Citi and Coinbase launch stablecoin settlement: 3.75% a year and what a trade now has to beat

Citi and Coinbase have signed an agreement on stablecoin settlement for merchants through the Spring by Citi platform. The bank acts as the bank of record, and Coinbase virtual accounts offer a reward of 3.75% a year.

Citi's scale is serious. According to Citi Services head Shahmir Khaliq, the bank's infrastructure processes $6 trillion a day and is connected to 150 million stablecoin holders.

Why this matters beyond merchants

A major bank built into stablecoin settlement is a signal that the digital dollar is becoming part of the ordinary payment system. And the reward on accounts makes the stablecoin not just a means of settlement but also a source of income.

For an arbitrage trader, the second part is what matters. As soon as idle stablecoins have a clear yield, it becomes the bar for any strategy.

What to compare a trade's return with

An arbitrage trader holds capital in stablecoins between trades. If a trade earns less than money just sitting in a rewards account, it loses to the option of doing nothing.

From what we see, many people calculate a trade's return in isolation from the alternative. Funding at 5-6% a year looks decent, but after fees and adjusted for risk it can turn out to be almost equal to the risk-free option.

How to calculate it properly

Subtract the idle yield from the trade's return. In our view, the honest measure of a strategy is not its absolute percentage but the excess over what the capital would have earned on its own.

We believe that at these stablecoin rates, trades on a thin skew lose their point. It makes sense to work where the excess after all costs is noticeable, not where it gets eaten by fees and risk.

Our tools

The real return of a trade after fees and slippage is better calculated in advance rather than by eye. Our arbitrage screener keeps dozens of venues in one window, refreshes quotes every second and shows each gap together with the volume actually behind it. The spread calculator helps you check what survives fees, network costs and slippage at your size. The bot is fully manual. It never connects to your exchange API keys.
