## Kerstin af Jochnick: Unusual measures in unusual times - experiences with the Riksbank's unconventional monetary policySpeech by Ms Kerstin af Jochnick, First Deputy Governor of the Sveriges Riksbank, to SACO (Swedish Confederation of Professional Associations), Stockholm, 29 January 2016.*

*

*Accompanying charts can be found at the end of the speech.I would like to thank Carl-Johan Belfrage, Hanna Köhler and Cecilia Roos-Isaksson for helping me with this speech.The start of a new year - particularly after such an eventful year as 2015 - can be a good time to look back and try to learn a few lessons from the past year's experiences.

I will therefore focus today on the reasons for the new monetary policy ground broken by the Riksbank in 2015.

This includes our introduction of a negative repo rate and our initiation of government bond purchases as a complement to repo rate cuts to further boost demand in the economy and increase inflation.The inflation target is worth defending.

This is why we have taken to unusual measures under unusual circumstances and these measures seem to have contributed towards good growth and a rising inflation trend.

At the same time, there is reason to remember that the low level of interest rates is leading housing prices and mortgages to develop in a dangerous direction.

I also intend to present a few preliminary reflections on the recently published assessment of the Riksbank's monetary policy.

## Why is the inflation target so important?Understanding the Riksbank's actions first requires understanding why we think the inflation target is so important.

We introduced inflation targeting in Sweden in 1993 after we were forced to

abandon

the

fixed

exchange

rate

regime.

We

used

academic

research

to

support

this decision, along with the good example provided by forerunners such as Canada and New Zealand. 1

A well-implemented inflationary targeting policy benefits economic development by making

inflation

lower,

more

stable

and

more

predictable.

Sweden's

experiences

in

the decades before and after the introduction of the inflation target provide a rough idea of the significance of inflation targeting for the development of prices and wages - severe fluctuations in the 1970s and 1980s were followed by very stable development after the introduction of inflation targeting (see Figure 1).It

has benefited economic development in Sweden.

This is because more predictable price developments make borrowers and savers feel more secure in how inflation will develop and create

good

conditions

for

economic

decisions.

This

lowers

borrowing

costs

and

thereby benefits investments.

Investments and new recruitments are facilitated by companies' ability to make a reasonably good prediction of price and wage cost increases over the lifetime of an investment.

The less uncertainty there is over future price developments, the easier it also becomes

to

agree

on

conditions

for

various

contracts,

not

least

the

wage

agreements negotiated by the labour market parties.

All in all, it is thus not unreasonable to consider that inflation targeting has contributed towards the higher average growth we have experienced over the two decades since targeting was introduced, as compared with the preceding period.1 The Swedish inflation target was announced in January 1993 and started to be applied in 1995.

For a more indepth review of the relationship with academic research and countries that had previously adopted inflation targeting, see Berg, C., 'Experience of inflation targeting in 20 countries', Sveriges Riksbank Economic Review 2005:1, Sveriges Riksbank.

## It is important that inflation expectations are not too lowThere is consequently a lot to be gained from having low, stable and predictable inflation.

But it is also important that expectations of future inflation are not too low.One reason for this is that inflation allows wages to develop more weakly in certain areas without requiring nominal wages to be cut.

This means that unemployment can be avoided when

changes

occur

that

reduce

the

demand

for

certain

types

of

knowledge,

skill

and experience.However, inflation expectations also affect the strength of the Riksbank's primary monetary policy weapon - the repo rate - and thereby the Riksbank's ability to stabilise the Swedish economy and lead it out of crises.This is a product of the way inflation expectations affect real interest rates.

In the same way as the figures for GDP growth we usually discuss refer to real growth, which is to say growth adjusted for inflation, there is namely reason to adjust interest rates in the economy for inflation - in particular, to determine how much stimulus monetary policy is supplying.

There are good reasons to subtract the effects of inflation on debts and saving.

For example, a loan for an investment becomes less burdensome to repay the more the price of the goods the borrower is

selling

has

increased

over

the

period

in

question.

And

the

lender,

correspondingly,

has reason to consider how much the money is worth when the loan is eventually repaid.

Another way of putting it is that those borrowing and lending must consider how much of the amount lent they expect to be 'eaten up' by inflation.

The economically-significant real interest rate is therefore the usual nominal rate with a deduction for expected inflation:

## Real interest rate = nominal interest rate - expected inflationHow expansionary the interest rate policy is, which is to say how low the real interest rate level is, is thus determined both by the nominal interest rate level and by expected inflation.

This also

means

that

how

expansionary

the

level

of

interest

rates

can

be

made

is

not

just determined by how far the nominal interest rate can be cut but also by how high inflation is expected to be.

When inflation is expected to be high, the real interest rate can be made very low, but this also means that, as inflation expectations fall, the scope for cutting the real interest rate also decreases.The fact that inflation expectations were anchored around the target of two per cent meant that the

low

nominal

interest

rates

of

2009

and

2010

(see

Figure

2)

gave

households

and companies very low real interest rates and supported the recovery of the Swedish economy.

With lower inflation expectations, the same interest rate policy would have had a less powerful stimulatory

effect

and

that

would

probably

have

meant

lower

employment

and

even

lower inflation in recent years.Inflation expectations are thus of vital importance for how expansionary monetary policy is and how expansionary it can be made when the Swedish economy is subjected to new severe stresses.

The stimulus provided by a really low real interest rate can make it possible to avoid more prolonged low interest rate periods with the drawbacks in the form of rising indebtedness and exaggerated risk-taking that we are now concerned about.

But if inflation expectations are too low, not even the lowest possible repo rate may be enough to push the real interest rate down to the desired level.To sum up, it is thus of great benefit to the Swedish economy if households and companies, savers and investors, expect a future rate of inflation that is on a reasonably low level and that their

expectations

more

or

less

correspond.

The

key

to

such

jointly-agreed

inflation expectations is that the inflation target of two per cent is seen as credible, which is to say that all parties expect that the Riksbank will be able to hold inflation close to the target in the period ahead.

## Inflation expectations were losing their stable footing at two per centUnfortunately, one of the unusual circumstances prevailing at the start of 2015 was that longterm inflation expectations were losing their stable footing around the target of two per cent.

Of course, there are no perfect measures of inflation expectations and it is not obvious whose expectations

are

most

important,

but

we

carefully

monitor

the

survey-based

measures

of expectations provided by Prospera.

The decrease in inflation expectations five years ahead that took place in the period up to the end of 2014 was worrying (see Figure 3).

Pricing on the bond market gave the same view of falling long-term inflation expectations.If

this meant that doubts were now starting to arise about the two per cent target, this was perhaps not so strange, considering that inflation at this point had been low for an extended period of time.

There was certainly reason to believe that this was at least partly the result of temporary factors.

The Riksbank's own analyses pointed to the strengthening of the krona exchange rate between 2009 and 2013, the weak level of economic activity abroad and falling energy

prices.

We

also

noted

an

unusually

low

interest

among

companies

in

raising

their prices,

despite

rising

costs.

Conceivable

explanations

for

this

included

decreasing

inflation expectations

and

perceived

uncertainty

over

the

economic

outlook,

as

reported

by

the companies in our Business Surveys. 2The unusually low inflation

in

recent

years

is

something

we

have

shared

with

many

other countries.

This may have strengthened the perception that there are forces in motion making it

impossible

for

the

Riksbank

to

reach

the

inflation

target.

There

has

been,

not

least,

an emphasis on the effects of globalisation and digitisation on costs and competition.

However, as my colleague in the Executive Board, Martin Flodén, pointed out in a speech last autumn, it is difficult to see why this should have persistent effects on the rate of inflation in particular and why it has not prevented higher inflation in countries like Norway, Canada and Australia. 3 In addition, these factors were relevant when Sweden had a higher rate of inflation, just a few years ago.Regardless

of

the

underlying

reasons,

it

would

be

very

unfortunate

if

long-term

inflation expectations were to drift away from the inflation target.

We would then start to lose everything we gained by having an inflation target.

## Inflation prospects are influenced by international developmentsAt the same time, at the start of 2015, the European Central Bank (the ECB) had announced bond purchases in an amount of EUR 60 billion per month to make its monetary policy more expansionary.

Of course, these measures will eventually have positive effects on inflation in Sweden as they provide welcome stimulus for an important Swedish export market.

But, by weakening the euro, the ECB's measures risked exerting price pressure on a significant portion of Swedish imports over the short term.In

addition,

the

price

of

oil

had

fallen

sharply

in

2014

and

continued

to

fall

in

2015.

The international development of the price of oil directly influences inflation in Sweden via the price of fuel oil and, not least, the price of petrol.

Over time, it can also have effects on other prices, as it affects companies' energy and transportation costs.

It is true that, in normal cases, a fall in the price of oil has a brief effect on the actual inflation figures.

But as the price of petrol in particular is so very visible for so many people, it may have a disproportionately high impact on how inflation is perceived and thereby possibly also on inflation expectations.2 See, for example Andersson, B., Corbo, V. and Löf, M., 'Why has inflation been so low?', Sveriges Riksbank Economic Review 2015:3, Sveriges Riksbank.3 'Sweden needs its inflation target', published 13 October 2015.We have also had a year characterised by a large degree of uncertainty over international developments in general.

Greece's membership of the single currency and possibly, therefore, the entire European monetary union was, at moments, on the ropes.

The conflict in Ukraine and the sanctions levied

on

Russia

had

consequences

for

the

Russian

economy

but

also created unease over the political and economic development of eastern and central Europe in general.

We saw drastically reduced demand from the global growth engine of recent years, China.

This gave new fuel to concerns over an imminent hard landing of the economy there.

The severe conflicts in the Middle East started to make themselves increasingly felt via a heavy increase in the numbers of people seeking safety in Europe.

The possible effects of the central banks acting out of step - after a number of years of crisis policies - also led to a degree of concern.There is always uncertainty but, nevertheless, my impression is that it has been unusually high over the past year.

Uncertainty in itself can cause problems as it can lead households and companies to hold off consumption and investment, and can reduce companies' willingness to raise their prices.

Everything else being equal, a higher degree of uncertainty therefore argues for a more expansionary monetary policy.

In addition, greater uncertainty over international developments also entails a greater risk that the Swedish economy will be exposed to such strong negative pressure that we will end up in a really serious situation with persistently falling prices and employment.

A desire to lower the chances of such a situation may, in itself, argue for a more expansionary monetary policy.

## A more expansionary monetary policyAt

the

start

of

2015,

we

thus

found

ourselves

in

an

unusual

situation

with

a

series

of circumstances that suggested that monetary policy needed to be more expansionary: declining confidence in the inflation target, the measures adopted by the ECB to weaken the euro, the risk that the falling oil price would put further pressure on inflation expectations and increased uncertainty over international developments.Consequently, there was a need to strengthen confidence in the inflation target through clear signals of the Riksbank's ability and willingness to bring inflation back to the two per cent target in a controlled form.

We needed to clarify and practically demonstrate that monetary policy had more to give.The repo rate was already at a historically-low zero per cent and even the interest rates we sometimes

call

the

final

interest

rates

-

that

is,

those

actually

paid

by

households

and companies - were at historically low levels.

But interest rates needed to be even lower and we needed to counteract the increasingly rapid appreciation of the krona.

## Negative interest rate?The most obvious measure was to cut the repo rate further, that is to make it negative - to introduce what, in everyday parlance, was starting to be called a negative interest rate.

When we cut the repo rate to zero per cent, we did not observe any major problems.

But would making the repo rate negative and quite simply forcing the banks - and, ultimately, perhaps their customers - to pay to keep money in an account really have the same impact on final interest

rates

for

households

and

companies

and,

if

so,

could

it

be

implemented

without causing problems elsewhere in the system?

One objection towards negative interest rates is that people will choose the alternative of keeping cash in their mattresses.

As this would be troublesome and not entirely risk-free, it can be imagined that most people would want to hold off stuffing their mattresses with cash as long as interest rates stay only slightly negative, but it

is,

of

course, difficult to gain clarity as to exactly where such a boundary would lie.

If the banks were unwilling to introduce negative deposit rates, would they then attempt to maintain their earnings by not cutting their lending rates either, in the eventuality that the repo rate was cut to below zero per cent?

There are some international experiences, albeit short-lived, ofnegative interest rates that can be looked at - from the euro area, Denmark and Switzerland - but how would the Swedish system react?

## Purchasing government bonds?Another measure with the potential to push interest rates down and counteract the excessively rapid

appreciation

of

the

krona

was

the

purchasing

of

government

bonds.

There

were significantly more comprehensive historical and international experiences of this than there were of negative interest rates.The bond purchases made by a number of central banks in the wake of the global financial crisis were aimed at pushing down yields on longer maturities.

Put simply, the idea is that, if the central bank purchases part of the available debt securities, anybody wishing to have these in their portfolios will be forced to compete for a smaller supply.

This will push up the prices for debt securities so that yields will decrease.Of course, assessments of the effects of central banks' bond purchases vary between different analyses, but there is a lot to suggest that three major central banks (the Federal Reserve, ECB and Bank of England) have succeeded, to some degree, in pushing down long-term yields and weakening their exchange rates. 4

But there has, of course, been some uncertainty over what

the

effects

would

be

in

Sweden's

case.

There

have

also

been

risks

to

consider,

for example that the functionality of the Swedish bond market may start to become impaired if the Riksbank were to purchase a large portion of the supply.There are also other measures on the menu.

One of these is lending to companies via the banks to reduce the differences between the final interest rates for companies and the yields on government securities with corresponding maturities.

Another possible measure, justified by

the

great

significance

of

the

krona

exchange

rate

for

the

development

of

inflation,

is conducting currency interventions.

## A cautious combination of a negative repo rate and bond purchasesSo how have we chosen to act, and what have the results been, so far?

Up to this point, we have kept to changes to the repo rate and repo rate path, and purchases of government bonds.

As it has not been completely certain how these would function in practice, there has been reason to proceed cautiously.

We have combined several measures over the past year to make the combined effect sufficiently great.

Over a number of stages, we have cut the repo rate and/or

the

repo

rate

path,

at

the

same

time

as

we

have

announced

and

initiated

bond purchases in amounts that have been increased in several stages (see Figure 4 and Figure 5).

In addition, in our communication, we have emphasised our preparedness, if necessary, to also rapidly increase monetary policy stimulus between the ordinary monetary policy meetings held every second month.

In March 2015, we did exactly this - we took a decision on new monetary policy stimulus between two ordinary meetings.

## The repo rate cuts have largely workedAs regards the repo rate cuts, so far we have been able to observe that lending rates followed to a normal extent, while deposit rates have stopped at zero for everybody except some larger companies.4 For a review of current studies and an analysis of the effects in Sweden, see De Rezende, R.

B., Kjellberg, D. and

Tysklind,

O.,

'Effects

of

the

Riksbank's

government

bond

purchases

on

financial

prices',

Economic Commentary no. 13, 2015, Sveriges Riksbank.

## The bond purchases have had the intended effect on interest ratesTo get an idea of the effects of the bond purchases, staff at the Riksbank have studied the financial

markets'

immediate

reactions

to

the

announcement

of

the

decisions. 5

On

those occasions on which the decisions were deemed unexpected, yields fell over the days on which the decisions were announced.

In addition, they fell in comparison to corresponding yields abroad, for example in Germany.

It therefore seems reasonable to conclude that the bond purchases have pushed interest

rates

in

the

economy

down

-

Swedish

government

bond yields are now probably lower than they would have been without the purchases.

These effects are in line with those observed in studies of the Federal Reserve's bond purchases in the United States.Our analyses of the financial market's reactions to the monetary policy decisions have also concluded that the decisions have entailed a weakening of the krona exchange rate.It thus seems to be the case that the additional monetary policy measures that we introduced over

the

past

year

have

given

us

lower

interest

rates

and

a

weaker

krona

than

we

would otherwise have.

This means that the measures have probably achieved and are continuing to achieve greater demand for domestically-produced goods and services, higher employment and

thus,

ultimately,

greater

cost

and

price

increases

than

we

otherwise

would

have experienced.The monetary policy conducted last year can therefore be said to have contributed towards turning the development of inflation and inflation expectations around (see Figures 3 and 7).The positive effect of last year's measures on inflation expectations is also suggested by the slight increase in what is known as inflation compensation - that is, the difference between the yields for nominal and real government bonds - in conjunction with the announcements of repo rate cuts and bond purchases that came as surprises.

## Standing prepared to make monetary policy more expansionaryInflation and inflation expectations are now higher than they were one year ago.

But, over the autumn, the development of inflation was weaker than we predicted and the rise in inflation is still

largely due to the krona being weak.

If the rise in inflation is broken, confidence in the inflation

target

may be weakened.

We are therefore prepared to do even more if it proves necessary to safeguard the inflation target.We still have many possible measures in our toolbox.

Experiences from the past year suggest that

cuts

to

the

repo

rate

and

repo

rate

path

also

work

below

zero

and

that

purchases

of securities form a good complement.

We can do more in this style if we deem that inflation prospects are changing.

Loans to companies via the banks are another possibility that I have already mentioned.

In addition, the Riksbank is prepared to carry out currency interventions if the exchange rate develops in a way that is not compatible with a rise in inflation to two per cent.

The aim of this would not be to influence the long-run krona rate, but to counteract an overly rapid strengthening before inflation has stabilised around 2 per cent.I hope that my comments so far have made clear that confidence in the inflation target has been

given

the

highest

priority

by

the

Riksbank

and

that

monetary

policy

has

contributed towards the favourable development of the real economy.

At the same time, since 2012, we have been careful to point out that a situation with low interest rates over a long period of time may create imbalances on the financial markets and on the housing market.

We have therefore clearly

communicated

to

the

Government

and

other

authorities

that

it

is

important

to

use various measures to limit risk-taking in the economy.

My assessment so far is that significantly5 De Rezende, R.

B., Kjellberg, D. and Tysklind, O., 'Effects of the Riksbank's government bond purchases on financial prices', Economic Commentary no. 13, 2015, Sveriges Riksbank.BIS central bankers' speechesmore commitment will be required to obtain a functioning housing market in Sweden and to reduce the risks of household indebtedness.

The risk otherwise is that we will create new problems that may lead to low growth further on and new difficulties for monetary policy to reach the inflation target.

I

am concerned about Sweden's position as one of a handful of countries in Europe that has not succeeded in getting a functioning macroprudential policy into place.

With such a large financial system and the obvious major vulnerabilities present in the Swedish economy, our focus should be on urgently adopting measures.

## Valuable evaluation of monetary policyWe thus have an unusual time behind us that has required unusual measures over the past year.

Under such circumstances, it is natural to wonder, for example, how well the inflation target is functioning and which areas monetary policy should be responsible for.

It therefore seems

appropriate

that

the

Riksdag

Committee

on

Finance

has

just

published

its

latest assessment of monetary policy. 6

First and foremost, I would like to say that it has been a privilege to have my work reviewed and assessed by people with such impressive academic and

practical

credentials

in

the

area

of

monetary

policy

as

those

possessed

by

Messrs.

Goodfriend and King.

Assessments are a key ingredient in every kind of work to improve operations

and

this

assessment

contains

many

reasonable

opinions

and

suggestions

for discussion and further work.

We will do this over the spring, before submitting our consultation response in April.

Today, I will just express my own initial reactions to a few of the elements in the assessment that come closest to the theme of today's address.First and foremost, I cannot, of course, avoid noting that Goodfriend and King also consider that Swedish monetary policy since the introduction of inflation targeting has been an overall success.

Neither is there any doubt that they support an inflation target as the starting point for monetary policy.However, they would like to switch target variable to the CPIF, that is the CPI with a fixed mortgage rate.

It would not be difficult for us to make such a change, as we already focus most of our analysis and communication on the CPIF.

At the same time, I think that there may be reason

to

evaluate

several

possible

measures,

for

example

the

internationally-comparable measure

HICP,

as

my

colleague

on

the

Executive

Board

Per

Jansson

has

previously discussed in a speech. 7I appreciate how much Goodfriend and King have endeavoured to base their assessment on the information and experience available at the time of each individual decision, rather than proceeding on the basis of everything we know today about how developments turned out.

As they note, we have been through a difficult period with major challenges and difficult decisions.

One consequence of this is that it has been particularly difficult to make a good forecast of the repo rate and to take into consideration the repo rate expectations reflected at that moment by pricing on the financial markets.

However, speaking for myself, I have always seen the repo rate path as a component of our ambition to be transparent as it shows which repo rate we include in our forecasts.

And we always emphasise that the repo rate path itself is a forecast and not a promise.One important

source

of

the

difficulties

that

Goodfriend

and

King

point

out

is

the

unclear allocation of roles, responsibilities and instruments for managing the work of financial stability and macroprudential policy in Sweden.

As I have already mentioned, I consider sorting this matter out to be a matter of great urgency, considering that Sweden has one of Europe's largest banking systems in relation to GDP.6 Goodfriend, M. and King, M., 'An assessment of Swedish monetary policy 2010-2015', Riksdag Committee on Finance, Sveriges Riksdag, 2016.7 'Time to improve the inflation target?', published 3 December 2015.This

spring,

Goodfriend

and

King's

assessment

will

provide

an

excellent

basis

for

the discussion of monetary policy and the issues that a modern central bank must manage.

These unusual times are placing great demands on both monetary policy and macroprudential policy.

It is important that we are able to meet these challenges in the right way.Figure 1.
