Quote 'Treasury + spread' from Monday's curve, not last month's
Many commercial loans and equipment leases are priced as a spread over a Treasury tenor. Curvewire gives your desk every tenor from the Treasury's own file each Monday, with how far it moved.
How lending and leasing teams use Curvewire Brief
- Open the curve table and find the tenor that matches your term (for example 5y for a five-year lease).
- Check the 1-week change to see whether quotes from last week need refreshing.
- Load the curve CSV into your rate sheet and add your spread.
- Use the 52-week range when a client asks whether rates are high or low.
In the 27 Sep 2026 edition the 5y yield was 4.98%, up 122 bp in 52 weeks; a 5-year quote built on last year's curve would be far off.
The brief is information only; your credit policy sets the spread.
