British households are bracing for a renewed cost of living challenge as oil prices have surged past $100 a barrel for the first time since July. Brent crude reached a high of $101.58, driven by concerns over global supply amid escalating hostilities in the Middle East.
This price increase is expected to translate into higher costs for motorists at the pump and contribute to rising food and energy bills. The prospect of elevated inflation could compel the Bank of England to consider interest rate hikes in the coming months, potentially increasing mortgage expenses for homeowners.
Government borrowing costs have also seen an uptick. The yield on ten-year gilts, a benchmark for UK government borrowing expenses, is approaching a 19-year high. This financial pressure comes as the government faces demands to address cost of living issues while simultaneously managing market anxieties regarding fiscal policy.
Andrew Goodwin, chief UK economist at Oxford Economics, advised a cautious fiscal approach, citing the UK's "poor fiscal position" and "relatively weak" credibility of current borrowing reduction plans. Inflation is currently running significantly above the 2% target at 2.9%, with projections suggesting it could reach 4% next year. Thomas Pugh, chief economist at RSM UK, noted that this would mean higher input costs for businesses and potentially negative private sector pay growth for households, intensifying the cost of living pressures.
The recent spike in oil prices is directly linked to US actions against Iranian tankers and attacks on Saudi Arabia by Iran-backed Houthis in Yemen. Bank of England Governor Andrew Bailey had previously warned that the conflict and extreme weather events could contribute to a new wave of inflation. He also highlighted that UK mortgage costs have risen sharply, even without official rate increases, due to the pass-through effect of higher bond yields on borrowing costs for consumers and businesses.
While oil prices remain below the highs seen in April 2026, the conflict has disrupted critical shipping routes like the Strait of Hormuz, which once handled a substantial portion of global oil supplies. Experts warn that the ripple effects of higher wholesale prices will likely impact consumer energy bills this winter. The energy price cap is set to rise by 4% in October, with analysts predicting a further increase in early 2027, potentially by another 13%, according to Oxford Economics. The average price of petrol has already risen by 5p per litre in the past week, reaching 167.17p, with diesel increasing to 188.63p, levels not seen in four years.
