Notching refers to the practice where credit rating agencies assign different credit ratings to the particular obligations of a single issuing entity or assign differing credits to entities that are linked to each other. This disparity may arise due to differences in seniority, payment guarantees, or revenue streams. The term is used primarily in structured finance to differentiate credit risk within a single issuer.


The phonetic spelling of “Notching” is: /ˈnɒtʃɪŋ/.

  1. Notching refers to a specific process used in meta-working, woodworking, and construction fields, where a part of the material is cut out (or ‘notched’) to enable it to fit or interlock with another piece.
  2. ‘V-Notching’ and ‘U-Notching’ are common types of notching, named due to the shape of the cut. The type of notch used usually depends on the specific requirements of the project.
  3. Notching is important because it often leads to a more sturdy and stable structure, prevents material wastage, and enhances the aesthetic appeal of the end result.



Notching is a crucial concept in business and finance because it refers to the practice of rating a specific obligation of an entity at a different, typically lower, level than the credit rating of the entity itself. This commonly occurs when the possibility of loss to the holders of the obligation is greater than the general credit risk of the institution. It affects both the perceived risk and potential value of corporate and sovereign debts, bonds, and other debt instruments. Understanding notching is essential for investors, as it will significantly influence their investment decisions and strategies. Notching ensures a more precise evaluation of the credit risk associated with an investment.


Notching serves as a critical tool in the realm of financial risk assessment and credit rating, providing an essential method for distinguishing varying degrees of risk within a single organization or structured finance deal. The process involves assigning different credit ratings to the diverse obligations of a company or to the various tranches of a structured finance security. Generally speaking, it helps in capturing differential risk among these obligations or tranches, thus aiding investors, lenders, and other stakeholders in making informed decisions.In the context of a company’s debts, notching can be seen when some bonds issued by the same company are rated higher or lower than others. This discrepancy arises from the varying levels of collateral, seniority, or other credit enhancements associated with each debt instrument. For structured finance securities like mortgage-backed securities or collateralized debt obligations, notching is used to distinguish the creditworthiness of each tranche, with senior tranches often being assigned the highest ratings due to their priority in the payment waterfall. The use of notching thus allows the market to suitably price these securities according to their inherent risk, ensuring effective risk management and prudent investment practices.


1. Credit Rating Agencies: Credit rating agencies such as Moody’s, Fitch, or S&P often employ notching to determine the creditworthiness of different types of securities issued by a company. For instance, if a firm is issuing both senior and subordinate bonds, the credit rating agency might notch down, or lower, the rating of the subordinate bonds due to their higher risk compared to the senior bonds. 2. Insurance Industry: In the insurance industry, notching might be used to adjust premium rates based on risk factors. For example, an auto insurer might notch up the premium for a driver with a history of accidents or traffic violations, reflecting the greater probability of the driver filing an insurance claim in the future.3. Bank Loan Provisioning: Banks also use notching when setting provisions for loan losses. For instance, if a bank has a portfolio of loans and some of those loans are to borrowers with lower credit ratings, the bank may notch up its loan loss provisions to account for the increased risk of default on those lower-rated loans. This practice protects banks against potential losses and helps maintain their financial stability.

Notching refers to the practice of adjusting the credit rating of a specific debt issue within a company based on the characteristics of the issue, including seniority and security, among others.

Not necessarily. Notching can result in either a higher or lower credit rating depending on the specific characteristics of the debt issue.

Who performs the notching procedure?
