treasury bills
The Spanish phrase 'Letras del Tesoro' is translated into English as 'Treasury Bills'. These are short-term debt obligations issued by a national government with maturity periods ranging from a few days to 52 weeks. They are sold at a discount from their face value, and don't pay interest per se. Instead, they are redeemed at their face value upon maturity. The return to investors is the difference between the purchase price of the bill and the amount paid out at maturity (or upon prior sale).
