Understanding Credit Spreads in Finance

In financial markets, a credit spread refers to two fundamental concepts: options trading credit spreads and fixed-income bond yield spreads. Both evaluate risk versus reward across market assets.

1. Options Credit Spreads

An options credit spread involves simultaneously selling one option and purchasing another option of the same class (calls or puts) on the same underlying asset with different strike prices. Because the option sold carries a higher premium than the option bought, a net premium credit is collected into your account upon trade execution.

• Bull Put Spread: Implemented when expecting prices to remain flat or rise. You sell a higher strike put and buy a lower strike put.
• Bear Call Spread: Implemented when expecting prices to remain flat or fall. You sell a lower strike call and buy a higher strike call.

2. Bond Yield Credit Spreads

In bond markets, a credit spread measures the difference in yield between a corporate bond and a risk-free government benchmark bond (such as US Treasuries) of matching maturity. Credit spreads are measured in basis points (bps), where 100 basis points equals 1.00% yield. Widening spreads indicate rising credit risk or economic uncertainty.
