With the help of a credit swap, the buyer can make regular installments to the insurance company and transfer the risk of default to the insurance company or another investor in case the debt is not paid.
Similar to an insurance policy, a CDS allows buyers to purchase protection against unfortunate events that could affect their investments.
For example: Suppose an investor buys a 30-year bond for $20,000. Long maturities add uncertainty to investors, as the company may not be able to pay the $20,000 principal or future interest before maturity.
To guarantee the likelihood of these outcomes, the investor will purchase a CDS.
A credit default swap guarantees payment of principal or interest over a predetermined period. Investors typically purchase credit default swaps from large financial institutions that guarantee their underlying debt for a fee.
