Middle East Conflict: ASEAN Macro Shifts and Rupiah Defense

The narrow waterway remains a critical vulnerability for energy-importing Asian economies.
Diplomatic efforts to de-escalate the situation appear fragile. Pakistani Interior Minister Mohsin Naqvi arrived in Tehran for the second time this week to mediate an impasse between Iranian and Washington officials. However, US Vice President JD Vance maintains that while negotiations are making
