Cash, Bonds and Stability

Stable assets exist to fund near-term needs and to reduce the volatility you must endure.

What you'll learn

  • Explain what cash equivalents such as money market funds are for
  • Describe how bonds work and what can make them lose value
  • Understand their role in a plan

Optional supplemental lesson. It doesn't count toward the certificate. Suggested after Lesson 1.1: Saving vs. Investing.

Back to Lesson 1.1

Cash equivalents

Savings accounts, money market funds and short-term treasury instruments prioritise stability and access. They are the right home for emergency reserves and short-horizon money.

Bonds

A bond is a loan to a government or company that pays interest and returns principal at maturity. Two main risks: the borrower may not pay (credit risk), and bond prices fall when interest rates rise (interest-rate risk).

Longer maturities are more sensitive to rate changes; lower-quality borrowers pay more interest for a reason.

Their role

Stable assets rarely drive long-term growth. Their job is to make the plan survivable — funding needs without forcing you to sell growth assets during a decline.

Why this matters

Having stable money available is what lets you leave long-term money invested.
