Part of MSCI placed the Indonesian market on watchlist due to transparency concerns, prompting potential downgrade review.

How could the Indonesia Stock Exchange overhaul affect Bank Indonesia's market stability role?

Possible What happens if… A possibility worth considering, not a forecast.

The overhaul of the Indonesia Stock Exchange may require Bank Indonesia to adjust its market oversight. The Indonesia Stock Exchange (IDX) began a structural overhaul by excluding stocks with High Shareholding Concentration (HSC) from its benchmark index calculation. This change, prompted by MSCI warnings regarding market quality, alters the fundamental structure of the domestic financial market. Because Bank Indonesia strategically influences the IDX through monetary policy and coordination, this major shift in market governance necessitates that the central bank adjust its oversight and coordination efforts to maintain overall market stability.

Tap any step to see the evidence behind it.

The facts so far

As reported. Each one links to where it comes from.

  • The IDX officially began excluding stocks with high shareholding concentration (HSC) from its benchmark index calculation.thejakartapost.com
  • The bourse previously unveiled that it had 80 stocks listed under the HSC category, which account for about 18 percent of the index’s total weighting.thejakartapost.com
  • The overhaul is prompted by MSCI warnings.thejakartapost.com

Why it matters

The stability of the Indonesian financial market is critical for Bank Indonesia, as the central bank is responsible for maintaining monetary policy and overall economic health. Structural changes like the exclusion of HSC stocks affect the weighting and composition of the primary domestic index, which is a key indicator of market health.

This overhaul occurs against a backdrop of international scrutiny, specifically from MSCI, which placed the Indonesian market on a watchlist due to transparency concerns. This puts pressure on the IDX and, by extension, the central bank to demonstrate effective governance and stability to international financial providers.

What we don't know yet

  • How will the redistribution of weights from the removed HSC stocks affect overall market volatility?
  • What specific coordination mechanisms will be established between the IDX and Bank Indonesia following the overhaul?
