Aleš Michl: Notes from the 2023 Jackson Hole Symposium
Notes by Mr Aleš Michl, Governor of the Czech National Bank, at "Structural Shifts in
the Global Economy", an economic policy symposium sponsored by the Federal
Reserve Bank of Kansas City, Jackson Hole, Wyoming, 26 August 2023.

My discussions with colleagues from the Fed, the ECB, the Bank of England and
the Reserve Bank of New Zealand confirmed me in the view that our models
should, like theirs, be audited and critically assessed. Each central bank should
start with itself. In the Czech Republic, we cannot repeat 2017, when the amount
of liquidity in the banking system was increased significantly in order to weaken
the koruna and trigger inflation. We need to do better than a high-inflation,
highdebt, low-growth world.
The Jackson Hole Symposium, organised by the Kansas City Fed since 1982,
confirmed that the CNB's monetary strategy over the last 12 months has been right and
is now delivering some results.
A year ago, the new CNB Bank Board was facing inflation of 18%, the highest level in
the country's history (leaving aside the transformation period of the early 1990s).
We chose the following strategy to fight inflation:
1. Rates stabilised at 7%. The expectation was that rates would stay higher for
longer than we had been used to in the previous ten years.
2. A new strong-koruna policy. The high prices of imported commodities needed to
be brought down. The strong koruna is also tightening monetary conditions for
large firms, which were previously unaffected by the CNB's high rates because
they were borrowing in euros.
The monetary conditions, which reflect interest rates and the exchange rate, have
therefore been at their tightest in 20 years in recent quarters.
Inflation has fallen from 18% in September 2022 to 8.8% in July of this year.
Core inflation has gone down from 14.7% to 6.8%.
This is not yet a victory. Inflation is still at an unacceptable level.
Most of my fellow central bank colleagues were saying much the same at the Jackson
Hole Symposium. This event is to economists what Cannes is to film-makers and
Davos is to the business community: the top table. Most of the world's central bank
governors are here. First to give a speech was Jerome Powell, Chair of the Fed's Board
of Governors (Powell, 2023). ECB President Christine Lagarde also spoke (Lagarde,
2023). Powell and Lagarde both affirmed their central banks' intention to fight inflation
and return it to the 2% target. Both indicated that this would involve keeping rates
higher for longer. No mention was made of cutting rates.
Along with governors' speeches, presentations of papers by prominent academics form
the backbone of the symposium. The theme this year was "Structural Shifts in the
Global Economy". If you read all these papers, you'll be reminded of how monetary
policies have gone from one extreme to the other in recent years: a long period of zero
interest rates and growing central bank balance sheets (I describe the negative
example of the Czech Republic in 2017 in Michl, 2023, and in the text below) was
replaced by a rapid rise in rates. The switch from extremely low to extremely high rates
has generated a variety of problems.
The first extreme was zero interest rates. They induced growth in private and public
debt. This issue was explored by Serkan Arslanalp (IMF) and Barry Eichengreen
(University of California, Berkeley) in their paper "Living with High Public Debt". The
main thesis in this paper is that the debts of advanced, emerging market and
developing economies are not going to decline significantly for the foreseeable future.
According to the authors, the world faces lower growth, ageing populations will
necessitate higher spending on healthcare and pensions, and politicians will be
unwilling to cut expenditure/debt for fear of losing elections. Liu et al. (2022) show that
near-zero rates trigger stronger investment by market leaders relative to market
followers. This increases their market power and leads to less competition. Aggregate
productivity in the economy is thus lower than when interest rates are at normal levels.
The other extreme was the sharp rise in rates that occurred, for example, in the Czech
Republic from 2021 until the first half of 2022. This revealed that the central bank had
let too much money get into the economy in the past. At the Jackson Hole Symposium,
Yueran Ma (Associate Professor, University of Chicago) and Kaspar Zimmermann
(Professor, University of Maryland) showed in their paper "Monetary Policy and
Innovation" that rapid and radical monetary policy tightening reduces investment in
innovation and hence lowers productivity in the economy and pushes up inflation in the
future. The authors' findings do not imply that monetary policy should be extremely
dovish. That would represent a return to the first extreme incentivising borrowing. Both
these extremes have perverse effects.
The impacts of the extreme policies and the parallel trends in the economy are
assessed by Duffie (2023) for the US financial market and, for example, by Grimm,
Laeven and Popov (2023) for the euro area. The impacts on global trade are
summarised by Alfaro and Chor (2023).
It would be inappropriate for me to evaluate the polices of other central banks, but it
would be a mistake not to critique the past policy of the CNB. The main problem in the
Czech Republic was the rapid switch from one extreme to the other - from ultra-low
rates and efforts to trigger inflation to ultra-high rates and efforts to rein inflation back in
again. Everything comes at a cost. A rapid increase in rates doesn't always mean lower
inflation in the future. You can't put right the mistakes made in past years in one fell
swoop. This is discussed in the classical literature - see, for example, Friedman (1968)
and Lucas (1976).
The big lesson for me is that we will try not to repeat 2017 at the CNB. The
interventions made at that time to weaken the koruna and raise inflation led within four
months to an increase in the CNB's balance sheet, or rather in the banking sector's
liquidity. It increased from CZK 1,300 billion in December 2016 to CZK 2,300 billion in
April 2017. This contributed to us later having the highest core inflation in the EU. Each
central bank should start with itself, with self-reflection. My discussions with colleagues
from the Fed, the ECB, the Bank of England and the Reserve Bank of New Zealand
confirmed me in the view that our models, should, like theirs, be audited and critically
assessed.
Professor at the University of Chicago and former Governor of the Reserve Bank of
India Raghuram Rajan (Rajan, 2023) said: "Central banks have constrained their own
policy space with asymmetric and unconventional policies, ostensibly intended to deal
with the policy rate touching the lower bound. They have triggered a variety of
imbalances that are making fighting inflation harder today." More purposeful and less
interventionist central banks would probably do better than a high-inflation, high-debt,
low-growth world.
The CNB Bank Board's policy goal is to achieve low inflation in 2024. This is our job. It's
what we are going to try to do for the Czech Republic and what I pledged to deliver
within two years when I was appointed governor (Michl, 2022a). Fiscal policy could be a
big help if the government deficit were to fall in 2023 relative to 2022 and in 2024
relative to 2023 - see, for example, Cochrane (2023) and my notes from Jackson Hole
last year (Michl, 2022b, 2022c, 2022d).
The symposium took place on 24-26 August 2023 in Jackson Hole, Wyoming, USA.
