Thank you for the invitation to take part in this year’s Australian Strategic Business Forum. It is
very good to be finally back in Melbourne.
This Forum is being held at a critical time. As a country, we face some significant challenges, but we
have plenty of opportunities as well.
I would like to focus my remarks today on the challenge of bringing inflation back to target. This is an
important priority for the RBA. And in the spirit of this Forum being about strategic issues, I would
also like to briefly highlight two other strategic issues that are important to the Bank. The first of
these is the need to lift productivity growth in Australia. And the second is the changing nature of
money in our society.
After many years in which inflation was something that most people didn’t think too much about, it is
now a topic of everyday conversation. This is understandable as higher prices are putting pressure on
people’s budgets. In many countries, inflation is now running at its highest rate in decades. In the
United States and most of Europe, inflation is close to 10 per cent (Graph 1); the last
time that this was the case was in the early 1980s.
In Australia, the latest available reading on CPI inflation is for the March quarter. It showed an
inflation rate of 5.1 per cent. This was lower than in most other countries, but higher than it
has been at any time since 1991 and higher than we were expecting (Graph 2). The CPI for the June
quarter will be released next week and will show a further step-up in Australia’s inflation rate.
Another step-up is expected later this year. We will be publishing a full set of updated forecasts in the
Statement on Monetary Policy in early August.
The policy challenge for the RBA is to return inflation to the 2–3 per cent target range while, at the same time, keeping the
economy on an even keel. We don’t need to return inflation to target immediately, as we have long
had, for good reasons, a flexible medium-term inflation target. But we do need to chart a credible
path back to 2–3 per cent. We are seeking to do this in a
way in which the economy continues to grow and unemployment remains low.
It is certainly possible to do this, but the path ahead is a narrow one and it is clouded in uncertainty.
Global factors, including Russia’s invasion of Ukraine, are one source of this uncertainty. And
domestically, the path back to 2–3 per cent inflation will
be shaped by how the general inflation psychology in Australia evolves and how Australians respond to
higher interest rates. So these are some of the issues we will be watching carefully over the months
In charting the path back to 2–3 per cent inflation, it is
useful to understand the origins of the current higher inflation. There are three factors that I would
like to point to.
The first is the major interruptions to global supply chains that occurred alongside a surge in the demand
for goods as people switched their spending from services to goods during the pandemic (Graph 3).
Global supply chains are very long and any interruption anywhere in the chain causes ripples along the
whole chain. The resulting disruptions have increased firms’ costs and constrained their ability to
respond to the change in expenditure patterns. The result has been higher prices for goods in global
The second factor is Russia’s invasion of Ukraine, which has caused major disruptions to the global
markets for energy and food. This has directly affected CPI inflation in all countries and there are now
also second-round effects as higher energy costs feed into higher costs of transport and production.
The third factor is the surprising strength of demand in many economies. Household spending, in
particular, recovered more quickly from the pandemic than was expected. This reflected the success of the
vaccination campaigns in advanced economies and the unprecedented support to household finances from
fiscal and monetary policies. This policy support meant that, as the health situation improved,
households had the confidence and the ability to spend. The result has been strong growth in aggregate
demand and the emergence of tight labour markets in many countries. This has contributed to the higher
inflation we are now seeing.
Looking at this experience with hindsight, I can understand why some people might conclude that too much
support was provided by governments and central banks. But it is important to remember the context in
which this support was provided. At the time the decisions were made, the outlook was dire. In Australia,
tens of thousands of people were expected to die, our hospitals were expected to be overflowing, many
people were expected to lose their jobs and deep social and economic scarring was anticipated. It was a
very scary time.
In this environment, the RBA had a strong insurance mindset. Many other central banks and governments had
a similar mindset.
In our case, we wanted to do what we could to provide insurance for Australians against the potentially
catastrophic economic consequences of the pandemic. With the benefit of hindsight, it could be argued
that we took out too much insurance. But that is the nature of insurance. If the event you were insuring
against occurs, you are very glad you were fully insured. But if that event doesn’t occur, you are
left questioning your decision and wondering whether you could have saved some money.
Understandably, judgements will differ as to whether we over-insured or not. But in the highly uncertain
environment of the time, the right policy choice was to err on the side of too much insurance, rather
than too little insurance. I recognise though that while this approach meant we avoided some damaging
long-term scarring, it has contributed to the inflationary pressures we are now experiencing.
Looking forward, the path back to 2–3 per cent inflation
requires an increase in supply and some moderation of demand.
In terms of the supply side, there is a reasonable basis to expect that COVID-related disruptions to
global supply chains will ease further over the months ahead. Delivery times are improving and some
supply bottlenecks are easing as firms adjust to the new operating environment. The effects of this and
some rebalancing in consumer demand are now evident in some global markets, with declines in the global
prices of products as diverse as computer chips and timber (Graph 4).
More broadly, the prices of many commodities have also declined over the past few weeks, after the sharp
increases following Russia’s invasion of Ukraine. Oil and wheat prices have fallen recently as have
the prices of a number of base metals (Graph 5). These declines reflect increased concerns about the
strength of the global economy and some easing of supply problems. If the lower prices are sustained,
this will ease some of the current global inflation pressures. Even so, it remains possible that there
will be further interruptions to global supply, once again pushing up prices; the European gas market is
a particular area of concern here.
On the domestic demand side, the economy has bounced back strongly from the Omicron setback in January.
This is particularly evident in the labour market. Full-time employment is now around
7 per cent higher than its pre-pandemic level, and the unemployment rate has declined to
3.5 per cent – its lowest level in nearly 50 years (Graph 6). Underemployment
has also declined in recent months and job vacancies are at historically high levels across most
industries. This all suggests that the growth in demand in the Australian economy is pushing up against
the capacity of the economy to meet that demand.
For inflation to return to the 2–3 per cent target range, a
more sustainable balance between demand and supply is needed. Higher interest rates will help achieve
this through moderating growth in aggregate demand. With the COVID emergency now over, so too is the time
for emergency settings of monetary policy. The RBA was patient in withdrawing the insurance that was put
in place during the pandemic. We wanted to ensure a robust recovery and we were very aware that our main
policy instrument – the cash rate – was at the effective lower bound. That robust recovery
has taken place and the time for ultra-low interest rates is now behind us given that inflation is high
and the labour market is very tight.
In light of this assessment, the Reserve Bank Board has increased the cash rate by 125 basis points
over the past three meetings to 1.35 per cent and expects that further increases will be
required over the months ahead (Graph 7). These increases will help establish a more sustainable
balance between demand and supply in the Australian economy.
In considering the outlook for interest rates at its most recent meeting, the Board had an extended
discussion of the neutral real interest rate.
The concept of the neutral real interest rate is a useful one – it is the real interest rate that is
neither stimulatory nor contractionary. From a practical perspective, though, one of the challenges that
we face is that the neutral real interest rate cannot be observed or measured directly. It must be
estimated or inferred from other information. The staff at the RBA use a wide range of models and
techniques to do this.
These models produce a range of estimates and the estimates change through time as more information
becomes available. This means that there is considerable uncertainty around any particular estimate of
the neutral real rate. Having said that, most approaches suggest that the neutral real rate for Australia
is at least positive.
A related challenge is that the Board needs to translate any estimate of the neutral real
rate into an estimate of the neutral nominal rate, as the Board sets the nominal cash rate,
not the real cash rate. This translation requires an estimate of expected inflation. If we take the
2½ per cent midpoint of the inflation target as a reasonable estimate of medium-term inflation
expectations, this suggests that the neutral nominal rate is at least 2½ per cent. It would be
higher than this if medium-term inflation expectations were to shift higher.
I want to emphasise that the concept of the neutral rate is no more than one reference point for the
Board. It is not the basis of a mechanical rule and we are not on a pre-set path to achieve any specific
level of the cash rate. Rather, the Board will continue to be guided by the incoming evidence and by its
assessment of the outlook for inflation and the labour market. It is determined to do what is necessary
to return inflation to 2–3 per cent.
As I indicated earlier, an important consideration is how inflation expectations and the general inflation
psychology in the community evolve. If inflation expectations shift up and businesses and workers come to
expect higher rates of inflation on an ongoing basis, it will be harder to return inflation to target
– doing so would require higher interest rates and a sharper slowing in spending. It is in our
collective interest that this does not happen.
At the RBA, we track a wide range of measures of inflation expectations, including those derived from
surveys and financial prices. These various measures paint the same general picture: higher inflation is
expected for a short while, before declining back to target. As an example, the measure of inflation
expectations derived from indexed swaps suggests a high degree of confidence in financial markets that
the average inflation rate in Australia over the next 10 years will be 2 point something
per cent (Graph 8). These swaps also suggest the same for the average inflation rate over the
period between one and five years ahead, though inflation is expected to be higher over the coming year.
This assessment by financial markets that inflation is expected to return to the target range is
reassuring. But we are also paying close attention to the general inflation psychology of households and
firms. If people setting prices and wages were to believe that higher inflation will persist, they are
more likely to push prices and wages up. This could result in a self-reinforcing cycle: one in which
higher inflation leads to firms being more willing to put their prices up and agree to larger wage
claims, which then perpetuates the higher rate of inflation, and the cycle repeats itself. This is what
happened in the 1970s and it ended badly. There is little evidence of such a cycle at present and it is
important that this remains the case. The RBA is committed to ensuring that the current period of higher
inflation is only temporary and it will do what is necessary to bring inflation back to target. It will
be harder to do this if the inflation psychology shifts.
The other general factor that will shape the path back to 2–3 per cent is how households respond to higher interest
rates and prices. Household spending has so far been resilient, supported by household balance sheets
that are generally in good shape and stronger income growth. The household saving rate is still higher
than it was before the pandemic and many households have built up large financial buffers, including
through payments into mortgage offset accounts (Graph 9). But as my colleague, Michele Bullock,
discussed yesterday, not all households are alike. Recent borrowers and borrowers with lower incomes tend
to have smaller buffers. It is also worth remembering that around two-thirds of households do not have a
home loan. Another significant influence on household spending is housing prices, which are now declining
in many markets after a large run up. So the situation is complex, with many moving parts, and the Board
is monitoring it closely.
I would now like to turn briefly to the two other strategic issues I mentioned at the outset.
Lifting productivity growth
The first of these is the need to lift productivity growth.
I raise this issue because many of the challenges we face together as a nation would be made easier by
stronger growth in productivity. There is a limit to what can be achieved through management of aggregate
demand. The supply side matters too, and increasingly so.
Stronger productivity growth means a bigger economic pie and higher living standards. It can also put
downward pressure on prices and inflation. Further, strong productivity growth provides governments with
a greater capability to fund the many services that the public values. And it is the only way to sustain
stronger growth in real wages.
On the financial side, stronger productivity growth is likely to mean a higher neutral real interest rate
and higher real asset values. So savers would receive higher returns and our aggregate wealth would
Recent trends in productivity growth have not been particularly encouraging, with average productivity
growth slowing (Graph 10). Over the decade to 2014, labour productivity growth averaged
1.2 per cent per year; over recent years, it has been slower than this. In contrast, labour
productivity growth was in excess of 2 per cent during much of the 1990s. A similar pattern is
evident in many other advanced economies, and the underlying reasons are complex and not particularly
The strategic challenge for us as a nation is to do what we reasonably can to lift our productivity
growth. The good news here is that there is no shortage of ideas on how to do this.
The future of money
The other strategic issue that I want to highlight is the future of money and the nature of the monetary
A lesson from history is that what a society uses as money changes with technology. And once again, recent
advances in technology are changing the nature of money. Most money these days is digital and is able to
be moved around very quickly. In Australia, most people can now move money between bank accounts in less
than 10 seconds any time of the day or the week – not the days that it used to take. And on
the horizon is the possibility of programmable money, which contains self-executing code that triggers a
payment when a specified condition is satisfied. Also on the horizon is the potential tokenisation of
bank deposits, which could facilitate the tokenisation of other physical and financial assets. This, in
turn, could unlock a wave of innovation and productivity growth across financial services.
A second lesson from history is that money works best when it is backed by the central bank or by the
state. The backing by a central bank engenders trust, encourages widespread acceptance and provides
stability in times of stress. In the past, privately backed money has all too often ended in losses for
investors and financial instability. While I don’t think of most of the crypto universe as money, the
recent collapse of the ‘TerraUSD stablecoin’ serves as a reminder of this point.
The strategic issue here for central banks and governments is how to capitalise on the benefits of the new
technologies and new forms of money, while at the same time preserving the stability and other benefits
that come from a system underpinned by central banks. This is likely to require a strong regulatory
regime to deal with payment stable coins and perhaps central banks issuing a form of digital currency.
These are issues that we are working on with other regulators in Australia and other central banks, given
their potential to reshape our financial systems.
Before I finish, I would like to welcome the announcement today by the Government of the details of the
review of Australia’s monetary policy arrangements and the Reserve Bank. The terms of reference are
appropriate and the Government has appointed a first-class panel. The review is also welcomed by the
Reserve Bank Board and the Bank’s staff. It is an opportunity to take stock of our monetary policy
arrangements and make sure that they are fit for purpose for the challenges ahead. We look forward to
participating in this process and listening to and learning from others.
Thank you for listening today and I look to forward to answering your questions.
