Iran-US War:  — Market Impact Analysis Across Three War Scenarios

The Iran-US conflict presents a classic geopolitical oil shock with material but manageable implications for Indian equities. This view is based on 50 years of war-crude oil patterns, taken  with India’s current energy use profile and sector exposures. While near-term volatility is inevitable, the medium-term impact will be highly differentiated by sector and business quality.

Key Conclusions

Our analysis points to four core findings. 

• First, oil prices systematically overreact to war headlines, then normalize within 6-9 months as supply routes adjust. 
• Second, India’s 89% oil import dependence and 50% Strait of Hormuz exposure for its oil imports createvulnerability on a spike in the import bill, but domestic economic strength and government policy buffers provide meaningful cushion. 
• Third, market corrections in past geopolitical events ranged from 8-20% depending on conflict duration and oil trajectory. 
• Finally, quality businesses with pricing power, global revenues, and minimal energy intensity have consistently outperformed during and after oil shocks.

Understanding Historical Oil-War Patterns

Research from Equirus Securities analyzing five decades of conflicts reveals the following data:

The data suggests that markets embed a large geopolitical risk premium even when physical supply losses are minimal or temporary. But in recent years, the duration of spike has significantly come down. 

The Russia-Ukraine precedent is instructive. When Russia invaded Ukraine in early 2022, markets initially assumed prolonged conflict would keep crude structurally above $100/barrel and push oil marketing companies to distress valuations. Instead, after briefly spiking above $120, prices retraced as Russian barrels were rerouted — primarily to India and China — and market fundamentals reasserted themselves within six months.

India’s Current Oil Vulnerability Profile

India enters this crisis with high oil import dependence. 

• The country imports 88.5% of its crude requirements (first 10 months of FY26), amounting to 4.2 million barrels per day. 
• Critically, 50% of these imports transit through the Strait of Hormuz from Gulf suppliers — Saudi Arabia, Iraq, Kuwait, and UAE — making this a key transmission channel for any conflict escalation. 
• Direct Iran exposure, however, is negligible at just $113 million of oil imports in April-December 2025.
• On the cost side, every $10/barrel increase in crude adds approximately $13-14 billion to India’s annual import bill.

However, it is important to take note that India’s structural sensitivity to oil shocks has declined materially over the past decade. A recent analysis from HDFC AMC highlights three critical trends reducing India’s macro vulnerability, a fact that is often underappreciated. Oil imports as a percentage of GDP have fallen from 8.5% to 4.8%, meaning India’s economy has grown faster than its oil import bill, effectively halving the fiscal and current account impact of any given crude price increase. The petroleum share of total imports has also declined as India’s import basket has diversified into electronics, capital goods, and chemicals. Additionally, renewable energy investments have risen from 23% to 40% of power capacity, structurally reducing the economy’s long-term oil intensity. This declining oil beta means India is materially better positioned to absorb crude shocks today, than in past cycles such as 2008 and 2011-13.

Balance of Payments Risk if Oil Remains Elevated

While structural sensitivity has declined, sustained oil prices above $90 for 12+ months would still pressure India’s external account.  India’s current account balance is currently in pretty good shape. While a balance of payments crisis is unlikely, the CAD can certainly widen on a spike in the oil import bill, even as the services picture gets clouded by AI disruption.  

The Indian Rupee is just stabilising after a long spell of FPI outflows. Given that India (and China) are large net global oil consumers, this war will likely lead to knee-jerk FPI selling and reverse the trend of tentative FPI buying we have seen in February 2026. If it persists, this can set off a new bout of Rupee weakness. FX reserves, while strong at $725+ billion, could see drawdown if the RBI intervenes to manage currency volatility over 12-18 months.

This said, the impact of an oil price spike on the domestic economy and inflation are unlikely to be severe. The Indian government via oil marketing companies, has far absorbed much of the gains from soft oil prices without pass-through to businesses and consumers. It is therefore unlikely that the spike will now be fully passed on to end-users. The risk of a sharp spike in inflation from the oil shock, is cushioned by abnormally low inflation prints in recent times. Therefore, the risk of oil prices spiking inflation prints sufficiently to spook RBI into expedient rate hikes, is small.  

Yes, if the government absorbs fuel price increases through subsidies, the burden shifts to the fiscal deficit.

Given the above oil-war patterns and India’s oil vulnerability risk profile, we have tried to build 3 scenarios for the present war situation and their impact on oil price and the Indian stock market. 

Scenario 1: Short Conflict with Quick De-escalation (Base Case — 50% Probability)

This scenario assumes the conflict escalates for a few weeks with targeted strikes but without a structural blockade of the Strait of Hormuz. Diplomatic pressure from major powers — the US, China, and Europe — forces a ceasefire, with no broader regional involvement.

Oil Price Path

Brent spikes into the high-70s to low-80s range, representing a 10-15% increase driven by headline geopolitical premium rather than actual supply loss. The hike fades over 3-6 months as military risks recede, with prices drifting back toward a $65-70 baseline as fundamentals reassert.

Market Impact — Indian Equities

An index drawdown of 5-10% from recent highs is consistent with past Middle East risk events and India-Pakistan border tensions, which saw ~15% corrections that reversed within months. Recovery may happen at 2-6 weeks from the point the market senses de-escalation. Until then, sector leadership rotates toward more immune areas — banking and finance, domestic consumption including auto, healthcare, and defence. Foreign portfolio investors may slow flows but are unlikely to sell in panic, and the rupee weakens modestly but remains stable given strong FX reserves.

Investment Strategy

For investors with 3-5 year horizons, this scenario favours staying invested and using volatility to accumulate quality companies. Any 5-10% correction in structurally sound businesses with minimal oil sensitivity represents an attractive entry or accumulation opportunity. The key is to distinguish between temporary mark-to-market volatility and permanent earnings impairment.

Scenario 2: Longer War, Regionally Contained (35% Probability)

This scenario assumes the conflict extends for 6-18 months with the stated objective of degrading Iran’s nuclear and military infrastructure. Iran’s oil production or exports are partially disrupted (~1-2 million barrels per day). The Strait of Hormuz remains open but with intermittent threats and longer shipping routes. No direct involvement from Russia or China, though diplomatic support for Iran continues.

Oil Price Path

Brent settles in the $80-95 range steadily over 6-18 months. OPEC+ gradually increases production but takes time to offset the loss. The risk premium remains elevated due to persistent Hormuz uncertainty.

Market Impact — Indian Equities

An index drawdown of 10-20% from recent highs is possible, unfolding in multiple legs rather than a single panic selloff, with a recovery timeline of 9-15 months depending on the oil peak and policy response. The current account deficit widens from ~1% currently, and the rupee depreciates. Inflation pressures force the RBI to restart a rate hiking cycle,  FPIs turn persistent net sellers, and earnings downgrades concentrate in cyclicals, discretionary consumption, and energy-intensive sectors.

Investment Strategy

The defining characteristic of this scenario will be material sector differentiation. 

• Quality businesses with pricing power, minimal energy intensity, and global revenue linkages significantly outperform, making proactive portfolio rebalancing toward immunity and quality essential.
• Our approach would be to increase exposure to structural immunity sectors — banking and finance, select consumer segments, defence, and healthcare — in tranches as the market corrects, building defensive positions at 10-15% corrections.
•  Vulnerable sectors should be reduced or avoided until visibility on the oil peak and demand resilience improves.
• Small-cap cyclicals lacking balance sheet strength are best avoided, as they can be hit hard in broad market corrections. Staggered deployment is preferable to trying to catch the bottom.

The historical precedent from the 2022 Russia-Ukraine conflict is relevant: investors who used the March 2022 correction — when the Nifty fell ~18% from peak — to add quality IT, pharma, and financials generated strong returns over the subsequent months as oil normalized and these sectors demonstrated earnings resilience.

Scenario 3: Iran Backed by Major Powers (Stress Case – 10-12% Probability)

This scenario assumes Iran receives overt military or strategic backing from Russia and/or China, with risk of sanctions spillover affecting broader energy trade. A credible threat to the Strait of Hormuz — through mining, missile attacks, or naval confrontation — emerges, with potential for the conflict to trigger wider regional instability or great-power confrontation.

Oil Price Path

Markets price not just temporary Iranian supply loss but a structural risk premium on all Middle East flows. Brent can move into the $95-110+ range if the Strait of Hormuz is perceived as unsafe. Duration is uncertain, depending on diplomatic resolution or military outcomes, with potential for demand destruction at these price levels to eventually cap upside.

Market Impact — Indian Equities

An index drawdown of 15-20%+ from recent highs is likely, potentially approaching crisis-level corrections, with multiple compression across the board as growth expectations reset and a recovery timeline of 12-24 months depending on conflict resolution and oil normalization. The current account deficit widens, testing external stability. Inflation accelerates, forcing aggressive monetary tightening, and the rupee depreciates by closer to 10%. FPIs turn heavy net sellers, and there is a risk of rating agency outlook changes if macro stability is threatened. Domestic institutional flows and retail SIPs provide a partial offset but may be insufficient to prevent drawdown — and retail investors may themselves lose confidence and pause SIPs.

Investment Strategy

This scenario cannot be modeled with standard market forecasts given the number of extraneous factors in play. What is clear is that it requires maximum discipline and focus on capital preservation. The approach shifts decisively toward a defensive barbell: 

• Aggressively accumulate the highest-quality defensive franchises as they de-rate, while treating cyclicals and vulnerable sectors as options to be added very late once crude convincingly peaks and begins a sustained decline.
•  Holding on to a 15-20% cash allocation to capitalize on forced selling, deployed in stages only when quality franchises reach historically cheap valuations. 
• The focus will remain on businesses that will emerge stronger post-crisis.

Historical precedent from the global financial crisis (2008), taper tantrum (2013), and COVID crash (2020) shows that Indian equities have recovered from even 30-40% drawdowns within 12-24 months, with quality franchises leading the recovery.

Overall, while the Iran war does pose direct risks to India’s macros and markets, the risk is muted by the fact that India is currently sitting on :

• Strong government finances with low fiscal deficit
• Healthy current account with under 2% deficit
• Record high forex reserves of over $725 billion that amply cover imports
• Record-low levels of FPI ownership in the stock market with EM funds being underweight on India  

Our Prime Velocity/Vision portfolios are deliberately (and part fortunately 😊) built to handle the above scenarios. If you are our PMS subscriber, you will be receiving another note on how our portfolio is currently positioned to handle this. 

Well before the current conflict emerged as a mainstream concern, our portfolio construction was oriented around sectors structurally immune to crude price spikes and direct geopolitical disruption. Over two-thirds of our holdings sit in businesses — across banking and financial services, domestic consumption, healthcare, and defence — that are either insulated from or stand to benefit in a risk-off, oil-shock environment. We track these dynamics continuously, and our positioning reflects that vigilance.
