In finance, a bond is an instrument of indebtedness of the bond issuer to the holders. It is a debt security, under which the issuer owes the holders a debt and, depending on the terms of the bond, is obliged to pay them interest (the coupon) and/or to repay the principal at a later date, termed the maturity date.  Interest is usually payable at fixed intervals (semiannual, annual, sometimes monthly). Very often the bond is negotiable, i.e. the ownership of the instrument can be transferred in the secondary market. This means that once the transfer agents at the bank medallion stamp the bond on the second market the bond

A recent New York Fed study, “Key Mechanics of the U.S. Tri-Party Repo Market,” provides a primer on the issues and key mechanics that have contributed to the market’s fragility and proved an obstacle to industry reform efforts.
In the report, the authors explain how the collateral allocation and “unwind” processes pose systemic weakness and are hindering reform efforts. These problems stem in part from the intervention by dealers to allocate collateral and their reliance on intraday financing to unwind, or settle, expiring repos.
During the 2007-09 financial crisis, it became apparent that weaknesses existed in the design of the U.S. tri-party repo market that could rapidly elevate and propagate systemic risk. This article describes key mechanics of the market, focusing on two that have contributed to its weaknesses and impacted market reform efforts: the collateral allocation and “unwind” processes. The authors explain that collateral allocation in the tri-party repo market involves considerable dealer intervention, which can slow settlement processing. The length of time required to allocate collateral has in fact been a significant obstacle to market reform. Another impediment to reform is the unwind process, or the settlement of expiring and continuing repos that occurs before new ones can be settled and continuing ones can be “rewound.” The intraday funding required as a result of the unwind process creates potentially perverse dynamics that increase market fragility and financial system risk. Indeed, a reengineering of the tri-party repo settlement process to be much less reliant on intraday credit is a main goal of current market reform. The authors argue that streamlining the collateral allocation process and eliminating the time gap associated with the unwind could minimize market risk and assist in the reform efforts.
