Speech
Report from Norges Bank Watch 2024

Remarks by Pal Longva, Deputy Governor of Norges Bank, 23 February 2024.

In February/March each year, the Centre for Monetary Economics (CME) presents a
report commissioned by the Ministry of Finance on Norges Bank's activities. A
committee of independent economists assesses Norges Bank's conduct of monetary
policy. The reports are published by the CME in its Norges Bank Watch Report Series.

First, I would like to thank this year's committee for an excellent and thorough report.
An annual assessment of this kind is very useful. I would also like to thank the Centre
for Monetary Economics for hosting the event and for the opportunity to comment on
the report.

I would like to comment on four major topics raised by the committee: the conduct of
monetary policy in 2023, modelling the krone exchange rate, taking account of
international impulses and communicating uncertainty.

Let me begin with the conduct of monetary policy last year.

The year 2023 was marked by continued high inflation both in Norway and among its
trading partners. At the beginning of that year, we expected a policy rate of around 3
percent in 2023. That didn't happen. We revised our economic growth and inflation
forecasts, and the policy rate was raised higher and faster than we had anticipated.

Norges Bank Watch's analyses indicate that the policy rate should have been raised
faster. When we set the policy rate, we must rely on the information available and our
best assessment of the outlook and balance of risks. There was considerable
uncertainty about the outlook for the Norwegian economy and about how high the
policy rate needed to be to bring inflation back to target within a reasonable time
horizon. Monetary policy trade-offs were challenging. The Monetary Policy and
Financial Stability Committee was concerned with balancing the risk of tightening too
much against the risk of tightening too little. If the policy rate was raised too little,
inflation could remain high for along time, in which case it could prove more costly to
bring inflation down again later. On the other hand, a policy rate that was too high could
contribute to a more pronounced slowdown in the Norwegian economy than
necessary. This is a situation we wished to avoid.

We are committed to communicating our monetary policy decisions clearly and
effectively. We are therefore pleased that Norges Bank Watch is of the opinion that our
communication is effective and our response pattern is well-understood by the
market.

Let me now say a few words about the krone exchange rate, which is a key topic in the
report.

The krone depreciated through 2023, especially in the first half of the year. This
surprised many observers, Norges Bank included. Norges Bank Watch presents a
model that forecasts a significant depreciation last year. The forecast depreciation is
steeper than was actually the case, but the model more accurately forecast exchange
rate movements than we did.

Norges Bank Watch interprets the model results to mean that more long-term factors,
such as price level differences between Norway and other countries, may have played
amore important role for the krone exchange rate than assumed in our projections. At
the same time, the report shows that the exchange rate projections are very sensitive
to the long-run trend assumed for the exchange rate. Under a different assumption for
this trend, the exchange rate more closely follows Norges Bank's projections. It is
challenging to forecast exchange rates and difficult to determine which model is best.

There are many factors that can influence the krone exchange rate that we can neither
foresee nor do anything about. Monetary policy influences the krone exchange rate
through policy rate setting, but what central banks in other countries do is also
important. Through the first half of last year, the interest rate differential against our
main trading partners fell and eventually became markedly negative. The decline in the
interest rate differential coincided with a krone depreciation.

Our projection for the krone exchange rate will normally change relatively little over the
forecast horizon from its recent level. Over time, we believe that this approach will give
us the best forecasts and the best basis for making the right trade-offs in the conduct
of monetary policy.

A third topic that is mentioned is how we respond to what is happening internationally.

Norges Bank Watch questions whether we could have been quicker to capture
international impulses. Over time, there has been an evolution in this area at Norges
Bank. The Norwegian economy has been hit by large international shocks in recent
years. In the wake of the pandemic and subsequently as a consequence of Russia's
invasion of Ukraine, there was a surge in freight rates and many commodity prices. It
became important for us to improve our understanding of how international price
impulses affect domestic prices.

We have long had an indicator of price developments for imported consumer goods.[1]
In recent years, we have looked more closely at how international price impulses affect
domestic inflation. The chart shows an indicator that we have constructed to capture
developments in prices for imported intermediate and capital goods.[2] The indicator
appears to influence inflation with a marked lag. This gives us a better overview of
price changes at early stages of the value chain and enables us to capture changes in
price impulses more quickly. This may lead to better projections for overall consumer
price inflation in Norway.

We are continuing our work to improve our analyses, so that we can capture relevant
information from other countries more quickly.

The last topic I would like to comment on is communicating uncertainty.

As Norges Bank Watch points out, macroeconomic forecasts are associated with
considerable uncertainty. We may perhaps be able to quantify some of this
uncertainty, but other types of uncertainty are difficult or impossible to measure.
Examples of the latter may be the economic consequences of pandemics, war, climate
change and technological innovation.

Prior to the pandemic, we used fan charts for our projections. Such fan charts can
illustrate the uncertainty surrounding projections based on historical forecast errors.
When the pandemic hit, it became obvious that these fan charts did not adequately
express uncertainty ahead. This illustrates a challenge posed by probability bands.
They may give the impression that we are able to quantify uncertainty that in reality
cannot be measured. Symmetrical fan charts in particular, which we used previously,
may be misleading. The type of asymmetrical fan charts that Norges Bank Watch
proposes is better. In our most recent monetary policy reports we have illustrated
uncertainty surrounding some key projections. We use a method that also allows
uncertainty to be asymmetrical and vary over time. This is useful. At the same time,
these estimates do not take into account all possible outcomes either.

An alternative is to develop conceivable scenarios. These may illustrate how possible
shocks might affect the economy. At the same time, such scenarios do not always hit

the mark.

The Monetary Policy and Financial Stability Committee devotes considerable time to
discussing the risks around our forecasts. In our monetary policy reports we seek to
communicate the risk factors the Committee has given weight to. At the same time, we
agree with Norges Bank Watch that this part of our communication can be developed
further. Going forward, we will seek to express our assessments of various risk factors
better.

Let me conclude by again thanking Norges Bank Watch for an excellent report. These
annual evaluations are very useful for us and make an important contribution to our
work to improve our analyses and communication.

Thank you for your attention!
