Oil Pushes Foreign Investors Out of Indian Markets Again

Foreign funds sold about Rs 46,000 crore of Indian stocks in September as crude stayed high and the rupee sagged. That is roughly $4.8 billion at about 96 rupees per dollar, and it reversed two months of buying.

The sale is the number markets printed. The pressure sits in a larger crude bill, a currency the Reserve Bank of India is defending near 96, and household SIP money that is buying shares without fully covering the large-cap index foreigners are dumping.

Foreign Investors Unwound a Summer of Buying

NSDL and BSE figures compiled at the month’s close show foreign portfolio investors were net sellers of Rs 35,861 crore of stocks through September 29, then sold another Rs 10,148 crore on September 30. That took September to about Rs 46,000 crore of equity selling after net buying of Rs 20,200 crore in July and Rs 29,631 crore in August.

For 2026 as a whole, NSDL puts net FPI equity selling at Rs 2.6 lakh crore, already ahead of the Rs 1.7 lakh crore withdrawn in all of 2025, and the largest yearly net sale on that series. Motilal Oswal’s flow desk counts about $56 billion of FII equity withdrawals between October 2024 and September 2026, against about $55 billion of inflows in the eight years before that.

September was also the first month in two years in which FPIs were net sellers across the reported equity and debt books. They sold Rs 5,247 crore in the general debt limit, Rs 5,049 crore on the Voluntary Retention Route, Rs 10,431 crore on the Fully Accessible Route for government securities, and Rs 2,078 crore in hybrids.

Rs 46,000 Crore Left Indian Equities

The cash-market print is the one traders watch each evening. Depository ledgers settle a day later and split primary-market buying from exchange selling, which is why a heavy IPO week can make custody data look kinder than the tape. Daily custodian reports of FPI trades still showed a large exchange equity sale in the September 30 filing, with the rupee conversion printed at 96.0321.

SEPTEMBER FPI EQUITY FLOWS

Bond selling showed up on the same ledgers. FAR gilts, the slice that tracks in global indexes, took Rs 10,431 crore of net sales, and FPI volumes reported on NDS-OM are the market’s window on those outright government-bond trades. Fesa Wibawa, an Asia fixed-income manager at Aberdeen Investments, said the foreign selling should be read mainly as part of a global bond-market correction rather than a fresh verdict on India, and that the pullback was a place to add exposure slowly.

More Barrels, and More of Them From the Gulf

India buys almost 90% of the crude it runs, so the oil price feeds the current account, the rupee, and then portfolio flows. Kpler’s ship-tracking desk put September crude imports at about 5.3 million barrels a day, up about 600,000 barrels a day from August and 700,000 from a year earlier, as maintenance eased and refiners kept runs high on firm product margins.

Sumit Ritolia, Kpler’s senior manager for oil markets and refining, said Middle East volumes had recovered to around 3 million barrels a day, broadly back to pre-conflict levels, helped by higher flows from Iraq, Kuwait and Saudi Arabia and by better movements through the Strait of Hormuz. Russian arrivals fell to about 1.74 million barrels a day, the lowest since April’s 1.58 million, after 2.02 million in August and 2.66 million in July. Russia remains a central part of the basket, he said, and the latest drop is not a full turn away from those barrels.

INDIA’S SEPTEMBER CRUDE SLATE

Iraq’s jump is more than 250%, and Saudi volumes are up around 63%. Venezuela supplied about 215,000 barrels a day, Nigeria about 151,000, the United States about 141,000 and Brazil nearly 99,000. Refiners are paying for more barrels, and a larger share of those barrels is again priced off the Gulf complex that the Iran war has kept tight. NSDL-linked market tallies put the Indian crude basket above $115 a barrel during the September slide in the Sensex and Nifty, which each lost about 6%.

Why the Rupee Keeps Testing 96

The rupee closed at 95.83 per dollar on September 30, after a 0.7% drop on the month and a 1.2% drop in the July to September quarter. It had traded as weak as 96.1475 on September 29, still short of the record 96.96 hit in the previous quarter. State-run banks sold dollars, traders said, most likely for the Reserve Bank, and that cap is what kept the pair from a clean break through 96.

THE RUPEE BUFFER IN SEPTEMBER

• The close: 95.83 per dollar on September 30, after a 0.7% monthly fall and a 1.2% third-quarter fall.
• The deposits: Banks took in about $133 billion of FCNR(B) money under a concessional swap, part of $143.5 billion raised across that window, overseas foreign-currency borrowings and external commercial borrowings as of September 18.
• The reserves: Holdings briefly reached $785.7 billion, then stood at $765.9 billion in the week ended September 18 after a $14.9 billion drop.
• The oil hole: The merchandise oil deficit was $9.9 billion in August, and the current account deficit was $4.2 billion, or 0.5% of GDP, in the first quarter of 2026-27.

RBI staff writing in the September bulletin, with guidance from Deputy Governor Poonam Gupta, said West Asia tensions and high crude had weakened the rupee through August, that FCNR inflows brought a brief recovery in early September, and that those gains reversed later in the month as crude rose again. Headline inflation was 4.8% in August. The 10-year Indian government bond yield reached 7.12%, its highest since May, as the US 10-year traded around 5.21%.

Kunal Vohra, a strategist at BNP Paribas, wrote that macro buffers have risen with FCNR flows, that capital-flight risks have also risen with rate increases in developed markets, and that rising oil prices and commodity inflation remain a material challenge near term. Chief Economic Adviser V. Anantha Nageswaran said the swap window gives breathing room, and that the balance of payments will stay a challenge as imports and global competition for capital stay high.

The Buyer of Last Resort Is Indian SIP Money

Domestic institutions kept buying through the foreign sale. AceEquity figures put September DII net equity purchases at Rs 64,758.56 crore, the 38th straight month of net buying, taking that run to Rs 20,19,580 crore since August 2023. In 2026 alone they have put in Rs 6,21,027.97 crore. Monthly SIP contributions are running at about Rs 30,000 crore, and that stream is what lets mutual funds stand in the hole foreigners leave.

WHAT DOMESTIC MONEY IS COVERING

• The September cheque: DIIs bought Rs 64,758.56 crore of Indian equities, more than the FPI equity sale of about Rs 46,000 crore.
• The 24-month gap: Motilal Oswal counts about $177 billion of DII equity buying over two years, 23% more than the $144 billion they invested in the previous eight years.
• The SIP pipe: About Rs 30,000 crore a month of systematic plans is the cash that makes that DII bid repeatable.
• The holding skew: Foreign selling is concentrated in large-cap names that sit in the Nifty, while a large share of SIP allocation is mandated into mid-cap and small-cap schemes, so the domestic bid does not land on the same stocks.

That mismatch is why a month of heavy DII buying can still leave the Nifty lower. India also runs a large derivatives book relative to cash, so a sudden drop forces margin selling that the SIP bid cannot catch in a single session. Motilal Oswal’s markets desk put the same point in dollar terms: the rupee is the net of oil-import demand, FPI selling, and whatever capital is still coming in.

So don't ask: “How much money entered India?”

Ask: “What's the net dollar demand?”

Oil imports ↑ → Dollar demand ↑
FPI selling ↑ → Dollar demand ↑
Capital inflows ↑ → Dollar supply ↑

The rupee reflects the combined tug-of-war.

The Sensex closed September at 72,480, down 4,477 points. The Nifty closed at 22,620, down 1,460 points. Both lost about 6% on the month, and the Nifty finished September 30 at a six-month low. Gautam Chhaochharia, head of global markets India at UBS Group, tied the next leg of foreign flows to oil, and the bank said high crude, valuations and share supply would limit gains in the near term.

Oil will be the biggest factor determining whether India sees renewed foreign outflows.

The Hormuz Cycle Already Played Once This Year

This is the second time in 2026 that an oil spike has lined up with a foreign-investor exit. The Iran war and the first squeeze on Gulf supply hit in March. Equity outflows then were the year’s worst. Russian barrels filled a large part of the gap through the summer, and foreign buying returned in July and August after oil eased and Hormuz traffic improved.

THE 2026 OIL-AND-FLOW LOOP

1. March 2026: The Iran war and the first Asian oil-supply crunch send foreign investors out of Indian assets at the year’s hardest pace.
2. June 2026: Hormuz sees a three-week reopening, oil prices fall, and foreign buying of Indian assets prints a record on the CCIL series used by global desks.
3. July and August 2026: FPIs buy Rs 20,200 crore and then Rs 29,631 crore of Indian stocks as the summer inflow holds.
4. September 2026: Hostilities pick up, Gulf crude returns to India’s slate at higher prices, and FPIs sell about Rs 46,000 crore of equities plus FAR, VRR and general-route debt.
5. End-June 2026: India’s international investment position for June shows net claims of non-residents at $220.3 billion, after portfolio equity liabilities fell by $14 billion in the quarter.

The June inflow was a pause while the strait was easier to use, not a new foreign-investor cycle. September put the same oil channel back on, only this time India’s import volume was higher and a larger slice of it was Gulf crude rather than discounted Russian grades. US-based funds still hold the biggest pool of foreign portfolio equity, so a firmer dollar, a weaker rupee and a 5% handle on Treasuries cut the hedged return on Indian paper even before earnings are debated.

Brent Near $98 Leaves the Import Bill Standing

Brent traded around $98 a barrel in early Asia on October 1, after a September gain of about 14%, the largest since July. That is off the $100-plus prints that ran through late September, including sessions when futures poked above $103 and the Indian basket was quoted above $115. A $98 handle eases the next day’s dollar demand from oil companies. It does not unwind a month in which refiners lifted total crude intake to 5.3 million barrels a day and rebuilt Gulf supply to about 3 million.

Chhaochharia’s test still applies. If Brent stays high enough to keep the rupee pinned near 96, foreign desks will keep treating Indian large caps as a funding source, and SIP money will keep buying the other side of that trade. If crude slips and holds, the same desks that sold September have a path back, because they already bought July and August once Hormuz traffic improved. The import slate India is running now is larger, and more of it is priced in the Gulf, so the oil number that lets them return has to do more work than it did in June.
