Key Outcomes Summary & Practice Problems
What you must be able to do
Curriculum Year: 2026
Describe fixed‑income market segments and their issuer and investor participants — categorized by issuer type (sector), credit quality, and time to maturity.
Describe types of fixed‑income indexes — broad‑based aggregate indexes vs. narrower indexes (by sector, credit quality, maturity, geography, ESG).
Compare primary and secondary fixed‑income markets to equity markets — primary issuance (public offerings, private placements, shelf registrations) and secondary trading (OTC, liquidity, bid‑offer spreads).
1 · Fixed‑Income Market Segments
Three Dimensions of Classification
Issuer type (sector): Sovereign, non‑sovereign government, corporate, securitized (ABS/MBS).
Credit quality: Investment grade (IG) vs. high yield (HY) / speculative grade. Measured by credit ratings (S&P, Moody's, Fitch).
Time to maturity: Money market (≤ 1 year) vs. capital market (> 1 year).
Credit Ratings — S&P Scale
Investment grade: BBB‑ (S&P/Fitch) or Baa3 (Moody's) and above. Low default risk.
High yield / speculative grade: BB+ (S&P/Fitch) or Ba1 (Moody's) and below. Higher default risk, higher expected returns.
Fallen angels: Formerly investment‑grade issuers whose credit quality has deteriorated.
Issuers Across the Spectrum
Developed market sovereign: Lowest credit risk (often AAA/AA). Default‑risk‑free benchmark.
Investment‑grade corporate: Strong cash flows; unsecured debt; few restrictive covenants.
High‑yield corporate: Higher default risk; secured debt; more restrictive covenants; shorter maturities.
Investors Across the Spectrum
Money market funds: Short‑term, high credit quality (commercial paper, T‑bills).
Core bond funds: Investment‑grade, intermediate to long term.
Pension funds / insurers: Long‑term liabilities; match duration with long‑term bonds.
High‑yield funds / hedge funds: Seek higher returns; accept greater credit risk.
2 · Fixed‑Income Indexes
Key Differences from Equity Indexes
More constituents: A single issuer may have many bonds outstanding; some indexes have > 10,000 constituents.
Higher turnover: Bonds mature and new bonds are issued; indexes rebalance monthly.
Market‑value weighting: Weighted by market value of debt outstanding; government debt often dominates broad indexes.
Bond funds typically hold a representative sample rather than all constituents.
Three Dimensions of Classification
Fixed‑rate, investment‑grade capital market securities from 28 developed and emerging markets. Includes sovereign, government, corporate, and securitized issuers. Excludes high‑yield and unrated debt.
US dollar‑denominated sovereign debt of emerging market issuers with ratings at or below investment grade. Minimum USD500M outstanding, ≥ 2.5 years to maturity.
Euro‑denominated corporate bonds with MSCI ESG rating ≥ BBB. Excludes issuers involved in alcohol, tobacco, gambling, thermal coal, and other controversial activities.
Tracks investment‑grade bonds issued in Japan. Used to evaluate managers focused on a single market.
Index uses: Market performance evaluation, investment manager benchmarking, and indexed investment strategies (ETFs, mutual funds).
Rebalancing: Monthly; bonds that fall below minimum maturity or credit rating are removed; new issues added.
Hedged vs. unhedged returns: Index returns may include currency gains/losses (unhedged) or offset using currency forwards (hedged).
3 · Primary and Secondary Fixed‑Income Markets
Primary Markets
Public offering: Any member of the public may buy the bonds. Underwritten by investment banks.
Private placement: Bonds sold to a select group of investors (or a single investor). Non‑underwritten, unregistered.
Debut issuer: First‑time bond issuer; often replaces bank loans with bonds; involves roadshows and investor education.
Shelf registration: Frequent issuers use a broad offering circular updated regularly; allows opportunistic issuance.
Reopening: Increasing the size of an existing bond issue with a price significantly different from par.
Sovereign issuance: Usually via public auction led by the national Treasury/Finance Ministry.
Investment‑Grade Corporate Bond Issuance Timeline
Secondary Markets
Quote‑driven / OTC: Most bonds trade over‑the‑counter (not on exchanges), mediated by broker/dealers.
Bid‑offer spread: Key liquidity measure. On‑the‑run sovereign bonds trade at fractions of a basis point; illiquid corporate bonds may trade at 10–20 bps or more.
On‑the‑run vs. off‑the‑run: Most recently issued sovereign bonds are most liquid.
Distressed debt: Bonds of issuers near or in bankruptcy; trade well below par; often bought by hedge funds seeking equity‑like returns.
Equity vs. debt delisting: Equity may be delisted from exchanges if it fails listing requirements; distressed debt trades until the issuer liquidates or restructures.
Illiquid bonds: Many bonds do not trade regularly; prices are estimated using matrix pricing (comparable bonds).
Feature | Fixed‑Income Markets | Equity Markets |
|---|---|---|
Primary issuance | Public offerings, private placements, shelf registrations, auctions | IPOs, follow‑on offerings, private placements |
Secondary trading | Primarily OTC (quote‑driven) | Primarily exchange‑based (order‑driven) |
Liquidity | Varies widely; on‑the‑run sovereign very liquid; many bonds illiquid | Generally more liquid; most stocks trade daily |
Issuer concentration | One issuer may have many bonds outstanding | One issuer typically has one common equity class |
Turnover | Higher (maturities, new issues) | Lower (no maturity) |
