Another bank is predicting an upcoming OCR raise. 

ANZ has already picked three consecutive Official Cash Rate hikes in July, September, and October.

Now Westpac says it's becoming more of a possibility next month - but is more likely in September. 

Chief economist Kelly Eckhold says the Reserve Bank will work from specific indicators. 

"They're looking for indications that the peak in inflation will be even higher than they currently expect."
