Learn how to interpret bond quotes, understand clean vs. dirty prices, and evaluate credit ratings. Gain insights into how rating changes affect bond prices and yields within the Canadian context.
Bond quotes and ratings are essential tools for evaluating fixed-income investments. The ability to accurately read these quotes and interpret credit ratings can markedly influence investment decisions, inform portfolio adjustments, and promote a deeper understanding of the Canadian bond market. In this section, we will explore how bond quotes are displayed, discuss the difference between clean and dirty prices, examine how credit ratings from major agencies work, and learn how changes in these ratings can impact bond yields and prices. We will also look at benchmark indices used as performance comparisons.
Bond quotes represent the current market price and other essential data you need when evaluating or trading a fixed-income security. These quotes typically appear on financial data platforms such as Bloomberg, Refinitiv Eikon, or online brokerage sites. While each platform has its design, most bond quote displays include the following core components:
Price
Coupon
Maturity Date
Yield
Special Features
When you see a bond priced on a financial platform (e.g., quoted as 99.50), that quote typically reflects the clean price. The clean price excludes any accrued interest the seller is owed since the last coupon payment. However, when you purchase a bond, you actually pay the dirty price, which is:
Dirty Price = Clean Price + Accrued Interest
Accrued interest is the interest that has accumulated between coupon payments. It compensates the seller for holding the bond over part of the coupon period.
To visualize the relationship:

A(Clean Price) --> B[+ Accrued Interest]
B --> C(Dirty Price)
Understanding the distinction between clean and dirty prices is crucial for both traders and long-term investors, especially in Canada where bond trades settle with a standard T+2 settlement cycle. From a tax perspective and a return perspective, you should carefully monitor accrued interest, as it influences your actual out-of-pocket expenses (and potential tax implications).
A bond’s credit rating reflects the issuer’s ability to meet its financial obligations. Ratings are typically assigned by recognized credit rating agencies, including DBRS Morningstar, Standard & Poor’s (S&P), and Moody’s Investor Services. In Canada, DBRS Morningstar is widely referenced, but many global investors also rely on S&P and Moody’s scales for comparative context.
Below is an approximate comparison:
Investment-grade ratings generally start from AAA (highest quality) to BBB- (i.e., BBB-, Baa3, or BBB low). Anything below these thresholds is considered high yield or “junk” status, implying a higher risk of default.
Credit rating agencies frequently review issuers and update ratings as new financial data emerges or sector-wide changes occur. When a bond’s credit rating is upgraded, its perceived default risk decreases, often leading to a price increase and a corresponding yield decrease.
Conversely, a downgrade signals heightened credit risk. Investors may sell the bond to reduce exposure, causing the bond’s price to fall and its yield to rise. It can also affect market liquidity, as some large institutional investors have mandates restricting the credit quality of their portfolio holdings—and they might be forced to sell downgraded bonds.
To measure how well a bond or bond portfolio is performing, investors often compare the yield or total return against a relevant benchmark index. In Canada, the most commonly referenced benchmark is the FTSE Canada Universe Bond Index, which covers a broad spectrum of Canadian investment-grade bonds. Other specialized indices track specific market segments, such as:
These indices serve as reference points:
• Portfolio Managers compare their portfolios’ returns and risk metrics to these benchmarks.
• Retail Investors can gauge whether their bond investments are in line with the broader market performance.
Imagine you access a financial terminal like Bloomberg or Refinitiv Eikon to review a recently issued Government of Canada bond quote. You see:
To figure out what you pay if you buy 10 bonds at a face value of $1,000:
• Clean price per $1,000 = $1,012.00
• Accrued interest per $1,000 = $3.00
• Dirty price per $1,000 = $1,012.00 + $3.00 = $1,015.00
• For 10 bonds (each with $1,000 face), total cost = 10 × $1,015 = $10,150
Since this is a Government of Canada bond, it likely has a top-tier credit rating (AAA from S&P, for instance). An upgrade in this context is unlikely, but if interest rates or the Canadian fiscal outlook changes, you might see an impact on its price.
Bond quotes provide crucial market data—price, yield, coupon, maturity date, and special features. However, understanding whether that price is clean or includes accrued interest is essential in determining the actual cost. Credit ratings serve as a compass for evaluating credit risk, guiding both institutional and retail investors in asset allocation. An upgrade usually supports higher bond prices and lower yields, whereas a downgrade triggers the opposite trend. Finally, benchmark indices such as the FTSE Canada Universe Bond Index help measure performance in comparison to the broader Canadian bond market.
This concludes Chapter 6, which introduces the foundational concepts of fixed-income securities, their key features, various types, and the practical knowledge required to understand how they are issued, traded, regulated, and analyzed in Canada. Mastery of this chapter is essential for anyone preparing for the Canadian Securities Course (CSC®) and for anyone working with bonds and related debt instruments under the oversight of the Canadian Investment Regulatory Organization (CIRO) and the broader framework set by the Canadian Securities Administrators (CSA).
• Clean Price – The bond price quoted in the market that does not factor in accrued interest.
• Dirty Price (Full Price) – The actual purchase price of a bond (Clean Price + Accrued Interest).
• Credit Rating – A grade assigned by a credit rating agency based on the issuer’s ability to meet its financial obligations.
• Benchmark Index – A standard index against which bond or portfolio performance is measured, such as the FTSE Canada Universe Bond Index.
