Public debt refers to the total amount of money owed by a government to creditors, individuals, institutions, or foreign governments. It’s the accumulation of borrowing by the government over time through issuing bonds, treasury bills, and other securities to finance its expenditures when its revenues are insufficient to cover its expenses.

(v) Credit Rating and Investor Confidence: High levels of debt can negatively impact a country’s credit rating, making it more expensive for the government to borrow money.
