Australia’s central bank has issued a stark warning that persistently weak productivity growth will severely constrain sustainable real wages and complicate monetary policy.

At just 0.7 percent per annum, the new productivity assumption means that nominal wage increases much above 3.2 percent carry a serious risk of stoking inflation.

Reserve Bank of Australia (RBA) officials disclosed that they have reassessed their long-term productivity forecast downward from roughly 1 percent to 0.7 percent, a shift that forces a consequential downgrade to trend GDP growth and the economy’s “speed limit”.

This recalibration means wages must be more tightly aligned with productive capacity to avoid triggering price pressures.

The move also implies that recent wage gains may be harder to replicate in the years ahead.

RBA staff now assume potential national growth of about 2.0 percent, down from earlier assumptions of 2.25 percent.

At the Citi Australia and New Zealand Investment Conference, Assistant Governor Sarah Hunter emphasised that productivity is the key enabler of real wage increases without inflation.

She pointed out that raising wages substantially above the 3.2 percent benchmark could undermine disinflationary progress.

Nonetheless, Hunter acknowledged there may be scope for short-term “catch-up” wage growth in certain sectors, as long as broader inflation remains under control.

In its August Statement on Monetary Policy, the RBA detailed how weak productivity has translated to slower growth in household incomes and muted demand.

Structural weaknesses in capital investment and multifactor productivity have further weighed on growth.

The central bank noted that although wages continue rising, unit labour cost pressures remain elevated given the productivity drag.

Recent labor market data yields a mixed picture.

In the June 2025 quarter, the Wage Price Index rose by 0.8 percent (seasonally adjusted), translating to a 3.4 percent annual increase.

Private sector wages rose 3.3 percent year-on-year, while public sector wages climbed 3.7 percent.

These figures suggest modest momentum persists in wage growth, though not at a rate clearly sustainable under diminished productivity.

The 3.4 percent annual increase is slightly above the RBA’s benchmark of 3.2 percent.

The RBA held the cash rate at 3.60 percent in its September meeting, choosing to proceed cautiously given persistent inflation in services and resilient employment.

The central bank has signalled that future policy changes will remain highly data dependent, with its November meeting likely to hinge on fresh inflation and consumption figures.

Market expectations are cautiously tilting toward the possibility of a rate cut later in 2025.

Looking ahead, the RBA sees average wages growth easing to around 2.9 percent by late 2026 and 2027, leaving real wage gains near zero unless productivity rebounds.

The bank’s revised forecasts effectively lower the neutral rate, raise the bar for wage growth, and underscore the structural challenge confronting Australia’s economic trajectory.
