Is a treasury bill a gilt?

A treasury bill (T-bill) is a short-term government debt security issued by the U.S. Department of the Treasury, while a "gilt" refers specifically to government bonds issued by the United Kingdom. Although both T-bills and gilts are considered low-risk investments backed by their respective governments, they are distinct financial instruments from different countries. Thus, a treasury bill is not a gilt, but both serve similar purposes in their respective markets.
