The opening of international markets began marked by caution after a technical stoppage that interrupted the formation of prices in major futures contracts in the United States. The failure occurred in a data center responsible for supporting the systems of the CME, which temporarily suspended trading of indices, currencies, commodities, and bonds. According to TF Agroeconômica, the problem arose around midnight on November 27 and removed the main references from investors before a session that was already scheduled to occur with reduced hours.
