What Is Better for Conservative Savings: Treasury Bills or Money Market Funds?

Treasury Bills have regained popularity among conservative savers. And for good reason: they offer a simple way to seek returns with a relatively low perceived level of risk.

However, when the goal shifts from making a one-off investment to building a long-term savings strategy, questions arise that are more important than the interest rate offered at the next maturity.

Before going into detail, here is a quick answer:

• Are Treasury Bills a good option for saving?
  Yes, especially for investors looking to invest a specific amount for a defined period of time..
• Is there a more flexible and efficient alternative?
  It depends on your objective, but a combination of money market funds and diversified fixed income with defined maturities can provide greater flexibility, efficiency, and better risk diversification than relying on a single issuer.
• Is the difference only about returns?
  No. Liquidity, taxation, diversification, the time required to manage savings, and issuer risk also matter. Investing in a single issue is not the same as investing through funds that can diversify across hundreds of issuers.

What limitations do Treasury Bills have when used to build long-term savings?

Treasury Bills work particularly well when the objective is clear: investing a specific amount for a specific period.

But the reality of saving is often different.

Many people save every month, make additional contributions when possible, and occasionally need to withdraw only part of their money.

In this context, certain practical limitations arise: following auction schedules, managing reinvestments, meeting minimum investment amounts, and continuously deciding what to do when each bill matures.

And there is something that is often underestimated: those who use Treasury Bill issues to gradually build and maintain savings need a sufficient understanding of how the product works, its risks, its tax implications, and its operational aspects when investing directly. In addition to the time involved, it requires organisation and discipline to maintain the strategy over the years.

The alternative is often to invest through third parties, but then any additional costs must also be taken into account.

That is why, rather than choosing a product, a more useful question is often: am I building a financial planning strategy, or simply chaining together products?

What happens if interest rates change while I hold a Treasury Bill?

Imagine that today you buy tickets for a trip that will take place in a year.

Months later, you discover that you need to travel sooner… or that you will not travel after all.

You may be able to recover part of your money. You may incur costs. Or perhaps you purchased insurance that provides greater flexibility, although at a higher overall cost.

Something similar happens with a Treasury Bill.

When you buy a Treasury Bill, you accept specific conditions until maturity. If interest rates rise afterwards, you keep the yield that was originally agreed.

And if you need to recover your money before maturity, you will have to sell it in the secondary market, where the outcome may differ from what you initially expected.

At inbestMe, we prefer a broader perspective for investors who want to keep a significant portion of their wealth in conservative solutions while maintaining a reasonable degree of certainty regarding expected returns.

Our approach is based on combining two complementary tools within a broader financial planning strategy.

So far, we have examined the main differences between Treasury Bills and other conservative savings alternatives. However, when the goal is to build an efficient long-term strategy, there are still some key aspects to consider.

In Part 2, we will look at how money market funds work within a Savings Portfolio, the role that Target Portfolios can play, and why combining different tools can help improve liquidity management, tax efficiency, and expected returns.

We will publish Part 2 soon. Stay tuned.
