A Personal Ledger · Fixed Income, First Principles

The Price–Yield Seesaw

What actually happened when you bought a bond in the secondary market — and how to see a hidden markup with your own eyes.

Entry 01 · The Fixed Promise

The coupon is carved in stone. Everything else moves.

A bond like your EFSL NCD makes one unbreakable promise: it pays 9.21% of its face value, every year, until maturity. If the face value is ₹1,000 per unit, that is ₹92.10 per unit, per year — rain or shine, whether markets rise or fall.

Coupon · Never Changes ₹92.10 / yr per ₹1,000 face value

Hold that stamp in your mind. It never moves again for the rest of this page. What moves is the price you pay to receive it.

Entry 02 · The Seesaw

Yield is what you earn on what you paid.

The ₹92.10 payment is fixed — but your purchase price is not. Your real earning rate (yield) is simply that fixed payment divided by your price. Drag the slider below and watch the seesaw tilt. This is the entire principle, experienced directly:

Try it: pay more, earn less. Pay less, earn more.

The coupon (₹92.10) never changes — only your price does.

PRICE₹1,000
YIELD9.21%
Coupon fixed at ₹92.10
You Pay₹1,000
You Receive₹92.10/yr
Your Yield9.21%

At face value — you earn exactly the coupon rate.

The rule in one line
Price up → yield down. Price down → yield up. The seesaw never breaks, because the coupon at the centre never moves.
Entry 03 · Where the Fee Hides

A markup hides in the price, not on a receipt.

You know this pattern from the farm gate. Suppose the mandi rate for your crop is ₹100/kg. A trader buys at ₹100 and sells onward at ₹104. The final buyer never sees a "commission" line anywhere — the ₹4 was folded silently into the price.

Farmer sells at₹100/kg
Trader+₹4
Buyer pays₹104/kg
No receipt ever says "commission: ₹4." It lived inside the price.

Secondary-market bonds work exactly the same way. If the market was trading your EFSL units at ₹1,000 on your purchase date, and you were sold them at ₹1,020 — that ₹20 per unit was the intermediary's earning. It never appeared as a fee. It simply lowered your yield, quietly, via the seesaw you just operated above.

Entry 04 · The One-Comparison Test

How to see it with your own eyes.

The test requires exactly one comparison: what were other people paying for the same ISIN around your purchase date?

  1. Note your ISIN and your purchase price per unit from your contract note.
  2. Look up historical trades for that ISIN on the NSE or BSE debt-segment trade reports for dates around your purchase.
  3. Compare the traded prices against yours.
Outcome A · Fair Deal Your price ≈ market price. The intermediary's commission came out of Nuvama's own spread — it cost you little or nothing extra.
Outcome B · Embedded Markup Market traded meaningfully below your price. The gap was the markup — and it came out of your return, via a lower yield.
Entry 05 · On Paying a Professional

Knowing the price of trust is not distrust.

Paying a professional to lead, take responsibility, and stand by you if things go south is a legitimate trade — one many wise investors choose deliberately. Nothing on this page argues against it.

The purpose of the one-comparison test is narrower and simpler: to convert an invisible number into a known number. Once you know what the leadership costs, paying it becomes a choice you made — not a figure you never saw. That is the whole difference between delegation and blind delegation.

Entry 07 · The Intermediary's Ledger

Know the number before the handshake.

First, fix the roles in your mind — this is where the earlier confusion lived:

SellerNuvama
IntermediaryKaran
BuyerYou
Karan is the mandi trader — never a party on the contract note, which is exactly why his earning stays invisible.

Traditional commission bands · Indian market

Industry-pattern estimates, not knowledge of any specific arrangement. Use these as your pre-meeting calculator.

On a ₹45,00,000 secondary-market NCD deal

  1. Referral / sub-broker fee: 0.25% – 1.00% of invested amount → ₹11,250 – ₹45,000
  2. Embedded price markup (most common): 0.50% – 2.00% of transaction value → ₹22,500 – ₹90,000
  3. Combined typical zone: most retail deals of this size land around 0.5% – 1.5% total → ₹22,500 – ₹67,500

Before any future deal, run this in your head: investment × 1% is your anchor. On ₹45L, anchor = ₹45,000. Anything the intermediary discloses gets compared against that anchor — above it, you negotiate; near or below it, it's within market norms.

The negotiation skill, in four moves

Move 1, opened up · How anchoring actually works

The core law: a mind cannot ignore a number it has heard. Psychologists Tversky & Kahneman showed that even a random number changes people's later estimates. The first figure spoken in any negotiation becomes the anchor — the reference point every later number is judged against.

Why the brain obeys: judging "is ₹67,500 fair?" from nothing is hard work; the mind has no built-in scale for money. So it borrows the nearest scale available — whichever number arrived first — and then adjusts from it. The flaw: adjustment is almost always insufficient. People drift a little from the anchor, never all the way to the truth.

The mandi demonstration: a trader opens "gobhi ₹60/kg, best rate." You counter ₹80; he "concedes" ₹68 — and it feels like a win. But if that day's wholesale rate was ₹85, the whole dance happened on his ground. His opening number defined what winning felt like. Reverse it: the farmer who checked the rate board speaks first — "board says ₹85, mine's better, ₹90" — and now the trader is the one adjusting insufficiently around your anchor.

The three faculties the skill runs on — all already yours:

  1. Preparation (memory + arithmetic): an anchor works only if you carry a number into the room. Your verified 1% = ₹45,000 is that number. A defensible anchor beats an invented one.
  2. Initiative (composure): naming money first costs a moment of social discomfort; the one who hesitates cedes the frame. Calm delivery makes your anchor sound like a fact, not a bid.
  3. Discipline (emotional regulation): once your anchor is placed, go silent. The other mind is now adjusting around your number — extra talk only hands them material to re-anchor.

Note the rhyme with Entry 08: prepare the verified number, present it calmly, let it stand. Negotiation and verification are one skill wearing two coats.

1 · Anchor before he does. Walk in knowing the band (above). The person who names the reference range first controls the conversation.

2 · Ask in structure, not in suspicion. "What is the total cost to me — markup plus any referral fee — expressed as a percentage?" A percentage question is professional; a "how much did you make off me" question is personal.

3 · Trade volume for rate. Your leverage is repeat business. "I intend to route my fixed-income deals through you for years — at that volume, I'd expect the total cost per deal to sit at X%." Long relationships justify thinner margins; say so explicitly.

4 · Make disclosure the condition, not the request. The deal-by-deal rule below does this for you.

The affirmative statement · for Karan Puri, directly

Say it once, calmly, and let it stand

"Karan, I value this relationship and I intend for it to last years, not transactions. From here on, I have one standing condition: before every deal, you tell me in writing what you earn from it — markup, referral, or both, as a rupee figure or a percentage. I'm not asking because I object to you earning — a professional who leads and stays accountable deserves to be paid. I'm asking because I will not make decisions in the dark. Transparency is what makes me a long-term client instead of a one-time one. If the number is fair, you'll never hear a complaint from me. If it can't be shared, that itself tells me what I need to know."

Note what this statement does: it affirms his worth, converts disclosure into the price of your loyalty, and removes every escape route without a single accusatory word. His response — not the commission figure — becomes your real data point.

Entry 08 · The Verification Toolkit

Never hold a number you cannot reproduce yourself.

Entry 07 gave you an anchor — but an anchor someone else hands you is just another blind spot wearing a friendlier face. This entry is the machinery to reproduce every number from an independent source. That is the entire intelligence mindset, in one discipline.

The mindset: smart investors are not people who know more numbers. They are people who know where every number comes from — and can walk the trail without anyone's permission. The moment you can verify, an intermediary's only durable value becomes genuine service: sourcing, execution, accountability. Ignorance-dependence is fragile; service-dependence lasts.

Three independent checks · in order of authority

  1. Exchange trade reports — the ground truth.
    Every listed NCD trade must be reported to the exchange. NSE and BSE publish daily corporate-bond trade data: ISIN, traded price, traded yield. Search your ISIN for dates around any purchase. This is the market price no one can argue with — it verifies both a past deal and any anchor figure anyone (including an AI) hands you.
    Where: NSE → Market Data → Bonds/Corporate Bonds · BSE → Debt segment trade reports
  2. Competing quotes — the live band.
    Before any future deal, pull the same ISIN's offer yield from two platforms you have already vetted (Wint Wealth, GoldenPi, IndiaBonds). Three quotes on one ISIN = the market band. Karan's offer sits inside it, or it doesn't. The gap between platform quotes and exchange-traded prices is the intermediary margin — observed, not assumed.
  3. The paper calculation — yours alone.
    Exchange-traded yield − your purchase yield, × years to maturity ≈ what the deal cost you, per ₹100. Needs only your contract note, the exchange report, and the seesaw you already operate. No testimony required.

The standing discipline · before every future deal

The 3-source rule
No deal proceeds until the offered price has been checked against (1) exchange trade data, (2) at least one competing platform quote, and (3) your own yield calculation. Fifteen minutes of work. If all three agree the price is fair, proceed with full confidence — and tell Karan you checked. An intermediary who knows you verify treats you as a peer, permanently.

Note the shift this creates: Karan's confidence problem is solved too. A client who verifies and still chooses him is the strongest endorsement he can have. You are not auditing him into a corner — you are upgrading the relationship from dependence to partnership.

Entry 09 · The Coupon Verification Ritual

Thirty seconds a month: expected vs. received.

The machine's promise, in your numbers: 4,500 units × ₹1,000 face × 9.21% ÷ 12 months. Work it once by hand before using the calculator below — the arithmetic should become yours, not the page's.

Expected · Every Month ₹31,083.75 net of 10% TDS · gross ₹34,537.50
Corrected · TDS applies (my earlier note was outdated)
The old Section 193 exemption for listed demat NCDs was removed by Finance Act 2023 (effective 1-Apr-2023). Current rule: 10% TDS is deducted on the interest (20% if PAN invalid). Expected net monthly credit: ₹34,537.50 − ₹3,453.75 = ₹31,083.75. The deducted amount is advance tax — verify it appears in Form 26AS/AIS against your PAN, and it adjusts at ITR filing. A lesson kept deliberately visible: even this ledger's numbers obey the 3-source rule.

Entry 10 · The Market Log

Track the wobble. Your yield stands still.

Each time you check the screen price (ICICI Direct LTP), log it here. The page computes what that price means — for a new buyer, and for your notional exit — while your own numbers stay carved where June 30 left them: dirty price ₹1,010 · locked yield 9.12% · coupon 9.21% on face.

Who gains from fluctuations — a fact this log encodes
The issuer earns nothing when the screen price moves — their cost was fixed at issue. Price wobble is money changing hands between market participants (traders, intermediaries via markups). This log therefore tracks two honest quantities: the new-buyer yield at each logged price, and your notional gain/loss if you sold that day (4,500 units). Neither touches your monthly coupon.

Retrieval Practice · 8 Questions

1. The market price of your EFSL units rises to ₹1,080. Does a new buyer at that price earn more or less than your 9.21% — and why?

Less. The coupon is still ₹92.10, but they paid ₹1,080 for it → ₹92.10 ÷ ₹1,080 ≈ 8.53%. Price up, yield down — the seesaw tilted.

2. Where does an intermediary's markup usually hide in a secondary-market bond deal?

Inside the price itself — not as a visible fee on any receipt. Like the mandi trader's ₹4, it is folded into what you paid, silently lowering your yield.

3. What single comparison tells you whether you paid a fair price or an embedded markup?

Your purchase price vs. what other trades in the same ISIN executed at around your purchase date (NSE/BSE debt-segment trade data). Near market = fair; meaningfully above = markup from your return.

4. Why is relying on one advisor without independent verification a form of concentration risk?

Because every decision inherits the same single judgment — its flaws, biases, and incentives included. Ten bonds picked by one unverified mind is one bet made ten times. The single point of failure moved from the asset to the advisor.

5. In your EFSL deal, who was the seller, who was the buyer, and what exactly was Karan's role?

Seller: Nuvama (or its counterparty). Buyer: you. Karan: the intermediary/referrer — the mandi trader who stands between the parties, appears on no contract note, and earns from the flow. That absence from the paperwork is precisely why his earning stays invisible.

6. What is your mental anchor figure for total intermediary cost on a ₹45 lakh deal — and what do you do if the disclosed number sits above it?

Anchor: 1% = ₹45,000. Above it → negotiate, using long-term volume as your leverage. Near or below it → within market norms. And remember: his willingness to disclose is a more important data point than the number itself.

7. Name the three independent sources in your 3-source rule — and which one is the "ground truth" no one can argue with?

(1) Exchange trade reports (NSE/BSE corporate bond data), (2) competing platform quotes on the same ISIN, (3) your own yield calculation. The ground truth is the exchange trade report — actual executed prices, reported by regulation, independent of anyone's word including an AI's.

8. Why does the person who names a number first control the negotiation — and what is the one-word flaw in how minds adjust away from an anchor?

Because a mind cannot ignore a number it has heard — the first figure becomes the reference point all later numbers are judged against. The flaw: adjustment from the anchor is insufficient — people drift a little from it, never all the way to the truth. Which is why you walk in carrying your verified anchor (1% = ₹45,000), place it calmly, and go silent.
