Yeah yeah. Bank targets 15 per cent return on equity. They’ve said that one before. What looked like a disappointing return in the boom years has in the past five become a reminder of just how far banks in the U.S. and Europe have sunk. But for Gail Kelly of Westpac, who just repeated the target on Thursday, it looks all too possible, as it does for Australia’s other big banks. Alas, that still does not make the sector look exciting.
