Washington gave mortgage lenders a cheaper credit score, and FICO lost a quarter of its value
Fair Isaac, the company behind the FICO credit score, fell 26.52% to US$617.87 last Tuesday. That was its worst day since 1989, and the shares finished the week 23.4% lower at US$661.25.
The change sounds technical, and it reaches the core of the business. On Monday, Bill Pulte, who runs the Federal Housing Finance Agency, said Fannie Mae and Freddie Mac will price mortgages off one grid. VantageScore, a cheaper rival built by the credit bureaus, joins FICO Classic on it.
Until now a VantageScore had to be 20 points higher than a FICO score to earn the same loan price. That gap gave lenders a cost reason to stay with FICO, even after it doubled its mortgage price to about US$10 a score this year.

The rival costs a tenth of that. TransUnion will keep VantageScore 4.0 at 99 US cents a score until December 2028. Rocket Mortgage, the country's largest home lender by volume, will make it the default on eligible loans from this quarter.
FICO bounced 11.69% on Thursday. Mortgage bonds still require a FICO score, Yahoo Finance points out, so many lenders may keep paying for both.
how many lenders follow Rocket. I'd wait for a second big name to switch its default before judging how much of FICO's mortgage business is really at risk.
