Oil price jumps above $117 after reports of 'extended' Iran blockade

Iran has severely restricted shipping through the strait — which usually carries about a fifth of the world's supply of oil and liquid natural gas — in response to US and Israeli strikes that began on 28 February.Earlier this month, Tehran warned that any vessel that approaches the strait would be targeted.The US then announced that its forces would intercept or turn back vessels travelling to or from Iran's ports.Analysis by BBC Verify shows that at least four vessels tracked from Iranian ports appear to have crossed the US blockade line.Despite the fluctuations of recent weeks, the price of oil remains much higher than the pre-conflict price of a barrel.The price of Brent crude dropped to $90 a barrel on 17 April, after a ceasefire between Israel and Lebanon was announced. The US said it would pause attacks on Iran on 8 April. It remains much higher than the pre-conflict price of a barrel.However, the oil benchmark has been rising steadily over the last 12 days, as the US continued its blockade.Lindsay James, investment strategist at Quilter, said that the impact of the war so far in the UK has been largely limited to higher petrol and diesel prices, but "every day that passes without a resumption of supply sees the risk of physical shortages and steeper price rises on a range of goods increasing".The Iranian economy is facing a deepening crisis, with rapidly rising prices, falling currency value, and prospects of the oil exports grinding to a halt.According to the Statistical Center of Iran, the annual inflation rate has risen to 53.7%. The country's currency, the rial, has fallen to a record low.Around two million Iranians have lost their jobs, directly or indirectly, as a result of the war, the Iranian government had said last week.On Wednesday, Trump urged Iran to 'get smart soon' and sign a deal, following days of deadlock in efforts to end the conflict.In a post on Truth Social, Trump said the country 'couldn't get its act together.'The Wall Street Journal cited US officials as saying the president had instructed aides to prepare for an extended blockade of Iran's ports in a bid to force Tehran's hand.Officials said Trump had opted to continue squeezing Iran's economy and oil exports with the blockade as his other options - resuming bombing or walking away from the conflict - carried more risk, according to the report.Iranian officials said on Tuesday the country could withstand the blockade as it was using alternative trade routes.The World Bank on Tuesday forecast energy prices would surge by 24% in 2026 to their highest level since Russia's full-scale invasion of Ukraine four years ago, if the most acute disruptions caused by the Iran war end in May.European stocks fell on Wednesday, as investors digested a wave of corporate earnings and awaited the US Federal Reserve's latest interest rate decision.The FTSE 100 was down 1.2% in the afternoon, while the pan-European Stoxx index was down 0.69%.France's Cac was down 0.5% and Germany's Dax fell 0.36%.In the US, the Nasdaq made marginal gains in the early hours of trading. The S&P was 0.15% down on opening.Asian stock markets mostly rose Wednesday, continuing their recovery after being particularly hard hit by the initial shock from the war.
