Saudi Arabia’s stock market closed lower on Sunday following the deadly attack on Riyadh’s international airport, as heightened regional tensions weighed on investor sentiment.

The Saudi benchmark index ended down 0.2%, while Qatar’s market fell 1.5%. Outside the Gulf, Egypt’s blue-chip index dropped 2%, reflecting broader caution across regional equities, according to Reuters.

The security situation remained unsettled on Sunday. Associated Press reported that another projectile struck the airport a day after the deadly attack, adding to concerns over further escalation.

The disruption also extended to commercial aviation. Emirates, Etihad, flydubai and Air Arabia cancelled services as the airport closure affected travel to and from the Saudi capital, according to The Indian Express.

For investors, the immediate question is whether the disruption remains concentrated around aviation or develops into a wider threat to regional business activity. Further attacks, prolonged airport closures or an expanded military response could increase uncertainty for companies operating in the region.

For Indian markets, the next trading session will offer an opportunity to assess any spillover. Crude oil, currency movements and airline stocks are relevant indicators to monitor, but Sunday’s regional losses alone do not establish how Indian equities will respond.

Nivesh Street’s view: Saudi Arabia’s modest index decline should be distinguished from the severity of the incident. The financial impact will depend on the duration of disruption and subsequent developments—not simply the initial market reaction.
