India's stock markets saw a substantial boost as the Nifty 50 and S&P BSE Sensex rose nearly 4%, marking their strongest single-day increase in months. This rally added approximately ₹16 lakh crore (roughly $19.3 billion USD) to market value, driven by optimism following a temporary ceasefire between the US and Iran. However, analysts caution that the underlying risks, including elevated oil prices and slowing earnings growth, could hinder sustained momentum. Meanwhile, India celebrated a significant achievement in energy technology with the Prototype Fast Breeder Reactor at Kalpakkam achieving criticality, positioning the country as a leader in nuclear energy alongside Russia. In a contrasting trend, the retail investing frenzy appears to be cooling, with a 22% decline in new demat account openings, indicating a more cautious investor sentiment. Additionally, the Reserve Bank of India decided to maintain the repo rate at 5.25%, reflecting a careful balance between fostering growth and managing inflation risks amid global uncertainties.
