CFA Level 1 November 2026: Most Important Fixed Income Questions

CFA Level 1 November 2026 Most Important Fixed Income Questions: Fixed income securities form a critical component of global financial markets. Understanding how bond prices react to interest rate shifts, credit rating adjustments, and structural provisions is essential for investment analysis. This guide reviews key valuation mechanics, duration metrics, credit risk frameworks, and debt structures tested in the CFA Level 1 exam.

Bond Retirement And Sinking Fund Provisions

A sinking fund provision is a contractual requirement in a bond indenture that obligates the issuer to retire a predetermined portion of the bond issue's outstanding principal balance each year prior to maturity.

• Mechanism: The issuer can retire bonds by either purchasing them in the open market or calling a specified fraction of the issue randomly at the sinking fund price, typically par.

• Credit Implications: This provision reduces default risk for investors by amortizing the principal balance over the life of the bond rather than facing a large lump-sum payment at maturity.

Yield Curve Shifts And Duration Measures

Duration measures the sensitivity of a bond's price to interest rate changes. Different types of duration apply depending on the bond's structure and the type of yield curve shift.

Duration Metrics Comparison

Traditional duration measures assume a parallel shift in the yield curve. When shifts are non-parallel, standard duration fails to accurately estimate price changes. Under these conditions, Key Rate Duration must be used to capture changes in the shape and slope of the benchmark yield curve.

Bond Price Sensitivity: Duration And Convexity

To estimate the total percentage change in bond price resulting from a change in yield, both first-order duration and second-order convexity effects are combined:

Percentage Change in Price = [ -Annual Modified Duration * Change in YTM ] + [ 0.5 * Annual Convexity * (Change in YTM)^2 ]

(Memory Tip: When calculating numerical duration and convexity approximations, enter changes in yield in decimal format, such as 10 bps = 0.0010, to prevent scaling errors in squared terms.)

Positive vs. Negative Convexity

• Positive Convexity (Option-Free Bonds): When yields decrease, bond prices increase at an increasing rate. When yields increase, bond prices decrease at a decreasing rate. Price gains from a yield decline exceed price losses from an equal yield increase.

• Negative Convexity (Callable Bonds and Mortgage-Backed Securities): When yields drop significantly, the issuer's incentive to call the bond or prepay mortgages rises. Price upside is capped at the call price, causing the price-yield curve to flatten.

Embedded Options And Valuation Dynamics

Embedded options change the risk and return profile of standard debt securities:

• Callable Bonds: Contain an embedded call option owned by the issuer. Investors demand a higher yield to compensate for call risk and reinvestment risk.

• Putable Bonds: Contain an embedded put option owned by the bondholder. Investors accept a lower yield for downside protection.

• Convertible Bonds: Allow investors to convert debt into a specified number of common shares based on the conversion ratio.

Spot Rates, Forward Rates, And Pricing Equivalence

A bond's no-arbitrage price calculated by discounting each cash flow at its maturity-matched spot rate equals the price obtained by discounting all cash flows at a single uniform Yield to Maturity (YTM).

• Implied Forward Rate: The theoretical break-even reinvestment rate calculated from the spot curve that equates the total return of a multi-period investment with a sequence of shorter-term investments.

• (Memory Tip: Use the additive linear approximation shortcut to avoid full geometric compounding when solving quickly: Forward Rate ≈ (T2  S_T2) - (T1 * S_T1).* )

Matrix Pricing

Matrix pricing estimates the required Yield to Maturity (YTM) of an illiquid bond by interpolating between active yields of comparable maturities:

YTM = YTM_low + [ (Target Maturity - Maturity_low) / (Maturity_high - Maturity_low) ] * (YTM_high - YTM_low)

Corporate Issuers is one of the areas covered in the broader CFA programme, which focuses on investment knowledge, financial analysis and professional decision-making.

Credit Risk Assessment And Ratings Architecture

Credit risk analysis evaluates the likelihood of a borrower failing to meet scheduled debt obligations.

Credit Loss Formulation

• Expected Loss = Probability of Default (PD) * Loss Given Default (LGD)

• Loss Given Default (LGD) = 1 - Recovery Rate (RR)

• As the Recovery Rate increases, LGD decreases, directly reducing Expected Loss.

Credit Rating Scale And Notching

• Lowest Investment Grade Rating: BBB- (S&P / Fitch) or Baa3 (Moody’s). Instruments rated below this level transition into speculative grade (high-yield debt).

• Credit Rating Notching: Adjustments made to specific debt obligations relative to an issuer's baseline rating. The adjustment depends on the rating of the issuer's senior unsecured debt. Notching is narrower for higher-rated credits and widens for lower-rated credits.

• Structural Subordination: Arises when a parent holding company relies on dividends from operating subsidiaries to service debt. Operating subsidiary debt is serviced first, subordinating the parent company debt.

• Pari Passu Principle: Ensures that all creditors within the same seniority class share on equal footing during liquidation distributions, regardless of maturity differences.

Mortgage Prepayment Risks And Securitization

Mortgage-backed securities (MBS) carry unique cash flow uncertainties based on interest rate cycles.

• Non-Recourse Loans: The lender's claim is strictly limited to seizing the underlying collateral property. Borrowers' personal assets cannot be touched, increasing the risk of strategic default if property values decline below loan balances.

Key Analytical Formulas And Quotation Conventions

• Price Value of a Basis Point (PVBP): Measures the absolute price change for a 1 basis point (0.01%) yield change:
  PVBP = Initial Price * Modified Duration * 0.0001

• Effective Duration:
  Effective Duration = (V_minus - V_plus) / (2 * V_0 * Delta Yield)

• Quoted vs. Settlement Price: Bonds are quoted using the Flat Price (Clean Price). Trades settle at the Full Price (Dirty Price):
  Full Price = Flat Price + Accrued Interest

• Accrued Interest: Depends only on the coupon rate and days elapsed. It does not depend on the market discount rate (YTM).

• Eurobonds: Issued outside the jurisdiction of any single country and denominated in a currency other than that of the country where traded.
