The Indian stock market experienced a surge today, September 4, 2025, driven by positive sentiment surrounding the Goods and Services Tax (GST) Council meeting and its subsequent impact on various sectors. Both the Sensex and Nifty indices opened sharply higher, reflecting optimism about the government's GST overhaul aimed at spurring consumption and offsetting pressure from U.S. tariffs.

The Sensex gained 409.83 points, or 0.51 percent, to close at 80,567.71. During the day, the index reached a high of 80,671.28 and a low of 80,004.60. Preliminary data indicates the Sensex surged over 700 points in early trading. The Nifty 50 rose by 135.45 points, or 0.55 percent, ending at 24,715.05. The Gift Nifty traded around the 24,974 level, a premium of nearly 161 points from the Nifty futures' previous close, signaling a positive start.

GST Impact and Market Sentiment

The GST Council's decisions, particularly the rationalization of indirect taxes, are expected to positively impact the Indian stock market. The new GST regime, effective from September 22, 2025, introduces three GST slabs: 5%, 18%, and 40%. Finance Minister Nirmala Sitharaman announced that GST reforms would lead to a rate drop on 396 items, benefiting the common man.

Experts believe the GST reforms will simplify compliance, lower costs, free up working capital, and boost consumption, acting as an economic catalyst. Seema Srivastava from SMC Global Securities noted the reforms are expected to significantly impact the capital market and various industries, boosting economic growth, improving tax compliance, and increasing investor confidence.

Market Outlook

Shrikant Chouhan from Kotak Securities noted that Sensex formed a bullish candle on daily charts, holding an uptrend continuation pattern. For the bulls, 80,700 would be the immediate resistance zone, with a breakout potentially pushing Sensex towards 81,000–81,200. Key support zones are at 80,200 and 80,000, but a fall below 80,000 could make the uptrend vulnerable.

Overall, the Indian stock market is expected to maintain a positive outlook, driven by GST reforms and global cues.
