This is the question confusing every serious market watcher in India right now. And it is worth asking carefully because the answer tells you something important about where Indian markets are headed.
The Indian Crude Basket, the official benchmark that reflects what Indian refineries actually pay for imported oil, hit a record 146.39 dollars per barrel on March 18, 2026. That is not a rounding error. That is not a one day blip. The basket averaged 63 dollars per barrel in January 2026. It averaged over 110 to 114 dollars per barrel through March so far. In less than seven weeks, the effective cost of India’s single most important import has more than doubled.
And the 10 year Indian Government Securities yield? It is sitting at 6.73 percent. Flat. Unmoved. Glued in a band of 6.70 to 6.75 percent for weeks. As if nothing happened.
That divergence, between crude exploding and bonds doing absolutely nothing, is what a senior market analyst recently called a 20 marks question. Here is the full answer.
What is Indian Crude Basket Actually?
The Indian Crude Basket is not Brent. It is not WTI. It is a specific weighted average calculated daily by the Petroleum Planning and Analysis Cell, PPAC, under India’s Ministry of Petroleum and Natural Gas, designed to reflect what Indian refineries are actually paying for the crude they process.
The composition as of 2026 is approximately 78.71 percent sour grade crude, a weighted average of Dubai and Oman benchmarks, which are the grades that dominate Middle East supply, and 21.29 percent sweet grade crude tracked against Brent Dated. That roughly 79 to 21 sour to sweet split has stayed broadly stable for years because India’s refinery configuration is built around processing heavier, more sulfurous Middle Eastern crude.
What this means in practice is that the Indian Crude Basket is more sensitive to Middle East supply disruptions than headline Brent futures. When the Strait of Hormuz is disrupted, when Iranian strikes hit Gulf energy infrastructure, when the Dubai and Oman benchmarks spike on supply uncertainty, the Indian Crude Basket moves faster and further than the global headline numbers suggest. It did exactly that through March 2026, climbing from 63 dollars in January to 146.39 dollars on March 18, a move of more than 130 percent in seven weeks.
That is the most dramatic single sustained rise in the basket’s history.
So Why Are Bond Yields Not Reacting
Here is the answer, in full, in order of importance.
Reason One, The Market Thinks This Is Temporary
The most important reason bond yields have not moved is the simplest one. The bond market does not believe the oil spike is permanent.
Bond yields, particularly the 10 year yield which anchors long term borrowing costs across the entire economy, are not priced off today’s crude price. They are priced off expectations of inflation and interest rates over the next decade. And right now, the dominant market view is that the West Asia conflict is a short duration event. Traders are pricing in de escalation, diplomacy, or supply normalisation that brings crude back toward the 80 to 100 dollar range within weeks.
Nobody in the bond market is pricing in sustained 120 to 150 dollar oil through 2026 and 2027. If that view is correct, the oil spike does not change the long run inflation and rate path enough to justify a meaningful yield move. Bonds are saying this too shall pass.
If they are wrong, if Phase 2 of the Iran conflict drags through April and into May with no de escalation, that calculus changes very quickly. Most analysts are watching for a sustained crude price above 110 to 120 dollars for four to six consecutive weeks as the trigger that would finally force the bond market to reprice. Until that threshold is crossed and held, yields stay anchored.
Reason Two, The RBI Is Actively Capping Yields
The second reason is not market consensus. It is central bank intervention. And it is happening at scale.
In March 2026, the Reserve Bank of India announced a one lakh crore rupee Open Market Operations programme, that is 100000 crore rupees of government bond purchases, split into two equal tranches of 50000 crore each. The first tranche settled on March 10. The second settled on March 16. The RBI stepped into the secondary market and bought government securities across multiple maturities, injecting liquidity and directly supporting bond prices, which means suppressing bond yields.
The first tranche alone involved purchases across seven securities, from the 6.01 percent GS 2030 to the 7.30 percent GS 2053, at cut off yields ranging from 6.27 to approximately 6.95 percent. The RBI accepted the full 50000 crore in both tranches.
The official stated purpose was to offset liquidity tightening from advance tax payments and GST collections in mid March, which typically drain two lakh crore rupees or more from the banking system. But the timing, in the middle of the most dramatic crude price surge in India’s recent history, was not coincidental. The RBI is prioritising yield stability. It is absorbing the selling pressure that oil fears would otherwise generate in the bond market. It is choosing to cap the yield rather than let market forces price in the oil shock.
This is a deliberate policy choice with a cost. The cost is that the bond market is being prevented from sending an honest signal about what a 146 dollar crude basket means for India’s fiscal and inflationary outlook. That signal will eventually arrive. The OMO programme delays it, it does not cancel it.
Reason Three, Oil Has Not Hit the Consumer Yet
The third reason yields have not moved is that the oil shock has not yet translated into the consumer price inflation that bond markets actually care about.
Petrol and diesel retail prices in India are unchanged. The government is holding the line, zero percent change in domestic fuel prices through the period when the crude basket doubled. Indian Oil, Bharat Petroleum, and Hindustan Petroleum are absorbing the difference between what crude costs and what consumers pay, the under recoveries that have historically been a major source of fiscal stress in India during oil price surges. The Finance Minister has publicly described the inflation impact as not substantial because headline Consumer Price Index data remains moderate.
Bond yields care about sustained CPI inflation and the RBI’s rate response to that inflation. If petrol prices are frozen, if CPI stays contained, and if the government signals it will absorb the shock rather than pass it through, the inflation channel that would normally transmit an oil price surge into higher bond yields is blocked. Temporarily. At significant fiscal cost. But blocked.
The moment that changes, the moment the government decides it cannot continue absorbing under recoveries at 146 dollars per barrel and raises petrol prices, the CPI channel opens. And when the CPI channel opens with the kind of oil price that is currently embedded in the crude basket, the bond market will move. Fast.
Reason Four, Russia Is Making the Real Number Lower Than the Headline
The fourth reason is technical but important.
The published Indian Crude Basket, the 146.39 dollars per barrel figure that is generating headlines, is a benchmark calculation based on Dubai, Oman, and Brent weightings. It reflects what Indian refineries would pay if they bought all their crude at Middle East spot prices.
They do not. Not even close.
Approximately 30 to 40 percent of India’s actual crude imports now come from Russia, purchased at significant discounts to the benchmarks that go into the basket calculation. Russian Urals crude, sold to India at discounts that have ranged from 20 to 35 dollars per barrel below Brent in recent periods, means India’s actual blended import cost is meaningfully lower than the published basket figure.
The bond market, staffed by sophisticated analysts who know how India’s oil import mix actually works, is partially discounting the 146 dollar headline number because it knows the real average cost is lower. This does not make the oil shock irrelevant, even discounted Russian crude has gotten more expensive as global benchmarks have risen. But it does explain why the bond market is not treating 146 dollars as the literal cost to the Indian economy that it appears to be on the surface.
Reason Five, Domestic Demand for G Secs Is Overwhelming Supply
The fifth reason is structural. India’s government bond market has a captive buyer base, banks required to maintain statutory liquidity ratios, insurance companies with long duration liability matching requirements, the Employee Provident Fund Organisation investing retirement savings, and provident funds across the public sector, that buys government securities in enormous quantities regardless of near term oil prices or geopolitical events.
This structural demand does not go away when crude spikes. It may actually increase in times of uncertainty as these institutions rotate toward the relative safety of sovereign paper. The March OMO auctions saw the EPFO and other long term institutional investors as active buyers, the same institutions that provide the RBI with a reliable partner in its yield management operations.
With the RBI buying on one side and captive institutional demand buying on the other, the supply of government bonds available to price sensitive market participants is limited. In a thin float market, forced institutional demand overwhelms whatever selling pressure oil fears generate. Yields stay anchored.
The Question Nobody Is Asking, What Happens When All Five Reasons Break Down Simultaneously
Each of the five reasons above is a delay mechanism, not a permanent fix. And they are all subject to the same underlying condition, that the West Asia conflict resolves relatively quickly and crude retreats toward pre war levels.
If Phase 2 of the Iran conflict extends beyond April, the market’s this is temporary consensus breaks down. The RBI cannot run OMO programmes indefinitely without stoking its own inflationary concerns. The government cannot absorb under recoveries at 146 dollars per barrel without fiscal slippage that eventually forces either a petrol price hike or a wider deficit, both of which are yield positive. Russia’s crude discount, while real, does not fully offset a 130 percent rise in the benchmark. And even captive institutional demand has limits if inflation expectations become unanchored.
Most market analysts are watching the 6.85 to 7.0 percent level on the 10 year G Sec as the first meaningful breakout target if the oil shock persists. At the current pace, with Phase 2 operations declared and Israeli officials signalling at least three more weeks of strikes, that breakout scenario is not a tail risk. It is a base case if de escalation does not materialise in the next two to three weeks.
What This Means for You
If you hold government bonds or bond funds in your portfolio, directly or through debt mutual funds, the current yield stability is a window, not a destination. The 10 year G Sec at 6.73 percent with crude at 146 dollars is a price that exists because of RBI intervention and market consensus about war duration. Both of those supports are conditional.
If the war extends, if crude stays above 110 dollars, if the government eventually passes through even a portion of the oil price increase to consumers, and if CPI starts moving meaningfully higher, the bond market will reprice. Yields will rise. Bond prices will fall. The timing is uncertain but the direction, in a sustained high oil scenario, is not.
The equity market has already partially priced in the oil shock through higher input cost fears for airlines, chemicals, logistics, and auto companies. The bond market has not. When it does, the repricing could be swift.
The crude basket at 146 dollars and the 10 year yield at 6.73 percent cannot coexist indefinitely. One of them is wrong about what comes next.
Right now, the bond market is betting the crude basket is wrong, that 146 dollars is a peak, not a floor, and that de escalation will bring it back toward levels the 6.73 percent yield can justify.
It may be right. But if it is wrong, you will want to have positioned for it before the bond market figures that out.
