What effect would sovereign default of a European country have on personal debt, especially a mortgage?

  • Does the country stay within the Euro? Is personal debt maintained as EUR, or converted to a newly created currency? How does the new currency fare over time? Are local banks (who own the personal debt) still in business? These are just some of the factors on which the answer may depend. – ALAN WARD Jul 9 '15 at 17:24


This article points out three likely effects (direct and indirect) sovereign default can have on the individual:

  • capital flight and currency collapse. Inflation jumps, standard of living drops.
  • international financial system closes the door. The country must pay penal rates to get their hands on money.
  • businesses and individuals must look to foreign sources for loans.


This looks at how a default may not look like a default - even if it is. But again, how defaults can impact the man in the street:

  • taxes increase
  • inflation increases
  • poor job situation stays poor longer. Poor housing market stays poor longer.


The fascinating Argentine default is described in a blow-by-blow format here, including brief references to things like unemployment and personal savings:

  • foreign investment stops
  • run on banks
  • massive inflation spike
  • currency-of-savings converted (!)
  • currency value crashes
  • development of "alternative" and "informal" economic frameworks (e.g., barter networks)
  • unemployment spikes
  • tourism, agriculture (exports) crash


Remember, though. Not all defaults are the same. And a modern-European country's default may look very different to what has occurred elsewhere.

    A summary of the articles would be quite useful, making the answer stand on its own with further detail available by following the links. – George Marian Mar 19 '11 at 20:13

This is a hard question to answer. Government debt and mortgages are loosely related. Banks typically use yields on government bonds to determine mortgage interest rates. The banks must be able to get higher rates from the mortgage otherwise they would buy government bonds.

Your question mentions default so I'm assuming a country has reneged on its promise to pay either the principal or interest on government bonds.

The main thing to consider is "Who does not get their money?". In other words, who does the government decide not to pay. This is the important part. The government will have some money so they could pay some bond holders. They must decide who to shaft.

For example, let's look at who holds Greek government debt. Around 70% of Greek government debt is held outside Greece. See table below.

enter image description here

The Greek government could decide to default only on the debt to foreign holders. In that case the banks in France and Switzerland would take the loss on their bonds. This could cause severe problems in France and Switzerland depending on the percentage of Greek bonds that make up the banks' assets. Greek banks would still face losses, however, since the price of their Greek bond holdings would drop sharply when the government defaults. Interestingly, the losses for the Greek banks may be smaller than the losses faced by the French and Swiss banks. This is usually the favored option chosen by government since the French and Swiss don't vote in Greece.

Yields on Greek government bonds would rise dramatically. If your Greek mortgage is an adjustable rate mortgage then you could see some big adjustments upward. If you live in France or Switzerland then the bank that owns your mortgage may go under if Greece defaults. During liquidation the bank will sell their assets which includes mortgages and you will probably not notice any difference in your mortgage.

As I stated earlier: this is a hard question to answer since the two financial instruments involved (bonds and mortgages) are similar but may or may not be related.

    This 2011 answer is very interesting from 2015's point of view. Have we really moved forward on Greece in the last 4 years? More specifically, how can a private person do any forward planning of personal finance in these circumstances? – ALAN WARD Jul 9 '15 at 17:29

If the default happens through mass monetary inflation rather than openly ("We're not paying interest on our bonds") then make sure you pay off your house. There may not be a very long window to do so.

If the currency becomes worthless, then it depends on what you have of value that would be accepted by the lender as payment. If you don't have anything, the lender will take it back, as they're probably entitled to on the notes.

    Thank you mbhunter. But would mass inflation reduce relatively the size of existing mortgages?? – user3034 Mar 17 '11 at 9:17
  • This answer is completely wrong. In times of hyperinflation money is easy to get. You could sell your bicycle and pay off that $500,000 mortgage. – DJClayworth Mar 17 '11 at 15:42
  • @DJ: Yes, you can pay off your mortgage by selling your bicycle, for a short period of time. Hyperinflation doesn't last forever, and when they run out of space for the zeroes on the bills, it's done. You're stuck at that point. You've traded your life savings in that currency for whatever hard goods you own. Finito. Done. It's what happened in Weimar Germany. – mbhunter Mar 17 '11 at 16:18
  • @mbhunter You seem confused by this. Many things you say are simply wrong. If you have savings that's a whole different ballgame from having a mortgage, and yes you will lose them. In fact using your savings to buy a commodity that doesn't lose value is the first thing you should do if you think hyperinflation is coming. Keep the mortgage and pay it off later by selling something small whose price is now extremely high. – DJClayworth Mar 18 '11 at 14:20
  • And "running out of space for zeroes on the bill" isn't the reason hyperinflation ends. If you are Weimar Germany, for example, you define a new unit of currency worth some huge multiple of the old one. Hyperinflation does of course end eventually, thankfully for the people suffering from it. You are not "stuck" at that point, you are probably thanking God that your life and the economy can return to some semblance of normality. – DJClayworth Mar 18 '11 at 14:28
