Bank of England Raises Rates to 4% for the First Time in More Than Three Years as War-Driven Energy Costs Push Inflation Towards 5%

The Bank of England raised interest rates for the first time in more than three years on Thursday, November 5, reversing course after a long series of cuts as surging energy prices linked to the conflict involving Iran threaten to push British inflation sharply higher.

The central bank's Monetary Policy Committee voted 8-1 to raise the Bank Rate by 0.25 percentage points to 4% from 3.75%, according to MoneyWeek. Eight members supported the quarter-point increase, while one member voted for a larger half-point rise. The decision had been widely expected by economists.

The Bank forecast that consumer price inflation will climb to 5% by mid-2027, mainly because of higher energy prices, according to MoneyWeek. Inflation rose to 3.5% in the 12 months to September 2026, up from 3.1% in August, well above the Bank's 2% target.

Bailey signals caution

Governor Andrew Bailey sought to reassure households and businesses that the increase did not mark the start of an aggressive tightening campaign. "Today's increase shouldn't be seen as the first in an inevitable long sequence of hikes," he said, according to MoneyWeek.

However, Bailey also warned that further increases could follow if the conflict continues to drive up energy costs. He said that, unless the war is resolved, the increase does not "seem likely to be the last," according to the BBC, as reported by Yahoo Finance.

A reversal of policy

The rise marks a significant turn for the Bank of England, which had been cutting interest rates since 2024 as inflation fell from the peaks reached after Russia's invasion of Ukraine in 2022. The bank had lowered rates from a high of 5.25% as inflation returned towards its target.

But the conflict involving Iran has disrupted oil and gas supplies from the Middle East, driving up energy prices worldwide. For the United Kingdom, which imports much of its energy, higher prices feed quickly into household bills, transport costs and business expenses, pushing up inflation across the economy.

Economists divided on what comes next

Economists offered differing views on the outlook. "Unless energy prices start to retreat, further rate hikes will move from a risk to a real prospect," said Suren Thiru, chief economist at the Institute of Chartered Accountants in England and Wales, according to MoneyWeek.

Sanjay Raja, chief UK economist at Deutsche Bank, said "we don't think this is the start of a long hiking cycle." Oxford Economics forecast a further quarter-point rise to 4.25% in February 2027, according to MoneyWeek.

What it means for households

The increase will raise costs for borrowers with variable-rate mortgages. Moneyfacts estimates that a quarter-point rise adds about £37 a month to repayments on a £250,000 tracker mortgage over 25 years, according to MoneyWeek. Borrowers on tracker and standard variable rates will feel the change fastest.

Homeowners on fixed-rate deals will be affected only when their current deals end. Lenders had already priced in the increase, according to Nick Mendes, mortgage technical manager at broker John Charcol. "The increase had been expected for weeks and was already reflected in fixed mortgage pricing," he said. The average new mortgage rate is 5.89%, the highest since November 2023, according to MoneyWeek.

Savers, by contrast, could benefit from higher returns on their deposits.

Political reaction

Chancellor John Healey said the government was acting to give "breathing space" to families and businesses, according to the BBC. The opposition Conservatives said "it's time Labour cut taxes, welfare spending and costly regulations."

The growth trade-off

Higher interest rates risk slowing the British economy, which has grown modestly. GDP grew 0.5% in the April-to-June quarter, after 0.6% growth in the first quarter, according to MoneyWeek. Raising rates to fight inflation caused by an external energy shock is a difficult balance, since higher rates cannot increase energy supply but can dampen demand and prevent inflation from becoming entrenched in wages and prices.

Global central banks tighten

The Bank of England is not alone. Central banks around the world are confronting the inflationary effects of higher energy prices. In the United States, traders see roughly a 70% chance that the Federal Reserve will raise interest rates in December, according to StockTitan. Other central banks have also raised rates or signalled a more cautious approach to easing.

The prospect of higher interest rates has added to pressure on stock markets. On the same day as the Bank of England's decision, the S&P 500 fell 4.4% and the Nasdaq entered a correction, driven primarily by a sell-off in AI and chip stocks.

Implications for India

The UK is an important economic partner for India, with the two countries having signed a free trade agreement. Higher UK interest rates and slower growth could affect demand for Indian exports and services, while also influencing currency movements. Indian students in the UK and members of the large Indian diaspora with mortgages there will feel the direct effects of higher borrowing costs.

Higher global interest rates can also affect capital flows to emerging markets such as India, although Indian markets have recently attracted strong foreign investment.

Markets react

Financial markets had largely anticipated the decision. Higher interest rates generally support a currency by making deposits more attractive to investors, but the outlook for further increases will depend on energy prices and economic data. Government bond yields, which influence borrowing costs across the economy, have risen this year as investors priced in higher inflation and interest rates.

For businesses, higher borrowing costs add to the pressures of high energy prices, which have squeezed profit margins, particularly in energy-intensive industries.

The energy shock

The surge in energy prices this year has been driven by disruption to supplies from the Middle East linked to the conflict involving Iran. Oil prices fell sharply on November 4 on hopes that the US election result could hasten an end to the conflict, but remained elevated, with Brent crude near $100 a barrel on November 6. Natural gas prices, which strongly influence British electricity bills, have also risen.

What comes next

The Bank of England will assess incoming data on inflation, wages and growth, as well as developments in energy markets, before its next decision. The path of the conflict involving Iran and its impact on oil and gas prices will be the key factor. For now, the Bank has signalled that it is prepared to act to keep inflation under control, while trying to avoid an unnecessarily sharp slowdown in the economy.
