Among the 867 corporates surveyed, hedging participation rose for both importers (up to 87%) and exporters (up to 73%), while businesses that both import and export edged down slightly to 78%.
Corporates still expect the Australian dollar to weaken over the coming year - to around 0.70 by end-March 2027 and 0.68 by end-September 2027 - but the pace of decline has slowed since the July survey.
CBA Economist and Currency Strategist Carol Kong said the shift reflects recent currency resilience.
"The shift likely reflects the resilience of the Australian dollar during the survey period between mid-August and mid-September, supported by a reassessment higher of Australian interest rates, a lift in commodity prices and strong risk sentiment despite the unresolved Middle East conflict," Kong said.
Business size remains the clearest divide in hedging behaviour. All businesses with turnover above $A4 billion hedge their FX exposure, with large corporates also using a broader toolkit, including options, forwards and cross-currency swaps.
"Larger corporates make greater use of more sophisticated hedging instruments because they have dedicated treasury functions, more complex funding requirements and broader risk management capabilities," Kong noted.
On risk, concerns differ by trade profile: interest-rate changes lead among importers, while exporters are far more focused offshore.
"US trade and tariff policy was the standout concern among exporters, cited by 29%, well ahead of the other risks. The result likely reflects exporters' direct exposure to changes in market access, tariffs and global trade flows," Kong said.
Businesses engaged in both importing and exporting were most concerned about AI and technological disruption.
