Consumers might feel that they have been short-changed by their banks on deposit rate changes, with increases on average well below the rise in the cash rate since May, but business customers have fared much worse.

Comparison site Mozo reported that personal at-call savings account rates have increased by an average of 88 basis points since May 1, from 39 bps to 1.27 per cent.

Over the same period, business at-call savings account rates have increased by an average of 44 bps, from 16 bps to 60 bps.

Since May 1 the RBA has increased the cash rate target by 175 bps to 1.85 per cent.

“Business owners are being left behind,” said Mozo’s personal finance expert Claire Frawley.

Mozo said the highest business at-call rate is Goldfields Money’s offer of 2.4 per cent.

Other leading business at-call rates include Bank First’s offer of 1.30 per cent on a bonus saver account, Queensland Country Bank’s offer of 1.25 per cent, Bank of Queensland’s bonus saver rate of 1.1 per cent and AMP Bank’s six-month introductory rate of 1.05 per cent.
