Key Highlights

  • The participation rate was 66.9 per cent, above the RBA's expectations.
  • More people looking for work pushed the jobless rate up even as employment grew.
  • The employment-to-population ratio was 63.8 per cent in the September quarter.
  • The RBA's summary does not explain every reason for the change in participation.

Picture two economies. In one, firms are laying off staff and the Unemployment rate rises. In the other, firms keep hiring at a steady clip, but even more people decide to look for work, and the unemployment rate still rises. The headline number can look the same in both cases. The story behind it is very different.

According to the Reserve Bank of Australia's November 2026 Statement on Monetary Policy, the Australian labour market in the September quarter looked more like the second economy than the first. The participation rate averaged 66.9 per cent over the quarter, above what the RBA had expected, and the Bank says unemployment rose more than anticipated partly because more people were joining or staying in the labour force.

What the participation rate measures

The participation rate is the share of the working-age population that is in the labour force — that is, either employed or unemployed and actively looking for work. People who are not working and not searching, such as many retirees, full-time students or full-time carers, sit outside the labour force and are not counted as unemployed.

That definition matters because the unemployment rate is calculated only from the labour force. If participation rises, the denominator grows. Whether unemployment then rises or falls depends on whether those extra participants find jobs.

Two other numbers from the RBA's economic conditions chapter make the mechanics clear:

  • The employment-to-population ratio was 63.8 per cent in the September quarter. This is the share of the working-age population that has a job.
  • The participation rate was 66.9 per cent. This is the share that is either working or looking.

The gap between the two — 3.1 percentage points of the working-age population — represents people who are in the labour force but without work. Dividing that gap by the participation rate (3.1 divided by 66.9) gives roughly 4.6 per cent, which matches the September quarter average unemployment rate the RBA reports. This is simple arithmetic on the published figures rather than an RBA calculation, but it shows how the three measures fit together.

The RBA's own words are notable here. The economic conditions chapter says "employment growth held up in the September quarter as expected." the overshoot in unemployment did not come from a hiring slump the Bank failed to see coming.

Instead, the surprise was on the Supply side. More people than expected were participating, so the labour force expanded faster than employment. The result was a September quarter unemployment rate averaging 4.6 per cent, compared with the 4.4 per cent the RBA had forecast in August, and a September monthly reading of 4.7 per cent.

The Statement does not break down who the additional participants are or why they entered or stayed in the labour force, so any explanation beyond the RBA's summary would be speculation. What can be said is that the Bank treats the higher participation as a genuine Factor in the jobless figures, not a statistical quirk.

Why the RBA cares about labour supply

Labour supply sits at the heart of the Bank's assessment of spare capacity — how much room the economy has to grow before it generates Inflation pressure. Governor Michele Bullock highlighted the constraint in her opening statement to the Senate Economics Legislation Committee on 28 October, saying "continued weak productivity growth means that the economy cannot grow strongly without putting pressure on inflation."

Stronger participation can, in principle, ease that constraint: more available workers mean employers have a larger pool to draw from. But the RBA is careful not to lean too heavily on that idea. Its November Statement notes that uncertainty about capacity cuts both ways. Pressures may be understated, or labour supply may be stronger, pushing unemployment higher.

That second possibility is exactly what the September quarter appears to show. If labour supply keeps surprising on the upside, the unemployment rate could rise further even without a deterioration in hiring.

Meanwhile, the Bank's read on wages suggests the labour market is not yet loose. The Statement says liaison contacts report elevated wage expectations, pointing to little easing over the next year, and the RBA has revised its wage price index forecasts higher, citing tighter capacity, higher inflation and inflation expectations.

How this fits the rate decision

On 3 November, the Monetary Policy Board raised the cash rate target by 25 basis points to 4.85 per cent, in a six-to-three majority vote. Its statement said: "Employment is expected to continue to grow, but the unemployment rate is projected to rise by more than expected in the August forecasts."

The Board's focus remains inflation. Headline CPI was 3.9 per cent over the year to the September quarter, and trimmed-mean inflation — the underlying measure — was 3.7 per cent over the same period. The monthly headline CPI indicator for September 2026 was 4.3 per cent year-ended. The statement said "Inflation remains elevated and recent data indicate that it is broadly based."

In that context, a rising jobless rate driven partly by labour supply does not, on its own, shift the Board away from tightening. The majority reasoned that "a further tightening in financial conditions is warranted to support the return of inflation to target." The statement gives no reasons for the minority's preference to hold at 4.60 per cent.

What the forecasts assume from here

The RBA's November forecasts have unemployment, as a quarterly average, at 4.7 per cent in December 2026 and rising to 5.1 per cent by December 2028, compared with 4.8 per cent in the August forecasts for end-2028. Those are RBA forecasts, conditioned on a cash rate path based on market pricing as at 28 October 2026 rather than any commitment from the Board.

The forecasts also assume growth stays below trend. If participation remains high while growth is soft, the arithmetic above suggests unemployment would have more room to rise.

The bottom line

The 66.9 per cent participation rate is a key reason the September quarter jobless rate overshot the RBA's August forecast. Employment grew roughly as expected, but more people joined or stayed in the labour force, so more of them were looking for work. That makes the rise in unemployment a mix of softer Demand and stronger supply rather than a simple story of Job losses. For the RBA, it is one more uncertainty in an outlook the Monetary Policy Board's statement says is subject to "heightened uncertainties", with the next Board decision due on 8 December 2026.
