Stock Market Today: Nifty, Bank Nifty, Top Gainers & Losers – September 17, 2026

As of 17 September 2026, the Indian market is trading slightly positive but cautious.

• Nifty 50: around 23,260–23,275, up roughly 0.2–0.25%. Intraday high was around 23,364 and low around 23,194.
• Bank Nifty: around 56,257, almost flat, down about 0.06% at the latest reported level.

What is driving today’s market?

The main issue is that Nifty is holding up better than Bank Nifty. The market is getting some support from domestic buying and short-covering, but global concerns remain:

• The US Federal Reserve raised rates by 25 bps to 3.75%-4%, keeping pressure on global risk assets.
• Crude oil remains elevated, around $105/barrel, which is a concern for India.
• The rupee is near ₹96/$, although RBI intervention/portfolio flows have helped stabilize it.
• FIIs were reported as sellers while DIIs provided buying support.
• Nifty’s move above 23,250 is important for today’s trading structure.

For your Nifty/Bank Nifty trading

Nifty: 23,250 is an important near-term reference. Holding above it keeps the index relatively stable; a sustained move toward 23,350–23,400 would indicate stronger intraday buying.

Bank Nifty: It is weaker relative to Nifty, so watch whether it can reclaim the 56,300–56,500 area. Continued weakness in major private/public banks could keep Bank Nifty under pressure.

Overall, today’s setup is Nifty mildly positive, Bank Nifty comparatively weak, with global/Fed/crude/rupee factors keeping volatility elevated.
