Fiscal stimulus

Topic: Government Budget, Fiscal Policy and FRBM · NCERT: Beyond NCERT

Meaning

A fiscal stimulus is a deliberate increase in government spending, or a cut in taxes, made to raise aggregate demand (AD) (the total spending on goods and services in the economy) during a slowdown or recession.

• It matters because it is the government's main tool to stop a slump from getting deeper, with lost jobs and lost incomes.
• It also has costs. It raises the deficit and the debt, so how big it can be depends on fiscal space.

Formula (spending effect, with a proportional income tax): Change in income (ΔY) = ΔG × 1 / [1 − c(1 − t)], where c = MPC (marginal propensity to consume) and t = tax rate.

Explanation

How it works

• Chain of effects:
• The government spends more (G ↑) or cuts taxes (T ↓).
• Households and firms get more income, so they spend more.
• That spending becomes someone else's income, and this repeats in rounds.

• This is the multiplier (the final rise in income is a multiple of the first push).

• Worked example (spending): c = 0.8, t = 0.25.

• Multiplier = 1 / [1 − 0.8 × 0.75] = 1 / 0.4 = 2.5.

• The government spends an extra ₹100 crore, so income rises by about ₹250 crore.

• Worked example (tax cut): with the same c and t, a lump-sum tax cut of ₹100 crore is multiplied by c / [1 − c(1 − t)] = 0.8 / 0.4 = 2.

• So income rises by about ₹200 crore.

• This is smaller than the spending effect because people save part of a tax cut before any spending starts.

• The NCERT offsetting idea: if investment falls by ₹50,000 crore, G must rise by exactly ₹50,000 crore. Total autonomous spending then stays the same, so equilibrium income does not change.

Types of stimulus

• Spending side:
• Capital expenditure (capex) (spending on roads, railways and other assets). It has a higher multiplier and adds to future capacity. It supports demand now and supply later.

• Revenue expenditure (salaries, subsidies, transfers). It is quick to deliver, but it builds no assets.

• Tax side: cuts in income tax or indirect taxes (for example excise and service tax). These leave people with more money to spend.

• Headline package vs real stimulus:
• Loans, credit guarantees (the government promises to repay a bank if a borrower defaults) and liquidity (money made available through banks and the RBI) look large in headlines.
• Only the part that adds to the deficit is a direct push to demand.

What limits it

• Three lags:
• Recognition lag: it takes time to see that a slowdown has started.
• Decision lag: Parliament must approve spending (the Art. 112–114 process).

• Implementation lag: projects take time to start. By then the cycle may already have turned, and the stimulus lands in a boom.

• Fiscal space: high debt and interest payments leave little room to act.

• Sovereign rating risk: a reckless stimulus can lead to a rating downgrade, then higher borrowing costs, then a bigger interest bill.
• Leakage through taxes and saving: a higher t or a lower c makes the multiplier smaller.

In India

• Legal frame: every stimulus shows up in the Union Budget, the Annual Financial Statement laid before Parliament under Art. 112. It is checked against the FRBM Act 2003 deficit limits.
• Escape clause: FRBM targets can be paused in a crisis. This was done in 2008-09 and in 2020.
• 2008-09 (Global Financial Crisis):
• Cuts in excise duty and service tax.
• FRBM targets were paused.

• The fiscal deficit rose to about 6% of GDP.

• 2020 (COVID-19), Atmanirbhar Bharat:

• The headline figure was about ₹20 lakh crore.
• Most of it was credit guarantees and liquidity, so the direct fiscal cost was much smaller.

• The recovery that followed was capex-led.

• The capex push continues (BE 2026-27):

• Union capital expenditure is ₹12,21,821 crore, which is 11.5% higher than RE 2025-26. Revenue expenditure grows only 6.6% [1].
• Public capex is set to rise from ₹11.2 lakh crore to ₹12.2 lakh crore in 2026-27 [1].

• ₹1,85,000 crore in special capex loans to states is budgeted for 2026-27 [1].

• Tax-side relief:

• The income-tax rebate threshold was raised to ₹12 lakh under the new regime in 2025-26.

• The government expected to give up about ₹1 lakh crore in revenue [1].

• How much room is left (BE 2026-27):

• Central debt is 55.6% of GDP. The target is 50 ± 1% by March 2031 [1][5].
• Interest payments are ₹14,03,972 crore. That is 40% of revenue receipts and 26% of total expenditure [1].

• 65.3% of revenue receipts go on committed expenditure (salaries, pensions and interest) [1].

• Fiscal deficit path (Union, % of GDP): 4.8% (2024-25 Actual), then 4.4% (2025-26 RE), then 4.3% (2026-27 BE) [1].

Don't confuse with

• Automatic stabilisers: proportional income tax and welfare transfers support demand in a slump without any decision. A fiscal stimulus is discretionary, meaning it needs a deliberate choice through the Budget or a package.
• A rising fiscal deficit: in a recession the deficit grows on its own, because tax revenue falls and transfers rise. That is not a stimulus. Only a rise in the structural (cyclically adjusted) deficit shows a truly looser stance.
• Monetary stimulus: this is done by the RBI through rate cuts and liquidity. Fiscal stimulus is done by the government through G and T.
• Austerity: this is the opposite. It means deep spending cuts and tax rises to reduce deficits. Done in a slump, as in Greece after 2010, it deepened the recessions.

Prelims Hooks

• Fiscal stimulus is a discretionary tool (a rise in G or a cut in T). A proportional income tax is an automatic stabiliser, not a stimulus.
• The multiplier with a proportional tax is 1 / [1 − c(1 − t)]. With c = 0.8 and t = 0.25 it equals 2.5, compared with 5 without the tax.
• Trap: "Atmanirbhar Bharat was a ₹20 lakh crore fiscal stimulus." This is wrong. It was mostly credit guarantees and liquidity, and its direct fiscal cost was much smaller.
• 2008-09: excise and service-tax cuts, FRBM targets paused, fiscal deficit about 6% of GDP.
• BE 2026-27: Union capex is ₹12,21,821 crore (+11.5%), against revenue expenditure growth of +6.6% [1].
• Economic Survey 2020-21 asked for a more active, countercyclical fiscal policy. It argued that growth leads to debt sustainability, and not the other way round [3].

Mains Points

• Quality over size: India's COVID response relied on guarantees and liquidity, plus a capex-led recovery. The capex share is still rising (+11.5% against +6.6% for revenue expenditure, BE 2026-27) [1].
• For: capex has higher multipliers, it crowds in private investment (draws private firms into investing), and it helped win the S&P upgrade to BBB in August 2025, the first since 2007 [2].

• Against: weak support for consumption hurt informal workers.

• Fiscal space and credibility:

• Interest takes 40% of revenue receipts, and committed spending takes 65.3% [1]. So the next stimulus must be targeted and temporary.

• Better ratings (S&P BBB [2]; R&I BBB+ in 2025 [6]) lower borrowing costs, which creates more fiscal space. A careless stimulus can reverse this chain.

• Rules vs flexibility:

• Rigid deficit rules can make policy procyclical, which makes the cycle bigger.
• An RBI study found that states' Fiscal Responsibility Legislations made their fiscal deficits move from procyclical to acyclical [4].
• India's shift to a debt glide path (50 ± 1% by 2030-31) [1][5], together with an escape clause, keeps room for countercyclical stimulus while keeping discipline.
