Escalating tensions between the US and Iran over the Strait of Hormuz have triggered significant sell-offs and heightened volatility in global markets, with India and Japan facing acute economic pressures due to their heavy reliance on Middle Eastern energy imports. The conflict has spooked energy markets, sending Brent crude prices toward $100 and raising fears of imported inflation.
In India, the Nifty 50 index has declined nearly 14% in 2026, logging four consecutive weeks of decline. The index fell 2.6% on Monday, March 23rd, following an ultimatum from US President Donald Trump to Iran over the strategic Strait. This followed a 3.26% drop on March 19th, its biggest intraday fall since June 2024. Analysts attribute the fall to geopolitical tensions and a slump in heavyweight HDFC Bank shares.
The economic transmission is severe. Foreign investors have pulled over ₹80,000 crore from Indian equities in March alone, following outflows of ₹3 trillion in 2025 and ₹41,300 crore in January 2026. Karthick Jonagadla of Quantace Research notes this is "bigger than stock prices," impacting the rupee, liquidity, and valuations. India's vulnerability is stark: it imports 90% of its crude oil, with 45-50% sourced from the Middle East, and 90% of its LPG imports. Disruptions have already caused LPG shortages, affecting industries.
Jonagadla warns that every $10 rise in crude oil adds 55–60 basis points to India's Consumer Price Index (CPI), which currently stands at 3.21%. This imported inflation could narrow the Reserve Bank of India's (RBI) room for monetary easing, weaken the rupee further, and squeeze margins in fuel-intensive sectors.
Similarly, Japan's Nikkei 225 Index remains under pressure, trading around ¥51,900 after retreating from a February high of ¥59,330. Despite a brief rally in US markets after Trump announced talks with Iran, the index fell as Iran rejected claims of de-escalation and maintained the Strait's closure to enemy countries. Japan, a major energy importer, faces renewed inflation risks from rising oil prices, potentially forcing the Bank of Japan to consider interest rate hikes later this year. Business activity is already moderating, with the Manufacturing PMI dropping to 51.4 in March from 53.0 in February.
Market strategists advise caution. Sagar Lele of Paterson advises against panic selling and recommends a staggered investment strategy for those with cash. From a sector perspective, analysts identify pockets of resilience. Jonagadla's "relative safety basket" includes pharma & healthcare, FMCG, utilities, defense, and large export-oriented tech, which offer defensive demand and earnings resilience. Conversely, aviation and oil marketing companies are deemed most exposed to stress.
For now, the market is likely to reward resilience and earnings visibility over high-growth narratives as geopolitical uncertainty persists.
