The analysis arrived at this figure for the South American country by taking the nominal interest rate of 13.75% and then subtracting a projected annual inflation rate of 6.81%.

Inflation rates are a major variable that impact real interest rates, as they have a significant influence on whether these interest rates are positive or negative. Inflation can be volatile and fast-moving, meaning that the benchmark Consumer Price Index (CPI) can change quickly from month to month.

One of the key distinctions between nominal and real interest rates is how much you pay to borrow versus purchasing power.

When the economy is healthy, nominal rates tend to be higher than in times of economic distress. The same concept that distinguishes real and nominal rates also distinguishes gross domestic product and nominal gross domestic product.
