
- Anyone starting small, since the minimum deposit on the cash management account is £0
- Savers who want a variable headline of 4.4% to 4.61% and the option to fix money for 6 to 60
- People who want to reach help by phone or email through email, phone and help centre
Who should look elsewhere

- Wise, at 3.29%, if a multi-currency balance suits you better than a single UK deposit account

Questions about each
Betterment Cash Reserve
What rate does Betterment Cash Reserve pay?+
Cash Reserve pays a variable rate of 3.5%, so the figure follows the market instead of being locked in. Cash is swept to a network of FDIC-insured program banks rather than held by Betterment, and the rate is set by what those banks pass on. Wise at 3.29% gives a second reading.
What does it cost to keep money in Cash Reserve?+
There is no monthly charge: the fee is $0 and the pricing model is no monthly fee. Opening the account takes a deposit of $10. The group also holds an investment adviser registration with the SEC and a broker-dealer registration with FINRA, so the running costs stay at the floor and the rate is the thing to compare.
Insignis Cash
What rate does Insignis Cash pay on deposits?+
The headline rate is 4.4% to 4.61% and it is variable, so the figure moves with the market rather than being set for the whole term. The median savings headline on the site is 3%, so this sits in the upper part of the field. Compare it against bunq at 3.01% and Wise at 3.29% before you commit.
Is my money protected if the provider stops trading?+
Deposits are covered by the FSCS, and the provider states cover as FSCS up to GBP 85,000. The FSCS is the UK scheme behind eligible deposits, so money inside the stated limit is backed by the scheme. Anything held above that limit sits with the provider rather than the scheme, which matters more for larger balances.
