Executing the Carry Trade with Single-Name CDS

The CDS Carry Trade: Monetizing the Spread Differential

A CDS carry trade is a strategy that seeks to profit from the difference between the credit spread on a reference entity and the cost of financing the position. In its simplest form, a positive carry trade involves selling protection on a company (going long credit risk) and earning the CDS premium, while financing the position at a rate lower than the premium received. This generates a positive carry, or net income, over the life of the trade, assuming no credit event occurs.

Anatomy of the Trade

The fundamental components of a single-name CDS carry trade are:

• Selling Protection: The trader sells a CDS on a specific reference entity. This means they are obligated to make a payment to the buyer if a credit event (such as bankruptcy or failure to pay) occurs. In return, the seller receives regular premium payments.
• Financing: The trader must have sufficient capital to cover the potential loss in case of a credit event. The cost of this capital, or the financing cost, is a key determinant of the trade's profitability.
• Spread Differential: The profitability of the trade hinges on the spread differential: the difference between the CDS premium received and the financing cost. A positive spread differential results in a positive carry.

Positive vs. Negative Carry

• Positive Carry: A positive carry trade is established when the CDS premium is higher than the financing cost. The trader profits as long as the reference entity does not default. For example, if a trader sells a 5-year CDS on a company with a spread of 200 basis points and their financing cost is 50 basis points, they earn a positive carry of 150 basis points per year.

• Negative Carry: A negative carry trade occurs when the CDS premium is lower than the financing cost. This type of trade is typically entered into with the expectation that the credit spread will tighten (decrease). The trader would buy protection, paying the CDS premium, and hope to sell it back at a lower spread, thus making a capital gain that outweighs the negative carry.

Practical Example: A Positive Carry Trade

Consider a hedge fund that wants to execute a positive carry trade on a high-yield corporate bond issuer.

1. Trade Selection: The fund identifies a company with a 5-year CDS spread of 400 basis points that they believe is fundamentally sound and unlikely to default in the near term.

2. Execution: The fund sells $20 million of protection on this company, receiving an annual premium of $800,000 (4% of $20 million).

3. Financing: The fund's prime broker provides financing at a rate of 100 basis points. The annual financing cost is $200,000 (1% of $20 million).

4. Profit Calculation: The net annual carry is $600,000 ($800,000 - $200,000), or 300 basis points.

Risks and Considerations

While the CDS carry trade can be profitable, it is not without risks:

• Credit Risk: The most significant risk is that the reference entity defaults. In this scenario, the protection seller would have to make a large payment to the buyer, potentially wiping out all the carry earned and resulting in a substantial loss.
• Spread Widening: If the credit spread of the reference entity widens, the mark-to-market value of the CDS position will decrease. This can lead to margin calls and potential losses if the position is closed before maturity.
• Liquidity Risk: The CDS market can be illiquid at times, making it difficult to exit a position at a favorable price.
• Financing Risk: A sudden increase in financing costs could erode or eliminate the positive carry.

Conclusion

The CDS carry trade is a popular strategy among credit-focused hedge funds and proprietary trading desks. It offers a way to generate income by monetizing the spread differential between CDS premiums and financing costs. However, it is a leveraged trade that carries significant risks, and a thorough understanding of the underlying credit and market dynamics is important for success.
