23Why Every Country Has Its Own Money
There are about 180 currencies for 195 countries. This looks inefficient. It is not — and the countries that gave up their own currency have generally paid a heavy price for it.
Four reasons, in descending order of importance.
1. A currency is a shock absorber
This is the real answer, and everything else is secondary.
Suppose a country's main export collapses in price. Its people are now genuinely poorer. That adjustment has to happen somehow. There are exactly two mechanisms.
With your own currency: the currency falls. Imports become expensive, exports become competitive, and the adjustment is spread across everyone simultaneously and automatically. It hurts, but it happens in weeks and nobody has to be fired for it.
Without your own currency: the adjustment must come out of wages and jobs directly. Employers must cut pay or sack people. Because wages are famously "sticky downward" — people resist pay cuts fiercely — the adjustment comes mostly through unemployment, and it takes years instead of weeks.
A currency is like the suspension on a car. The road is bumpy either way. With suspension, the bumps are absorbed and the passengers are shaken. Without suspension, the bumps go straight into the chassis and something breaks.
Greece 2010–16 is the demonstration. It could not devalue because it used the euro, so its economy shrank by about a quarter and youth unemployment passed 50 per cent. Iceland, hit by a banking collapse that was proportionally far worse in 2008, devalued the króna by about 50 per cent and had recovered within four years. Same crisis type, opposite outcome, and the difference was having your own money.
2. Monetary sovereignty
Your own currency lets you set interest rates for your economy, act as lender of last resort to your own banks, and — crucially — borrow in money you can create. A government that borrows in its own currency cannot be forced into default by a foreign creditor. Japan has debt above 250 per cent of GDP and has never faced a crisis, because it owes yen. Sri Lanka defaulted in 2022 on about $50 billion, because it owed dollars.
3. Seigniorage
Printing money is profitable. The RBI's surplus transfer to the Government of India has run into the hundreds of thousands of crores in recent years. Give up your currency and you hand that revenue to someone else.
4. Identity and politics
Real, if secondary. A currency carries national symbols and is a daily statement of sovereignty. Note that the rupee sign ₹ was adopted only in 2010, and the debate about it was substantially about identity rather than economics.
When countries give it up
Table 23.1 — Countries without their own currency, and why
| Arrangement | Examples | Why they did it | What it cost |
|---|---|---|---|
| Full dollarisation | Ecuador (2000), El Salvador (2001), Panama, Zimbabwe (2009–19) | Own currency had already been destroyed by hyperinflation | No monetary policy, no lender of last resort, all seigniorage to the US |
| Currency board | Hong Kong, Bulgaria, formerly Argentina (1991–2001) | Import US credibility to kill inflation | Argentina's board collapsed in 2001 with a 60% devaluation, a default and a 40% poverty rate |
| Monetary union | Eurozone (20), CFA franc zone (14 African states), Eastern Caribbean | Reduce trade costs, import stability | Greece 2010–16; the CFA franc is still pegged to the euro with French involvement, a live political controversy |
| Hard peg | Saudi Arabia, UAE, Nepal (to INR), Bhutan (to INR) | Simplicity for a commodity or small economy | Interest rates set abroad; Gulf states must follow the Fed even in a domestic downturn |
In 2000, after the sucre lost 75 per cent of its value in a year and the banking system collapsed, Ecuador adopted the US dollar outright. Inflation fell from 96 per cent to single digits within three years. On that measure it worked.
The costs arrived later. Ecuador cannot devalue, so when oil prices fall — and it is an oil exporter — the adjustment comes entirely through wages and public spending. It has no lender of last resort, so its banks must self-insure. It earns no seigniorage. During COVID it could not conduct any monetary stimulus at all and had to default on its external debt.
Dollarisation is a decision taken by countries that have already lost the ability to run their own monetary policy credibly. It is a confession, not a strategy.
24How an Exchange Rate Is Actually Set
Nobody decides that a dollar is worth ninety-five rupees. It emerges from about $9.6 trillion of daily trading, of which only a small fraction has anything to do with buying goods.
An exchange rate is a price, and like any price it is set where supply meets demand. The question is: who is supplying and demanding rupees, and why?
Table 24.1 — What creates demand for and supply of rupees
| Demand for rupees (rupee strengthens) | Supply of rupees (rupee weakens) |
|---|---|
| Foreigners buy Indian goods — software, pharmaceuticals, textiles, engineering | India buys foreign goods — crude oil, gold, electronics, coal, edible oil |
| Foreign investors buy Indian shares, bonds or companies | Indian investors and firms invest abroad |
| Remittances from the ~18m Indians working overseas (~$135bn a year, the world's largest inflow) | Indians travelling, studying and paying fees abroad |
| Tourists visiting India | Repatriation of profits and dividends by foreign firms |
| Speculators betting the rupee will rise | Speculators betting the rupee will fall |
| RBI buying rupees with its reserves | RBI selling rupees to build reserves |
Global daily foreign exchange turnover is roughly $9.6 trillion. Annual world merchandise trade is roughly $24 trillion — about $95 billion a working day.
In other words, currency trading is about 100 times larger than the trade it nominally serves. Exchange rates are therefore set overwhelmingly by financial flows, expectations and speculation, not by the trade balance. This is why a rupee can fall on a day when India's exports were fine, and why "our exports are strong so the rupee should be strong" is not how it works.
The five exchange rate regimes
Free float
The market sets it; the central bank does not intervene. USD, EUR, JPY, GBP, AUD. Volatile but self-correcting.
Managed float ("dirty float")
The market sets the trend; the central bank intervenes to smooth volatility. India, Brazil, Indonesia, South Korea, Singapore. The RBI buys dollars when the rupee is strengthening too fast and sells when it is falling too fast — which is exactly what the $703bn of reserves is for.
Crawling peg
Fixed, but adjusted at a pre-announced rate. Used by countries with structurally higher inflation than their trading partners.
Hard peg
Fixed to another currency by policy. Saudi riyal at 3.75/USD since 1986; Hong Kong dollar in a band around 7.8; Nepalese rupee at 1.6 to the Indian rupee.
Currency board / dollarisation
The extreme: every unit issued must be backed by foreign currency, or the foreign currency is used directly.
What actually moves a currency
In rough order of importance over different horizons:
Days to weeks — interest rate differentials and risk sentiment. If US rates are 5% and Indian rates are 6%, money flows towards the higher return, adjusted for expected currency movement. When global markets panic, money flows to the dollar regardless of rates.
Months — the current account and commodity prices. For India, crude oil is the dominant single variable. A $10 rise in the oil price costs India roughly $13–15 billion a year in extra imports and puts direct downward pressure on the rupee.
Years — inflation differentials. If India's inflation averages 5% and America's 2%, the rupee must lose roughly 3% a year against the dollar just to keep Indian goods equally competitive. This is the single biggest reason the rupee has depreciated for eight decades, and it is not a sign of failure — it is arithmetic.
Decades — productivity growth. Countries whose productivity grows faster than their trading partners' tend to see their real exchange rate appreciate.
Imagine two shops selling the same thing. Indian prices rise 5 per cent a year; American prices rise 2 per cent. After ten years Indian goods have become about 34 per cent more expensive in their own currency terms.
If the exchange rate did not move, nobody would buy Indian goods. So the exchange rate moves: the rupee falls by roughly the inflation gap, restoring the balance.
The rupee falling against the dollar is not primarily a verdict on India's economy. It is mostly a verdict on the inflation difference between the two countries. A country can grow fast and still see its currency depreciate. India has been doing exactly that for thirty years.
This also tells you what would actually strengthen the rupee: not slogans, but persistently lower inflation and faster productivity growth than the United States. There is no shortcut.
Politicians in every country treat the exchange rate as a scoreboard. It is not.
Switzerland has an extremely strong franc and a small, specialised economy. Japan's yen collapsed from 110 to 155 per dollar between 2021 and 2024 while the Nikkei hit an all-time high. China deliberately kept the yuan weak for two decades and became the workshop of the world.
A weak currency helps exporters and hurts importers and consumers. A strong currency does the reverse. Which is better depends entirely on what your economy needs. For a country trying to build a manufacturing base and create jobs for a million new workers a month, a competitive currency is generally an asset, not a humiliation.
What genuinely matters is not the level but the volatility. Businesses can plan around ₹95 or ₹75. They cannot plan around a rate that moves 15 per cent in a quarter. This is exactly why the RBI targets stability rather than a number, and why it is right to.
25Purchasing Power Parity Explained
India's economy is either the fourth largest in the world or the third, depending on which ruler you use. Both figures are correct. Knowing which to use, and when, is one of the most useful things in this report.
Start with the simplest possible version of the idea.
Suppose a shirt costs $20 in New York and ₹800 in Delhi. If ₹800 buys the same shirt as $20, then in shirt terms the "true" exchange rate is ₹40 to the dollar. But the market rate is ₹95. The rupee is therefore undervalued relative to what it can actually buy at home — by a factor of more than two.
That factor is what Purchasing Power Parity measures.
Two different questions, two different answers.
Question 1: "How much oil can India buy?" Use the market exchange rate. Oil is priced in dollars on a world market. India must earn actual dollars. India's nominal GDP of about $4.3 trillion is the relevant number.
Question 2: "How well do Indians live? How much stuff does India actually produce and consume?" Use PPP. Most of what an Indian buys — rent, food, transport, haircuts, healthcare, education — is produced locally and is far cheaper than the exchange rate implies. India's PPP GDP of about $18.9 trillion is the relevant number.
Neither number is fake. They answer different questions. The error is using the flattering one for everything.
Figure 5. The same ten economies, measured two ways. India's ratio of about 4.4× is among the largest in the world — meaning Indian prices are roughly a quarter of American prices for a comparable basket. Note that the US bars are identical by construction: PPP is measured relative to the United States. Source: IMF World Economic Outlook, 2026 estimates.
Table 25.1 — When to use which measure
| Use nominal (market rate) for… | Use PPP for… |
|---|---|
| Importing oil, gold, semiconductors, aircraft | Comparing living standards |
| Repaying foreign-currency debt | Comparing the real size of economies |
| Military hardware purchases from abroad | Comparing domestic military manpower and production |
| IMF quotas, sovereign credit ratings | Measuring poverty and inequality across countries |
| Foreign investment flows | Comparing productivity per worker |
| Anything crossing a border | Anything staying inside a border |
The Big Mac Index
The Economist invented this in 1986 as a joke and it has become a genuinely useful teaching tool. A Big Mac is made of roughly the same ingredients everywhere, with roughly the same process, so comparing its price across countries gives a rough PPP reading. (In India, where the Maharaja Mac replaces beef, the comparison is adjusted.)
The logic: if a burger costs $5.80 in the US and ₹250 in India, the implied rate is ₹43 to the dollar. The actual rate is ₹95. The rupee is therefore "undervalued" by roughly 55 per cent on this measure.
PPP figures are used dishonestly more often than almost any other statistic, in every country. Four things they do not mean:
- It does not mean India can buy $18.9 trillion of anything. India can spend $4.3 trillion internationally. PPP dollars do not exist; you cannot pay Saudi Aramco in them.
- It does not mean Indians are three times richer than the nominal figure suggests in any sense that involves imported goods. An iPhone costs the same in dollars everywhere. Petrol tracks the world crude price. A foreign university degree is priced in dollars.
- It does not make per-capita comparisons flattering. India's PPP GDP per capita is roughly $13,000 against about $89,000 for the United States — a gap of nearly seven times, even after the PPP adjustment.
- PPP conversion factors are estimates, not measurements. They come from the World Bank's International Comparison Program, which surveys prices every six years. Between rounds, figures are extrapolated. Revisions have moved country rankings before.
The two per-capita figures are the honest ones and they tell the real story: India is a very large economy composed of a very large number of people who are not yet individually prosperous. Both halves of that sentence matter for everything in Part VII.
| $4.3tn | $18.9tn | ~$2,900 | ~$13,000 |
|---|---|---|---|
| Nominal GDP (4th–6th in the world, depending on the source) | PPP GDP (3rd in the world) | Nominal GDP per capita (~140th in the world) | PPP GDP per capita (~125th in the world) |
26Why Poor Countries Are Cheap
A haircut costs ₹150 in Lucknow and $45 in Chicago. The barber's skill is comparable, the scissors are similar, the time taken is the same. There is a precise economic reason for the difference, and it explains most of what PPP measures.
The explanation is called the Balassa–Samuelson effect, after the two economists who described it independently in 1964. It sounds intimidating and is actually simple.
Step 1. Divide the economy into two kinds of things. Tradables can be shipped: steel, phones, shirts, software. Non-tradables cannot: haircuts, restaurant meals, rent, school fees, bus rides, domestic help.
Step 2. Tradables have roughly one world price. A tonne of steel costs about the same everywhere, because if it were cheaper in India, buyers would ship it from India until the prices converged.
Step 3. Rich countries are rich because their workers are much more productive in tradables. An American factory worker with modern machinery produces far more per hour than an Indian worker with older equipment. So American manufacturing wages are much higher.
Step 4. Here is the key move. An American barber is not more productive than an Indian barber — one head at a time in both countries. But the American barber must be paid something close to what he could earn in a factory, or he would go and work in one. So the American barber earns a high wage he did not earn through productivity.
Step 5. Therefore haircuts, rent, restaurant meals and every other non-tradable are expensive in rich countries and cheap in poor ones — even though the service is identical.
Figure 11. Comparative price levels for a common basket, with the United States set to 100. India sits around 38, meaning the same basket costs roughly 38% of the American price. The pattern is almost perfectly correlated with GDP per capita — which is exactly what Balassa–Samuelson predicts.
Why this matters, practically
It explains India's cost advantage in services. An Indian software engineer's output — code — is perfectly tradable and worth the same anywhere. But the engineer lives in an economy where rent, food and transport are cheap, so a globally competitive salary in Indian terms is a fraction of the American equivalent.
India's entire IT services industry, worth around $250 billion in exports, rests on this arbitrage. So does global capability centre growth, and increasingly pharmaceutical and engineering R&D.
It predicts what happens as India grows. As Indian manufacturing productivity rises, manufacturing wages rise, which drags service wages up, which raises the domestic price level, which causes the real exchange rate to appreciate. India's cost advantage will erode — and that erosion is a symptom of success, not failure. China lived through exactly this between 2005 and 2020, which is why low-end manufacturing has been leaving China for Vietnam, Bangladesh and India.
It warns against a policy error. Because the effect predicts real appreciation as a country develops, governments sometimes try to force the currency up to signal success. This kills the tradable sector before productivity has caught up — a mistake made by several Latin American economies and, in a different form, by Britain in 1925.
Balassa–Samuelson has a direct implication for Part VIII. As India and other emerging economies converge on rich-country productivity, their real exchange rates appreciate and their share of world GDP measured at market rates rises much faster than their PPP share.
India's nominal GDP is about 3.6% of world output today but its PPP share is roughly 8.5%. Convergence would close that gap mechanically, without India growing any faster than it already is. This is the strongest structural argument for the rupee mattering more in 2050 — and it requires no policy at all, only continued growth.
27How Prices Are Actually Set Inside a Country
Take a single litre of petrol, a kilo of onions and a smartphone, and trace every rupee of the price. This chapter is the answer to "why does everything cost what it costs?"
There are essentially four price-setting mechanisms operating in any economy, and most goods involve more than one.
Mechanism 1: Cost-plus (most manufactured goods and services)
The seller adds up costs and applies a margin. The components:
- Raw materials — often set on world markets in dollars, so the exchange rate enters directly.
- Labour — set by local wages, minimum wage laws, and how scarce the skill is.
- Energy and transport — diesel, electricity, freight. In India this is a large share, and it is why fuel prices affect everything.
- Land and rent — set by local scarcity, which is why the same shirt costs more in a Mumbai mall than a Nagpur market.
- Capital costs — interest on borrowing, which is set by the central bank.
- Taxes — GST, customs duty, cess, state levies.
- Margin — determined by competition. This is the only part the seller freely chooses, and competition is what constrains it.
Mechanism 2: Market-clearing (commodities, produce, shares)
Nobody sets the price of onions. It emerges from how many onions arrived at the mandi and how many buyers turned up. This is why food prices are volatile and why a bad monsoon or an unseasonal rain can move India's headline inflation by a full percentage point in a month.
Mechanism 3: Administered prices (the state decides)
A substantial part of the Indian price structure is set by government, not markets:
Table 27.1 — Administered and influenced prices in India
| Price | Who sets it | Mechanism |
|---|---|---|
| Minimum Support Price for 23 crops | Union Government, on CACP advice | Guaranteed floor price for procurement; anchors wheat and rice markets |
| Retail petrol & diesel | Oil marketing companies, with government influence | Nominally deregulated since 2010/2014; in practice prices are frozen around elections and the state-owned companies absorb the difference |
| Electricity tariffs | State Electricity Regulatory Commissions | Cross-subsidy: industry pays above cost so farmers and households pay below |
| Essential medicines | NPPA under the DPCO | Ceiling prices on ~380 formulations |
| Rail passenger fares | Ministry of Railways | Held below cost; freight cross-subsidises passengers |
| Sugar (fair & remunerative price) | Union Government | Mills must pay a set price to cane farmers |
Mechanism 4: Market power (the seller decides)
Where competition is weak — a patented drug, a monopoly port, a dominant platform — the price is set by what buyers will bear, not by cost. This is why competition law exists.
Approximate breakdown at a retail price near ₹95 per litre:
| Component | Approx. ₹/litre | Share | Set by |
|---|---|---|---|
| Crude oil cost (landed) | 34 | 36% | World market, in dollars × exchange rate |
| Refining, freight, OMC margin | 7 | 7% | Refiners |
| Central excise duty | 20 | 21% | Union Government |
| State VAT | 16 | 17% | State Government |
| Dealer commission | 4 | 4% | Negotiated |
| Remaining costs & margins | 14 | 15% | Mixed |
Roughly 38 per cent of the pump price is tax. This is why petrol costs different amounts in different Indian states with identical crude — and why fuel prices barely fell when crude collapsed in 2020: governments raised excise to capture the difference. Fuel taxation is one of the largest single revenue sources for both the Centre and the states, which is also why petrol and diesel remain outside GST.
Six reasons, and they apply to every product on earth:
1. Local wages. Everything embeds the cost of the people who made, moved and sold it. 2. Taxes. A car in Singapore costs several times the Indian price almost entirely because of duties. 3. Tariffs and import duties. India's duties on gold, cars and electronics are deliberately high to protect domestic industry and manage the trade deficit. 4. Transport and distance. Landlocked and remote countries pay more for everything. 5. Subsidies. Diesel, fertiliser, LPG and food in India are sold below cost, with the state paying the difference. 6. Competition. Where a market has three suppliers, prices are higher than where it has thirty.
When a government caps a price below the cost of supply, sellers do not simply accept a loss. They reduce quality, sell less, exit the market, or divert supply to a black market where the true price prevails.
Diocletian tried it in 301 CE with the death penalty attached, and it failed. Venezuela tried it from 2003, and supermarket shelves emptied. India's own experience with sugar controls, drug price caps and electricity tariffs shows the same pattern in milder form: capped tariffs have left state electricity distribution companies with accumulated losses running into lakhs of crores, which ultimately taxpayers pay.
This is not an argument that all price intervention is wrong — essential medicines are a reasonable case for a ceiling, and the MSP system has genuine food-security logic. It is an argument that a price is information, and suppressing the information does not remove the underlying scarcity. It only moves who bears it, usually onto the state's balance sheet, usually invisibly.
28Inflation: What It Is and Who It Robs
Inflation is not "prices going up". It is the value of money going down. The difference matters, because it tells you who is responsible and who pays.
If the price of tomatoes rises because of a bad harvest, that is a relative price change — tomatoes have become scarce. If the price of tomatoes, shirts, rent, school fees, cement and haircuts all rise together, tomatoes have not become scarce. The rupee has become less valuable. That is inflation.
The three causes
Demand-pull
Too much money chasing too few goods. Happens when incomes or credit grow faster than production. The classic post-COVID example: stimulus payments plus supply chains that could not respond.
Cost-push
The cost of producing everything rises — energy, wages, imported inputs. The 1973 oil shock, and in India, any large depreciation of the rupee or spike in crude.
Expectations
The self-fulfilling one, and the one central banks fear most. If everyone expects 8 per cent inflation, workers demand 8 per cent raises and firms set prices 8 per cent higher in advance. Inflation then happens because it was expected. This is why a central bank's credibility is a real economic asset.
How India measures it
Table 28.1 — India's price indices
| Index | What it measures | Weight of food | Used for |
|---|---|---|---|
| CPI (Consumer Price Index) | Retail prices paid by households | ~46% | The RBI's official target — 4% ±2% |
| WPI (Wholesale Price Index) | Prices at the wholesale/producer stage | ~24% | Business cost pressure; no services included |
| Core CPI | CPI excluding food and fuel | 0% | Underlying trend, stripped of volatility |
| GDP deflator | Prices across the whole economy | n/a | Converting nominal GDP to real GDP |
The 46% food weight is the single most important number here. It means Indian headline inflation is driven by the monsoon to a degree unimaginable in a rich country, where food is 10–15% of the basket.
The CPI is a weighted average of a basket meant to represent an average household. You are not the average household.
If you rent in a metro, education and rent may be 40 per cent of your spending, and both have been rising faster than the index. If you own your home and grow some of your food, your personal inflation is far lower. If you have a child in private school and a parent needing medical care, your inflation may be double the headline.
So when the government reports 4 per cent and you feel 9 per cent, both can be true. The index is not lying; it is describing a household that does not exist.
Who wins and who loses
Table 28.2 — The distribution of inflation
| Winners | Losers |
|---|---|
| Borrowers — you repay a fixed loan with cheaper money. A ₹50 lakh home loan taken in 2015 is much easier to service in 2026 rupees | Savers with fixed deposits — 6.5% interest against 6% inflation is a real return of half a per cent, before tax |
| Governments — the largest borrowers in most economies; inflation erodes the real value of public debt and increases nominal tax revenue | Pensioners on fixed incomes — the purest victims, since their income does not adjust |
| Owners of real assets — land, property, gold, equities, which rise with the price level | Wage earners without bargaining power — informal sector workers, whose pay adjusts last if at all |
| Exporters, if inflation is accompanied by depreciation | Importers and anyone with foreign-currency obligations |
A government that cannot raise taxes politically, and cannot cut spending politically, has a third option: create money. Prices rise, the real value of its debt falls, and the cost is spread across everyone holding the currency.
Keynes described this precisely in 1919: "By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens... The process engages all the hidden forces of economic law on the side of destruction, and does it in a manner which not one man in a million is able to diagnose."
This is why central bank independence matters, and why India's move to a formal inflation-targeting framework in 2016 — 4 per cent CPI, with a tolerance band of 2 to 6 per cent, set in law and enforced by a Monetary Policy Committee — is among the more significant institutional reforms of the last decade. It is also why any proposal to weaken that independence, in any country, should be looked at very carefully.
India's worst inflation years: 1974–75 (~28%, after the oil shock and a failed monsoon), 1980 (~18%), 1991 (~13.9%), 2010–13 (~10% average). Since inflation targeting began in 2016, CPI has averaged roughly 5%. Hyperinflation records: Hungary 1946 (prices doubling every 15 hours), Zimbabwe November 2008 (79.6 billion per cent monthly), Yugoslavia 1994, Venezuela 2018–19.
29Central Banks and the Machinery of Interest Rates
Twelve people in a room in Mumbai, and twelve in a room in Washington, make decisions every six weeks that determine what a home loan costs on three continents. Here is how the lever actually works.
A central bank has one primary instrument: the price at which commercial banks can borrow reserves overnight. In India this is the repo rate; in the US, the federal funds rate. Everything else is transmission.
How the transmission works
1. The RBI's Monetary Policy Committee raises the repo rate from 6.00% to 6.50%. 2. Banks now pay more to borrow overnight, so they raise their own lending rates. Since 2019 most Indian floating-rate retail loans are linked directly to the repo rate, so this happens automatically. 3. Home loans, car loans and business loans become more expensive. Some borrowers postpone. 4. Deposit rates rise, so saving becomes more attractive relative to spending. 5. Total demand in the economy falls. 6. With less demand chasing the same goods, price rises slow. 7. Separately, higher Indian rates attract foreign capital, which strengthens the rupee, which makes imports cheaper, which reduces imported inflation.
Steps 1 to 6 take between six and eighteen months. This lag is why central banking is so difficult: you must act on a forecast, and you will be judged on an outcome you set in motion a year and a half earlier.
The RBI's toolkit
Table 29.1 — What the Reserve Bank of India actually controls
| Tool | What it is | Effect |
|---|---|---|
| Repo rate | Rate at which RBI lends to banks against securities | The main policy lever |
| Reverse repo / SDF | Rate at which RBI absorbs surplus bank funds | Sets the floor of the corridor |
| CRR — Cash Reserve Ratio | Share of deposits banks must hold with RBI (4%) | Directly removes lendable funds |
| SLR — Statutory Liquidity Ratio | Share of deposits in government securities (18%) | Creates captive demand for government debt |
| Open market operations | Buying/selling government bonds | Adds or drains liquidity |
| FX intervention | Buying/selling dollars from the $703bn reserves | Smooths the rupee |
| Macroprudential rules | Risk weights, loan-to-value caps, provisioning norms | Targets specific credit segments — used in 2023 to cool unsecured personal lending |
Why the Federal Reserve is India's second central bank
This is the practical consequence of everything in Parts II and III, and it deserves to be stated without euphemism.
When the Fed raises rates, dollar assets become more attractive. Foreign portfolio investors sell Indian bonds and equities and take the money home. The rupee falls. India's import bill — 85 per cent of its oil, most of its electronics, its gold — rises in rupee terms. Inflation rises. To defend the currency and contain inflation, the RBI must consider raising Indian rates even if India's domestic economy needs lower ones.
In 2013, when Fed Chairman Ben Bernanke merely mentioned that the Fed might slow its bond purchases, the rupee fell about 20 per cent in four months and the RBI raised rates into a slowing economy. India had done nothing wrong. The episode is remembered as the "taper tantrum", and India was one of the "Fragile Five".
India's central bank sets Indian interest rates. But it does so inside a room whose temperature is controlled by someone else. The RBI's independence is real and valuable, and it is exercised within constraints set in Washington by people whose legal mandate mentions only American workers and American prices.
This is the concrete, everyday meaning of dollar dominance for an Indian household. It is not abstract geopolitics. It is the reason your home loan EMI can rise because of a decision taken by people who have never heard of you and are not permitted, by their own law, to consider you.
India holds about $703 billion in foreign exchange reserves. These earn perhaps 2–4 per cent in US Treasuries and similar instruments. The same capital deployed in Indian infrastructure might earn a social return several times that.
The gap is the insurance premium India pays for not being inside the Federal Reserve's swap-line circle. A rough estimate: if the opportunity cost is 4 percentage points on $700 billion, the annual cost is on the order of $28 billion — comparable to India's entire annual health budget.
This is not an argument for holding fewer reserves; 1991 is why India holds them, and they have demonstrably worked. It is an argument for understanding that the current system has a price, it is paid in Indian rupees, and it is paid every single year. That is the honest case for caring about this subject.
