Since the real rate of interest is negative, this means that the purchasing power of the savings have decreased over the  year.

Explanation:

Data provided:

Real interest rate = 7.85% - 12.3%

Or

The real interest rate = - 4.45%

Here,

Since the real rate of interest is negative, this means that the purchasing power of the savings have decreased over the  year.
