BILATERAL RELATIONSHIP

Brazil and Argentina

Brazil and Argentina have productive and institutional integration that is particularly evident in the automotive industry and Mercosur. Trade connects businesses and employment on both sides of the border. Energy cooperation adds another dimension to the relationship, although infrastructure agreements and studies must be distinguished from flows already in operation.

Definitions and sources

Trade adds both directions. Shares refer to the country’s total goods exports; investment is an accumulated stock, not an annual flow. Every figure retains the currency and period of its source. BEA positions are historical-cost estimates based on the immediate counterpart, not market values or investment by ultimate owner. ‘More than’ indicates a lower bound, not an exact amount. A recorded stock does not establish new activity or authorisation to operate under sanctions.

Definitions, dates and sources

Blank cells are not zero. Average annual inflation and the latest year-on-year figure appear in separate rows: they are not the same measure. Every annual indicator retains its reference year; when the years differ, the figures are identified as not directly comparable. When a figure is unavailable from the World Bank, an annual IMF estimate is used and identified as such. The latest year-on-year figure is the latest official release verified as of 7 October 2026. This includes advance releases marked as provisional. Mexico may have a fortnightly figure before the full month is published; it is not automatically compared with a monthly figure. The publication date is retained in each source’s details; it does not replace the observation period or the annual average. Policy rates carry their own dates and represent different instruments. Spain and France share the ECB rate. Balances are positive for surpluses and negative for deficits. The IMF may use fiscal years; unemployment retains each source’s definition (ILO estimates, IMF WEO or PCBS), as stated in the details. For Palestine, debt and the fiscal balance cover central government and retain the PCBS definition; they are not presented as consolidated general government. These are economic magnitudes, not measures of relationship quality.

Area retains each source’s territorial coverage; it does not determine sovereignty or effective control. Canada uses an archived national geographic reference. Military expenditure retains the 2024 SIPRI sample distributed by the World Bank: the amount and percentage of GDP use that same definition, which differs from NATO’s. It is not an approved budget or a 2026 figure. Information from the Stockholm International Peace Research Institute (SIPRI). Military expenditure database · Terms of use0

What each figure measures

Residents are counted by nationality and the coverage of the stated register, not as people born in the other country or as new arrivals in one year. PERE includes dual nationals and people born outside Spain. Study with OPT and stays carrying academic credit are different measures. Travel may include several visits by the same person; FRONTUR arrivals require an overnight stay, whereas the Canadian survey includes day visits. These figures are neither added together nor automatically compared across directions.

Underlying ties

History, institutions and long-standing issues.

From bilateral agreements to Mercosur

Economic Complementation Agreement No. 14, signed in December 1990, prepared the conditions for bilateral integration. The Treaty of Asunción established Mercosur in 1991, together with Paraguay and Uruguay. Cooperation between Brazil and Argentina therefore has mechanisms that outlast a meeting or a presidential term. Their operation also depends on sectoral and administrative rules: membership of the bloc does not mean that all trade is free of specific conditions. [1]

The automotive production chain has its own rules

Automotive trade is regulated by ACE 14 protocols. Siscomex describes the flex mechanism and rules of origin, as well as instruments for technical convergence. An integrated industrial chain can send vehicles or components in both directions; treating it simply as a list of finished products is insufficient. Updating a protocol affects access and certification conditions, but does not by itself demonstrate new investment or an increase in production already achieved. [1]

What Argentina's figures for 2025 show

INDEC reports Argentine exports to Brazil of 12,771 million USD and imports from Brazil of 18,424 million in 2025. A single statistical reporting basis is retained to add up trade; it is not mixed with Brazilian mirror figures, which may differ because of valuation and recording. The trade balance is the difference between these flows, not a measure of business profits, total employment or the political desirability of the relationship for either country. [3]

Recent developments

Recent developments and latest available data · Reviewed: 2026-10-07

The regime's update in 2025

Additional Protocol No. 46 was incorporated into Brazilian regulations in June 2025, with adjustments to nomenclature and origin requirements. Siscomex also describes the timetable for the flex mechanism: gradual increases and free trade in the covered automotive products from July 2029. This is a date specified in the regime, not liberalisation already applied in 2026. Vehicles, trucks, buses and components therefore depend on specific rules within regional integration. [1]

Natural gas: agreements and studies versus actual deliveries

Brazil's Ministry of Mines and Energy publishes a memorandum on natural-gas marketing and a bilateral working-group report available in April 2026. These documents place interconnection and infrastructure on the economic agenda. A study identifies options and needs; it does not establish that a route is complete, all contracts are signed or an export volume has been achieved. Actual deliveries require their own records. [2]
