ARTICLE Higher interest-rate sensitivity
in the Swedish economy
Interest-rate sensitivity in the Swedish economy has shown a trend
increase over the past thirty years. Households have borrowed increasing
amounts for their housing purchases over time. Moreover, the interest-
rate fixation period on mortgages is short. When the policy rate is raised,
the cash flow of households with loans is affected, at the same time as
lower housing prices limit the borrowing capacity for mortgagors. Among
companies, it is primarily those in the commercial property sector that
have experienced an increase in indebtedness and sensitivity to interest
rates.
The Riksbank's analyses show that the increased indebtedness among
households has led to monetary policy now having a greater impact on
demand in the economy. The policy rate does not need to be raised as
much to have the same tightening effect on the economy as before,
which is an important aspect to take into account in the monetary policy
decisions.
High indebtedness increases sensitivity to interest rates
in the economy
According to traditional economic theory, monetary policy impacts demand in the
economy mainly by affecting the real interest rate and the balance between
consumption now and in the future. The traditional monetary policy analysis is based
on a representative household, but more modern analysis has increasingly empha-
sised other channels and the fact that households differ. Put simply, one can imagine
two types of household, one consisting of borrowers and one of savers. Borrowers
can be assumed to have a higher propensity to consume than savers, as a result of
credit constraints, which means that their consumption is affected more by changes in
income and interest rates. When the interest rate changes, a transfer of income
occurs between borrowers and savers a so-called cash flow effect.
36
The fact that
total consumption is affected is due to the borrowers’ propensity to consume being
higher. If the borrowers are also highly indebted and have mortgages with short
interest-rate fixation periods, the effects will be greater and come sooner. As the

interest rate affects housing prices, it can also affect the scope of households to con-
sume by borrowing against their home as collateral a so-called loan collateral
effect.
37
This effect will be greater if the borrowers have a high level of debt in rela-
tion to the value of the home.
The Riksbank has long been analysing the increased risk sensitivity in the Swedish
economy, partly because it impacts the effects of monetary policy.
38
Debts among
Swedish households have shown a trend increase for decades (see Figure 50). House-
holds living in tenant-owned housing also have indirect debts via the loans taken out
by their housing cooperatives. The Riksbank has also repeatedly pointed out the risks
linked to the increased debts. They are high from both a historical and an inter-
national perspective.

Compared with many other countries, the interest-rate fixation period is very short in
Sweden. The percentage of mortgages with variable interest rates rose from below
10 per cent in 1996 to around 60 per cent in 2015. Even though the percentage of
fixed-rate loans among total loans has increased somewhat recently, around
80 per cent of the loans have a remaining interest-rate fixation period of 2 years or

less (see Figure 51). This means that changes in interest rates have a greater and
faster effect on household demand in the economy. And this applies both compared
with most other countries and compared with earlier periods when the Riksbank
changed the interest rate.

Companies’ debts have also increased over time. Figure 52 illustrates the effect of
higher interest rates on the Swedish household and corporate sectors. With regard to
the corporate sector, it is difficult to forecast the interest-to-income ratio, as compa-
nies borrow through more sources and use interest rate derivatives. Estimates by the
Riksbank last spring indicated that an upturn in general interest rates of 3 percentage
points would mean the interest-to-income ratio was back at around the levels prevail-
ing in 2012, when the policy rate was between 1 and 2 per cent. This indicates that
companies on the whole are not very sensitive to interest rates.
39
One should bear in
mind that the denominator in companies’ interest-to-income ratio, that is, their earn-
ings, can fall in a deteriorating economic situation and contribute to interest-to-

income ratios rising more than is shown in Figure 52.
40
There are also major differ-
ences between companies and sectors. As we will see further on, commercial prop-
erty companies are particularly sensitive to interest rates.
The right hand image in Figure 52 shows that when the policy rate rises in accordance
with the Riksbank’s forecast, households’ interest-to-income ratio will in three years’
time be on a par with the levels in the mid-1990s, when the policy rate was over
8 per cent. The high sensitivity to interest rates, together with household consump-
tion comprising around half of GDP, are explanations for much of the earlier analysis
having focused on the situation of households. This article also puts greatest focus on
households, although we also discuss companies’ interest-rate sensitivity.

Note. For companies, the interest-to-income ratio is calculated as interest expenditures after
interest deduction in relation to operating profits, for all non-financial corporations. In the
scenario with the higher interest rate, it is assumed that the earnings remain unchanged. For
households, the interest-to-income ratio is calculated as the households’ interest expenditure
as a percentage of their disposable income and is based on everyone being able to use a 30 per
cent interest deduction. Disposable income is expressed as a four-quarter moving total. Broken

Consequences for households and companies when the
interest rate rises
Highly indebted mortgagors will experience large negative cash flow
effects...
The aggregated debt-to-income ratio of around 200 per cent hides large differences
between households, partly dependent on where in Sweden they live and whether

they own their own home.
41
Around half of households in Sweden have a mortgage,
and among these the debt-to-income ratio is almost twice as high as for the house-
hold sector as a whole. An increasing number of new mortgagors have also taken on
more debt in relation to their incomes (see Figure 53).
42
Almost 60 per cent have
mortgaged themselves for more than 300 per cent of their income before tax, corre-
sponding to around 400 per cent of disposable income. The fact that households are
more indebted means that the cash flow effect will be greater than on previous occa-
sions when the Riksbank raises the interest rate. For highly indebted mortgagors, the
borrowing scope may decline significantly when the interest rate rises in line with the
Riksbank's forecast (see Figure 53). As the interest-rate fixation period is so short
among Swedish mortgagors, the impact also comes quickly, which is shown in
Figure 52.

the Riksbank's forecast for household mortgage rates for the third quarter of 2025. The calcula-
tions also include other loans, and the interest rate on these is also expected to increase. The
estimate is an interpolation based on the calculations in Finansinspektionen’s Mortgage Report

...and have reduced borrowing scope when housing prices fall
When the Riksbank raises the policy rate, housing prices are also affected. The fact
that housing prices have fallen recently, and are expected to continue to fall in the
Riksbank’s forecast, is linked both to household facing higher mortgage rates in near
term and an upward revision in their expectations of interest rates in the long term.
43
The falling housing prices in turn have an effect on household consumption via the
loan collateral effect.
Many of the new mortgagors are households that are extending the loans on their
existing home to finance, for instance, consumption and renovation of their home.
44
Despite prices having risen substantially over a long period of time, many new mort-
gagors have a high debt, measured as a share of the home’s value, that is, a high loan-
to-value ratio (see Figure 54). This means that the scope to take on new loans can be
severely limited if housing prices fall. Figure 54 shows that a price fall of 15 per cent,
compared with autumn 2021, which is in line with the Riksbank's forecast, means that
around 45 per cent of the new mortgagors have a loan-to-value ratio of more than
85 per cent and thereby hit the mortgage cap. The fact that falling housing prices can
significantly limit the opportunities to borrow against the home can increase the
impact of monetary policy on consumption going forward. At the same time, it is im-
portant to point out that the loan-to-value ratio is lower for the stock of all mort-
gagors than for new ones, as housing prices previously rose over a long period of
time.
45
However, these households will also have a reduced borrowing scope accord-
ing to the same mechanisms when housing prices fall.

45
According to Finansinspektionen’s mortgage survey from 2022, the average loan-to-value ratio in the
stock of mortgagors is 53 per cent, which can be compared with 64.5 per cent among new mortgagors in
the sample.

Mortgagors are in general affected more than other households when interest rates
rise. The National Institute of Economic Research's Economic Tendency Survey shows
that it is owners of single-family dwellings that have become the most pessimistic
about their financial situation in the near future and with regard to the purchase of
capital goods (see Figure 55).
46
New analyses from the Riksbank also indicate that the
purchases of cars are affected more by higher interest rates in municipalities where
household debt is high.
47
46
One possible explanation is that house-owners have previously invested a much larger share of their
disposable income in housing expenses than those living in tenant-owned apartments; see The Swedish
Mortgage Market 2022, April 2022, Finansinspektionen. This reduces the margins for meeting rising
interest rates, for instance. A further possible explanation is that house-owners are also affected to a large
degree by, for instance, rising energy prices.

The lack of current microdata on household assets and savings makes it difficult to
assess how household consumption will react when interest rates rise. One way for
households to manage rising interest rates is to use their savings. Even if the house-
hold sector as a whole has a substantial holding of liquid assets, the estimates indicate
that these are very unevenly distributed.
48
The Riksbank has for a long time called for
up-to-date microdata on households’ debts and assets, not least to enable a better
understanding of the different channels from monetary policy to households’ con-
sumption decisions.
The increasing indebtedness among companies is driven by commercial
property companies
As we saw in Figure 52, interest-rate sensitivity does not appear to be especially high
in the corporate sector as a whole, when looking at the direct effects of interest rate
expenditure. Households’ high interest-rate sensitivity, on the other hand, can affect
companies indirectly through changes in demand.
In the corporate sector, commercial property companies stand out significantly.
49
They are more indebted than other companies in general and have driven much of
the increase in indebtedness in the corporate sector in recent years (see Figure 56).
The increase has been both through bank loans and market funding in the form of
debt securities. Commercial property companies are therefore affected substantially
by rising interest rates. The Riksbank’s analysis from last spring indicates that com-
mercial property companies would see their interest-to-income ratio rise from 25 to

60 per cent if interest rates rise by 3 percentage points. These are much higher levels
than for the corporate sector as a whole (see Figure 52).

The commercial property companies may need to adapt their operations as a result of
interest rates rising in coming years.
50
They can do this by reducing investment in
existing or new property, particularly rental and office properties. Rising interest rates
can also, when combined with tighter credit terms and weaker economic activity, lead
to the value of the companies’ properties falling and their earnings deteriorating. As
the Swedish banks have large exposures to commercial property companies, potential
problems in these companies can have a very negative effect on financial stability.
51
Problems in the property companies can lead to increased credit losses in the Swedish
banks and reduced capital levels, which in turn can have consequences for the credit
supply in the economy. Ultimately, such a development would have great significance
for both the macroeconomy and monetary policy.
50

This is been pointed out by both the Riksbank and Finansinspektionen. In January 2020,
Finansinspektionen decided to raise the capital adequacy requirements for the banks’ lending to
commercial properties.

Monetary policy conclusions interest rate raises have a
greater impact than before
One conclusion of the interest-rate sensitivity in the economy showing a trend
increase over the past thirty years is that monetary policy has had an increasingly
large impact and that smaller interest rate adjustments are needed to attain the same
stabilisation policy effects as before. But how large is the quantitative significance?
Figure 57 is based on new analysis from the Riksbank and shows the effect on house-
hold consumption of an interest rate increase for various sub-periods that are sorted
according to the average debt-to-income ratio.
52
The debt-to-income ratio is currently
around 200 per cent, which is higher than the average debt-to-income ratio for the
final sub-period in the figure, which is 170 per cent. A rough estimate based on the
correlation in the figure indicates that an increase in the policy rate of one percentage
point at present means that consumption is slowed down around twice as much as
15 years ago, when the debt-to-income ratio was around 150 per cent. Although
these results cannot show that the greater consumption effect is completely due to
higher indebtedness among households, there are good arguments in favour of this
from other studies.
53
Highly indebted households have thus taken on greater signific-
ance for the monetary policy transmission.
54
All in all, the Riksbank's analysis indicates that the policy rate does not need to be
raised as much as before to obtain the same tightening effect on the economy. Even if
the policy rate is expected to rise a lot in the short term, the upturn is nevertheless
relatively limited in a historical perspective, with regard to the interest cycle as a
whole.

A new study from the Riksbank also shows that interest rate increases have a greater effect on disposable
incomes and the number of newly-registered cars in municipalities with relatively highly indebted house-
holds. See S. Laséen (2022), ”Hushållens skuldsättning och penningpolitik: ett regionalt perspektiv”
