How does the positioning of a debt instrument in the capital structure affect its risk and cost of capital?

The positioning of a debt instrument in the capital structure significantly influences both its risk and its cost of capital due to the hierarchy of claims in the event of liquidation or bankruptcy.

When a debt instrument occupies a higher position, often referred to as “senior debt,” it holds a more secure claim on the company’s assets and earnings. This seniority means that, in the event of liquidation, holders of senior debt are repaid before those holding subordinated or junior debt. Because of this reduced risk associated with senior debt—it is less likely to incur losses during adverse events—the interest rate, or cost of capital, is typically lower compared to lower-ranked debt instruments.

Consequently, the correct understanding is that higher-positioned debt instruments are characterized by lower risk due to their priority in the capital structure and, importantly, lower costs as investors demand less yield for taking on less risk.

In contrast to the correct answer, options that suggest higher risk or higher costs for higher-positioned debt fail to recognize the fundamental principles of risk-return trade-off in finance. Also, the idea that lower-position debt could equate to lower cost overlooks the correlation between risk and required return—investors demand higher returns for assuming greater risk. Furthermore, the assertion that positioning
