Oil prices have surged past $90 a barrel as tensions between the U.S. and Iran intensify, with fears of supply disruptions in the Middle East driving markets. The ongoing hostilities have led to significant fluctuations in oil markets, with Brent crude experiencing a nearly 16% increase in a week. Analysts warn that renewed conflict and potential closures of key shipping lanes such as the Strait of Hormuz could jeopardize global energy security. While Gulf stock markets are retreating amid these escalating tensions, fuel prices are rising, prompting concerns over economic impacts and investor sentiment. The implications of this renewed crisis include potential interest rate hikes and broader effects on global supply chains.
