Jon Millin, executive director for fixed interest at Challenger Financial Services Group, said superannuation funds could fill a gap in the medium-term funding market.
Speaking at SuperRatings Day of Confrontation conference, Millin said the 5-10 year loan market cost banks more to hold financing beyond the traditional 3-5 year tenures.
Companies are over-reliant on short-term bank funding arrangements, while the local bond market has not matured in light of a decline in equities, according to Millin.
"How can it be possible that Australian investment-grade companies can't get five-year debt funding?" he said.
Millin said super funds could use floating notes and senior secured notes, that were traditionally used in leveraged buyout financing arrangements, to access the medium-term loan market.
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.
