Monetary policy in a shifting landscape

Inaugural Conference of the Research Network
on 'Challenges for Monetary Policy Transmission in a Changing World' (ChaMP)*

Dinner speech by Fabio Panetta
Governor of the Bank of Italy

Frankfurt, 25 April 2024

First of all, I wish to thank the organizers for inviting me. It is a great pleasure to be back
at the ECB, although it feels strange to be here as a guest.

Our vision of how the economy works is in perpetual motion. In 1949, Bill Phillips unveiled
the 'Phillips Machine'.' This ingenious contraption used water to represent money flowing
through the economy, with valves that could be opened or closed to simulate the effects
of policy interventions on consumption and investment. The economy was presented as a
fixed and deterministic system of relations that could be investigated until its functioning
became clear once and for all."

We know that, for better or for worse, the real world is very different. Indeed, if economic
relations were fixed and deterministic, our jobs would be easy but boring. Economic
relations are not fixed because the economy evolves following slow-moving structural
trends. And they are not deterministic, because there are many events that we tend to
conceptualize as 'shocks' - perhaps due to the limitations of our knowledge. The last four
years have been exceptional in this regard: from the Covid pandemic onwards, we have
witnessed a combination of shocks and structural changes with few historical precedents.

The global landscape has changed radically as a result, with important implications for
both the theory and the practice of monetary policy. A constructive interaction between
policy and research is key: at times like this, the dialogue between researchers and policy
makers becomes critical. Your job within the ChaMP Network is to help us improve our
understanding of the economy and the monetary policy transmission mechanism.

I would like to thank Piergiorgio Alessandri, Margherita Bottero, Antonio Conti, Francesco Corsello,
Stefano Neri and Eliana Viviano for their contributions.

The machine was also known as the Monetary National Income Analogue Computer, or MONIAC.
Phillips found that, even in his stylized setup, policy interventions based on feedback rules could be

highly sensitive to lags, delays and over or undershooting issues. See 'MONIAC: Phillips Monetary
National Income Analogue Computing Machine', special issue of Economia Politica, December 2011.

My remarks this evening have two objectives. First I will revisit the story of 2021-2023,
taking stock of where the events have taken us. Then I will discuss the implications of the
current outlook for the monetary policy stance of the ECB.

My intention of course is to flesh out puzzles and questions, not to lecture you, or indeed
hand out prescriptions as to what the ECB or other central banks around the world should
do next. Yet the picture that has emerged from the data has important implications for
the ECB's next steps.

1. Lessons from the 2022-2023 tightening cycle

Let me start by reviewing the main lessons from the tightening cycle of the last two years.

We have been hit by large supply shocks while undergoing a structural shift away from
globalization

The lockdowns that came with the Covid pandemic hit firms' activities and households'
income prospects at the same time, affecting both the demand and supply of goods and
raising the spectre of a prolonged economic depression.? The interplay between demand
and supply also played a key role in the subsequent recovery. At the end of the pandemic,
consumption increased as citizens regained confidence and resumed their pre-pandemic
routines. However, this demand boost took place at a time when supply disruptions had not
yet been resolved, exacerbating bottlenecks and putting further pressure on global supply
chains (Figure A1).4 Production cuts by oil exporting countries and jumps in gas prices
pushed up inflation (Figure A2). Prices rose dramatically for a range of goods, including food
and agricultural products. The Russian aggression against Ukraine greatly magnified these
shocks, pushing up energy and food prices and adding to the general uncertainty about
the outlook. What had started as an ambiguous combination of demand- and supply-side
factors rapidly evolved into a situation dominated by imported supply-side shocks.

The Russia-Ukraine war was in itself unpredictable, but it erupted - and it keeps unfolding -
against a background of increasing geopolitical disputes. The world has recently
experienced a series of major setbacks to geopolitical stability, with a number of violent
conflicts that sets a tragic record in the post-World War II era.> Globalization has slowed
as a result. We are now moving towards a fragmented global landscape characterized by
rising protectionism and volatile trade flows. This shift has important long-run implications,

The pandemic called into question the very difference between demand and supply shocks: sometimes,
adverse supply shocks give place to demand shortages, pushing economic activity below its potential. See
V. Guerrieri, G. Lorenzoni, L. Strauband and I. Werning, 2022, 'Macroeconomic Implications of COVID-19:
Can Negative Supply Shocks Cause Demand Shortages?', American Economic Review, 112 (5), 1437-74.

but it also matters in the short-run (and hence for monetary policy) because it affects
firms' profitability, riskiness and investment plans.

Of course, I am deliberately painting a broad picture of global developments. As you know,
there are important differences in the way the story unfolded in Europe and in the US.

The US experienced a much larger fiscal expansion, and - being a net exporter of food and
energy - was less affected by volatility in commodity prices. In the euro area, by contrast,
shocks to energy supplies had a strong impact on both income and production. This
means that the euro area saw a relatively larger share of inflation of the 'bad' type, which
is typically more problematic for monetary authorities.®

The exposure of the euro area to foreign shocks is largely due to two structural features.
One is the well-known scarcity of natural resources - and hence a high dependence on
energy imports, especially Russian gas. The other one is the historical reliance on an
'open economy' model where growth depends heavily on foreign demand and trade
openness. These features may also play a role during the green transition, because the
production and storage of renewable energy relies on rare materials that, like oil and gas,
Europe needs to import from abroad.

How did the ECB manage all this? Taking decisions in real time was tricky ...

The ECB responded to the rise in inflation with an unprecedented sequence of interest
rate hikes.

Calibrating the interventions in real time was truly challenging. As you know all too well,
distinguishing between demand and supply shocks is never easy, and became more
difficult in the pandemic era. This identification problem becomes even harder when
prices are affected by a combination of many different shocks. Furthermore, getting the
identification right is not enough: you also need to form a view on how the shocks
propagate through the economy. This is not trivial if you are dealing with events that
have not been seen for decades - like a war on your doorstep - and markets with very
peculiar structural features - such as the natural gas market.'

In previous speeches I distinguished between good, bad and ugly inflation. 'Good' inflation is driven by
buoyant domestic demand and a wage growth consistent with the target; monetary policy should nurture
it until the target is reached. 'Bad' inflation reflects negative supply shocks that raise prices and depress
economic activity; monetary policy should look through it. 'Ugly' inflation is driven by a de-anchoring of
inflation expectations; monetary policy should immediately stamp it out. F. Panetta, 'Patient monetary
policy amid a rocky recovery', speech delivered at Sciences Po, Paris, 24 November 2021.

Wholesale gas prices are sticky because trading is often based on long-term contracts indexed to past
prices. Furthermore, retail prices adjust slowly to changes in wholesale prices due to regulatory frictions.
In the oil market, trading is instead based on spot contracts, and retail (gasoline) prices closely track
wholesale prices. As a result, oil shocks have a large impact on consumer prices in the short run, whereas
gas shocks cause a slow, persistent increase in inflation with peak responses that can take place almost
two years after the shock (see P. Alessandri and A. Gazzani, 'Natural gas and the macroeconomy: not
all energy shocks are alike', Banca d'Italia, Temi di Discussione (Working Papers) 1428, 2023). After the
invasion of Ukraine, energy markets were also heavily influenced by strategic supply manipulations
enacted by Russian producers.

With the luxury of hindsight, we can now read the macro outlook more accurately.

Consider for instance the discrepancies between the macroeconomic data observed in
2021-2023 and the official forecasts formulated by central banks one year in advance
(a statistic to which the media paid a lot of attention both in Europe and in the US°). In
its one-year ahead forecasts, the ECB was surprised on the upside by both inflation and
GDP growth in Q2 and Q3 2021, presumably because of the unexpected demand boost
associated to the re-opening. After that, it systematically observed positive surprises for
inflation and negative surprises for GDP growth until Q3 2023 (Figure 1).

This pattern corroborates the view that adverse supply shocks, which push prices and
quantities in opposite directions, played a key role in causing the rise in inflation?

The credit market -- a good barometer of the business cycle in the euro area - reinforces
the view that the corporate sector was not faring too well. Credit demand declined
steadily since the end of 2022, especially for the loans that firms use to finance fixed
investments.'? But geopolitical shocks and high energy prices also reduced firms' revenues
and increased their riskiness, contributing to a stronger-than-expected contraction in the
supply of bank credit (Figure A3)."'

With potentially important implications for productivity: more on this below.

2023, see P.R. Lane, 'Inflation and monetary policy', presentation delivered at the Policy Lecture at
Aix-Marseille School of Economics (AMSE), Marseille, 22 March 2024.

In short, the catch-up in demand stemming from the post-Covid recovery was
compounded by an unlucky sequence of large and previously unseen supply shocks. All
in all, supply shocks may have had a more significant impact on prices and economic
activity than demand shocks.'*

... but the key priority was clear: to put a lid on inflation

Does this mean that the Governing Council overlooked supply-side dynamics and got
its policy choices wrong? This conclusion may be tempting for critics, but it would be
unjustified for two reasons.

In mid-2022, the key ECB interest rates were still negative: a recalibration of the stance
was clearly needed. Furthermore, the rise in inflation came at a time of tight labour
markets, raising serious concerns that a wage-price spiral (and potentially a de-anchoring
of inflation expectations) could follow. This is a risk that no central bank can take, nor
downplay on the basis of flimsy separations of demand and supply shocks. As of 2022,
the priority for the ECB was to bring inflation down, keep long-term inflation expectations
anchored and preserve its own credibility. A bold response to the price pressures achieved
all three objectives.

2. Where do we stand?

The macro outlook has changed, and risks from wages are decreasing

It is clear that the situation has changed substantially over time. Core inflation has
been falling steadily since July 2023, while GDP growth has been hovering around zero.
Furthermore, in the last quarter of 2023 both inflation and GDP growth surprised to the
downside. This indicates that, while supply shocks and energy prices receded, aggregate
demand also weakened, partly in response to the monetary restriction.

Inflation expectations are well-anchored and the probability of a self-sustained inflationary
spiral is low. Labour market data suggest that wage growth may have peaked in 2023
and is evolving in line with our projections, which foresee a return to our target in 2025.3

More importantly, discussing wages in isolation can be very misleading: we need to
consider wages along with other input costs, profits and productivity too. With this in
mind, we can identify three hypothetical scenarios where wages grow without creating
inflationary pressures.

Q4 2023.

First, the wage rise could take place in a context where firms' total production costs
(of which wages are only one component) decline or remain constant. Firms price their
goods by applying markups to total costs rather than solely to wages. Consequently,
if the costs of other inputs drop, wages can, in principle, rise without affecting
prices. After the sharp acceleration observed in 2022, total costs have decelerated
and they are now growing at a rate that is consistent with the pre-pandemic norm
(Figure 2).'4 This is indeed the reason why the acceleration in wages did not prevent
a decline in inflation in 2023.

Second, firms may absorb the rise in wages (and potentially even in total costs) by
reducing their profit buffers. This compensation requires a temporary compression in
firms' profit margins and, as such, it is more likely to take place when demand is weak
and margins are high. This is currently the case in the euro area."®

Third, the rise in wages could be accompanied by a rise in productivity. An improvement
in productivity raises the workers' output, implying that unit labour cost (the ratio of
hourly compensation to hourly output) can remain constant or even decline despite a

See Panetta, F., 'Economic developments and monetary policy in the euro area', speech delivered at
the 30 ASSIOM FOREX Congress, Genoa, 10 February 2024. According to Banca d'Italia estimates,
labour contributes less than other production inputs to total costs; considering only the direct
shares of labour and intermediate inputs, labour accounts for around 40 per cent of the total.
Impulse-responses from a quarterly VAR model indicate that shocks to energy prices have a large
and quick impact on producer price inflation (PPI) for intermediate goods, and are then gradually
and only partially transmitted to consumer good PPI, core consumer price inflation (CPI) and wages.
Wages peak over a year after the shock, with a maximum response that is one order of magnitude
smaller than the shock itself (about 0.3 percentage points for a hypothetical 5 per cent increase in
energy prices).

In 2023 mark-ups in the three largest euro area countries were around 1.5 percentage points higher
than in 2022 on average.

higher wage bill. This mechanism is likely to play a role as well. Productivity declined in
2022-2023, but the decline was partly due to divergences among the prices of different
production inputs: faced with extremely high energy costs, firms had a clear economic
incentive to use more labour in production, which in turn led to a decline in output per
worker. The drop in productivity might be naturally reabsorbed over time, as the relative
costs of labour and non-labour inputs and the capital to labour ratio revert to their
long-run levels.

Looking beyond the near term, I would also emphasize that productivity hinges critically
on the capital stock. Firms should invest more in order for workers to become more
productive. This is clearly a complex theme that goes beyond the remit of central banks.
And I do not necessarily subscribe to the (fascinating) view that monetary policy can
affect capital stocks and productivity into the distant future.'® However, hesitations in
adjusting interest rates to the fall in inflation would discourage firms from investing,
delaying the expansion of the capital stock, hampering productivity and generating a
competitive disadvantage for the euro area in global markets.

The 'balance of risks' looks very different now

Not surprisingly, the risks surrounding the macroeconomic outlook have also changed
under the combined influence of these factors. According to the ECB Survey of
Professional Forecasters, the upside risks for inflation that dominated in 2022-2023 have
receded, leaving the uncertainty around price dynamics roughly balanced, while the risks
for economic activity remain tilted to the downside (Figure A4).

There are two reasons why mitigating these downside risks is important.

The first one is that the interest rate hikes implemented thus far will keep biting well into
2024. Estimates by Banca d'Italia staff suggest that their impact on inflation will actually
be greater in 2024 than it was in 2023, with a non-negligible contribution provided by
the bank lending channel (Figure A5).

The second one is that the ECB is also shrinking its balance sheets, and it is doing so
faster than most other central banks. We have relatively little evidence on the relationship
between the availability of central bank liquidity and credit conditions. This is a theme
that deserves more research in the future, also in light of the planned reduction in excess
liquidity. In any case, the responses to the Bank Lending Survey (BLS) suggest that,
inasmuch as QE provided a positive boost until 2022, the reduction of the Eurosystem's
balance sheet - even at this early stage - may exert a negative influence on the liquidity
position and lending volumes of euro-area banks (Figure A6). The figures are small, and
they come with the usual caveats attached to survey data, but they point to another
potential brake on economic activity.

Bureau of Economic Research WP 26666, 2020.

3. (Re)calibrating the monetary stance

From now on, we must weigh the risk of monetary policy becoming too tight ...

With inflation progressively moving towards our target, the question arises of what
the ECB should do next. The emergence of downside risks to the outlook implies
that the ECB should consider the possibility that monetary policy could become 'too
tight' going forward. Monetary policy is obviously too tight if it ends up causing a
deep recession, but it is also too tight if it pushes inflation below target and causes a
prolonged economic stagnation. We are reasonably far from the first scenario, but we
cannot (yet) rule out the second one.

In the United States, GDP and consumption have converged back to their pre-pandemic
long-term growth paths; in the euro area, they are still well below trend (Figure 3).
Furthermore, in its most recent projections, the International Monetary Fund (IMF)
predicts the US to grow over thrice as much as the euro area in 2024 (2.7 per cent versus
0.8 per cent).'7 Monetary policy is certainly not the only or even the main cause of this
divergence, but it is important that it does not become an unnecessary obstacle that
prevents the euro area from achieving its full potential. Combined with weak business
dynamism and relentless competitive pressures from abroad, a tight monetary stance
could generate hysteresis effects that would increase the risk of a protracted period of
economic weakness.

v7 IMF, World Economic Outlook, April 2024.

Looking back, the Great Recession and the sovereign debt crises caused a long period
of too low inflation (Figure A7) and a downward de-anchoring of long-term inflation
expectations (Figure A8).'® For years the ECB spent most of its energies trying to lift the
euro area out of that equilibrium. Inflation expectations are not a problem today, but that
experience demonstrates that letting inflation slip below the 2 per cent target could be
very costly. It would also be inconsistent with the symmetrical nature of the price stability
target enshrined in the latest Strategy Review (and could potentially undermine it).

... and assess our policy options accordingly: what goes up must come down'®

It is of paramount importance to act in a timely manner to minimize these risks. In my
view the ECB's action should be guided by three considerations.

First, we should think about the big picture surrounding decisions on interest rates.
Central banks do not act in a vacuum: they have to take into account a large number of
exogenous factors that interfere with the transmission of monetary policy and/or have
an independent (and potentially large) impact on prices and economic activity. As of
today, the big picture includes modest growth prospects at global level and high political
uncertainty. In Europe, it also includes a more restrictive fiscal stance*° and a run-down of
central bank balance sheets - a policy mix that is unlikely to support aggregate demand.

Second, inaction is not neutral. Based on current expectations, the ECB stance is likely to
remain restrictive - with real rates above their 'natural' level - well into 2025 (Figure AQ).
Keeping in mind the 'long and variable lags' in the transmission mechanism, this state
of affairs clearly calls for timely action: steering monetary policy is like steering a tanker,
and if the helmsman (or helmswoman) does not act well in advance, they will crash into
the harbour altogether. As I said, unnecessary delays may take us uncomfortably close
to the effective lower bound at a later stage if stagnation is entrenched and inflation
expectations fall below target.

Third, gradualism is important. Timely action would allow the ECB to be nimble and move
in small, progressive steps. Small rate cuts would counter weak demand, and could be
paused at no cost if upside shocks to inflation were to materialize along the way. They
would also minimize the likelihood of the ECB falling behind the curve and having to
hastily resort to larger rate cuts in the future. There are many reasons why large cuts

Journal of Political Economy, 69, 102031.

This popular expression is sometimes attributed to Sir lsaac Newton. The attribution is, in all likelihood,
apocryphal, but the question of whether interest rates can defy Newton's law of gravitation is valid all
the same.

20 In the last Macroeconomic Projection Exercise, the cyclically-adjusted primary balance of the euro area

is expected to increase from -1.5 per cent in 2023 to -0.7 per cent in 2025. The new fiscal framework
may generate a further tightening of the stance in the medium term.

are generally unpalatable.2' One of them is that they could create a credibility issue,
especially after an unprecedented tightening cycle.

An important question that has recently come up in the debate is to what extent the
ECB's decisions should be linked to the course followed by the Fed. The ECB's mandate
is to pursue price stability in the euro area, and the ECB's actions are not conditioned by
developments in other jurisdictions. However, US monetary policy has powerful spillovers
in the rest of the world, including the euro area." A failure to account for these spillovers
could lead to an inaccurate calibration of policy interventions."

I do not see this hypothetical 'decoupling' between the Fed and the ECB as particularly
critical at the current juncture.

The ECB's projections always take into account the expected path of interest rates in
the US and beyond. Governing Council members evaluate their policy options using
GDP and inflation forecasts that - to the best of their knowledge (or rather the staff's
knowledge) - already account for the influence of the Fed's decisions on the euro area.
The Fed's strategy is just one of the factors that must be reflected in the projections,
although it is certainly an important one.

Unexpected changes in the Fed's stance cannot by definition be included in the forecasts.
But, if anything, they are likely to reinforce the case for a rate cut rather than weakening it.
If markets expect interest rates to drop but the Fed keeps them unchanged (for instance
on the back of strong inflation data), the rest of the world faces an unexpected monetary
tightening. And a tightening in the US has a negative impact on inflation and output
in the euro zone." The reason is that - besides a depreciation of the euro (which is the
obvious, textbook type of effect) - the shock also causes a decline in global demand
and a tightening in financial conditions. Historically, the latter channels have been
quantitatively dominant, implying that the net impact of a spillover in the medium term
is both recessionary and deflationary.

4. Conclusions

The last two years have been tough for policy, but inspiring for research: it is not common
to witness geopolitical shifts, a 1970s-style energy crisis, large swings in inflation and a
record monetary tightening cycle in the space of 24 months. It may not be over yet.
After the direct confrontation between Israel and Iran over the past few weeks, another
worrying historical development, political tensions in the Middle East are bound to
remain high.

Being on the policy side of this trench, I hope that researchers will make the most of
this experience. You should dissect these complex events and turn them into a new
and better understanding of how the economy works. I suspect this process will take us
farther away from the 'Phillips Machine'. In any case, it should provide us with notions
and tools that can be deployed in the not-too-distant future to render monetary policy
more effective.

I hope my remarks tonight have given you an idea of some of the issues that sit at the
top of the priority list for me, and presumably for many of my colleagues within the ESCB.

Thank you for your attention and enjoy the rest of the evening.
