Indonesian stocks suffered their largest foreign outflow in over two decades, with PT FAP Agri block trades identified as the primary driver. The palm oil producer's sudden sell-off triggered a net outflow of $1.2 billion, marking the highest in 21 years. MSCI Inc.'s recent investability concerns have intensified scrutiny on ownership structures in the sector, potentially prompting foreign investors to reduce exposure. PT FAP Agri is a major player in Indonesia's palm oil industry, and its block trade activity suggests strategic repositioning amid regulatory uncertainty. This development signals shifting investor sentiment in Southeast Asia's largest economy, where foreign holdings in local equities remain sensitive to governance issues.

The outflow reflects broader caution as global funds reassess emerging market risks following MSCI's warnings about corporate governance standards. PT FAP Agri's role as a key commodity exporter amplifies the market impact, as its liquidity events can disproportionately affect sectoral valuations.
