By the end
Explain the difference between the policy rate and market yields, why bond prices and yields move oppositely, and what the yield curve is actually telling you.

  • Macro +14
  • Risk +5

The policy rate is set by a committee. Every other rate in the economy is set by markets, anchored to expectations about that policy rate over time. Conflating the two is the most common source of confusion in macro commentary.

The intuition, simplified

yield ≈ annual coupon / price

A bond paying $5 a year bought at $100 yields 5%. If its price falls to $80, the same $5 is a 6.25% yield. Real bond maths accounts for maturity and reinvestment, but the inverse relationship is exactly this.

The yield curve plots yield against maturity. Normally longer maturities yield more, compensating for the additional uncertainty of lending for longer. When short yields exceed long yields the curve is inverted, which historically has often preceded recessions — though the lead time has varied enormously and there have been false signals.

Common belief

"An inverted yield curve means a recession is coming."

What is actually true

Inversion has preceded most recent recessions, but the lag has ranged from months to over two years, and there have been inversions without recession. It is a signal worth weighting, not a trigger. VILIQ treats the 10Y–2Y spread as one factor among many, not as a standalone call.

Example — What the front end is telling you

The policy rate is 4.35% and the 2Y yield is 3.60%. The market is pricing meaningful cuts over the next two years. If the 2Y then rises to 4.20% without any policy meeting occurring, expectations have shifted — the market now expects fewer cuts. Nothing was announced; the expectation changed.

This is why the VILIQ regime engine uses the policy rate, the 2Y yield and the real 10Y yield as separate inputs rather than a single "rates" number. They answer different questions, and periods where they diverge are exactly the periods worth noticing.

Glossary

Policy rate
The rate set by the central bank, which anchors short-term borrowing costs.
Yield
The return a bond provides at its current price, expressed as an annual percentage.
Yield curve
Yields plotted against maturity. Inversion means short yields exceed long yields.
Term premium
The extra yield demanded for lending over a longer horizon and bearing that uncertainty.

  1. 1.Bond prices fall. What happens to yields?
  2. 2.The 2Y yield is well below the policy rate. What is the market saying?
  3. 3.What is the accurate reading of an inverted yield curve?
  4. 4.Why does VILIQ use the policy rate, 2Y and real 10Y as separate inputs?

Challenge — Yield from a price move

A bond pays a fixed A$4 per year. Compute its approximate simple yield at prices of A$100, A$90 and A$80. Then explain in your own words why an investor who already owned the bond at A$100 has lost money even though the payments never changed.

What a good answer contains

  • Computes all three yields correctly using coupon divided by price
  • Explains that the loss is a fall in market value, not a change in payments
  • Notes that holding to maturity and selling early produce different outcomes
