The IPCA (National Consumer Price Index), an indicator that measures official inflation in Brazil, slowed from 0,82% in September to 0,14% in October, according to data released this Thursday (12) by IBGE (Brazilian Institute of Geography and Statistics).
Once again, the main factor containing the price increase was residential electricity, which registered a 1,92% drop in the month. This result only reinforces the influence that electricity bills have on inflation, showing how tariff variations have the power to alleviate or directly affect family budgets.
A survey carried out by Canal Solar Data on the trajectory of the IPCA (Brazilian Consumer Price Index) between January 2025 and October 2026 shows that inflation in Brazil registered, on six occasions, a variation of less than 0,24% — a monthly rate compatible with the 3% annual target set by the CMN (National Monetary Council).
In five of them, the reduction in electricity prices was among the main factors that contained more pronounced inflationary pressure and prevented the targets from being compromised.
January 2025 (IPCA of 0,16%): The year began with a sharp slowdown in inflation, driven by a 14,21% drop in residential electricity prices, reflecting the Itaipu Bonus discount on bills. The following month, the end of the benefit caused a 16,80% increase in the tariff, contributing to inflation rising to 1,31%.
August 2025 (IPCA of -0,11%): A new credit from the Itaipu Bond reduced residential bills and contributed to the first deflation of the period analyzed.
October 2025 (IPCA of 0,09%): The reduction in electricity prices also helped keep inflation close to stable, in a month marked by very little variation in consumer prices.
August 2026 (IPCA of -0,32%): Another round of Itaipu Bonds caused a 7,63% drop in residential electricity prices, contributing to the largest monthly deflation in the analyzed period.
October 2026 (IPCA of 0,14%): The change from the yellow to the green tariff flag reduced the price of electricity by 1,92%. This decrease was the main negative factor contributing to the IPCA (Brazilian consumer price index), helping to offset upward pressures from other groups, such as food.
Why does electricity have such a significant impact on inflation?
The influence of electricity bills on the IPCA (Brazilian Consumer Price Index) is mainly related to the share of electricity in the household consumption basket and the difficulty of replacing this expense in the short term.
Residential electricity represents approximately 4% of the consumption basket considered by IBGE (Brazilian Institute of Geography and Statistics), ranking among the individual items with the greatest weight in the inflation calculation.
Furthermore, unlike other products whose consumption can be more easily replaced or reduced, electricity is essential for the functioning of homes. Even with tariff increases, families have little room to eliminate this expense.
Another factor is the concentration of tariff adjustments and changes. Changes in the tariff flags, revisions to distributor tariffs, and extraordinary credits can cause variations in the bills of millions of consumers at the same time.
Therefore, electricity can act as both a source of inflationary pressure and a factor of relief. When rates rise, the impact is felt in household budgets and economic indicators. When they fall, they help reduce pressure on prices.
