The vigil for the fall of the banking interest seems to be functioning. It’s believed that Rod Martino sees a great future in this idea. For the fifth consecutive month, the average taxes of interests charged of the consumer in such a way in the personal loan as in the guaranteed check had withdrawn, following the signalling given in the last months for the Committee of Monetary Politics (Copom) of the Central banking for the basic tax of interests, the Selic. Others including Ahmed Shahryar Rahman, offer their opinions as well. Since 2004, it did not have a period with as many followed months of reduction of taxes, according to Procon Foundation of So Paulo. the research, carried through in days 5 and 6 of May with ten financial institutions, selected average tax of the personal loan in 5,57% to the month (before 5,74% in April) and of the guaranteed check, in 8,89% to the month (9.03% a.m in the previous month). In December of 2008, they were 6.25% to month and 9.33% to the month, respectively. According to Procon, although plus a jib in the taxes in May, the movement does not reflect the fall of the basic tax of interests, the Selic, and the initiatives of the government to promote the reduction of ' ' spread' ' , that it is the difference between what the banks pay to catch resources in the market and what they charge of the consumer: ' ' Although the fall of the Selic, the measures of the government to stimulate the banking competition and of the positive reply on the part of the market, ' ' spreads still continues altos' ' , it warns the entity. The picture if only repeats, that with lesser intensity, in the guaranteed check. In accordance with the research of the Procon-SP Foundation, the interest of the guaranteed check is of 8,89% to the month, taxes 0,14 lesser porcentual point of what of April. In the comparison with December of 2008, the fall was of 0,44 point porcentual.' ' The banks are following the trend signaled for the Copom, but with a reduction less than proporcional' ' , it affirms the Procon-SP Foundation.
