From RBI MPC to U.S.-Iran peace talks to crude prices: Five factors that will impact the markets this week

Indian benchmark indices, the Sensex and the Nifty 50, ended last week with modest losses, dragged lower by a sharp sell-off on Friday triggered by the MSCI index rebalancing. The Sensex declined 639.61 points, or 0.84%, during the week, while the Nifty 50 slipped 171.55 points, or 0.72%, as investors navigated heightened volatility and persistent foreign fund outflows.

Looking ahead, market sentiment is expected to remain closely tied to geopolitical and macroeconomic developments this week. Investors will be tracking the progress of U.S.-Iran negotiations, broader diplomatic developments in West Asia, movements in crude oil prices, and the Reserve Bank of India’s monetary policy decision, all of which are likely to shape risk appetite and market direction in the week ahead.

Analysts believe that the market this week will largely depend on how these macro variables evolve over the coming days.

RBI MPC meeting in focus

The biggest domestic event for investors will be the RBI's monetary policy committee (MPC) meeting outcome on Friday. While the central bank had adopted a relatively growth-supportive stance earlier this year, the escalation of tensions in West Asia has complicated the policy outlook.

According to Emkay Global, the conflict has introduced a negative supply shock that poses risks to both growth and inflation. The brokerage noted that MPC members have largely shifted to a "risk-management" approach, acknowledging that monetary policy has limited ability to respond to supply-side disruptions.

While core inflation remains benign, policymakers are expected to closely monitor the impact of higher energy prices, possible fuel price hikes, and monsoon-related risks before signalling any major policy shift. Market participants will also watch the RBI's commentary on inflation, growth, and currency stability.

U.S.-Iran negotiations and crude oil prices

Geopolitical developments in West Asia remain the single most important external factor for Indian markets.

Hariprasad K., SEBI-registered Research Analyst and Founder of Livelong Wealth, said the markets are likely to remain highly sensitive to developments surrounding the U.S.-Iran situation.

"Any confirmation of a broader ceasefire arrangement or meaningful progress in diplomatic negotiations could significantly improve global risk appetite and trigger relief rallies across emerging markets, including India," he said.

Conversely, any setback in negotiations could reignite fears of supply disruptions and send crude oil prices sharply higher.

Crude remains a critical variable for India, which imports more than 85% of its oil requirements. Although Brent crude prices have retreated from recent panic-driven spikes, prices remain elevated. Sustained crude prices above the $100-per-barrel mark could worsen inflation, widen the fiscal deficit, pressure corporate margins and weigh on economic growth.

Foreign investor activity

Foreign fund flows will continue to be closely watched after a month marked by aggressive selling. Foreign Portfolio Investors (FPIs) sold Indian equities worth nearly ₹33,000 crore in May, taking cumulative outflows for 2026 to over ₹2.24 lakh crore, according to data cited by Geojit's Chief Investment Strategist V K Vijayakumar.

The persistent outflows have been driven by a combination of factors, including weak earnings growth in India, attractive opportunities in AI-linked markets such as South Korea and Taiwan, and the steady depreciation of the rupee.

Despite the heavy foreign selling, domestic institutional investors (DIIs) have remained a strong counterbalance, helping absorb much of the pressure and preventing deeper market declines.

Analysts say a meaningful improvement in sentiment will require foreign investors to return as buyers, particularly in large-cap stocks.

Rupee movement

The rupee's performance will remain another key monitorable for investors. The Indian currency has come under significant pressure in recent months amid rising crude prices, geopolitical uncertainty and capital outflows. It has weakened nearly 6% since the onset of the Iran conflict earlier this year, making it one of Asia's weakest-performing currencies.

However, the rupee staged a recovery towards the end of last week. Jateen Trivedi, VP Research Analyst - Commodity and Currency at LKP Securities, said the domestic currency gained around 0.8% to trade near the 95-per-dollar mark as crude oil prices softened amid growing optimism surrounding a potential U.S.-Iran agreement.

"Lower crude prices have eased concerns over India's import bill and provided support to the domestic currency. Technically, the rupee faces immediate resistance near 94.60, while 95.30 remains an important support zone in the near term," he said.

Key macro data releases

Apart from the RBI policy outcome, investors will also track a series of economic indicators this week.

April's Index of Industrial Production (IIP) data, final HSBC Manufacturing PMI figures, Services PMI and Composite PMI readings are expected to provide fresh clues on economic momentum. Market participants will also closely monitor GDP growth data and foreign exchange reserves for insights into the health of the broader economy.

Ajit Mishra, SVP, Research at Religare Broking, said heightened volatility is likely to persist amid the convergence of geopolitical risks, macroeconomic data releases and central bank commentary.

“Given the prevailing backdrop of geopolitical uncertainty, elevated volatility, currency fluctuations, and mixed global macro signals, participants should maintain a cautious yet selective approach,” he said.

Sectorally, energy, commodities, and selective domestic-facing themes continue to display resilience. At the same time, caution is warranted in sectors vulnerable to global growth moderation, currency volatility, and rising input costs, he added.
