The problem with fixing your interest rate

The dramatic 2,5% reduction in interest rates since January this year has sent many borrowers running to their banks in pursuit of fixed rather than variable interest rates on their home loans and other debts.

Their hope is obviously to be able to keep their monthly repayments at the current low levels for at least the next few years even if the Reserve Bank should start to raise rates once again.

However, says Gerhard Kotzé, MD of the RealNet estate agency group, there are several problems with this strategy, the first being that most banks will charge borrowers a premium of between 1,5% and 3% to fix the interest rate on their bond, and will usually require that they do so for a period of at least two years.

The reason for this is that when you fix your rate, you are effectively asking the bank to take over your risk of future interest rate fluctuations, but in any case it means that if you are currently being charged the prime rate of 7,25% on your home loan, most banks would raise the rate to at least 8,75% if you asked them now for a fixed rate for, say, the next two years.

“This means that on a R1m loan, for example, you will be paying an additional R934 per month on your loan – and that you will effectively be “wasting” that money until and unless the prime rate actually does reach 8,75% sometime in the next two years. It also means that you will not benefit if the Reserve Bank lowers rates even more, which it is actually expected to do later this year.”

He says it is important to understand that in this scenario, the additional amount you will be paying every month will not help you shorten the term of your home loan or save you any money in the long run.

“On the other hand, if you can afford the additional R934, and you use it to reduce the capital portion of your R1m bond while staying on a variable interest rate, amortisation tables show that you stand to lower the total balance outstanding to R965 000 within a year, and to R928 000 within two years (compared to R952 000 without the extra payment).

“This means that if and when interest rates do rise, your minimum monthly repayment due will be calculated on a much lower capital balance. And the effect of that will be that if the interest rate does reach 8,75% in two years’ time, your minimum monthly repayment required will still be considerably less than you have been used to paying.”

In addition, says Kotzé, if you do this for two years, you will have shortened the total term of your bond by at least 12 months and cut some R69 000 in interest off the total cost of your home.

“Staying on a variable rate now means that you will also benefit from any further cuts the Reserve Bank may make in the next few months to try to stimulate the economy. And if you have an access-type bond, you will always be able to withdraw any additional amounts paid into your bond account should you need them in an emergency.”
