With an increase of 0.3% in the country's industrial sector in this comparison, seven of the 18 areas presented positive results, with a highlight to Amazonas (13.0%), Maranhão (11.5%) and Minas Gerais (9.8% ).

In the cumulative result for the last 12 months, the industrial sector decreased by 0.2% and seven of the 15 areas surveyed followed the negative result.

In the 0.3% drop of industrial production in January, in the seasonally adjusted series, eight of the 15 areas surveyed showed negative rates. Rio Grande do Sul (-3.4%), São Paulo (-3.1%) and Mato Grosso (-2.0%) registered the sharpest declines, with the first eliminating the advance of 1.9% seen in December 2022; the second intensifying the fall of 0.8% registered in the previous month; and the latter interrupting two consecutive months of expansion in production, a period in which it accumulated gain of 9.3%. Rio de Janeiro (-1.0%), Santa Catarina (-1.0%), Pará (-0.4%), Paraná (-0.3%) and Bahia (-0.2%) completed the set of areas with negative indexes in January 2023.

On the other hand, Espírito Santo (18.6%) and Pernambuco (17.3%) had double-digit expansions and the highest rates in that month, with the former returning to growth after retreating 5.2% in the previous month; and the second eliminating part of the 26.2% loss accumulated in the last four months of 2022.

The quarterly moving average index for industry changed -0.1% in the quarter ended in January compared to the level of the previous month, interrupting the predominantly upward trend started in October 2022. Five of the fifteen areas surveyed showed negative rates in that month, with a highlight to the sharpest decreases registered by Rio de Janeiro (-2.8%) and Pará (-1.8%). On the other hand, Paraná (7.3%), Espírito Santo (6.9%), Pernambuco (4.1%), Ceará (3.1%), Goiás (2.6%), Mato Grosso (2. 3%), Northeast Region (2.2%) and Bahia (1.7%) showed the main advances in January 2023.

Compared to January 2022, domestic industry increased by 0.3% in January 2023, with positive rates in seven of the 18 areas surveyed. It is worth mentioning that January 2023 (22 days) had one more business day than the same month of the previous year (21). In that month, Amazonas (13.0%), Maranhão (11.5%) and Minas Gerais (9.8%) registered the greatest expansions.

The expansion in Amazonas was driven mainly by the activities of other transportation equipment (motorcycles and their parts and accessories), beverages (syrup preparations for industrial purposes for preparing beverages), information technology equipment, electronic and optical products (televisions, video receiver-decoder  and radio signals for motor vehicles) and coke, petroleum products and biofuels (motor gasoline, naphtha and aviation kerosene). In Maranhão, the advance was related to pulp, paper and paper products (cellulose), beverages (beers, draft beer and soft drinks) and food products (bread, cakes and ready-to-eat desserts).

In Minas Gerais, growth was driven by the following activities: mining and quarrying industries (iron ores), coke, petroleum products and biofuels (diesel fuel, motor gasoline and petroleum bitumen) and food products (sausage and other pork meat preparations, frozen poultry meat and offal, roasted and ground coffee, condensed milk and frozen, fresh or cooled beef).

Mato Grosso do Sul (4.5%), Goiás (3.5%) and Rio de Janeiro (3.2%) also showed higher positive rates than the national average (0.3%), while Ceará (0 .2%) completed the set of places with advances in production in the monthly index for January 2023.

On the other hand, Mato Grosso (-14.6%), Rio Grande do Norte (-10.5%) and Bahia (-10.3%) had the most intense decreases in this comparison. Rio Grande do Sul (-7.7%), Espírito Santo (-6.5%), Northeast Region (-5.3%), Santa Catarina (-4.9%), Pará (-4.6%) , Pernambuco (-2.8%), São Paulo (-2.1%) and Paraná (-0.4%) showed the other negative results in that month.

The cumulative index in the last 12 months, having changed -0.2% in January 2023, reduced the intensity of loss compared to that recorded in the months of December (-0.7%), November (-1.1%), October ( -1.5%), September (-2.3%), August (-2.6%) and July (-2.8%) of 2022. In regional terms, seven of the fifteen areas surveyed recorded negative rates in January of 2023, but nine showed greater dynamism compared to the December 2022 indices. Ceará (from -4.9% to -2.9%), Pará (from -9.1% to -7.5%), Minas Gerais (from -1.3% to 0.1%) and Amazonas (from 3.8% to 5.1%) showed the main gains between December 2022 and January 2023, while Mato Grosso (from 19.4% to 13.7%), Espírito Santo (from -8.4% to -9.7%) and Goiás (from 1.4% to 0.4%) registered the greatest losses between the two periods.
