Global Markets Today on 17 August 2026 See Australia Shares Fall as NAB Results Offset Miner Gains While Middle East Tensions Drag on Broader Risk Appetite

The global markets today on 17 August 2026 are shaped by a combination of corporate results, geopolitical risk, and oil market dynamics.

What are the global markets today doing on 17 August 2026?

Ans. The global markets today on 17 August 2026 are mixed: Australia shares are falling on weak NAB results and Middle East tensions, Asian markets are mixed (Hang Seng +1.42%, Straits Times -0.88%), oil is at $89.20 Brent, and the S&P 500 had a modest pullback from its record high on Friday.
