FX.co ★ Australia’s MI Leading Index Slips Deeper Into Negative Territory in September

Australia’s MI Leading Index edged down to -0.1% in September 2026 from a flat reading of 0.0% in August, signaling a modest deterioration in forward-looking economic momentum. The latest month‑over‑month data, updated on 14 October 2026, suggest that growth prospects have softened slightly as the index moves further into negative territory.

The previous reading for August 2026 had already marked a pause in positive momentum, with the indicator registering 0.0% compared with the prior month. September’s decline therefore represents a shift from stagnation to mild contraction in the composite signal, which tracks a range of indicators intended to anticipate turning points in Australia’s economic cycle.

While the month‑over‑month change is small, the move below zero will likely draw attention from investors and policymakers monitoring early signs of a slowdown. The MI Leading Index’s negative reading indicates that the balance of leading components is now pointing to slightly weaker conditions ahead compared with the preceding month.
