In the world of financial derivatives, particularly options, the concepts of credit exposure and credit risk often get muddled. While they are interconnected, they represent distinct aspects of the relationship between the buyer and seller of an option contract. Let’s unravel these concepts and explore them with examples that bring clarity.

Credit Risk vs. Credit Exposure: The Basics

• Credit Risk is the likelihood of financial loss due to a counterparty’s failure to fulfill its contractual obligation. In simple terms, it’s the possibility that the party you’re dealing with won’t pay up when they’re supposed to.
• Credit Exposure is the amount of money at stake if the counterparty defaults. It measures how much you stand to lose in dollar terms.

The Buyer-Seller Dynamic in Options

In an option contract, two parties enter into an agreement: the buyer, who pays a premium for the right (but not the obligation) to exercise the option, and the seller (or writer), who collects the premium and assumes the obligation to deliver the payoff if the buyer exercises the option.

1. The Seller’s Perspective:
   • The seller has no credit exposure because they receive the premium upfront. Regardless of what happens with the option, the seller is financially secure with the premium in their pocket.
   • However, the seller carries a performance obligation. If the buyer exercises the option and it’s in-the-money (profitable for the buyer), the seller must deliver the underlying asset or cash.

2. The Buyer’s Perspective:
   • The buyer has credit exposure. If the seller fails to deliver the underlying asset or cash when the option is exercised, the buyer loses the intrinsic value of the in-the-money option.
   • In short, the buyer depends on the seller’s ability to fulfill the contract, which is where the buyer’s credit risk comes into play.

Example: 

Imagine Sarah purchases a call option from John to buy 100 shares of XYZ Corp at $50 per share. Sarah pays John a premium of $200 for this option. Now, suppose XYZ Corp’s stock price rises to $70, making Sarah’s option $20 in-the-money per share.

The Buyer’s Credit Exposure

• Sarah decides to exercise her option, expecting John to deliver 100 shares at the agreed-upon $50 price.
• John’s obligation is to either deliver the shares or pay Sarah the $20 per share profit ($2,000 total).
• If John defaults or cannot fulfill this obligation, Sarah’s credit exposure is $2,000, representing the value she stands to lose.

The Seller’s Position

Let’s flip the script. John, as the seller, received $200 from Sarah upfront as the option premium. If the option expires out-of-the-money (say, the stock price remains below $50), John keeps the $200 without further obligations.

• Even if Sarah exercises an in-the-money option, John has no credit exposure since his role is to fulfill the obligation. His only “risk” is operational, not financial.

Why This Matters in Real Life

The distinction between credit exposure and credit risk is critical for risk management, especially in OTC markets where direct counterparty relationships dominate. Buyers must assess a seller’s creditworthiness before entering a contract. On the other hand, sellers focus more on market risks, as their credit exposure is negligible.

Takeaway

In the dance of options trading, the buyer always bears the credit exposure, while the seller’s primary concern is fulfilling their obligation. This asymmetry highlights the importance of clear risk assessment and mitigation strategies, especially in non-standardized derivative markets.

So, the next time you think about options, remember: the buyer has more to lose if things go south, while the seller just needs to keep their promise. Understanding these roles not only improves your grasp of derivatives but also equips you to navigate financial risks with confidence.
