In the late 1980s, as the Iron Curtain fell, the US Army War College threw away its old Cold War playbook.
In its place, trainee strategists were taught to see the world as Volatile, Uncertain, Complex and
Ambiguous: or ‘VUCA’ for short. ² The implications were far-reaching. Out went the old
certainties. And in came a new approach that stressed the importance of approaching problems from
different angles, drawing on multiple perspectives and scenarios, learning from mistakes, making robust
decisions, and communicating openly about the uncertainties.
Where the military began, the business world followed: VUCA begat a million Harvard Business Review
articles. Inevitably perhaps, it lost some of its shine in the decades that followed. But today it’s
back – with a vengeance. The rules of global trade have been turned on their head. New geopolitical
realities are dawning. Artificial intelligence, the energy transition, demographic change and the long
shadow of COVID-19 are fundamentally changing our concepts of economic
activity and work. And Australia, like elsewhere, is seeking new sources of productivity growth. ³ With the
world in flux, companies, households and governments must change how they think, act and plan –
just like those army cadets of the 1980s. ⁴
Monetary policy cannot affect these profound changes. But it does have one key job – and that is to
ensure that, of all the things people do have to worry about, inflation is not one. High
inflation hurts everyone. It hits living standards, particularly for those on low and fixed incomes. And
it disrupts households and companies’ plans. The past few years have been a vivid reminder of that.
Around the world, core inflation reached multi-decade highs (Graph 1). Graph 1
Uncertainty rose sharply too. Forecasting prices during the pandemic was harder than at any time in
the past quarter of a century: for central banks (Graph 2) ⁵ – and for everyone else too. Graph 2
That left inflation much higher up peoples’ VUCA worry lists than it should be, harming livelihoods
and crowding out focus on the economic choices that households and companies should be spending their
time on. Our job is to put that into reverse – returning inflation to the background, where it
belongs. ⁶
In my remarks today, I want to review progress towards that goal. I’ll start with the good news
– inflation is down and employment is up. We are moving on from the narrow path. But monetary
policy must always look ahead – and here I want to discuss two decidedly VUCA risks that shape that
outlook: the prospects for world trade; and the degree of spare capacity in the Australian labour market.
I will conclude with some implications for monetary policy. Moving on from the narrow path
While Australia saw much the same pickup in inflation as elsewhere, our monetary policy response was
different. Interest rates rose significantly – but they never reached the levels seen in many other
developed economies (Graph 3). Graph 3
That was an explicit choice, grounded in our mission: to bring inflation down, but at a pace that helped
preserve sustained full employment. An implication of this strategy, clear from the start, was that just
as interest rates rose by less, so they would also fall less far – and less quickly.
There were always risks on both sides of this ‘narrow path’ – and people regularly called
them out. Some said the RBA should have tightened more to bring inflation down faster and earlier –
and clearly we could have. But that would have risked materially higher unemployment. Others said we
should have eased more quickly to help kickstart economic activity. And we could have done that too. But
it would have risked inflation being higher for even longer. In the Board’s judgment, both
alternatives would have left the Australian people worse off.
That is why the latest economic data are encouraging. Year-ended trimmed mean inflation, our preferred
measure of underlying price pressures, fell to 3.2 per cent in the December quarter,
0.2 percentage points lower than expected in November. Among other things that reflected lower
inflation in new dwelling costs, rents and market services – which had been stubbornly persistent.
Measured on a shorter two-quarter annualised basis, trimmed mean inflation was in the 2–3 per cent target range (Graph 4). Graph 4 While inflation has moderated, employment has continued to grow extraordinarily strongly. That’s
true compared both with other developed economies (Graph 5), and with our own history:
64½ per cent of the population now have jobs, the highest on record. Graph 5
By contrast, economic growth has been much more subdued, particularly in the private sector. But here
too there is now cautiously better news, with partial indicators suggesting that household spending
picked up in the December quarter. GDP growth is projected to rise back to trend over the forecast
period.
So we look to be moving on from the narrow path. But central bankers are paid to worry, not
celebrate. And monetary policy works with lags – so it must be set with an eye to the future,
not the past. I will now discuss two key uncertainties that shape that outlook. Key uncertainty 1: Global trade policy – VUC, but especially A?
To the naked eye, the four words in ‘VUCA’ seem just different versions of ‘chaos’. In
fact, their meanings are distinct. Volatility and complexity are the simpler concepts.
‘ Volatility ’ means rapid change, whether predictable or unpredictable –
and ‘ complexity ’ means a world of multiple overlapping causes and effects.
Uncertainty and ambiguity are slipperier. ‘ Uncertainty ’, in the classical
sense, means you know the model, but don’t know the parameters. So you have to estimate an imperfect
model-based forecast, which you can refine as you get more information.
‘ Ambiguity ’ means you don’t know the model, so any
model-based forecasts will break down, and feeding more information into those same models won’t
help. In situations of ambiguity – or ‘Knightian uncertainty’ ⁷ as
economists sometimes call it – judgement and instinct are as important as formal analysis.
These concepts can help us think through the implications for Australia of global trade policy uncertainty
– which is at a 50-year high (Graph 6). Graph 6
As economists, our inclination is to approach this as an analytical problem of classical uncertainty. We
might note for example that, from a macroeconomic perspective, Australia’s direct
exposure to US tariffs levied on our exports is limited (Graph 7). Graph 7
Such an analysis might quickly turn, however, to the fact that Australia is heavily integrated into, and
reliant on, the global economy more broadly – and particularly China (Graph 8). ⁸ Hence
the bigger macroeconomic risk for us would be if the imposition of US tariffs on third countries
triggered a global trade war that impaired our trade and financial linkages more broadly. As
Australia’s long history has shown, we thrive when trade, labour and assets flow freely in the
global economy, but we suffer when countries turn inwards. Graph 8
In principle, it is possible to estimate the quantitative impact of policy alternatives on Australian
activity and inflation using macroeconomic models, though the number of assumptions required is daunting.
It includes: the scale, scope and persistence of US trade measures globally; the extent of any policy
reactions in third countries (including both trade retaliation and domestic stimulus); the reaction in
financial markets, including crucially how the exchange rate adjusts; and the responses of global trading
firms, including both production and trade diversion.
Our February Statement on Monetary Policy included three stylised scenarios, involving
different sets of these assumptions. ⁹ These scenarios suggest some downward impact on
Australian activity; and an impact on inflation that could be either positive or negative, depending on
whether supply or demand effects dominate. But many other alternatives are possible too. Given the large
uncertainties at this early stage, only limited changes were made to our central projections for global
activity.
Up until very recently, financial markets appeared to be placing little weight on any severe adverse
scenario. Measures of implied volatility in equity, bond and most foreign exchange markets were subdued.
Estimates of equity risk premia were close to their post-Global Financial Crisis lows (Graph 9). Graph 9 And equity investors appeared to take out only modest extra downside insurance in response to the early
flurry of news about tariffs (Graph 10). Graph 10 There are several possible reasons for this apparently benign reaction. Investors may have believed tariff
threats were being used primarily as a negotiating tool, with relatively limited longer term economic
effects. They may have believed other promised US policy initiatives, including fiscal measures and
deregulation initiatives, would more than outweigh the impact on global activity. They may have believed
that demand in countries outside the US, including Australia, would be insulated by adjustments in
exchange rates ¹⁰ and extra stimulus in key overseas markets. Or they
may simply have believed that US policymakers would again show limited tolerance for declines in equity
prices, as happened in 2018/19 . That confidence has taken a bit of a knock in recent days. Some of that reflects recent US data, and some
evolution in the direction of tariff policy. But it may also reflect a growing recognition that, if
companies and households come to conclude that trade policy uncertainty has moved on from classical
Uncertainty (‘carry on till the fog lifts’) to genuine Ambiguity (‘almost anything could
happen’), they may choose to batten down the hatches – postponing planned spending,
particularly on longer term capital investment, until things become clearer. Such ‘watchful
waiting’ could prove rational individually, but economically damaging in aggregate. As The
Economist put it recently, ‘tariff uncertainty can be as ruinous as tariffs
themselves’. ¹¹ The Federal Reserve estimated that heightened
uncertainty over trade policy in 2018 reduced global GDP by nearly 1 per cent in 2019 ¹²
– and Graph 6 suggests the pick-up in policy uncertainty is much larger this time around. The
possibility of such an effect played a part in the Board’s policy deliberations in February. Key uncertainty 2: Capacity in the domestic economy A second key uncertainty lies closer to home, in the labour market. While the recent strength in
employment growth is welcome, it’s also unusual after a period of such subdued GDP growth. The
question is what it means for the margin of spare capacity in the economy, and hence for the inflation
outlook. Assessing this issue is harder than it seems. Spare capacity cannot be directly observed. And its
sustainable level has no set value, and likely changes over time as the structure of the economy evolves.
Some argue this makes the concept meaningless – but that does require you to have an alternative
narrative for inflation. At the RBA, we prefer to give it some weight while recognising the pervasive
uncertainties, by building up a picture using a wide range of qualitative and quantitative data, and
analytical techniques – as well as regularly challenging how we could be wrong. An obvious place to start when assessing labour market capacity is to look at proxy measures. Two of the
most important are unemployment (those looking for work) and underemployment (those in work, but looking
to do more hours). As recently as November, we were projecting unemployment to rise to
4¼ per cent by end-2024 and 4½ per cent in late 2025, as past weak activity reduced
hiring rates. In fact, unemployment has remained at or around 4 per cent, and underemployment
has fallen back to late-2022 levels. A range of other capacity measures have also stabilised or reversed
in recent months, including the ratio of vacancies to unemployment, and surveys of firms’ reported
labour constraints (Graph 11). Graph 11
With activity projected to pick up in 2025 as private demand recovers, these developments have caused us
to revise down our central projection for unemployment.
But the implications for inflationary pressure depend on where this leaves spare capacity relative to
sustainable levels. Two considerations suggest labour market conditions are relatively tight. First, all
of the measures in Graph 11 lie some distance above their historical averages – and
unemployment remains close to its lowest level at any time in the past 50 years. ¹³ But
that can’t be the end of the matter – because the levels of nominal and real wage inflation
associated with a given level of unemployment have fallen substantially over that period. So the
sustainable level must be lower too. ¹⁴ How much lower, no-one can say for
sure. But it is possible to back out a range of time-varying estimates from past relationships between
unemployment, wage and price inflation, using a suite of statistical methods of varying levels of
sophistication. These estimates include the immediate pre-pandemic period, when wage inflation
persistently undershot forecasts.
Those analytical approaches all suggest that, while sustainable unemployment levels are
likely to have fallen materially in recent decades, current labour market conditions still appear
relatively tight. Combined with the lower unemployment projection, that would suggest somewhat greater
upward pressure on inflation from the labour market over the medium term. Exercises using the other
measures in Graph 11 reach a similar conclusion. But these are critical judgments – and serious commentators from academia, the financial markets and
elsewhere have argued that we may be taking too pessimistic a view. We take those challenges seriously. Some point out that business surveys of employment intentions have been at, or slightly below, long-run
averages. And that is true, but such surveys typically focus on the market sector, where employment
growth has been relatively subdued. They tell us less about pressures in the non-market sector, which has
accounted for most of the recent strength in aggregate employment (Graph 12). Graph 12 That leads to a different challenge – that non-market employment has limited influence on aggregate
wage and inflation pressure, because it draws on a different labour pool. But it is hard to find support
for this in the data. For example, the health care sector – a big contributor to aggregate
employment in recent years – has drawn quite materially on workers in other industries
(Graph 13), helping to equalise cross-sectoral wage growth. ¹⁵ Discussion with liaison
contacts suggest similar mechanisms are at work in other sectors too, including construction. Graph 13 A third argument against the view that labour market conditions are relatively tight notes that nominal
wage growth has been easing (Graph 14). But with measured productivity growth as weak as it has been
recently, that still implies elevated growth in companies’ unit labour costs. Some of that apparent
strength could reflect under-measurement of productivity growth or a temporary burst of real wage
catch-up to past inflation, rather than labour market tightness. But such effects would need to be
unusually large to account for the whole of the gap. ¹⁶ Graph 14 Finally, it is possible that, over and above the impact of labour market conditions, recent disinflation
also reflects compression in other aggregate price drivers, including margins and housing costs. In that
context it is noteworthy that output-based measures of capacity pressures have continued to fall. Drawing this all together, our central projection reflects a judgement that labour market conditions will
remain relatively tight over the forecast period, and a little tighter than assumed in November. At the
same time, we have recognised the risk that recent inflation data may suggest we have overestimated the
extent of excess demand in the labour market by applying a little downwards judgement on the inflation
profile. And the Statement on Monetary Policy sets out what one would need to believe to
justify an even larger downward adjustment, as a risk scenario. ¹⁷ Implications for the RBA’s monetary policy decision Graph 15 compares the central projection for trimmed mean inflation in February with that in
November. Inflation is slightly lower in the near term, reflecting the downside news on inflation, wages
and activity. But it is a little higher further out, stabilising slightly above the midpoint of the
target range, reflecting the surprising strength in the labour market. Graph 15 Why then did the Board cut rates? Did we reject the staff forecasts, as some have claimed? Or did we
suddenly and confusingly relax our previously stated intolerance for persistent inflation deviations from
target? Nothing of the sort – for me at least, the rationale is relatively simple. First, the encouraging news on price and wage inflation gave us somewhat greater confidence that
underlying inflation is on track to return to the target range in the near term – if anything, a
little more rapidly than previously expected. The Board noted that the combination of lower inflation
data, and a lower near-term projection, put Australia in a very similar position to many other countries
ahead of their first cuts (Graph 16). Graph 16 Second, however, the Board also recognised that the uncertainties about the outlook for inflation become
larger, the further out you go. One uncertainty relates to future changes in the cash rate. All projections have to assume something about this path, and by convention we assume it follows market expectations. In
February, that curve implied up to four 25 basis points cuts over the forecast horizon, at a
somewhat more frontloaded pace than in November. In light of the data then available, including the
strong labour market, it was not clear that a rate cutting cycle of this depth was likely to
return underlying inflation sustainably to the midpoint of the target range. The February projections are
consistent with that view. Third, that did not, however, mean there was no case for a cut at all. To see that, the red swathe in
Graph 17 shows an illustrative range of projections for underlying inflation at the time of the
February forecast under the alternative assumption of an unchanged cash rate target of
4.35 per cent. Graph 17 The centre of the swathe lies slightly below the midpoint of the target range, consistent with a bias to
cut. But there were good arguments for both a hold and a cut – and the Board discussed them in some
detail, as the minutes released earlier this week show. ¹⁸ Foremost in that debate included the issues
I have discussed today – the outlook for global activity, and the degree of spare capacity in the
labour market. Some have flagged a concern that the Board’s messaging on rates feels like fine-tuning. It is
certainly true that the pervasive uncertainties we will face over the forecast period are orders of
magnitude larger than the sorts of differences to the target midpoint I’ve discussed here. But the Statement on the Conduct of Monetary Policy agreed between the Treasurer and the Board is
clear: we set monetary policy such that inflation is expected to return to the midpoint of the target
range. And we do that because it maximises the chances of inflation remaining sustainably in that range.
The rate cut in February reduces the risks of inflation undershooting that midpoint, but the Board does
not currently share the market’s confidence that a sequence of further cuts will be required. That assessment will of course evolve as time proceeds and further data help distinguish between
alternative narratives of the economy. Interest rates will go where they need to go to maximise the
chances of keeping inflation sustainably in the target band while helping to sustain full employment.
Progress towards that target has been good – but it is too soon to declare victory. Many households
and companies are continuing to struggle – and the Board will continue to take decisions, meeting
by meeting, in the interests of all Australians. In so doing, our goal is to remove inflation from the
list of things people have to worry about, leaving them free to focus on navigating an increasingly VUCA
world. Endnotes I am particularly grateful to Sue Black, Chris

merits of decision-making under uncertainty in the 1980s, of course. Indeed the RAND Corporation

sometimes compared with John Maynard Keynes’ hope that ‘economists could manage to get
themselves thought of as humble, competent people on a level with dentists’. As a relatively
recent arrival to Australia from the United Kingdom, I have discovered that dentistry is one of
the many areas where my new adopted home has a substantial comparative advantage: Crocombe LA, GC

not possibly say. ⁶ The name comes from the Chicago economist of the 1920–1930s , Frank Knight. See, for instance, Knight FH (1933), Risk, Uncertainty and Profit , 1st reprint edition, Houghton Mifflin Co, Boston; or
