The Indonesian financial markets this week will only operate for four days, Monday to Thursday, due to Labour Day holiday on 1 May or this coming Friday.
The main focus of the market this week is on the latest developments in US-Iran negotiations, the Federal Reserve’s interest rate decision, the release of US PCE inflation data, US and China manufacturing data, and the Bank of Japan’s (BOJ) interest rate decision.
Markets expect the Fed to hold its benchmark interest rate in the 3.50%-3.75% range. This expectation arises because US inflation remains above target, while the surge in energy prices due to Middle East conflicts makes it difficult for the US central bank to move too quickly to ease policy.
This Fed decision will be very important for global markets. If the Fed signals it will hold rates longer, the US dollar could remain strong. This condition could again pressure Asian currencies, including the rupiah.
Conversely, if the Fed’s statement begins to sound more dovish by considering the risk of economic slowdown, markets could interpret it as an opportunity for rate cuts in the following semester. This scenario could provide room for strengthening bonds and risk assets, including stocks in emerging markets.
