How Offering High-Yield Corporate Checking Through Tokenization Can Protect and Grow Corporate Deposit Accounts

Cosmos joined 2,000+ financial services leaders in New York for FinovateFall 2026, one of the industry's established forums for seeing financial technology in action. Maghnus Mareneck, Co-CEO of Cosmos, Eran Barak, Chief Commercial Officer, and Adair Kelley, Senior Solutions Engineer, presented a live demo of the Cosmos Tokenization Suite’s high-yield checking account feature.

High-yield corporate checking addresses a growing challenge for commercial banks. Corporate treasurers demand fintech features like yield on idle cash, yet yield-bearing instruments often cannot provide instant liquidity, especially outside market hours. This leaves banks looking for ways to compete with fintechs who offer yield on large corporate checking balances.

Tokenized deposits can bring these requirements together through a high-yield corporate checking account, using a digital ledger that operates alongside the bank's existing core infrastructure. For corporate clients, this means earning yield while keeping operating cash liquid and available when cash-flow events occur. For banks, it creates an opportunity to retain corporate deposits, earn a spread, and improve treasury efficiency.

Why Banks Need to Combine Yield and Liquidity

Corporate clients may hold millions of dollars in checking accounts to keep funds immediately available for payments, payroll, and other day-to-day operations. These balances can exceed the FDIC insurance limit while generating little or no yield, leaving a significant amount of operating capital readily available but earning nothing for the business. Moving that capital into yield-bearing instruments can put it to work, but often at the expense of the immediate access businesses need to make payments throughout the day.

This also creates a challenge for banks. When another provider, like a fintech, offers yield while keeping funds accessible, corporate clients have a financial incentive to move deposits away from their existing bank. For banks, offering a competitive yield while preserving liquidity creates an opportunity to protect and grow valuable corporate deposit relationships.

An instant intraday repo sweep offers a way to combine yield and liquidity. Funds in the checking account are tokenized and instantly exchanged for tokenized securities to generate yield and repurchased when cash is required for a payment. The remaining balance continues earning yield.

Banks already use repo sweeps, but they traditionally occur once a day. Performing the same process throughout the day multiple times is operationally impractical on existing infrastructure, as the bank has to move between deposits and securities whenever funds enter or leave the account.

How Tokenization Enables High-Yield Corporate Checking

The Cosmos Tokenization Suite integrates with core banking systems (such as Fiserv, FIS, Jack Henry, Temenos, Hogan, and others) and connects to external rails and networks to support tokenized deposits and other digital asset use cases. The Suite runs alongside existing banking infrastructure, creating a digital-twin side core digital ledger, without requiring banks to rebuild the systems they already use.

For high-yield corporate checking, deposits and eligible securities are represented as digital assets on the side core digital ledger, mirrored from the bank's core balance sheet. This enables operationally-efficient instant intraday repo sweeps, allowing funds to move between deposits and securities throughout the day as cash-flow events occur. Corporate clients can earn yield on their operating cash while keeping funds available when they need to make payments.

For banks, this model offers three key benefits:

• Mobilize liquidity when cash-flow events occur. Instant intraday repo sweeps allow corporate operating cash to be mobilized and settled within one business day.
• Earn a spread. Banks can price each high-yield checking offer against their own treasury pool yield and keep the difference, creating a spread-earning corporate deposit product.
• Boost treasury efficiency. Tokenized Treasuries continue earning a coupon while collateralizing intraday client repo activity, supporting a spread-earning deposit product.

A Practical Use Case for Tokenized Deposits

A high-yield corporate checking account using tokenized U.S. Treasuries provides a practical example of how a high-yield corporate checking can work. When configuring the offer, a bank can define the position limit and repo rate. For example, an annualized repo rate of 2.75% and a $7.5 million position limit against a T-Bill treasury pool yielding 3.9% would result in a 115 basis point gross spread for the bank.

Once the corporate client accepts the terms and deposits funds, the Cosmos Tokenization Suite verifies sufficient collateral and exchanges the deposits for securities to enter the sweep. The balance can begin accruing yield within seconds.

When the client makes a supplier payment, the Suite executes a partial repurchase and atomically settles the cash and securities legs on the digital ledger within seconds. The required amount becomes available for the payment, while the remaining balance continues earning yield. The workflow runs alongside the bank's existing core infrastructure.

The model brings together three outcomes:

• The client retains liquidity for everyday payments while the remaining balance continues earning yield.
• The bank retains the commercial deposit relationship and offers new experiences to its clients.
• The bank earns a spread.

The Cosmos Tokenization Suite

The Cosmos Tokenization Suite provides banks with an all-in-one platform for tokenized finance. High-yield corporate checking is one application of the Suite.

The Cosmos Tokenization Suite supports 24/7 payments with finality in under three seconds, giving banks the infrastructure to settle transactions outside traditional banking hours. For cross-border payments, this can reduce interbank friction and settlement costs while improving transaction speed and certainty.

Tokenized deposits can also help banks retain and grow deposits by adding functionality to the existing banking relationship. Clients gain access to capabilities associated with digital money, such as instant settlement, programmable payments, and smart contracts, while retaining the benefits associated with bank deposits, like clear regulation, deposit insurance, and yield.

Programmability extends these capabilities into treasury and other banking services. The Suite supports applications including real-time treasury, delivery versus payment (DvP), treasury automation, and agentic commerce, allowing banks to embed rules and conditions into how money moves.
