期限差价（也称为利差）代表长期利率与债券等债务工具的短期利率之间的差额。为了理解期限差价的重要性，我们必须先了解债券。期限差价最常用于比较和评估两种债券，即政府，公司，公用事业和其他大型实体发行的固定利息金融资产。债券是固定收益证券，投资者通过该证券基本上在规定的时间内贷款发行人资本，以换取偿还原始票据金额加利息的承诺。这些债券的所有者成为发行实体的债权人或债权人，因为实体发行债券作为筹集资金或为特殊项目融资的手段。个人债券通常以面值发行，通常为100美元或1,000美元面值。这构成了债券本金。当债券发行时，它们会获得一个反映当时主要利率环境的既定利率或息票。该优惠券反映了发行实体除偿还债券本金或到期时借入的原始金额外，还有义务向其债券持有人支付的利息。与任何贷款或债务工具一样，债券也会在到期日或合约要求全额偿还债券持有人的日期发行。

The term difference (also known as spread) represents the difference between the long-term interest rate and the short-term interest rate of a debt instrument such as a bond. In order to understand the importance of the price difference, we must first understand the bond. The term spread is most commonly used to compare and evaluate two bonds, namely fixed-interest financial assets issued by governments, companies, utilities and other large entities. A bond is a fixed-income security through which an investor basically borrows the issuer’s capital within a specified period of time in exchange for a promise to repay the original note amount plus interest. The owners of these bonds become creditors or creditors of the issuer because the entity issues bonds as a means of raising funds or financing special projects. Personal bonds are usually issued at face value, usually at a face value of $100 or $1,000. This constitutes the bond principal. When the bonds are issued, they receive an established interest rate or coupon that reflects the prevailing interest rate environment at the time. The coupon reflects the additional interest paid by the issuing entity in addition to repaying the principal of the bond or borrowing at maturity, as well as the interest paid to its bondholders. As with any loan or debt instrument, the bond will also be issued on the maturity date or on the date the contract requires full repayment of the bondholder.
