SYDNEY, AAP – Investors have pushed the Australian share market from lower to higher and overlooked fears about economic sanctions on Russia which have plagued Wall Street.

The ASX turned positive shortly before 1200 AEDT as the commodity-based share categories of materials and energy each rose by two per cent.

Commodity prices have surged since Russia invaded Ukraine. Traders are worried about supply difficulties. Brent crude oil last traded for $US104.97 per barrel.

The share market was mixed however, with the heavyweight category of financials down by almost one per cent.

The biggest losses were in consumer discretionaries, telecommunications and property. Each fell one per cent.

The benchmark S&P/ASX200 index was up 14.8 points, or 0.20 per cent, to 7111.3 points at 1200 AEDT.

The All Ordinaries index rose 12.8 points, or 0.17 per cent, to 7398.1 points.

In the US, President Joe Biden will soon reveal more about his plans to tackle Russia and inflation.

Mr Biden will give his State of the Union speech and is expected to heap pressure on Russia to withdraw from Ukraine or be economically isolated.

He will also call for more cars and semiconductors to be made in the United States. This would reduce the chance of supply-chain difficulties forcing prices and inflation higher.

In Australia, the economy raced back after the impact of last year’s Delta lockdowns.

The December quarter national accounts showed the economy grew by a hefty 3.4 per cent, rebounding from a 1.9 per cent contraction in the September quarter.

Annual growth rose to 4.2 per cent.
