Bank of Queensland’s relatively weak deposit base compared to its rivals and rising costs driven by compliance and risk management are expected to weigh heavily on its results when it reports next week.

That is the view of Citi broker Brendan Sproules, who told clients on Thursday that BoQ’s performance were likely to disappoint, adding that the bank could miss expectations around net interest margins because it has failed to gather deposits to fund its loan growth as fast as its peers.
