Expectations around interest rates set by the Bank of England have changed quickly as global events begin to affect financial markets. Investors are reassessing the outlook for borrowing costs after a sharp rise in oil prices linked to conflict involving the United States, Israel and Iran. The surge in energy prices has raised concerns that inflation could increase again, potentially forcing policymakers to reconsider their plans for interest rates.
Only a few weeks ago, markets were largely expecting interest rates to move in the opposite direction. Many investors believed the central bank would soon begin lowering borrowing costs as inflation gradually moved closer to its target level. However, the recent jump in energy prices has complicated that outlook.
Financial markets are now indicating a growing chance that the Bank of England may raise interest rates before the end of the year. Current market pricing suggests there is roughly a 70% probability that the central bank could increase its benchmark rate by a quarter of a percentage point.
If such a move takes place, it may occur toward the end of the year, potentially in December. This would push borrowing costs above the current base rate of 3.75%, reversing earlier expectations that the next move would likely be a cut.
The change in outlook has happened very quickly. Just two weeks earlier, many traders expected the central bank to introduce rate cuts during 2026. Some even anticipated the first reduction could take place in the near term.
However, developments in global energy markets have led investors to rethink those forecasts. Rising oil prices have raised the possibility that inflation could strengthen again, which would make it harder for policymakers to lower borrowing costs.
One of the main drivers behind the shift in expectations has been the sharp movement in global oil markets. The price of Brent Crude, widely used as an international benchmark, climbed sharply and briefly approached $120 per barrel after surging by almost 30%.
Another important oil benchmark, West Texas Intermediate, also experienced one of its strongest weekly gains on record. The rapid rise in prices has reflected growing concerns about potential disruptions to global oil supplies.
A key area of concern is the Strait of Hormuz, one of the world’s most important shipping routes for oil. A large share of global energy exports passes through this narrow waterway in the Gulf region.
Any prolonged disruption to shipping in this area could reduce supply in global energy markets and place further upward pressure on prices. Even the possibility of disruption has been enough to trigger sharp movements in oil markets.
Although prices have eased slightly since their peak, they remain volatile as traders continue to monitor developments in the Middle East. Ongoing tensions could keep markets unsettled for some time.
Some analysts have questioned whether raising interest rates would be the correct response to the current situation. Chris Beauchamp, chief market analyst at IG Group, suggested that the surge in oil prices represents a supply shock rather than an increase in demand.
He noted that higher energy costs are likely to reduce consumer spending by increasing household bills. As a result, raising borrowing costs could place additional pressure on the wider economy.
If interest rates rise too quickly in response to supply-driven inflation, there is a risk that economic growth could slow more sharply than expected. This concern has led some economists to urge policymakers to proceed cautiously.
Economists are now adjusting their forecasts for the next steps from the Bank of England. Analysts at Oxford Economics expect policymakers to keep interest rates unchanged at their next meeting while they assess the evolving situation.
At the same time, the consultancy has revised its inflation forecasts upward for the later part of the year. Higher energy costs are likely to push up household bills and could feed through into the prices of goods and services.
Some members of the Bank’s Monetary Policy Committee had previously hoped that falling inflation would help reduce wage growth pressures across the economy. However, the renewed increase in energy costs could make that outcome less likely.
As a result, many economists now believe that any interest rate cuts could be delayed. Instead of arriving in the near term, the first reduction may not happen until at least April next year.
Financial markets have already started reacting to these shifting expectations. Investors who had previously bet on several rate cuts have begun scaling back those predictions.
Rising energy prices have also influenced borrowing costs across financial markets. Government bond yields have climbed, increasing the cost of financing public debt for the Treasury.
Mortgage borrowers may also feel the impact of these developments. Fixed-rate mortgage pricing is closely linked to swap rates, which have already started to rise in response to changing interest rate expectations.
While inflation has fallen significantly from its peak of 11.1% in October 2022 to around 3% earlier this year, it still remains above the central bank’s 2% target. Any renewed rise in energy prices could slow the progress that has been made in bringing inflation under control.
The nine members of the Monetary Policy Committee remain divided over the best course of action. Some policymakers are concerned that cutting rates too quickly could allow inflation to rise again.
Others believe the central bank should consider easing borrowing costs sooner in order to support economic growth and address rising unemployment.
For now, the future path of UK interest rates appears far less certain than it did only a short time ago. With global tensions continuing and energy markets unsettled, policymakers may have to remain cautious as they balance inflation risks against the need to support the economy.
