Opening Bell: Sensex Falls 484 Points, Nifty 50 Slips Below 23,500 Amid Rising U.S.-Iran Tensions

Market Update at 09:35 AM: IIndian equity benchmarks opened lower on Wednesday as escalating tensions between the U.S. and Iran dampened investor sentiment and triggered risk aversion across global markets. Concerns over rising inflation and elevated bond yields further weighed on equities during early trade.

At 9:17 AM, the Nifty 50 declined 166.60 points, or 0.71 per cent, to 23,459.45. The Sensex fell 484.19 points, or 0.64 per cent, to 74,706.06 in the pre-open session.

Broader markets also witnessed selling pressure. The Nifty MidCap index traded 0.83 per cent lower, while the Nifty SmallCap index slipped 1.09 per cent, indicating weakness across the broader market segment.

Among sectoral indices, the Nifty Realty, Nifty PSU Bank, Nifty Chemical, and Nifty Auto indices emerged as the Top Losers in early trade. On the other hand, the Nifty Pharma index outperformed the broader market and traded in positive territory, supported by defensive buying.

Investor sentiment remained cautious after U.S. President Donald Trump warned Iran of a “big hit” if a diplomatic agreement is not reached soon. The continuing geopolitical uncertainty between the U.S. and Iran pushed U.S. bond yields higher, as investors feared renewed inflationary pressures in the global economy.

Yields on longer-dated U.S. Treasury securities touched multi-decade highs, reflecting concerns that prolonged geopolitical tensions could keep inflation elevated and delay interest rate cuts. Rising bond yields typically reduce the appeal of equities, especially in emerging markets such as India.

Market participants are expected to closely monitor further developments related to the U.S.-Iran situation, along with movements in global bond yields and crude oil prices, for cues on market direction.

Pre-Market Update at 7:48 AM: The Indian stock market is expected to open lower on Wednesday, May 20, amid weak global cues, elevated bond yields, and uncertainty surrounding the ongoing U.S.-Iran conflict.

Gift Nifty trends also indicated a subdued start for domestic equities. Gift Nifty was trading near the 23,458 mark, down 101 points from the previous close of Nifty futures.

Asian markets traded lower, while Wall Street ended in the red overnight as rising Treasury yields intensified fears of prolonged higher interest rates.

Market participants continued to track developments related to the U.S.-Iran conflict. U.S. President Donald Trump said the United States would “end the war very quickly” with Iran, while Vice President JD Vance stated that the conflict would not become a “forever war.” However, the absence of a formal peace agreement kept investors cautious.

U.S. Treasury yields climbed sharply amid inflation worries and expectations of further rate hikes. The 30-year Treasury yield touched 5.20 per cent, its highest level since before the 2007 financial crisis, before easing slightly to around 5.18 per cent.

Japanese government bond yields also remained elevated. The 10-year bond yield stood at 2.795 per cent after hitting a 29-year high, while the 40-year yield touched a record 4.395 per cent. The 20-year and two-year yields also remained near multi-decade highs.

China left its benchmark lending rates unchanged for the 12th consecutive month. The one-year loan prime rate remained at 3.00 per cent, while the five-year loan prime rate stayed at 3.50 per cent, in line with market expectations.

The U.S. dollar hovered near a six-week high against major global currencies. The dollar index remained steady at 99.306.

From a derivatives perspective, the Put-Call Ratio (PCR) stood at 0.86, indicating cautious market sentiment ahead of weekly expiry. On the Put side, significant open interest was seen at the 23,000 and 23,500 strikes, making these key support levels for Nifty 50.

On the Call side, major open interest addition was observed at the 23,700 strike, while the highest open interest among out-of-the-money strikes was concentrated at 24,000, suggesting immediate resistance around that level.

Technically, Nifty 50 continued to trade within a broad consolidation range of 23,262 to 23,860. Immediate resistance is placed in the 23,758–23,860 zone, which also aligns with the 50-day moving average. A breakout above this range with strong volumes could push the index towards the 20-day moving average near 23,974.

On the downside, immediate support is seen around 23,550. A close below this level may intensify selling pressure and strengthen bearish sentiment. Until a decisive breakout occurs, traders are likely to witness range-bound movement with a cautious undertone.
