Weekly Global Financial Market Review: US-Iran Tensions Influence

GLOBAL MARKETS WEEKLY ROUNDUP Indian, Asian & American Markets | Gold, Silver, Crude Oil & Currency Tracker Week Ending: Saturday, May 30, 2026

EXECUTIVE SUMMARY

Global financial markets this week navigated a complex web of geopolitical uncertainty, driven primarily by the ongoing US-Iran conflict and tentative ceasefire negotiations. While American equity benchmarks continued their record-breaking rally, Indian markets drifted lower under pressure from a weakening rupee, elevated crude oil prices, and persistent foreign institutional investor (FII) outflows. Asian markets delivered a mixed performance, with Japan emerging as a standout gainer. Precious metals remained elevated with gold trading near historic highs, while the rupee faced renewed headwinds against the US dollar.

1. INDIAN MARKETS

Sensex & Nifty 50 Performance India's benchmark equity indices ended the week on a broadly negative note, weighed down by geopolitical tensions in West Asia, inflationary concerns, and sustained selling by foreign portfolio investors. Nifty 50: Closed at approximately 23,547 on May 30, 2026, down roughly 1.50% on the day. During the week, the index oscillated between 23,687 and 24,089, reflecting indecisive sentiment. Mid-week, the Nifty had briefly touched 23,983 before reversing course. BSE Sensex: Ended the week around 74,775, declining approximately 1.44% in the final session. The index had touched an intra-week high of 76,627 before correcting under broad-based selling pressure. Sectoral Highlights Among sectoral indices, Nifty Metal (up ~1.48%), Nifty Auto, Nifty FMCG, and Nifty Pharma were among the relative outperformers during the week. IT stocks such as Infosys faced headwinds, while Coal India and ONGC were notable laggards. Persistent Systems gained after announcing a European acquisition, and Ola Electric received approval for a commercial EV scooter.

FII & DII Activity

Foreign Institutional Investors (FIIs) remained net sellers on May 29, offloading equities worth Rs 21,105.86 crore, while Domestic Institutional Investors (DIIs) provided partial support by buying Rs 16,764.14 crore worth of stocks. The persistent FII outflow reflects concerns over India's elevated valuations relative to global peers, imported inflation from high crude oil prices, and a weakening rupee.

Key Market Drivers

The West Asia conflict — particularly uncertainty around the US-Iran ceasefire and missile activity near the Strait of Hormuz — remained the dominant macro theme weighing on Indian investor sentiment. Geopolitical flare-ups drove crude oil prices higher, directly straining India's import bill and current account. Additionally, Goldman Sachs raised its India inflation forecast and flagged expectations of additional RBI rate hikes through the year.

2. ASIAN MARKETS

Japan — Nikkei 225

Japan was the clear standout performer across Asian markets this week. The Nikkei 225 surged to a historic milestone on May 25, crossing the 65,000 mark for the first time ever, bolstered by reports of potential Strait of Hormuz reopening and a subsequent easing in oil prices. The index had earlier registered a strong single-session gain of 3.14% on May 21, closing at 61,684 following a robust Japanese trade data report showing April exports climbing 14.8% year-on-year, the fastest growth since January. SoftBank Group surged approximately 20% that session, tracking Nvidia's blockbuster AI earnings.

China — Shanghai Composite & CSI 300

Chinese equities delivered a mixed performance through the week. The CSI 300 traded in a narrow band, at times gaining 0.12% to around 4,914 and at other points slipping modestly. The Shanghai Composite hovered near the 4,179-4,948 range. Cautious investor sentiment in China continued to reflect concerns over domestic economic recovery momentum and muted consumer demand, even as government stimulus measures provided some underlying support.

Hong Kong — Hang Seng

Hong Kong's Hang Seng index remained in broadly choppy territory. While it briefly added 0.55% in certain sessions, it also retreated 1.38% in others, leaving the index oscillating around the 25,200 support zone. Technical analysis suggests the index is in a horizontal trend channel with a head-and-shoulders formation developing, indicating investor uncertainty. A decisive break below 23,922 would signal further downside, while a sustained move above resistance could renew bullish momentum.

South Korea — Kospi

South Korea's Kospi delivered one of the most spectacular performances of the week, surging 8.42% on May 21 to close at 7,815.59. The rally was powered by a resolution in Samsung Electronics' labour dispute, which saw shares of the index heavyweight gain more than 8.5%, while SK Hynix climbed 11.2% on AI semiconductor optimism. Analysts at Yuanta Securities expressed confidence in Kospi reaching 10,000 by year-end.

Australia — ASX 200

Australia's S&P/ASX 200 showed resilience, rising 1.62% to close at 8,731.7 in one of the week's sessions, supported by improved risk appetite following US-Iran ceasefire optimism and a pullback in crude oil prices.

3. AMERICAN MARKETS

S&P 500

The S&P 500 continued its exceptional winning streak, notching its ninth consecutive week of gains — the longest such run since late 2023. The index closed at record highs multiple times through the week, ending Friday's session at approximately 7,519-7,520. On Tuesday, May 26, the broad index gained 0.61% to close at 7,519.12, a fresh record. The S&P 500 climbed approximately 0.9% over the prior full week and has been powered primarily by technology and financial sector strength.

Dow Jones Industrial Average

The Dow Jones Industrial Average sprinted above the 51,000 mark for the first time in history during the week, a landmark milestone for the blue-chip index. By May 29, the Dow had crossed 51,000, with the index gaining 0.13% on the day. Earlier in the week, strong performances from IBM (+11.39%), Salesforce (+9.32%), Goldman Sachs (+1.13%), and Microsoft (+3.47%) fuelled the rally. For the prior week, the Dow had climbed 2.1%, its third weekly gain in four weeks.

Nasdaq Composite

The Nasdaq Composite also set new all-time highs, driven by continued enthusiasm for artificial intelligence and semiconductor stocks. The index gained 1.19% on May 26 to close at 26,656.18, another record closing level. Micron Technology was a headline performer, jumping 19% and crossing the $1 trillion market capitalisation threshold, after UBS flagged over 100% potential upside citing long-term AI-driven demand for memory chips. The Nasdaq rose approximately 0.5% over the prior full week, its seventh gain in the last eight weeks.

Macro Backdrop — Fed Policy & Inflation

The US macro environment remained complex. The latest PCE (Personal Consumption Expenditures) inflation reading for April came in as the highest in nearly three years, reinforcing expectations that the Federal Reserve will keep interest rates elevated well into 2027. Markets are now pricing in approximately an 11% probability of a rate hike in July, sharply up from 0.9% a month ago. Despite these headwinds, the 'buy the dip' mentality among retail and institutional investors alike has proven resilient, with leveraged ETF flows and options activity underpinning the rally.

4. GOLD & SILVER PRICES

Gold — International & Domestic

International (XAU/USD): Gold climbed for a second straight session on Friday, May 29, rising to approximately $4,539-$4,580 per troy ounce, lifted by reports of a potential 60-day ceasefire extension between the US and Iran. However, gold remains on track for a modest monthly decline of roughly 0.8%, pressured by elevated US interest rate expectations and a cautious Federal Reserve stance. Over the past year, gold has appreciated an extraordinary 37.99%, reflecting robust safe-haven demand amid the West Asia conflict and broader inflationary pressures.

Domestic India (MCX/Retail): Gold prices in India have surged to elevated levels, with 24-karat gold trading at Rs 15,764 per gram (approximately Rs 1.57 lakh per 10 grams) as of May 30, 2026. The 22-karat variety is priced at Rs 14,450 per gram, while 18-karat gold stands at Rs 11,823 per gram. On May 30, headlines noted gold topping Rs 1.62 lakh per 10 grams in certain markets. Domestic gold prices are influenced by international bullion rates, the rupee-dollar exchange rate, import duties (currently 15%), and GST (3%), with prices varying marginally across cities.

Silver — International & Domestic

International (XAG/USD): Silver traded at approximately $78.065 per troy ounce on May 25, gaining 2.45% in that session. The white metal has benefited from both its safe-haven appeal and growing industrial demand driven by solar panel manufacturing and electronics.

Domestic India: Silver prices in India are hovering around Rs 2,74,900 to Rs 2,80,000 per kilogram as of May 29-30, 2026. On a per-gram basis, silver is trading near Rs 280-285, reflecting the broader global rally as well as rupee depreciation pressures.

5. RUPEE & CURRENCY MARKETS

USD/INR Exchange Rate

The Indian rupee remained under significant pressure through the week, trading in the range of Rs 94.91 to Rs 95.75 per US dollar. On Tuesday, May 26, the rupee slipped 17 paise to 95.43 against the dollar in early trade, driven by month-end dollar demand and rising crude oil prices. By Wednesday, May 27, the currency opened lower at 95.75 per dollar. On Thursday, May 29, some respite emerged as the rupee strengthened to around 95.4 per dollar, extending a rally to a two-week high amid optimism about an Iran ceasefire and a subsequent easing in crude prices. As of May 30, the USD/INR rate is quoted near Rs 94.91-94.97. Reserve Bank of India Governor Sanjay Malhotra provided verbal support to the currency, stating that the RBI would do 'whatever is required' to ensure orderly forex market movement, and adding that the rupee appears 'undervalued' at current levels. This RBI intervention guidance helped arrest the currency's decline temporarily.

Key Rupee Pressure Points

Multiple structural factors are weighing on the rupee: persistent FII equity outflows; a widening current account deficit amplified by elevated crude oil imports; inflationary pressures that have prompted Goldman Sachs to forecast additional RBI rate hikes; and global dollar strength as Fed rate-cut expectations are pushed further into 2027. India imports approximately 85% of its crude oil requirements, making the currency acutely sensitive to energy price swings.

6. CRUDE OIL PRICES

Global Crude Benchmarks

WTI (West Texas Intermediate): WTI crude is currently trading near $91.07-$91.16 per barrel as of May 30, 2026. The commodity experienced significant volatility during the week, touching a high of $110.53 per barrel as recently as May 19 at the peak of West Asia tensions, before retreating sharply as ceasefire optimism gathered pace. On May 25, WTI fell 5.77% to $91.00 on a single day as reports emerged of potential Strait of Hormuz reopening. Brent Crude: Brent crude is trading near $97.78-$100 per barrel, having recently dipped below the psychological $100 mark for the first time in over two weeks amid US-Iran deal optimism. For much of May, Brent had remained well above $100, driven by fears of supply disruption through the Strait of Hormuz, through which approximately 20% of global oil trade passes.

India's Crude Oil Burden

As of May 26, crude oil was priced at $95.05 per barrel, translating to approximately Rs 9,020 per barrel at the prevailing rupee rate. The elevated crude environment is placing acute strain on India's economy: retail petrol prices stand at Rs 111.18-111.21 per litre and diesel at Rs 97.83 per litre. Domestic LPG cylinder prices are at Rs 912.50. State-run oil marketing companies face mounting financial burdens as they absorb the dual shock of higher global crude and a weaker rupee. The combination is driving India's import bill higher, widening the current account deficit, and exerting upward pressure on domestic inflation — a dynamic that complicates the RBI's monetary policy calculus.

7. OUTLOOK & KEY WATCHPOINTS

As markets head into the new week, the following themes will be closely monitored by investors: US-Iran Ceasefire Developments: Any formal agreement — or breakdown — in negotiations will be the single most impactful macro catalyst. A deal reopening the Strait of Hormuz would sharply reduce crude oil prices, ease inflationary pressures globally, and provide significant relief to the Indian rupee and equity markets. Federal Reserve Policy: The elevated PCE inflation print and rising probability of a July rate hike will keep US bond yields firm, limiting the upside for risk assets and maintaining pressure on emerging market currencies, including the rupee. RBI's Next Move: With Goldman Sachs forecasting additional RBI rate hikes in 2026, the central bank's policy stance and any intervention in the forex market will be crucial for rupee stability. FII Flows into India: A stabilisation or reversal of FII outflows is necessary for the Sensex and Nifty to reclaim higher levels. Sustained net selling above Rs 20,000 crore per day remains a headwind. Global AI & Semiconductor Momentum: The AI-driven rally in US and South Korean tech stocks — particularly in semiconductors — continues to attract global capital. Any negative surprise from a major AI company could trigger broader risk-off selling.
