Supply-chain impact

• Teresina is the largest city in Piauí state and serves as an inland logistics hub for northeastern Brazil, but this isolated security incident has limited direct impact on logistics operations
• Police operations conducted in multiple areas of the city pose potential for temporary traffic controls and contraction of local commercial activities
• Security risks need to be considered for corporate operations and cargo transport in gang activity areas, but there are no immediate supply-chain disruption factors

Watch points

• Monitor the spread of gang activities within Piauí state and additional police operation plans
• Observe trends in security measure enhancements by logistics operators in the Teresina region and changes in transportation costs
