Every year, UPSC Prelims throws at least 15 to 18 questions from Economy. And almost half of them test whether you truly understand basic economic terms — not complex theories. I have seen aspirants lose marks not because the question was hard, but because they confused one term with another. This article gives you 20 terms that keep appearing, defined in a way that actually sticks.
Where This Topic Sits in the UPSC Syllabus
Economic terminology falls under the broad umbrella of Indian Economy in the UPSC Prelims syllabus. These terms also appear across GS-III in Mains, particularly under topics like growth, development, budgeting, and monetary policy.
| Exam Stage | Paper | Syllabus Section |
|---|---|---|
| Prelims | General Studies Paper I | Indian Economy and issues relating to Planning, Mobilisation of Resources, Growth, Development |
| Mains | GS-III | Indian Economy — Growth, Development, Employment, Budgeting, Monetary Policy |
These terms are not tested in isolation. UPSC often wraps them inside a statement-based question where you must judge if a definition or relationship is correct. Knowing each term precisely is your best defence.
Terms Related to National Income and Growth
Gross Domestic Product (GDP) is the total market value of all final goods and services produced within a country’s borders in a given year. The word “final” is key here — intermediate goods like flour used by a bakery are not counted separately. India uses GDP at market prices as its primary measure since 2015.
Gross National Product (GNP) adds the income earned by Indian residents abroad and subtracts income earned by foreigners within India from GDP. Think of it this way — GDP counts by geography, GNP counts by nationality.
Net National Product (NNP) is GNP minus depreciation. Depreciation means the wear and tear of machines and equipment used during production. When you hear “National Income” in official documents, it usually refers to NNP at factor cost.
Per Capita Income is simply the national income divided by the total population. It gives a rough idea of average living standards but hides inequality completely. India’s per capita income crossed ₹2 lakh annually in 2026-26 estimates.
Terms Related to Government Budget and Finance
Fiscal Deficit is the difference between the government’s total expenditure and its total receipts excluding borrowings. In simple terms, it tells you how much the government needs to borrow in a given year. A high fiscal deficit means the government is spending far more than it earns.
Revenue Deficit is narrower — it is the gap between revenue expenditure and revenue receipts only. It shows that the government’s regular income is not enough to cover its day-to-day spending, which is a sign of poor fiscal health.
Primary Deficit is fiscal deficit minus interest payments. It tells you what the borrowing situation would look like if the government did not have to pay interest on past loans. This term appears less frequently but UPSC has tested it.
Current Account Deficit (CAD) refers to a situation where a country’s total imports of goods, services, and transfers exceed its total exports. India runs a CAD most years because our oil import bill is massive. CAD is part of the Balance of Payments, not the government budget — aspirants often confuse this.
Terms Related to Monetary Policy and Banking
Repo Rate is the interest rate at which the Reserve Bank of India lends short-term money to commercial banks against government securities. When RBI raises the repo rate, borrowing becomes expensive, and spending in the economy slows down. This is RBI’s primary tool to control inflation.
Reverse Repo Rate is the rate at which RBI borrows money from commercial banks. Under the revised framework, the Standing Deposit Facility (SDF) rate has largely replaced the reverse repo rate as the floor of the interest rate corridor since April 2022.
Cash Reserve Ratio (CRR) is the percentage of a bank’s total deposits that must be kept with RBI as cash. Banks earn no interest on this amount. When RBI increases CRR, banks have less money to lend, which tightens liquidity.
Statutory Liquidity Ratio (SLR) is the percentage of deposits that banks must maintain in the form of gold, cash, or approved government securities. Unlike CRR, SLR assets can include securities — not just cash.
Open Market Operations (OMOs) refer to the buying and selling of government securities by RBI in the open market. When RBI buys securities, it injects money into the system. When it sells, it absorbs money. This is another tool to manage liquidity.
Terms Related to Prices and Inflation
Consumer Price Index (CPI) measures the average change in prices paid by consumers for a basket of goods and services over time. RBI uses CPI-Combined as the benchmark for its inflation targeting framework. The target is 4% with a tolerance band of plus or minus 2%.
Wholesale Price Index (WPI) measures price changes at the wholesale or producer level. WPI does not include services — only goods. The base year for WPI is currently 2011-12. WPI and CPI often move in different directions, which confuses students, but the reason is simple — they measure prices at different stages of the supply chain.
Deflation is a sustained decrease in the general price level. It sounds good but is actually dangerous because it discourages spending — people wait for prices to fall further. Japan experienced deflation for nearly two decades.
Terms Related to Trade and External Sector
Balance of Payments (BoP) is a systematic record of all economic transactions between residents of a country and the rest of the world during a given period. It has two main accounts — the current account and the capital account. The BoP must always balance in an accounting sense.
Foreign Direct Investment (FDI) is investment made by a foreign entity in a business where it holds at least 10% ownership stake. FDI is considered stable, long-term capital. India received over $70 billion in FDI in recent years, with services, computer software, and telecom as top sectors.
Foreign Portfolio Investment (FPI) involves foreign investors buying stocks, bonds, and other financial assets without seeking management control. FPI is considered “hot money” because it can leave the country quickly during uncertainty.
Most Favoured Nation (MFN) is a status granted under WTO rules. It means a country must treat all WTO members equally in terms of trade — the best tariff rate given to one must be given to all. India suspended MFN status to Pakistan in 2019 following the Pulwama attack.
Key Points to Remember for UPSC
- GDP measures production within borders; GNP measures production by nationals — learn to distinguish them using one-line definitions.
- Fiscal deficit includes borrowing needs; primary deficit strips out interest payments — UPSC loves to test this difference.
- CRR is kept as cash with RBI; SLR can include government securities and gold — they are not the same instrument.
- RBI uses CPI, not WPI, for inflation targeting under the flexible inflation targeting framework adopted in 2016.
- FDI is long-term and stable; FPI is short-term and volatile — questions often present them as interchangeable, which they are not.
- CAD belongs to Balance of Payments, not to the Union Budget — do not confuse it with fiscal deficit.
- MFN does not mean special treatment — it means equal, non-discriminatory treatment under WTO rules.
- Repo rate is for RBI lending to banks; reverse repo or SDF rate is for RBI borrowing from banks — the direction of money flow is what matters.
Knowing these 20 terms with clarity can directly help you attempt 8 to 10 Prelims questions with confidence. I suggest you make a one-page chart of all these terms with one-line definitions and revise it every week until the exam. Economy rewards those who are precise with language — build that precision now, and it will pay off on exam day.
