Australia’s $4.5 trillion superannuation sector faces a risk that most fund members have not been told to watch: what happens if US interest rates keep climbing. Bank of America strategist Mark Cabana has warned that if the US Federal Reserve’s benchmark rate moves into the high 4% range or mid-5% range, the consequences for Australian super funds holding US equities and bonds could be substantial.
The current US federal funds rate sits at 3.75%–4%, according to ABC reporting. Cabana’s concern centers on what happens above that level. Australian super funds collectively hold tens of billions of dollars in US equity and debt markets. Higher US rates compress bond valuations, pressure equity multiples, and raise the cost of capital across the asset classes that super fund default balanced options hold in bulk. Bank of America’s view is an analyst opinion, not a published official RBA or APRA forecast. Mark Cabana’s assessment is that the risk threshold lies above where US rates currently are — meaning the scenario he describes has not yet occurred, but warrants preparation if it does.
For Australian superannuation members, Cabana’s warning does not signal fund collapses. The risk he identifies concerns market and valuation pressure on funds holding US assets, not a forecast of fund failure. Members approaching retirement may wish to discuss their fund’s asset allocation and withdrawal strategy with a licensed financial adviser.
Why the Super System Is More Exposed Than It Looks
Australia’s compulsory superannuation pool has grown to $4.5 trillion over decades of mandatory contributions. That pool has significant exposure to US equity and bond markets, which is the direct channel through which Cabana’s rate-pressure scenario would affect Australian members. Bank of America’s analysis argues that Australian super funds have structured their portfolios for a long accumulation phase, holding significant allocations in unlisted assets: domestic infrastructure, commercial property, and private equity. These assets generate long-term returns but cannot be converted to cash quickly if a fund needs to meet a spike in retirement drawdowns. The RBA’s current domestic rate setting adds a second pressure point: Australian household budgets and super fund return expectations are under simultaneous pressure from both the domestic cash rate and the potential for further US rate increases that Cabana identifies.
The scenario Cabana describes does not threaten fund solvency. APRA oversight, mandatory capital standards, and the structure of the super guarantee are designed to prevent fund collapse. The risk Cabana flags is narrower: potential valuation pressure on balanced options if both US rates and Australian rates remain elevated. Super account balances are investment-linked — they reflect the value of the underlying assets the fund holds and can rise or fall with market conditions. They are not guaranteed deposits. Members approaching the drawdown phase carry sequence-of-returns risk: a period of below-average returns at the start of retirement permanently reduces the balance available for the remainder of retirement. Reviewing the unlisted asset allocation in your fund’s default balanced option is the practical step. The next APRA quarterly superannuation performance and liquidity disclosure is the primary data point to watch for evidence of whether Cabana’s concerns are materializing in fund returns.
