Understanding Bond Ratings
August 11, 2025Understand Credit Guarantee
As Cambodia’s bond market continues to develop, credit ratings are playing an increasingly important role for issuers, investors, regulators, and guarantors. They serve as a standardized measure of credit risk, bringing greater transparency and confidence to the market while enabling consistent comparisons across different borrowers. Such ratings help guide bond pricing, assess creditworthiness, and support compliance with regulatory or investment policy requirements. A deeper understanding of rating methodologies enables market participants to make better-informed decisions, foster investor confidence, and enhance the credibility and efficiency of Cambodia’s capital market.
What Are Bond Ratings?
A bond rating is an independent opinion issued by credit rating agencies on a bond issuer’s creditworthiness. It evaluates the bond issuer’s financial strengths and the capacity to repay the bond principal and interest according to contract. These ratings are published by international credit rating agencies such as Standard & Poor’s (S&P), Moody’s, and Fitch Ratings, as well as local institution like the Rating Agency of Cambodia (RAC).
While each agency applies its own rating scale, all systems broadly categorize bonds based on credit quality and risk level, typically classifying them as “investment grade,” “non-investment grade”, or “unrated”. Investment-grade bonds are generally viewed as having low risks of default and stable but tend to offer lower returns. In contrast, non-investment grade bonds, also known as speculative, high-yield, or junk bonds—carry higher credit risk but offer investors the potential for higher returns. For example, investment-grade bonds, as shown in the table below, are rated Baa3/BBB– or higher. The highest rating is Aaa/AAA, indicating the strongest credit quality, while the lowest is D, representing default. Modifiers such as plus or minus signs are used to provide finer distinctions within each rating category.
Credit rating symbols are consistent across industries. For example, a BBB rating assigned to a borrower in the service sector carries the same probability of default (PD) as a BBB rating in the manufacturing sector. However, these ratings reflect the overall creditworthiness of the borrower and do not capture the specific risk of individual debt facilities. In contrast, facility ratings assess the credit risk of specific loans or debt instruments by considering factors such as collateral type, seniority, and recovery prospects. For instance, a loan secured by real estate or fixed deposits may receive a higher facility rating than an unsecured loan from the same BBB-rated issuer, due to the lower expected loss in the event of default.
How Are Bonds Rated?
Credit rating agencies apply a combination of quantitative and qualitative analysis to assess a bond issuer’s credit risk. Quantitative factors include financial performance indicators such as cash flow, leverage, liquidity, and capital structure. Qualitative factors cover industry risk, country risk, business position, management and governance quality, and regulatory environment. After evaluating the issuer’s overall creditworthiness, the rating agency reviews the specific bond’s features—such as seniority, collateral, and credit enhancements. The rating reflects the relative likelihood of default and is assigned through a committee process. It is also monitored regularly for potential changes.
Bond ratings are forward-looking and typically reflect the rating agency’s opinion of credit risk over a horizon of 6 months to 2 years, depending on the credit quality and volatility of the issuer. This outlook considers the potential impact of foreseeable events on the bond’s ability to meet its financial obligations, but it is not a guarantee of future performance. While credit ratings are a valuable tool for assessing bond risk, investors are encouraged not to rely solely on ratings when making investment decisions. Therefore, investors should use credit ratings alongside their own due diligences such as reviewing financials, understanding bond terms, and analyzing market conditions to make a well-informed decision.
Implications for Bond Market in Cambodia
Both local and international credit ratings play an essential role in improving transparency, pricing accuracy, and investor confidence in Cambodia’s growing bond market. They provide a standardized assessment of credit risk, support regulatory oversight, and help attract long-term institutional investors.
As the national credit guarantee institution, the Credit Guarantee Corporation of Cambodia (CGCC) plays a strategic role in supporting the development of the bond market, particularly through its guarantees on Khmer Riel-denominated bonds listed on the Cambodia Securities Exchange (CSX). By enhancing the credit profile of local issuers, CGCC’s bond guarantees help reduce perceived default risk, improve access to capital, and expand investor participation—thereby contributing to the deepening and credibility of Cambodia’s capital market.
