The Ibovespa, the main index of the Brazilian stock exchange, closed at a high of 4.85%, at 74,617.24 points, after falling 14% the day before. The commercial dollar closed down 0.88%, sold at R$ 5.002. Dollar jumped 4.86%, to R$ 5.0467 on the sale, which was a new maximum record high for a close. To try to contain the dollar’s rise, the Central Bank offered $ 2 billion through line auctions. A similar measure had been taken on Friday, the first time that the BC has made a net money supply in this modality since December 18 of last year. Line auctions are usually held at times of punctual demand for liquidity.
