In a landscape shaped by escalating geopolitical tensions, the Bank of England is expected to keep its base interest rate steady at 3.75% for the remainder of 2026. Financial markets now predict a rise to 4% by next summer, a shift in sentiment catalysed by the ongoing conflict involving Iran, which has significantly impacted global oil prices and economic forecasts.
Interest Rates Hold Steady
Following the onset of the US-Israel conflict with Iran, financial analysts have revised their outlook on UK interest rates. What once seemed a near certainty—an interest rate cut during the Bank’s upcoming meeting on 19 March—has now dramatically shifted, with investors assigning a 99% likelihood that the rate will remain unchanged through the year.
Before the conflict escalated, forecasts indicated an 80% chance of a rate cut. However, the current situation has painted a different picture, with market data suggesting a cautious approach from policymakers who are likely to await further developments before making any decisions.
Bond Yields Surge
Recent events have driven UK two-year bond yields to a notable 4.129%, marking the highest level since April 2025 and up from 3.52% prior to the conflict. This surge in yields, which serves as a barometer for future interest rate expectations, indicates a significant financial response to the upheaval in the Middle East.

Chris Beauchamp, chief market analyst at IG, commented that the ramifications of the Iran conflict, which has effectively threatened to disrupt oil supplies through the Strait of Hormuz, are now being felt across European stock markets. The FTSE 100, for instance, initially dropped by 200 points, reflecting investor trepidation.
Impact on Mortgage Rates
As the Bank of England signals a hold on interest rates, UK mortgage lenders have responded by increasing home loan rates, further straining household finances. Recent data from Moneyfacts reveals that the average two-year fixed mortgage rate has climbed to 4.87%, while five-year fixed rates have also seen a rise to 4.98%.
These increases suggest that homeowners may face prolonged periods of higher mortgage costs, contributing to the already challenging living standards for many.
Global Market Reactions
Wednesday’s market activity demonstrated the wide-reaching effects of geopolitical events on financial stability. Brent crude oil prices have soared above $100 a barrel, prompting fears of rampant inflation in the UK and across Europe, where energy imports comprise a significant portion of economic activity.

As investors react to rising oil prices, the implications for inflationary pressures are becoming clearer. Anna Titareva, an economist at UBS Investment Bank, noted that the majority of the Bank’s monetary policy committee is likely to be concerned about these rising energy costs. Only a minority are expected to advocate for a rate cut, as the situation continues to evolve.
Beauchamp further highlighted that the current economic climate is driven more by supply chain issues rather than demand surges, cautioning against a rapid response from central banks that could inadvertently deepen a recession.
Why it Matters
The Bank of England’s decision to maintain interest rates amid escalating geopolitical tensions underscores the precarious balance policymakers must navigate between stabilising inflation and supporting economic growth. As the conflict in Iran continues to unfold, the resultant volatility in oil prices could have profound implications for UK households and the broader economy, making the next few months critical for financial planning and forecasting. As such, both consumers and investors alike must brace for a period of uncertainty, with the potential for increased costs and economic adjustments ahead.
