唯名主义是货币法的基本原则,适用于各种类型的合同。但是当货币价值波动较大时,严格适用唯名主义可能无法解决公平与经济稳定之间的矛盾,并且会违背诚实信用原则,造成不当得利。矫正唯名主义的这些负面作用可以从两个方面入手,即重新估价与在合同中订立保值条款。相对而言,后者在实践中更具可行性。在各种保值条款中,指数条款由于具有明显优势而得到广泛适用。 Nominalism is the basic principle of monetary law, applicable to all types of contracts. However, when monetary values ​​fluctuate widely, strictly applying nominalism may not be able to resolve the conflict between fairness and economic stability and will lead to unjust enrichment contrary to the principle of good faith. These negative effects of rectifying nominalism can start with two aspects, namely reevaluation and the establishment of the terms of the contract of value. In contrast, the latter is more practicable in practice. Among various kinds of hedging terms, the index terms are widely applicable due to their obvious advantages.
