Crude Oil, Not Rupee, Key to FII Flows as $105 Threshold Looms

Oil’s Rise Recasts the Risk Equation for Foreign Investors in India

JM Financial’s analysis points to crude prices—not the rupee—as the more important trigger for foreign equity flows.

Why crude has become a more immediate flow signal

For investors trying to understand foreign institutional investor (FII) activity, the rupee may be less of a cause than a consequence. JM Financial says past FII flows help predict the following month’s USD/INR movement, while earlier currency movements do not reliably predict FII flows. In the brokerage’s framing, the rupee is a “thermometer” of pressure, not the lever that sets foreign investment decisions in motion.

That distinction matters because currency weakness can accompany selling without being its original trigger. The analysis places oil earlier in the sequence: higher crude can worsen India’s import bill and weigh on risk appetite, while the resulting equity outflows can then add pressure to the rupee. It is a useful reminder that currency moves and FII flows may be connected, but the direction of that relationship matters.

The relationship changed after 2021

Over the full 20-year period, Brent crude had no meaningful link with monthly FII flows. JM Financial says that broad average masks a change in both the direction and shape of the relationship. Before 2021, oil and flows tended to rise together: the correlation between flows and monthly Brent changes was positive in each of the periods from 2006 to 2020. In that setting, higher oil could signal stronger global demand and risk appetite.

Since 2021, the relationship has turned negative, according to the brokerage. That makes the reason for an oil-price move relevant: a rise associated with supply threats can hurt an oil-importing economy and unsettle investors. The shift also helps explain why a single long-term correlation may fail to capture the risk facing markets now.

Outflows deepen as Brent crosses higher bands

The historical ranges in the report show how sensitive flows have been at elevated oil prices. Below $60 a barrel, average monthly FII flows were an inflow of $0.9 billion, and 63% of months recorded net buying. In the $60–75 range, average inflows were $0.7 billion. Above $75, the averages turned negative: outflows were $0.6 billion at $75–90, $1.5 billion at $90–105 and $4.1 billion above $105. Only one of the seven months in the highest band saw net inflows.

JM Financial describes $75 as a point above which flows turn negative, with selling becoming severe beyond $105. The figures are historical averages, not a mechanical forecast: the sample sizes vary across price bands, and oil is one influence on investment decisions. Still, the pattern gives investors a framework for assessing why a sharp crude move could matter more than a modest change in the currency.

Recent episodes underline the sequence

The report links earlier recoveries in FII flows to easing oil prices. In August 2022, FIIs invested $6.8 billion as Brent fell to $100 from $123 in June. In 2026, inflows of $2.5 billion in July and $2.4 billion in August coincided with Brent in the $84–91 range; flows reversed in September as crude rose to around $114.

March offered a sharper example: Brent climbed 45% to $103.1 from $70.9 a barrel, while FIIs sold a record $14.2 billion of Indian equities. The rupee weakened from an average of 90.7 per dollar in February to 92.8 in March, 93.6 in April and 95.6 in May. The timing supports the brokerage’s argument that oil rose first, selling followed, and currency weakness came alongside or after the outflows.

The pressure has persisted despite supportive domestic signals. FIIs sold $14.9 billion in FY25, $21.9 billion in FY26 and $12.7 billion in FY27 so far, or $17.7 billion including October 2026 month-to-date. In Q1FY27, GDP grew 7.8% year on year even as FIIs sold $13.4 billion. Earnings growth has recovered, and the brokerage says valuations at a 5.8% earnings yield, or 17.1 times, are supportive—but “cheap is not enough.”

Key Highlights

• JM Financial identifies crude, rather than the rupee, as the stronger signal for FII flows.
• FII flows have historically turned negative above $75 Brent, with heavier average outflows above $105.
• The oil-flow relationship shifted from positive before 2021 to negative thereafter, the brokerage says.
• Recent episodes show oil-price increases preceding or accompanying foreign selling and rupee weakness.
• Strong GDP growth and supportive valuations have not, on their own, brought a sustained FII turnaround.

Investor Note: The $105 level is a historical risk marker in JM Financial’s analysis, not a guaranteed trigger for future selling. Investors may want to watch crude prices alongside FII activity and currency moves, while weighing the possibility that domestic growth and valuations may not be sufficient to offset external pressures.
