Monetary base remains elevated after a late-2025 expansion
The monetary base measures the stock of high-powered money in the economy, including currency in circulation and bank reserves held at the central bank. It is a core monetary indicator because it represents the foundation upon which broader money and credit aggregates can expand. Changes in the monetary base can influence liquidity conditions, financial intermediation, inflation dynamics, and the transmission of monetary policy.
Recent dynamics
Mexico’s monetary base moved within a relatively narrow range during the first half of 2025. After starting near 3.28 trillion pesos in January, the series softened through February and then stabilized around the 3.23–3.28 trillion range during March, April, May, and June. This period suggested that base-money growth was contained, even though daily movements remained visible.
From the third quarter onward, the series began to strengthen more clearly. The monetary base moved above 3.29 trillion pesos in July and September, then accelerated more visibly in November and December. By the end of 2025, it had reached approximately 3.54 trillion pesos, marking a substantial increase compared with mid-year levels.
In early 2026, the monetary base remained elevated but uneven. It started the year around 3.55 trillion pesos, declined through February, recovered in March and April, and then strengthened again in May. The latest reading, 3.53 trillion pesos in early June 2026, remains meaningfully above the level observed one year earlier, indicating a continued expansion in the base-money stock.
Interpretation and economic signal
The current signal from the monetary base is expansionary. Although the series has fluctuated during 2026, the level remains clearly higher than in the same period of 2025. This indicates that high-powered money has grown over the past year, even as Banxico has maintained a relatively restrictive policy stance through elevated interest rates.
This distinction is important. A high policy rate can restrain credit demand and broader monetary expansion, but the monetary base can still rise due to currency demand, banking-system liquidity needs, seasonal factors, and central-bank balance-sheet operations. For inflation analysis, the key question is whether this base-money expansion translates into broader money growth, stronger credit creation, or renewed demand-side price pressure.
From an Austrian perspective, the monetary base deserves close attention because it sits near the root of the credit structure. A sustained increase in base money can support financial liquidity, but if it ultimately feeds credit expansion beyond real savings, it can distort relative prices, encourage malinvestment, and delay necessary adjustments in the structure of production.
Overall, the data point to an expanding monetary base rather than monetary contraction. This does not automatically imply immediate inflation acceleration, but it does suggest that Mexico’s monetary backdrop remains liquid. The inflationary relevance will depend on whether base-money growth is absorbed by money demand or transmitted into broader monetary aggregates and credit conditions.
Conclusion
Mexico’s monetary base remains elevated, with the latest reading near 3.53 trillion pesos in early June 2026. This is significantly above the level observed one year earlier, reflecting an expansion in high-powered money over the period.
The current signal is one of expanding monetary liquidity. While short-term fluctuations are normal in a daily monetary series, the broader annual increase should be monitored alongside inflation, credit growth, money aggregates, and Banxico’s policy-rate path to evaluate whether monetary expansion remains contained or begins to reinforce price pressures.
