FX.co ★ Australia’s AIG Construction Index Slumps to -26.9 in October, Deepening Sector Contraction

Australia’s construction industry recorded a sharp deterioration in October, with the AIG Construction Index falling to -26.9, down from -5.0 in September 2026. The latest reading, updated on 03 November 2026, underscores a deepening contraction in the sector over the month.

The steep drop from September’s level suggests that weakness in construction activity accelerated markedly in October. While the index was already in negative territory, indicating contraction, the move to -26.9 signals a much more severe downturn. Investors and policymakers will be watching subsequent releases closely for signs of whether this decline stabilizes or extends into the final months of 2026.
