Australian shares surge as inflation eases, Rio rallies

July 29, 2026 12:54 | News

Australia’s share market is trading at its highest value since March after headline inflation eased in June, softening the odds of an incoming interest rate hike.

The benchmark S&P/ASX200 index jumped 112.2 points on Wednesday, up 1.25 per cent, to 9,060, as the broader All Ordinaries gained 108.8 points, or 1.19 per cent, to 9,220.8.

Headline inflation fell to 3.8 per cent in the 12 months to June, down from four per cent in the year to May, indicating the Reserve Bank is making ground in its fight against inflation.

However, the central bank’s preferred trimmed mean price growth measure – or core inflation – held steady at 3.6 per cent, which was slightly below consensus estimates but still well above its two- to three-per cent target range.

“Today’s figures suggested the inflation fire was finally beginning to lose some oxygen, giving the Reserve Bank its first genuine sigh of relief in months,” Global X ETFs senior investment strategist Marc Jocum said.
