Where can I find interest rates for zero coupon bonds and Strips ?

Strips are sold in the marketplace as "Treasury zeros" or treasury zero coupons. They are called zeros because purchasers do not receive interest payments. The Treasury does not issue or sell Strips. They can be purchased through broker/dealers and depository institutions. They are the people to contact for rates. Bid and ask quotes and ask yields for US Treasury Strips are in the Wall Street Journal under the table "Treasury Bonds, Notes and Bills." These tables are in other financial reporting newspapers as well.
