Weak Monsoon Forecast Rattles Markets

The India Meteorological Department predicted rainfall will fall below 90% of the long-period average this year, the lowest in 11 years. This forecast triggered immediate selling as lower monsoon typically leads to higher inflation and threatens agricultural output. Analysts flagged that weak rainfall could pressure multiple sectors and complicate the central bank’s inflation management.

MSCI Rebalancing Amplifies Late-Session Selloff

The final 30 minutes of trading saw intense selling pressure as the MSCI May 2026 index rejig took effect. Four Indian stocks including MCX and Indian Bank were added to the MSCI Standard Index, while RVNL and Kalyan Jewellers were removed. Around a dozen stocks also exited the MSCI Small Cap Index, triggering heavy passive fund flows and elevated trading volumes that dragged the Nifty lower before a partial recovery.

Geopolitical Tensions and Oil Price Swings

Uncertainty over a US-Iran peace deal prompted investors to lock in gains after April’s strong rally. Brent Crude futures fell 19% in May but remain 27.3% above pre-war levels. As the world’s third largest crude importer, India faces elevated oil price risk that could fuel inflation and weigh on corporate margins. Traders remained cautious about potential disruptions to supplies through the Strait of Hormuz.

Sector Losses and Volatility Spike

Power Grid fell over 4% to lead Sensex losses, while IndiGo dropped 3% ahead of quarterly results. Bajaj Finance, UltraTech Cement, Tata Steel, Sun Pharma and NTPC each declined over 2%. India VIX surged 9% to 16.35, signaling heightened market anxiety. Tech Mahindra and HCLTech bucked the trend and gained nearly 2%, while broader markets outperformed with small-cap and mid-cap indexes rising 0.7% and 3.2% respectively on earnings optimism.
