Australia's central bank has cautioned that the rapid growth of the nation's A$3.9 trillion pensions industry poses new risks to financial stability. The sector, known locally as superannuation, is increasingly intertwined with the banking system, holding significant portions of banks' short-term debt and equity. The RBA highlighted that superannuation funds could amplify financial shocks, particularly during market stress, as seen during the pandemic. Challenges include managing liquidity as more people retire and the industry's growing exposure to offshore assets. The warning coincides with AustralianSuper appointing its first chief liquidity officer to manage these risks. The industry is expected to continue its rapid growth, outpacing the overall financial system. Regulators are closely monitoring the sector, especially its unlisted investments.
