The new pricing system scraps a so-called fuel import parity policy that more closely aligned prices at the pump with the oil market and exchange rates. In a research note, JPMorgan (JPM.N) described the reworked pricing policy as "more friendly than investors expected." The policy shift will be tested when oil prices rise, and apply upward pressure on what consumers can expect to pay for motor fuels or LPG. Petrobras' new pricing policy also came under criticism from some as too opaque. The previous pricing policy was adopted seven years ago by conservative former President Michel Temer.
