Bank of England hikes interest rates for first time since 2023

The Bank of England changed its main interest rate, called the base rate, from 3.75% to 4%. This makes borrowing more expensive across the economy. The Monetary Policy Committee voted unanimously for an increase, although Catherine Mann wanted a larger 0.5 percentage-point rise. The decision matters because it signals that policymakers see enough inflation pressure to act now.

The increase is the first since August 2023 because rates had not been raised for more than three years. The Bank had previously held the rate at 3.75%, but energy and fuel prices have jumped as the conflict involving the US, Israel and Iran intensified. Governor Andrew Bailey said some price increases are already in the pipeline, even if the conflict ends quickly.

The Bank is not promising a long series of increases. Bailey said another rise is unlikely to be the last unless the conflict is resolved. The immediate goal is to limit demand and stop higher energy costs from creating broader, persistent inflation.

The Bank of England’s base rate is the central interest rate used to guide monetary policy. It is not every bank’s customer rate, but it strongly influences the rates banks charge for borrowing and the returns they offer on savings. The Bank changes it to affect spending, saving and investment across the economy. That makes it an important tool for controlling inflation.

When the base rate rises from 3.75% to 4%, banks face a higher benchmark for money. They may respond by increasing rates on mortgages, business loans, credit and other borrowing. Some households and companies therefore pay more to service debt. Other people may save more because saving becomes relatively more attractive. These changes can reduce the money available for spending.

The effect is gradual rather than immediate. Higher borrowing costs can weaken demand, encouraging firms to limit price increases. The Bank’s decision reflects rising energy-driven inflation, but its broader purpose is to prevent that shock from becoming entrenched throughout the economy.

The Monetary Policy Committee raised the Bank rate by 0.25 percentage points, from 3.75% to 4%. One member, Catherine Mann, preferred a larger 0.5 percentage-point increase. The decision shows a measured response rather than the bigger move some policymakers might have supported. It also confirms that the Bank sees inflation pressure as serious enough to require higher borrowing costs.

The Bank expects inflation to reach around 5% in the second quarter of 2027. That is one percentage point above the new base rate. The comparison is not a direct measure of whether policy is tight enough, because interest rates and inflation measure different things. Still, it shows the scale of the expected price pressure facing households and businesses.

The 4% rate is twice the Bank’s 2% inflation target. The Bank expects inflation to fall steadily after its peak and return to that target in the third quarter of 2028. Higher rates are intended to help that decline by weakening demand and limiting further price increases.

Energy and fuel prices are the immediate cause of much of the inflation pressure described in the article. Raising interest rates cannot directly lower those prices or end the conflict affecting energy markets. It targets the second-round effects instead. The Bank wants to prevent higher energy bills from triggering broad wage, spending and price increases across the economy.

A higher base rate makes borrowing more expensive. Households may delay purchases or cut discretionary spending, while businesses may postpone investment or face higher finance costs. With weaker demand, firms may find it harder to pass every increased cost on to customers. The mechanism is indirect, but it can limit how far the original shock spreads.

The Bank warned that companies had been absorbing energy costs through profit margins or hedging. Those buffers may disappear if the energy shock continues. The rate rise therefore aims to contain future inflation while the Bank expects prices to peak around 5%, then eventually return to its 2% target.

Energy is used throughout production and distribution. When fuel and power become more expensive, manufacturers, transport companies and other businesses face higher operating costs. The pressure does not stop with energy suppliers. It can move through several stages as each business pays more to make, move or provide something.

The article gives a clear mechanism. Some companies have so far absorbed higher energy costs through smaller profit margins or protected themselves with hedges. Those buffers are temporary. If energy prices stay high, firms may pass the extra costs to wholesalers, retailers and customers. This can raise prices for food, drink, goods and services.

Households may face especially strong pressure from energy bills and food. Ofgem was expected to raise its household price cap by almost 25%, to an average annual bill of £2,150 in January. Food inflation was forecast to reach 4.8% next year, reflecting manufacturers’ energy costs and possible supply-chain pressure linked to El Nino.

The rate increase most directly affects people and businesses that borrow money. Households with mortgages, loans or other credit may face higher payments. Businesses that rely on finance also pay more or reconsider borrowing. The effect can be especially difficult because the decision comes alongside rising energy bills and other cost-of-living pressures.

Higher borrowing costs change behaviour. Families may delay major purchases, reduce optional spending or save more. Companies may postpone investment, hiring or expansion because projects become more expensive to finance. Weaker demand can make it harder for firms to raise prices, while higher finance costs can squeeze their profits. These are the main ways monetary policy works through the economy.

The article also notes that stronger business investment, partly linked to AI, helped recent growth. The economy was forecast to grow 1.6% this year, but growth was expected to slow to 1.3% afterward as higher inflation weighs on activity. The rate rise therefore brings tighter conditions as households and firms face a squeeze.

Monetary policy works through a chain of effects. The Bank raises its base rate, banks increase borrowing costs, and households and businesses have less money or willingness to spend. Some may save instead. This lowers demand for goods, services and investment. The process matters because inflation can persist when businesses believe customers will continue accepting higher prices.

For example, a family may postpone a large purchase after its loan becomes more expensive. A company may delay an expansion because financing costs rise. When enough households and firms make similar decisions, sales growth slows. Businesses then have less scope to pass every cost increase to customers. This does not remove an energy shock, but it can stop the shock spreading further.

The effect takes time, which is why the Bank is looking ahead rather than reacting only to current prices. It expects inflation to peak around 5% in the second quarter of 2027, then fall steadily to its 2% target in the third quarter of 2028. Higher rates are intended to support that path.
