Yield to Maturity Explained: YTM, YTW & Q1 2026 Investment Grade Bond Yields

21st April 2026 | by the Investment Grade Team

in ,

Yield to maturity (YTM) is the total annualized return an investor earns on a bond if they hold it to maturity and every coupon payment gets reinvested at the same yield. For investment grade corporate bonds in Q1 2026, YTM ranges from roughly 4.6% for AAA paper to 5.4% for lower-tier BBB credits, with the broad ICE BofA US Corporate Index sitting at 5.22% as of late March 2026. YTM is the single most important number to understand before buying any bond because it combines the coupon rate, the current market price, and the time to maturity into one comparable figure. Coupon rate tells you what the bond pays annually as a percentage of par; YTM tells you what you will actually earn at today’s market price. These numbers diverge whenever a bond trades at a discount or premium to par, which in a post-2022 rate environment means nearly every bond issued before 2023.

What Is Yield to Maturity?

Yield to maturity answers the question every bond buyer needs answered: if I buy this bond today at the current market price, hold it until the stated maturity date, and reinvest every coupon payment at the same yield, what annualized return will I earn on the total investment? YTM is expressed as a percentage and functions as the internal rate of return (IRR) on the bond’s cash flows. It is the standard yield convention used across institutional bond markets, dealer quote sheets, Bloomberg terminals, and every major brokerage platform.

YTM matters because the coupon rate alone tells you almost nothing about what a bond will actually return. A bond with a 2.00% coupon sounds unattractive, but if it trades at 82 cents on the dollar with five years to maturity, its YTM is closer to 6.1%. A bond with a 6.00% coupon sounds great, but if it trades at 108 cents with three years to maturity, its YTM is closer to 3.2%. The market re-prices bonds continuously to deliver a YTM that reflects current interest rates and credit conditions. Understanding YTM is what lets an investor compare a 2020-vintage Apple bond trading at 85 cents to a 2025-vintage AbbVie bond trading at 102 cents on equal terms.

The YTM Formula and What Drives It

The YTM formula solves for the discount rate that makes the present value of all future coupon payments plus the final par value equal to the current market price of the bond. The simplified equation is:

Price = C × [1 − (1 + YTM)^−n] / YTM + FV / (1 + YTM)^n

Where C = annual coupon payment, n = years to maturity, FV = face value at maturity, and YTM = yield to maturity as a decimal.

This equation cannot be solved algebraically for YTM. It must be solved iteratively using a financial calculator, a spreadsheet function (RATE or YIELD in Excel, IRR on cash flows), or by approximation. Every bond trading platform and Bloomberg terminal runs this calculation automatically, which is why investors can simply read the YTM off the screen rather than calculate it by hand.

Four inputs drive YTM in any market environment: the bond’s coupon rate (fixed at issuance), the current market price (moves daily), the time remaining to maturity (shortens daily), and the face value at maturity (usually $1,000 per bond). When market interest rates rise, bond prices fall, which pushes YTM higher to compensate. When credit spreads widen because of deteriorating fundamentals, prices fall for that issuer specifically, and YTM rises. The inverse relationship between bond price and yield is the single most important mechanic in fixed income.

YTM vs. Coupon Rate vs. Current Yield vs. YTW

Four related yield measures appear on every bond quote, and each answers a different question. The table below summarizes what each one captures.

Yield MeasureWhat It MeasuresWhen to Use It
Coupon RateAnnual interest as a percentage of face value, fixed at issuanceUnderstanding the bond’s stated contractual payment
Current YieldAnnual coupon divided by current market priceRough estimate of income yield, ignores capital gain or loss
Yield to Maturity (YTM)Total annualized return if held to maturity, assumes coupon reinvestment at YTMComparing bonds with different coupons, prices, and maturities
Yield to Worst (YTW)Lowest possible yield across all call dates and maturity, assuming worst-case for investorCallable bonds where issuer can redeem early at par
Yield to Call (YTC)Return if the bond is called on the earliest call dateCallable bonds trading above par where a call is likely

For most investment grade corporate bonds, YTM and YTW are the two numbers that matter. YTM is the headline figure on non-callable bullet bonds. YTW is the relevant figure for callable structures because it assumes the issuer will exercise the call option that produces the lowest return for the investor. Most dealer quote sheets show both. When the YTW is materially below the YTM, the bond is callable and trading above par, meaning the market expects the call will likely be exercised.

Investment Grade YTM by Rating Tier (Q1 2026)

Q1 2026 investment grade corporate bond yields sit near the high end of their 15-year range. The ICE BofA US Corporate Index closed at 5.22% effective yield on March 26, 2026, with individual rating tiers spanning roughly 4.6% at the AAA end to 5.4% at the lower BBB end. The table below shows current approximate YTM levels across the investment grade spectrum alongside 10-year Treasury comparison.

Approximate YTM levels as of April 2026. ICE BofA US Corporate Index: 5.22% (March 26, 2026). 10-year Treasury: 4.25% (April 20, 2026). Not investment advice. Source: FRED, ICE BofA, U.S. Treasury.

Context matters for reading these numbers. The Bloomberg US Corporate Bond Index average YTW of 4.8% at the end of November 2025 sits well above its 15-year average of roughly 3.2% from 2010 through 2021, while the peak was 6.4% in late 2023. Today’s yields are elevated relative to the post-2008 era but still below the 2022 to 2023 peak. For a deeper analysis of where spreads sit relative to history, see Credit Spreads Explained.

Worked YTM Example: A 5-Year Johnson & Johnson Bond

Assume a Johnson & Johnson senior unsecured bond with the following characteristics:

Coupon Rate: 2.625%
Face Value: $1,000
Maturity: 5 years remaining
Current Market Price: $895 (89.5 cents on the dollar)
Annual Coupon Payment: $26.25
Rating: AAA / Aaa

The bond trades at a discount to par because it was issued during the 2020-2021 low rate period with a below-market coupon. An investor buying at $895 today receives $26.25 per year in coupon income and $1,000 at maturity in five years, which means the $105 capital gain between purchase price and par adds meaningfully to the total return.

Solving iteratively for the discount rate that equates the present value of five annual $26.25 coupons plus the $1,000 terminal payment to $895 produces a YTM of approximately 4.97%. That 4.97% YTM is dramatically higher than the 2.625% coupon rate and reflects what a new buyer at today’s price would actually earn. The original buyer who paid $1,000 at issuance is still earning only 2.625% on their capital; the YTM that matters for them is the one they locked in at purchase, not today’s market YTM.

This is the single most common source of confusion among bond investors. Coupon rate is locked in at issuance for the original buyer. YTM is what the market re-prices daily for every new buyer. When rates rise after issuance, bond prices fall, and new-buyer YTMs rise above the coupon rate. When rates fall after issuance, the opposite happens.

The Price and Yield Relationship

Bond prices and YTM move inversely. When YTM rises, price falls. When YTM falls, price rises. The magnitude of the move depends on the bond’s duration, a measure of interest rate sensitivity. A long-duration bond (20 to 30 years) will move roughly twice as much per 1% change in yield as an intermediate bond (7 to 10 years). A short-duration bond (1 to 3 years) will move only modestly even on large yield shifts.

Bond Trading StatusCoupon vs. Market YTMInvestor Return Profile
At Par ($1,000)Coupon = Market YTMAll return comes from coupon income
Discount (<$1,000)Coupon < Market YTMReturn = coupon income + capital gain at maturity (pull to par)
Premium (>$1,000)Coupon > Market YTMReturn = coupon income − capital loss at maturity

Most investment grade corporate bonds issued during the 2020 to 2021 low-rate era now trade at significant discounts. A 10-year bond issued with a 2.00% coupon in 2021 trades around 75 to 80 cents on the dollar today, with YTM near 5.0%. That pull-to-par dynamic is part of why institutional buyers favor discount paper: a portion of the return is booked as capital gain rather than interest income, which can have tax advantages in certain accounts. For the mechanics of how rating tiers map to these yields, see Bond Ratings Explained.

Yield to Worst (YTW) for Callable Bonds

Many investment grade corporate bonds are callable, meaning the issuer has the right (but not the obligation) to redeem the bond at par before maturity. This right is valuable to the issuer because it lets them refinance at lower rates if yields fall after issuance. For the investor, a call is generally bad news: it caps upside and forces reinvestment at whatever lower yield prevails at the time of the call.

YTW calculates the lowest possible yield across every possible call date and the final maturity. It assumes the issuer will always exercise whichever option produces the worst outcome for the investor. When a callable bond trades above par, the call becomes the binding constraint on upside because the issuer can redeem at $1,000 no matter how high the market price rises. In that environment, YTW is the number to focus on, not YTM.

Quick rule: For non-callable bullet bonds, YTM and YTW are identical. For callable bonds, YTW is always less than or equal to YTM. When YTW is materially lower than YTM, the market is telling you the call is likely to be exercised. Serious bond buyers focus on YTW for callable paper.

How YTM Compares to NNN Real Estate Cap Rates

Investment grade corporate bonds and NNN real estate leased to the same tenant are economically similar instruments backed by identical credit. Both require the tenant to make contractual payments to the investor. The difference is that bonds pay through coupon yield and NNN properties pay through cap rate (annual rent divided by purchase price). The structural spread between the two tells you how much extra yield real estate offers for the same credit.

Tenant / IssuerRatingBond YTMNNN Cap RateSpread
McDonald’sBBB+~4.9%4.25% to 4.75%−65 to −15 bps
Dollar GeneralBBB~5.3%6.75% to 7.75%+145 to +245 bps
CVS HealthBBB~5.4%6.50% to 7.50%+110 to +210 bps
AutoZoneBBB~5.2%5.75% to 6.75%+55 to +155 bps
7-ElevenA~5.0%5.00% to 6.00%+0 to +100 bps

Approximate Q1 2026 figures. Bond YTM based on approximate 10-year senior unsecured pricing. NNN cap rates based on market ranges for lease terms above 10 years. Not investment advice.

For lower-tier investment grade tenants like Dollar General and CVS, the NNN cap rate exceeds the bond YTM by 110 to 245 basis points on identical credit. That spread is real, and it exists because real estate is illiquid, property-specific, and carries lease structure risk. For investors willing to accept those trade-offs, the NNN wrapper also delivers tax advantages unavailable to bondholders: depreciation, 1031 exchange eligibility, and long-term capital gains treatment at disposition. The Investment Grade Credit Tenant Ratings database tracks the current credit profile of 195+ NNN tenants, which drives both the bond YTM and the cap rate for each.

What Moves YTM

Three forces push YTM up or down over time. Understanding which one is active matters for any bond investor deciding whether to buy, hold, or sell.

Treasury Yield Changes. The risk-free 10-year Treasury yield is the floor for investment grade corporate bond yields. When the Treasury yield rises, IG corporate YTM rises by roughly the same amount, holding credit spreads constant. The Treasury yield itself reflects inflation expectations, Federal Reserve policy, and term premium. In 2022, Treasuries rose over 250 basis points, and IG corporate YTMs rose commensurately.

Credit Spread Changes. Credit spread is the extra yield corporate bonds offer over comparable-maturity Treasuries to compensate for default risk. When spreads tighten (as they have since 2023), corporate YTM falls relative to Treasuries. When spreads widen during recessions or credit stress, corporate YTM rises independent of Treasury moves. The April 2026 IG spread near 77 bps is near the tightest level in over two decades.

Issuer-Specific Credit Events. A rating downgrade, earnings disappointment, or sector stress can push one issuer’s YTM meaningfully higher without moving the broad index. The Walgreens downgrade to BB+ in 2024 pushed Walgreens bond YTMs from roughly 5.25% to 7.50%+ over a few weeks, with the bulk of the move occurring in the days surrounding the rating action. Monitoring issuer credit trajectory is part of active IG portfolio management.
