In short: The yield curve plots government bond yields against their maturity. Its shape tells you what markets expect rates to do: upward sloping means higher rates ahead, flat means uncertainty, and inverted - short rates above long - has historically preceded slowdowns. It also sets the base for fixed home loan pricing.
Key takeaways
- The curve reflects market expectations, not predictions that always prove right.
- Fixed home loan rates are priced off swap rates that track the curve.
- Inversion has preceded recessions but with variable and long lags.
- Term premium means long rates are not simply an average of expected short rates.
Reading the shape
| Shape | What it implies |
|---|---|
| Upward sloping | Rates expected to rise; normal conditions |
| Flat | Uncertainty, or a cycle near its peak |
| Inverted | Rates expected to fall; often signals slowdown |
| Steepening | Growth or inflation expectations rising |
Why it sets your fixed rate
Lenders fund fixed-rate loans by paying fixed in the swap market. The 3-year swap rate is the base for a 3-year fixed home loan; the lender adds a margin for cost, capital and profit.
That is why fixed rates move before the RBA does. When markets expect cuts, fixed rates fall in advance - which is also why fixing after that expectation is priced in rarely captures a bargain.
Term premium
Long rates are not simply the average of expected short rates. Investors demand extra compensation for locking money away - the term premium - covering uncertainty about inflation and future policy.
This is why a 5-year fixed rate is usually above the average of expected cash rates over those five years, and why fixing longer generally costs more.
Frequently asked questions
Does an inverted curve mean a recession is coming?
It has preceded many, but the lag varies from months to years and there have been false signals. It is one indicator among several, not a forecast.
Where can I see the Australian curve?
The RBA publishes government bond yields across maturities in its statistical tables, and the ASX publishes cash rate futures showing market expectations.
Should the curve drive my fix decision?
It tells you what is already priced in, which is useful context. But fixing is a decision about wanting certainty, not about beating a market that has already priced the expectation.
