SYDNEY, AAP – Banks have led the Australian share market higher despite US markets mostly closing lower from a technology fire-sale.

The S&P/ASX200 benchmark index was up 59.6 points, or 0.88 per cent, to 6799.2 at 1200 AEDT on Tuesday.

The All Ordinaries was higher by 51.5 points, or 0.73 per cent, at 7023.1.

The financial sector was higher by 1.74 per cent.

There were gains of more than one per cent for utilities, consumer discretionaries, health and industrials.

The only sector lower was information technology, which fell 4.56 per cent.

In the US, a big downturn in the technology-based Nasdaq offset stocks that rose on hopes the $US1.9 ($A2.5) trillion COVID-19 relief bill will spur economic recovery.

The Dow Jones hit a record intra-day high but the big tech stocks that have led Wall Street to scale successive peaks over the past year fell.

The prospect of a growing US economy has stoked fears of an inflation spike, sending the benchmark 10-year Treasury yield to near one-year highs and weighing on technology shares that rely on cheap funding for growth.

The Dow Jones rose 306.14 points, or 0.97 per cent, to 31,802.44. The S&P 500 lost 20.59 points, or 0.54 per cent, to 3,821.35 and the Nasdaq Composite dropped 310.99 points, or 2.41 per cent, to 12,609.16.

In Australia, business confidence has soared to its highest in more than a decade amid signs of a continuing robust recovery from last year’s recession, despite tapering of government support.

The National Australia Bank business survey showed confidence rose further in February to its highest since 2010, while conditions also returned to multi-year highs after dipping the previous month.

All states, territories and industries recorded increases, except retail.

The big miners were mixed. Rio Tinto climbed 1.68 per cent to $123.14, while BHP and Fortescue gained less than half a per cent.

AVZ Minerals was a notable improver after it said it had signed a supply deal with battery materials producer Shenzhen Chengxin Lithium Group.
