12 C.F.R. § 201.107
(b) The basis of that ruling was the provision in the second paragraph of section 13 of the Federal Reserve Act that notes, drafts, and bills of exchange must have a maturity at the time of discount of not more than 90 days, exclusive of grace. The ruling stated that
a demand note or bill is not eligible under the provisions of the act, since it is not in terms payable within the prescribed 90 days, but, at the option of the holder, may not be presented for payment until after that time.
(c) It is well settled as a matter of law, however, that demand paper is due and payable on the date of its issue. The generally accepted legal view is stated in Beutel's Brannan on Negotiable Instruments Law, at page 305, as follows:
The words on demand serve the same purpose as words making instruments payable at a specified time. They fix maturity of the obligation and do not make demand necessary, but mean that the instrument is due, payable and matured when made and delivered.
