But the maintenance of the interest rate was not the unique determination that took the Colombian Central bank. The other decision taken by the monetary authority and that outside received well by the market, consists of a greater intervention in the exchange market by means of the acquisition of a greater level of dollars through auctions of options put of dollars. Both decisions without doubts will help to contain the evolution of the Colombian peso that had been appraised hard (9.2% in which it goes of the 2008 and a 16.12% in the last 12 months). The appreciation of the type of change worries not only to the Colombian industralists, but also to the government since in the 2007, the deficit of the current account of the balance of payments of Colombia increased to US$ 5,851 million, which represents a 3.4% of the GIP. The decision of a greater intervention in the exchange market, although well it was received by the market, is necessary to recognize that entails its risks What negative aspect can be found him to the decision of a more active policy in the containment of the appreciation of the Colombian weight in front of the dollar? That like the weakness of the dollar at level world-wide it is generating inflation in the prices of the commodities (that when quoting in the North American currency, are worth more and more in terms of this currency although not as much in real terms), which moves to the internal prices of the Latin American economies, restraining the appreciation of the Colombian currency with respect to the dollar, can be increasing this aspect of the inflation. Then if for example the prices of the commodities are increased in a 10% and the relation between the Colombian peso and the dollar stays constant, it moves automatically to the prices. Until the moment, the strong appreciation of the Colombian currency had served to compensate the growth of the prices in dollars. .
