Ceasefire to Comeback: India's Sectoral Crosscurrents - May-June Digest

---

Mid-May 2026 set the tone for what was coming. On May 15, the Sensex slipped 160 points and the Nifty 50 fell 46 points to settle just below 23,650, as the rupee hit a fresh low against the dollar and crude oil prices ticked up — a quiet warning that the West Asia conflict, then in its third month, was nowhere near over. Oil & gas and metal stocks bore the brunt of the selling that day, while IT and services names, ironically, were among the buyers.

That calm proved temporary. Over the five weeks that followed — through June 19, the last trading session before the June 20-21 weekend — Indian markets lived through nearly every kind of volatility the West Asia conflict could produce: a renewed Iran-Israel flare-up that dragged the Nifty to a four-week low, a Reserve Bank of India policy hold that markets shrugged off, a dramatic mid-June pivot toward peace that powered a five-session rally, and finally, on the very last Friday, a brutal single-session IT crash that snapped the streak. By June 19 close, the Nifty had still added 1.54% and the Sensex 2.21% from the May 15 level — a modest net gain that masks just how turbulent the path there actually was.

Sectoral Performance - May-June 2026

🛡️ Defence — Still the Sector to Beat, Now at Fresh Record Highs

Through the volatility, Defence simply kept climbing. The Nifty India Defence index pushed to new all-time highs in mid-June: it surged 2.63% on June 17 alone to 9,371.20, and despite the IT-led market-wide selloff on June 19, the index still managed to add another 0.36% that day to close at 9,557.20 — one of only four sectoral indices in the green on the market's worst session of the window. Individual stocks have been even more dramatic: MTAR Technologies, Paras Defence and Space Technologies, Apollo Micro Systems, and Walchandnagar Industries have more than doubled, or risen as much as 147%, so far in FY27, while Astra Microwave Products is up 96% and Data Patterns, Zen Technologies, and Garden Reach Shipbuilders & Engineers have rallied between 43% and 66%.

The fundamentals back the price action. Hindustan Aeronautics Limited's order book hit a record ₹2.54 lakh crore by March 2026, up from ₹1.89 lakh crore at the start of FY26, and the company is separately reported to be eyeing roughly ₹90,000 crore of fresh orders over the next two years. Bharat Electronics Limited's order book stood at ₹73,882 crore as of April 1, including export orders of $495 million, with management flagging fresh opportunities in QRSAM, electronic warfare systems, naval radars, and submarines. Motilal Oswal has reiterated a 'Buy' on BEL with a target of ₹510, calling it its top pick in the space, even as the stock trades at a rich 42.4x FY27E earnings.

💊 Pharma — The Quiet Rotation Beneficiary

Pharma spent the window as the market's preferred hiding spot whenever the news turned bad. The Nifty Pharma index rallied for two straight sessions in early-to-mid June (+1.1% combined) to touch 24,414.45 on June 10, coming within striking distance of its 52-week high of 25,043.15 (versus a 52-week low of 21,149.90). On June 19 — the day the rest of the market cracked — Pharma was again one of the few indices to close higher, adding 0.30% to settle at 24,355.95, alongside Healthcare (+0.25% to 15,592.30). The pattern is consistent and clear: every time geopolitical or rate-driven risk-off hit the broader market through the window, Pharma and Healthcare were among the first places institutional money rotated into.

🏦 PSU Banks & Financials — Resilient Through the Whole Window

PSU Banks had a genuinely strong run across the five weeks. On June 5, even as the broader market closed lower on RBI policy day, Nifty PSU Bank surged 1.33% — one of the day's best-performing sectors alongside Media (+3.5%) and Realty (+1.76%). The strength continued into mid-June: the index advanced 1.42% on June 17 to close at 8,684.50, and gained a further 0.70% intraday on June 18 to 8,773.70, helped along by optimism around the National Stock Exchange's long-awaited IPO filing, which lifted sentiment across financial stocks with NSE shareholdings. Bank Nifty also had a standout RBI day on June 5, touching a session high of 54,732.20 as SBI, ICICI Bank, and HDFC Bank rallied on the rate hold.

🏠🚗 Realty & Auto — A Sharp Rally, Then a Choppy Give-Back

Realty's window was a story in two acts. Act one: a strong structural build — Realty was the second-biggest weekly gainer (after IT) for the week ending May 22, rising 2.4%, even as the broader index moved sideways. Act two: explosive, news-driven swings in mid-June. On June 15, as markets reacted to Trump's announcement of a signed preliminary US-Iran MoU, Auto, Financial Services (ex-Bank), and Realty indices each posted gains in excess of 3% in a single session, as falling crude improved the cost and demand outlook simultaneously across both sectors. But the rally didn't hold in a straight line — Realty slipped 0.59% on June 17 and a further 0.37% on June 18 as profit-booking set in, even as same-day headline coverage flagged Realty among the sectors "shining" by the close. Auto told a similar story: it joined the June 15 surge but gave back ground on June 17 (-0.52% to 26,752.50). On the corporate-action front, Bajaj Auto's board approved a ₹5,632.8 crore share buyback with a record date of June 24, while Maruti Suzuki — the heaviest-weighted Auto stock — saw choppy, headline-driven price action through the back half of the window.

🏭⚡ Metal & Energy — Whipsawed by the Same Crude Story That Drove Everything Else

Metal stocks rode the crude rollercoaster directly. They were swept up in the broad-based June 15 rally, then immediately gave back ground on June 16 — Hindalco fell as much as 3.61% intraday, JSW Steel and Tata Steel slipped too — as investors booked profits after "Monday's strong run." Nifty Metal then dropped 1.22% to 12,923.90 in early June 16 trade. The bounce-back came fast: Metal, Power, and Consumer Durables all posted gains of over 1% on June 17, and Nifty Metal added a further 0.67% on June 18 to 13,099.20.

Energy's window was more directly tied to the war-to-peace arc. On RBI policy day (June 5), Energy was among the sectors under pressure, alongside IT, Metal, Oil & Gas, and Telecom, as crude prices stayed elevated on conflict risk. By June 19, with crude having crashed from its earlier highs, Nifty Energy was one of the day's gainers, up 0.24% to 40,555.35 — direct evidence of the sector's two-sided sensitivity: downstream oil marketing companies benefit as crude falls, even as upstream explorers like ONGC and Oil India face the prospect of lower realisations on their own production.

💻 IT — From Quiet Outperformer to the Window's Biggest Casualty

No sector's story shifted more dramatically across the window than IT's. In mid-May, IT was actually one of the few sectors buying into broader weakness — Tech Mahindra and Infosys were among the May 15 session's top gainers even as the headline indices closed lower. By the week ending May 22, a rebound in IT stocks had led the market's entire weekly recovery, with the sector pulling Midcap (+1.4%) and Smallcap (+0.4%) names higher alongside it.

Then the script flipped. By June 5, Nifty IT was the session's notable laggard, down 0.42 % even as most other sectors gained on the RBI's rate hold. Through mid-June, IT stayed a step behind the broader rally — up just 0.9% on June 17 even as the index as a whole notched a fourth straight day of gains, then sliding 1.27% intraday on June 18 to 28,442.50, the only major sectoral index in the red even as financials and pharma pushed the benchmark to a fifth consecutive day of gains.

June 19 turned underperformance into outright crisis. Global IT bellwether Accenture cut its revenue guidance, explicitly flagging a $400 million hit to its Middle East business from the Iran conflict in the third quarter alone, with further impact expected in the fourth — its order book had separately been reported down sharply year-on-year. The news triggered an overnight rout in Infosys and TCS ADRs and a same-day crash back home: the Nifty IT index collapsed 5.74% to 26,833.45 from a previous close of 28,466.45, its sharpest single-session fall in months, dragging Infosys, TCS, HCL Technologies, Wipro, and Tech Mahindra all sharply lower, snapping the Nifty 50's five-day winning streak, and pulling the broader Nifty Services Sector index down 1.21% alongside it. The single session erased a meaningful chunk of the gains the rest of the market had built since June 12.

Nifty Movement

The Macro Backstop

Three pillars held the market together through five weeks of whiplash.

The RBI held the line on June 5, even as it turned more cautious on growth. The Monetary Policy Committee unanimously kept the repo rate unchanged at 5.25% with a neutral stance, but simultaneously revised its FY27 GDP growth forecast down to 6.6% from 6.9% and raised its inflation projection to 5.1%, explicitly citing the drag from elevated energy prices tied to the West Asia conflict. Markets initially rallied on the rate hold — Sensex touched an intraday high of 74,717.57 — before giving back the gains as Nifty IT weakness (-0.42%) and broader profit-booking took over; the Sensex ultimately closed 116.67 points lower at 74,243.34, and the Nifty 50 slipped 49.85 points to 23,366.70. The rupee, notably, staged a sharp recovery that same day, closing 85 paise stronger. The RBI also moved that week to liberalise FCNR(B) deposit and External Commercial Borrowing swap facilities — a structural step to widen the dollar-liquidity buffer just as global volatility was peaking.

GST collections stayed resilient, if moderated. India's gross GST collection for May 2026 (released June 1) came in at ₹1,94,184 crore, up 3.2% year-on-year from ₹1,88,172 crore in May 2025 — a slowdown from April's record ₹2,42,702 crore, though the government has noted that the headline growth figure is distorted by a one-time telecom spectrum payment in the year-ago base; adjusted for that, underlying growth was closer to 9%. Net GST revenue stood at ₹1,66,904 crore, up 3.3% year-on-year, while import-linked GST revenue jumped a sharp 19.1%, suggesting domestic demand for foreign goods held firm even amid global trade tensions. Cumulative April-May FY27 collections reached ₹4,36,887 crore, up 6.2% over the same period last year.

Domestic investors absorbed a historic wave of foreign selling — and FIIs finally began to turn. Domestic Institutional Investors bought a record ₹4.3 lakh crore worth of Indian equities in the first half of CY2026 (through June 9) — the highest H1 inflow on record, averaging roughly ₹4,000 crore every single trading day. That buying absorbed an equally record-breaking ₹2.8 lakh crore of Foreign Institutional Investor selling over the same period — the largest H1 FII outflow on record. Within the window, FIIs sold ₹4,440 crore on May 22 alone, even as DIIs injected ₹6,000 crore the same day. The most telling data point came on June 15: overseas investors returned to Indian equities for the first time after 13 consecutive sessions of net selling, buying a modest ₹200 crore (about $21.12 million) — a small number, but a meaningful signal — while DIIs simultaneously pumped in a further ₹3,189 crore.

Geopolitical Deep Dive: The Five Weeks That Ended the Iran War

The single dominant storyline of the window — arguably of the entire quarter — was the slow, halting, ultimately successful end of the 2026 Iran war, a conflict the International Energy Agency has characterised as the largest supply disruption in the history of the global oil market.

Mid-to-late May: stalemate. As of May 15, the Strait of Hormuz had been shut since early March, with Brent crude holding elevated and the rupee under pressure. An earlier April 8 conditional two-week ceasefire had briefly cooled tensions, but it proved fragile, and by late May the picture was still one of cautious stalemate — punctuated by a brief Friday rally on May 22 as investors "pinned hopes on US-Iran diplomatic efforts," with Brent trading above $100 but below $110.

Early June: a fresh flare-up. By June 8, tensions had escalated again — Iran reportedly launched missiles toward Israel following Israeli military action in Beirut, Brent crude jumped 3.5% to $96.50 a barrel, and Indian markets fell nearly 1%, with all major sectoral indices trading in the red. By June 11, reports of "intensified" US military action against Iran pushed the Nifty down to 23,161.60, its lowest close of the window.

June 12-15: the pivot. Everything changed on Friday, June 12, when Bloomberg reported that Washington and Tehran were nearing a peace deal ahead of the G7 summit, and President Trump said the US had "reached a great settlement" with Iran pending only the finalisation of paperwork. The Nifty surged 1.99% in a single session to 23,622.90, the Sensex jumped 2.3% to 75,527.95, and Bank Nifty surged 3%. Over the weekend, the draft solidified: on Monday, June 15, Trump confirmed that the US and Iran had signed a preliminary 14-point memorandum of understanding, extending the fragile April ceasefire by 60 days and committing to reopen the Strait of Hormuz — a waterway that carries roughly a fifth of the world's oil trade. Markets surged again, with Auto, Financial Services (ex-Bank), and Realty each rallying over 3% on the news.

June 16-17: scepticism, then formal signing. The euphoria cooled quickly on June 16, as analysts noted growing scepticism over how fast 14 million barrels per day of shut-in supply could realistically return to the market — metals sold off sharply on profit-taking even as FMCG, IT, and consumer durables held up. By June 17, the US and Iran had formally signed their interim ceasefire agreement, which included a full reopening commitment for the Strait of Hormuz and a reported $300 billion reconstruction fund for Iran — though President Trump warned Washington could still resume strikes if Tehran failed to honour the terms. Brent crude, which had peaked above $120 a barrel at the war's height, had by this point fallen to the high-$70s to low-$80s range.

June 17-18: a second story arrives — the Fed. Layered directly on top of the Iran de-escalation was the first policy meeting of new Fed Chair Kevin Warsh, sworn in on May 22 as the 17th Fed Chair. His two-day FOMC meeting concluded June 17-18 with rates held steady at 3.50%-3.75%, but a hawkish dot plot — a median projection of 3.8% by end-2026, up from 3.4% in March — signalled the new chair was establishing hawkish credentials early, a pattern Citi has noted is common for incoming Fed chairs. That hawkish tilt is precisely what kept IT under pressure even as the rest of the market celebrated the Iran peace deal, since higher-for-longer US rates raise the spectre of slower technology budgets among Indian IT's largely US-based corporate clients.

June 19: the two stories collide. Accenture's guidance cut — explicitly tying its $400 million Middle East revenue hit to the Iran conflict, on top of the Fed's hawkish shift — landed on Indian markets as a single, compounding shock, crashing Nifty IT 5.74% and snapping the index's five-day winning streak even as Defence, Pharma, Healthcare, and Energy held their ground.

For India, the macro stakes were always outsized. With over 85% of crude oil needs met through imports, every $10/barrel move in Brent shifts India's annual import bill by an estimated $15 billion. The war pushed local petrol and diesel prices up sharply between mid-May and early June, and briefly pressured the rupee to fresh lows — the very dynamic visible in the May 15 data point that opened this analysis window. A third, quieter thread ran underneath both stories all window long: trade. India's effective US tariff rate has stood at 18% since a February 2026 framework deal that saw Washington remove a punitive 25% duty in exchange for India's commitment to halt Russian crude purchases and deepen defence cooperation — down sharply from a peak of nearly 50% in 2025, with Bilateral Trade Agreement talks continuing in the background.

Crude Oil Movement

What's Next

The defining tension heading into the rest of June and into July is whether the peace framework signed on June 17 actually holds, given Trump's explicit warning that strikes could resume — and whether the market's scepticism about how quickly 14 million barrels per day of shut-in Hormuz supply can return proves justified. On the domestic front, watch whether the tentative return of FII buying on June 15 (after 13 straight sessions of selling) marks a genuine turning point or a one-off, and whether the Fed's hawkish dot plot keeps IT as the market's most volatile swing factor through the next two quarters. Policy-anchored sectors — Defence, Infrastructure, and PSU Banks — remain structurally best-positioned, backed by record order books and continued government capex. Realty and Auto's next moves will likely hinge on whether crude holds its post-peace-deal lows or drifts back up as Hormuz reopening logistics play out over the "three to six months" analysts have flagged for full normalisation.

Conclusion

The five weeks from mid-May to June 20, 2026 were a study in how directly geopolitics can run through to sector-level returns in Indian equities. A war that nearly reignited, then ended; a central bank that held steady while quietly turning more cautious on growth; a new Fed chair who opened hawkish; and a single overseas earnings call that erased days of gains in IT in one session — each left a visible, traceable fingerprint on a different corner of the market. Through all of it, the underlying machinery — resilient GST collections, a patient RBI, and a domestic investor base buying at a record pace — did what it has done through every shock since March: absorb it, and keep the index, on net, grinding modestly higher. As always, the sectors most tied to government policy showed the steadiest hands, while those most exposed to global cyclicality offered the sharpest reminders of how quickly sentiment can turn.
