Brazil’s Oil Exports to China Double in Q1 2026 as Hormuz Rewires Flow

Every Iran war crisis produces winners. The Q1 2026 trade data confirms that Brazil is one of them—but only because Petrobras, the pre-salt basin, and a decade-plus of Chinese state-enterprise investment had already positioned the country to capture the flow.

The Brazil oil exports China surge in the first quarter of 2026 produced the largest Q1 bilateral trade figure ever recorded and marks a definitive shift in how China is sourcing crude during the Iran war. The Rio Times, the Latin American financial news outlet, reports that Brazilian oil shipments to China roughly doubled year-over-year to US$7.19 billion in Q1 alone, according to the Conselho Empresarial Brasil-China (CEBC), driving total bilateral exports to US$23.9 billion and cementing China’s position as the destination for more than half of Brazil’s crude output.

The Hormuz Redirect

Since the US-Israel war against Iran began, the Strait of Hormuz—the chokepoint through which roughly 20% of global oil flows—has operated under sustained threat. March 2026 saw Brent spike above US$92 per barrel before Trump’s brief two-week ceasefire announcement briefly pulled prices back to US$94 (from US$107 highs); Goldman Sachs projects Brent averaging above US$100 through 2026 if Hormuz remains closed another month. Chinese refiners responded by shifting orders to non-Middle East suppliers with the volume to scale quickly.

Túlio Cariello, CEBC’s director of content and research, framed it directly: “With the question in Iran and above all the instability in the Strait of Hormuz—an important route—the Chinese started to seek other reliable suppliers, and Brazil is a country with large oil supply and Chinese companies already operating here for a long time.” The scale of the shift is striking: China now absorbs 57% of all Brazilian crude exports by value and, in March alone, 65%. The 1.6 million barrels per day figure for March 2026 is the second-highest monthly shipment volume in Brazilian history.

Why This Was Already Happening Before the War

The Hormuz redirect is amplifying a structural trend that began before the war: in 2025, Brazilian oil exports to China hit record volumes of 44 million tons and record value of US$20 billion, representing 45% of all Brazilian crude exports and 4.5 times the volume sent to the United States in second place. Chinese state-owned oil companies CNPC and CNOOC have been part of Brazil’s pre-salt exploration since before Brazil became a net oil exporter. CNPC was among the winners in the June 2025 auction that included Equatorial Margin blocks—the frontier zone between Amapá and Rio Grande do Norte states.

Roberto Ardenghy, president of the Brazilian Petroleum and Gas Institute, identified the opportunity and the risk in the same observation: “The relationship with China is fundamental and will continue to be, but Brazil’s challenge is to reduce dependence on commodities and expand insertion in more sophisticated value chains.” The 2025 full-year bilateral trade flow reached a record US$171 billion, more than double Brazil’s US$83 billion flow with the United States. Brazil ran a US$29.1 billion surplus with China last year—its seventeenth consecutive year of surplus.

The Electric Vehicle Counter-Flow

While Brazil shipped record crude to China, Chinese electric and hybrid vehicle shipments to Brazil exploded 7.5 times year-over-year to US$1.23 billion in Q1 2026 alone. Anfavea data showed 100,000 electrified vehicles were sold in the Brazilian domestic market in the quarter. Cariello put the market reality bluntly: “The Brazilian is adopting the EV, and today the electric car is synonymous with the Chinese car and vice versa in Brazil.”

The EV import surge was partly a rush to beat tariff changes under Brazil’s Mover automotive-industry program, which had kept lower tariffs on electrified vehicles and parts but is gradually rescheduling them upward to incentivize local production. The January 31 expiration of the CKD and SKD kit import exemption already triggered tensions between Anfavea’s traditional multinational members and new Chinese entrants announcing billion-dollar factory investments in Brazil. Soybeans and iron ore also fell in volume during Q1 but saw slight value gains on higher global prices, Cariello noted.

What This Means for the Real and Brazilian FX Reserves

The record oil flows to China directly reinforce Brazil’s current account and international reserves, contributing to the real’s strength through 2026—even as BC monetary policy director Nilton David warned in Washington that the appreciation is conjunctural, not structural. The deeper question is the one Ardenghy identified: a trade relationship where 75%+ of Brazilian exports to China are three commodities (oil, soybeans, iron ore) and where the return flow is dominated by manufactured goods like EVs produces both surplus dollars today and structural vulnerability tomorrow. For now, the Hormuz disruption is a revenue stream Petrobras did not anticipate at the start of the year—and one that is likely to continue as long as the Iran war and the 1.6 million barrels per day to China hold.
