The Week That Was — August 10–14, 2026 · Volume 01 · Issue 30
Hormuz Tensions Return, Crude Climbs,
and Nifty's Winning Streak Snaps
After two straight weeks of gains, Indian equities pulled back as a fresh round of Iran-US brinkmanship revived fears over the Strait of Hormuz, sending Brent crude toward $90 before it settled near $87. Tuesday's F&O expiry delivered the week's sharpest sell-off, and the index never fully recovered. Nifty closed Friday at 24,366.00, down 0.83% on the week — while DIIs stepped up with over ₹8,200 crore in buying to cushion the fall.
Editor's Note
Markets have a short memory for relief and a long one for risk. Just three weeks after the Red Sea blockade scare faded and crude retreated below $85, a fresh flashpoint between Washington and Tehran put the Strait of Hormuz back on trading desks' screens, and Brent was knocking on $90 by Tuesday. Nifty's response was measured rather than panicked — a single sharp expiry-day sell-off, followed by four sessions of quiet, grinding consolidation rather than outright capitulation. What stood out most this week wasn't the index move itself, but the composition beneath it: domestic institutions bought more than ₹8,200 crore even as foreign investors turned net sellers, and India VIX barely budged from its comfortable 11–12 range despite genuine geopolitical stakes. That combination — sticky domestic flows and contained volatility — is precisely the kind of market structure that rewards patient, systematic investors and punishes those who try to trade the headlines. Sector rotation was the other story of the week, with Defence emerging as a standout even as Autos and Pharma stumbled on stock-specific disappointments. As always, the lesson isn't to predict which geopolitical flashpoint fades and which escalates — it's to build a portfolio that doesn't need to know the answer in advance.
Market Overview
Nifty 50 closed Friday at 24,366.00, down −0.83% on the week against the prior Friday's close of 24,570.65. The Sensex ended at 78,009.25, down −0.62% for the week. Bank Nifty, which had already shown signs of fatigue through the middle of the week, closed at 57,491.10, underperforming the broader indices as both PSU and private lenders stayed under pressure.
This was a week that snapped a two-week winning streak. Monday opened on a constructive note as a weaker-than-expected US jobs report reduced near-term Fed rate-hike fears, sending Asian markets — and Nifty — higher. Tuesday, the week's F&O expiry session, delivered the sharpest single-day fall as renewed Iran-US tensions pushed Brent crude toward $90 on fears of a Strait of Hormuz disruption. Wednesday and Thursday saw the index grind lower in a tight, directionless range, with Bank Nifty logging multiple consecutive bearish candles. Friday brought a mild recovery attempt on softer US inflation data, but elevated crude and lingering geopolitical risk kept gains capped. Notably, India VIX stayed contained in the 11.3–11.7 band throughout, suggesting option markets are treating this flare-up as a slow-burn risk rather than an imminent shock.
5-session trading week: Monday August 10 through Friday August 14. Nifty snaps a two-week winning streak as renewed Iran-US tensions revive Strait of Hormuz blockade fears. Tuesday's F&O expiry session saw the week's sharpest single-day sell-off.

Macro Spotlight
Geopolitics reclaimed the driver's seat this week, even as domestic institutional strength kept the damage contained.
Iran-US Tensions Resurface, Reviving Hormuz Blockade Fears
Just as markets had digested last month's Red Sea scare, a fresh round of brinkmanship between Washington and Tehran put the Strait of Hormuz back in focus this week. Roughly a fifth of global oil supply transits the strait, and the mere threat of disruption was enough to push Brent crude from the mid-$80s to nearly $90 by mid-week before it settled closer to $87 by Friday — still a gain of roughly 4% on the week. For India, which imports over 80% of its crude requirement, this reintroduces the same inflation and current-account anxieties that weighed on sentiment through much of July.
DIIs Absorb Renewed FII Selling With Real Conviction
Foreign investors turned cautious sellers as the week progressed, particularly in the back half, but the damage was largely offset by an emphatic show of strength from domestic institutions. DIIs bought a net of more than ₹8,200 crore over the five sessions — including a single-day purchase of over ₹4,350 crore on Thursday alone — underscoring how sticky SIP-driven flows continue to provide a floor under the market even as foreign capital stays skittish. FIIs remain net sellers of Indian equities on a calendar-year basis, though August inflows had shown early signs of stabilizing before this week's reversal.
A Mixed Bag as Q1 FY27 Season Enters Its Final Stretch
Earnings continued to drive stock-specific action even as the index treaded water. Tata Motors' passenger vehicle business was the week's most notable disappointment, posting an 80% year-on-year decline in Q1 profit as Jaguar Land Rover margins came under pressure. AstraZeneca Pharma bucked the trend with profit growth of nearly 32%, while SBI, Godrej Consumer, L&T and Grasim were all in sharp focus through the week. With the bulk of large-caps having now reported, attention shifts to the smaller-cap names still due over the coming fortnight.
Sectoral Snapshot
Sector leadership rotated sharply this week, breaking from the broad-based participation seen in early August. Defence emerged as the standout theme, with names rallying 3–6% through the week on order-flow optimism, while Media and Consumer Durables were the only pockets of relative strength by Friday. PSU Banks bore the brunt of the selling on Monday itself, down nearly 2%, and the pressure spread to Realty, FMCG and Metals by Tuesday's F&O expiry. Auto and Pharma joined the laggards by Friday, with Tata Motors' passenger vehicle unit under particular scrutiny after its Q1 profit slump. Mid and Small-cap indices underperformed the headline benchmarks for the week — a reversal from their outperformance in the prior fortnight.
FII / DII Flow Tracker
FIIs turned net sellers as crude climbed and geopolitical risk resurfaced, but DIIs responded with one of their strongest weeks of buying since the July sell-off, comfortably absorbing the foreign outflow.
Directional buying resumes on weekend relief; DIIs stay supportive
F&O expiry sell-off proves retail-led, not institutional; both sides stay light
FIIs turn cautious as crude climbs; DIIs continue steady accumulation
Sharp DII buying decisively offsets FII selling
FIIs extend the selling streak; DIIs close the week as the dominant force
| Date | FII Equity Net | DII Equity Net | Note |
|---|---|---|---|
| Mon, Aug 10 | +₹320 Cr* | +₹900 Cr* | Directional buying resumes on weekend relief; DIIs stay supportive |
| Tue, Aug 11 | +₹259 Cr | +₹25 Cr | F&O expiry sell-off proves retail-led, not institutional; both sides stay light |
| Wed, Aug 12 | −₹380 Cr* | +₹900 Cr* | FIIs turn cautious as crude climbs; DIIs continue steady accumulation |
| Thu, Aug 13 | −₹511 Cr | +₹4,353 Cr | Sharp DII buying decisively offsets FII selling |
| Fri, Aug 14 | −₹667 Cr | +₹2,076 Cr | FIIs extend the selling streak; DIIs close the week as the dominant force |
*Figures marked with an asterisk are directional estimates pending confirmed provisional NSE/BSE data. The overall week saw FIIs turn net sellers of close to ₹1,000 Cr in the cash segment, while DIIs added more than ₹8,200 Cr — one of the strongest weeks of domestic absorption since the July sell-off.
Mutual Funds
This week is a useful reminder that pullbacks after strong runs are normal, not alarming. Two weeks of gains gave way to a modest, orderly retracement driven by a specific, identifiable risk — not a broad deterioration in fundamentals. With DIIs absorbing the bulk of foreign selling, portfolio-level damage remained contained. Investors with ongoing SIPs benefit from exactly this kind of volatility, picking up units at marginally lower NAVs without needing to time the Hormuz headlines.
Minor pullback after two strong weeks; continue core SIPs unchanged
Best positioned to rotate into emerging sector leaders like Defence and Media
Gave back some of its outperformance; maintain allocations through the dip
Underperformed for the first time in three weeks; stay the course on long SIPs
PSU and private banks both softened; valuations turning more attractive
Renewed geopolitical risk keeps the safe-haven bid alive; maintain a 5–10% hedge
RBI's rate hold continues to anchor yields; solid liquidity sleeve

Week Ahead — August 17–21, 2026
With the bulk of Q1 FY27 earnings now behind us, the coming week's narrative will likely be dictated by how the Iran-Hormuz situation evolves and where crude settles from here.
Strait of Hormuz Watch
Any concrete escalation — or de-escalation — in the Iran-US standoff will likely dominate price action. A confirmed disruption to shipping through the strait could see Brent test the $95–100 zone again, while a diplomatic climbdown could trigger a swift relief rally similar to late July's.
Closing Auction Session (CAS) Settling In
Now in its second full week, the new CAS mechanism for F&O stocks continues to produce sharp late-session reversals, as seen repeatedly through this week. Traders should factor wider intraday ranges into the final 15 minutes of trade.
Residual Q1 Earnings & Auto Sales
A handful of mid and small-cap names, along with a few PSU results, are still due. Monthly auto wholesale numbers will also be watched closely after Tata Motors' disappointing JLR-led miss this week.
Nifty Key Levels — Week of August 17
India VIX Watch: Holding near 11.3–11.7 — unusually calm given the headline risk; a spike above 13 would signal a genuine shift in sentiment.
