At the intersection of diplomacy and geography, oil markets absorbed two converging shocks on Friday: armed attacks on tankers threading through the Strait of Hormuz — the narrow passage through which a fifth of the world's oil must travel — and the quiet collapse of ceasefire talks between Washington and Tehran. Brent crude settled at $88.52 a barrel, a weekly gain of six percent, as traders priced not merely a disruption but a closing of the exit door. When the diplomatic off-ramp disappears, markets begin measuring time differently — not in days, but in the duration of uncertainty itself.
