Iran War: $120 Oil Scenario Puts India FY27 Budget at Risk

Why policymakers are treating this as a multi-channel shock

India’s Finance Ministry has flagged that the current challenge is not a single macro shock but several arriving at the same time. The Iran conflict is pushing crude oil prices higher, worsening inflation pressures and straining the current account. A weakening rupee is amplifying imported inflation, making fuel and other commodities more expensive in local currency terms. The ministry has also pointed to weather risk, warning that a weak monsoon could push food prices up while also dampening demand. Together, these forces create a policy problem where growth support measures can clash with inflation, currency, and external-balance stability.

Officials have compared the potential disruption from the Iran war to the Covid-era shock, arguing the damage could linger beyond the immediate conflict period. Even with a ceasefire between Iran and the US, risks remain elevated because talks have not produced a resolution. Separately, US President Donald Trump told Axios he would keep Iran under a naval blockade until a deal addressing US concerns over Iran’s nuclear programme is reached, calling it “somewhat more effective than the bombing”. For India, the key transmission mechanism remains energy, especially any disruption risk around the Strait of Hormuz, a critical route for global oil trade.

What the Finance Ministry is stress-testing

Government officials said the ministry has mapped multiple scenarios, including one where crude averages $120 a barrel for the full year. While the government is sticking to its forecast of 6.8% to 7.2% growth for the fiscal year through March 2027, several economists have started trimming projections. Goldman Sachs has projected 5.9% for 2026, while Oxford Economics expects 6.2%.

One internal assessment cited by officials said the situation has the potential to reduce India’s FY27 growth by 0.3 to 4 percentage points, though officials cautioned that it is difficult to judge a full-year impact based on roughly 45 days of disruption. Officials also said that if average oil prices stay around $10 to $10 this year, they see “nothing to worry”. But if the conflict continues for three to four months or more, some pass-through to retail fuel prices may need consideration.

Fiscal deficit target, slippage risks, and why fuel matters

For FY27, the government has targeted a fiscal deficit of 4.3% of GDP. Economists, including Standard Chartered’s Anubhuti Sahay, have argued the deficit could widen by 0.7 to 0.9 percentage point, taking it to above 5% of GDP, if higher oil prices are absorbed through the budget.

So far, officials say the government has used tax cuts and limited price increases to cushion consumers. But they acknowledge the cushion may narrow if crude stays elevated and supply disruptions persist. One economist at DBS, Radhika Rao, said that if the supply shock deepens, a gradual increase in retail fuel prices could be the next step, potentially causing some demand destruction similar to what was seen in 2022 after Russia’s invasion of Ukraine.

Taxes under pressure as targets get reassessed

Government sources told CNBC-TV18 that FY27 tax arithmetic is “coming under stress” and that both direct and indirect tax collections could take a hit amid the West Asia crisis. The Budget had pegged gross tax revenue at ₹4,404,000 crore for FY27, including ₹2,697,000 crore from direct taxes and ₹1,700,000 crore (rounded from ₹1,679,000 crore) from indirect taxes, assuming 8% growth.

A separate update from government sources said direct tax collections for FY26 fell short of the revised estimate of ₹2,421,000 crore by over ₹10,000 crore, mainly due to weaker-than-expected income tax inflows. While the gap is small relative to the overall base, officials see it as an early sign that tax buoyancy may not track assumptions if growth, profits, or employment cool.

Subsidies, excise cuts, and the cost of cushioning consumers

On the spending side, the government is likely to face higher outgo on fertilisers and petroleum subsidies, budgeted at ₹183,000 crore for FY27, as global commodity prices rise. At the same time, revenue is being hit by fuel excise adjustments. A report citing the Central Board of Indirect Taxes and Customs (CBIC) said a recent excise duty cut of ₹10 per litre on petrol and diesel resulted in an estimated ₹7,000 crore revenue loss in just 15 days, with the full-year impact expected to exceed ₹100,000 crore.

Another estimate discussed in a market commentary suggested the government could be giving up about ₹7,000 crore every fortnight, which would imply an annual hit of roughly ₹180,000 crore, described as around 0.5% of GDP. These figures highlight why officials are watching the duration of the shock closely, especially if the Strait of Hormuz remains constrained and oil stays high.

Capital spending remains the stated priority

Despite the uncertainty, government sources said India sees no immediate risks to the fiscal deficit target for the year that began April 1 and will continue to prioritise capital spending. Officials are considering austerity measures including spending curbs in ministries with limited capacity to use allocated funds, but they want to continue spending on roads, railways, and airports.

The Union Budget put FY27 federal capital expenditure at ₹1,222,000 crore, up from revised spending of ₹1,096,000 crore in FY26. Officials also noted that budget projections may change due to the crisis, but the exact impact would likely become clearer in the second half of the year once there is more data.

External account risks: oil imports, remittances, and rupee pressures

The ministry has warned that if supply disruptions persist, consequences could extend beyond inflation into fiscal and external imbalances. It also flagged the possibility that remittance flows could weaken if labour markets in the Gulf deteriorate, creating a second-order risk where external income declines even as import costs rise.

Foreign investors are already wary. Overseas funds have pulled nearly $19 billion from local markets in the first few months of the year, close to the full-year record for 2025, according to the report. Separately, an Oxford Economics economist, Alexandra Hermann, said multiple channels are under strain at once, including the rupee, household purchasing power, Gulf remittances, fiscal space and private investment, calling the vulnerability “unusually broad-based”.

Trade deficit snapshot amid oil volatility

A trade update cited in the material said the March goods plus services deficit narrowed year-on-year to $1.44 billion from $1.5 billion, helped by a lower oil deficit. But it also noted the deficit was lower because both imports and exports fell in March, with imports falling more than exports. The same note added that the FY26 goods plus services deficit was 26% higher, and that FY27 started on a weaker footing.

Key numbers to track

Market impact: what changes for investors and households

The immediate market sensitivity remains oil, because higher crude transmits into inflation, the current account, and fiscal arithmetic. If the government continues to absorb fuel costs through excise reductions and subsidies, the fiscal deficit may face pressure even before any growth downgrade feeds into tax collections. If the government allows more pass-through to pump prices, household purchasing power can come under stress, with potential implications for consumption-sensitive sectors.

On external balances, the combination of a higher energy import bill and the risk of weaker Gulf remittances increases uncertainty around the rupee and India’s financing needs. Officials have also indicated that budget assumptions will not be revised immediately, and one source said projections would typically be reconsidered only if the situation persists for at least two to three months.

Why the policy dilemma is becoming sharper

The Finance Ministry’s review highlights a dilemma visible across governments globally: short-term growth support can destabilise inflation, currency, and external balances if shocks persist. In India’s case, the tension is amplified because fuel taxes are a meaningful revenue source and because the government is trying to protect capex plans while keeping retail fuel prices stable.

Economists quoted in the material described the shock as cyclical for now, but noted that if high energy costs, subsidy pressures, and delayed private capex persist, cyclical damage could start bleeding into potential growth. That framing matters for investors because it shifts the debate from a temporary oil spike to longer-lasting effects on investment and fiscal credibility.

Conclusion

India’s official stance remains that near-term growth and fiscal targets are manageable, but the Iran conflict has introduced a high-stakes variable into oil prices, inflation, taxes, and subsidy costs. The government is stress-testing scenarios such as $120 crude, reviewing tax assumptions, and weighing how long it can keep absorbing the shock without retail price pass-through. The next key data point on the domestic cycle is the release of fourth-quarter GDP and provisional full-year figures on 28 May, while officials have indicated a clearer fiscal read-through may only emerge in the second half of the year.
