Indian Stock Market Remains Calm Despite Global Turmoil, FII Selling and Rupee Risks: What Is Keeping India VIX Low?
India's stock market is showing an unusual combination in 2026. Brent crude remains above $100 per barrel, the rupee has traded around Rs.96 to the dollar, global bond yields have surged, geopolitical risks remain elevated and foreign investors have withdrawn record amounts from Indian equities during the year. Yet India VIX, which measures the options market's expectation of Nifty volatility over the next 30 days, was only around 11.52.
Those buffers come at a cost. The RBI's extraordinary dollar mobilisation has created a large domestic liquidity surplus, forcing the central bank to sell bonds and potentially strengthening monetary-policy transmission. Domestic flows can cushion FII selling, but they cannot permanently shield corporate earnings from oil above $100. Low index volatility can therefore coexist with substantial risk at the sector and individual-stock level.
VIX is low, but the world is not calm
India VIX is derived from Nifty option prices and represents expected volatility over the next 30 calendar days. It measures the expected magnitude of market moves, not whether those moves will be up or down.
That distinction is especially important in 2026. Wright Research noted that India VIX traded at just 10.69 on August 20 after reaching 28.91 during the West Asia conflict. At the same time, its measure of geopolitical risk had risen to its highest level in roughly 25 years.
The contrast became even sharper in September. Brent moved above $100, the rupee weakened towards 96 per dollar, India's 10-year government bond yield moved above 7%, and the Nifty recorded five consecutive weekly declines by September 11. The index lost almost 4.8% over those five weeks, Yet India VIX was back around 12 on September 18.
The options market is therefore pricing something narrower than an absence of bad news. It is pricing an expectation that these shocks will remain manageable enough to avoid large, disorderly daily moves in the Nifty. The central question is what has kept geopolitical, currency and capital-flow stress from producing much higher index volatility.
Global conditions are becoming more difficult
There is little evidence that the international environment has become unusually benign. The IMF's July 2026 World Economic Outlook projects global growth of only 3.0% in 2026, compared with an average of 3.5% during 2024-25. Global headline inflation is expected to rise from 4.1% in 2025 to 4.7% in 2026, interrupting the disinflationary trend that had been underway since early 2024. World trade growth is also expected to slow from 5.0% in 2025 to 3.5% in 2026.
Energy has again become a major source of pressure. Brent was still around $103.5 per barrel even after declining for three consecutive sessions. Global central banks have consequently moved back towards tighter monetary conditions, with the Federal Reserve recently raising rates and bond yields repricing higher.
For India, high oil affects several variables at once. A larger import bill increases demand for dollars, putting pressure on the rupee. A weaker currency adds to imported inflation, which can push domestic rate expectations higher while also squeezing corporate margins.
Low India VIX should therefore not be read as evidence that the macro shock has disappeared. The more likely explanation is that India has developed stronger mechanisms for absorbing some of the pressure before it reaches the index.
India's economy is giving markets more room to absorb the shock
One source of resilience is the strength of domestic activity. Real GDP expanded 7.8% YoY in Q1 FY27, compared with 6.9% in Q1 FY26. Real GVA grew 8.2%, nominal GDP expanded 10.3%, and India's real GDP was estimated at Rs.81.36 lakh crore during the quarter.
An external shock is considerably more damaging to equities when it arrives alongside weakening domestic demand. That is not the current situation. Global conditions are deteriorating while domestic growth remains relatively strong, giving companies more room to absorb higher input costs through volumes, pricing or operating leverage.
GDP growth by itself, however, does not explain why VIX remains so low. A more significant change has taken place in who owns Indian equities and who holds India's dollars.
Domestic investors are replacing foreign investors at the margin
The change in India's equity ownership is probably the clearest explanation for why foreign selling now creates less index volatility than it once did. Cash-market exchange data show a striking pattern during January-August 2026.

July

March is the clearest example. Foreign institutions sold more than Rs.1.2 lakh crore while domestic institutions bought more than Rs.1.4 lakh crore. A decade ago, sufficiently large FII selling could produce a feedback loop in which falling prices pushed volatility higher, tighter foreign risk limits triggered more selling, and the decline fed on itself. Today, a much larger domestic pool of capital is available on the other side of that trade.
That does not stop markets from falling. It can, however, make the adjustment slower and less disorderly. Foreign flows themselves subsequently improved. Depository data showed roughly Rs.20,200 crore of FPI equity buying in July and around Rs.29,631 crore in August after four months of heavy selling. Even after that reversal, FPIs remained record net sellers for 2026 as a whole through August. Indian equities have therefore become less dependent on the daily appetite of the incremental foreign investor.
SIPs make the domestic bid more durable
DII buying would be less significant if the underlying money were highly cyclical. Mutual-fund data suggest that a meaningful part of it is not. AMFI reports the following monthly SIP contributions:
FY27
SIP contribution
April
Rs.31,115 cr
May
Rs.30,954 cr
June
Rs.31,781 cr
July
Rs.31,961 cr
August
Rs.32,297 cr
By August, SIP assets had reached approximately Rs.18.62 lakh crore, with more than 10 crore contributing SIP accounts. SIP money differs from discretionary institutional capital because it arrives according to household savings schedules rather than daily changes in geopolitical sentiment. That makes the flow particularly useful when foreign sentiment deteriorates. That kind of behaviour makes domestic flows a more dependable source of market liquidity during periods of stress.
RBI has built an extraordinary dollar buffer
A second buffer is operating outside the equity market. In June, the RBI introduced special USD-INR swap facilities for FCNR(B) deposits, external commercial borrowings and overseas foreign-currency borrowings. By August 31, the facilities had attracted $136.38 billion.

The impact on India's external balance sheet has been dramatic. Forex reserves reached a record $785.7 billion in the week ended September 4 after rising by roughly $120 billion over ten consecutive weeks.
Those reserves provide financial insurance against periods of intense dollar demand. If oil rises sharply, Indian importers need more dollars. Without a large reserve buffer, that demand can translate quickly into a weaker rupee, worsening inflation expectations, higher bond yields and an equity-market repricing.
A larger reserve position gives the RBI more capacity to supply dollars and make the currency adjustment more orderly. The resulting financial shock can reach equities more gradually.
Recent market behaviour is consistent with that mechanism. When the rupee briefly moved beyond Rs.96 per dollar on September 17, probable RBI intervention and portfolio inflows helped it recover to approximately Rs.95.93.
Why is India buying so many US Treasuries?
India's net purchases of US Treasuries rose from $3.39 billion in June to a record $15.2 billion in July. Moneycontrol reports that the increase followed the RBI's large dollar mobilisation programme.
The sequence matters more than the headline number. Foreign currency enters India through the swap programme, the RBI receives dollars, reserve assets increase, and some of those dollars need to be invested. Highly liquid dollar securities such as US Treasuries provide one place to hold those funds while preserving their usefulness in a future period of stress.
The Treasury purchases themselves are therefore not what is keeping the Nifty calm. They are evidence of the reserve-building mechanism underneath it. There are two important qualifications. First, country-level US Treasury data can reflect custodial arrangements, so the $15.2 billion figure should not automatically be treated as an exact measure of direct RBI purchases.
Second, the reserve increase is not equivalent to discovering $136 billion of permanent national wealth. The swap programme also creates future dollar liabilities. While spot reserves have risen sharply, analysts expect part of the headline increase eventually to reverse as those obligations mature. That distinction matters because the same programme that strengthened the external buffer has also created a domestic monetary consequence.
The dollar solution has created a rupee-liquidity problem
When the RBI acquires foreign currency, it injects rupees into the domestic banking system. The scale of the recent forex mobilisation therefore created an unusually large domestic liquidity surplus. Banking-system surplus liquidity reached around Rs.11.6 lakh crore earlier in September. The RBI has since begun selling government securities to drain cash from the system. It sold Rs.50,000 crore of bonds in the first tranche and plans total September OMO sales of Rs.1 lakh crore.
The policy chain is straightforward. The RBI attracts dollars, reserves rise and rupee liquidity increases. Excess liquidity pushes money-market rates lower, so the central bank sells bonds or uses FX swaps to drain cash and strengthen monetary transmission. One source of risk has therefore been converted into another. India has a larger external buffer, but the RBI must manage the domestic liquidity created in the process.
The 10-year government bond yield has already moved to roughly 7.1%, while markets are pricing a meaningful probability of further RBI tightening as oil and inflation remain elevated. The new reserves are useful, but they are not free.
Where does the thesis break?
The current system remains resilient only while its buffers are large enough to absorb the pressure. The most difficult scenario would involve several stresses arriving together: oil remaining above $100, inflation rising, the RBI tightening, bond yields moving higher, earnings weakening, FPI selling restarting and SIP growth slowing. In that environment, DII capacity to absorb foreign selling would also become less dependable.
The buffers would then stop operating independently and correlations across the market could rise. That is the kind of environment in which a market that has looked calm can become volatile quickly. There are already signs that the current calm has limits. The Nifty fell to a five-month low on September 15 as Brent approached $108 and global yields moved sharply higher. The buffers can alter the way a shock moves through the system. They cannot remove the underlying economic cost.
Where has the volatility gone?
India's low VIX does not mean investors have stopped paying attention to geopolitics, crude oil, the rupee or foreign selling. It reflects a market structure that has become better able to absorb some of those pressures. Foreign investors can sell equities while domestic institutions take the other side. Households continue directing more than Rs.30,000 crore into SIPs each month. External dollar pressure meets an RBI with almost $786 billion of reserves. Dollar inflows are being converted into liquid foreign assets, including US Treasuries. An economy still growing at 7.8% gives companies more room to withstand the shock.
The risk has shifted rather than vanished. Domestic equity flows have absorbed some of the volatility that might otherwise have appeared in index prices. RBI intervention has absorbed some currency volatility on the central bank's balance sheet. The resulting reserve accumulation has, in turn, created excess domestic liquidity that now has to be drained through bond sales and other operations
India VIX is therefore an incomplete measure of risk in the Indian economy. It tells investors how much volatility Nifty options are pricing over the next 30 days. It says much less about pressure on oil-sensitive corporate margins, the rupee, bond yields, central-bank liquidity operations or individual-company earnings.
That leaves a more useful question than simply asking why VIX is low: where has the volatility gone? In 2026, much of it appears to have been absorbed by domestic institutional balance sheets, the RBI's balance sheet and the widening gap between outcomes across sectors and individual stocks. The index can remain calm even when the market underneath it is carrying considerably more risk.
