Building a Fixed-Income Portfolio

Lakshmi Rao is 64, a retired schoolteacher in Hyderabad, widowed, living off a corpus of ₹95,00,000 — ninety-five lakh, or a little under a crore. She needs about ₹50,000 a month to live on. She has done everything carefully: a pension, some fixed deposits, the Senior Citizens' Savings Scheme. And yet two sentences make her stomach tighten. The first: “you should build a proper fixed-income portfolio” — which sounds like something with a Bloomberg terminal and a suit. The second, quieter and worse: “what happens to my income when my big FD matures and interest rates have fallen?”

Both fears melt on contact with the truth. You are not going to build anything exotic here. You already own the pieces — an FD, a scheme, maybe a debt fund a bank once signed you into. A fixed-income portfolio is just those pieces, arranged on purpose instead of by accident. And the second fear — the income cliff — turns out to have a plain, almost mechanical defence that a schoolteacher can set up in an afternoon. This lesson is the arranging.

This lesson assembles; it does not re-teach each instrument. You met them already: what a bond is and the price–yield seesaw (Lesson 32 · Bonds From Scratch), government securities (Lesson 33 · Government Securities), buying them yourself on RBI Retail Direct (Lesson 34 · Buying Government Bonds Yourself), the tax-smart and floating-rate bonds (Lesson 35 · The Tax-Smart Bonds), and corporate bonds, FDs and debt funds with their post-2023 tax (Lesson 36 · Corporate Bonds, FDs & Debt Funds). Here we pull them into one whole.

Before we arrange anything, it helps to know what the arrangement is for. People think “safe money = the money that pays interest.” That is one job. A well-built sleeve does three, and the other two are the ones beginners forget.

1. Income. Coupons and interest arrive on a schedule — the ₹5,57,500 a year Lakshmi will live on, or, for a younger saver, cash that can be redeployed without selling a growth asset. This is the obvious job.
2. Stability — the ballast. When equities fall 30–40% in a crash, the bond sleeve barely moves. It steadies the whole portfolio's value, and it steadies you, so you don't panic-sell shares at the bottom. A boat with ballast rolls less.
3. Dry powder. This is the subtle one, and worth a new phrase.

Hold those three jobs in mind — income, ballast, dry powder — because they explain every choice that follows. The reason Lakshmi keeps a liquid buffer that “earns almost nothing” is that its job isn't yield; it's dry powder and next month's groceries. Judge each piece by the job you gave it, not by its interest rate alone.

Lakshmi's sharper fear deserves its proper name. Suppose she does the tidy thing and puts ₹30,00,000 — thirty lakh — into a single five-year FD at 7%. For five years it pays ₹2,10,000 a year (₹30,00,000 × 7%), which means ₹17,500 a month of dependable income. Lovely. Then, at the end of year five, the FD matures and hands her back ₹30,00,000 — and she has to put it somewhere again. If rates have drifted down to 5% by then, her only option is to reinvest the whole sum at 5%, and her income drops to ₹1,50,000 a year in a single step. That is a ₹60,000-a-year cut — nearly 29% of her income gone overnight, and it stays gone.

Notice what makes it dangerous: everything matures on one day, so the whole ₹30,00,000 is exposed to the interest rate on that one day. If that day happens to fall in a low-rate trough, the entire income drops together. The fix, then, isn't cleverer forecasting of rates — nobody can time the cycle (Lesson 9 said so plainly). The fix is to stop letting all the money ride on a single future date.

Here is the same ₹30,00,000, currently earning ~7% (₹2,10,000 a year), shown two ways and across two possible futures. One way is the single long FD. The other is a ladder — several bonds with staggered maturities; here, five equal rungs (pieces) of ₹6,00,000 maturing in years one through five, which we'll build properly in a moment. Watch what each does if rates fall, and — the part people forget — if rates rise.

Read it honestly. If rates fall, the single FD actually stays higher for longer — it's locked at 7% for the full five years — and then drops off a cliff to ₹1,50,000 all at once. The ladder instead glides down in five gentle ₹12,000 steps to the same floor, because only one ₹6,00,000 rung reprices each year. If rates rise, the story flips: the single FD is stuck at 7% while the market pays more, and only jumps at maturity; the ladder climbs a rung at a time, ₹2,10,000 towards ₹2,70,000, catching the rise early.

A bond ladder is the plainest idea in fixed income. Instead of putting a lump into one instrument, you split it into several — each maturing a year (or a few years) after the last. Each piece is a rung. As the nearest rung matures, you either spend the cash or reinvest it into a fresh rung at the top of the ladder — the longest date. Do that year after year and the ladder “rolls”: something always comes due, and you're always reinvesting only a small slice, at a spread of different years' rates.

• Rung — one piece of the ladder: a single bond or FD with its own maturity date. Five rungs of ₹6,00,000 make a ₹30,00,000 ladder.
• Laddering — the act of staggering the maturities so one rung comes due each year, then rolling the matured rung to a new long rung.
• What it defeats — reinvestment risk (only ~1/5 reprices a year) AND a liquidity crunch (cash arrives every year without breaking anything).

The instruments that make good rungs are exactly the ones you already met. Here is the menu Lakshmi is choosing from, at today's FY2025-26 rates — with the honest point flagged up front: the highest genuinely-safe yields are not the government bond, they're the small-savings schemes.

This laddering is precisely what a good fixed-income manager does with a client's money — and precisely what a lazy or conflicted one doesn't. Here's the move stripped of mystique, with the do-it-yourself version and the tell that your manager isn't earning the fee.

Now we assemble it. Of her ₹95,00,000, Lakshmi puts ₹75,00,000 — seventy-five lakh — into the fixed-income sleeve, and keeps ₹20,00,000 in a growth sleeve (equities/hybrids) that we'll size properly in Lesson 40. Why keep any growth at 64? Because a retirement can run 25–30 years, and inflation will roughly halve the value of a fixed rupee over that time — a little growth is what stops her outliving her money. The ₹75,00,000 sleeve is arranged like this:

Trace the logic of each piece by its job. The SCSS holds ₹30,00,000 — the scheme's per-person ceiling — at 8.2%, paying ₹2,46,000 a year in quarterly instalments of ₹61,500: this is her income backbone, government-backed. The FRSB holds ₹10,00,000 at 8.05%, paying ₹80,500 a year every six months: her longest, floating anchor, which quietly rises if rates rise. The G-sec/FD ladder holds ₹30,00,000 in five ₹6,00,000 rungs at about 6.7%, paying ₹2,01,000 a year and — crucially — handing back ₹6,00,000 every year to spend or re-rung. And ₹5,00,000 sits in a liquid fund at ~6%: not for its ₹30,000 of yield but as her cash floor and dry powder.

So the whole sleeve throws off ₹5,57,500 a year — about ₹46,458 a month — at a blended 7.43%. Compare that with the tidy alternative of one long FD: the same ₹75,00,000 in a single top FD at ~6.45% would pay ₹4,83,750 a year. The ladder earns ₹73,750 more a year — and here is the honest reason why. It is not because the government bonds beat the FD; they don't. It is almost entirely because SCSS (8.2%) and the FRSB (8.05%) out-yield deposits, and the ladder simply lets her hold as much of them as the rules allow, with the rest structured so no single rate move can knock out her income.

A ladder rung can be a direct bond you buy yourself, a debt fund, or a plain FD. Beginners want to know which is “best.” The honest answer is that there is no best — there is a trade-off, and each of the three wins on a different axis. Put the same ₹10,00,000 into each and lay them side by side.

One change quietly rewired this whole comparison. Before April 2023, debt funds enjoyed a tax advantage (indexation) that FDs never had. That is gone for units bought on or after 1 April 2023: their gains are now taxed at your slab, just like FD interest and bond coupons. So the debt fund's remaining edge is narrower and subtler — its tax is deferred until you redeem, and you choose when that happens — not a lower rate. We'll weigh the full after-tax ranking next.

You don't keep the yield on the label — you keep what's left after tax. For fixed income the rule is now blunt: interest and gains on FDs, bonds, SCSS, the FRSB and post-2023 debt funds are all taxed at your income-tax slab. There's no special low rate for “long-term” debt any more. That means the after-tax ranking depends heavily on your slab: a 30%-slab professional like Suresh keeps far less of an FD's 6.45% than Lakshmi, who — as a senior on a modest income — pays little tax and even gets an extra ₹50,000 interest deduction (80TTB) under the old regime.

The other rule for choosing a rung is duration-matching, which you met with a single bond in Lesson 32: match the length of what you buy to when you'll spend the money. Money for a fee due in three years belongs in a 3-year rung, not a 10-year bond you'd have to sell early into an uncertain price. A ladder is just duration-matching done across many dates at once — every rung matched to a future need or a rolling reinvestment.

Lakshmi lands near 79% fixed income because she is 64, very cautious, and living on the money. That is not your number. The share rises with age and as a goal approaches — but it's a starting point to adjust, never a rule, and one big input is usually already sitting in your account.

Two adjustments the bands can't make for you. First, risk need (Lesson 6): if a goal is already funded, dial fixed income up — you've won, so stop taking risk you don't need to. Second, and easily missed: your EPF and PPF are already fixed income. They are safe, interest-bearing, government-linked debt. Before you buy a single new bond, count them — most salaried savers already hold a bigger bond allocation than they realise, and need less new debt than a glossy chart suggests.

Follow the moderate household we've been building alongside — Rohan and Meera Iyer, ~₹30 LPA between them, a portfolio of about ₹35,00,000. This is the last fixed-income block before the Lesson 40 capstone, and it makes the previous point concrete: their debt sleeve was mostly there already.

Their ~30% debt sleeve (₹10,50,000) is their EPF (₹6,00,000) plus their PPF (₹3,00,000) — both already owned, both already fixed income — and just one fresh purchase: a ₹1,50,000 target-maturity debt fund dated to their daughter's college. Naming the sleeve, not buying a pile, was most of the work. Aarti, 24 and starting from zero, is the opposite dial: her debt sleeve is deliberately thin, mostly her EPF, because a 35-year horizon can ride equity's swings. Same lesson, two answers — the right debt share is set by your horizon and your nerves, and the whole mix is sized at Lesson 40 · Putting It All Together.

Everything you just learned is also a scam detector. The single most targeted person in Indian investing is a retiree living on interest, tired of ~6.5% FDs — and there is a whole industry selling them a “safe, guaranteed” escape from that rate. Here's how to see through it in thirty seconds, using only the safe ceiling you now know.

Maybe none of this was you five years ago. Maybe your entire fixed income is one big FD that all matures on the same day, or a debt fund a “relationship manager” signed you into whose name you couldn't explain. That is not a failure. It is where almost everyone's safe money starts — as an accidental pile, not a plan.

You don't undo anything in a hurry. You re-shape it, one maturity at a time: when the FD next comes due, split it into a 3–5 rung ladder instead of renewing the whole sum; count the EPF/PPF you already own as the ballast it is; and match each new piece to a date you'll actually spend it. A pile becomes a plan gradually, and there is no penalty for having been sensible while you learned. (And if that debt fund was mis-sold as “as safe as an FD but higher-returning,” a note on SEBI SCORES protects the next person who trusts the same desk.)

• “What's a bond ladder, in one line — and is it worth the effort?” Several bonds/FDs maturing in successive years, so one comes due each year. Worth it if you're living on the income or hold a large sum; if you just want simple, one target-maturity fund or a two-rung FD split does most of the job.
• “Direct bond, debt fund, or FD — which should I pick?” The one whose strengths fit the rung: a direct G-sec to lock a long, sovereign-safe yield at size; a debt fund for hands-off, liquid, tax-deferred money; an FD for a small guaranteed sum (keep ≤₹5 lakh per bank) or a senior's rate bump.
• “How much of my money should be fixed income?” Roughly rising with age — ~10–25% when young, ~40–60% near retirement, ~60–80% in retirement — but count your EPF/PPF first, and dial up if your goal is already funded.
• “What happens to my FD income if rates fall?” If it's one big FD maturing together, your income can drop off a cliff at maturity. A ladder reprices only a fraction each year, so a fall bleeds in gently and a recovery can undo it.
• “Is a debt fund safe?” Safer than equity, not as certain as an FD. Its NAV can dip if rates spike or a bond it holds is downgraded. A short-duration or target-maturity fund holding high-grade paper is the calm end; a “credit risk” fund reaching for yield is not.
• “Do I even need bonds if I have EPF and PPF?” Those ARE your bond allocation — safe, interest-bearing debt. Many salaried savers need little extra fixed income until closer to a goal.
• “SCSS, FD, or the FRSB for a retiree?” If eligible, SCSS (8.2%) and the FRSB (8.05%) usually beat FDs on yield — SCSS up to its ₹30 lakh cap, the FRSB for money you won't need for 7 years. FDs fill the shorter, flexible rungs.
• “Can I lose money in a ‘safe' debt fund?” In the short run, yes — a sharp rate rise pushes bond prices (and the NAV) down, as the seesaw in Lesson 9 showed. Held to its horizon, a high-grade fund's income makes that back. Match the fund's duration to your horizon.
• “Isn't laddering a lot of admin?” Less than it sounds. Three to five G-secs on RBI Retail Direct plus a couple of FDs, reviewed once a year when a rung matures, is the whole job — and you can replace the effort entirely with one target-maturity fund per date.

Here's the sleeve made live. It opens on Lakshmi's ₹75,00,000 — SCSS, the FRSB, a five-rung G-sec/FD ladder and a liquid floor — and reproduces her blended 7.43% and ₹5,57,500 a year. Change the amounts, the yields, or the number of rungs and watch three things move: the blended yield, the income, and how little reprices each year. Then clear it and build your own — put your EPF/PPF in as debt, and see what your real fixed-income yield is.

Two things to notice as you play. First, pushing more into SCSS and the FRSB lifts the blended yield fast — those are the high-safe-yield seats — but both have limits (₹30 lakh and a 7-year lock), which is exactly why the rest is a ladder. Second, adding rungs shrinks the slice that reprices each year: at five rungs only ~8% of the sleeve is exposed to any one year's rate. That shrinking slice IS the reinvestment-risk defence, made visible.

You didn't build anything exotic. You took the pieces you already had — plus a scheme, a floating bond and a couple of government rungs — and arranged them so income arrives steadily, a rate fall can't knock it out at once, and there's dry powder to buy the next dip. That's a fixed-income portfolio. Here are the new words, in one line each.

• Fixed-income sleeve — the debt part of your money (FDs, bonds, schemes, debt funds) treated as one deliberate block.
• Reinvestment risk — the danger that money coming back to you (a matured FD or bond) can only be re-lent at a lower rate than before.
• Bond ladder — several bonds/FDs maturing in successive years so one comes due each year.
• Rung — one piece of a ladder: a single bond or FD with its own maturity date.
• Laddering — staggering maturities so a rung matures each year, then rolling it to a new long rung.
• Dry powder — the safe reserve you deliberately keep so you can sell it to buy equities cheap after a crash.
• Duration-matching — buying a bond/FD whose length matches when you'll actually spend the money.
• Direct-bond vs debt-fund vs FD trade-off — no single winner: control/safety/size vs liquidity/hands-off/tax-deferral vs guarantee/simplicity.
• Target-maturity fund — a debt fund with a fixed end date that rolls down and behaves like a bond held to maturity.
• Barbell — a ladder cousin holding mostly very short + very long bonds; named here only so the word can't impress you.
• Blended yield — the weighted-average yield of the whole sleeve: total annual income ÷ total invested.
