Christine Lagarde: Central bank independence in an era of volatility
Lamfalussy Lecture by Christine Lagarde, President of the ECB, at the
Lamfalussy Lectures Conference organised by the Magyar Nemzeti Bank,
pre-recorded in Frankfurt am Main on 15 January 2025Budapest, 27

In his later years, Alexandre Lamfalussy was once
asked what his fundamental motivation in life was. He recalled the
experience of his turbulent youth, surrounded by the destruction
caused by the Second World War. [1] “In the aftermath of the war,”
Lamfalussy said, “I decided to serve the community in the rebuilding
of Europe. ”[2]
He went on to do just that. A member of the
Delors Committee and the first President of the European Monetary
Institute, Lamfalussy helped pave the way for Europe’s monetary union
and the establishment of the ECB.
His generation had also been
scarred by the difficulties of the “Great Inflation” in the 1970s. [3]
And so Lamfalussy – alongside other architects of the euro[4] –
ensured that the ECB would have sufficient powers to prevent a
scenario where inflationary expectations once again became embedded in
the economy.
We can see proof of this today, as advanced
economies emerge from the largest inflation shock in a generation.
As in the 1970s, a series of shocks contributed to high and
persistent inflation. But unlike the 1970s, inflation has since fallen
relatively fast across advanced economies – and expectations have
remained firmly anchored throughout.
This hard-won progress
has been in large part due to the independence of central banks, which
has given them the ability to take difficult but necessary monetary
policy decisions in pursuit of stable prices. The rise of central bank
independence
In the late twentieth century, central bank
independence spread rapidly around the world.
A strong social
consensus about its benefits – emerging from the negative experience
of the 1970s – sparked what Lamfalussy would later call a “sea change”
in monetary policymaking. [5]
By one account, over 80% of the
world’s central banks became operationally independent by the turn of
the millennium. [6] And price stability had been adopted as the
primary objective of monetary policy frameworks across almost all
advanced economies and many emerging market economies. [7]
Moreover, independent central banks both contributed to – and
benefited from – a period of low macroeconomic volatility.
In
their famous paper, Alesina and Summers found a positive relationship
between the degree of independence of central banks and lower and less
volatile inflation outcomes. [8] At the same time, substantial
structural changes were afoot in the global economy, which also helped
to reduce macroeconomic volatility – an era that soon came to be known
as the Great Moderation. [9]
Globalisation led to an enormous
increase in both global labour supply and production capacity, which
meant that prices and wages were often little affected even in the
face of strong demand. And the oil crises of the 1970s had sparked a
wave of change in global energy markets, resulting in a more elastic
energy supply.
The upshot of the Great Moderation was a
virtuous circle.
An environment of low macroeconomic
volatility made it easier for independent central banks to deliver on
their price stability mandates. That, in turn, solidified the social
consensus in support of central bank independence and helped ensure
its growing adoption around the world – further contributing to
lowering levels of volatility. The era of volatility
The end of
the Great Moderation came suddenly and unexpectedly in 2008 with the
arrival of the global financial crisis. And over the last years in
particular, our world has changed dramatically.
Indeed, the
two forces that fostered the spread of central bank independence – a
strong social consensus and growing pools of global supply – are now
coming under increasing pressure.
While recent research
suggests that de jure central bank independence has never been more
prevalent than it is today[10], there is no doubt that the de facto
independence of central banks is being called into question in several
parts of the world.
One study examining 118 central banks in
the 2010s shows that around 10% of them faced political pressure in an
average year – even those central banks with a high degree of de jure
independence. [11] Another paper finds that between 2018 and 2020
alone, de facto central bank independence deteriorated for almost half
of those central banks in jurisdictions accounting for 75% of global
GDP. [12]
There is evidence to suggest that political influence
on central bank decisions can also contribute substantially to
macroeconomic volatility. For instance, persistent political pressure
on a central bank has been found to affect the level and the
volatility of exchange rates, bond yields and the risk premium. [13]
At the same time, geopolitical tensions threaten to amplify
volatility by increasing the frequency of shocks hitting the global
economy.
We have already seen the impact of geopolitical
tensions play out in Europe. Following Russia’s invasion of Ukraine in
early 2022, average output growth volatility in the euro area surged
by 60% compared with before the global financial crisis, while average
inflation volatility shot up by 280%. [14]
An environment of
heightened volatility could make the task of maintaining price
stability more difficult to achieve. [15] This could raise concerns
that independent central banks are failing to deliver on their
mandates, which could undermine the social consensus and further
amplify volatility in the economy.
So, the question that comes
to the fore is: will the current era of volatility turn the virtuous
circle that facilitated the rise of central bank independence into a
vicious circle that leads to it being undermined?The benefits of
central bank independence in today’s world
All things
considered, I would argue that this is unlikely to happen.
A
volatile macroeconomic environment actually makes the benefits of
central bank independence all the greater. We saw this during the
recent inflation shock.
In OECD countries, average annual
inflation surged to 9. 6% in 2022 as they faced a variety of shocks
that compounded each other. [16] In response, independent central
banks sharply increased policy rates.
These actions led to a
rapid decline and convergence in the respective inflation paths of
major economies – despite all these economies facing different shocks.
Moreover, inflation expectations have remained firmly anchored,
suggesting that the public continues to have faith in independent
central banks’ commitment to price stability over the long run.
[17]
In today’s world, central bank independence offers two key
advantages.
First, it acts as a headwind to volatility in
these unpredictable times.
As we emerge from a period of very
high inflation, the issue of time inconsistency is more relevant than
ever. [18] Compared with the pre-pandemic era of low inflation,
central banks may need to contend with lower levels of rational
inattention. [19]
In this environment, credible policy regimes
become even more important for maintaining trust in central banks.
Research finds that higher trust in the ECB lowers inflation
expectations on average and significantly reduces uncertainty about
future inflation. [20]
Second, central bank independence also
contributes to regional strength in a world increasingly defined by
geopolitical rivalries.
Price stability provides the
foundation upon which other strategic goals can be achieved. Regions
with stable prices tend to have more efficient resource allocation and
higher levels of competitiveness, and they attract greater levels of
investment. At heart, strong economic institutions are the fundamental
cause of long-run economic growth and development differences between
regions. [21]Conclusion
Lamfalussy once described the task of
launching the euro as “navigating in uncharted waters”. [22] In an era
of volatility, independent central banks now also find themselves in
unfamiliar waters.
While inflation has fallen sharply, central
banks are still likely to face a more volatile macroeconomic
environment compared with the Great Moderation.
It therefore
remains imperative that central banks have the independence to fully
deliver on their price stability mandates.
Thank you.
