The RBA is running out of ammunition and the government must pick up the slack.

The RBA has cut interest rates to a record low with further cuts likely this year.
This was a response to their own internal recalculation of the NAIRU that showed us to be even further from full employment than previously thought.
Add to this the possibility of a sudden actual real-world shock, and monetary policy is dangerously close to the lower bound of its effectiveness.
Government needs to take the hint and use fiscal stimulus and reform before the RBA runs out of ammunition and before wage and inflation expectations make a proper recovery even harder.


The RBA has cut interest rates to a new record low of 1.25 per cent. This was not a response to a sudden new market development. Rather, the RBA has recalculated its estimate of the ‘non-accelerating inflation rate of unemployment’ or NAIRU – the rate of unemployment consistent with low and stable inflation.

Previously the RBA believed the NAIRU was 5.25 per cent and an unemployment rate around 5 per cent would result in stronger inflation and wage growth.

Now they estimate the NAIRU to be around 4.5 per cent and that an unemployment rate even lower than that may be necessary to lift inflation back to within their target range, and improve wage growth for Australian workers.

The RBA consequently cut interest rates in the face of this new understanding and it should help support the economy. This added relief for mortgage holders could result in greater discretionary spending (retail, services, etc.) and additional debt being taken on for things like furniture and vehicle purchases. It should also cause a weakening of the Australian dollar that will improve export profitability and potentially divert some import spending to the employment of any currently-idle domestic resources.

The housing industry should also benefit directly from this. The RBA’s interest rate cuts combined with APRA’s potential reduction in lending ‘buffers’ should make new home purchases available to people who previously couldn’t access it. Greater borrowing capacity (and willingness) will support the home building and renovations industry.

Perhaps just as importantly, this new stimulatory environment is here to stay for an extended period. As recently as December last year, the RBA was forecasting that the next interest rate move was more likely to be upwards than downwards. Now, just six months later, the RBA has cut interest rates and there are probably more cuts coming. Downside risks are likely to continue into 2020 and beyond.

Moreover, the RBA may run out of interest rate ammunition before having returned the economy to the path towards full employment. Without a sudden positive international development or more ambitious fiscal response, this sets the scene for a somewhat impotent RBA, a prolonged period of economic underperformance and a low interest rate environment continuing for the foreseeable future. The government’s own wage and inflation forecasts – upon which much of their budget is based – could also be in jeopardy.

While low interest rates are, on the face of it, good for the housing industry, if they are a response to ongoing weakness in the broader economy and therefore, limited demand for housing, even the housing industry won’t be smiling.

Add to this the possibility of a sudden actual real-world shock, and monetary policy is dangerously close to the lower bound of its effectiveness. Estimates suggest that once the RBA reaches a cash rate of 0.5 per cent, further cuts won’t be stimulatory because the transmission mechanism would have been exhausted. Even quantitative easing has had mixed results around the world and may not be the economic panacea we would need.

Government needs to take the hint and use fiscal stimulus before the RBA runs out of ammunition and before wage and inflation expectations make a proper recovery even harder. Incoming tax cuts will be of great help and there is scope to bring forward some of the government's smaller and simpler infrastructure projects for immediate commencement. Federal infrastructure investment levels in general could also be even more ambitious – with appropriate costing and consideration for potential projects.

There is also scope for microeconomic reforms that improve productivity and efficiency across the economy. The replacement of stamp duty with a broader based land tax – or consumption tax like the GST – would be particularly beneficial for the struggling housing industry:

• It would facilitate downsizing for retirees, making larger homes available for new younger families;
• It would facilitate a more mobile and flexible workforce with people able to more easily relocate where jobs are available;
• It would provide State governments with a more stable source of revenue than stamp duties that tend to dry up just as the economy is in need of stimulus;
• It would help alleviate the intergenerational inequality that can emerge when one generation is lucky enough to be invested in the property market before a record-breaking boom.

Government has no excuse to sit on its hands. There is no shortage of productive investments and reforms to undertake, especially with borrowing costs so low – and falling.

While the story of independent central banks has been one of success for the last quarter century, monetary policy is not without its limits. It was never intended to entirely bail out the government from its responsibility for macroeconomic management. The coming years will test the government’s willingness and ability to pick up the economic slack that has emerged.
