Definition
A yield spread is the difference in yields between two different debt instruments, typically expressed as a percentage or in basis points (bps). Yield spreads are crucial in assessing relative risk, investment potential, and market conditions.
How Yield Spread Works
Basic Mechanism
Yield spreads are calculated by subtracting the yield of one instrument from the yield of another. This difference can reveal the relative value and risk between the two securities.
For example, if a 10-year Treasury bond offers a yield of 3% and a corporate bond of the same maturity offers 5%, the yield spread is 2% or 200 basis points.
Basis Points
Understanding basis points (bps) is essential in discussing yield spreads. One basis point is equal to 0.01%. Hence, a yield spread of 200 basis points equals 2%.
Types of Yield Spreads
Credit Spread
Credit spread measures the difference in yields between a risk-free government bond and a corporate bond. This spread helps to estimate the credit risk premium associated with the corporate bond.
Z-Spread
The zero-volatility spread or Z-spread is a constant spread added to the yield curve such that the present value of the bond’s cash flows equals its market price. It considers the shape of the yield curve.
TED Spread
The TED spread is the difference between the interest rates on interbank loans and short-term U.S. government debt. It reflects credit risk in the banking system.
Option-Adjusted Spread (OAS)
OAS measures the yield spread after adjusting for the embedded options in the bond, giving a more precise measure of the risk and return profile of bonds with callable or prepayable features.
Special Considerations
Market Sentiment
Yield spreads often widen during periods of economic uncertainty, indicating higher perceived risk. Conversely, narrower spreads suggest lower risk and stable economic conditions.
Monetary Policy
Central bank policies significantly influence yield spreads. For instance, an increase in the federal funds rate can widen yield spreads due to differing impacts on short-term versus long-term interest rates.
Historical Context
Pre-2008 Financial Crisis
Yield spreads can provide early warnings of financial instability. Before the 2008 financial crisis, widening credit spreads indicated growing concerns about credit risk in the financial system.
Post-2008 Era
Following the crisis, yield spreads were closely monitored to gauge economic recovery and the health of financial markets. Central banks’ quantitative easing measures also influenced yield spreads.
Applicability and Examples
Investment Decisions
Investors use yield spreads to assess the relative value of bonds, make comparisons between different issuers, and tailor their portfolios to their risk tolerance.
Economic Indicators
Yield spreads can also act as economic indicators, with inverted yield spreads (where short-term yields exceed long-term yields) potentially signaling a recession.
