Introduction to Banco de México and Its Current Situation

Banco de México, the country’s central bank, has been relentlessly focused on reducing the interbank interest rate. This stance was recently highlighted by Victoria Rodríguez Ceja, the bank’s governor, during the release of the 2025 Financial Stability Report. However, recent developments suggest that this obsession might need reevaluation.

Inflation Trends and Global Context

Rodríguez Ceja emphasized that inflation is near the historical average for 2003-2019, with sub-4% underlying inflation for eight consecutive months. She also acknowledged that the current inflation levels indicate an end to the inflationary episode triggered by global shocks. Nevertheless, the recent quinzenal inflation jump from 4.22% to 4.62% in May contradicts her assertion of stable inflation around the historical average.

Moreover, the governor’s underestimation of margin analysis—which indicates a growing price increase in May—contradicts her confidence in the bank’s assessment of the uncertain global environment. The ongoing Middle East tensions, particularly the Israel-Iran conflict, have increased oil price volatility. This volatility could lead to greater variability in inflation rates, especially if Iran decides to block the Strait of Hormuz, through which nearly 20 million barrels of crude oil are transported daily—approximately one-third of the globally traded oil.

Recommendations for Banco de México

Given the international context, Banco de México should adopt a cautious approach to interest rate adjustments. The governor should avoid hastily lowering the interbank interest rate further, especially in the upcoming decision on June 26. More importantly, the bank must reassess its communication strategy regarding monetary policy decisions, as its credibility and good reputation are eroding.

For a central bank, consistently defining achievable policy objectives and communicating them effectively builds credibility, ensuring that monetary policy decisions are trusted and effective. However, when economic agents begin to doubt the central bank’s inflation expectations communication, it negatively impacts the perception of decisions and their timeliness.

Mexico’s Vulnerability to Central Bank Credibility Loss

Mexico cannot afford to squander the credibility Banco de México has built over the years. The bank’s credibility should not be compromised by catering to the Mexican government’s need for growth projections.
