The aim of this article is to examine the scopes and the convenience of the last agreement proposed by the committee of central banks (Committee of Basle). In which there were established different mechanisms that try to improve the procedure and rules proposed by his predecessor (Basle the IInd), and that tries to reinforce in outline the reservations of cash and another type of the capital in the banks to act opposite to eventual emergencies. Then it was centring on the attention on the relevancy of the new procedure and the need of the recent version of the Basilea departing from the responsibility of the financial system in the current crisis. Since though consensus exists almost world what on the irresponsible behavior of the systematicly important banks, recognizes equally that partly the financial crisis, it is consequence of the bad regulation and supervision of the financial authorities. Finally there is done a sketch of the repercussions of these procedure in emergent countries of Latin America.
