- Oil prices have overtaken AI as the primary market driver as investors weigh mediation hopes against escalating US-Iran attacks in the five-month-old conflict, with Brent crude easing from a one-month high on Tuesday
- Yemen's Iran-aligned Houthis announced a naval blockade on Saudi Arabia, a move the source says could trigger further oil supply shockwaves beyond existing Strait of Hormuz tensions
- Tehran received a proposal from mediators for a 10-day ceasefire, which traders latched onto despite having seen similar false dawns since the war erupted
- South Korea's KOSPI jumped nearly 5% on the day as lower oil prices boosted sentiment for beaten-down chip stocks, though the index remains down 19% in July even after a 62% year-to-date gain
- European futures slipped 0.3%, signaling fragile sentiment as the Middle East escalation has revived inflationary worries, lifted yields, and kept the US dollar on a stronger footing
- UK Prime Minister Andy Burnham, the country's seventh leader in a decade, pledged to stick to the previous government's fiscal rules — a commitment that triggered a sharp drop in sterling and British government bonds on Monday amid concerns over Iran war fallout
Why it matters: The flip from AI to oil as the market's dominant narrative means geopolitical supply risk is now overriding tech valuations, with the KOSPI's 5% single-day rebound showing how fast sentiment rotates when Brent retreats. For new UK PM Burnham, committing to fiscal rules while war-driven inflation pressures build has already cost sterling and gilts, and investors will read Tuesday's UK wage data as the first test of whether that discipline holds.
