📝 Executive Summary
Rising oil prices, fueled by Iran-linked geopolitical risks around the Strait of Hormuz, sparked a broad risk-off move across UK markets. The FTSE 100 fell as higher energy costs dented corporate margins, while gilt yields dropped on safe-haven demand. Brent crude surged past $85, its highest in three months, as traders priced in potential supply disruptions from heightened US-Iran tensions and rhetoric from the Trump administration.
