In the past few months, prices of LPG have risen to an all-time high. According to data reported by the Energy Regulatory Commission (CRE), the average price of liquefied petroleum gas (LPG) in June 2017 was 8.77 pesos ($0.43) per litre, while the average price in June 2021 was 12.94 pesos ($0.64).(1) In light of this, the Federal Economic Competition Commission (COFECE)  launched an ongoing investigation(2) on 31 May 2021 to determine whether effective competition conditions exist in the LPG market. COFECE is also investigating possible anticompetitive behaviour in the market(3) similar to its previous studies, which provided multiple recommendations to promote competition in the market.(4)
