JPMorgan is considering reducing the share of India and China in its GBI-EM Global Diversified index, which is the benchmark for local-currency developing-nation debt.
The proposed changes could lead to a decrease in the cap on individual countries from 10% to 8.5%, potentially increasing the average yield of the benchmark.
If implemented, the amendments would impact major bond sellers in emerging markets like Indonesia, Mexico, Malaysia, China, and India.
JPMorgan is also contemplating a new index for local markets in frontier economies, covering 21 markets across 20 currencies.
