Introduction In the financial realm, the use of mathematical models has become a fundamental practice for traditional financial institutions. These models not only enable them to understand and anticipate market movements but also play an essential role in strategic decision-making. «Fernández, C., & Labastida, I., 2019» [9]. In the context of the five largest economies in Latin America, the application of mathematical models in the financial sector has experienced significant growth. This article will explore how financial institutions in countries such as Brazil, Mexico, Argentina, Colombia, and Chile employ mathematical models to optimize their operations, manage risks, and adapt to a dynamic economic environment.

The main objective of this article is to provide a comprehensive overview of the mathematical models used by financial institutions in the five major economies of Latin America. Through a detailed analysis, the aim is to examine how these models contribute to strategic decision-making, risk management, and the pursuit of operational efficiency in a highly dynamic financial sector. By highlighting specific examples and emerging trends, the goal is to offer readers a deeper understanding of the influence of mathematical models on the financial landscape of the region.

Methodology

The following is a country-by-country analysisPrincipio del formulario.

Brazil has demonstrated a growing interest in incorporating emerging technologies into the financial sector. Leading banking institutions have implemented mathematical models supported by artificial intelligence to optimize risk management and enhance accuracy in predicting economic trends. AI is also utilized in fraud detection and the personalization of financial services.

In Mexico, financial institutions are actively exploring advanced mathematical models to enhance decision-making. Artificial intelligence and machine learning are applied in credit assessment and portfolio management, enabling greater efficiency in resource allocation and more precise risk management.

Argentina has experienced an increase in the application of AI-backed mathematical models to address economic volatility. AI is used in creating investment strategies and predicting market movements. However, the country's specific economic challenges have influenced the adoption of these technologies.

Colombia has shown progress in adopting emerging technologies in the financial sector. AI-driven mathematical models are applied in portfolio management and the personalization of financial services. Machine learning is used to improve operational efficiency and early risk detection.

In Chile, financial institutions have adopted innovative approaches based on artificial intelligence to enhance asset and liability management. The application of advanced mathematical models contributes to greater accuracy in economic projections and more sophisticated risk management.

In general, the five countries with the largest economies in Latin America are undergoing a shift towards the adoption of emerging technologies in the financial sector. Artificial intelligence and machine learning are used to strengthen decision-making, improve risk management, and optimize operational efficiency. However, variations in adoption speed and specific approaches reflect the different economic and regulatory realities of each country. This analysis highlights the need to consider contextual factors when assessing emerging trends in financial mathematical models in the region.
