Chile fuel price surge; Mepco tweak saves Treasury $2B

Chilean gasoline and diesel prices rose sharply in September, with 93/97 octane up 35 pesos/L and diesel up 89 pesos/L, pressuring transport. The government modified the Fuel Price Stabilization Mechanism (Mepco), reportedly saving the Treasury $2 billion, though the mechanism's long-term fiscal sustainability remains uncertain. This affects inflation and transport costs in Chile.
