“The First World, to which we had been repeatedly told we must reach, is crumbling like a bubble”, she underlined. “In the midst of the swelling sea” Argentina remains strong. “It’s time many of those institutions instead of telling us what to do, should look around and do something for themselves”.

Meantime Brazil's stocks rallied on Thursday on optimism about a potential US plan to solve the financial crisis, while the Real tumbled but pared losses after the central bank said it would help ease a liquidity drought.

Sao Paulo's main stock index Bovespa jumped 5.48% with Wall Street to a close at 48,422.75 points -- its biggest daily gain since April. Even so, the stock market is still down more than 24% this year.

Brazil's currency dropped as much as 5%, its biggest daily drop in more than a year, as investors sought liquidity in a dried-up market. But losses eased after the central bank said it would offer dollar repurchase agreements to supply liquidity to the market and closed down 2.89% at 1.921 per dollar.

News that U.S. Treasury Secretary Henry Paulson has been shopping around a proposal to Congress that would create an entity to deal with bad debt boosted Wall Street, and Brazilian stocks with it.

The biggest weighted gainer was government managed oil corporation Petrobras which benefited from higher oil prices. It rose 8.05% to 32.20 Real while mining giant Vale gained 7.45% to 34.60 Real.

Banks also rallied, with Itau, Banco Bradesco and Unibanco up between 6.6 and 8.6%.

However Brazil's Central Bank said robust economic activity continues to pose a significant risk to its goal of achieving benign inflation despite signs of a global slowdown and a decline in commodity prices.
