do brokers always get a heads up when an institution is going to increase rates...if so a heads up on ANZ would be good.
ANZ used to do that, but they stopped the formal practice a few years ago. Sometimes we do get a heads up but it can't be relyed on.
Edit: I just received an email from ANZ. They haven't announced anything, but are actively encouraging customers to rate lock. Clearly a there are people within the organisation expecting their rate to increase.
