Socioeconomic Planning Secretary Dante Canlas said the relative calm in commodity prices was due mainly to the stability in domestic food supply which ensured that prices would not be aggravated by disruptions in the supply chain.
"The relative stability of the agriculture sector has a lot to do with this," Canlas said. "But even if we had problems with domestic supply, we have liberalized imports to such an extent that it would not be a problem," he added.
Canlas said average inflation for the year was likely to be around six percent. "Very close to six. I think just slightly over six percent.. if we hit four in December, and I think we will," he said.
