What it provokes the inflation? In the vision of liberal economy, the state is propeller of the inflation when offering a monetary base above of the expectation between offers and demand. In the vision of the keynesiana economy, the inflation is generated by the level of speculation on the currency and mechanisms of defenses are set in motion, as control on capitals to eliminate the origin of this disequilibrium between real and monetary economy. A thing does not exist doubt between the two vises. The Central banking is who prints currency and in such a way the state is monopolista in the money creation. Soon it is the owner of the key of the safe. If he will have money excessively circulating is because the safe was opened some times and if this safe will be inactive, the economy will answer the currency in circulation in accordance with, reducing the levels of prices of the real merchandises. To cite an example, a good imagines that costs today in economy R$ 1,00.

Another data are that this good depreciates in 9,7% to the year. After five years it will be valid R$ 0,63. The monetary base it was not modified and the good is depreciated in agreement the time. The real measure of value that this good acquired was in the act of its conception and the moment that it was being useful for consumption, either for companies or families. This is the real economy without currency that speculates on the actual values. Now let us place in the example a Central banking that emits currencies and, as consequncia of its acts, stipulates a tax ' ' aceitvel' ' of inflation to the year in 4,5%. Then, the currency raises its offers in the economy and the good that costs R$ 1,00 starts to be valid, after five years, R$ 1,25.
