Halifax, part of Lloyds Banking Group, raised two-year fixed residential mortgage rates by 0.25 to 0.35 percentage points on Monday after five-year gilt yields and swap rates jumped through the second week of September, pushing a typical 60 percent loan-to-value two-year fix to about 5.24 percent for fee-paid products and higher for low-deposit tiers, according to rate sheets advisers received overnight and reviewed by InfoHandle. The move is priced off funding costs, not a discretionary margin grab—Halifax’s bulletin tied changes directly to swap curves lenders use to hedge fixed-rate books.
What changed in pounds on the statement
For a £250,000 loan over 25 years, a 0.30-point rate rise adds roughly £42–£45 to the monthly payment depending on capitalisation of fees. Halifax kept product fees stable on core tiers; the pain is in the annual percentage rate borrowers actually service. Tracker and standard variable rates were untouched in this sheet—only fixed ladders moved. Existing Halifax fixed-rate customers mid-term are unaffected unless they port or borrow more.
Borrowers with 25 percent equity saw the sharpest bumps on sub-5 percent promotional tiers that had been loss-leaders in August; 10 percent deposit products were already priced wider and moved less in absolute terms but remain above 5.6 percent on many bands. Buy-to-let two-year fixes moved in parallel on a separate sheet brokers access through intermediary portals.
Why swaps moved the ladder
Fixed-rate mortgages are funded in capital markets against interest-rate swaps. When five-year swap rates rise—even if Bank of England policy is on hold—lenders reprice new business to protect net interest margin. September’s spike followed stronger-than-expected US labour data and gilt supply nerves, not a UK base-rate change. Halifax’s note said repricing was “automatic within risk limits,” implying some tiers hit circuit breakers that require same-day uploads to broker portals.
Advisers said five-year fixes moved less than two-year ladders on Halifax’s sheet because swap steepness favoured shorter hedges—borrowers chasing payment certainty for a full five years may still see larger jumps if the curve steepens further. Green-mortgage add-ons and EPC-linked discounts were not withdrawn Monday; only core pricing grids changed.
Who is hit and who is not
Existing fixed deals stay until term end; this is for new applications and product transfers. Remortgage customers within 180 days of deal expiry can sometimes lock prior rates if they applied before Monday’s cut-off—brokers should check reservation timestamps. First-time buyers using Help to Buy ISA bonuses are unaffected by rate mechanics but face affordability stress tests that use the higher pay rate.
Shared-ownership staircasing applications use the same swap-linked grids; housing associations said Monday’s move does not change rent formulas but does raise mortgage costs for buyers increasing equity shares this autumn. Offset mortgage customers see no change to linked savings rates in this bulletin—only fixed-product pricing moved.
What to do before applying
Get a mortgage in principle refreshed; old MIP figures used August swaps. Compare fee-free higher-rate products against fee-paid lower rates on your exact loan size—Halifax’s spread moved non-uniformly across LTV bands. If you are on SVR considering a fix, remember fixes carry early repayment charges; the swap spike may ease if gilt yields retreat, but lenders rarely reverse hikes quickly once live.
Brokers and reservation windows
Intermediaries said Halifax kept product reservation windows open until 23:59 Monday for applications already submitted with complete paperwork—check your case tracker, not headline rates. New submissions after the cut-off price on Tuesday sheets. Some networks are lobbying for 48-hour grace on remortgage chains where valuations slipped because of surveyor backlog; Halifax has not announced an extension beyond standard policy.
Competitors including Nationwide and Santander repriced some tiers the same morning; Halifax is not an outlier, which suggests swap-driven industry moves rather than a Lloyds-specific funding gap. UK Finance industry data still shows approval volumes recovering from 2023 lows; higher rates bite demand, but Halifax’s move is supply-side pricing, not a credit crunch. Lloyds group brands including Scottish Widows Bank mortgage arm mirrored Halifax tiers on identical LTV bands where products are shared.
For households shopping this week, the actionable fact is on the rate sheet: two-year fixes from Halifax cost roughly a third of a point more than last Friday because September swaps moved—not because your credit score changed overnight.
