- 6 min read
Based on market data as of 10:05 IST on 18 August 2026.
At a glance
Nifty is at 24,237.75 and Sensex is down 250+ points about 45 minutes into trade, marking a fifth consecutive losing session driven by the Hormuz Strait crisis.
Brent crude has surged to $91.56 and the rupee is under pressure at 95.68–95.72 per dollar, squeezing import-heavy sectors.
Pharma is the lone bright spot — Biocon's USFDA approval is helping it act as a defensive pocket — while IT and auto are lagging.
The setup
Forty-five minutes into Tuesday's session, the direction is clear and it is not encouraging. The Hormuz Strait — the narrow waterway through which roughly 20% of the world's oil passes — is at the centre of today's selloff. A vessel was struck by an unknown projectile, a crew casualty has been confirmed, and the US-Iran ceasefire has expired. Ship crossings through the strait have dropped to just 6 today against a 10-day average of 11. Markets opened under pressure and have not found a reason to recover. Yesterday's bearish themes are not reversing — they are deepening.
Top 5 sentiment drivers
Geopolitical risk premium. A vessel hit by an unknown projectile in the Hormuz Strait, a confirmed crew casualty, and the expiry of the US-Iran ceasefire are combining into a single, powerful bearish shock — strongly bearish at -0.80. Ship crossings at 6 versus the 10-day average of 11 show the supply disruption is not theoretical; it is already happening, and Brent crude at $91.14–$91.56 is pricing it in directly.
Risk factors. Beyond the Hormuz attack itself, the broader risk picture is deteriorating — strongly bearish at -0.72. Japan's 10-year JGB (Japanese Government Bond) yield has hit its highest level since 1996, signalling that the Bank of Japan (BOJ) may tighten monetary policy further, which historically pulls capital away from emerging markets like India. India's Current Account Deficit (CAD — the gap between what the country earns and spends in foreign exchange) is also widening, adding to the vulnerability.
Currency and commodity impact. The rupee is expected to trade at 95.68–95.72 per dollar today, weaker than yesterday's close of 95.6025 — moderately bearish at -0.65. Rising crude is the direct cause: India imports roughly 85% of its oil needs, so every dollar increase in Brent translates into higher import bills, a wider trade deficit, and more pressure on the currency. MCX (Multi Commodity Exchange) gold October futures dipped 0.55% to ₹1,55,090 per 10 grams (₹1,55,090/10g), as rate-hike fears offset safe-haven demand.
Global cues impact. Overnight signals were uniformly weak — moderately bearish at -0.60. US stocks closed lower as rising oil prices cancelled out enthusiasm around artificial intelligence. Japan's Nikkei and South Korea's KOSPI were both soft in the Asian session. The JGB (Japanese Government Bond) yield at a three-decade high signals a global monetary tightening cycle that is far from over, making risk assets like Indian equities less attractive to foreign investors.
Market volatility outlook. Five consecutive losing sessions on Nifty, an active geopolitical shock event, and a crude spike together point to elevated volatility — moderately bearish at -0.55. India VIX (Volatility Index — a measure of how much the market expects prices to swing in the near term) is likely rising, even though real-time VIX data is not yet confirmed. The options market is almost certainly pricing in a higher risk premium for the rest of this week.
Sectors in focus
Banking. Mildly bullish at +0.10 — the sector is holding up better than the broader market. ICICI Bank raised $750 million (approximately ₹7,162 crore) in dollar bonds, its third such issuance in a month, as Indian lenders collectively approach a record $9 billion (about ₹85,950 crore) in offshore bond sales. The RBI's (Reserve Bank of India) foreign-exchange swap facility is enabling this fundraising, which is positive for balance sheets, though broader risk-off sentiment is capping any meaningful upside.
IT (Information Technology). Mildly bearish at -0.35 — Infosys is among the top losers on Sensex in early trade. US stocks ended lower overnight, which directly dampens sentiment for Indian IT companies that earn a large share of revenue in dollars from American clients. Nasdaq's announcement of 23-hour trading from December 2026 is a structural positive for global tech access, but it offers no near-term relief today.
Auto and Manufacturing. Mildly bearish at -0.20 — no sector-specific bad news, but Brent at $91.56 is a direct headwind for automakers' input costs and for consumer fuel bills, which can soften vehicle demand. IndiGo appearing among top losers signals broader transport-sector stress from fuel costs. On the brighter side, Apar Industries' 22.52% monthly gain shows capital goods manufacturing is outperforming within the broader industrial space.
Pharma and Healthcare. Mildly bullish at +0.40 — the standout defensive sector of the session. Biocon received a supplemental approval from the USFDA (United States Food and Drug Administration) for Yesintek, a single-dose prefilled autoinjector biosimilar (a near-identical copy of a biologic drug). No negative USFDA actions — such as import alerts or warning letters — have been reported in the current window, making pharma a relative safe harbour as investors rotate away from cyclical sectors.
Global and macro backdrop
The global backdrop is uniformly cautious this morning. US equities fell overnight as oil's surge outweighed AI-driven optimism. Japan's 10-year JGB yield reaching its highest point since 1996 is a significant signal: it suggests the BOJ is moving away from its ultra-loose monetary policy, which for years pushed Japanese capital into higher-yielding assets like Indian equities. Any BOJ tightening can trigger a reversal of those flows. FII (Foreign Institutional Investor) provisional data for today is not yet available, but five consecutive sessions of Nifty declines strongly imply sustained net FII selling. DII (Domestic Institutional Investor — mutual funds, insurance companies, and similar domestic entities) buying is likely providing partial support and preventing a sharper fall. India's goods trade deficit widened to $85.7 billion in Q1 FY27, adding a structural layer of rupee vulnerability on top of the crude shock.
Risks to watch
Hormuz escalation: Any further vessel attacks or a formal military response could push Brent crude well above $95, intensifying pressure on the rupee and inflation expectations.
Rupee breach: If the rupee crosses 96 per dollar, the RBI may intervene, but sustained weakness would raise import costs and compress corporate margins across oil-linked sectors.
BOJ policy surprise: A faster-than-expected BOJ rate hike could accelerate FII outflows from Indian equities as Japanese investors repatriate capital.
India VIX spike: A sharp rise in India VIX could trigger stop-losses and amplify intraday swings, particularly in mid- and small-cap stocks that have less liquidity.
What this means for the rest of today's session
The early-session tone suggests the bears are firmly in control for now, and a meaningful recovery would need either a de-escalation signal from the Middle East or a sharp pullback in crude — neither of which looks likely in the next few hours. Pharma stocks may continue to attract defensive buying, while IT and auto face ongoing headwinds. Traders and investors should watch the Brent crude price and any geopolitical headlines out of the Hormuz region closely, as those two variables are the primary levers driving market direction today.
