Global energy prices and borrowing costs have surged significantly as escalating tensions in the Middle East fuel widespread fears of accelerating inflation.
Oil prices have reached $105 a barrel, with Brent crude climbing steadily after crossing the $100 threshold on Wednesday. The upward pressure on energy markets follows the effective closure of the Strait of Hormuz, a critical maritime corridor, which has blocked Gulf oil and gas supplies from reaching international markets. Additionally, concerns have intensified following reports that Iran-aligned Houthi forces seized the key Red Sea port of Mocha in Yemen, threatening further disruptions to global shipping.
The geopolitical standoff shows no immediate signs of easing. Speaking at a Republican Party convention in Texas on Wednesday, President Donald Trump remarked that he does not expect the conflict between the United States and Iran in the Gulf to conclude until after the U.S. mid-term elections in November.
Meanwhile, wholesale natural gas prices are also soaring. In the United Kingdom, the cost of gas surpassed 200p per therm for the first time since the end of 2022. This spike is compounded by European gas storage levels being significantly lower than normal for this time of year, intensifying the race to replenish reserves before winter.
While UK households are temporarily shielded from immediate wholesale fluctuations by Ofgem's energy price cap, prolonged high prices will eventually lead to more expensive bills. The price cap is already scheduled to increase by 3.6% at the beginning of October, with the subsequent adjustment set for January.
The broader economic fallout is manifesting in global financial markets. Anxiety over inflation has driven government bond yields to historic highs. In the UK, yields on 10-year government bonds reached their highest level since 2007 on Thursday, while 20- and 30-year bond yields hit peaks not seen since 1998. These surging yields not only elevate borrowing costs for a government already facing pressured public finances, but they also threaten to drive up consumer borrowing rates for products like fixed-rate mortgages.
