Oil, rupee slide drag Nifty lower in first half of 2026

A nine percent fall in six months can quietly bruise a household portfolio.

For someone with ₹5 lakh parked in an index fund tracking the Nifty 50, that is roughly ₹45,000 gone on paper. Not a crash, perhaps. But enough to make a salaried investor pause before the next SIP.

The National Stock Exchange’s Nifty 50 entered 2026 with confidence. It reached mid-year looking tired, hit by costly oil, weak earnings, a falling rupee, and foreign investors pulling money out.

Oil shock rattled Dalal Street

The first half of 2026 was not really about one bad company result. It was about the market suddenly pricing in a more expensive India.

The US-Iran conflict disrupted the Strait of Hormuz, a key oil route. That pushed crude prices to levels last seen after Russia invaded Ukraine in 2022.

That matters deeply for India. The country imports about 85 to 90 percent of its crude oil needs. When oil rises, India pays more dollars, the rupee weakens, and inflation fears return.

The rupee slipping below 96 to the dollar added to the anxiety. For importers, students abroad, and families planning foreign travel, that number was not abstract. It meant real bills getting heavier.

Foreign investors pulled out hard

Foreign portfolio investors also pressed the sell button through much of the first half.

NSDL data showed foreign investors sold Indian equities worth ₹2,74,272 crore till June 30. Across equities, debt, hybrid funds, mutual funds, and alternative investment funds, they pulled out ₹2,12,872 crore.

That scale of selling hurts sentiment. It also creates pressure on large stocks, because foreign funds usually own liquid names first.

The pain was uneven. IT majors such as Infosys, TCS, Wipro, and HCL Technologies lost 34 to 38 percent this year. For many employees holding ESOPs, that is not just market talk. It affects personal wealth.

Other big names also struggled. Reliance Industries, HDFC Bank, ITC, HDFC Life, Jio Financial, Maruti Suzuki, and Mahindra and Mahindra fell 15 to 29 percent.

Yet the market was not a full washout. Adani Enterprises, Apollo Hospitals, Adani Ports, and Trent gained 15 to 35 percent. Coal India, Grasim, Nestle India, Titan, Sun Pharma, Hindalco, Power Grid, NTPC, and Max Healthcare rose 8 to 10 percent.

That split tells us something useful. Investors did not abandon India completely. They became choosy, and punished weak earnings harder.

Why rebound hopes are rising

The mood has improved because oil has cooled. Brent crude has fallen more than 20 percent from its March peak, and traded slightly above $73 a barrel on Tuesday.

Foreign selling has also slowed. In the second half of June, foreign investors turned occasional buyers in the cash market.

Arjun Guha Thakurta of Anand Rathi Wealth said the fall came more from uncertainty than domestic economic weakness. He pointed out that past geopolitical shocks usually caused corrections, followed by recoveries.

His broader point is simple. Markets fall often, even in long bull phases. The Nifty 50 has seen average yearly declines of around 18 percent, yet has usually recovered over time.

Seshadri Sen of Emkay Global Financial Services sounded more direct. He said Indian equities look ready for a solid second-half rebound, helped by easing external risks and domestic growth.

Sen also noted that valuations have cooled. The Nifty’s one-year forward price-to-earnings ratio has moved below its long-term average. In plain English, investors now pay less for each rupee of expected profit.

Earnings remain the real test

The catch is earnings. A market can bounce on cheaper oil and calmer global news. But a lasting rally needs companies to grow profits.

Some market watchers expect earnings recovery only from the third quarter of FY27. That means investors may need patience, not just optimism.

Thakurta said Nifty 50 companies could grow earnings by 12 percent in FY27 and 14 percent in FY28. He also said the index trades about 7 percent below its estimated fair value.

Shrikant Chouhan of Kotak Securities said Brent near $72 to $74 helps India’s macro picture. Lower oil can ease inflation and reduce pressure on the fiscal deficit.

Chouhan added that if crude falls below $65, India could see faster relief in oil, gas, and shipping costs. That would support companies and consumers together.

Banks and IT remain key. Chouhan said recent valuation compression in banks looks unfair, while the pressure on IT services looks more understandable.

The monsoon may decide mood

The market’s biggest local risk now is the monsoon. A weak monsoon can hurt rural income, push food prices higher, and slow consumption.

For urban investors, this may sound distant. It is not. Weak rural demand hits two-wheeler sales, FMCG volumes, fertiliser demand, tractors, and small finance lenders.

It also complicates inflation. If vegetables, pulses, and cereals rise, household budgets tighten. The Reserve Bank of India then gets less room to cut rates.

That is where the second half becomes tricky. Lower oil helps. But weak rains can steal part of that benefit.

For retail investors, the message is not to hunt for the perfect entry point. Markets rarely ring a bell before recovery. But blind buying after every dip is also lazy thinking.

A sensible investor should check asset allocation, avoid overexposure to one sector, and keep SIPs running if goals remain long term.

The first half of 2026 reminded investors that India can look strong and still wobble. The second half may bring a rebound, but it will need more than relief from oil. It will need earnings, rain, and confidence to move in the same direction.
