3 articles · Updated · Bloomberg · Jul 31

Summary

  • Trading in most Brazil assets was suspended Friday after B3 delayed the market open and halted activity across the exchange.
  • B3 said technical issues in processing operations caused the disruption and widespread delays, without giving a timeline for when trading would resume.
  • Brazil’s main exchange effectively holds a monopoly over local trading, making the outage a broad market stoppage rather than an isolated venue problem.
