Preço do diesel no Brasil subiu mais de 20% desde o início da guerra no Irã | CNN Brasil
Segundo levantamento da CNN, com base em dados da ANP, esse é o maior valor médio do combustível desde agosto de 2022
De acordo com um levantamentodo CNN Money com base em dados da ANP (Agência Nacional de Petróleo, Gás Natural e Biocombustíveis), o preço médio do diesel comum no Brasil cresceu 20,39% desde o início dos conlfitos no Oriente Médio, há três semanas.
Na semana do dia 28 de fevereiro, primeiro dia do conflito, o preço médio do combustível foi verificado em R$ 6,03. Agora, nesta semana, o boletim da ANP registrou o valor médio do diesel comum em R$ 7,26, com uma alta de R$ 1,23.
Vale pontuar ainda que nas semanas anteriores ao início do conflito, o preço do combustível vinha registrando queda e depois uma estabilidade, na casa dos R$ 6.
O diesel S10, versão mais limpa do combustível, teve um crescimento similar, de 20,29%. Na semana de início do conflito, o valor médio do combustível no país era de R$ 6,11. Agora, segundo o levantamento desta semana da ANP, o preço chegou a R$ 7,35.
Ainda segundo a série histórica da ANP, esse é o maior valor registrado do combustível no governo Lula (PT). A última vez que o diesel chegou neste patamar foi na primeira semana de agosto de 2022, quando o preço médio registrado foi de R$ 7,37.
Nessa época, o diesel vinha registrando queda, mesmo em patamares elevados, pois estava sendo impactado pela lei complementar aprovada no Congresso que limitou o ICMS sobre combustíveis.
É importante ressaltar que o diesel é o principal combustível do país pelo uso na indústria e no modal rodoviário, principal meio de transporte de passageiros e de carga utilizado no Brasil. Dessa forma, um aumento no preço deste combustível impacta toda a cadeia de consumo.

"subiu mais de 20% desde o início da guerra no Irã"
The article strongly implies the conflict is the cause of the price increase but does not provide evidence directly linking global market mechanics to the specific 20% rise.
Unsupported cause"Brasil subiu mais de 20% desde o início da guerra no Irã Segundo levantamento da CNN, com base em dados da A"
The article presents a temporal correlation (price increase started with conflict) as a direct causal relationship without providing evidence of the market mechanisms (e.g., oil price fluctuations, supply chain disruptions) that link the Middle East conflict to Brazilian diesel prices.
