Fears of supply disruption drive oil prices up as geopolitical tensions escalate.
Stock markets in Asia experienced declines on Tuesday, while oil prices retreated after a significant surge the previous day, remaining above $100 per barrel.
This situation was largely attributed to ongoing hostilities between the US and Iran, which have intensified over control of the Strait of Hormuz, a critical energy trade chokepoint.
The heightened tensions cast doubt on the fragile truce previously in place.
Investors were also keeping a close eye on the Japanese yen due to its unexpected strength the previous session, sparking speculation that Tokyo may intervene to stabilize the currency.

Oil markets reacted negatively to these developments, with Brent crude futures falling 1.3 percent to $112.93 per barrel and US crude prices decreasing by 2.3 percent to $104 per barrel.
This downturn was a consequence of heightened concerns regarding supply disruptions caused by geopolitical tensions.

The Federal Reserve's monetary policy outlook may be influenced by various economic data releases scheduled for this week, including April's nonfarm payrolls report.
Market expectations suggest that the Fed will maintain its current policy interest rate for the remainder of the year due to ongoing inflationary pressures stemming from global energy shocks.
