How Inflation Works: Why Aman's Bread Costs More Every Year

2.1 — ₹40, then ₹52

Riya went looking through old messages for something unrelated and found a photograph of a receipt from Aman's bakery, years old. The loaf she had bought that morning for ₹52 had cost ₹40 in the picture.

Same loaf. Same recipe, same weight, same shop. Thirty per cent more money for an identical object.

"That's inflation," Raj said, "and the thing to understand is that it isn't really a fact about bread. Aman didn't decide bread was worth more. It's a fact about the rupee — what it buys has quietly shrunk, and the price tag is just where you notice."

2.2 — What it is, and how India measures it

**Inflation** is the rate at which prices rise across an economy over time, which is the same thing as saying the rate at which a given amount of money buys less. It is not one product becoming dearer for its own reasons — it is a broad drift affecting bread, rent, fuel, clothing and nearly everything else together.

India's headline measure is the **Consumer Price Index (CPI)** — a representative basket of what a typical household actually buys, priced repeatedly and compared month to month. "Inflation is running at 5%" means that basket costs 5% more than a year earlier.

The **Reserve Bank of India** is formally tasked with keeping CPI inflation around **4%**, within a tolerance band of roughly **2% to 6%**. Readings persistently outside that band are treated as a problem requiring action — which is a sentence Riya would understand properly four chapters later.

2.3 — Why Aman raised his prices, in his own words

"People assume I put prices up because I can," Aman said. "Flour costs me more than last year. Electricity costs more. My rent went up. My bakers asked for more money and they were right to, because their rent went up too."

"So you raised prices to keep the same margin," Riya said.

"I raised prices to earn what I earned last year. If I'd held the price, I'd be baking the same bread for less money every year, which is a slow way of going out of business."

This is the mechanism from the inside. Every business is simultaneously somebody else's customer, so rising costs propagate through an economy rather than staying put — which is why inflation is broad rather than isolated.

2.4 — The raise that wasn't a raise

Riya had been rather pleased about her 5% salary increase that year until Raj asked one question.

"What was inflation over the same twelve months?"

She looked it up. Also roughly 5%.

"Then you didn't get a raise," he said. "You got a larger number that buys the same groceries. Which is not nothing — a zero per cent rise would have been a real pay cut. But you haven't moved forward."

This is the distinction between a **nominal** figure and a **real** one, applied to a salary instead of to GDP. A 5% rise against 2% inflation is a genuine 3% gain in purchasing power. A 5% rise against 6% inflation is a real-terms loss, regardless of how the payslip reads.

2.5 — The safe thing that wasn't safe from this

It was Riya who made the next connection, and she went quiet for a moment when she did.

"My bond," she said. "The flyover. It pays me 7% a year, fixed, exactly as promised. It's never missed a payment."

"Go on."

"If inflation's been running at five, then my seven per cent is really about two. I've been getting two per cent, not seven, for years. And I bought that thing *specifically* because it was the one asset that promised me something."

This is the honest and uncomfortable point about fixed-income investments. The coupon is contractual and will be paid — that part was never in doubt. But it is fixed in **rupees**, and the purchasing power of those rupees is not fixed at all. **The real return is the stated rate minus inflation**, and on a long-dated bond bought in a low-inflation period, that gap can quietly eat most of the return.

2.6 — So why not drive it to zero?

"Then inflation is just bad," Riya said. "Why doesn't the RBI simply target zero and be done with it?"

"Because the alternative is worse in ways that are less obvious." Raj thought about how to put it. "If prices are expected to *fall* next year, why would you buy anything today that you could buy cheaper in six months? Spending stops. And if spending stops, Aman's revenue stops, and then Aman's staff stop."

A low, steady, *predictable* rate of inflation is generally considered a feature of a healthy growing economy — it keeps money moving and gives businesses room to adjust prices and wages gradually. What causes genuine damage is not mild ongoing inflation but **sudden, unpredictable** inflation, which destroys the ability of households and businesses to plan at all. That is why the target is around 4% rather than 0%.

2.7 — So who is actually in charge of this?

"You keep saying the RBI is responsible for it," Riya said. "Responsible how? It doesn't set the price of flour. It can't tell Aman what to charge."

"No. It has one main lever and it's an indirect one, and it's the same lever that moved your bond's price years ago when you tried to sell it early."

Riya remembered that afternoon perfectly — being quoted less than ₹10,000 for a certificate that said ₹10,000, and Raj telling her that rates had risen, and filing away the question of whose decision that actually was.

"That's one institution," Raj said. "There's a second one, with a completely different set of tools, and it announces what it's doing on the first of February every year in a speech the entire market stops to watch."
