What is inflation and how does it erode purchasing power?

Inflation is the average rate of growth of prices of a set of goods and services in a economy over a certain period of time. It represents the continuous loss of purchasing power of the currency. In simple terms: over time, the same amount of money can purchase fewer and fewer goods at the supermarket.

The Real Plan and Currency Stability

Before July 1994, Brazil suffered from hyperinflation, with daily price adjustments and constant changes in currencies (Cruzeiro, Cruzado, Cruzeiro Real). The launch of the Real Plan structured a deep monetary reform that managed to control the runaway inflation. However, even controlled, inflation continued to exist. $1.00 in 1994 represents a purchasing power drastically superior to the same $1.00 today.

IPCA (Inflation Index) vs. IGP-M (Inflation Index): What are the differences?

There are different indices to measure price variations in the Brazilian market:

IPCA (Inflation Index) (National Broad Consumer Price Index): Produced by IBGE, it is the country's official inflation indicator. It focuses on the consumption of Brazilian families with incomes between 1 and 40 minimum wages and sets the target interest rate established by the Central Bank.
IGP-M (Inflation Index) (General Market Price Index): Calculated by the Getulio Vargas Foundation (FGV). Commonly known as the *rental inflation*, it adjusts most rental contracts and energy tariffs. It has a strong weight of commodities and wholesale prices (IPA), making it more sensitive to dollar fluctuations.

The Equation of Purchasing Power Loss

To calculate how much inflation has reduced the real amount of your money, we use the internal depreciation equation:

$$\text{Remaining Purchasing Power (\%)} = \frac{\text{Original Amount}}{\text{Corrected Amount}} \times 100$$

If the accumulated inflation over a period was 300% (which multiplies prices by 4), a product that cost $100 now costs $400. Your original $100 now purchases only 25% of that product, recording a 75% loss in real purchasing power.

Frequently Asked Questions

Because the accumulated inflation in Brazil since July 1994 under the IPCA (inflation index) is over 700% (and over 1,100% under the IGP-M index). This means that prices have risen approximately 8 to 12 times. To maintain the same exact standard of consumption that you had with $100 in 1994, you would need over $800 today.

Monetary correction is the update of the nominal amount of a contract, rent, judicial award, or investment based on an accumulated inflation index over the period. It serves to neutralize the loss of purchasing power of the currency, ensuring that the creditor receives exactly the same real amount (purchasing power) that was agreed upon in the past.

If you invest in an asset that pays 10% per annum and the annual inflation rate was 6%, your nominal return rate was 10%, but your real return rate (gain in purchasing power) was approximately 3.77% (calculated by dividing $(1 + 0.10) / (1 + 0.06) - 1$). That's why, for long-term protection, investors use indexed securities like the IPCA (inflation index)+ Treasury (which pays the period's inflation plus a fixed real interest rate).
