Borrowers are likely to avoid an interest rate rise for at least another month.

In a survey of economists conducted by AAP, all 11 expected the Reserve Bank of Australia would leave the cash rate at 4.5 per cent for a third straight month at Tuesday's board meeting.

Meanwhile, the economists spoken to believe another increase by the central bank is will be unlikely until the end of the year after lower than expected inflation figures were released last week.

Nine of the 11 economists surveyed by AAP say rates will lift by a quarter of a percentage point by Christmas, increasing monthly repayments on an average $300,000 mortgage by $49.
