本文从加密货币市场利率研究出发，探讨收益率曲线可观察的历史条件，追溯从古美索不达米亚至现代主权债务市场的制度演变，揭示标准化债务工具等关键要素的逐步形成。
AI 中文摘要
本文源于最初为研究加密货币市场利率而撰写的历史引言。在没有传统债券市场的货币中定义期限结构的困难，自然引出了一个更根本的问题：在何种历史条件下，收益率曲线才变得可观察？信贷的存在远早于现代货币，有息贷款在古美索不达米亚时期已有记载。在历史的大部分时间里，存留的证据缺乏促进按期限可靠比较利率的制度特征：标准化的债务工具、足够同质的借款人、在多种期限上的定期发行、可观察的市场价格以及流动的二级市场。我们追溯了这些条件从古美索不达米亚、希腊和罗马，经由中世纪和近代早期欧洲，到十九和二十世纪现代主权债务市场发展的逐步出现过程。
英文摘要
This text grew out of a historical introduction initially written for a study of interest rates in cryptocurrency markets. The difficulty of defining a term structure for a currency without a conventional bond market led naturally to a more fundamental question: under what historical conditions does a yield curve become observable at all? Credit existed long before modern money, and interest-bearing loans are documented as early as ancient Mesopotamia. For much of history, the surviving evidence lacks the institutional features that facilitate reliable comparisons of interest rates by maturity: standardised debt instruments, sufficiently homogeneous borrowers, regular issuance over a range of maturities, observable market prices, and liquid secondary markets. We trace the gradual emergence of these conditions from ancient Mesopotamia, Greece, and Rome, through medieval and early modern Europe, to the development of modern sovereign debt markets in the nineteenth and twentieth centuries.
