The FTSE 100 closed down 18.70 points, or 0.2 per cent, at 9,427.73 on Friday, snapping a four-day winning streak as Experian plunged on fears that Fair Isaac's new direct-to-consumer credit score push could erode bureau economics.
Tesco headed the blue-chip risers after lifting profit guidance, while Experian fell more than 4 per cent to £35.20 as mortgage technology investors reassessed how much intermediation credit bureaus can keep if lenders adopt FICO's distribution model. The FTSE 250 slipped 2.40 points to 22,047.30, and the AIM All-Share added 0.3 per cent to 788.95, reflecting continued appetite for smaller domestic names even as large caps paused.
Experian and the FICO challenge
Fair Isaac, the US firm behind the FICO score, outlined a programme that would let mortgage lenders calculate and deliver scores directly to consumers. Jefferies analysts warned the move could compress fees Experian and Equifax earn on tri-merge reports. Experian argued its data assets and identity-verification tools remain essential, but the market treated Friday's announcement as a structural risk rather than a one-quarter blip.
UK investors have seen this movie before in payments and open banking: whenever a dominant data intermediary faces disintermediation, multiples compress before incumbents prove they can sell adjacent analytics. Experian's London listing makes it a bellwether for that trade in Europe.
Tesco and the domestic bid
Tesco rose 3.2 per cent to 452.4p, dragging food retail sentiment higher. 3i, Rentokil Initial, Croda and ICG rounded out the top five gainers, a mix of private equity, pest control and speciality chemicals that pointed to a market still willing to pay for idiosyncratic earnings rather than pure macro beta.
On the downside, BT, Coca-Cola Europacific Partners, WPP and Fresnillo joined Experian among the biggest fallers. BT's slide came amid ongoing debate about fibre capex returns, while advertising-heavy names like WPP remain sensitive to any hint of brand budget cuts ahead of the November Budget.
Rates and the next session
Gilt yields were little changed into the close, but traders were positioning for the OBR's pre-measures drop and the Bank of England's Financial Policy Committee record, which kept the countercyclical capital buffer at 2 per cent. For FTSE allocators, the message was familiar: exporters and banks trade the dollar and rate path, while domestic retailers trade the UK consumer. Friday's split between Tesco and Experian encapsulated both books in a single settlement print.
