Still ahead, RBA:---Australian businesses are managing better than feared, but confidence remains too fragile to call the uncertainty over. Summary:NAB's business conditions index rose to +4 in July from +3 in June, though it remains below the long run trend of +7. Business confidence held at -6 in July, unchanged from June and still well below levels seen in February before the US-Israeli war on Iran began. Australian business conditions improved marginally in July while confidence remained fragile, a survey published Tuesday showed, with firms pointing to ongoing cost pressures even as renewed tensions in the Gulf pushed oil prices higher again. The bank added that cost pressures, combined with a softer forward demand outlook, suggest margins will remain under continued pressure.
