Global and Indonesian financial markets will be watching several important events and economic data releases from China and the United States this week.
The International Monetary Fund (IMF) meeting in Bangkok, Thailand, is one of the main events. A number of senior officials are due to attend and speak, including Federal Reserve Chair Kevin Warsh.
Wednesday is expected to be particularly significant, with US and Chinese inflation figures and China’s trade balance due.
Domestic catalysts are relatively limited, although political tensions could rise as the second anniversary of the Prabowo-Gibran administration approaches.
Key market events today and over the coming week include:
- Trump considers helping Saudi Arabia strike the Houthis as Iran war widens
US President Donald Trump is considering helping Saudi Arabia attack the Houthi movement in Yemen following a deadly attack at Riyadh Airport. Such a move could draw the US into a new front in the Iran war.
“We might do it. We’ll consider it,” Trump told reporters at the White House on Saturday (10 October 2026), according to Reuters.
- IMF and World Bank meetings (12–18 October)
Global finance officials will gather in Bangkok, Thailand, for the annual IMF and World Bank meetings. The event is taking place amid geopolitical turmoil, rising energy costs, higher interest rates and mounting public debt.
Under the theme “Thailand’s New Horizons: Empowering People, Building Resilience”, discussions will cover the global economic outlook, financial stability, poverty reduction, job creation and the role of private investment in development.
- China inflation (Wednesday, 14 October)
China is due to release its September 2026 consumer price index (CPI) and producer price index (PPI).
In August, Chinese consumer inflation reached 0.8% year on year, up from 0.5% in July. Producer inflation rose to 3.8% from 3.5%.
The latest figures will offer an indication of the strength of domestic demand and cost pressures in the world’s second-largest economy. The developments matter to Indonesia because China is a major trading partner and an important market for Indonesian commodity exports.
- China trade balance (Wednesday, 14 October)
China will also publish its September 2026 trade data. In August, the country recorded a trade surplus of US$119.09 billion.
Exports surged 25% year on year to US$401.44 billion, while imports grew 28.2% to US$282.36 billion.
Investors will be watching to see whether the trade surge continues. Growth in Chinese imports could benefit Indonesian exports, particularly if demand for commodities strengthens again.
- US inflation (Wednesday, 14 October)
The September US inflation figures are among the week’s most anticipated releases. They could provide clues about the Federal Reserve’s interest-rate policy.
In August, annual US inflation held at 3.4%, while monthly inflation rose 0.4%, driven primarily by petrol prices.
If price pressures rise again, the Fed may have less room to ease monetary policy. The effects could be felt in the US dollar, bond yields, the rupiah and emerging-market share prices.
- Federal Reserve officials’ speeches (14–16 October)
Comments from Fed officials will also be closely watched. Fed Vice-Chair for Supervision Michelle W. Bowman is scheduled to attend an event in Bangkok on 14 October.
The following day, Fed Chair Kevin Warsh is due to take part in a discussion with IMF Managing Director Kristalina Georgieva.
