Brent crude declining is a positive signal. Perhaps the market is taking cues from President Trump's remark that the conflict will end soon and oil prices would plummet. But going by past experience, President Trump's words cannot be trusted," Vijayakumar added.The Indian rupee continued to trade under pressure near the 96.90 mark against the US dollar, raising concerns for import-dependent sectors. ..."A weaker currency increases imported inflation risks and creates margin pressure for import-dependent sectors such as oil marketing companies, paints, aviation and other consumption-driven industries," noted Hariprasad K, SEBI-registered Research Analyst and Founder, Livelong Wealth.India VIX, the market's fear gauge, stood at 18.44, extending its decline for another session. ..."A sustained move below the 18 mark will be necessary for stronger bullish confidence to return," said Aakash Shah, Technical Research Analyst at Choice Equity Broking.Institutional flows remained a concern. Foreign institutional investors continued net selling in recent sessions, while domestic institutional investors provided offsetting buying support. ..."The negative impact of the energy crisis will be felt in Q1 FY27. But if crude price continues to decline, the remaining quarters will be reasonably good," Vijayakumar said.Technically, Nifty's immediate support remains at 23,400, with resistance at 23,800–24,000. ..."Since the intraday market structure is non-directional, level-based trading would be the best strategy for day traders," said Shrikant Chouhan, Head Equity Research, Kotak Securities.Published on May 21, 2026
