If you look at things from a lending perspective, a number of the loans that were funded over the last couple of years were assessed at serviceability rates of between 7 and 8.5%. A large portion of 2009 saw an increase of first homebuyer activity. From personal observations, I would expect a great deal of FHB and borrowers in general to come into difficult times if they were forced to pay rates of 10% when coming from average rates of 6% or so. Some may adapt, but a lot wouldn't. The employment rate can be as low as it wants, but if people cant service their loans, I dont think the banks and the economy will be to worried about the employment rate.
A large number of loans were in arrears when we were paying 9% not to long ago. People were at the brink of losing a lot, retail spending had virtually come to a stand still.
The average loan amount is higher now than it was back then, so how the general community could cope with 10% for a couple of years beats me.
Most loans are pretty much assessed at 8.5% servicability these days. Factor in the 0.8% discount you get from banks, a bank is only lending to you if you can service approx 9.3% interest rates anyway...
