Financial market movements this week will be overshadowed by tensions in the Middle East, interest rate decisions from several central banks, and the release of domestic and international economic data.
Markets are closely monitoring the Houthi and Saudi Arabia conflict, the Bank of Japan’s (BOJ) interest rate hike, and China’s decision regarding the Loan Prime Rate. Domestically, primary attention is focused on the Bank Indonesia Board of Governors Meeting (RDG) and developments in money supply.
Meanwhile, the United States is scheduled to release durable goods orders data at the end of the week.
Market movements are also being influenced by US monetary policy and high energy commodity prices. The Federal Reserve (The Fed) raised interest rates last week for the first time in three years, as the US continues to face persistent inflation and high bond yields.
Oil prices currently remain around US$100 per barrel, while 10-year US Treasury yields are holding near the 5% level. This situation is a point of concern for investors as it could increase inflationary pressure and influence the direction of global monetary policy.
Amidst these conditions, the meeting between Trump and Xi is one of the key agendas attracting market attention this week. The meeting is expected to discuss several economic issues, including trade tariffs, critical minerals, artificial intelligence (AI), and various other economic matters.
Ahead of this meeting, US Treasury Secretary Scott Bessent also met with Chinese Vice Premier He Lifeng. The meeting between Bessent and He was conducted as part of preliminary discussions prior to the visit and meeting between Trump and Xi.
