How Businesses Can Earn More on Surplus Cash

Intro

Many businesses work hard to improve margins, cut costs, and manage working capital, yet still leave large cash balances sitting in accounts that do very little.

That is a missed treasury opportunity.

If your business regularly holds surplus cash, even for short periods, the question is not only where to keep it safe. The question is whether that cash is working as hard as it should.

Why surplus cash often goes unmanaged

In many businesses, idle cash is not ignored on purpose. It just falls between teams.

Finance is focused on liquidity. Operations are focused on delivery. Leadership is focused on growth. As a result, cash often ends up sitting in a current account because it feels convenient.

Convenient, however, does not always mean efficient.

The cost of leaving business cash idle

When cash sits in a low-yield account, the business loses an opportunity to earn more without taking on unnecessary complexity.

For companies that routinely hold reserves for payroll, tax, capex, imports, or buffers, the opportunity cost can be meaningful.

What businesses should look for instead

An effective short-term cash solution should offer three things:

1. Liquidity

The business must be able to access funds when needed.

2. Capital stability

Cash reserves should not be exposed to unnecessary volatility.

3. Better yield than a passive current account balance

Short-term cash should contribute to treasury performance, not just sit unused.

Why money market funds are worth considering

Money market funds are often well suited to surplus business cash because they are built for short-term liquidity and capital preservation.

They can help companies make better use of cash that may be needed soon, but not necessarily today.

Common business use cases

A money market fund may be suitable for:

• operational cash buffers
• tax provisions
• payroll reserves
• acquisition or capex funds waiting to be deployed
• seasonal cash build-ups
• temporary excess liquidity after a large receipt

A smarter treasury habit

The strongest treasury teams treat cash as an asset class, not just a leftover balance.

That means segmenting cash by purpose:

• immediate operating cash
• short-term reserve cash
• longer-dated strategic cash

Not all of it belongs in the same place.

Final thoughts

If your business is holding surplus cash, the goal is not to chase risk. It is to improve efficiency.

A money market fund can be a practical way to earn more on short-term balances while keeping funds accessible.

For many businesses, that makes it a better option than leaving large balances idle in a traditional bank account.
