Unfortunately our country has never solved the “oil” problem, it has only managed it better across successive cycles. Import dependency reached a new all-time high of 88.2% in FY25. The crude import bill was $137 billion before the current crisis, and the Hormuz closure of February 28, 2026 arrived not as a distant geopolitical risk but as an immediate supply disruption affecting roughly 55–60% of India's sourcing geography. Brent surged more than 60% (from $71 to $113) per barrel in under three weeks. The macro consequences are now moving through our system in a sequence that is largely predictable, but whose ultimate severity depends on one variable nobody can model with precision: how long the strait stays closed.
I am not attempting to write about that variable, but about the transmission chain. The specific mechanism by which a price on a barrel of oil in the Persian Gulf becomes a constraint on the RBI's monetary policy, a wider fiscal deficit, a depreciating rupee, and a higher discount rate on every equity growth story in the Nifty. This chain is both more textured and more empirically grounded than most coverage suggests.
The Interplay Between The 5 Channels
The standard framing of an oil shock, "costs rise, inflation follows, RBI tightens", is accurate but incomplete. It captures one channel and misses four others. The full transmission operates as follows, in the order it actually happens.
Imports: The import bill widens first. India imports approximately 4.84 million barrels per day. At that volume, every $10 per barrel increase adds $14–18 billion to the annual crude bill, derived from PPAC's FY25 import data. A $40 per barrel rise above the pre-shock $70 baseline implies $55–$70 billion in additional annual spending on oil, and this is before any demand adjustment.
The Exchange Rate: The exchange rate moves next, and faster than most anticipate. India must pay for that oil in US dollars. As the import bill widens, rupee sellers and dollar buyers accumulate in the foreign exchange market. The RBI can intervene, and has been, drawing down reserves from $728.49 billion on February 13 to $709.76 billion by March 13, a $18.7 billion drawdown in four weeks. Intervention definitely slows depreciation, it does not stop it. The rupee has already weakened past ₹93 per dollar as of this writing.
Inflation: Inflation follows, but with a structural filter. The empirical correlation between crude import prices and India's CPI over FY23–FY25 is approximately 0.30, a moderate relationship, not the tight mechanical link that commentary often implies. Three buffers absorb the shock before it reaches the consumer basket: administered fuel pricing, the food component's 45.9% weight in the CPI basket which can offset or mask fuel cost increases, and the managed exchange rate itself. The RBI's own pre-shock projection for CPI was 4.2% for FY27 Q3 and Q4. That was published in February 2026 before Hormuz. It is now effectively a floor, the actual outcome is almost certainly higher than 4.2% given what has happened since.
Fiscal Deficit: Spending goes up because the government has committed to keeping LPG and fertiliser affordable. When crude rises, the production cost for both of these rise up, and the government absorbs the difference automatically. The fertiliser subsidy alone costs an estimated ₹19,230 crore more than budgeted in FY26. Income comes down because the government faces pressure to cut the excise duty on petrol and diesel to protect consumers from the full price increase. Every ₹2 per litre cut in that tax costs approximately ₹32,000 crore in foregone annual revenue. The result is that the government ends up borrowing more than planned.
To do that, it issues more bonds. More bonds in the market push yields higher. Higher yields raise borrowing costs across the entire economy. This is how an oil price increase that starts at a refinery eventually raises the interest rate on a home loan or compresses the valuation of a company that has never touched a barrel of oil.
One more distinction is worth anchoring before moving to the data: this is a supply-driven shock, not a demand-driven one. When global demand lifts oil prices, India's IT export revenues, remittances, and manufactured goods exports tend to rise alongside, providing a partial buffer. A supply shock offers none of that. Costs rise while the global growth backdrop simultaneously deteriorates. The macro arithmetic is asymmetric in a way that matters.
The Arguments
The inflation baseline was not an actual cushion for the upcoming crisis.
CPI was at 1.33% in December 2025, historically low. This looks like a comfortable cushion as we head into a crisis. The data says it was not. Almost all of that low inflation came from one source: food prices falling sharply. This had nothing to do with monetary policy working well or any structural improvement in the economy. Because the fall in food prices was seasonal and weather-driven. It was always going to reverse.
And it was already reversing before the oil shock arrived. The RBI's own February 2026 projections, published before the Hormuz closure, already had Q1 FY27 inflation at 4.0% and Q2 FY27 at 4.2%, without any oil shock factored in. The inflation trajectory was heading upward on its own.
So the oil shock did not land on a stable, low-inflation foundation. It landed on one that was already shifting. When two things push inflation up at the same time, the spike is bigger than if they happened separately. That is the risk here, food prices are already rising back to normal levels, and oil costs are now rising on top of that. If both hit in the same quarter, the combined inflation reading will be sharper than either one would have caused alone.
The RBI cut rates, but the long end of the market did not cooperate.
Through 2025 the RBI cut its benchmark interest rate five times, bringing it from 6.50% to 5.25%. The expectation when a central bank cuts rates is simple, borrowing becomes cheaper across the board, for everyone.
That happened at the short end. But not at the long end.
The 10-year government bond yield initially fell alongside the rate cuts, reaching 6.22% by May 2025. Then it reversed and started climbing back up, hitting 6.77% by January 2026, even as the RBI was still cutting. The market was moving in the opposite direction to the central bank.
Why? Three reasons. The government was borrowing heavily, ₹14.82 lakh crore in FY26, hence pushing enormous bond supply into the market, which drove yields up. US bond yields were rising globally, pulling Indian yields higher through international spillover. And corporate borrowing had slowed, reducing demand for bonds at precisely the moment supply was increasing.
This divergence matters because the short end and the long end govern different things. The repo rate affects overnight bank borrowing. The 10-year yield affects home loans, corporate borrowing, and infrastructure financing. More importantly, it is the rate used to calculate what future corporate profits are worth today. When it rises, future earnings become less valuable in today's money, which is why equity valuations fall even in companies that have nothing to do with oil or energy.
The current account buffer is real but asymmetric.
India's current account deficit improved on paper in April–December 2025, narrowing from 1.3% to 1.0% of GDP. But the improvement came entirely from the services side. IT exports and remittances grew strongly. The goods side, where oil sits, was already moving in the wrong direction. The trade deficit in goods widened from $79.3 billion to $93.6 billion, partly because Indian refiners were already being forced to buy more expensive non-Russian crude under US sanctions pressure, before Hormuz added anything on top.
The thing holding it together is the services surplus. India's IT exports, GCC revenues, and remittances currently cover about 60% of the goods deficit. As long as that coverage stays above 55%, the CAD remains manageable even under moderate oil stress.
The risk is that this buffer is not guaranteed. IT and GCC revenues depend on US and European companies spending on technology. If a prolonged oil shock slows the global economy, those technology budgets get cut, and India's services surplus shrinks at precisely the moment it is most needed. The external position could weaken from two directions simultaneously: a higher oil import bill pushing the goods deficit wider, and a global slowdown compressing the services surplus that was covering it. This is the feedback loop that almost no standard oil-shock analysis for India accounts for.
The Russia discount is narrowing, independently of Hormuz.
India has been buying Russian oil at a $3–8 discount per barrel since April 2022, with Russian crude averaging $66.49/barrel over that period. That discount is shrinking due to US sanctions pressure. Indian refiners are already cutting Russian purchases, which is showing up in a wider trade deficit. If the discount narrows from $8 to $2–3 per barrel, India's oil bill rises by $7–9 billion annually on its 35.8% Russian crude exposure. Funnily it is on top of, not instead of, any risk from the Strait of Hormuz.
The Open Questions
These are the four most consequential things this analysis cannot tell you with confidence, and why each matters more than a standard caveat.
How food inflation and the oil shock will interact still remains an open question.
Food inflation and oil inflation may hit at the same time, and that timing matters. Vegetable prices have been unusually low, and as they normalize, they'll add 150–200 basis points to headline CPI through Q2 FY27 on their own. If this coincides with oil price pass-through in the same quarter, peak CPI could be high enough to force the RBI to hike rates. If they land in different quarters, the RBI may hold.
The MOSPI food price index (CFPI) is the key data series to track, it runs 4–6 weeks ahead of the CPI fuel component, making it an early signal for how these two pressures will interact.
Monetary policy transmission is asymmetric in a way the models miss.
India's bond yields closely follow US Treasury yields, hence the RBI doesn't fully control its own long-term rates. The gap between Indian and US 10-year yields fell to around 1.8% in May 2025, near a historic low. So if the US Fed keeps rates high due to its own inflation problems, Indian yields will rise too, regardless of what the RBI does. A brief dip in US yields around March 20 offered temporary relief, but it won't last if US inflation picks up.
The remittance channel has a considerable data lag.
India receives large remittances from Indians working in the Gulf, about 38% of the $36.9 billion received in Q3 FY26 came from the Middle East. If the Strait of Hormuz is closed for an extended period, Gulf economies slow down, refineries cut output, construction stalls, companies freeze hiring. This means Indian workers in the Gulf earn less or lose jobs, and send less money home. That's a hit to India's balance of payments that doesn't show up in any oil import calculation.
The bigger problem is timing. RBI data on remittances lags by about two quarters, so by the time the decline shows up in official numbers, 6–9 months of damage will have already built up. The only way to track this in real time is through tanker movement data and Gulf PMI surveys, neither of which is part of standard macro monitoring.
The political economy of pass-through sequencing cannot be modelled.
India has state elections running through FY27, and governments historically avoid raising fuel prices during election periods. So instead of passing the oil shock directly to consumers through price hikes, the government may absorb it by letting state-run oil companies (OMCs) take the loss. This definitely delays the inflation impact but damages government finances and the oil companies' balance sheets. The total economic damage doesn't shrink, it just hits later and falls on different institutions. Standard macro models assume a fixed relationship between oil prices and inflation, but they can't capture this delay. In practice, when the pain is passed through, and who absorbs it in the meantime, matters just as much as the size of the shock itself.
The Bottom Line
India has survived every oil shock since liberalisation. It will survive this one. But survival has always come at a cost, and this time, the bill is arriving from more directions at once.
The import bill is wider. The rupee is weaker. The fiscal cushion is thinner. The Russia discount is disappearing. The RBI is cutting while the bond market moves against it. These are not independent risks. They are compounding ones.
For investors, the instinct has always been to watch the prices at fuel pumps and wait. That instinct may turn out wrong this time. The real signals are upstream, CFPI food data, Gulf PMI, US Treasury yields, OMC quarterly results. These shall tell you where pressure is building before it shows up in headlines or earnings.
We believe that the sequence matters more than the magnitude. Food inflation and oil pass-through landing in the same quarter reprices rate expectations fast. That hits everything from growth stocks, to rate-sensitive sectors, mostly before most investors have adjusted.
