Commonwealth Bank and St George today announced an increase to their 3 year fixed rate to around 7.29% before any discounts. This increase comes 3 weeks after they followed other lenders in reducing their fixed rates down to levels that have not been seen for quite some time. Deciding whether to fix in or stay on variable is always a difficult question. No one knows what is going to happen with interest rates. Main advantage of fixed is that you have certainty of repayment so if one or two rate rises is going to totally blow your budget then perhaps it is time to fix in.
