Risk versus return

Fixed income is often called "safe", but that word hides important distinctions. Every instrument carries some mix of risks, and the return you are offered is the market’s price for taking them on.

The main risks to weigh

• Credit (default) risk — the chance the issuer fails to pay you back. A government bond carries the lowest credit risk in its own currency; a small company’s debt carries much more, and pays more to compensate.
• Interest-rate (market) risk — even a safe bond changes in value before maturity as rates move. We cover this directly in the lesson on mark-to-market.
• Liquidity risk — how easily you can turn the investment back into cash before maturity, and at what cost. Some instruments let you exit any business day; others lock your money for years.
• Inflation risk — the danger that rising prices erode the real value of a fixed return. An inflation-linked bond defends against this; a prefixed one does not.

The core trade-off

Higher promised returns almost always mean higher risk somewhere. If one instrument pays far more than a comparable one, the difference is rarely a free lunch — it is usually paying you for extra credit risk, a longer lock-up, or weaker guarantees.

A practical lens

A useful habit is to ask three questions of any fixed-income offer:

1. Who is the borrower, and how likely are they to pay me back?
2. When do I get my money, and what does it cost to leave early?
3. Is the return fixed, floating, or inflation-linked — and does that match my goal?

The rest of this track gives you the tools to answer all three for the products Brazilians actually use.
