The kanji 債 is a 形声文字 (keisei moji), a phono-semantic compound. It combines two elements: ⚫︎ The radical 亻 (ninben), "person," on the left side, which acts as a semantic component, suggesting something related to human activities or relationships. ⚫︎ The phonetic component 責 (seki), which contributes the sound and also implies the meaning of "responsibility" or "blame". The original meaning of 責 is "to demand, to blame". Therefore, 債 originally represented the idea of a financial or other obligation that someone (the person radical) is responsible for, thus, the debt. The phonetic component 責 adds the nuance of obligation.
