BRASILIA, Nov 21 (Reuters) - Brazil's central bank chief, Roberto Campos Neto, said on Tuesday the decisions by some of the country's states to increase the ICMS tax should have an impact on inflation in the range of 10-20 basis points.

Speaking at an event hosted by Arko Advice, he noted the most recent inflation figure showed "good quality," adding there is a "great possibility" the inflation reading ends this year within the government's official target. (Reporting by Marcela Ayres Editing by Chris Reese)
