Background on Certificados de la Tesorería de la Federación (Cetes)

The Certificados de la Tesorería de la Federación (Cetes) are short-term Mexican government bonds issued by the Mexican Treasury to raise funds in the domestic market. These securities are considered a safe investment option for individuals and institutions, as they are backed by the Mexican government. Banco de México (Mexico’s central bank) sets the interest rates for Cetes, which influence short-term interest rates in Mexico.

This represents a decrease of 30 basis points from the previous week, and the amount placed was 7,000 million pesos, with demand being 3.07 times the offered amount.

Yearly Trends

So far this year, the 28-day Cetes yield has decreased by 264 basis points, aligning with the downward cycle of the reference rate set by the central bank. This trend indicates a continuous effort to stimulate economic growth through lower borrowing costs.
