Mercury works with three FDIC-insured banks, Choice Financial Group, Column N.A., 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 $5M 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. The mutual funds that you can invest in through Mercury Treasury are managed by Morgan Stanley and J.P. Morgan Asset Management.

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. The majority of your funds are held across several other FDIC-insured banks in Evolve's sweep network. For a full list of banks within our partner banks’ sweep networks, you can review Evolve Documents, Column N.A. Documents, and Choice Documents on our Legal page.

As a financial technology company, Mercury is subject to a number of regulations that are standard across the financial services industry, including know your customer (KYC) and know your business (KYB) obligations, anti-money laundering (AML) rules, and the Office of Foreign Assets Control (OFAC) sanctions. 

Likewise, our banking and service partners such as Evolve Bank & Trust, Choice Financial Group, Apex Clearing Corp, Wise, and others are subject to rules and regulations specific to their business type. We work closely with our partners to comply with applicable laws and regulations so that we can provide the best customer experience possible.

Your Mercury Treasury account is held in your name at 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:
  • It maintains a detailed record of each Treasury customer’s holdings and is prohibited from using any of these funds or securities for its own purposes — or from commingling them with its own customers’ holdings.
  • It is regulated by the SEC and FINRA.
  • It is regularly audited and must publish its financial statements to the public.
  • It is 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.

Funds invested via Mercury Treasury are protected in several ways:
  • Your Mercury Treasury account is held in your name with our partner, Apex Clearing Corp. Apex Clearing Corp maintains a detailed record of each Treasury customer’s holdings and is prohibited from using any of these funds or securities for its own purposes, and from commingling them with its own customers’ holdings. Because assets are held in your name, they remain available to be transferred to an account at another broker in any of the following events:
    • Mercury bankruptcy, financial instability, sale or acquisition
    • Apex bankruptcy, financial instability, sale or acquisition
  • Apex is regulated by the SEC and FINRA, and is regularly audited and must publish financial statements to the public. Apex is also required to keep excess capital on hand to ensure customer deposits are protected.
  • Mercury Treasury offers two mutual funds that invest in lower-risk, short-term debt securities, such as Treasury bills, municipal debt, or corporate bonds. See the fund prospectuses for details on each fund’s holdings:
  • Mercury Treasury accounts are covered by the Securities Investor Protection Corporation (SIPC) insurance. This applies in the event that assets are lost or missing from a customer’s accounts during the time a financially-troubled or failed brokerage firm is being unwound. SIPC protects $500,000 worth of securities and cash, with maximum protection for cash of $250,000 and $250,000 in investments.

SOC 2 is an intensive auditing procedure that an independent third party uses to evaluate Mercury’s security, confidentiality, and systems availability. This assessment covers everything from background checks on our personnel to evaluations of our system architecture.

Mercury is SOC 2-compliant, meaning you can have confidence in our operations and service commitments — and peace of mind that we take pride in them. If you need our SOC 2 report for your own compliance records, reach out to us at [email protected] and we’d be glad to help.

Yes, security is a top priority at Mercury. Here are some measures we take to ensure your security:
  • Require HTTPS on all pages, and use HSTS to ensure browsers only ever connect to Mercury over a secure connection.
  • Employ a third party to perform penetration testing each year to check for vulnerabilities.
  • Hash and store all passwords with the bcrypt algorithm — never as plaintext.
  • Use time-based one-time passwords for two-factor authentication. We never send authentication codes via insecure channels like SMS.
  • Encrypt our database and all uploaded images, with additional encryption for sensitive data like social security numbers.
  • Never store your debit or credit card numbers.
