Every Indian trading session begins with a set of cues already in place. By the time the NSE opens at 9:15 am IST, several major global markets have already completed their day. Asian markets — Tokyo, Shanghai, Hong Kong, Singapore — open earlier and are often the first to react to overnight developments from the United States or geopolitical events. US markets themselves close around 2:30 am IST, meaning their final moves are fully visible before Indian traders arrive at their desks. This sequence means that a sharp fall in the S&P 500 overnight, or a spike in oil prices due to a Middle East development, typically shows up in the opening moves of the NIFTY and SENSEX the following morning.

Indian markets do not operate in isolation; events in the United States, Europe, and Asia routinely set the tone before domestic trading even begins.

Today's session offered a clear example of this dynamic at work. Ongoing US-Iran tensions pushed gold prices up 1.43% globally, and while Brent crude eased slightly, the geopolitical uncertainty was present throughout the day. The rupee, which is sensitive to both crude oil prices and global risk sentiment, strengthened modestly — partly because oil did not spike further and partly due to RBI intervention. Meanwhile, the NIFTY IT index fell 0.30%, consistent with a global reassessment of technology-heavy trades that was also visible in news about quant funds facing losses tied to AI-related positions. These connections between a global theme and a specific domestic sector are a routine feature of how integrated markets now are.

It is worth understanding the mechanics behind this influence. Foreign institutional investors (FIIs) manage money across multiple countries and adjust their India allocations based on global factors such as US interest rate expectations, dollar strength, and risk appetite. When the US Federal Reserve signals concern about inflation — as the June FOMC minutes released this week showed — it can affect the US dollar, global bond yields, and consequently how attractive emerging market assets like Indian equities appear to foreign investors. Today, FIIs were net sellers of 532.86 crore, while DIIs stepped in as buyers of 2,057.79 crore, a pattern that reflects how domestic and foreign investor behaviour can diverge depending on their respective reference points. Understanding these connections helps investors contextualise daily market movements as part of a larger, ongoing global conversation rather than isolated local events.
