Iran War-fueled Fuel Costs Push UK Inflation to 3.5%

WHO:

CNBC - The U.K.’s Office for National Statistics (ONS) reported the inflation data.

CNBC - Scott Gardner, an investment strategist at J.P. Morgan Personal Investing, commented on inflation and the Bank of England’s policy outlook.

CNBC - Bank of England policymakers will assess inflation beyond the headline rate, including services inflation.

WHAT:

ABC News Business - U.K. inflation rose to its highest rate in almost a year as fuel prices increased amid the Iran war.

CNBC - U.K. inflation was 3.5% over the 12 months to September, above Reuters-polled economists’ forecast of 3.4%.

CNBC - Annual inflation rose from 2.9% in July to 3.1% in August and 3.5% in September.

CNBC - U.K. motor fuel prices rose 29.8% over the year to September; the motor fuel inflation rate reached its highest level since August 2022.

CNBC - The British pound was flat against the euro and U.S. dollar after the data release; U.K. government bond yields were little changed.

CNBC - Markets priced a 98% chance of a 25-basis-point Bank of England rate increase to 4% next month. Most traders also priced in another 25-basis-point increase at the bank’s final meeting of the year in December.

CNBC - Gardner said headline inflation growth had “undone the progress we saw in the spring.” He said services inflation had accelerated and could indicate “second round inflationary effects beyond energy prices.”

WHERE:

CNBC - The report concerns the United Kingdom. The article identifies Britain as a net energy importer and says oil movement through the Strait of Hormuz was affected by the conflict.

CNBC - The accompanying photograph shows a person walking near the Bank of England in London, Britain.

WHY:

ABC News Business - The Iran war drove fuel prices higher.

CNBC - Surging motor fuel costs drove the higher inflation reading. The article links energy pressures to the U.S.-Iran war and the subsequent struggle to move oil through the Strait of Hormuz.

CNBC - Gardner said the prolonged conflict was weighing on the U.K. economy and strengthening the case for a rate hike.

(UPDATED October 21, 2026 16:19 UTC)

U.K. inflation climbed to 3.5% in the year to September, its highest rate in almost a year and above economists’ forecast of 3.4%. The Office for National Statistics reported that annual inflation had risen from 2.9% in July to 3.1% in August. Higher fuel prices, driven by the Iran war and disruption to oil movements through the Strait of Hormuz, led the increase. Motor fuel prices were up 29.8% over the year, the sharpest annual rise since August 2022. Investment strategist Scott Gardner said the latest increase had undone progress made in the spring, while faster services inflation could point to further price pressures beyond energy. The pound and government bond yields were little changed after the figures. Markets saw a 98% chance of a quarter-point Bank of England rate increase to 4% next month, with most traders also expecting another increase in December.
