There's nothing worse than going into a time of economic uncertainty, when maybe your business might earn less or your job prospects could be slimmer, with a huge debt to worry about.
When interest rates are low, it's a great time to get rid of as much of what you owe as possible.
Any extra you can knock off the principal you have owing to the bank (or anywhere else) will reduce the amount you have to pay in future when interest rates invariably go up.
The investment in loan reduction now will pay off many times over.
Dropping interest rates create an opportunity for pain-free debt elimination.
When you have a loan come off a fixed term, and have the opportunity to move to a lower rate, keeping your payments the same means you pay it off faster without having to spend anything more.
Keeping a lid on your spending may not be the best thing for the New Zealand economy as a whole but for your individual household or business, it's probably the most sensible thing to do.
