Chile Finishes Its Index Overhaul and Hands the Keys to MSCI
Chile's stock market has completed an index overhaul, handing the calculation of its IPSA and IGPA benchmarks to MSCI. The change, effective 1 September 2026, follows a similar shift in Colombia and Peru. The nuam holding company, which owns the stock exchanges of Santiago, Lima, and Bogotá, announced the switch. The IPSA will start with 31 members, and the IGPA with 50, both rebranded as MSCI IPSA and MSCI IGPA.
