There's more cost-of-living pain on the way. The Reserve Bank has today hiked interest rates for the third time this year. The increase of 25 basis points brings the cash rate to four-point-three-five per cent. As a guide, it means if you have an 800,000 mortgage you'll be paying an extra 125-dollars each month. With all three rate hikes since February combined, that's more than 360 dollars a month out-of-pocket. The big four banks have been quick to move all announcing they'll pass on the increase in full and there could be more to come with financial markets forecasting an additional hike in the months ahead.
