The 10 Largest Family Businesses in Buenos Aires

Buenos Aires at Night

Argentina is Latin America’s third largest economy, with a GDP of around $632 billion. A resource-rich nation, Argentina controls the world’s second-largest shale gas and fourth-largest shale oil reserves. The production of unconventional oil and gas has been one of the country’s fastest-growing sectors, up around 26% from 2022. Despite the rise in oil and gas production, agriculture remains Argentina’s leading supply category, accounting for approximately 55% of its total exports.   

Buenos Aires is Argentina’s trade centre, manufacturing base, and financial hub. The country’s capital city accounts for about 15% of Argentina’s GDP, generating around $95 billion annually. Buenos Aires is home to South America’s second largest tech start-up sector, behind Brazil’s São Paulo. Despite a complicated business environment, growing inflation, and uncertainty around the value of the country’s peso, Argentina’s private sector plays a vital role in the country’s economic performance, accounting for 29% of the nation’s total employment.
