Global markets turned cautious on Wednesday as investors await the US Federal Reserve's interest rate decision, while geopolitical developments in the Middle East added to uncertainty. The Fed is expected to keep its policy rate unchanged, according to market expectations.

A US official stated that four ballistic missiles launched by Iran at a US base in Jordan were intercepted. Meanwhile, US Central Command (CENTCOM) announced that US and Saudi Arabian forces conducted airstrikes on targets linked to Iran-backed groups in eastern Iraq. Iran's Islamic Revolutionary Guard Corps (IRGC) reported targeting three oil tankers attempting to pass through the Strait of Hormuz that allegedly ignored warnings. Analysts said the resumption of conflict shows parties are far from a solution.

There were also reports that the US banned new Chinese-made humanoid robots to protect AI development, adding to trade tensions.

Federal Reserve Decision in Focus

The US Federal Reserve (Fed) is expected to keep its policy rate unchanged at its decision today. Low June consumer and producer inflation data give the Fed time to assess energy sector disruptions and inflation over the summer. Fed Chair Kevin Warsh's press conference will be watched for forward guidance and information on Fed task forces and monetary policy stance. Money markets price in rates to be kept unchanged in July, but a rate hike possibility remains on the table.

If the policy rate is kept unchanged, hawkish comments about a possible rate hike in September or other months would be interpreted as maintaining a hawkish stance. If a tight monetary policy message is given for September, it is expected to support the dollar and bond yields. If no tight monetary policy message is given, risky assets could benefit positively.

The US 10-year Treasury yield traded flat at 4.61%. The US Dollar Index fell 0.2% to 101.3.
