Pros and cons
Ally Bank
Pros
- Savings pay 3.1% at a variable rate, a little above the site median of 3%.
- Trading covers stocks, etfs and options with a commission free model and a minimum deposit of $0.
- Cash is FDIC insured (certificate 57803), and investments are covered by SIPC up to USD 500,000.
Cons
- Savings access stops at 10 limited withdrawals and transfers per statement cycle, so a large emergency fund is awkward to hold here.
- Options are the exception to commission free trading, with a charge of $0.50.
- Robo portfolios charge a management fee of 0% to 0.3% and start at $100.
Openbank
Pros
- Interest is credited monthly, and money is withdrawable at any time in full or in part, accrued interest included
- Transfers between the current and remunerated account are free and immediate, and the card runs on mastercard
- The Mastercard debit card carries a currency conversion fee of 0% with a multi-currency feature for travel
Cons
- The headline rate of 2.75% sits below the site median, which stands at 3%
- The credit card has a rewards type of none, so nothing comes back on card spending
- The robo adviser takes a management fee of 0.42% to 1.03% and needs a minimum investment of €500
Who each suits
Ally Bank
Who it suits
- US households, since the bank is headquartered in the United States and its savings pay 3.1%.
- First-time investors, who can start trading at $0 on a commission free model.
- Retirement savers, who can hold joint, IRA and Roth IRA accounts.
Who should look elsewhere
- CFI, for readers who want forex, contracts for difference or crypto: its markets are stocks, etfs and forex, against stocks, etfs and options here.
- bunq, for euro savers who prefer an account in euros, since its minimum deposit is set at €10.
- Fiesta Credito MX, for readers in Mexico who want a lender regulated by CONDUSEF rather than SEC, FINRA and FDIC.
Openbank
Who it suits
- Savers who want interest paid monthly and no fixed term
- Households that want a current account, a savings pot and a card in one app
- Travellers who want a multi-currency card
Who should look elsewhere
- Wise, if a multi-currency account with a monthly fee of £0 matters more than deposit interest
- Starling Personal Account Debit Card, which charges a monthly fee of £0, if a UK current account fits better
- Varo Believe Secured Credit Card, which has a monthly fee of $0, if building a credit record is the aim

Questions about each
Ally Bank
What does it cost to keep an account open?+
The brokerage account fee is $0 and the online savings account carries a monthly fee of $0. The inactivity fee is also $0, so an unused account is not quietly charged. The one regular trading charge is on options, at $0.50.
Is there a minimum deposit to start?+
Self-directed trading opens at a minimum deposit of $0, and Ally Bank ranks 1 of 218 brands on that measure. Automated investing is the exception, with a minimum investment of $100 before the first purchase.
Openbank
What does it cost to hold the account?+
Openbank charges a monthly fee of €0 and a credit card annual fee of €0. Transfers between the current and the remunerated account are free and immediate, and a stock trade costs €1, so everyday banking adds very little.
How much interest do I earn?+
The easy-access account pays a headline rate of 2.75%, credited monthly, and the rate type is variable. The site median stands at 3%, so the offer sits in the middle of the market rather than at either end.
