Fixed mortgage rates have fallen week-on-week for the first time since the Iran conflict broke out on 28 February 2026, according to new data from Moneyfacts. The average three-year fix dropped 5 basis points (bps) to 5.5%, while the average two-year fix fell 3bps to 5.87% (Moneyfacts, 17 April 2026). For a portfolio investor managing multiple fixed-rate maturities, this is the first directional shift worth paying attention to in nearly seven weeks.
What the Rate Data Actually Shows
The headline figures understate the moves in some corners of the market. Average three-year fixes at 95% loan-to-value (LTV) fell 13bps to 5.98%, and at 85% LTV they dropped 9bps to 5.53%. Average two-year fixes at 70% LTV fell 9bps to 5.58%, while at 95% LTV they came down 8bps to 6.4% (Moneyfacts, 17 April 2026).
The average five-year fix also edged down 2bps from 5.78% to 5.76%. That is a smaller move, but the direction matters - five-year money had been stubbornly elevated throughout the conflict period.
Major clearing banks led the charge: HSBC cut by up to 34bps, Lloyds Bank by up to 35bps, and Santander by up to 28bps. TSB went furthest at up to 45bps, and The Co-operative Bank reduced by up to 33bps. Not every lender moved in the same direction - Kensington increased by up to 20bps and Principality Building Society increased by up to 23bps - so the market is still not moving uniformly.
Moneyfacts personal finance expert Rachel Springall attributed the moves to swap rates "hovering around 4%", which have softened since the ceasefire. Prior to that ceasefire, she noted, there had been "growing speculations for an interest rate hike by the Bank of England to respond to a projected hike in inflation." She was direct about the limits of this data point: "the future path of interest rates remains murky, and short-term respites can change quickly."
The Portfolio Angle on This Move
Interest rate movements do not just change your monthly payment. They change your entire refinance strategy.
If you hold properties at higher LTVs - the 85-95% range that building societies target for first-time buyers - the steeper cuts at those tiers are directly relevant to your buy-to-let stress test. A 13bps reduction at 95% LTV changes the interest coverage ratio (ICR) calculation for any deal you are stress-testing right now.
From a leverage play perspective, the return of higher LTV products matters beyond the rate. Cambridge Building Society launched new 98% LTV products this week, alongside 95% LTV ranges from Saffron Building Society and Leeds Building Society. For investors using the BRRR strategy (buy, refurbish, refinance, rent), the reopening of higher LTV tiers from building societies improves the refinance exit on projects that were stuck below lender thresholds.
The risk to the upside scenario is straightforward. Springall flags it directly: ceasefire dynamics can reverse. If the Middle East situation escalates again, swap rates will reprice within days and this week's cuts will be unwound just as quickly. Before committing to a strategy based on one week of rate data, review the negotiation and finance fundamentals for your deal type.
What to Watch Over the Coming Weeks
The signal to watch is not average rates - it is what the major clearing banks do next. When HSBC, Lloyds and Santander all cut in the same week, that usually creates competitive pressure on the rest of the market to follow. If Halifax (down up to 35bps this week) and Barclays move in concert over the next fortnight, this is likely the start of a sustained easing cycle rather than a one-week blip.
For portfolio investors thinking about strategy beyond the next deal, the property investment strategies guide covers how different financing environments affect hold versus sell decisions over the cycle. The free resources hub also has updated cashflow templates if you want to run current rate scenarios against your existing portfolio.
The rate environment is not fixed. Your response to it should be structured. One week of positive data does not call for a change of strategy - but it does call for a conversation with your broker.
