Key Facts
—The move. Mexico’s central bank has given itself the power to buy short-term government bonds in the open market, a tool it did not have before.
—The date. The power was created by Circular 8/2026, published on June 15, announced on June 29, and switches on August 17, 2026.
—The limits. It covers only Cetes, the short-term Treasury bill, and Bondes F, a floating-rate note, and deliberately leaves longer fixed-rate bonds untouched.
—The ceiling. Analysts at Finamex read the cap at one hundred billion pesos ($5.3 billion) a quarter, useful but modest against the stock of government paper.
