Santander and HSBC have both reduced mortgage rates on residential and buy-to-let products as swap rates ease. Two major lenders moving in the same direction at the same time is a meaningful signal — here's what it means and what contractor borrowers should do with the information.
What swap rates are and why they matter
Fixed mortgage rates are priced off swap rates — the rate at which banks lend to each other over a fixed term. When swap rates fall, lenders' cost of funding fixed-rate products falls, and pricing typically follows with a short lag. This is the fundamental mechanism behind fixed mortgage rate movements, and it's why watching two or five year swap rates is a better leading indicator of where your mortgage will be priced than watching the Bank of England base rate.
Swap rates are themselves driven by market expectations: future Bank of England rate moves, inflation data, and global bond market conditions all feed in. When two major lenders cut simultaneously, it usually means swaps have moved enough to make repricing commercially necessary — not a gesture of goodwill, but a response to genuine shifts in their funding costs.
What this means in practice
Two-year and five-year fixed rates are likely to edge down across more lenders in the coming weeks as others follow Santander and HSBC. When the two largest movers go first, the rest of the market typically reprices within a fortnight. The precise timing varies, but the direction is clear.
This is a different dynamic from the split market described when HSBC cut earlier while others were rising — that was one lender moving against a rising tide. This is a broader directional shift driven by underlying funding costs. The distinction matters: a split market requires whole-of-market expertise to navigate; a directional shift creates opportunity across more of the panel simultaneously.
Contractors who locked in recently aren't necessarily worse off. Certainty had real value when rates were volatile and the direction was unclear. Those still deciding now have slightly better options than a month ago — and potentially better ones still in the next few weeks as the repricing continues.
The contractor decision right now
If you're within six months of your current fix ending, start the process now. You can often secure a rate three to six months ahead of completion and switch if something meaningfully better appears before you complete. This gives you downside protection (if rates rise, you're covered) with some upside optionality (if rates fall further, your broker can track and switch within window). Don't wait until the last month of your fix to start — contractor mortgage applications take longer than standard cases.
If you're buying, get your AIP in place and let your broker track rate movements. Trying to time the bottom of a rate cycle precisely is less important than being mortgage-ready when you find the right property. The cost of missing a purchase because you weren't AIP-ready is usually higher than the cost of locking in slightly before the bottom.
If you're on a variable rate, this is the most time-sensitive position. Rates may fall further as swaps ease — but the certainty of fixing now versus the possibility of saving a little more by waiting is a risk assessment, not a certainty. Variable rate holders are exposed to any upward move in the interim. The case for fixing is stronger the longer you expect to stay in the property.
Why this matters differently for contractors
Not all lenders pass swap rate improvements through to contractor-assessed products at the same pace or in the same proportion. Some specialist contractor lenders are slower to reprice; some high street lenders price contractor products off a different book from their standard residential range. The headline rate cut from Santander or HSBC may not be the rate a contractor actually accesses at the loan size they need.
A whole-of-market broker tracks these movements across the full panel — not just whoever happened to issue a press release. As swap rates ease and lenders reprice in sequence, the best available option for a contractor on day rate income may shift week to week. That requires active monitoring, not a one-off comparison site check.
