Oil prices experienced a decline of more than a dollar per barrel on Friday due to a strengthening dollar and profit-taking by traders following a strong rally. Brent crude futures settled at $79.87 per barrel, down 1.8%, while U.S. West Texas Intermediate crude futures fell 1.9% to $75.42 a barrel. The strengthening of the U.S. dollar index contributed to the decline as it reduces oil demand and increases the cost of crude for investors holding other currencies. However, analysts anticipate that the rally may resume next week due to factors such as easing inflation, plans to refill the U.S. strategic reserve, supply cuts, and disruptions in oil-producing regions. Supply disruptions in Libya and Nigeria, along with reduced Russian oil exports, have heightened concerns about tightening markets.
