Le marché financier mexicain opère sous la surveillance de la Banque du Mexique (Banxico), la banque centrale du pays. L'un de ses outils cruciaux pour maintenir la stabilité des prix et gérer la politique monétaire est le "corto," un mot espagnol signifiant "court." Contrairement à certains autres mécanismes de banques centrales, le corto n'est pas un montant fixe ni un instrument spécifique ; il représente plutôt le montant quotidien en pesos que Banxico retire du marché monétaire local. Cette action apparemment simple a des implications significatives pour la liquidité et les taux d'intérêt au sein de l'économie mexicaine.
Comprendre le Mécanisme :
Le corto fonctionne essentiellement comme un drain de liquidité. Banxico y parvient grâce à diverses opérations d'open market, notamment des accords de pension (repos) où il emprunte temporairement des pesos aux banques commerciales, leur offrant des titres publics en garantie. En augmentant le corto – en retirant effectivement plus de pesos de la circulation – Banxico réduit le montant global de fonds facilement disponibles sur le marché monétaire.
Impact sur la Liquidité et les Taux d'Intérêt :
L'impact du corto est directement lié aux lois de l'offre et de la demande. Un corto plus important diminue l'offre de pesos, tandis que la demande reste relativement constante. Cette rareté de fonds fait grimper le taux d'intérêt interbancaire – le taux auquel les banques se prêtent de l'argent du jour au lendemain. Ce taux interbancaire sert de référence pour les autres taux d'intérêt à court terme de l'économie. Par conséquent, une augmentation du corto conduit généralement à :
Inversement, un corto plus faible augmente la liquidité, rendant les emprunts moins chers et stimulant potentiellement l'activité économique, mais aussi potentiellement alimentant l'inflation.
L'Utilisation Stratégique du Corto par Banxico :
Banxico utilise le corto stratégiquement pour gérer la liquidité en réponse à diverses conditions économiques et objectifs politiques. Par exemple, en période de forte inflation, un corto plus important pourrait être mis en œuvre pour freiner la croissance excessive du crédit. Inversement, lors de ralentissements économiques, un corto plus faible peut être utilisé pour injecter des liquidités et stimuler les prêts. La taille du corto n'est pas annoncée publiquement à l'avance, reflétant son rôle d'outil dynamique pour affiner la politique monétaire.
Conclusion :
Le corto est un instrument subtil mais puissant de la boîte à outils de la politique monétaire de Banxico. Ses ajustements quotidiens reflètent l'évaluation continue de l'économie mexicaine par la banque centrale et son engagement à maintenir la stabilité des prix. Comprendre le fonctionnement et l'impact du corto est crucial pour quiconque cherche à naviguer dans les complexités du marché financier mexicain, car ses fluctuations influencent directement les niveaux des taux d'intérêt et les conditions générales de liquidité. Bien qu'il ne soit pas aussi explicitement visible que les autres annonces de politique de la banque centrale, le corto reste un levier vital pour façonner le paysage économique du Mexique.

Scenario: Imagine you are an economic analyst working for a major Mexican bank. You observe the following data over a two-week period:
Task: Based on your understanding of the "corto" mechanism, explain the likely relationship between Banxico's actions in Week 1 and the observed market changes in Week 2. What are the potential reasons Banxico might have increased the "corto"? Discuss the implications of these actions for the Mexican economy, considering both positive and negative consequences.
Banxico's significant increase in the "corto" during Week 1 (through increased reverse repo operations) directly led to the observed market changes in Week 2. By withdrawing a larger amount of pesos from the money market, Banxico reduced liquidity. This scarcity of funds, in accordance with the laws of supply and demand, caused the interbank lending rate to rise by 0.5%. The higher interest rate, in turn, made borrowing more expensive for banks, resulting in a decrease in the growth of new loans issued.
Potential Reasons for Banxico's Actions: Banxico likely increased the "corto" to combat inflationary pressures. High inflation might have been observed, and Banxico used this tool to curb excessive credit growth. Higher interest rates discourage borrowing and spending, thereby cooling down the economy and reducing inflationary pressures.
Implications for the Mexican Economy:
The overall impact depends on the severity of the inflationary pressures and the effectiveness of the policy in curbing them without significantly harming economic growth. A careful balancing act is needed. It is important to note that these are just some of the potential reasons and implications, and a more detailed analysis would require access to more economic data and context.

Chapter 1: Techniques
The Mexican Corto, as a mechanism for managing liquidity, relies on several key techniques implemented by Banco de México (Banxico). These techniques fall primarily under the umbrella of open market operations.
Reverse Repurchase Agreements (Repos): This is the primary technique. Banxico borrows pesos from commercial banks for a short term, offering government securities as collateral. The interest rate on these repos influences the interbank lending rate. The size of the repos directly determines the amount of the Corto. Variations in the maturity of these repos can also be used to influence the short-term or longer-term interest rate landscape.
Term Deposits: Banxico can also use term deposits to manage liquidity. Banks deposit funds with Banxico for a specified period, receiving interest in return. This is a less frequently used tool compared to repos, but can be employed to manage liquidity in a more targeted and longer-term manner.
Foreign Exchange Interventions: Although less directly related to the Corto itself, Banxico’s foreign exchange operations can indirectly impact liquidity. Purchases or sales of foreign currency can affect the peso supply and thus influence the overall liquidity situation, indirectly influencing the size of the Corto needed.
Quantitative Easing (less common): While not a typical tool for Banxico's Corto management, during periods of extreme economic stress, Banxico could theoretically employ techniques resembling quantitative easing. This would involve injecting liquidity directly into the market, likely counteracting a significantly large Corto. However, this remains outside Banxico's typical practices.
Chapter 2: Models
Precisely modeling the impact of the Corto on interest rates and liquidity is complex. Several models, incorporating varying degrees of sophistication, can be applied:
Simple Money Supply Models: These models focus on the direct relationship between the Corto (representing a reduction in the money supply) and interest rates, assuming a relatively stable demand for money. These models provide a basic understanding of the mechanics but lack the nuance of more complex models.
Liquidity Preference Models: These models incorporate the role of banks’ demand for liquidity. Factors such as anticipated future interest rate movements and regulatory requirements are considered, offering a more realistic representation of the interbank market's reaction to the Corto.
Dynamic Stochastic General Equilibrium (DSGE) Models: These advanced macroeconomic models simulate the entire economy, incorporating the Corto as one factor influencing variables like inflation, output, and interest rates. DSGE models offer the most comprehensive analysis but require significant data and computational resources. They are less commonly used for day-to-day Corto analysis due to their complexity.
Vector Autoregression (VAR) Models: These statistical models analyze the relationships between multiple time series, including the Corto, interest rates, and other macroeconomic indicators. They can be used to forecast the impact of changes in the Corto on other variables and to identify potential spillover effects.
Chapter 3: Software
Analyzing and forecasting the effects of the Corto requires specialized software:
Statistical Packages: Software like R, Stata, and EViews are crucial for econometric analysis, including time-series modeling (VAR models) and other statistical techniques used to understand the Corto's impact.
Spreadsheet Software: Microsoft Excel or Google Sheets can be used for basic data analysis and visualization. However, for advanced analysis, specialized statistical software is necessary.
Financial Databases: Access to reliable financial databases (e.g., Bloomberg Terminal, Refinitiv Eikon) is essential for obtaining the necessary data on interbank rates, government securities, and other macroeconomic indicators. These databases often have built-in analytical tools.
Custom-Built Models: Large financial institutions may develop proprietary software and models to simulate the impact of the Corto specifically tailored to their needs. These models are typically highly complex and incorporate a wide range of factors.
Chapter 4: Best Practices
Effective management of the Corto requires adherence to certain best practices:
Transparency (within limitations): While the exact size of the Corto is not publicly announced beforehand, maintaining transparency in the overall monetary policy strategy enhances market confidence. Regular communication of Banxico’s policy goals and rationale behind liquidity management decisions helps reduce uncertainty.
Data-Driven Decisions: The use of robust data analysis techniques and sophisticated models is essential to inform decisions regarding the size and timing of the Corto. Regular monitoring of macroeconomic indicators and market sentiment is crucial.
Adaptive Approach: The Corto should be managed adaptively, adjusting to changing economic circumstances. A rigid approach can be ineffective and potentially harmful.
Coordination with other policies: Banxico should coordinate its Corto strategy with other monetary policy instruments and fiscal policies to ensure a consistent and effective overall policy response.
Contingency Planning: Having contingency plans to handle unexpected shocks and market disruptions is vital. This could involve pre-defined responses to various scenarios.
Chapter 5: Case Studies
Analyzing past instances where Banxico adjusted the Corto allows for a better understanding of its application:
Case Study 1 (Hypothetical Example - High Inflation): During a period of high inflation (e.g., late 1990s or early 2000s, referencing specific years and data would be ideal), Banxico significantly increased the Corto to drain liquidity, raise interest rates, and curb inflation. This case study could analyze the effectiveness of the strategy, examining the impact on inflation, interest rates, and economic growth. Data on the specific Corto size, interest rate movements, and inflation figures would be crucial.
Case Study 2 (Hypothetical Example - Economic Downturn): Conversely, during a period of economic recession (e.g., the 2008 global financial crisis, again, requiring specific dates and data), Banxico might have decreased the Corto to inject liquidity, lower interest rates, and stimulate the economy. Analysis would focus on the effectiveness of this strategy in alleviating the economic downturn and avoiding deflationary pressures.
Case Study 3 (Future Scenario): This could explore a projected scenario, such as a sudden increase in capital flight. Analyzing how Banxico might react with an adjustment to the Corto to mitigate negative consequences would provide a valuable case study, even if hypothetical, helping to understand the tool's possible uses under stress.
These chapters provide a more detailed examination of the Mexican Corto, moving beyond the initial introduction. Note that some sections, particularly the case studies, would benefit from incorporating specific data and referencing actual historical events for a more comprehensive analysis.
