🏛️ The economy and stocks: the RBI, inflation, growth, the rupee and bond yields

🎯 In 30 seconds: Share prices are tied to the economy through a few channels. The RBI's repo rate sets the cost of money, which changes both company profits and how much investors will pay for future profits. CPI inflation, published by MOSPI on the 12th of each month, is what the RBI is trying to keep near 4%. GDP and industrial production show how fast the economy is growing. The 10-year government bond yield is the safe return every share competes with. The rupee, crude oil and foreign investor flows add India-specific swings. This chapter shows how to read each official release yourself, instead of relying on someone's summary of it.

Why the economy matters to a share price

Think of the economy as the weather and listed companies as farmers. A skilled farmer still does worse in a drought, and a careless one can look good in a year of perfect rain. You cannot control the weather, but you can learn to read the forecast and know which crops it hurts.

The same economic news hits sectors differently. A rate cut helps banks, real estate and auto lenders more than IT exporters. A weaker rupee helps IT exporters and hurts oil importers. Sectors and the business cycle showed which sectors swing most. This chapter is about the signals themselves.

A note on numbers: this page deliberately does not quote today's repo rate, inflation or GDP growth. They change, and a stale number is worse than none. Every section tells you where to find the current figure on an official website.

The RBI and the repo rate

The Reserve Bank of India is the country's central bank. Since 2016, interest rate decisions have been made by a Monetary Policy Committee (MPC) set up under the RBI Act, 1934:

• Six members. Three from the RBI (the Governor, who chairs it, the Deputy Governor in charge of monetary policy, and one RBI officer) and three external members appointed by the central government for four-year terms. Each member has one vote; if the votes tie, the Governor has a casting vote.
• Meetings. The law requires at least four meetings a year. In practice the MPC has met about every two months, and the RBI publishes the schedule in advance.
• The target. The government sets the inflation target in consultation with the RBI: 4% CPI inflation, with a tolerance band from 2% to 6%. On 25 March 2026 the government retained this target for 1 April 2026 to 31 March 2031.
• Accountability. If average inflation stays above 6% or below 2% for three consecutive quarters, the RBI must write to the government explaining why, what it will do, and how long it expects to take.
• Minutes. The RBI publishes the minutes, including how each member voted and why, on the fourteenth day after each meeting.

The main tool is the policy repo rate: the rate at which the RBI lends money to banks overnight against government securities. When the RBI raises the repo rate, banks' cost of funds rises, and over the following months loan and deposit rates tend to rise too. When it cuts, the reverse.

The policy statement also states the MPC's stance (for example "neutral" or "accommodative"), which hints at the direction of future decisions. Markets often react more to the stance and the RBI's inflation and growth forecasts than to the rate decision itself, because the decision is usually expected.

How rates reach share prices

Interest rates touch share prices through three channels:

1. Company costs. Higher rates raise interest bills for companies with debt. A heavily borrowed infrastructure or real estate firm feels it at once.
2. Customer demand. Higher rates make home loans, car loans and business loans more expensive, so people and firms borrow and spend less. Banks lend less. Autos, real estate and consumer durables slow down.
3. The discount rate. A share is worth the future cash it will produce, valued in today's rupees. When safe interest rates rise, future cash is worth less today, so investors pay less for it.

A hypothetical example of the third channel. A company produces ₹100 crore of free cash flow and is expected to grow it 6% a year forever. One simple formula (the growing perpetuity, explained in Building a stock thesis) values it at next year's cash divided by (required return - growth):

One percentage point on the required return moved the value by 14% to 20%, with no change at all in the business. That is why a surprise in rates or bond yields can move the whole market in a day. Growth companies, whose cash is mostly far in the future, react most (see Growth vs value).

Inflation: reading the CPI release

The Consumer Price Index (CPI) measures the price of a basket of goods and services that households buy. It is compiled by the National Statistics Office in the Ministry of Statistics and Programme Implementation (MOSPI). This is the inflation measure the RBI targets.

• When: on the 12th of each month at 4:00 PM IST, for the previous month, or the next working day if the 12th is a holiday.
• New series: from the release of 12 February 2026, CPI uses base year 2024 = 100, with weights from the Household Consumption Expenditure Survey 2023-24, and groups items into 12 divisions following the international COICOP 2018 classification. It replaced the older 2012 series. If you compare with charts or articles from before 2026, check which series they use.
• What to read: the all-India year-on-year inflation rate for the combined (rural plus urban) index; food inflation, shown separately as the Consumer Food Price Index (CFPI); and the division-wise table, which shows whether the change came from food, housing, fuel or other items.

Food has a large weight in Indian CPI, so vegetable prices after a bad monsoon or a heatwave can swing the headline number. That is why analysts also look at core inflation: inflation excluding food and fuel. Core inflation is not a headline number in the CPI press release; analysts calculate it from the detailed indices, and their definitions vary. India also publishes a Wholesale Price Index (WPI), compiled by the Office of the Economic Adviser in the Ministry of Commerce and Industry, which tracks prices at the producer and wholesale level and often moves ahead of CPI for goods.

What matters for shares is inflation against expectations and against the RBI's target band. Inflation coming in well above forecasts raises the odds of higher rates, which usually weighs on rate-sensitive shares. Inflation falling toward 4% or below gives the RBI room to cut.

Growth: GDP, industrial output and jobs

Gross Domestic Product (GDP) is the value of all goods and services produced in the country. MOSPI publishes:

• Quarterly estimates about two months after each quarter ends. The 2026-27 advance release calendar, for example, lists 31 August 2026 for April to June and 30 November 2026 for July to September.
• Annual estimates, with provisional estimates for the financial year released around the end of May or early June (5 June 2026 for 2025-26), later revised.
• A new series. On 27 February 2026 MOSPI released a new GDP series with base year 2022-23, replacing the 2011-12 series. Growth rates from the old and new series are not directly comparable.

Read the real GDP growth rate (after removing inflation) for the economy's pace, and nominal GDP growth (before removing inflation) as a rough guide to how fast company revenues can grow in aggregate. The release also shows Gross Value Added (GVA) by sector: agriculture, manufacturing, construction, financial services and others. GVA by sector is more useful to a share investor than the headline, because it shows which part of the economy is doing the work.

Two monthly releases fill the gaps between GDP reports:

• Index of Industrial Production (IIP): output of mining, manufacturing and electricity. Since April 2025, MOSPI releases it on the 28th of each month at 4:00 PM, about 28 days after the month ends. It also has a "use-based" breakdown (capital goods, consumer durables, infrastructure goods and so on), which maps neatly onto sectors.
• Periodic Labour Force Survey (PLFS) monthly bulletin: unemployment and labour force participation, released around the 15th of each month, with a fuller quarterly bulletin.

The 10-year government bond yield

The Government of India borrows by selling G-secs (government securities). The yield on the benchmark 10-year G-sec is the closest thing India has to a "safe" long-term return in rupees, and it is the number most often used as the risk-free rate in valuation.

Bond prices and yields move in opposite directions. When investors expect higher inflation or more government borrowing, they demand a higher yield, and existing bond prices fall. Yields respond to RBI decisions, the government's borrowing plans in the Union Budget, inflation, global yields and foreign demand for Indian bonds.

A simple comparison links bonds and shares. The Nifty 50's earnings yield is 1 / P/E. A P/E of 20 gives an earnings yield of 5%. If the 10-year G-sec yields more than that, you are accepting a lower current yield on shares in return for expected growth in earnings. When bond yields rise sharply while share prices do not fall, shares look more expensive relative to bonds. This is a rough lens, not a timing tool. Bonds, yields and Indian stocks covers it in depth.

Where to find the yield: Financial Benchmarks India Ltd (FBIL) publishes benchmark G-sec yields every working day, and the RBI's Database on Indian Economy carries historical series.

The rupee, crude oil and foreign money

The rupee. A weaker rupee (more rupees per US dollar) helps exporters such as IT services and some pharma and textile companies, and hurts importers such as oil marketers and companies with foreign-currency debt. It also pushes up imported inflation. FBIL publishes daily reference rates for the rupee against major currencies.

Crude oil. India imports most of the crude oil it uses, so higher oil prices widen the import bill, can weaken the rupee and push up inflation. They tend to hurt paints, tyres, airlines and oil marketing companies (whose input is crude) and can help upstream oil producers. The Petroleum Planning and Analysis Cell (PPAC) publishes import and price data.

Foreign portfolio investors (FPIs) own a large share of the biggest Indian companies, so their buying and selling can move the market for weeks at a time. FPI investment data has been published daily on the NSDL and CDSL websites since 1 June 2014, and SEBI's website carries the statistics. Domestic institutional investors (mutual funds, insurers, pension funds) increasingly offset FPI selling, helped by steady monthly SIP money. When you read "FPIs sold ₹X crore today", check whether domestic institutions bought.

The economy is not the stock market

Strong GDP growth does not guarantee strong share returns, for three reasons:

• Prices already contain expectations. If everyone expects 7% growth and the economy delivers 7%, there is no surprise to push prices up. If valuations were already high, good growth can come with flat share prices.
• Listed companies are not the whole economy. Much of India's output comes from farms, small businesses and unlisted firms. The Nifty 50 is weighted toward financial services, energy and IT, which do not mirror GDP.
• Markets look ahead. Share prices often bottom while the economic news is still bad, and peak while it still looks good.

So treat economic data as context for which sectors face a headwind or tailwind, not as a buy or sell signal for the index.

The Indian economic calendar

MOSPI publishes an advance release calendar for each financial year on its website with the exact dates, and the RBI lists upcoming MPC meetings. Put both in your phone calendar.

Try it

1. Go to the MOSPI website and open the latest CPI press release. Write down: the month it covers, the combined all-India inflation rate, food inflation (CFPI), and which division moved most. Is headline inflation inside the RBI's 2% to 6% band?
2. On the RBI website, open the latest MPC resolution. Write down the repo rate decision, the vote, the stance and the projected CPI inflation for the current year.
3. On the FBIL website, find the latest 10-year benchmark G-sec yield.
4. From the latest Nifty 50 factsheet on the NSE Indices website, take the P/E and calculate the earnings yield (1 / P/E). Compare it with the 10-year G-sec yield. Write the date next to every number.
5. Repeat steps 1 to 4 after the next CPI release and the next MPC meeting. Note how the Nifty Bank index moved on each day compared with the Nifty 50.
