Where are my funds kept?
Mercury works with two FDIC-insured banks, Choice Financial Group and Evolve Bank & Trust. You can locate your Mercury account’s banking provider by logging in and viewing the banking partner listed on your Mercury statements.Through each of our partner banks, Mercury customers get access to a sweep network of trusted banks. This sweep network provides up to $5M1 in FDIC insurance by automatically spreading your deposits across up to 20 different banks, without requiring you to open and manage separate bank accounts.Our Treasury* product is offered through an additional partner, Apex Clearing Corp, who is a FINRA-regulated broker-dealer.

Are my deposits FDIC-insured?
Mercury checking and savings deposits are FDIC-insured up to $5M1 through our partner banks and use of sweep networks. As a broader effort, we are working on expanding all coverage even further. You can learn more about FDIC insurance here.
What is a sweep network?
Sweep networks are a way for customer deposits to be spread across a network of banks. Sweep networks aren’t investment funds — accounts held across the network are treated similarly to money in a typical bank account.At Mercury, rather than holding deposits with a single banking partner, we give you the choice to opt in to our partner banks’ sweep programs, which then spreads your deposits across a network of established FDIC-insured program banks.For example, if the partner bank on your Mercury account is Evolve Bank & Trust and you’re opted into Evolve’s sweep program, less than 10% of your Mercury deposits are actually held at Evolve. Instead, the majority are held at across several other FDIC-insured banks in the sweep network. For a full list of banks within our partner banks’ sweep networks, you can review Evolve Documents and Choice Documents on our Legal page.
Is my Mercury Treasury account held in my name?
Your Mercury Treasury account is held in your name — and we’re able to do this through our partner, Apex Clearing Corp, a FINRA-regulated broker-dealer that has been in business for over 40 years. This means that every time a customer signs up for Mercury Treasury, we open an account in their name at Apex, which holds their funds in custody. A few other things to note about Apex:
  • They maintain a detailed record of each Treasury customer’s holdings and are prohibited from using any of these funds or securities for its own purposes — or from commingling them with its own customers’ holdings.
  • They are regulated by the SEC and FINRA.
  • They are regularly audited and must publish its financial statements to the public.
  • They are required to keep excess capital on hand to ensure customer deposits are protected.
We’ve worked with experienced regulatory counsel to set this up. Regardless of what happens to Mercury, any funds and securities held at Apex will remain safe and accessible.
How are money market funds secured?
With Mercury Vault, customers with cash over their FDIC insurance limit can protect those funds by moving them to Mercury Treasury’s Vanguard money market fund, which is 99.5% invested in US government-backed securities and held 100% in the customer’s name.Investments made in Mercury Treasury ensure that your money is protected beyond any FDIC insurance amount.Mercury Treasury accounts are held in an account in your name at our partner, Apex Clearing Corp, a FINRA-regulated broker-dealer. In the unlikely event that Mercury or its diversified network of partner banks suffers liquidity risk, your funds would be fully safeguarded at Apex. As a broker-dealer, Apex is prohibited from using customer funds or securities for its own purposes or even from commingling those funds/securities with its own. In the unlikely event that Apex were to fail, your funds would be safely transferred to another broker-dealer.
