Cast your mind back to January 2026. Most forecasters were expecting the Bank of England to cut interest rates at least twice during the year, and many borrowers were quietly hopeful that the cost of their mortgage would ease before long. Fixed-rate deals had been drifting downward. The worst of the post-pandemic inflation surge felt like it was behind us.<\/p>\n
Then, in late February and early March, the situation in the Middle East escalated sharply. Oil and gas prices spiked. The Bank of England, which had been on course to reduce rates further, held them at 3.75% in March \u2014 citing the energy shock directly. Fixed mortgage rates, which had been sitting around 4.83% for a two-year deal at the start of March, climbed to around 5.89% within weeks. Major lenders including Barclays and Nationwide pulled their sub-5% products and repriced almost overnight.<\/p>\n
For anyone with a mortgage \u2014 or planning to get one \u2014 this chain of events is not abstract. It translates into real numbers on a monthly statement. This article explains the mechanism clearly, shows what the numbers look like for different borrowers, and sets out what is worth thinking about now.<\/p>\n
<\/p>\n
Understanding why oil prices affect mortgage rates requires following a fairly short chain of cause and effect. Once you can see it, the connection becomes intuitive \u2014 and you can apply the same logic to future events.<\/p>\n
The conflict in the Middle East disrupted the production and transportation of oil and gas. The Strait of Hormuz, through which roughly a fifth of the world’s oil supply flows, was severely affected. Wholesale energy prices rose sharply in response.<\/p>\n
Higher oil and gas prices feed directly into the Consumer Prices Index (CPI). Fuel costs more at the pump. Transport and logistics become more expensive. Businesses face higher input costs and pass some of them on. UK CPI, which had been at 3.0% in January 2026, was projected by the Bank of England to rise to between 3.0% and 3.5% over the following quarters as a direct consequence.<\/p>\n
The Bank of England’s primary mandate is to keep inflation at 2%. When inflation is rising, reducing interest rates would add further stimulus to an already-pressured economy \u2014 making the Bank’s job harder, not easier. The March 2026 MPC meeting, which markets had been expecting to deliver a rate cut, instead resulted in a unanimous vote to hold at 3.75%. Traders moved from pricing in cuts to pricing in hikes \u2014 as many as two potential increases to 4.25% by year-end.<\/p>\n
The National Institute of Economic and Social Research has modelled the scenario directly: if energy costs remain elevated for a full year, they estimate the base rate could be pushed to 4.5%. Oxford Economics, meanwhile, believes the Bank will hold at 3.75% for the rest of 2026 and well into 2027. That is a significant shift from what was expected as recently as February.<\/p>\n
Most fixed-rate mortgages are not directly tied to the Bank of England base rate. They are priced off ‘swap rates’ \u2014 the rates at which banks and lenders can hedge their future interest rate risk in the financial markets. When markets expect rates to stay higher for longer, or to rise further, swap rates increase. Lenders respond by repricing their fixed-rate products upward, often within days. This is precisely what happened in March and April 2026. Industry commentary at the time made clear that the sharp change in the inflation outlook had already sent mortgage rates substantially higher \u2014 with markets now factoring in rate rises that were unthinkable just a few weeks earlier.<\/p>\n
<\/p>\n
Markets moved from pricing in cuts to pricing in hikes within the space of a few weeks \u2014 a shift in expectations that fed directly and rapidly into the fixed-rate deals available to borrowers.<\/em><\/p>\n <\/p>\n The scale of the repricing in March and April 2026 is significant. The table below compares average rates before the conflict began with where they stood in April 2026, using Moneyfacts data.<\/p>\n <\/p>\n Table 1 \u2014 UK average fixed mortgage rates: before and after the oil price shock<\/strong><\/p>\n Source: Moneyfacts industry data, March\u2013April 2026. Average rates across all LTVs. Best available deals will differ by loan-to-value, lender and individual circumstances.<\/em><\/p>\n To put those figures in practical terms: a borrower who locked in a two-year fix at the pre-conflict average of 4.83% is paying noticeably less each month than someone taking out the same mortgage today. The table below illustrates the difference across a range of loan sizes, based on a 25-year repayment mortgage.<\/p>\n <\/p>\n Table 2 \u2014 Monthly repayment comparison: pre-conflict rate (4.83%) vs April 2026 average (5.89%)<\/strong><\/p>\n Based on a 25-year capital and interest (repayment) mortgage. Figures calculated using the standard annuity repayment formula and rounded to the nearest pound. Pre-conflict rate of 4.83% and April 2026 average of 5.89% per Moneyfacts industry data. These are illustrative figures based on average rates \u2014 the rate available to you will depend on your loan-to-value, credit history and lender. Speak to an adviser for a personalised comparison.<\/em><\/p>\n Around one million fixed-rate deals are due to expire between April and September 2026, according to the Financial Conduct Authority. Many of those borrowers fixed in 2021 at rates below 3%. Coming off those deals now means moving to today’s rates \u2014 a difference that, as the table above shows, can amount to hundreds of pounds per month.<\/p>\n Sitting on your lender’s standard variable rate (SVR) while you wait for things to improve is rarely the right answer. The average SVR in April 2026 is 7.13% \u2014 considerably higher than even the current elevated fixed-rate market.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n There is genuine disagreement among economists and lenders about where rates go from here. That uncertainty is itself worth understanding, because it affects the decisions available to borrowers.<\/p>\n On one side, those expecting rates to fall point to the underlying UK economic picture: growth is weak, unemployment is at a five-year high, and the Bank of England’s own guidance before the conflict was firmly toward further cuts. If the conflict stabilises or resolves, energy prices could ease relatively quickly, taking inflationary pressure with them. Some forecasters suggest a September 2026 cut remains plausible in that scenario.<\/p>\n On the other side, Goldman Sachs and Citi have both revised their forecasts from three cuts in 2026 to none. ING’s James Smith predicts rates will stay unchanged throughout the year. The NIESR’s modelling suggests that if energy costs remain high for a sustained period, the base rate could reach 4.5%. JP Morgan has gone further, predicting a hike as early as June.<\/p>\n The honest answer is that no one knows how long the conflict will last, and therefore no one can say with confidence whether mortgage rates will be higher or lower in six months than they are today. The practical implication of this uncertainty is that waiting for a ‘better time’ to act carries its own risk.<\/p>\n The honest position, shared by many economists and market commentators, is that predicting the direction of mortgage rates over the coming months has rarely been harder. Those waiting for certainty before acting may find the window has passed.<\/em><\/p>\n <\/p>\n The right course of action depends entirely on where you are in your mortgage journey. The table below sets out the key considerations by borrower type.<\/p>\n <\/p>\n Table 3 \u2014 Your situation and what to consider<\/strong><\/p>\n <\/p>\n This is the question most borrowers are wrestling with right now, and there is no universal answer. What has changed is the risk calculation.<\/p>\n Before the conflict, tracker mortgages carried a certain logic: if cuts were coming, a tracker would follow them down without early repayment charges. That logic has now reversed. With the market pricing in potential hikes rather than cuts, a tracker exposes you to upward movement with little warning. The ‘best buy’ tracker sits at around 3.96% above Bank Rate today \u2014 attractive on paper, but that number moves automatically if the base rate rises.<\/p>\n Fixed rates offer certainty at a cost. The current two-year average of around 5.89% is higher than most borrowers would have hoped for at the start of the year. But a five-year fix at around 5.77% locks your payment for the duration, regardless of what happens in the Middle East, with swap rates, or at the next six MPC meetings. For households that need budgeting certainty \u2014 particularly those who have already stretched to afford their home \u2014 that predictability has real value.<\/p>\n Some borrowers choose to roll onto their lender’s standard variable rate and wait for a better deal to appear. The average SVR in April 2026 is 7.13%. On a \u00a3200,000 mortgage over 25 years, that is approximately \u00a31,416 per month \u2014 around \u00a3275 more per month than even the current elevated average two-year fix. That is over \u00a33,300 per year of unnecessary cost for every year spent on the SVR.<\/p>\n Unless you are very close to selling the property or have a specific reason to avoid fixing, the SVR is almost always the most expensive option.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p>\n It is easy, in a moment of market disruption, to assume the current situation is permanent. It is not. The UK has navigated significant energy shocks before \u2014 the 2021\u201322 crisis saw wholesale gas prices reach nearly 600p per therm, CPI inflation breach 11%, and the Bank of England raise rates 14 times in succession. Mortgage rates did eventually come down as inflation was brought under control.<\/p>\n The trajectory of rates from here depends primarily on three things: how long the conflict and its effect on energy supply persists, whether second-round inflation effects (businesses raising prices, wage growth accelerating) take hold, and how aggressively the Bank of England responds. None of those are knowable with certainty today.<\/p>\n What borrowers can control is how well-positioned they are for different outcomes. That means understanding exactly what deal they are on, when it ends, what the alternatives look like across the market, and whether their monthly budget can absorb a reasonable range of rate scenarios. A short conversation with a qualified mortgage adviser<\/a> can answer all of those questions quickly.<\/p>\n <\/p>\n Whether your deal is ending soon, you are on a variable rate, or you are simply unsure what the current market means for your mortgage, our advisers can give you a clear, personalised picture.<\/p>\n We will compare your options across the market and help you make a decision that is right for your circumstances \u2014 not just what the headlines suggest.<\/p>\nWhat has actually happened to mortgage rates<\/h2>\n
