Indonesia Stock Exchange says it has taken various concrete steps to enhance its transparency and integrity of Indonesia's capital markets in response to MSCI announcement

The sequence here is a familiar one: an index provider flags structural concerns about a market, the local exchange responds publicly with remedial measures, and the standoff plays out over subsequent index reviews. Index provider interventions of this kind have historically centred on issues such as free float definition, concentrated ownership, and investability, and exchanges placed in this position have tended to announce transparency and free float reforms precisely because retaining index standing, and the passive flows tied to it, depends on visible compliance. The distinction worth drawing is between cosmetic measures and changes that alter the actual float and ownership data providers assess: the former buys time, the latter moves the methodology outcome. The follow-ons are the next index review cycle, any formal watchlist or reclassification language from the provider, and whether concrete rule changes on disclosure or float thresholds follow. Foreign flow behaviour into Indonesian equities has in past episodes of this kind tracked the provider's tone rather than the exchange's assurances.
