Suppose we have an inflation in a country with an annual 2% and we get a loan for an annual 1% (real interest). Is the money we receive free? This is a common practice in some European countries, where the mortgages are around 1% fix rate plus the Euro Interank Offered Rate. If so, why? Are the banks loosing money by lending in such low rates?

    $\begingroup$ Is the interest of $1\%$ real or nominal? $\endgroup$ – Regio May 8 '19 at 21:36

  • $\begingroup$ To be clear, we are talking about an interest rate = EURIBOR + 1%? $\endgroup$ – dismalscience May 10 '19 at 1:21

Inflation: 2% Interest: 1%

This means the real rate is 3%. So no; not free money.

Free money would be negative interest rates. Example: Inflation: 0%. Interest on loan I get from the bank: -1%. This would mean they are paying ME 1% to take the loan from the bank.

Negative interest rates are a real practice, with many historical examples that can be researched.

The banks are theoretically losing 1%(+2% inflation) on the loaned amount, however it's important to understand that deals are made among negotiations with central banks in the background that can still produce gains from this.

  • $\begingroup$ If inflation is 2% and nominal interest is 1%, then the real interest rate is -1%. $\endgroup$ – Acccumulation Jun 10 '19 at 0:29
  • $\begingroup$ Sorry but that is not correct, you do not subtract them, you add them for the real interest rate. If I take a loan out from the bank at a nominal interest rate of 1%, and inflation is 2%, then I'm effectively paying 3%. The bank's return on the loan however is -1%. $\endgroup$ – Clinical_Coder Jun 10 '19 at 18:06

You have the right intuition.

However, 1% is usually the real interest rate.

Real interest rate = nominal interest rate - inflation

So, you are actually, usually, paying a 3% annual rate.

If that is not the case, your question does not specify if 1% is nominal or real, then just having inflation of x% does not mean that you are increasing your wealth my that much each year.

Example: Inflation is 10%. The best investment opportunity provides a return of 0.5%. By the end of the year, I am still losing 9.5% of my wealth. But does that mean that I should not invest at all? If I don't then I will lose 10% which is wrose.

I hope that helps.
