Australia's largest pension funds are scrambling to protect portfolio returns as the Australian dollar's rally threatens to erode overseas investments. CBUS Super and Australian Retirement Trust have both reduced foreign currency exposure, with the latter diversifying into euros, yen, and pounds. The A$4.5 trillion retirement industry faces mounting pressure as the Aussie dollar climbs nearly 6% against the US dollar in 2025.

CBUS Super's Leigh Gavin revealed the fund's currency exposure has dropped to the high teens from the low 20s over the past three years. The Reserve Bank of Australia is closely monitoring this trend, noting that pension funds' hedge books are growing as they manage over half their assets offshore. The dollar's strength stems from commodity price surges and investor rotation away from US assets amid policy uncertainty.

Australian Retirement Trust's Andrew Fisher explained the strategy shift as redistributing currency exposure across multiple markets. With mandated contributions rising and the retirement sector expanding, funds are increasingly investing abroad in US stocks and European real estate. The central bank's recent rate hike, contrasting with expected Fed cuts, has further boosted the Aussie's appeal.
