Brazil's government announced on October 9 that it is scrapping federal taxes on gasoline imports and sales for 30 days, extending the ethanol tax exemption and adding a diesel import subsidy, just over two weeks before the October 25 presidential runoff. President Luiz Inácio Lula da Silva, seeking a fourth non-consecutive term, faces Senator Flavio Bolsonaro (son of former president Jair Bolsonaro), who led the first round by about 2 million votes. The measures respond to oil price spikes since the Iran war disrupted shipping through the Strait of Hormuz, and aim to keep fuel supply steady and head off the kind of truckers' strike that drove up food prices in 2018.
