Moody's gives big four banks thumbs up

The sharemarket closed flat with gains in bank stocks - which rose after international ratings agency Moody's endorsed Australian banks - offset by falls in big mining stocks.

The benchmark S&P/ASX 200 Index edged up 4.2 points, or 0.1 per cent to 5357, while the broader All Ordinaries index added 4.5 points, or 0.1 per cent, to 5350.6.

Moody's said its outlook on the big four banks was stable.

"As the investment boom in the resources sector moderates, and the decline in the terms of trade weighs on national income disruption, our outlook on the banks' credit standing remains stable because of their improved balance sheet strength, funding profiles and financial flexibility," Patrick Winsbury, a senior vice-president of Moody's, said.
