Bank of America flags rising rates risk for Australia’s super sector

Bank of America has issued a warning that rising global interest rates could pose significant risks to Australia’s A$4.5 trillion superannuation sector. Mark Cabana, the bank’s head of interest rate strategy, noted that current borrowing costs are not yet high enough to slow the US economy, suggesting that rates may need to climb further. The US Federal Reserve’s benchmark rate is currently between 3.75% and 4.00%, while government bond yields have surged to levels not seen in decades. Cabana expressed concern that financial conditions would worsen if rate expectations moved into the high-4% to mid-5% range.

The warning is particularly relevant for Australia because superannuation funds have substantial investments in global equities, including major US technology companies. If interest rates rise enough to trigger a major repricing of stocks, bonds, or private assets, these movements could impact retirement portfolios. Australian financial markets are already feeling the effects, with the 10-year government bond yield climbing above 5%, property prices falling, and the ASX remaining below its August peak.

Despite the risks, Bank of America’s warning does not predict an inevitable financial downturn. Strong economic growth and the artificial intelligence investment boom continue to support corporate earnings and markets. However, the higher yields climb without a corresponding slowdown in economic activity, the greater the risk that central banks will need to tighten further, potentially pushing financial markets beyond investors’ ability to absorb higher borrowing costs.
