The Australian Prudential Regulation Authority has conceded it has never collected specific data on the issue of how commissions impact superannuation fund balances.
Responding to a question on notice from Tasmanian Liberal Senator David Bushby, the regulator said it "does not collect data on commissions paid by superannuation funds as part of its current statistical collection".
Bushby had used a Senate Estimates Committee hearing to ask APRA officials whether they knew the degree to which commissions impacted superannuation fund balances.
"Do you have a feel for the percentage of funds that come in - particularly the retail funds - that attract commissions?" he asked.
The degree to which commissions affect superannuation fund balances represented a central element of the Industry Super Network's "compare the pair" advertising campaign, but was reliant on research from commercial ratings houses such as SuperRatings.
The regulator has fined two super funds for misleading sustainability and investment claims, citing ongoing efforts to curb greenwashing across the sector.
Super funds have extended their winning streak, with balanced options rising 1.3 per cent in October amid broad market optimism.
Introducing a cooling off period in the process of switching super funds or moving money out of the sector could mitigate the potential loss to fraudulent behaviour, the outgoing ASIC Chair said.
