Thanks.... I noticed it was sold at a discount
Are they all sold at a discount, or just not much interest in this one, this time.
Coupon rate is always in 0.125% increments. If the real yield isn’t evenly divisible by 0.125%, then they make up the difference by selling at discount.
In this case, the yield is 1.810% - 1.75% = 0.06%, which (should) equal the discount.
