International financial turmoil has led to the money market largely discounting the possibility of a rise in the official cash rate next month.
After the Reserve Bank's interim cash rate review on July 28, the market fully priced in a rise of 25 basis points to 2.75 per cent on September 15 and a one-in-three chance of 50 points.
But now the odds of any rate hike at the next review is put at just one-in-five, according to Credit Suisse's swaps-based indicator.
The Reserve Bank's statement on July 28 indicated it was inclined to remove the insurance rate cut it made in the immediate aftermath of the February earthquake.
But that was "provided current global financial risks recede and the economy continues to recover".
