Government Budget, Fiscal Policy, and Market Impact

On 20 September 2019 the government cut the base corporate tax rate for domestic companies from 30% to 22%. The Nifty closed up 5.32% that day, its best session in a decade. No order had been booked. No plant had been built. One policy line changed the after tax value of every listed company, and the market repriced all of it in six hours.

Now look at 1 February 2026. A Sunday, with NSE open for a special Budget session. The speech raised the securities transaction tax (STT) on futures from 0.02% to 0.05% and on options premium from 0.1% to 0.15%. The Nifty closed at 24,825.45, down 1.96%, its worst Budget day in six years. Two sessions later it was at 25,727.55, above where it started. Fiscal policy moves prices. The first reaction is rarely the last one. The gap between the headline and the arithmetic is what this page is about.

The Union Budget, what it contains

The Union Budget is presented on 1 February. It moved from the last working day of February in 2017 so that money could be allocated before the financial year starts on 1 April. The document that matters most for an investor is not the speech. It is the one page table in Budget at a Glance. Four blocks sit inside it:

• Revenue receipts: tax revenue (income tax, corporation tax, GST, customs, excise) and non tax revenue (dividends from public sector companies, the RBI surplus transfer). FY27 BE: ₹35.33 lakh crore, of which net tax to the Centre is ₹28.67 lakh crore.
• Capital receipts: borrowing, recovery of loans and other receipts such as stake sales. Borrowing and other liabilities for FY27 BE: ₹16.96 lakh crore. That number is the fiscal deficit.
• Revenue expenditure: salaries, pensions, subsidies, interest and scheme transfers. Recurring money that creates no asset on the government's books. FY27 BE: ₹41.25 lakh crore.
• Capital expenditure: roads, railways, defence equipment, ports, urban transit. Money that builds an asset. FY27 BE: ₹12.22 lakh crore, and ₹17.15 lakh crore if you add grants for creating capital assets (the "effective capex" line).

The Budget also publishes where each rupee comes from and where it goes. Read it once and the rest of the document makes sense.

Two numbers in that picture should stay with you. 24 paise of every rupee the Centre spends is borrowed. 20 paise goes to interest on what was borrowed before. That is the fiscal constraint in one line.

Fiscal deficit, the single most watched budget number

The fiscal deficit is total expenditure minus total receipts, excluding new borrowing. It is the government's borrowing requirement for the year, shown as a percentage of GDP. A larger deficit means more government bonds, and that has three effects an equity investor feels:

• Yields: more bond supply against the same demand pushes bond prices down and yields up.
• Crowding out: banks and insurers that buy government paper have less left for companies.
• RBI headroom: a loose budget adds to demand, and that makes the RBI's inflation job harder.

The path since the pandemic is the cleanest fiscal story India has told in two decades. The deficit was 9.2% of GDP in FY21. In 2021 the government committed to bring it below 4.5% by FY26. The revised estimate for FY26 came in at 4.4%. FY27 is budgeted at 4.3%.

From FY27 the anchor changes. The speech moved the target from the deficit to debt. Central government debt is estimated at 55.6% of GDP in FY27 against 56.1% in FY26, and the goal is 50% (plus or minus 1) by 2030 to 31. The deficit is now the tool used to reach the debt goal. In practice that means smaller annual cuts in the deficit from here, so do not expect a falling deficit to keep pulling bond yields down the way it did from 2021 to 2025.

Budget themes that move markets

Every Budget has four or five themes that change the earnings or the cost base of a sector. Map each line in the speech to the sector it touches, then check whether the change is big enough to show up in profits.

Worked example, reading Budget 2026 in rupees

Take the FY27 Budget at a Glance table and do four divisions. It takes ten minutes and tells you more than a day of commentary.

1. Capex share of spending: ₹12,21,821 crore of capex divided by ₹53,47,315 crore of total spending is 22.8%. In FY25 actuals it was ₹10,51,953 crore out of ₹46,52,867 crore, or 22.6%. The share is steady. The government is not shifting the mix further towards capex this year. It is holding it.
2. Capex growth: ₹12.22 lakh crore against the FY26 revised ₹10.96 lakh crore is 11.5% growth. Against the FY26 budget figure of ₹11.21 lakh crore it is 9%. FY26 underspent its own target by about ₹25,000 crore. That gap is a signal on its own.
3. Interest burden: interest of ₹14,03,972 crore against net tax revenue of ₹28,66,922 crore is 49%. Half of what the Centre keeps in tax goes to service old debt. This is why the debt anchor exists.
4. Capex as a share of GDP: ₹12.22 lakh crore against assumed nominal GDP of ₹393 lakh crore is 3.1%.

Now the price action. Defence stocks had run up before the speech, the exchanges and brokers that earn from F&O volume took the STT hit, and the index recovered within two sessions.

The pattern to remember: the run up happens before the speech, the overreaction happens on the day, and the fundamental effect shows up over the next four quarters.

The Economic Survey, the document before the document

Shortly before the Budget, the Finance Ministry publishes the Economic Survey, written by the office of the Chief Economic Adviser. It is the government's own diagnosis: what worked, what did not, where growth is coming from and what worries them.

The Survey often signals priorities. If it spends three chapters on rural distress, expect a rural budget. If it spends them on logistics costs, expect capex and freight. A simple discipline: read the Survey's overview chapter the evening before the Budget and write down three sectors you expect to be touched. The next day, check how many you got right. It keeps your expectations honest.

Post budget, when the real signals arrive

Do not trade the speech. It is partly priced before it is read, and the first reaction is often reversed, as February 2026 showed. Track the lag signals instead:

• Monthly, from the Controller General of Accounts (CGA): at the end of every month the Centre's accounts for the previous month come out. Capex spent against the budget tells you whether the promise is being kept. For April to August 2026 the fiscal deficit was ₹7.10 lakh crore, 41.9% of the full year target, against 38.1% a year earlier. Capex was about 42% of the year's target, ahead of last year's pace.
• 6 to 12 months out: order books of capital goods, construction and defence companies start to show the tenders, and that reaches quarterly earnings.
• The sequence: announcement, sector rally on the news, order book growth in the second and third quarters, earnings growth, and then a second rerating if the earnings arrive.

7. Next 1 FebruaryRevised estimates

   What was really spent. FY26 capex was revised from ₹11.21 to ₹10.96 lakh crore.

Borrowing programme, the most underrated budget number

The headline is the deficit ratio. The number bond traders care about more is gross market borrowing: how much new government paper will be auctioned in the year. For FY27 it is ₹17.2 lakh crore gross and ₹11.7 lakh crore net of repayments, through dated securities. The rest of the deficit is funded from small savings and other sources.

If the Centre needs to borrow more, it has to clear the market at a higher yield, especially when foreign demand is weak and the RBI is not buying bonds. Higher government yields lift the whole rate stack. Corporate bonds reprice. NBFC funding costs rise. The discount rate in every equity valuation moves up a notch. By early October 2026, with the RBI raising the repo rate to 5.50% and Brent crude above $100, the 10 year government bond yield had moved above 7%, its highest in about two years.

Just before each half year begins, the RBI and the government publish the borrowing calendar: the week by week auction schedule. Auctions that clear with strong bids mean supply is being absorbed easily. Weak bids, or bonds devolving on primary dealers, mean stress. Equity investors who ignore the auction calendar miss the earliest read on liquidity.

Disinvestment, the elastic line in the budget

Stake sales in public sector companies sit in the line called "other receipts", along with asset monetisation. It is announced with confidence and realised with difficulty. For FY26 the Budget assumed ₹47,000 crore. The revised estimate cut it to ₹33,837 crore, a 28% shortfall. FY27 assumes ₹80,000 crore.

Two signals come out of this line. First, the companies named for stake sales often see speculative buying after the Budget, and selling pressure when the offer for sale actually arrives. Second, the gap between the target and the run rate tells you about borrowing pressure later in the year. If the first half misses badly, the shortfall has to be covered somewhere, by more borrowing or by cutting capex. Watch the receipts against the budgeted run rate. The variance is the signal.

State budgets, the half of fiscal policy that gets ignored

The Union Budget gets the headlines. The 28 states and the union territories with legislatures present their own budgets in February and March, and together they spend more on capital works than most investors assume. In FY27 the Centre also plans to transfer ₹25.44 lakh crore to states through tax devolution, grants, loans and scheme releases.

The data is scattered but public. Each state publishes its budget documents. The RBI's annual study of state finances aggregates them with a lag. Two patterns are worth knowing. State capex has tended to bunch up before state elections and slow after them. And states often spend a large share of their capex budget in the last quarter of the year. A cement or construction company with most of its business in two or three states is more exposed to those state budgets than to the Union Budget.
