Australian banks continued last Thursday's downward trend, which was driven by ANZ Bank announcing an increase in bad debt provisions.

ANZ dropped 2.7 per cent to $26.01 and Westpac Banking shed 2.9 per cent to $33.50. AMP fell 0.5 per cent to $6.40.

"In this part of the world we don't need to be concerned about banks failing, but it's going to eat into profits a little bit, which concerns investors."
