Regulated partner banks
provide a secure foundation
Mercury isn’t technically a bank —but you’d never know it.
Working with regulated partner banks allows us to unlock secure access to the U.S. banking system and focus on building innovative products for over 200K startups.
But like you, we’re thoughtful about who we do business with.
When selecting a partner bank, here’s what we look for:
- Institutions that are U.S.‑based and federally regulated
- Strong financial health — think robust capital ratios, stable assets, and a track record for profitability
- Diverse deposit sources and a wide range of customer industries
- A shared belief in our ambitious product goals and the determination to help us reach them
We primarily work with three partner banks:
- Choice Financial Group, Column N.A., and Evolve Bank & Trust provide banking services that include storing your checking and savings deposits via a sweep network of reputable, FDIC‑insured banks.
- Patriot Bank backs our credit card.*
In the case of Mercury Treasury, we work with Apex Clearing Corp, a FINRA‑regulated brokerage firm subject to similarly rigorous requirements as our partner banks. Mercury Treasury accounts, which allow customers to earn yield** through Morgan Stanley and Vanguard mutual funds, are insured by the SIPC rather than the FDIC.
It all starts with building a bank account
From start to finish, your Mercury experience is crafted around a bank account, the ultimate source of truth for your company’s finances.
And to give you the best possible banking experience, we’ve preserved the finest elements of traditional banking — and cut out the worst.
You get stability and security through strategically chosen partner banks that support a range of industries and are less sensitive to the volatility of the startup ecosystem.
You’re spared from unwieldy interfaces and hidden fees because we’ve designed a banking experience that respects your startup’s time and resources.
From start to finish, your Mercury experience is crafted around a bank account, the ultimate source of truth for your company’s finances.
How your FDIC protection is 20x the per bank limit
A sweep network is a program that involves strategically spreading deposits across multiple banks, reducing the impact of any single point of failure. Customers gain access to expanded FDIC insurance coverage without having to interact with more than one bank.
Our partner banks, Choice, Column, and Evolve, each participate in their own sweep networks that include several trusted, FDIC-insured banks — all of which can be found in the Choice Documents, Column Documents, and Evolve Documents on our Legal page.
Thanks to this program, your Mercury checking and savings deposits are eligible for up to $5M1 in FDIC insurance coverage — 20x the standard per bank limit.
To diversify your deposits, you can use Mercury Treasury to allocate any of your excess funds — for example, beyond the FDIC‑insured $5M — into mutual funds that are invested in short-term securities.

Modern payments
infrastructure reduces friction
Banking is complex.
But your experience with it
doesn’t have to be.
One of the primary functions of banking is to send money.
Every time you wire a payment or deposit a check, that money moves between financial institutions along a network of payment rails.
Mercury has engineered smoother ways for you to send money along these payment rails — like in the case of international wires and ACH payments — by offering more transparency than traditional banks. As a bonus, we’ve even absorbed many of the hidden fees levied in the process.
To keep your transactions compliant and secure, we’ve also assembled a world-class compliance and risk team that understands banking — and startups.
A more transparent way to wire money abroad
Whenever you send a wire abroad, that money may pass through intermediary banks before reaching your recipient’s bank — which may lead to incurred fees.
As a sender, you often don’t have visibility into the process or the fees, which are typically deducted from your recipient’s final sum.
At Mercury, we’re transparent about our wiring fees.
- Domestic wires are always free to send.
- International wires in USD are free to send, and you have the option to absorb your recipient’s fees for a flat $15 so that the full amount you send is always delivered to your recipient.
- Fees incurred by non‑USD international wires are covered by our flat 1% foreign exchange rate.
Why your ACH payments are processed in-house
While most fintechs outsource ACH file processing to their partner banks, we do as much of the work in‑house as possible to reduce the chance of fraud.
Not only do we build each file to the exact specifications of our partner banks, but we also use our own compliance system as a first line of defense to properly validate your transaction.
Only then do we hand off the file to our partner banks, who use their own due diligence instruments to perform a final check on our work before making sure that money is delivered safely to its destination.
