Banxico expands liquidity tools with government bond purchases
Banco de México will now be able to purchase government securities to manage market liquidity more permanently. New regulations, effective August 17, 2026, complement existing tools for monetary regulation.
Expanding the liquidity toolkit
Banco de México has introduced new operational capabilities to manage liquidity in the financial system.
Circular 8/2026, issued on June 15, 2026, amends Circular 6/2012 to allow the central bank to purchase government securities, specifically CETES and Bondes F. Previously, Circular 6/2012 only regulated the sale of such securities.
These new operations, set to take effect on August 17, 2026, aim to complement Banxico's existing short-term Open Market Operations (OMAs) by providing a more permanent mechanism to address liquidity shortfalls.
The central bank's primary objective is to maintain the overnight interbank interest rate as close as possible to its target, currently set at 6.5 percent, by actively managing liquidity surpluses and deficits in the market.
Targeted liquidity, not quantitative easing
These new purchase operations are distinctly different from quantitative easing (QE) or yield curve control programs.
Unlike QE, which aims to create abundant liquidity and often involves buying long-term, fixed-rate securities to lower their yields, Banxico's operations are designed solely to provide the necessary liquidity for the money market to function properly.
By focusing on variable-rate Bondes F and short-term CETES, the central bank explicitly avoids impacting long-term fixed-rate bond yields.
The sole purpose is to facilitate the implementation of the Governing Board's monetary policy stance by managing liquidity, rather than to relax monetary conditions once the policy rate reaches its effective lower bound.
Precision over broad impact
Banxico gains crucial flexibility in managing liquidity shortfalls more permanently.
This technical refinement reinforces its commitment to the policy rate target, explicitly avoiding any quantitative easing interpretation.
The move signals operational efficiency, not a shift in monetary policy stance.
