Quick Question (Class)

Among the bond types below, do you have a preference? What factors drive your choice—income needs, time horizon, taxes, credit risk, or interest-rate expectations?

Bring one clear recommendation and defend it.

Bond Outlook (2026) — Morningstar “Experts Forecast” (Bonds Only)

Warm-up (before you click): Based on today’s yield environment, what 10-year annual return would you expect for U.S. Aggregate Bonds and High Yield?

Write a number range + one sentence of mechanism. Then reveal the table and compare.

Core idea: Across forecasters, bond return expectations tend to cluster in the mid–single digits. A major driver is starting yield (plus spread/credit compensation), which anchors multi-year bond returns more tightly than equities.

Mini-discussion prompts
  1. Why do bond forecasts cluster more tightly than stock forecasts? Use “starting yield.”
  2. Why do high-yield forecasts exceed aggregate? What must be true about defaults/spreads?
  3. Why do “real return” and “nominal return” forecasts differ materially?

Bond Types: Characteristics, Suitability, and Risks

Refer to Chapter 6: Every bond yield can be thought of as Real rate + Expected inflation + Maturity premium + Liquidity premium + Default (credit) premium. The “Rate Components” column below indicates which components are typically most relevant for each bond type.
Bond Type Characteristics Suitability Main Risk Rate Components (Refer to Chapter 6)
Real + Infl + Maturity + Liquidity + Default
Short-Term Bonds Lower price volatility, typically lower yields Liquidity needs; conservative; near-term spending Reinvestment risk (rates may fall when you roll over) Real Infl Mat (low) Liq (low) Def (depends)
Short maturity → small maturity premium; returns mostly track short-rate policy + inflation.
Long-Term Bonds High sensitivity to rate changes; potentially higher yields Long horizon; higher risk tolerance; liability-matching Interest-rate risk (duration), inflation risk Real Infl Mat (high) Liq (varies) Def (depends)
Longer maturity → bigger maturity premium and higher duration sensitivity.
Corporate Bonds Higher yields; issuer fundamentals and ratings matter Income-seeking with risk capacity; spread pick-up Default + downgrade risk; liquidity risk; rate risk Real Infl Mat (varies) Liq (med–high) Def (high)
Extra yield is mainly default (credit) premium + often liquidity premium.
Treasuries Low credit risk; benchmark yield curve for pricing Stability; recession hedge; collateral/“risk-free” anchor Interest-rate risk (especially long end); inflation risk Real Infl Mat (varies) Liq (low) Def (≈0)
Minimal default and liquidity premia; yield mostly = real + inflation + maturity.
Municipals Tax advantages; credit varies by issuer; call features common Higher tax bracket; tax-efficient income; state-specific strategies Credit + liquidity risk; call risk; rate risk Real Infl Mat (varies) Liq (med) Def (varies)
Compare after-tax yield. Credit and liquidity premia vary widely across issuers.
Prompt: Which bond type fits a short horizon vs long horizon? Which fits a high-tax investor? Which fits recession-hedging?
Click to reveal: Suggested answers (hidden key)

1) Short horizon vs long horizon

  • Short horizon: Short-term bonds or short/intermediate Treasuries (lower duration; match near-term cash needs).
  • Long horizon: Longer-term bonds (often long Treasuries for safety) if liability-matching / locking yields is the goal—accept higher duration risk.

2) High-tax investor

  • Municipal bonds (especially in higher tax brackets), because interest may be exempt from federal taxes (and sometimes state taxes).
  • Compare with tax-equivalent yield before choosing.

3) Recession-hedging goal

  • Treasuries (often intermediate-to-long) are the classic hedge: minimal credit risk and potential price gains if rates fall.
  • High yield is typically not a hedge in recessions (spreads widen, defaults rise).

Relationship Between Bond Prices and Interest Rates

Key rules

  • When market rates rise, fixed-rate bond prices fall.
  • Lower coupon bonds have more interest-rate risk than higher coupon bonds.
  • Longer maturities have more interest-rate risk than shorter maturities.

SEC reading: Interest Rate Risk

Core approximation

If yields change a little:

ΔP/P ≈ −(Modified Duration) × Δy

Example: Modified Duration = 7.8 ⇒ if yields rise by 1.00%, price falls by about 7.8%.

Duration: Meaning + Mini-Check (Interactive)

Meaning

  • Duration measures a bond’s interest-rate sensitivity.
  • High duration = price moves a lot when yields move (more volatile).
  • Low duration = price moves less when yields move (more stable).
Rule of thumb: longer maturity + lower coupon → higher duration.

Dropping-rate environment

  • If rates are expected to drop, high-duration bonds tend to gain more (bigger price increase).
  • Tradeoff: if yields later rise, high duration means larger price losses.
  • After rates drop, new reinvestment yields are lower (reinvestment risk increases).

Quick idea

Approximation: ΔP/P ≈ −(ModDur) × Δy

Use the mini-check below to sanity-check your intuition.

Duration Mini-Check

Enter a Modified Duration and a yield change (Δy). The tool computes the approximate price impact. Use +1 for +1.00% and -1 for -1.00%.

Higher = more rate sensitivity.
+ means yields rise; − means yields fall.
Use 1000 for a par bond example.
Approx % price change
Uses: −ModDur × (Δy/100).
Approx $ change (using your price)
Approx $ impact = Price × (% change).
Interpretation
Rates up → price down; rates down → price up.
Click to reveal: Instructor note (how to talk through this)
  • Students should say: “High duration is a lever. If you expect yields to fall, you want more duration; if you fear yields rising, you want less.”
  • Remind: This is a first-order approximation; convexity matters for bigger moves and for callable bonds.

Bond Pricing and Duration in Excel

Price (annual coupon)

Price = ABS( PV( ytm, years, coupon*1000, 1000 ) )

Example: =ABS(PV(8.2%, 8, 65, 1000))

Yield to Maturity (annual)

YTM = RATE( years, coupon*1000, -price, 1000 )

Example: =RATE(15, 85, -1120, 1000)

Semiannual coupon

Price = ABS( PV( ytm/2, years*2, coupon*1000/2, 1000 ) )

YTM = RATE( years*2, coupon*1000/2, -price, 1000 ) * 2

Click to reveal: Duration functions (Excel) + interpretation

Macaulay Duration

=DURATION(settlement, maturity, coupon, yld, frequency, basis)

Example: =DURATION(DATE(2026,1,27),DATE(2036,1,27),0.05,0.045,2,0)

Interprets as a cash-flow “center of gravity” (years).

Modified Duration (use for sensitivity)

=MDURATION(settlement, maturity, coupon, yld, frequency, basis)

Example: =MDURATION(DATE(2026,1,27),DATE(2036,1,27),0.05,0.045,2,0)

If ModDur = 8, then +1% yield move ≈ −8% price move.

Convexity (optional extension)

=CONVEXITY(settlement, maturity, coupon, yld, frequency, basis)

Convexity improves accuracy for larger yield moves (and highlights why callable bonds behave differently).
Basis is the day-count convention (0 = US 30/360 is common in textbook problems).
Tip: be consistent with sign conventions in Excel (price is negative inside RATE()).

Practice #1 “Next Step”: Solve YTM in Excel (Annual & Semiannual)

Annual coupon (freq = 1)

YTM (annual):
=RATE(Years, Coupon, -Price, FaceValue)
Example: =RATE(8,65,-903.04,1000)
Sanity check: if Price < 1000, then YTM > coupon rate.

Semiannual coupon (freq = 2)

Periodic yield (per 6 months):
=RATE(Years*2, Coupon/2, -Price, FaceValue)
Nominal annual YTM (APR):
=RATE(Years*2, Coupon/2, -Price, FaceValue) * 2
Example: =RATE(16,32.5,-903.04,1000)*2

Optional: Effective annual rate (EAR)

If your periodic rate is r/2:
EAR = (1 + r/2)^2 − 1
Most textbook “YTM” quotes are nominal APR for semiannual coupons.

Cash-Flow Timeline (Practice #1 — Given YTM, find Price)

Change the inputs and click Update to see how cash flows move on the timeline. (Price today is a negative cash flow at t=0.)
If semiannual: coupon per period = coupon/2.
Price (t=0) Coupons / FV
Standard: show inputs clearly (Rate, Nper, Pmt, PV, FV).

Where to Invest in 2026 (Key Takeaways) — “Duration matters” (JPMorgan / Priya Misra)

Core themes (talking points)

  • Cash yields can reset downward quickly.
  • If rates fall, longer-duration bonds may benefit from price gains.
  • Credit spreads can be tight; risk is not always well-compensated.
  • EM yields can be higher but add FX + political risk.
Quick definitions (for students)
  • Duration: sensitivity of price to yield changes.
  • Rule of thumb: ΔP/P ≈ −(ModDur) × Δy.
  • Tradeoff: higher duration helps more if rates fall, hurts more if rates rise.

Discussion prompt

If the market expects rate cuts, do you move to longer-term bonds now? What tradeoffs matter most: duration, reinvestment risk, or credit risk?

Write: (1) your choice (short/intermediate/long), (2) one sentence on “why duration,” (3) one risk you’re accepting.
Suggested structure (hidden key)
  1. View: “I expect yields to (fall / stay / rise) over the next (X) months.”
  2. Duration choice: “Therefore I want (more / less) duration.”
  3. Risk tradeoff: “The key risk is (price volatility / reinvestment / credit spread widening).”

2) Critical Thinking Challenge (choose ONE)

Option A — 10Y vs 2Y spread interpretation (Yield Curve Signal)
Using the current 10Y–2Y spread, what do you conclude about the coming year? Would you recommend short-duration, intermediate, or long-duration bonds today? Defend using recession risk, rate expectations, and Fed policy.
Data: FRED T10Y2Y
  • Include the latest value (and the date) you used from FRED.
  • State your duration choice clearly (short / intermediate / long) and why.
  • One risk you are watching (inflation surprise, growth shock, credit spreads, etc.).
Option B — Duration Stress Test (numbers required)
Pick one bond type you would hold today (Treasury, investment-grade corporate, high yield, or municipal). Use a modified duration (from Excel MDURATION, a fund fact sheet, or another credible source) and estimate the price impact if yields move:
Shock Compute
+1.00% yield change ΔP/P ≈ −(ModDur) × (0.01)
−1.00% yield change ΔP/P ≈ −(ModDur) × (−0.01)
  • Show your ModDur value and where it came from.
  • Report both % price changes (two numbers).
  • Explain (5–7 sentences) why that duration risk fits your horizon and risk tolerance.
  • Note one caveat: convexity, callable bonds, spread changes, or reinvestment risk.
Standard: concise, structured response with at least one data reference (FRED, fund fact sheet, or Excel output) and a clear recommendation.
