Before you choose
- Bank-group membership is not proof of a shared core banking engine or simultaneous failure.
- Different institutions and Visa plus Mastercard add diversity, but can still share processors, telecoms and other infrastructure.
- UK deposit protection and US FDIC insurance address eligible deposit losses, not instant access during an outage.
- A brokerage cash-management service is not identical to a bank account. Identify sweep banks, card issuers and access conditions.
US institution map
Group membership does not establish a shared IT platform. Check the legal institution and your actual card scheme. For credit unions check NCUA; for brokerage cash check underlying sweep banks.
