Indonesia’s financial markets are expected to remain under pressure from several negative external factors, including the latest announcement from MSCI, rising US inflation and war.
Rising US producer prices could bring a new “storm” to global financial markets, including Indonesia.
Market participants will also focus on a discussion involving the Federal Reserve chair at the IMF-World Bank meetings. Domestically, cabinet reshuffle rumours are expected to influence the market today.
The following are some of the market factors to watch today:
- MSCI threatens to downgrade Indonesia’s equity-market status: why
Morgan Stanley Capital International (MSCI) has opened a consultation on changing Indonesia’s equity-market classification from Emerging Market to Standalone Market. A final decision is expected to be announced by 30 June 2027 at the latest.
MSCI has highlighted investors’ concerns about ownership transparency, alleged coordinated trading practices and the effectiveness of enforcement. Although regulators have announced several reforms, MSCI said it had not seen sufficient and consistent progress.
In line with the proposal, MSCI is maintaining a freeze on several changes to Indonesian equity indices. It will not increase the Foreign Inclusion Factor (FIF) or Number of Shares (NOS), add stocks to the MSCI Indonesia Investable Market Index (IMI), or move stocks into larger-capitalisation index segments.
Market participants may submit feedback until 30 April 2027. MSCI said the proposed reclassification could be reconsidered if the consultation produces evidence of material improvements in the governance and functioning of Indonesia’s equity market.
- War update: Houthis attack Yemen’s presidential palace, killing five
Yemen’s Houthi group launched missile and drone attacks on the Al-Maashiq Presidential Palace compound in Aden on Thursday (15 October 2026). The attacks killed five people and injured 16. Yemen’s government said the Prime Minister and several cabinet members were safe. The Houthis, meanwhile, claimed the attack targeted the headquarters of Saudi Arabia’s military operations in Aden.
- US inflation heats up as producer prices post biggest rise in four and a half years
Inflation in the United States is accelerating. Producer prices rose 1.3% month on month in September 2026, their biggest increase since March 2022 and well above market expectations of 0.5%. US Labor Department data released on Thursday (15 October 2026) showed the Producer Price Index (PPI) rose 6.3% year on year, its highest level since December 2022.
Price pressures also spread to the services sector. Producer prices for services rose 0.8%, while road freight costs increased 3.8% and air fares surged 5%.
- US jobless claims rise, but labour market remains resilient
The US also reported a slight increase in the number of people filing initial unemployment-benefit claims in the week ended 10 October 2026. However, the figure was below market expectations, reflecting continued strength in the US labour market.
The Labor Department said initial claims rose by 1,000 to 199,000, slightly below the market forecast of 200,000. Continuing claims fell by 4,000 to 1.71 million. This remained relatively close to the lowest level in more than three years, recorded two weeks earlier.
The figures indicate that the US labour market remains resilient, in line with the Federal Reserve’s assessment that employment conditions are around the level consistent with full employment.
- Federal Reserve chair and IMF managing director to hold discussion
The IMF-World Bank meetings in Bangkok, Thailand, include an important event on Friday (16 October 2026): a fireside chat between International Monetary Fund (IMF) Managing Director Kristalina Georgieva and Federal Reserve Chair Kevin Warsh.
The discussion, scheduled for 10.30am WIB, could offer clues about the global economic outlook, inflationary pressures, the direction of US interest rates and global debt risks.
Warsh’s remarks are attracting market attention because they could influence expectations for Federal Reserve monetary policy, the US dollar, US Treasury yields and gold prices. For Indonesia, signals of tighter Fed policy could put pressure on the rupiah and prompt capital outflows from emerging markets, while a more dovish signal could support risk assets.
