According to an article at Yahoo Finance, the Swedish central bank dropped its zero interest rate to -0.1 percent a couple of days ago (the article is dated to Thursday, February 12th, 2015).

Now, already in 2013 this article from Business Times reported that Swedish households were repaying their mortgages so slowly that it will take 140 years on average. It seems that the mortgage repayment system in Sweden is such that while a bank may set a theoretical limit on how soon the mortgage should be repaid, the individual is free to make interest-only repayments as long as they see fit. So the 140-year average length is not caused by lenders granting 140 year loans, but by the individuals simply paying them back at a rather slow pace.

If mortgage debts are already being paid on a rather low rate, can reducing the interest rate to below zero actually help the economy? Wouldn't this kind of decision just speed up a crash?

As to the Forex rate for the Swedish krona, can it be expected that this situation pushes down the value of the krona?

Update: My reason for asking this question is because of the assumption that the Central Bank interest rate controls the rate at which other banks lend money to individual customers. Thus the central bank would set the interest rate low so as to lower the interest rates of loans in the country, and through this, to stimulate lending. This is what for example USA did during the first decade of this century.

I would have thought that stimulating lending in a situation where mortgages are being paid back at an extremely low rate would be a recipe for a house price bubble and subsequent crash(?)

  • $\begingroup$ Having a negative interest rate is just to try to dissuade people from using the Swedish central bank at all, since they would be better off just holding cash. $\endgroup$ Commented Feb 16, 2015 at 5:54
  • $\begingroup$ about your update, your assumption is wrong, that's not what the central bank does. Indirectly, it does have an effect on mortgage rates (all interest rates will tend follow the direction of the central bank rate), however it's an overnight lending rate and isn't directly comparable to mortgage rates... Since banks in sweden require you to put down at least 15%, in combination with other factors, means that a bubble isn't as likely as you might think. $\endgroup$ Commented Feb 17, 2015 at 5:36

  • $\begingroup$ I just read an article (in a Finnish newspaper: hs.fi/talous/a1461643855882 [I do not have an english-language source at the moment]) about the housing market in Sweden. According to that house prices have increased about 44% during the last 5 years in Stockholm region and the average personal debt in Sweden is over 170% of income (in Stockholm region it is higher: 528% for people with home mortgage, and for some people as high as 750%). So it looks like a bubble in making but on other hand Sweden accepted lot of refugees who need to also live somewhere, maybe that will drive market $\endgroup$

There is some concern about the interest rates (currently at -0.5%) fueling a housing bubble in Sweden. This article at Fidelity states:

In a bid to track the ECB, Sweden has cut its interest rate below zero, a radical move that involves charging banks to hold some types of deposits with the aim of encouraging them to lend.

Similar trends have emerged in other small, open economies, such as those of Denmark and Switzerland, which also have subzero rates.

In Sweden, the central bank governor has warned that the low rates could be creating a housing price bubble.

A reason why this risk exists in particular for Sweden is because the regulation has allowed the borrower to pay only the interest on common mortgage types, and since the interest rates have been very low for many years, the sizes of these payments have been low.

These mortgages are referred to as "Swedish style mortgages" in this report published by the Swedish Central Bank (dated April 2015).

Overall the situation has stimulated borrowing and fueled the growth of the overall indebtedness of the households. Above report states on p. 4 that:

Sweden, in particular, has seen household indebtedness rise from 90% of disposable income in 1995 to 172% in 2014

Current situation is still as described as on page 14 in the Sweden - Selected Issues paper published by the IMF (dated August 2014), shown in below image.

increase of unamortized mortgages in Sweden until 2012

On p.15 this IMF report states that:

  1. If progress under the current voluntary approach remains limited, a binding maximum amortization period for new mortgages would be helpful. Swedish banks are working to raise amortization through voluntary means. However, the picture remains largely unchanged. The share of new mortgages granted in 2013 that has an amortization plan has remained broadly constant from 2012. And, of the existing mortgage stock, a significant 40 percent of households either increased or did not decrease their debt in 2013. For the remaining 60 percent of households, it would take 100 years to fully pay down their debt if they continued to amortize at current speeds.

In fact they attempted to regulate the mortgages last year but according to this article it looks like the proposed changes were rejected by an appeals court. The article states that

Under the original plans, customers would have been asked to pay two percent of the value of their mortgage every year until they had repaid 30 percent of the loan. They would then have been required to pay at least one percent a year until they hit the 50-percent mark.

But the watchdog backtracked after an administrative court of appeal in Jönköping in southern Sweden suggested that the proposed changes were not supported by Swedish law.

I am not sure however if they were able to pass that law later in some modified form.

Understandably the current level of indebtedness poses a large risk for the banks in the event of a downturn on the housing markets. However the already existing debt levels (as discussed in this report) in comparison to disposable income may make it difficult to implement drastic changes to the regulations.

The reason for the interest-rate cut you asked about seems to have been to avoid further deflation. One of the consequences of this has been, according to this article, an overall increase in house prices. So while at least two of the symptoms of a housing bubble (high prices and high levels of household debt) are present in Sweden, there are also factors that play against a US-style mortgage crisis, such as:

  • The ability of households to make interest-only mortgage payments without penalty for an extended period.
  • Large amounts of recent immigrants (refugees from mainly the middle east) that will require housing. In addition to this Sweden already had low levels of new construction even before the latest influx of immigrants.
  • The relatively small size of the country; people tend to not move geographically as far away as in USA for reasons such as employment and may stay at a particular address longer.

Update: According to this article, Sweden did change the maximum length of a mortgage to 105 years earlier this year.


First of all, that rate is the overnight deposit rate for banks depositing cash at the central bank, so it doesn't have a direct relationship with what people pay for their mortgages. (EDIT: yes, it does have an indirect relationship but it's not completely straightforward) People are still paying positive interest rates for their houses (and why would they not? No bank is going to give you money for loaning money from them!) And the rate to lend money from the central bank is still positive.

Essentially, the negative interest rate is there to dissuade the institutions that can interact with the Swedish central bank from depositing money there, since they would be better off just holding cash. So, this negative interest rate will cause them to have more reserves on hand, or, if they don't want to increase their reserves, they will have to loan out more money: and loaning out the money will have an indirect effect of stimulating the economy (since the people who need loans tend to be people trying to start companies or projects that will spend money). So basically, either it forces banks to be more solvent or it gets them stimulating the economy.

As you might be able to see, this only has a very remote relationship with mortgages or the mortgage rate, that being, it indirectly causes interest rates across the economy to stay low (since banks will want to loan out marginally more money, there will be some pressure downward overall on interest rates). This is definitely not anything that will speed up a crash, though arguably a long period of low interest rates may lead to people taking on too much debt which could cause problems if interest rates spike sometime down the road, but that's far away at this point.

It's hard to say what impact this would have on the exchange rate, just because any impact this would have is fairly subtle either way. The effect of market confidence in the krona and the Swedish Central Bank will likely have a more immediate and larger effect, which would actually strengthen the krona a bit.

  • $\begingroup$ "No bank is going to give you money for loaning money from them" - except that's exactly what some central banks are doing. And in some countries, mortgage rates are very closely linked to, and may even track, central bank rates. $\endgroup$

  • $\begingroup$ @EnergyNumbers if you look closely pretty much every bank with a negative interest rate is doing that for deposits only, which means that they are actually charging institutions for depositing money with them... they loan with a positive interest rate (although, in some cases the rate is low enough that it is arguably a steal)... I agree in general, a lot of interest rates tend to track central bank rates but it's an indirect thing. $\endgroup$ Commented Feb 16, 2015 at 18:59

    $\begingroup$ Actually @EnergyNumbers is correct in that the central bank setting negative interest rates can lead to the banks paying borrowers for lending money. This is the situation currently also in Denmark, as per an article in Financial Times (next.ft.com/content/7f4e2f4c-dde3-11e4-9d29-00144feab7de). The article mentions a Ms. Christiansen who due to Danish central bank policies received a negative interest rate for her three-year loan. In her case this does not equate to a large amount of money however; she receives about 7 Danish Krone (about 1 USD) each month from the bank. $\endgroup$
