Global markets are entering a key positioning window following the September FOMC meeting, with focus shifting to the Fed’s rate path and updated dot plot. August inflation remained firm amid higher energy prices, and markets are watching whether this signals the start of a renewed tightening cycle or remains a one-off move. Higher-for-longer rates could keep pressure on global liquidity, the USD, and risk assets broadly.

The nearer-term event for Indonesian equities is the 18 September index rebalancing, although its impact is expected to remain concentrated in a handful of names rather than the broader market:

• GDX / GDXJ (VanEck Gold Miners, tracking MarketVector indices) — effective at Friday’s close, 18 September. Final review results were announced on 11 September, 
• FTSE / FTSE Shariah — changes from the quarterly GEIS review will be announced after Friday’s close and become effective from Monday’s open, 21 September.

For the affected gold names, the flows could still be meaningful, with weight adjustments potentially translating into passive inflows in the tens of millions of dollars for names such as AMMN and BRMS, equivalent to several days of normal trading volume. For the broader market, however, we see this as a narrow, technical event rather than a broad directional driver. The impact should therefore be relatively short-lived and concentrated around the Friday and Monday closes, with limited read-through to the overall market direction.

We expect investors to remain in wait-and-see mode, with positioning likely to stay cautious as markets digest the Fed outcome and approach the upcoming index changes.
