One of the country's largest mortgage lenders is to announce it is putting up its rates.
Later today, Permanent TSB will announce increases for new customers. The move follows other banks which have increased rates as a result of the credit crunch.
Earlier this week, Bank of Scotland Ireland increased its mortgage rates by 0.4 points.
Others who have increased rates on new business are Ulster Bank and First Active.
Permanent TSB will increase its rates on tracker mortgages for new business by between 0.2 and 0.25 points from the end of next month. In some cases, the rise will be 0.45 points.
Banks are increasing rates because they are being charged more to borrow from other banks.
Rates have risen by an average 0.35 points since the start of the year, due to the credit crunch, adding about €75 every month onto the cost of a €300,000 mortgage.
