Reserve Bank figures have shown that credit card debt has shot up to a record high and is concerned about the household debt-to-disposable income ratio,

Economists said some of the increase was because of populartion growth, but interest baring debt is increasing with people seemingly falling back in to bad habits such as adding to their credit card debt or increasing their mortgage.

This puts them in a vulnerable position should property prices fall while having high mortgage debt. Credit card interest rates can be high, and if they increase people can find themselves struggling to meet their debt commitments.
