NSE, BSE block overseas website access over cyber threat fears

India’s top stock exchanges — NSE and BSE — have raised eyebrows by temporarily restricting access to their websites for overseas users. While foreign investors can still trade on Indian markets, the sudden clampdown on website access has sparked intense curiosity and speculation across financial circles.

According to a Reuters report citing three sources, the decision was taken after a joint meeting between the exchanges earlier this week, where cybersecurity threats were a central topic of discussion. However, no actual attack has been reported so far. The exchanges are calling this a “precautionary measure” in light of heightened cyber vigilance.

The timing of the move is critical — it comes amid escalating tensions between India and Pakistan, both nuclear-armed neighbors. Though sources did not directly link the website restrictions to geopolitical developments, the coincidence has raised questions about possible cyber retaliation or espionage threats.

A BSE spokesperson told Reuters that as a critical Market Infrastructure Institution (MII), the exchange routinely monitors cyber risks — both domestic and international. The spokesperson confirmed that, “Based on such monitoring, websites/locations are blocked to protect users and systems,” adding that access is being restored selectively, on a case-by-case basis.

Markets, however, remain unaffected. Trading continues as normal for both domestic and overseas investors. This suggests the action is more defensive than disruptive, aimed at ensuring critical systems remain protected.

So, is this a smart cyber shield or a red flag for more serious threats ahead?

As cyberattacks on global financial infrastructure rise, India’s proactive response may serve as a model — or a warning — of what’s to come.
