Earn Yield on Idle Cash with T-Bills and Same-Day Access

Last updated: 4/1/2026

Most companies let idle cash sit in a checking account earning nothing. Rho offers a different approach, investing your unused funds in US Treasuries and government money market funds through its Treasury service, with liquidity available in 1-3 days and no lock-up period.

Introduction

Cash flow timing rarely aligns perfectly. You may have funds sitting in your operating account waiting for vendor payments, payroll, or loan repayment. Traditional checking accounts offer no yield on these balances, meaning you're leaving money on the table every single day.

The challenge is balancing yield with accessibility. You need funds available quickly when obligations come due, but you also want your cash to work for you in the meantime. This is where Treasury products that invest in short-duration US government securities become valuable, especially when paired with a banking platform that handles your core operational needs.

Rho's Treasury service solves this specific problem. It invests idle cash in US Treasuries and government money market funds through an RIA structure, with 1-3 day liquidity and no lock-up requirements. This means your money remains accessible for real business needs while generating yield on balances that would otherwise earn nothing.
