Credit Trading¶
Difficulty expert
Overview¶
Credit trading involves buying and selling debt instruments and credit derivatives to profit from changes in credit quality and spreads.
Credit Instruments¶
Bonds¶
| Type | Description | Risk |
|---|---|---|
| Investment Grade | BBB-/Baa3 and above | Low-Medium |
| High Yield (Junk) | Below investment grade | High |
| Distressed | Near or in default | Very High |
| Convertible | Bond + equity option | Medium |
Credit Derivatives¶
| Instrument | Description | Use |
|---|---|---|
| CDS (Credit Default Swap) | Insurance against default | Hedge/speculate on credit |
| CDO (Collateralized Debt Obligation) | Pooled credit risk | Tranche exposure |
| TRS (Total Return Swap) | Exchange total returns | Synthetic exposure |
| CLN (Credit Linked Note) | Bond + embedded CDS | Credit exposure |
Credit Spread¶
Credit Spread = Bond Yield - Risk-Free Rate
Compensates investor for:
- Default risk
- Liquidity risk
- Recovery uncertainty
where:
Bond YieldYTM on the corporate (or sovereign) bond ·Risk-Free RateYTM on the matching-tenor Treasury. does: the premium investors demand for taking credit risk. Used as the headline credit-quality signal — widening spreads price in higher expected default; tightening spreads imply improving credit conditions. Core observable for credit-spread mean-reversion and capital-structure arb.
Credit Default Swaps (CDS)¶
Mechanics¶
Protection Buyer:
- Pays periodic premium (spread × notional)
- Receives payment if credit event occurs
Protection Seller:
- Receives premium payments
- Pays if credit event occurs
Credit Events:
- Bankruptcy
- Failure to pay
- Restructuring
CDS Pricing¶
CDS Spread ≈ (1 - Recovery Rate) × Default Probability
Upfront Payment = PV(Protection Leg) - PV(Premium Leg)
where:
CDS Spreadannual premium paid by protection buyer (bps) ·Recovery Rateexpected payout share if default occurs ·Default Probabilityannualized default hazard ·Upfront Paymentsettled today when running spread differs from contract coupon ·PV(...)discounted present value. does: the first-order pricing identity for a vanilla CDS — spread reflects loss-given-default times default probability. Used to imply default probabilities from market spreads (and vice versa) and to back-solve recovery assumptions implicit in trading levels.
Credit Strategies¶
Spread Compression¶
Buy protection when spreads are tight
Sell protection when spreads are wide
Profit from mean reversion in credit spreads
Capital Structure Arbitrage¶
Curve Trading¶
Same issuer, different maturities
Bull steepener: Short short-dated, long long-dated
Bear flattener: Long short-dated, short long-dated
Risk Factors¶
| Risk | Description | Mitigation |
|---|---|---|
| Default Risk | Issuer defaults | Diversification, credit analysis |
| Spread Risk | Spreads widen | Hedging with CDS |
| Liquidity Risk | Can't exit position | Trade liquid names |
| Recovery Risk | Unknown recovery amount | Conservative recovery assumptions |
| Counterparty Risk | CDS counterparty defaults | Use clearinghouse |
Practical Guidelines¶
- Credit Cycle Matters — Spreads widen in downturns
- Recovery Rates — Critical for pricing credit risk
- Liquidity Varies — IG liquid, HY less so
- Correlation Risk — Credits correlate in crises
- Documentation — ISDA agreements govern derivatives
- Rating Agencies — Don't blindly trust ratings
- Mark-to-Market — Credit positions can be hard to value
