Monetary base remains above year-ago levels despite short-term volatility
Recent dynamics
The monetary base fluctuated within a relatively broad range during 2025. It began the year at approximately CLP 18.84 trillion, increased to CLP 19.47 trillion in March, and then declined sharply to approximately CLP 18.42 trillion in April.
Subsequent movements remained volatile. The monetary base recovered through May and June, declined again in July, and then increased to approximately CLP 19.50 trillion in August. It remained close to CLP 19 trillion through the end of the year.
The level moved generally higher during the first half of 2026. The monetary base reached approximately CLP 19.75 trillion in February and increased to around CLP 19.85 trillion in June, the highest observation in the recent period.
The latest observation declined to approximately CLP 19.33 trillion, reversing part of the preceding increase. Despite this short-term pullback, the monetary base remains about 4.8% above its level one year earlier.
The latest monthly movement therefore contrasts with the annual comparison. Base money declined approximately 2.7% from the previous observation, while remaining clearly higher over a twelve-month horizon.
Interpretation and economic signal
The combination of positive annual growth and a negative latest monthly movement creates a mixed short-term signal. The stock of base money remains elevated relative to one year earlier, but the recent increase in liquidity has partially reversed.
An increase in the monetary base should not automatically be interpreted as a loosening of monetary policy. Base money can change in response to currency demand, banking-system reserve needs, payment flows, and central-bank liquidity-management operations.
In an interest-rate-targeting framework, the monetary policy stance is more directly reflected in the policy rate and broader financial conditions. The monetary base is therefore better treated as a complementary indicator of liquidity rather than as a standalone measure of monetary policy.
The economic importance of changes in base money also depends on their transmission into broader monetary aggregates, bank credit, nominal spending, and inflation. A higher monetary base combined with subdued credit or deposit growth can have a very different macroeconomic effect from an expansion that spreads through the broader financial system.
The latest decline is therefore better interpreted as a short-term moderation from an elevated level than as evidence of a structural contraction in monetary liquidity.
Conclusion
Chile's monetary base remains above its level one year earlier. The latest monthly average stands near CLP 19.3 trillion, with annual growth remaining positive at approximately 4.8%.
Short-term momentum has nevertheless weakened following the previous increase in base money. The latest observation represents a partial reversal rather than a continuation of the earlier upward movement.
The current signal is therefore one of an elevated monetary base accompanied by a short-term pullback. Broader implications depend on whether changes in central-bank liquidity are transmitted into money growth, credit, spending, and inflation.
