US officials cited by Iran International says Iran's response to the US proposal has blocked the path to a diplomatic solution with Tehran; "The next steps by Trump after receiving Iran's negative response are still unclear"

The reported blockage of diplomatic solutions between the US and Iran raises concerns about potential further escalation in the region, which could weigh on markets. This uncertainty may impact risk sentiment across assets like equities and commodities, particularly oil and gold, as geopolitical tensions often drive safe-haven assets higher. Investors will likely monitor this situation closely for any further developments or responses from the US administration.
