Etherfuse CETES, officially known as Certificados de la Tesorería de la Federación, are Mexico's oldest short-term debt securities issued by the Ministry of Finance. They play crucial roles in the financial system, serving purposes such as government financing, influencing monetary policy, and providing a safe investment option. CETES are BBB- rated short-term government bonds and are highly liquid in the Mexican market. Interest on these bonds accrues until maturity, and their rates are determined through government auctions, which ensures the backing of the Mexican government. All brokerages that Etherfuse works with use the Institute for the Deposit of Securities (Instituto para el Deposito de Valores, or INDEVAL) for safe and secure custody of CETES. This ensures that all holdings and investments are transparent and secure.
