Latin America petrol prices — subsidies, inflation, and the peso effect

The price landscape

Latin America produces roughly 8 million barrels of oil per day — about 8 % of world supply — yet its residents experience wildly different pump prices depending on which side of a border they fill up. The table below gives a snapshot of retail petrol prices in mid-2024 in US dollar per litre equivalents, sourced from the OpenVan dataset and cross-checked with IEA World Energy Prices.

The spread is not just about crude: it reflects the fiscal capacity of governments, the political durability of subsidies, and the degree to which exchange-rate moves pass through to consumers.

State oil companies as price-setters

In most of the region, a national oil company — PEMEX in Mexico, Petrobras in Brazil, PDVSA in Venezuela, YPFB in Bolivia, Ecopetrol in Colombia, ANCAP in Uruguay — sits at the centre of the pricing chain. These companies refine and distribute domestically, and governments frequently use them as tools of price management.

Petrobras and the PPI experiment. Brazil's Petrobras adopted an international price parity policy in 2016 under pressure from international investors who were tired of the company selling fuel below market costs. The policy linked refinery gate prices to a mix of Brent crude and the USD/BRL exchange rate. When Russia's invasion of Ukraine sent crude above USD 120/bbl in 2022, Brazilian pump prices jumped 30–40 % within months — triggering a political crisis that led President Lula to pressure Petrobras to moderate increases after his 2023 inauguration. The ANP (National Petroleum Agency) tracks Brazilian fuel prices weekly.

Mexico's IEPS mechanism. Mexico uses its Impuesto Especial sobre Producción y Servicios (IEPS), a special production-and-services tax, as a two-way valve. When international prices are low the IEPS collects revenue; when prices spike, the rate turns negative — effectively a subsidy that caps pump prices. In 2022 alone the foregone IEPS revenue cost Mexico an estimated USD 9 billion, according to IMF fiscal monitor data. PEMEX publishes weekly reference prices through its investor relations portal.

The currency and inflation effect

Because crude is priced in US dollars on international markets, currency weakness directly amplifies import costs in local terms. Latin America has suffered more currency crises than any other region since 1980 — Argentina's peso has devalued over 99 % in the past decade — which means the USD/local-currency rate is often the dominant short-run driver of pump prices in countries that import fuel or price it at import parity.

Chile's MEPCO (Mecanismo de Estabilización de Precios de los Combustibles) is one of the more transparent attempts to smooth this through. It works as a revolving fund: when wholesale prices exceed a reference band, the fund subsidises the difference; when prices fall below the band, importers pay a levy that refills it. The CNE (Comisión Nacional de Energía) publishes the fund balance weekly. The mechanism dampens volatility but cannot offset a sustained depreciation of the CLP against the dollar.

Argentina presents an extreme case. The government has maintained multiple official exchange rates alongside a parallel (informal) rate, making it practically impossible to express a "real" fuel price. Official pump prices have been held below import parity for most of 2022–2024 while inflation ran above 200 % annually, creating a growing fiscal subsidy burden that the IMF's Article IV consultations have repeatedly flagged as unsustainable.

Subsidy reform and its limits

The IMF's 2023 fossil fuel subsidy report estimates that Latin America and the Caribbean spent roughly USD 100 billion annually on explicit and implicit fuel subsidies in recent years — about 1.5 % of regional GDP. The political economy of reform is deeply unfavourable: fuel subsidies disproportionately benefit car-owning middle classes but are presented as pro-poor policies, and any price shock after a subsidy removal generates protests.

Ecuador provides a case study in failed reform. The government of President Moreno attempted to end fuel subsidies in October 2019 after an IMF loan agreement. Eleven days of Indigenous-led protests forced a reversal. A second attempt in 2023 under President Noboa met similar resistance. Ecuador's current subsidy system distinguishes between "regular" fuel (subsidised) and "extra" premium (partly market-linked), but enforcement is weak and cross-border smuggling into Colombia and Peru bleeds the subsidy budget — an echo of the dynamics explored in our Africa fuel smuggling article.

Colombia's approach has been more gradual: the Fondo de Estabilización de Precios de los Combustibles (FEPC) accumulated large deficits when the government held prices below international parity during the 2022 spike. The Petro government has slowly raised pump prices from 2023 onward to close the gap, targeting convergence with import parity by 2026, but the process is politically sensitive given Colombia's fuel import dependency — see our fuel subsidy glossary entry for more context.

Outlook

Several forces are reshaping Latin America's fuel price landscape heading into the late 2020s. Brazil's Petrobras pre-salt deepwater output keeps growing, providing a domestic crude cushion that limits import exposure. Mexico's PEMEX is in structural decline — output fell from 3.4 mb/d in 2004 to under 1.7 mb/d by 2024 — making the country a net petroleum product importer for most grades, which will make the IEPS mechanism increasingly expensive to operate during price spikes.

The energy transition adds a new dimension. Brazil already runs over 40 % of its light vehicle fleet on flex-fuel engines capable of using E27 or higher ethanol blends, which partly insulates consumers from crude oil price shocks — see our article on EV charging costs vs. petrol for the electrification side of the same equation. Chile, Colombia, and Uruguay have aggressive renewable electricity targets that could shift transport economics within a decade, but liquid fuel subsidies will remain politically dominant in the near term.
