Credit Curve Steepener: Trading CDS Spread Shape

Key Takeaways

• A steepener sells short-dated CDS protection and buys long-dated protection, sized to equal risky PV01 across both legs.
• An inverted credit curve signals acute near-term default stress; a steepener profits if the company survives and the curve normalizes.
• The trade carries positively when the short-dated spread exceeds the long-dated spread but bleeds in normal upward-sloping conditions.
• Jump-to-default risk creates a liquidity timing mismatch: the short leg triggers first if the name defaults quickly.

What It Is

A credit curve plots CDS spreads for a single reference entity across maturities, typically 1, 3, 5, 7, and 10 years. A steepener sells short-dated protection and buys long-dated protection on the same name. A flattener does the reverse.

The trade isolates the shape of the curve. The trader makes money when the spread difference between the two tenors grows, regardless of the absolute level of either spread.

The Intuition

Most investment-grade credit curves slope upward. Default risk compounds with time, so protection buyers pay more for longer coverage. When a curve inverts, meaning short-dated spreads exceed long-dated spreads, the market is signaling acute near-term stress. If the company survives the next 12 to 24 months, the thinking goes, it has access to refinancing and time to recover.

That inversion creates an opportunity. A steepener is the natural position when a trader believes the name will either default soon or survive the stress window. If the company clears the hump, short spreads collapse toward normal levels while long spreads stay anchored, and the curve re-steepens sharply.

The trade is a staple in distressed credit. Bond investors who believe a company can make it through the next year but struggle later might buy the near-dated bond and hedge with longer-dated CDS protection, effectively putting on a steepener in a different form.

How It Works

A steepener sells protection on the short-dated contract (say 3-year) and buys protection on the long-dated contract (say 10-year). Legs are scaled so they have equal spread duration, also called risky PV01. That way, a parallel shift in the whole curve produces roughly zero P&L.

Notional_short x RiskyPV01_short = Notional_long x RiskyPV01_long

Risky PV01 is the present value of 1 bp of spread times the probability the contract survives to pay each coupon. Longer tenors have higher risky PV01, so the trade uses less notional on the back leg.

The position earns carry if short spreads are higher than long spreads (inverted curve) since the trader collects premium on the short leg. It bleeds carry when the curve is upward-sloping, which is most of the time for investment-grade names.

Worked Example

Consider a speculative-grade name, XYZ Corp, where the 3-year CDS trades at 600 bps and the 10-year trades at 450 bps. The curve is inverted by 150 bps, signaling the market prices near-term default stress.

A trader believes XYZ has enough liquidity to survive the next two years. They put on a steepener: sell 10 million of 3-year protection and buy a risky-PV01-neutral amount of 10-year protection, roughly 4 million of 10-year notional assuming a PV01 ratio of 2.5 to 1.

Twelve months pass. XYZ refinances a 2025 maturity bond, removing the near-term wall. The 3-year CDS drops to 350 bps and the 10-year drops to 420 bps. The curve re-steepens to +70 bps.

The short 3-year leg gains on a 250 bp spread tightening. The long 10-year leg loses on a 30 bp tightening. Scaled by the risky PV01s, the steepener nets a profit reflecting the 220 bp shift in curve shape. If XYZ had defaulted instead, both legs would have triggered and the P&L would depend on the recovery auction.

Common Mistakes

• Trading steepeners on flat curves. A steepener needs curve tension to unwind. On an already upward-sloping investment-grade name, the expected payoff is thin and the carry bleed adds up.
• Ignoring jump-to-default risk. If the name defaults quickly, the short-dated leg triggers first and the trader owes the recovery shortfall on that notional. The long leg also pays off, but the timing mismatch can create a liquidity squeeze.
• Mis-sizing for spread convexity. Spread duration is not constant. At very high spread levels, small spread moves produce outsized P&L. Recalibrate risky PV01 when spreads move sharply.
• Confusing a steepener with a directional credit bet. A steepener is neutral to parallel curve shifts but still has exposure to the general direction of spreads because the two tenors are imperfectly correlated.
• Forgetting the roll-down. As time passes, each leg rolls down the curve toward shorter maturities. The roll-down profile can either help or hurt the position depending on curve shape.

Frequently Asked Questions

What does an inverted credit curve tell us about a company's situation? An inverted credit curve, where short-dated CDS spreads are wider than long-dated spreads, signals that the market prices the highest default probability in the near term. This typically occurs when a company faces an imminent refinancing wall, covenant violation, or other near-term crisis that investors believe could resolve, either by default or successful refinancing, within a defined window. Beyond that window, the market prices a lower conditional default probability.

How is risky PV01 different from regular DV01? Regular DV01 is the price change for a 1 basis point shift in yield and applies to risk-free bonds. Risky PV01 accounts for the probability that the CDS contract is still alive to make payments, adjusted for the credit event probability on the reference entity. For a high-spread name, the risky PV01 of a long-dated contract is much lower than for a risk-free equivalent because there is a meaningful probability the contract terminates early through a credit event.

Can a credit curve steepener be implemented using bonds instead of CDS? Yes, approximately. Buying the shorter-maturity bond and selling or shorting the longer-maturity bond from the same issuer expresses a similar view. The short-dated bond benefits more from near-term stress resolution, while the long bond has more time-weighted credit risk. However, bonds involve accrued interest, settlement mechanics, and liquidity differences that make CDS cleaner for expressing the pure spread-curve view.

What happens to a credit curve steepener if the issuer defaults? Both CDS legs trigger a credit event. The short-dated protection sold means the trader pays out on that leg (receives par and delivers defaulted bonds or cash settles). The long-dated protection bought means the trader receives on that leg. The net P&L depends on the recovery rate and the timing and notional sizes of each leg. If the positions are PV01-balanced and the recovery rate is the same for both auctions, the net cash flows approximately offset with a small residual.

What credit curve shape is most favorable for entering a steepener trade? A steeply inverted curve (short spreads far above long spreads) provides the best entry point for a steepener. The carry is positive while the curve is inverted, and the expected convergence back toward a normal upward slope is large. A mildly inverted or flat curve offers less carry cushion and a smaller expected payoff from normalization, making the trade less attractive relative to execution costs.
