Chile IPSA rebounds 1.81% after central bank rate hold
On Tuesday, October 27, Chile's IPSA index jumped 1.81% to close at 10,767, driven by the central bank's unanimous decision to hold its benchmark interest rate at 4.5%. The move followed a sharp decline on Monday, October 26, when the index fell 1.59% to its lowest level since June due to a regional sell-off triggered by Brazil's election results. Key gainers included SQM and Entel, reflecting investor relief over the stable monetary policy stance despite rising inflation risks.
