The BSP, however, is "closely monitoring developments affecting the peso and it stands prepared to use the tools available to it as the need arises," he said in a statement.
Buenaventura said he met President Arroyo and her key economic advisers over the weekend to brief her on "developments relating to the movement of the peso" after Mrs. Arroyo expressed concern over the currency’s decline.
"We remain convinced that this is a temporary blip and that the peso should stabilize once the political scenario becomes clearer," Buenaventura said.
The central bank will meantime closely monitor foreign exchange transactions of banks, he added.
Presidential Spokesman Ignacio Bunye said Mrs. Arroyo believes the country’s economic fundamentals remained sound and that economic prospects for the year remain on track.
"There should be no cause for panic," Bunye told reporters. "Things will improve and that’s the general forecast."
Buenaventura blamed the peso’s drop to political jitters "caused by fears of the unknown" ahead of the May 10 presidential election.

Buenaventura warned local banks they should comply with regulations and not take advantage of the political uncertainty.
Mrs. Arroyo earlier warned that efforts to revitalize the nation’s struggling economy might be derailed if the next president does not have the required experience to run the country.
