Bondholders may face some disadvantages with sinking funds. One of the risks is that payments from the sinking funds might not be enough to cover the rising cost of debt servicing over time. In addition, the lack of liquidity may make it difficult for a firm to meet its obligations. Bondholders would be left in an uncertain situation if they were unable pay their bond.
Bondholders can still benefit from bonds, even though they are riskier than traditional debt instruments such as loans. This is because bondholders get a higher interest rate in exchange for the longer maturity period and more security with repayment terms. How each party will view sinking funds depends on the level of risk they are willing to take and their current financial situation.
