Should Argentina and Brazil adopt a joint currency?

Updated: Feb 12, 2023


The news of Brazil and Argentina starting preparations for a common currency has recently made headlines and sparked debates among economists and policymakers. This article aims to provide an in-depth analysis of the potential outcomes of such an initiative, considering the economic and financial performance of both countries and their impact on the regional and global economy.

Benefits of a Joint Currency

While there are several potential benefits of a joint currency between Argentina and Brazil, the most notable is the promotion of regional integration and trade. With a common currency, transactions between the two countries would become easier and more streamlined, leading to increased trade flows and economic growth. Furthermore, a joint currency would also eliminate the need for currency conversions and reduce exchange rate risks, thereby fostering economic stability in the region.

Drawbacks of a Joint Currency

However, the implementation of a joint currency is not without its challenges and potential drawbacks. One of the main concerns is the heterogeneity between the two economies, as Argentina and Brazil have different levels of economic development and growth rates. This could result in imbalances in the distribution of benefits and costs, potentially leading to economic instability.

Additionally, a joint currency would also require a high degree of fiscal and monetary coordination between the two countries. This would require the establishment of a common fiscal policy and a shared monetary policy, which could be challenging given the different political and economic systems in place.

Another key concern is the impact on monetary sovereignty. A joint currency would imply a loss of independence in monetary policy and a transfer of control over monetary affairs to a supra-national authority. This could result in a loss of flexibility in responding to economic shocks and imbalances, potentially leading to increased economic instability.

Economic Performance of Argentina and Brazil

To fully understand the potential outcomes of a joint currency, it is important to examine the economic performance of Argentina and Brazil. In recent years, both countries have experienced a significant improvement in their economic and financial performance, with GDP growth rates and inflation levels trending upward.

In light of these economic challenges, it is important to consider the impact of a joint currency on the economic stability and performance of both countries. While a joint currency has the potential to promote economic integration and stability, it could also amplify existing economic imbalances and lead to increased economic instability in the region.


In conclusion, the potential outcome of a joint currency between Argentina and Brazil is complex and multi-faceted. While there are several potential benefits, such as the promotion of regional integration and trade, there are also several potential drawbacks, including the impact on monetary sovereignty, the need for fiscal and monetary coordination, and the potential for economic imbalances.

Therefore, a careful and thorough evaluation of the potential outcomes of a joint currency is necessary before any decisions are made. The success of a joint currency would depend on the ability of both countries to address existing economic challenges and work towards a shared fiscal and monetary policy that promotes stability and growth in the region.
