Financial market movements today and over the coming week are expected to remain overshadowed by heightened global uncertainty due to the conflict in the Middle East. After world oil prices soared and market volatility increased in recent weeks, investors are now awaiting a number of key economic data points that could provide clues on the direction of global economic growth, interest rate prospects, and exchange rate stability.
The market’s main focus will be on the interest rate meetings of Bank Indonesia and the US Federal Reserve, US consumption data, and a series of economic indicators from China, which serves as a barometer for global commodity demand. For Indonesia, the combination of this data will influence the movement of the rupiah, the IHSG, the bond market, and the prospects for commodity sectors such as coal, nickel, and crude palm oil (CPO).
